The convoy carried not many temperature-pressure bombs and dared not use them at will. After the surrounding mutant beasts lost the suppression of the temperature-pressure bombs, they attacked again. The more and more they gathered on the periphery, the convoy could not even retreat. If this continues, there will always be times when the ammunition is exhausted and the artillery will be damaged overheated. At that time, except for a few people, others may be buried here.

A mutant beast corpse was piled up in front of Chu Xiang and the others, and the group of beasts was still constantly rushing to the convoy's defense line, fearing death.

"The gunfire support will arrive in ten seconds, and everyone will withdraw back to the car." Staring at the time on the watch, Song Ming ordered.

After receiving the order, the warriors on the roof of the car returned to the chariot, losing the suppression of the firepower on the roof of the car, and the attacking mutant beasts became even more ferocious.

“Ten, nine, eight, seven.”

“Six, five, four, withdraw.”

Song Ming turned over and rushed into the chariot. At the same time, Zhang Zhen, Bian Chu Xiang and others retreated into the chariot. Everyone covered their ears tightly, and at the same time opened their mouths, waiting for the arrival of artillery fire support.

As soon as everyone retreated into the car, there was no suppression of firepower. The mutant beasts rushed in from all directions. The zombie army formation that was bombed into the cliff also gained a chance to breathe and gathered to advance again.

Just as the mutant beasts were flooding the convoy, the sky shells suddenly fell like rain, and the rumbling explosion shocked the earth, plowing the entire valley and the surrounding hills, and then the sharp sound of breaking through the air sounded.

The earth was shaking, the smoke and dust covered the sky and the sun, and the flames were beating. The four chariots shook like small boats in the sea in the terrifying explosion, and all the affected mutant beasts were torn into pieces. The plowing land was not stopped, and the last batch of shells exploded directly in the air of 300 meters, burning the entire sky into blood red, and it turned out to be air-explosive temperature-pressure bombs.

This is the real saturation coverage attack. Except for the 100-meter-long meter surrounding the four chariots, everything else in the entire valley was leveled. Fortunately, the positioning of the artillery fire was very accurate, and none of them fell within 100 meters of the convoy. Even so, everyone in the chariot was frightened.

"Each unit reports the results of the battle." Song Ming's voice sounded in the rolling smoke and dust.

"Ninety-five percent of the mutant beasts cleared."

"The army was destroyed."

"The zombies are intact and are approaching."

Hearing that the zombies were approaching, Zhang Zhen and Chu Xiang immediately rushed out of the chariot and prepared to fight. With the combat power of the zombie, if it is approached by it, a slap can destroy a chariot.

In the thick smoke, the ground was full of infrared residues after bombing. The main gun of the chariot could not lock in the position of the zombie generals, and the remote-controlled machine gun could not keep up with the speed of the zombie. Just as the seven people came out of the car, the zombie had crossed hundreds of meters and approached the No. 34 chariot on the left.

"Damn." Zhang Zhen shouted angrily and waved his fist to meet him, and Chen Ying also took action.

Unexpectedly, everyone was not hurt at all. Seeing Zhang Zhenbian and the two of them coming towards him, the zombies drew out their swords and the sword light poured down. The two of them hurriedly dodged.

The war broke out again, Zhang Zhenbian and Chen Xingli fought against zombies, Qin San and Chu Xiang protected a chariot one by one to prevent zombies from jumping over the wall. After a big battle, Zhang Zhenbian and Chen Ying defeated the zombies again, Chu Xiang and Gongsun Qi stepped forward to help, and the four of them pressed the zombies tightly. The zombies kept struggling, roaring and dust flying, unable to get rid of the internal strength of the four people, and were pressed several feet into the ground by the four people. Qin Santong seized the opportunity and hurried forward, pinched a handprint, pressed it on the zombie's forehead, and fed some pills to the zombie who were unknown.

After Qin Santong tried it out, the zombie stopped struggling, the red light in his eyes dissipated, and he closed his eyes.

"Huh! This guy is really resistant to beating!" Zhang Zhen shouted. The two of them twisted their arms when they were almost struggling by the zombies, turned to Qin San and said, "Isn't this guy so corpse poison like on TV, right?"

Qin Santong smiled and said, "TV is a TV, but if you are bitten by it, you will not become a zombie, but will be sealed with blood."

"No, it's even more poisonous than on TV!" Zhang Zhenbian jumped up in fear and quickly looked at his hands.

"Don't worry, his skin is good, and it's not so easy for the toxins to escape. The toxins in his body have condensed into solid form, and they are also copper-skinned iron bones, so it is basically impossible to leak out." Qin San said.

To control the zombies, several people tied the zombies like rice dumplings with various equipment that had been prepared. The soldiers unloaded a huge cylinder from the car, and Qin Santong carefully placed the zombies into the cylinder and sealed them.

After dealing with the zombies, looking at the messy valley, Qin San said, "Song Ming, you give the equipment to them three, and you are ready to pick it up here."

"Yes." Song Mingdao.

"Brother Zhang, Brother Chen, Chu Xiang, Shi Wuzheng, Gongsun Qi, let's go into the cave to explore." Qin San said.

Several soldiers moved a bunch of things out of the car, including some lighting monitoring equipment. Gongsun Qi and Shi Wuzheng were both top students. After a brief explanation from the soldiers in charge, the two of them knew how to use these things.

What made Chu Xiang embarrassed was that Nurse Xiaoting was responsible for handing over some medical things with him. Chu Xiang didn't dare to look at the woman in front of him, his eyes were just nailed to the ground, and he kept taking all kinds of things stiffly, not daring to touch her hand at all. The cold voice seemed like a death-hunting, with a stubbornness that tried his best, which made Chu Xiang extremely embarrassed. Fortunately, it was just two ways to use antidotes and it was handed over quickly.

After a while, the two of them had handed over. Chu Xiang and the other two took the equipment and the six were careful to go to the cave. The valley bombed by artillery fire was in a mess, and the corpses of the mutant beasts were piled up for unknown amounts. Every step was stepped on the corpse, and the entire valley turned red and smelled sour.

The three of them had just walked away and didn't want to show their weak side in front of Chu Xiang. Nurse Xiaoting, who was holding back the nausea, finally couldn't help but start vomiting. Chu Xiang couldn't help but sigh, feeling extremely uncomfortable.

"Know?" He captured Chu Xiang's sigh and Gongsun Qi asked.

Chu Xiang nodded and shook his head.

"Then why are you sighing?" Gongsun Qi's expression was strange and he continued to ask.

"This world is not suitable for women." Chu Xiangdao.

"When did our Mr. Chu become so compassionate?" Gongsun Qi smiled.

"What, don't you give me?" Chu Xiang condemned.

"I don't dare." Gongsun Qi said with a haha.

The zombie army formation approaching the mountain bag, the two of them did not dare to be distracted and looked around intently.

Qin Santong carefully checked the broken puppet soldiers of the military formation, frowned, and didn't know what they were thinking. After a long time, he said to Chen Ying: "Brother Chen, please go in and vent again, safety is the priority."

The puppet army formation was almost completely destroyed. Except for a few puppet army soldiers intact, the others were blown to pieces and unrecognizable.

"Okay." Chen Ying nodded and entered the cave again.

After Chen Ying entered the cave, after a while, the cold air surged out of the cave and everyone hurriedly avoided it.

"There shouldn't be anything inside, right?" Zhang Zhen said.

"Who knows, it's best to be careful." Qin San said.

"A such thing is already amazing enough. If there are a group of people, that would be fine." Zhang Zhen said on the side. Before he finished speaking, a sudden rumbling sound in the cave, like wind and thunder.

"Damn, there is really something." Zhang Zhen's face changed, gathered his energy and prepared for the battle.

Qin Santong waved his hand and Chu Xiang and the other two retreated quickly.

After a while, Chen Ying rushed out of the cave with a look of shame.

Everyone was preparing for the battle intently, but nothing came out.

After a while, Qin Santong asked, "What's going on inside?"

"There is one more." Chen Ying said in a deep voice.

"Sure enough, this is a little troublesome." Qin Santong stroked his long beard and said.

"Please let me go in and beat it up." Zhang Zhen shouted.

"That's all." Qin Santong nodded.

"Do you really want this?" Unexpectedly, Qin Santong said this, Zhang Zhen stared at Qin Santong. Damn, this old boy, cheated me, and thought to myself that he must not show guilt, otherwise he would be laughed to death by several juniors.

"What's the solution? This is obviously a layout of one master outside and one master inside. This guy will definitely not come out, so you have to go in and beat it up." Qin Santong said helplessly.

"Okay, let's see if I won't beat it half to death." Zhang Zhenbian said hatefully and walked towards the entrance of the cave.

"Senior, be slow, the enemy is in the dark, I am in the bright, so don't be impulsive." Chu Xiang spoke at the right time and rescued Zhang Zhenbian.

Zhang Zhenbian stepped down and nodded, "Yes, the enemy is secret and I am not easy to do anything. Just make plans properly so as not to ruin major issues."

Qin Santong smiled and turned to ask Chu Xiang: "What do you think?"

Chu Xiang said without hesitation: "Every step by step, if it doesn't come out, we will force it in and take the lead."

"Okay." Qin Santong nodded.

Zhang Zhenbian and Chen Ying opened the way, and Qin Santong followed closely behind. Chu Xiang Gongsun Qi and Shi Wuzheng installed various lighting and camera equipment all the way on the wall of the cave, making the cave clear.

The six people worked step by step, installing lighting and camera equipment along the way, slowly advancing deep into the cave. The cave is very deep and very large. After entering more than twenty meters, the width of the cave is already more than thirty meters and more than ten meters high. High-power lighting equipment cannot fully illuminate the cave.

Infrared detectors, thermal energy detectors, and various other equipment that are unknown, Chu Xiang and the other two installed all the things they brought in in the cave, forming blind spot monitoring of the entire cave.

The deep hole was covered with white bones, and there were shattered gravel everywhere. Every step was stepped on it, it fell on the bones. Qin Santong shone the deep into the darkness. In the mist, it was vaguely visible that there was a flat stone slab at the end.

"Be careful, it's coming soon." Chen Ying reminded.

Chu Xiang and the other two installed lamps and shone the depths of the cave as if they were daylight, but there were no zombies. No abnormalities were found in the infrared detector and the thermal detector.

Zhang Zhen walked forward cautiously, and everyone covered each other. When they approached the stone wall at the bottom of the cave, they could already see the words on the stone wall. The zombie attacking Chen Ying still did not show up.

Ha. A gentle exhalation suddenly sounded in the cave, and a strong wind hit Zhang Zhen's side, and then a strong wind blew on the right cave wall, rolling towards Chen Ying.

Zhang Zhen turned around and punched the fierce wind, and swept the zombie that attacked Chen Ying with a whip.

The fists and feet intersected, and the three sides were about to part. Zhang Zhenbian and Chen Ying retreated and were on guard. The zombie who appeared also took a few steps back, facing the stone wall, and his blood-red eyes were extremely charming under the light.

Another tall and mighty zombie, wearing heavy armor, long sword hanging on her waist, and a mighty domineering zombie. Although it is not as powerful as the previous one, the desolate aura is even better than that.

"Kill." Zhang Zhen roared, the zombie pushed out with his palm, the fist and palm were intersecting, the strong wind whistled, the strong wind blew, and the rocks fell above his head like rain.

With one blow, the zombie remained motionless, as steady as Mount Tai. Zhang Zhenbian was knocked back more than a meter, and his feet dragged out two deep dents on the hard stone floor.

This zombie is obviously stronger than the previous one. Zhang Zhenbian's blood is surging, so he is cautious and dare not take action for a while. The zombie does not pursue it, which is strange.

Seeing the zombie act like this, everyone understood that it must be protecting something behind it. The cave seemed even more mysterious than expected.

I don’t know if there is anything strange about this strange cave. The current situation is that there are so many dreams. Qin Santong made a quick decision and said, “Two guys, let’s go together.”

Qin San drew his sword together, and three top masters stepped on together. Suddenly, the strong wind in the cave stormed and the earth shook.

The zombie immediately drew its sword, and the long sword in its hand poured down like a Milky Way. The sword energy was scattered. Qin San and Zhan Lu were in their hands, not afraid at all. Zhang Zhenbian and Chen Ying were facing the enemy empty-handed, but it was difficult to break through the sword net. The zombie was trying to hold on and did not pursue it. For a moment, the three of them could not attack.

Even though the zombies are invincible, they are powerful and powerful. They are unable to defeat six hands with two fists and are unable to withstand the siege of three masters. After a few minutes of stalemate, the zombies began to fall into decline and could not resist the situation. The sword was shot down and then knocked down. The three of them rushed forward and hugged the zombie's hands and feet.

Seeing this, Chu Xiang and the other two hurriedly stepped forward to help. Gongsun Qi hugged the zombie's legs tightly, allowing Qin Santong to free up his hand. Chu Xiang and Shi Wuzheng held the zombie's head and asked Qin Santong to cast a spell to deter the zombie.

After fiddling with the uniform zombies, he tied up the zombies with steel cables. Qin Santong carefully checked the cave and confirmed that there was no other existence. Then he returned to the stone wall and studied the words on the stone wall.

There are six small seal scripts engraved on the door: Chu Xiang only understood three things: *Tian*, Jiuzhou*.

Qin Santong brushed away the dust from the stone wall. The five of them stood behind, not daring to act rashly, for fear of touching the mechanism above. After brushing away the thick dust, everyone realized that the stone wall was not a stone wall, but a stone door, and there was a groove on each side of the door that was one person high.
