Li Yizheng was walking, suddenly stopped, and said: "If the content of the mural is true, then there is another explanation!"

The fat man and Phantom Ji stopped and looked at Li Yi, who said, "It is very likely that this is the ancient humans before us!"

There is a reason why Li Yi said this, he turned on the super pupil perspective ability, and all he saw was a piece of darkness, so he decided that all these in front of him belonged to prehistoric civilization. Pen, fun, and www.biquge.info

The three of them continued to walk along the stone steps, and the space in front of them gradually became larger and larger, and a huge sarcophagus appeared not far away, and a large number of exquisite murals were carved on the surrounding stone walls.

Looking at these murals in front of them, there were a lot of conquest aspects this time, looking at these murals, Li Yi and the three of them were more sure of their previous judgment.

At the beginning, Li Yi was wrong to think that the Xiongnu destroyed the ancient city on the mural, and in fact a large-scale war broke out in the era of the existence of this ancient city.

The ancient city was defeated and forced to evacuate, and it is impossible to verify where they evacuated. When Li Yizheng was watching with relish, suddenly there was a fluctuation from the ground, and the fat man hurriedly shouted:

"Let's go, there's an earthquake!"

Li Yi, Phantom Ji, and the fat man stumbled out of the underground ancient city ruins, and the vibration from the ground became more and more violent, and when they returned to the ground, the wind suddenly rose, and the sudden sandstorm quickly made everything around them unclear.

The ground was full of people running around, but fortunately, Shao Wu, Wu Tianyi, and Commander He took appropriate measures to cause no casualties. As the wind became more and more violent, everyone had no choice but to hide in prison for safety.

The weather in the desert was unpredictable, and it wasn't until three days later that the unusual weather subsided, and a whole week of bad weather passed. The fat man looked at Li Yi, who was frowning, and asked:

"Ask, Ayi, what's wrong with you? Is it because of the underground ancient city?"

Li Yi looked at the clouds in the sky and said, "It's good that the underground ancient city has disappeared, originally I thought that I would be able to find the whereabouts of Yang Guifei and unlock the secrets in that magical little bowl, it seems that it will take a lot of effort to find them!"

Perhaps God is playing tricks on everyone, the mysterious underground ancient city was buried under the thick sand dunes again with a sudden earthquake and sandstorm, and in the center of the great desert more than 130 kilometers away from here, another ancient city has reappeared.

In the midst of this recent scene, no one dared to venture to it, even though it had been several days since the news of the appearance of the ancient city. Li Yi and the others waited for more than half a month, during which Wu Tianyi exterminated two groups of illegal armed personnel pretending to be businessmen.

On this day, Wu Wan finally arrived at the prison again with the transport plane, this time, Wu Wan and her team conducted a detailed survey of the entire Xinjiang and Tibet regions in the form of transport planes and drones, especially the discovery of a large number of mineral deposits.

"Dr. Wu, let's meet again!"

Compared with nearly a month ago, Wu Wan has not changed much, but Li Yi and the others have all been tortured by the desert climate. Due to the influx of too many people at once, there was an extreme shortage of water around the prison, and the original wells could not solve the drinking water problem of so many people.

"Captain Li, you look really embarrassed, let's make a deal!"

"What deal?" Li Yi couldn't help but be a little surprised.

"You pay, I will dig a deep well here, enough to solve the drinking water of tens of thousands of people around!"

"Really?" Li Yi wondered if he had misheard.

Looking at the barren land around him, Li Yi stared at Wu Wan's beautiful face, if Wu Wan didn't joke, in a few years, there would be an oasis here.

"I'm not kidding, the recent earthquake has damaged the underground river here, and it was difficult for us to use the depth of the underground river, but now we can use the diversioned underground river!" Wu Wan explained.

"You mean to use the underground river as the water source, so how much does it cost to invest in a large water plant?" asked Li Yi.

"It's not much, hundreds of millions!" Wu Wan said casually.

"How long will it take to build it?" asked Li Yi very seriously.

"The first phase of the project can be completed within a year, and if you want the water plant to have a stable water source, you must protect the water source, which will take at least three years and double the investment!"

"Money is not a problem, as long as it can be built!"

The place where Li Yi and his team are currently located is just north of the junction of Xinjiang and Western Xinjiang, and there are many people who live, do business, and travel in this area.

Further east, the source of China's mother river, the Yellow River, has been reduced in water due to the severe destruction of vegetation in the headwaters of the Yellow River in recent years, and the ultimate goal of Wu Wan's plan is to restore the local ecosystem, which will require a large investment.

In the days when Wu Wan left, she learned through a friend that Li Yi was currently the richest person in China, so she planned to cooperate with Li Yi to realize her wish for the fulfillment of all these years.

Wu Wan's wish came from one of her late elders, who had been engaged in geological exploration in Xinjiang since her grandfather, and her father and uncle had both worked in the frontier for many years.

Her uncle, Wu Qing, was working to protect the Yellow River's water source when he encountered poaching criminals and died protecting the local wildlife. Wu Wan knew that she had liked her uncle very much since she was a child, and her greatest wish was to restore the ecology of the Yellow River water source.

After Li Yi learned all this from Wu Wan's mouth, he immediately nodded in agreement with Wu Wan's plan, of course, to realize this plan, the premise is that he must have money, a lot of money.

"Dr. Wu, before we implement this plan, we need to find out if your current plan is feasible!"

"Are you really willing to invest?"

This time it was Wu Wan's turn to be surprised, Li Yi took a deep breath and said: "My plan to find a piece of historical truth has run aground, and before there are no new clues, I can only return to my business, and now that we have decided to cooperate, as long as your plan does not conflict with mine, helping you is equivalent to helping myself!"

"Why do you want to invest so much money in environmental protection?" Wu Wan asked.

"When I was in Australia, I met a few friends, and they were engaged in the breeding business that I think can be used in China, but there are not enough places to do this business in coastal and other areas, and the north and northwest regions are not ideal because of environmental degradation, so your plan is definitely a long-term plan worth investing in!"

Wu Wan didn't expect that someone was really willing to help her, and she couldn't help crying with joy, Li Yi hurriedly comforted her:

"Speaking from the heart, I admire you people with ideals, once I also had my own ideals, for a while I used to think I had forgotten, but now seeing you, I have confidence again!"
