It’s just that the light of day and plants are gone, and people will make people live for a long time and feel some depression.

Tang Yu thought for a while, continued to extend his divine thoughts outward and directly penetrated into the surrounding rock walls. He wanted to see if he could find out the rock wall and find the location of this underground city.

However, after exploring all directions, Tang Yu was shocked to find that even if his divine consciousness extended to its limit, it could not seep out of the rock wall. In other words, if this underground world was really underground in Gusha Mountain, its location was at least 300,000 to 500,000 kilometers deep.

Is there really such a deep place in Gusha Mountain?

Tang Yu was not sure. After all, this place was not the earth. Tang Yu had experienced too many cultivation worlds, which were different from the earth.

So he could not guarantee what the situation here was like.

But judging from the current situation, Yue Chengying is saying it is quite safe. It is impossible for practitioners from the Black Evil Land to create a channel to connect the world.

While exploring the situation, Tang Yu was also attracted by the large number of red crystals present in the rock wall.

When his divine consciousness extended to the maximum range, he could still see the existence of these crystals. What made Tang Yu feel confused was that these crystals were obviously also an energy stone, but there was no reaction at all in the devouring space.

He didn't know what kind of energy stone this crystal belonged to. He tried to study the other party. Although he could find the energy contained in the stone, it did not stir up the energy inside. They were like arrogant little princesses, completely ignoring Tang Yu's temptation.

Tang Yu thought about it and decided to collect some of this kind of stones. He casually used his divine thoughts to wrap a lot of earth and threw it into the energy space, asking Lotus Lotus and Lotus Bamboo to help collect these crystals. Although it was not accurately detected, Tang Yu estimated that the earth and rocks he made casually contained at least one billion of these red crystals.

In the rock walls of this world, this crystal can be seen everywhere where Tang Yu discovered. If Tang Yu could use this crystal, he collected all the crystals here. It can be expected that the number of crystals here would be calculated in at least trillions (the ones here are taken as one billions).

What a terrifying number this is. Tang Yu only needed hundreds of billions of evil demon crystals to improve his cultivation level by one star. The number of red crystals here is much more terrifying than tens of billions of evil demon crystals. Each crystal of the same size contains similar energy as the evil demon crystals.

If Tang Yu could absorb it, he doubted whether he could directly raise his cultivation to the peak of the Ninth Realm of True God.

However, after thinking about it, Tang Yu couldn't help but smile bitterly, because if he really absorbed all so many energy crystals in one breath, there would be only one outcome, that is, his body was directly burst by the energy contained in so many energy crystals.

"Master, there are already 1.6 billion crystals. These things seem to be useless!" Soon, the sound of lotus flowers and lotus bamboos sounded in Tang Yu's mind.

"Oh! There are so many, more than I thought!" Tang Yu sighed, and then said, "It's really useless now, but I don't know if it will be useful in the future. Keep it first! Even if it's used as a souvenir, it's good. I'll give it to Guoer and the others when I go back. This thing is much more beautiful than diamonds!"

"Then I will put these energy stones into place." Lotus Lotus Zhu said immediately.

"OK!"

Tang Yu's exploration did not last long, and it only took a few minutes. The others had almost explored the situation in this underground world clearly.

However, it is certain that although the other people's cultivation is much stronger than Tang Yu, they do not have the powerful divine consciousness like Tang Yu, so the situation they found is definitely not comparable to Tang Yu.

"Boy Tang, what do you think is going on here?" Old Master Xingchen asked.

"It can be said that it is very good. In addition to the lack of green mountains and clear waters, the sky and white clouds, in terms of safety, this place is definitely the safest place among the entire ancient temple mountains." Tang Yu said affirmatively.

"Then there is no problem! Lord Yue City, you really found a suitable place!" Tang Yu smiled and praised, and then said, "You go and pick up people outside now. I'll find a way to arrange more teleportation arrays."

"good!"

Everyone acted separately and became busy quickly.

This time, Tang Yu did not choose to arrange any large-scale teleportation array. There is a main teleportation array, which is enough to be used. Anyway, before the end of the war, the cultivators in Xuehua City will definitely not need to leave here again.

Even if they want to leave and join the battle, the other cultivators in Gusha Mountain probably won't agree to their request.

This ancient teleportation array is even more powerful than the large teleportation array arranged by Tang Yu. There is no problem with teleportation of millions of people at one time, and it is a hundred times the effect of the teleportation array arranged by Tang Yu.

If Tang Yu said in the original opinion, the cost of this teleportation array was to be arranged by Tang Yu to arrange a teleportation array of 10,000 people, but in fact, this does not need to be done. This teleportation array uses some special and precious materials. It is the existence of these materials that makes the entire teleportation array not so much.

Tang Yu did not have these materials. He had never encountered such materials in the ancient temple after experiencing so many worlds. Otherwise, he would not have chosen to arrange a teleportation array for ten thousand people, and he would have just started to go on horseback. This kind of teleportation array that can almost be said to be without many restrictions.

When Tang Yu set up the teleportation array, he deliberately avoided the other people's sight because he didn't know who was the traitor of their Gusha Mountain.

Although these people were deliberately chosen by Mr. Xingchen, if the other party did not reveal the situation on his own initiative, it would be very difficult to find someone parasitized by the cultivators of the Black Evil Land.

More and more people appear in this underground world.

All the people who had just arrived in this underground world were shocked by the magnificence here, but soon all the practitioners of Xuehua City chose some suitable locations and began to refine magic-modified cannons.

Tang Yu spent nearly an hour to finish some of the situations in this underground world, and then sat in the teleportation array, left the underground world, and returned to the ancient temple mountain.

In front of everyone, after quickly setting up a few simple teleportation arrays in several locations in the valley, Tang Yu entered the underground world and said to Yuechengying: "Lord Yuecheng, everything here is left to you. I must leave now and go to more places to arrange teleportation arrays, otherwise the problems that Mr. Xingchen is worried about will be troublesome!"

"It's okay, leave it to me here! I promise that as long as there are enough materials, there will be a continuous stream of magic-modified cannons to be transported from us." Yuechengying said firmly.

"Yeah! Be careful!"

"Help us Xuehua City practitioners kill more beasts from the Black Evil Land." Yue Chengying shouted to Tang Yu's departure back.

"must!"

Tang Yu didn't look back, raised his hand, waved it twice, and left the underground world with Ye Yunlan and others.
Chapter completed!
