Stone strike is a very flexible technique.

A cultivator with low strength can control the ground and accumulate energy to throw it out at any time. It is like a large papaya. A cultivator at the second level of the Qi Refining Stage can condense a stone strike technique that is the size of a normal human head.

If the strength is higher and the cultivation reaches the third level of the Qi Refining Stage, the stones condensed from the land can be larger, just like a person half a body.

The cultivator in front of him, seeing that his cultivation level was only one level of the Qi Refining Stage, he also condensed a stone that was about half a body of one person.

This stone is not a round stone, but a square and regular-looking stone.

Yu Qingyi noticed the strange point and looked even more seriously.

The next scene also surprised him even more.

Because, after he saw the monk condensed a stone and lifted it up about half a person, he threw it directly down.

With a dull sound, the huge rock hit the ground.

Yu Qingyi was even more puzzled. She observed it very carefully. The monk had normal magic power and his behavior was not wrong. It was completely different from a move that was not as powerful as a move that was not as good as a master's ability to do.

Sure enough, the monk drove the huge rock to a height of half a man again.

Then... it fell down again.

The only difference is that the stone moved one step forward, which happened to be the length of the stone.

Seeing this, if Yu Qingyi doesn’t understand what’s going on, she’s too stupid.

That’s right, this monk actually used the magic of cultivating immortals to lay the foundation for road construction!

Moreover, he wasn't alone doing this.

Obviously, he was just the earliest student to arrive.

There are countless students and monks like him, and many others are like this. They use stone strike techniques to lift the stones, then smash them heavily on the ground to tamp the foundation.

"A great immortal cultivator actually became a construction site worker?" Yu Qingyi felt that the world was a bit too crazy.

Even more crazy seems to be still behind.

There were more than a dozen monks who also used stone strike techniques to condense the stones on the ground and then transported them to the cart. One stone strip after another was very regular.

Then, another monk stood in the reservoir, which was comparable to Nian You. Then one magical method was shot out, and it was a magic called Stone Wall technique.

This technique can condense the soil and gravel on the ground together to resist arrows, or swords, guns, swords, and axes.

However, after these dozen monks activated their magic power, they quickly completed the prototype of a reservoir.

Then, the stone strips were paved and a reservoir dam slowly took shape.

What surprised Yu Qingyi was obviously more than that.

The most important thing about a reservoir is obviously that there is a valve mechanism that can store water during floods and drain water during droughts. Therefore, flood discharge outlets and other things are very critical.

Water conservancy facilities like Dujiangyan must be realized by ingenious craftsmanship.

Jishi University does not have such a talent at this time.

Therefore, the reservoir they designed is a reservoir that is honestly storing water and draining water.

As Yu Qingyi became deeper and deeper, the mirror she saw became more and more surprised.

He read that right. More than twenty students, led by a Formation Master in the Foundation Establishment Stage, were constantly setting up array eyes and stabbing into the formation flag.

The spiritual energy between heaven and earth slowly condensed into it, and a wave of spiritual energy that was almost visible to the naked eye appeared in front of Yu Qingyi.

He understood that this was an energy-absorbing device of a large formation.

Not all formations can only rely on spirit stones to satisfy spiritual energy consumption.

Because, the intelligent formation master discovered early on that he could absorb the dissipated spiritual energy from the outside world to fill the formation.

When most formations are not activated, the spiritual energy required is only used to meet daily maintenance needs.

Therefore, they designed various energy-absorbing devices.

Of course, all such formations are extremely expensive, complex in design, and expensive in cost. The most important thing is to have a huge formation area to spread.

Generally speaking, the major forces of various sects and families often use the most, and the so-called mountain guard formations and city guard formations are the same.

Of course, Yu Qingyi has seen this kind of formation.

However, he never expected that he would see this kind of mountain guarding formation again today, which was actually on a reservoir.

At the same time, a cheer sounded at the formation.

Sure enough, a powerful spiritual power valve slowly formed.

This valve blocked the water flow, and the surging river water upstream seemed calm and tame at this moment.

Next, it's just a simple water grinding time.

The complete prototype of a reservoir has been completed, and only some villagers need to continue digging soil and consolidate the reservoir.

After taking Yu Qingyi to read these, Ji Xia did not stop and took Yu Qingyi to continue walking forward.

Not long after, they went to a small mountain village.

After approaching the small mountain village, Ji Xia specially instructed Yu Qingyi to bring a veil on the hat.

"It's not for the purpose of concealing the description, but here is a place to cultivate spiritual insects." Ji Xia explained: "In this world of immortal cultivation, there is a special type of monk who relies on cultivating spiritual insects and beasts to fight. Relying on tens of thousands of flying insects on the city wall, it is very strong in the battle and very troublesome to face."

"But, raising these flying insects is not a trivial matter. First of all, feeding these tens of thousands of flying insects is a big problem. But... this time we came up with a trick." Ji Xia said, walked in and said to a thin and capable man.

"Lao Hong, how is the cultivation of this strong mantis?" Ji Xia asked.

Lao Hong said: "You came here just so coincidentally, I will give you some insights."

After saying that, Lao Hong went out with his urination and dragged a spiritual pet bag in his hand.

The spirit pet bag was very slender and hung around the waist like a belt before it was taken off.

After taking it off, floating in the air, hundreds of things like mantis flew into the air, and then slowly fell into the spiritual pet bag.

At this time, the spirit pet bag had changed from a large cylinder to a rectangle, like a honeycomb, with dense and thin holes inside, and one after another of the big beetles moved into it.

Lao Hong looked around with his eyes, and finally muttered something, and looked at it all the time, looking for the direction.

After passing hundreds of steps in a row, Lao Hong stopped laughing and threw the powerful beetle in his hand into the air.

Soon, these powerful beetles flew into the air densely and landed on a grass in front.

Not long after, these powerful beetles seemed to be no insects, but turned into ground-broken mice. They were covered with green grass and were turned open.

Yu Qingyi didn't want to ask herself, as she seemed to have no vision, so she came over carefully and looked at her carefully.

This time he saw it, he couldn't help but surprise him.

Because, all the locust eggs were excavated on the ground!

Yu Qingyi was surprised. She was so smart that she instantly understood the importance of this place.
