Several days have passed since the opening of Yunmeng College.

But Li Yu's final preaching on martial arts practice has spread more and more widely over time.

Even the content of the preaching that day was handwritten and kept circulating and copied.

When the outside world was noisy because of the incident, Li Yu had no idea about it.

Worry-free Cave Heaven!

Li Yu named the cave heaven from Hou's family "Wuyou" to commemorate the first force Wuyou Villa, which was founded.

"The cave heaven was destroyed too much by the Hou family, and there was a strange force remaining in the land and air. It must be cleaned up and rectified again."

In the void, Li Yu stood in the air.

His eyes opened between his eyebrows and heavenly eyes, overlooking the earth below.

I saw black auras spread like spider webs throughout the void of the earth. The black aura emitted a special aura, which made Li Yu very disgusted.

This power comes from the Hou bloodline, but the real source is the bronze bell sealed by Li Yu.

Fortunately, although these powers are strange, they belong to the rootless duckweed.

Li Yu refined the origin of the cave and had the heavenly eyes in his hand, so he could clean it up just by spending time.

After a few days, he stayed asleep and kept clearing the remaining strength.

After completely clearing the remaining poisons, Li Yu began to transform the cave.

Fill in the cracked earth, remove the peaks that are in trouble, lead out the groundwater flow, and form a river on the surface.

"Huh! It's finally done!"

At high altitude, Li Yu looked down at the earth below.

Wuyou Cave Heaven has a total of 380,000 square kilometers, which is comparable to the size of a state.

The largest cave heaven after Li Yu was transformed by Li Yu was the plain, which was about 200,000 square kilometers.

The second is the mountains, with an area of ​​100,000 square kilometers, and the second is the sea, desert and swamps.

The vast plain is endless, and the mountains south of the plain are rolling and rolling like a giant dragon crawling.

Several rivers flow out from the mountains and eventually converge into a large river at the mouth of the plain and run through the plain.

The river divides many branches in the middle and lower flows, flowing through the entire plain.

To the west of the plain, there are yellow sands everywhere, with sand dunes standing in the sky; to the north, there are towering ancient trees; to the east, the ocean is boundless.

According to Li Yu's idea, Wuyou Cave Heaven will become an all-round cave heaven that integrates cultivation, food, spiritual medicine and scientific research.

The plains can grow food on a large scale, so there is no need to worry about climate issues at all.

Various kinds of spiritual medicines can also be planted in mountains, deserts and swamps.

"Now everything is ready, but the only thing that's missing is plenty of spiritual energy."

Wuyou Cave Heaven has experienced several major wars, but its origin is damaged and it is no longer possible to generate spiritual energy on its own.

Li Yu has not yet found a way to make up for the origin, but he also has his own way to increase the concentration of spiritual energy.

His right hand was spread out, his eyes were slightly closed, and he focused...

When he opened his eyes again, a blue seed appeared in his palm.

Tianyuan Spirit Tree!

Fourth-grade spiritual roots!

This is the gift that Li Yu received after helping the way of heaven.

The Tianyuan Spirit Tree is a fourth-grade spiritual root, and has a powerful effect of creating spiritual energy and enhancing insight.

Since Li Yu got it, he wanted to use it several times, but he repeatedly put it aside for various reasons.

Until this time I got Wuyou Cave Heaven, I could use it.

"With the Tianyuan Spirit Tree, the Cave Heaven can generate spiritual energy by itself. In addition, the increasingly rich spiritual energy in China, the concentration of spiritual energy in the Cave Heaven will never be high outside."

Li Yu threw out the spiritual seed in his palm, and the latter fell into the center of the cave heaven and above the plain.

As the spirit seeds land, they quickly take root and sprout, and after a few breaths, they have grown to the normal size of a sapling.

At this time, the Tianyuan Spirit Tree exuded a strong suction force, sucking away all the surrounding spiritual energy.

The huge movement created several spiritual storms around.

The Tianyuan Spirit Tree is also growing rapidly at a speed visible to the naked eye, and its height has exceeded two meters in a blink of an eye!

"With the absorption speed of the Tianyuan Spirit Tree, the spiritual energy in the cave is still not enough, and the growth rate is too slow!"

Li Yu carefully sensed it and found the problem.

After he pondered a little, he opened the Cave Heaven Pass near the Tianyuan Spirit Tree and led the spiritual energy of the Shenzhou.

With his actions, the growth rate of the spirit tree increased again.

Seeing this, although Li Yu was still a little dissatisfied, he had no other way.

In order to ensure that there is no problem with the growth of the spirit tree, he has always been guarding him.

Half a month later, the height of the Tianyuan Spirit Tree has exceeded fifty meters and the diameter of the trunk exceeds ten meters, and it has truly grown into a towering tree!

At this time, the spiritual energy produced by the Tianyuan Spirit Tree is enough to be proportional to its own absorption.

Li Yu also closed the channels of the two realms, allowing the spiritual energy to continuously nourish the entire cave.

"The problem of spiritual energy has been solved, so people can come in!"

Li Yu looked at the prosperous cave world with a look of satisfaction on his face.

He returned to Shenzhou and first went to meet the princess. After two days of indulgence, he summoned Song Yuan and other important officials of the domineering palace.

In the Wenwu Pavilion, Li Yu sat in the main seat, and Song Yuan, Xu Lin and others were all there on both sides below.

Because it was close to the end of the year, Li Yu did not let Xu Lin go back, and generals such as Yue Feng, Yu Zhen, Zheng Yuanhao also returned one after another.

"I summon you today, and there is something to be announced."

Li Yu looked calm, glanced at everyone and said, "The transformation of Wuyou Cave Heaven has ended, and you can send someone to settle in."

Below, everyone's faces were filled with joy when they heard this.

"Congratulations to the King, congratulations to the King, with Wuyou Cave Heaven, the forces of the Ba Mansion will surely reach another level!"

Song Yuan stood up and walked out, and saluted excitedly.

The others hurriedly followed and congratulated each other in unison.

"This is indeed a happy event. I will accept your congratulations and get up."

Li Yu waved his hand gently, and when everyone got up, he said, "Now you will go to the cave with Gu to see it."

After saying that, he brought people to the yard, and then connected to the origin of the cave heaven and opened the tunnel passage.

Wuyou Cave Heaven is attached to the Shenzhou Realm. As long as Li Yu wants, he can open the passage at any place to enter.

In the empty courtyard, a blue passage appeared.

Li Yu took one step and entered, and Song Yuan and others followed closely behind.

"What a rich spiritual energy!"

When Tieshan entered the cave and stood on the grass, he felt his body exuding a cheerful and excited mood.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! He sensed it carefully, and his face showed a look of shock.

"The spiritual energy here is indeed rich, and it is probably several times higher than that of the outside world!"

Xu Lin also noticed something strange and said in shock.

"The king, Bei Zhi had also come to the cave world before, but at that time the spiritual energy in the cave world was comparable to that of the outside world, and was even slightly worse. Why did it become like this?"

Li Yan came to Li Yu and bowed his hands and said in confusion.

Tieshan nodded in agreement. He was also present at the time and did not find any difference in the spiritual energy of the cave heaven.

"Haha! You guys come with me."

Li Yu smiled, waved his sleeves and everyone's eyes suddenly turned dark, and they returned to light again, and found that they had come under a big tree.

"What a magical tree!"

Everyone looked up and looked at the big tree in front of them, and suddenly exclaimed.

I saw a big tree towering into the clouds, the leaves looked like spindles, and the whole body was green and emitting soft light. It was transparent like ice water in the sun, like the best jade glass.

Countless blue light spots float around the spirit tree, and the dreamy and magnificent scene is amazing.

The most important thing is that everyone stood under the spirit tree, and the pleasure of breathing in their entire pores was simply intoxicating and reluctant to leave.

"The spiritual energy here is much richer than before, and it seems to be emitted by the big tree in front of you?!"

Tieshan has the highest cultivation level and looks surprised.
