Indeed, if a person is locked in a dark and dark enclosed space for a long time, his mental pressure will increase.

Not to mention, Zhang Zichen and the others were trapped in that underground space first, but now they have come to the underground undercurrent. How many years have passed and how many things have happened during this period.

With this huge pressure, it was already lucky that Zhang Zichen and the other five were unable to torture the enemy crazy.

Time flies. Although it seems that it is only a blink of an eye, Zhang Zichen and the others have been in the undercurrent underground for ten hours.

During these ten hours, the journey of Zhang Zichen's team was only the journey of Zhang Zichen three hours ago.

This is really slow.

Zhang Zichen walked in the front and looked back at the people behind him, with an anxious look on his face.

If they continue to move at this speed, they are afraid that they will really not be able to get out of this underground undercurrent and may die here, which may not be necessary.

Zhang Zichen, who frowned, coughed twice and reminded him through the sound transmission technique: "Sister Lu, our speed is too slow."

"Slow?" Tan Lu said, "But I think it's very fast!"

"This..." Zhang Zichen smiled bitterly, glanced at Feng Ruotan and others, and said, "Sister Lu, I'm not to hide it. Some time ago, I went into this underground undercurrent alone, and I've been here too..."

When everyone heard this, they were stunned.

Zhang Zichen has reminded everyone more than once that he has been investigating the underground undercurrent and staying for six and a half hours.

In the first three hours, Zhang Zichen was wandering upwards, which means that the journey that everyone took ten hours was not as good as that of Zhang Zichen alone.

This...is really speechless.

Tan Lu smiled awkwardly and said, "Zhang Zichen, are you kidding? I think our speed is already fast enough? How could it take ten hours to walk your three-hour journey?"

"Yes, Brother Zhang, you must be lying to others, right?" Feng Ruotan also didn't believe it.

Zhang Zichen knew that Lu Wenxing and Mao Zhijing would definitely not believe it.

Before the latter two were spoken, Zhang Zichen asked back: "Sister Lu, think about it carefully, is our speed fast or slow?"

"Uh..." Tan Lu thought for a while.

Since their group entered the dark underground undercurrent from the entrance of the waterfall, they have been chatting and moving forward. Along the way, everyone has been careful and searching everywhere.

Sometimes people stayed because of curiosity, and sometimes because of fear, the overall slowdown...

This speed doesn't seem to be very fast.

Thinking of this, Tan Lu smiled bitterly, "I...hehe... I saw that everyone was talking and laughing before, but I didn't care about the length of time."

"Then you figured it out now?" Zhang Zichen asked.

"I understand, our speed is indeed slow enough." Tan Lu smiled with a pursed lips.

"Where are you?" Zhang Zichen turned around and looked at Feng Ruotan and others, but the three of them were speechless and nodded repeatedly.

If you don’t think about it, everyone really thinks that their speed is very fast, but if you think about it carefully, you can imagine how slow your speed is.

It took ten hours to walk the journey that Zhang Zichen had taken for three hours, which was indeed very slow.

"Since you all figured it out, we must speed up a little." Zhang Zichen looked serious and did not dare to slack off at all. "I don't know how long this underground undercurrent is. There is no spiritual energy here, and there may be unknown dangers. If I don't speed up, I'm afraid that if it happens."

"What are you afraid of?" Tan Lu swam to Zhang Zichen and blinked and said, "Zhang Zichen, aren't you very powerful? A long time ago, you were able to kill so many powerful Saint Lords at the late stage of the True Lord. If there is danger, you will definitely protect us."

Zhang Zichen smiled bitterly and asked back, "What if we meet monsters above the mid-stage Holy Lord's realm?"

"This..." Tan Lu was speechless.

This is the case. Although Zhang Zichen is very strong, he is at most the same as the strong ones in the early stage of the Holy Lord. If a strong one above the middle stage of the Holy Lord emerges in the middle stage of the Holy Lord, then everyone will definitely die.

Tan Lu was originally a person who was afraid of death, and he suddenly accelerated without waiting for a second.

Seeing this, the rest hurriedly accelerated.

In fact, what Zhang Zichen is not worried about is the monster above the mid-stage Holy Lord's realm, what he is worried about is the true energy in everyone's body.

Although everyone's space ring contains a lot of spiritual source stones and true source stones, as well as many spiritual medicines and immortal medicines, which can be used to absorb spiritual energy and replenish true energy.

However, I don’t know how long this underground undercurrent was. When Zhang Zichen and others were injured, they were trapped in this dark underground undercurrent. I don’t know how long it took.

What would happen if the spirit source stone, true source stone, spiritual medicine and immortal medicine on the big guy's body be absorbed completely before everyone could get out of this underground undercurrent?

Tan Lu and others may not have thought about this, but Zhang Zichen has been worried.

Zhang Zichen didn't want to go back to the closed underground space again. If he didn't rush out this time, then his group of people would be trapped there forever until they die of old age.

Fortunately, at Zhang Zichen's reminder, the speed of everyone has increased several times.

Five people, five rays of light, are like five fish, and are like five meteors, going upstream with extremely fast speed.

...

...

Above the blue water pool.

A second ago, the sun was still scorching in the sky and cloudless, but suddenly, dark clouds covered the sun and strong winds suddenly rose.

Within a radius of five million kilometers, the climate is abnormal and unpredictable.

Boom!

A thunder and heavy rain were overwhelming.

Somewhere in the center of countless ponds and lakes, there is a small lake of thousands of square meters, and above the lake, there is a small mountain of rocks.

This small stone mountain has been around for more than two hundred years, and no one has come close to it.

No one knows the reason.

You should know that most of the cultivators who come here to practice are cultivators in the middle stage of the True Lord and the late stage of the True Lord. This is already a top master.

However, when they wanted to get close to this small stone mountain, they were all bounced away by an invisible rebound force.

No one could enter the area of ​​this small lake, and no one had ever entered the small stone mountain in the middle of the lake.

Why is this, no one can give an answer.
