It's just that not seeing the sun or plants will make people live for a long time and produce some depressing feelings.

Tang Yu thought for a while, then continued to extend his spiritual thoughts outwards, directly into the surrounding rock walls. He wanted to see if he could explore the rock walls and find the location of the underground city.

But after exploring in all directions, Tang Yu was shocked to find that even if his spiritual thoughts were extended to the limit, they could not penetrate the rock wall. In other words, if this underground world is really in Gucha Mountain Underground, its location from the surface is at least three to five million kilometers deep.

Is Gucha Mountain really that deep?

Tang Yu is not sure that this is not the earth after all. Tang Yu has experienced too many different cultivation worlds from the earth.

So he couldn't guarantee what the situation here would be like.

But judging from the current situation, what Tsukicheng Sakura said is right. It is quite safe here. It is simply impossible for cultivators in the Dark Evil Land to create a passage to connect to this world.

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

When his spiritual thoughts were extended to the maximum range, he could still see the existence of these crystals, but what made Tang Yu feel puzzled was that these crystals were obviously energy stones, but they did not react at all when swallowing the space.

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

Tang Yu thought for a while and decided to collect some of these stones. He casually used his spiritual thoughts to wrap up a large pile of earth and threw it into the energy space, asking Lotus Hezhu to help collect these crystal stones. Although he did not accurately detect them, Tang Yu estimated that the earth rocks he had casually found There are at least nearly a billion of these crimson crystals in it.

In the rock walls of this world, this kind of crystal can be seen everywhere in the locations that Tang Yu explored. If Tang Yu can use this kind of crystal, he will collect all the crystals here. It can be expected that the crystals here The quantity must be calculated in at least trillions (trillions here are taken as one hundred billion).

What a terrifying number this is. Before, Tang Yu only needed tens of billions of evil demon crystals to improve his cultivation by one star. The number of crimson crystals here is comparable to tens of billions of evil demon crystals. It is much more terrifying. Every time The energy contained in a crystal of the same size is similar to that of the evil demon crystal.

If Tang Yu can absorb it,

He doubted whether he could directly improve his cultivation to the peak of the Nine Realms of True God.

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

"Master, there are already 1.6 billion crystals. These things seem to be of no use!" Soon, the voice of lotus and bamboo sounded in Tang Yu's mind.

"Oh! There are so many, more than I thought!" Tang Yu sighed with emotion, and then said: "It is indeed of no use now, but I don't know if it will be useful in the future. Let's keep it first Keep it! It’s good even as a souvenir. Give it to Guo’er and the others. This thing is much more beautiful than diamonds!”

"Then I will put these energy stones in place." Lotus Hezhu said immediately.

"OK!"

Tang Yu's investigation actually didn't last long, probably only a few minutes. Others had almost fully explored the situation in the underground world.

However, what is certain is that although other people's cultivation is much stronger than Tang Yu, they do not have Tang Yu's powerful spiritual thoughts, so the situation they detect is definitely incomparable to Tang Yu.

"Boss Tang, what do you think of the situation here?" Mr. Xing Chen asked.

"It can be said that it is very good. Except for the lack of green mountains, green waters and white clouds in the sky, in terms of safety, this place is definitely the safest place in the entire ancient temple mountain." Tang Yu said with certainty.

"That's no problem! Lord Yue City, you have really found a suitable place!" Tang Yu praised with a smile, and then said: "You go and pick up the people outside now, I will think of a way now, more Set up some teleportation arrays.”

"good!"

Everyone split up and got busy quickly.

This time, Tang Yu did not choose to set up any large-scale teleportation array. There is a main teleportation array, which is enough for use. Anyway, before the end of the war, the practitioners of Xuehua City will definitely not need to leave here again.

Even if they wanted to leave and join the battle, the other cultivators in Gucha Mountain would probably not agree to their request.

This ancient teleportation array is even more powerful than the large-scale teleportation array arranged by Tang Yu. It can teleport millions of people at once. It is a hundred times more effective than the teleportation array arranged by Tang Yu.

If according to Tang Yu's original statement, the cost of setting up this teleportation array must be several times that of Tang Yu's expenditure on setting up a ten thousand people teleportation array. But in fact, this is not necessary. This teleportation array uses some special and Precious materials, it is the existence of these materials that makes the entire teleportation array not so expensive.

Tang Yu didn't have these materials. He had never encountered such materials in the ancient temple and in so many worlds. Otherwise, he would definitely not choose to arrange a teleportation array for 10,000 people, and he would directly launch this teleportation array, which can be said to have few restrictions.

When Tang Yu arranged the teleportation array, he deliberately avoided the sight of other people, because he didn't know who the traitors of their ancient temple mountain were.

Although these people were deliberately selected by Grandpa Xingchen, it would be very difficult to find people who were parasitized by the practitioners of the Black Evil Land if the other party did not actively expose themselves.

More and more people appeared in this underground world.

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

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

In front of everyone, after quickly setting up several simple teleportation arrays at several locations in the valley, Tang Yu entered the underground world again and said to Yue Chengying: "City Lord Yue, everything here is left to you. I must leave now and go to more places to set up teleportation arrays, otherwise the problems that Mr. Xingchen is worried about will really appear, which will be troublesome!"

"It's okay, leave it to me here! I promise that as long as the materials are sufficient, there will be a steady stream of magic-modified cannons, which will be transported out from here." Yue Chengying said firmly.

"Well! Be safe!"

"Help our practitioners in Xuehua City to kill more beasts in the Black Evil Land." Yue Chengying shouted at Tang Yu's departing back.

"Definitely!"

Tang Yu raised his hand without looking back, waved it twice, and left this underground world with Ye Yunlan and others.

Tang Yu left, but Mr. Xingchen and Ye Yunlan and others might not leave. For safety, Tang Yu even left Xia Tangming and others who could also refine weapons here.
