That's right, this is a protracted war, it is Si Fan's protracted war in the face of nature, in the face of the desert, there is no victor in this war, only the great force of nature, in front of Si Fan is endless yellow sand constantly from the ground to try to dig Si Fan out of the old paper pile of history, this is the encroachment of the desert death.

Si Fan persevered in this ruthless wind and sand for three days, in the first two days, it was still very comfortable, Si Fan could spare a few hours of rest every day, as long as the ultra-high gravity geological transformation instrument was turned on, then there was no problem, but when the third day came, the accident finally appeared.

He looked up at the wind and sand outside under the underground sinkhole, and the sand control net on the upper layer played a loyal role, rejecting all the sand and dust outside the sinkhole, and the T739 Terminator inside was constantly busy, opening up the space above, and then constantly gluing the sand layer outside.

Si Fan even used all his strength to strengthen the sand and dust, and used strong gravity to forcibly change the environment of these sandy places, so that they entered a rock-like state, and after a strong backlog of sand, it became sticky, and all the sand seemed to be mixed together, which was the effect of super gravity.

In the past, Si Fan was all about transforming the geology, all of which were used to compress the ground soil, and all of them were evenly distributed by force. But this time it was different, Si Fan applied all his power to the limited sand layer of the sand layer, and then applied pressure up and down, exerting a lot of pressure. It is only a small area that is modified, so that the gravitational force increases dramatically.

With such additions, the sinkhole above seems to be getting stronger and stronger.

But on the third day, an accident occurred, and just as he was desperately trying to reinforce all the inner walls of the sinkhole, suddenly puffs of sand and dust seemed to blow in from the outside.

This made Si Fan stunned, he continued to strengthen the sand layer below for three days, but there was no wind and sand coming in above, but now, it was completely different, Si Fan felt a large amount of wind pouring here, and then saw a shocking scene, the dust net pressed by countless concrete above was now constantly invaded by the wind, and the concrete seemed to be undergoing the baptism of the wind, and it didn't take long for it to be torn apart.

This high-strength dust filter itself has a strong resistance to wind and sand, but it can be easily damaged when there is a gap.

This is exactly what is happening now. What made Si Fan even more frightened was that because the wind was bearing under the dust net, the entire dust net was lifted up in an instant under the circumstance of a ride.

You must know that this is a dust filter, which itself is ventilated, just to reduce the force, but it is useless now.

At this time, Si Fan's last protective shield was gone, he emerged from the wind, and then he felt the ruthlessness of nature, and the wind poured in, making it almost unbearable for Si Fan to bear, and the surroundings became a yellow world in an instant.

Countless pieces of yellow sand were blown in.

At this moment, Si Fan even felt as if he was about to be torn apart, so he stopped all the transformations, put all the gravitational pull on his side, and then the power went down.

This is Si Fan's way of coping.

Sure enough, when the gravitational force was all confined to Si Fan's side, the yellow sand was attracted to the bottom by the strong gravitational force, and then fell into the water, Si Fan also gave an order in mid-air to let the terminator move him away from the sinkhole, otherwise he estimated that it would not take long to be wasted.

It wasn't a coward to dodge, so Si Fan turned a corner and reached the upper reaches of the river, among the many stalactites.

At this time, the wind blows, and the underground river is constantly dyed yellow, and then it seems to want to fill the entire cave.

Faced with such a situation, Si Fan gritted his teeth and looked at the terminator beside him.

"Is the water in the upper reaches ready, and how is the river cleaning up downstream?" Si Fan asked the Terminators, in the past three days, Si Fan asked all the Terminators to clean up the river and choose the location of the river water upstream.

The system replied, "Report the host, everything is ready." ”

The answer was clean and neat, and Si Fan saw that a large amount of yellow sand landed on the surface of the water, making the river turn yellow, but the river was undulating, bringing the yellow sand downstream.

However, at this time, the river water is yellow, and then the yellow sand finally has downward force, and after moving forward for tens of meters or hundreds of meters, the yellow sand has begun to precipitate.

In such a situation, the means used by Si Fan is to store water in the upstream stage, and then a one-time large-scale water impact.

This is a method of water control from ancient times to the present, and it is very effective to wash the river after the water in the upper reaches of the Yellow River, and Huaxia has persisted in this method for thousands of years.

History has proved that it is still very useful, and Si Fan has already begun to accurately control the gravitational force at this time, so that the wind will fall with the yellow sand like a pepper surface, and then control the force to produce a repulsive force, pushing the yellow sand out of the sinkhole in reverse.

After the two means, the entire Huangsha treatment has already had a little effect.

And Si Fan himself seems to be tired of constantly providing gravity and adjusting the direction of gravity.

The whole process was hard.

And this time is very long, and the requirements for Si Fan are also to pay attention, ensure the control of details, and never let the yellow sand fall into the water in large quantities at one time.

Otherwise, it will be deposited quickly.

Faced with such a situation, Si Fan can be said to be exhausted, and all the terminators have also begun to devote themselves to the cleaning of the yellow sand downstream, they are responsible for exploring the area that needs to be cleaned, and then recording it, and then waiting for Si Fan to come over to help compact all the yellow sand on the ground.

There are more and more such situations, and they are becoming more and more exhausting for Si Fan.

Time is also in a second of the past, the whole underground cave, the entire underground river in such a state, is also combing, all the cave walls began to widen, and then some of the easy to get obstructive rocks below to break or clean up, such a process is very long, the stalactites above the head Si Fan did not move, but the underwater stones are cleaned up a lot, and then widen the road, which is already a must to do, and then build a temporary water storage device in the place where the water flow is gentle, so that the road is temporarily stored, and then directly wash the river.

It seems to have become a daily routine. It's just that Si Fan's energy may not be able to persevere, but in such an environment, Si Fan has persisted until the seventh day, dealing with the river for a short time, and is also using the ultra-high gravitational geological modification instrument to continuously transform the river, when the seventh day comes, I'm afraid no one can recognize this person as the world's top rich.
