Twisting the stone plug, completely cut off the overflow of natural power, Feng Yun's expression has become dignified, not only pricked up his ears, but also placed his hands on the stone pipe.

He was sensing the impact of his actions on the stone pipe, and the most important thing was to determine whether the stone pipe would be able to withstand it or not.

After a long period of exploration, Fengyun got the results that made him gratified. Although the force of nature trapped in the stone pipe caused a relatively large pressure on the stone pipe, it was far from reaching its limit. There is no need to worry about it being affected. damage.

Feng Yun let go of the hanging heart, and the person also relaxed, but he did not let himself relax. On the contrary, he immediately turned to face a rock wall and quickly came to its front, at a very fast speed. Cut on it.

What Feng Yun cut from the stone wall was a huge stone.

As soon as the boulder broke away from the rock wall, Fengyun immediately processed it. Soon, it became a stone stopper, almost exactly the same as the stone stopper Fengyun used to control the natural force in the stone pipe not long ago, but it was big. A lot.

His next action was basically the same as when he handled the first stone plug. He opened a hole in the stone pipe that carried the river water, sent it into it, twisted it, and sealed the river water.

Looking around, Feng Yun once again came to the stone wall and cut it against it. This time he cut from the rock wall in regular blocks, and each stone was tall. , Three feet square.

Feng Yun moved very fast, cutting out many stones in a short time, but if you look closely, you will find that their shapes and sizes are exactly the same.

When the stone strips that Fengyun cut from the stone wall were piled up into a mountain, he chose to stop.

He didn't stop working, and as soon as he stopped cutting the stone strips, Feng Yun quickly walked to the opening of the stone pipe carrying the river water, first glanced at it, and then looked around.

After a while, Fengyun Tanshou had taken a stone shovel. This stone shovel was no longer the first one he made. It was already broken.

When choosing the material for making stone shovel, Fengyun made a choice on the stone wall and chose a good stone, but after all, the stone wall is made of ordinary rocks. Choose from them, even if they are good, they still belong to the category of ordinary stones. .

In addition, Fengyun used a stone shovel, and the pressure exerted on it was far from comparable to ordinary people, so even though he had been more careful, he eventually broke down.

Later, Fengyun cut a piece of stone from the stone pillar and made a new stone shovel.

It has not disappointed Fengyun, it has taken a long time, not to mention it is broken, even the signs of wear are not obvious.

Feng Yun grabbed the stone shovel and immediately began to dig. He dug a large hole in the opening of the stone pipe that transports the river water, much larger than a football field, and connected to the stone pipe that transports the force of nature. The core of the man-made double cold springs are all included.

The big hole Fengyun dug this time is different from the one he dug before. Although it is big, the bottom is very flat.

After completing the excavation of the pit, Fengyun began to move the stone strips he had cut from the stone wall. First, he laid a layer on the bottom of the pit, and then built a solid and regular structure around the pit. The stone **** turned the big hole into a pond.

After checking carefully, and thinking about all the details carefully, after confirming that there was no problem, Feng Yun walked up to the stone pipe carrying river water, twisted the stone plug on it, and the stone pipe was restored to flow again. , And suddenly a clear stream of water gushed out.

The river water gushing out of the stone pipes all flowed into the large pond built by Fengyun using strip stones.

Seeing the clear river water flowing continuously into the pool, Feng Yun nodded slightly, seemingly satisfied, but he frowned soon.

The stone pipe is very thick, and with the big funnel welded on the other end of it, the water output is quite large, but the pool built by Fengyun is big and deep, and I want to fill it up. Now, it still takes a lot of time.

After a little hesitation, Fengyun took the stone shovel in the past, and got busy again. He came to the small river and built a dam in the river to restrict the river water so that it would no longer flow downstream and all poured in. In the stone pipe that carries water.

Although the diameter of the stone pipe has not increased, the flow rate of the river water has increased, and the amount of water flowing into the pond per unit time has become more.

"Two hours and sixteen minutes."

This is the time required for Fengyun to activate the ability to collect data, and the resulting pool is filled.

More than two hours is not a long time, but Fengyun is unwilling to waste it. He jumped directly into the pool and came to the core of the man-made double cold spring. It reinforced it to minimize its connection to it. The pressure of the stone pipe.

By the time he was very busy, more than two-thirds of the core of the artificial double cold spring had been submerged in the water.

He thought for a while, took out the treasure knife, and began to cut on the core, and finally he cut nine holes in it.

They are located in different parts of the core, and there are no regularities. Besides, they are all the same size. The larger ones have the size of a bowl, and the smallest ones are struggling to get a finger in.

After checking the nine holes, when he confirmed that a lot of water had been poured into the core, Feng Yun jumped up from the water, jumped onto the stone pipe that conveys the power of nature, and walked to the stone plug. Grab it and twist it.

Feng Yun didn't release it all, only unscrewed it for a little while, even so, the core of the man-made double cold spring changed in a very short time.

Less than 30 seconds have passed since Fengyun twisted the stone plug and released the force of nature. He heard a buzzing sound from the core, the sound was still increasing rapidly, and the loudness increased by more than one between breathing. Times.

At the same time, Feng Yun felt a vibration in the core, which made him immediately nervous, and he was worried that it would be disconnected from the stone pipe.

In order to increase the firmness, although he spent a lot of time connecting the stone tube and the core, there is still a possibility of disconnection if the vibration is too large.

Fortunately, the vibration from the core didn't last long, and soon calmed down, and even the sound from it became smaller.

The declining vibration and sound does not mean that the core changes are over, on the contrary, the real has just begun.

Feng Yun can clearly feel that there is cold air radiating from the core, and as time goes by, the radiating cold air becomes heavier and heavier.

At the same time, he also noticed that there was natural power to gather to the core position. At first, it was relatively small, but the momentum of growth was very rapid.
