Bringing System to Great Tang

"Yes, the mineral content meets drinking and irrigation standards, not weakly alkaline water."

Li Yi's test results came out when a new batch of Yulin Feiqi went down to investigate.

It is not a weak base, but a weak base is suitable for watering acidic soils.

People have a lot of stomach acid, and drinking a weak base can neutralize it.

But there is another saying that weakly alkaline water is suitable for bacteria to multiply, so if the bacteria content in the water exceeds the standard, you can't drink it.

The water is now neutral, so you can do anything.

There is indeed geothermal heat, and some of the minerals in it are high.

Use it for drinking, not hard water.

"The local large-scale breeding of livestock and poultry should be carried out, and the water in the underground lake should be drunk."

Li Yi also considered large-scale local farming.

There are many trace elements in mineral water, which is good for animals' health. Some pigs lack things and can chew on bricks.

Large domestic geese generally do not eat fish and shrimps, and occasionally eat small ones.

"Another big fish." Cheers came from Li Yi's car.

Li Dan looked at the screen connected to the underwater camera, and saw a **** fish being killed by Yulin Feiqi under the light.

There are many other fish around, coming to the light.

"The underwater temperature is high, and then..."

Li Yi thought about what the fish would eat, and suddenly he was stunned.

He got into the car and said to Yu Lin Feiqi, who was wearing a camera, "Turn off the light, and then turn it on after 20 breaths."

This person made a gesture, and the others turned off the wait with him.

The moment the light went out, a faint light appeared in the picture.

"Treasure land!" Li Yi thought of a science fiction novel. As long as the wait is closed, the surrounding stones will glow.

Looking at the light now is not caused by the stone, but refracted from elsewhere.

"Go find the source of the light, no, first bring the fish up and replace the oxygen cylinder." Li Yi first thought about eating.

This fish looks two meters long. It is not easy for the **** fish to grow so big.

It is said that some **** fish can stay on land for a while, and then be in the water like a crocodile. When they see an animal going to drink, they twist ashore to eat.

Anyway, Li Yi hasn't seen it, it is theoretically possible.

Another big fish was brought up, and the diver changed the oxygen cylinder and went down again.

The common people looked at it one after another, but it was a pity that they didn't have a mobile phone, otherwise they would definitely take pictures and post them in circles.

The diver went down again, looking for the source of the light. For about twenty minutes, when he was about to return, the light in front suddenly became bright.

The Yulin Fei rides swam past the light, and when the light turned on, a dazzling golden light appeared.

"Gold?" Li Dan swallowed.

"Turn off the lights and move on." Li Yi ordered.

The heartbeats of all five of them were almost disordered, and they moved forward again, all around them were light and brighter.

Swim down, and the light in the entire passage gradually became stronger.

Swim further, upwards, the passage is U line.

Then they saw the thin ice on it, and they pierced it with the drill on their hands. The ice broke and it was bright and bright.

"Two people took down the oxygen cylinders and gave them to the other three. They left behind the camera. Two people went up and found their way back from above."

Li Yi knew where the light came from, and U-shaped passages appeared in some places, and the area was still very large.

It should be a hole here. The sunlight came in, through various scattering and refraction, into the underground lake.

It provides the creatures inside with the light needed for photosynthesis, and then the fish and shrimps grow inside.

"Xiao Yi, are those gold?" Li Dan still stared at the matter.

Others also shine brightly, a lot of gold.

Li Yi shook his head regretfully: "Pyrite ore is definitely not gold, but this mine..."

Li Yi struggled again. In order to ensure the brightness of the underground lake, this U-shaped channel mine could not be mined.

Digging in other places is no problem, you need to send someone to protect it.

If it is changed to him, this will become an underground lake diving area, and everyone will come to play diving, provided that the black fish sticks are cleaned up.

"Why not gold?" Li Dan couldn't accept this result for a while.

Li Yi smiled and explained patiently: "This place we live in is called Earth, many years ago..."

He popularized science and told the people around that gold has a high density, as well as platinum, tungsten, iridium, and osmium.

Of these things, tungsten should be the most abundant, and there are also many others.

But a long time ago, the earth was full of lava, dense and not as much metal as tungsten, and it sank.

So there is magma beneath the ground, and there is a lot of gold there. If anyone can take it out, every family can use it to build a house.

And what you see now is absolutely impossible to be gold. According to what you see, there can be millions of tons.

Li Yi's explanation was very straightforward and detailed, and everyone listened very carefully.

"Xiao Yi, how do you know?" Li Dan is not thinking about gold now, he is thinking about Li Yi.

"It was all taught by the masters. Thirty years ago, I just..." Li Yi began to push again, pushing on the masters.

No one believes, you are only twenty after the New Year, okay?

But believe what Li Yi said, the earth is round, and they would have known it a long time ago without Li Yi.

It turns out that there was a time like that on the earth, and the gold fell underneath it.

"Can gold be taken out of the ground?" Wu Jieyu cared more about practical issues.

"Magma, volcanoes, and Northern History have a cloud: There are volcanoes in the southern border of the country, and the rocks near the mountains are sintered, and the flowing land is solid for dozens of miles. People take medicine, that is, stone flows and yellows.

There is a little bit of it here. Only in a hotter place can you get gold. Who can go down? "

Li Yi told Wu Jieyu that the volcano was the beginning, after which it was all flowing and boiling metal.

What does it feel like pouring iron on your body? From head to toe, I guess it feels nothing in an instant.

"Li Lang, who did Beishi do?" Princess Yongmu had no impression at all.

"Li Yanshou and Li Xialing studied the history of the country during the Zhenguan period."

Li Yi gave the answer, so skilled, he found out what he wanted to check.

Explain that the speed of checking information by yourself and the proficiency in system application are manifestations of your ability.

system:"……"

Everyone believed again, the names were all spoken, and there were still words.

The words Li Yanshou took are quite interesting, and they complement the name.

Go back and check, you can find it during the Zhenguan period.

"Is it so knowledgeable?" Liu Jieyu looked at her daughter, then at Li Yi, satisfied.

She thinks Xiao Yi is a good kid~www.wuxiaspot.com~ We need wealth and talent, but the key is to be beautiful and delicate.

Regardless of his good looks, he can still play well.

He was kind to his daughter, spoiled all day long, and was not restricted to the Lijiazhuangzi, and got Wentianlanxiang Pavilion outside.

After planting Hericium erinaceus, the annual income of 1.8 million yuan will also belong to his daughter.

The key is not to look for women outside. The Nanqu'Everyone' from Pingkangfang has never happened before.

As for Xiaolan, Xiaolan belongs to a daughter and will not compete with her daughter.

Such a son-in-law, better than...

Liu Jieyu thought about taking a look at Li Longji, there was nothing to say, Li Longji had too many women.

Fortunately, I don't continue to look for it now, just those before.

Come here by yourself, what... it's good!

Queen Wang and Wu Jieyu are not suitable, so she will have another one.
