Consciousness returns to the cave body, and Wang Xing soon saw an additional resource on the resource panel: the origin of the world, five units.

"Is the origin of the world? What's the thing? I don't know if the advanced skeleton can be modulated with the origin of the world. If it can't be, it would be a big loss." Wang Xing murmured and pulled the panel to the interface to modulate the advanced skeletons, and chose a type and name at will.

, skip the face-pinching process and enter the required resource panel at all levels:

The seventh-level bone essence is 10,000 units, the soul stone is 1,000 units, and the world's origin is one unit.

Eighth-level bone essence 50,000 units, soul stone 5,000 units, and world origin three units.

The ninth-level bone essence is 100,000 units, the soul stone is 10,000 units, and the world's origin is five units.

"It's okay, but the origin of the five-unit world can only modulate one ninth-level high-level skeleton." Wang Xing breathed a sigh of relief, and at the same time, there was a new question in his heart.

This time, we have gained a total of five units of the world's origin, which means that the Qingtian battles the ape demon core contributed three units and the double-headed mad wolf demon core.

But Wang Xing remembers that the Ice Demon Tiger should be a seventh-level monster, but the magic core modulates Dian Wei at the peak of the eighth-level, or is it a loss in the process of collecting the magic core.

Then he denied the statement of loss and thought to himself: "There should be something else I don't know, but unfortunately I know too little about this world."

After not finding the answer, Wang Xing no longer struggled. Maybe he would understand the world more in the future and the problem would be solved.

Retrieve the basic skeleton star and prepare to take Dian Wei out to find a hidden place to increase the level of the Death Bone Pit.

But before he could walk out of the city lord's mansion, a message came from a skeleton soldier left deep in the 100,000 mountains. The monster did not disperse and gathered again.

"The beast tide is not over yet." Wang Xing raised his eyebrows, showed a playful smile, withdrew his right leg that he had stepped out, and let Dian Wei leave the city alone, while he walked towards the lobby of the city lord's mansion.

The hall was empty. After asking, I found out that Liu Cheng mainly comforted the people in the city, and Jin Yujiao also looked at him.

"You, take a few people to find the princess or City Lord Liu immediately. The situation is urgent." Wang Xing walked out of the City Lord's Mansion and remembered that he seemed not familiar with this place, so he called the soldiers standing guard beside him and said.

"Yes." The soldier did not hesitate and then clicked a few people to run away.

Soon, Jin Yujiao came over with Zhou Qian and Aunt Xue, and said in a panting voice: "Wang Xing, why are you looking for me in such a hurry?"

"Go inside to talk." Wang Xing walked towards the hall. He felt that it would be better not to say things that were not over in public, so as not to cause panic.

Seeing that he looked solemn, Jin Yujiao didn't seem to be joking. She immediately knew that the matter was important, so she didn't ask much and followed her to the hall.

"The skeleton soldiers I left in the 100,000 mountains came from a message saying that the monsters had not dispersed." Back at the hall, Wang Xing whispered.

"Are you sure?" Lord Liu, who had just rushed back and had not yet entered the door, said anxiously.

"Unsure, the information coming from is too vague." Although Wang Xing didn't know much about this world, he also knew that the necromancer's sense of vague skeleton soldiers who were too far away was very vague.

"I'll ask someone to check it out immediately." City Lord Liu, who had not entered the door, turned around and walked out again.

"It's better to go deeper, there are disguises made by monsters on the outside." Wang Xing reminded in time.

Within a hundred miles outside the city, monsters often run around and hunt, which looks no different from usual.

"In addition, notify everyone to prepare for evacuation." Aunt Xue also reminded.

"We are going to abandon the city?" Wang Xingbiao said curiously.

"Well, if the beast tide is just the beginning, we will only repel the forward, and there will be high-level monsters. Then the beast tide behind will definitely have super-level monsters. We can't defend it at all, and we will definitely die. Now we may still be able to leave.

Before the beast tide broke out, there was still a glimmer of life to arrive in Luocheng." Zhou Qian looked down, but she still explained to Wang Xing.

"And if there is a disguise made by monsters outside the city as you said, then this beast tide is definitely not simple. Wang Xing, I need your skeleton soldiers to stay and cut off the rear for us." Aunt Xue said.

"Okay, I will leave some skeleton soldiers behind." Wang Xing thought for a while and had no reason to refuse, and responded.

“I’m talking about it all.”

"Impossible." Wang Xing subconsciously refused.

"Ten thousand kilograms of soul crystal stone." Aunt Xue smiled.

Upon hearing this, Wang Xing twitched his mouth and kept roaring in his heart. It’s amazing that there is a mine at home!

"I'll think about it." In the end, Wang Xing surrendered. He didn't have the courage to refuse. It was amazing to have a mine at home. Who made him have no mine at home? But he wanted to get some other benefits.

"Yes, it's better to be faster." Aunt Xue seemed to see something, and she didn't urge her, and said with a smile.

Wang Xing sighed in his heart that Jiang is still so old!

As the news spread, the city fell into chaos again, and Luo Qing, the shopkeeper of the Bauhinia Chamber of Commerce, also rushed to the city lord's mansion to inquire about the news.

Waiting is always the longest and most difficult, but all of this has nothing to do with Wang Xing. He received the hidden news from Dian Wei, and his consciousness had returned to his original body.

In front of the Death Bone Pit, a dark blue light enveloped Wang Xing and the Death Bone Pit, and endless energy continued to wash away Wang Xing's body and soul.

"Well, it's great." The faint light dissipated, Wang Xing stretched, and his bones all over his body made a crackling sound.

Death Bone Pit: Level 4, can recover 1,000 basic skeletons and 1,000 units of soul stones every day.

Resources required for upgrading again: 500,000 units of bone essence, 5,000 units of soul stone, 10,000 units of heart of the undead, and 1,000 units of space crystal.

"Space crystal, I hope it is not the crystal used to make space rings." Wang Xing had a very bad premonition.

Space crystal is sold in a gram of 10,000 gold coins per gram, and there is still no market price.

"Forget it, I'd better see how many resources are left first!" Wang Xing opened the resource panel, and this upgrade almost exhausted all resources.

The bone essence is only a pitiful 523 units, 320 units of soul stone, and 1,030 units of soul crystal. As for useless resources such as stones and wood, they have long been thrown out by Wang Xing.

It's right.

After reading the resources, Wang Xing opened the arms panel again. The fourth-level spear skeleton needs sixty units of bone essence, ten units of soul stone, and the fourth-level longbow skeleton needs fifty units of bone essence and fifteen units of soul stone.

"Modify a fourth-level spear skeleton." Wang Xing ordered.

Soon, a fourth-level spear skeleton stood on Wang Xing's face, but Wang Xing's face looked a little ugly. Although this fourth-level spear skeleton is stronger than the third-level skeleton, it is not much stronger. Not to mention the same level, it is the third-level peak.

It is estimated that all warriors can fight seven or eight.

"It seems that it's time to modulate a research-type advanced skeleton." Wang Xing muttered, but he started to have a headache again as the remaining resources were left.

The research type is a higher skeleton that is strengthened by the spiritual category, and the number of soul stones required is by no means a decimal.

"Stop reviving the basic skeleton and produce soul stones with all their might." Helplessly, Wang Xing could only grit his teeth.

This was discovered by him unintentionally. As long as the basic skeleton stops reviving, the output of soul stones will double, but it cannot be reversed. The daily number of basic skeletons recovers is certain, and even if the soul stones are not needed, it will not increase.

He was not worried about bone essence. So many monsters died outside the city, and he had time to collect them when the people in the city left.

This time he also received some other information, such as the death bone pit being upgraded to level 4, the collection ability of the basic skeleton will be increased tenfold, each collection resource will reach 10,000 units per day, and the number of troops will be increased.

After dealing with the matter in the cave, Wang Xing's consciousness relocated to the flesh and blood puppet. At this moment, a burst of rapid footsteps came from outside, breaking the silence of the hall. Everyone turned their heads and looked out the door.

A soldier ran into the hall and said, "The city lord, it has been investigated and there are indeed signs of an outbreak of beast tide, but..."

"It's just something? Tell me quickly." Lord Liu shouted anxiously.

"Here, the signs of the beast tide's outbreak are not very obvious. It is impossible to determine whether the beast tide will really explode. It requires more careful investigation."

"It's too late, everyone will leave the city immediately and we will withdraw back to Luocheng." Aunt Xue stood up decisively and said, "She must consider Jin Yujiao's safety, not be careless at all, and will not take risks easily.

"But..." City Lord Liu was a little hesitant. If the beast tide did not erupt, then he would have abandoned the city for no reason and would be punished.

"Just in case, I will explain to Your Majesty." Aunt Xue knew why City Lord Liu was hesitating and immediately decided.

"Okay." With Aunt Xue's guarantee, City Lord Liu nodded without hesitation. After all, no one wants to die.

"Well, there is a small airboat in our chamber of commerce that can plant ten people. If the princess doesn't dislike it, she can take the airboat first." Luo Qing coughed lightly.

"Okay, then I'll trouble the shopkeeper Luo." Aunt Xue said without waiting for Jin Yujiao to speak.

"You're welcome, I'll go and prepare first." Luo Qing said as he walked out of the hall.

"Wang Xing, how are you thinking?" Seeing Luo Qing leave, Aunt Xue's eyes stared at Wang Xing again.

"But yes, but 10,000 kilograms of the Dead Soul Crystal is not enough, I have other conditions." Wang Xing said slowly.

"What conditions? Let's hear it."

"One thousand kilograms of space crystal." Wang Xing said without hesitation.

Now I don’t know what the conversion ratio is. If it is a kilogram to convert one unit, Wang Xing feels that he will probably not be able to make up for it in his life.

Upon hearing this, Aunt Xue looked at Wang Xing seriously and said angrily: "That's it, I can't afford your skeleton."

After saying that, the man stood up and walked out.

Wang Xing was also stunned. Unexpectedly, Aunt Xue refused so simply. She sighed inwardly, and she still underestimated the preciousness of space crystal.

Zhou Qian came over at the right time and said, "Brother Wang Xing, the space crystal is extremely rare, I'm afraid that the entire kingdom will not be able to find a kilogram."

"Then let's change to other conditions." Wang Xing said with a embarrassed smile.

"Say." Aunt Xue, who was about to go out, stopped, turned her head and coldly looked at her pretty face, and spit out a word.
