When Lin Yuan observed the little squirrel, Hu Quan had already checked the surroundings.

Hu Quan said in surprise.

"Young master, all the trees around this place are ironwood. ”

"When crushed, the ironwood is much better than metal chips. ”

"Ironwood is sticky, and mixing it in sand gives it the flexibility and malleability of metal. “

"The landscape here is a forest, and there must be water deep underground. ”

"Ironwood chips mixed with sand and gravel are laid on the outermost layer of the underground palace, which can effectively play a role in retaining water. ”

"And ironwood will not be rusted and corroded by moisture for a long time like metal spiritual wood. ”

Hu Quan said this, and Lin Yuan immediately shook his sleeves.

The amber button-shaped source sand fell directly to the ground, turning into sand and burrowing into the ground at Lin Yuan's feet.

At this time, the source sand was no longer a spiritual creature of the gold-level fantasy species.

The current Source Sand has been raised by Lin Yuan to the level of the Diamond Rank Level 1 Fantasy Second Transformation.

Therefore, the current source sand wants to change the underground environment, but it is as simple as hand-to-hand.

Sand production is the most basic ability of source sand.

Soon, the guard sand was wrapped in a large amount of sand grains, and like a giant dragon, the land under Lin Yuan's feet was crisscrossed and horizontal.

With the portal formed by the space corridor as the center, the surrounding sand and gravel ten meters below the ground are quickly crushed.

At the same time, the source sand also strips the roots of those ironwood from the sand and gravel.

The sand flow is criss-crossed, and the two kilometers of ironwood within the radius are completely gathered together.

These ironwood were all materials that Hu Quan needed to build the underground palace next.

While Lin Yuan was changing the environment of the land under his feet, Liu Jie also asked ten hurricane armyworms to detect in ten directions.

Liu Jie felt the picture seen by the ten Hurricane Armyworms through the spiritual power connected to the insect mother.

Immediately, Liu Jie took out a piece of paper and a pen from his diamond level trapped spirit box, and simply mapped the surrounding map.

In the process of directing Yuansha to transform the underground environment, Lin Yuan also made Yuansha transform the ground environment.

However, Lin Yuan's transformation of the ground environment is only one meter thick on the surface.

The remaining nine meters are still mud mixed with sand and gravel.

As soon as I got busy, the time passed a full four hours unconsciously.

Lin Yuan released Xiao Hei during the period, and asked Xiao Hei to cast a spirit on himself and Liu Jie every few minutes.

Xiao Hei is now also a Diamond-level fantasy spirit creature.

Therefore, even if Lin Yuan so vigorously urged the source sand to change the landform, the aura would always remain in a half-full state.

A two-kilometer radius of surface and underground landforms has been transformed.

Lin Yuan's transformation of the surface is also very meticulous.

Because the right surface transformation is related to the progress of Yinhua giving birth to the white bone lotus on the surface in the future.

The white bone lotus flower is undoubtedly much more convenient to move in the sand than in the wet and clay soil.

The White Bone Lotus is essentially a derivative of Yinhua, which feeds on the soul.

There is no need to get nutrients from the soil at all.

Lin Yuan, who had been working for four hours in a row, had always maintained sufficient spiritual power in his body.

However, Lin Yuan, who had been transforming the surface and underground landforms for four hours, still felt very tired.

Lin Yuan said to Hu Quan, who was making a metal frame with five spirit craftsmen on the side.

"Uncle Hu, you can now go underground to build the framework of the underground palace. ”

"You're working hard during this time, so you have to build the framework as soon as possible. ”

"Otherwise, if there are a few heavy rains and the water seeps into the ground and the ground gets wet, it will be very dirty and troublesome for you to do your work again. “

After speaking, Lin Yuan saw Feng Shuang, who was standing behind him and didn't dare to speak out, Lao He and Hu Tian said.

"You three are going to help, too. ”

"In the process of building the underground palace framework, Hu Tian, your spiritual objects can play a big role. ”

"Feng Shuang, Lao He, although the spiritual objects of the two of you are not very useful, you can also fight and exert some strength. ”

Hearing Lin Yuan's words, Feng Shuang, Lao He, and Hu Tian were directly shocked.

From the conversation between Lin Yuan and the others just now, the three of them knew that they and the others were in the Shenmu Federation at this time.

Although the three of them are four-star founders, they have a good vision.

But in the cognition of the three of them, if they want to cross the Federation, there is generally only the island whale.

But obviously, Lin Yuan didn't come to the Shenmu Federation through the Island Whale.

This made the three of them feel that Lin Yuan had become more mysterious.

Moreover, Feng Shuang recognized Liu Jie's identity when Liu Jie had just entered the treasure cave golden toad treasure.

Hu Tian and Lao He also recognized Liu Jie after Liu Jie summoned the worm mother.

The three of them were secretly speculating in their hearts, could it be that Liu Jie, a member of the Radiant Hundred Sons Sequence, had also joined Sky City.

Is it a member of the city in the sky?

The three of them were in shock, and their minds were running rapidly.

The three of them have been thinking about how to talk to Lin Yuan and show themselves.

When he arrived in a new environment, Lin Yuan didn't bring the founders over, but only brought six spirit craftsmen.

All three thought they were about to be reused.

However, now Lin Yuan not only did not reuse himself and the others, but also let the three of them go to the spirit craftsman.

This made the three of them wonder for the first time in their hearts whether the founder is a noble profession at all.

However, even if the three of them were unwilling to give a hand to the spirit craftsman in their hearts, they had to carry it out under Lin Yuan's order.

Hu Tian, who thought that he had the best relationship with Lin Yuan and was most valued by Lin Yuan, asked carefully.

"Master, will we escape here from now on?"

Lin Yuan shook his head when he heard this.

"This is not the place for the three of you to escape. ”

"The three of you have a crooked mind, and first do a good job of the work that is assigned to you in front of you. ”

"After arriving at the place of escape, these tasks need to be done at the moment. ”

"I don't have a shortage of builders here. ”

"Although the three of you are four-star builders, it would be more useful for me to do some chores than anything else now. ”

Hearing Lin Yuan's words, Hu Tian, Feng Shuang, and Lao He were completely dumbfounded.

The three of them completely understood, and Lin Yuan didn't take his identity as a four-star creator seriously at all.

How many Founder resources does this Sky City have?

Lin Yuan was willing to let the three of them not mix the spiritual liquid, but to do hard labor here.

Feng Shuang gritted his teeth and summoned his Lu Xing Emperor Crocodile.

Let Lu Xingdi Crocodile take the initiative to transport the metal shelves that Hu Quan and the others had just erected within four hours to the ground.

Seeing Feng Shuang's first action, Lin Yuan spoke.

"Feng Shuang, you did a good job. ”

"As a reward, after your spiritual object is promoted, whether you want to survive the baptism of heaven and earth or the catastrophe of creation, I will send someone to help you get through it safely. ”

As he spoke, Lin Yuan threw five earth-attribute celestial-grade elemental pearls to Feng Shuang, which could be regarded as a reward for Feng Shuang.
