Xiang Ying blushed, pursed her lips and nodded, and said, "Xiaolin, don't get me wrong, I'm not trying to rush you, no matter how long it takes, I will wait for you."

Li Rui smiled and said, "Fool, how can I not know your mind, go to sleep."

Xiang Ying quickly fell asleep, and when she got up, it was already past two o'clock in the afternoon.

At this time, Li Rui had also woken up, and he asked with a smile, "What is the difference between sleeping here and at home?"

Xiang Ying said with a smile: "There must be a difference, this is the first time I have slept in the mountains, and it feels exciting and fun."

Li Rui nodded and said, "Okay, let's get up quickly and I'll take you over there."

Xiang Ying snorted, and after the two of them cleaned up, Li Rui took her to the waterhole where he returned with Han Yan last time, where he found extremely rare orchids.

Although Xiang Ying grew up in the Nong 2 tribe, she had never been here, and she was very excited when she saw that there was a small waterfall here. She stood at the water's edge and looked up at Li Rui, and asked with a smile, "Xiaolin, this water is flowing out of the deep mountains?"

"Yes!" Li Rui nodded and said, "This is also the last time I found out that there is a small waterfall here, you can see how clear the water here is, there is no problem for people to drink it directly."

Xiang Ying looked at the entire waterhole and nodded, "Yes, this place is simply a fairyland on earth, the last pure land left by God to the suburbs, right?"

Li Rui smiled: "It's hard to say whether it's the last piece or not, but it's indeed a pure land. The reason why I couldn't feed the Morinda before me was because of the soil pollution, but here is different, the air, water and soil here are all pollution-free, I really hope that there will be more pure land like this in the suburbs."

Xiang Ying nodded and said, "How can there be any way to improve pollution?"

Li Rui shook his head and said, "At present, there is no particularly good way, and the focus of pollution is different in different places, we mainly have air and soil here, water sources to the south, and soil erosion in the west, so we must implement precise policies."

"I've heard that planting trees can improve pollution, is that possible?"

Li Rui smiled: "It's useless, since the soil has been polluted, the kind of tree that goes down, even if it doesn't die, will be polluted, unless it ......."

At this time, a thought suddenly popped up in Li Rui's mind, "Alas, why didn't I think that there are some plants that can not only purify the air, but also adsorb pollutants in the soil and air."

"yes, what kind of plant is it?" Xiang Ying was pleasantly surprised.

"Indian mustard, for example, has a super-accumulation effect on specific metals and is often introduced as a plant for plant soil remediation abroad. It removes 3 times more cadmium than other species, reduces lead by 28% and selenium by up to 48%, and is also effective against zinc, mercury and copper. Indian mustard has been used to remove radioactive Cs137 from abandoned nuclear power plants." Li Rui replied, "Another example is Sedum in the southeast, a plant with excessive accumulation of zinc, cadmium and lead found in some ancient lead-zinc mining areas in recent years, which can absorb cadmium, zinc and lead into the aboveground part of the plant, effectively reducing soil heavy metal pollution."

Although Xiang Ying didn't know what this Indian mustard and southeast sedum were, she still couldn't help but applaud and said, "Okay, okay, then the environment here will be saved."

The results showed that the biological yield and the accumulation of heavy metals in the shoots of Sedum sedum could be improved by taking effective auxiliary cultivation measures and improving the soil environment, and the efficiency of heavy metal restoration could be improved. For example, intercropping of maize and southeast sedum can significantly reduce the leaching and content of zinc and cadmium in polluted soil. Proper nitrogen and phosphorus nutrition can improve the root development of Sedum sedum, especially the use of ammonium sulfate, which can improve the remediation ability of plants to zinc and cadmium pollution.

"Well, Southeast Sedum not only has a strong tolerance and super-accumulation of excessive amounts of zinc, cadmium, and lead in the soil, but also has the characteristics of perennial, vegetative reproduction, large biomass, and suitable for mowing. At the same time, it has strong adaptability, resistance to harsh habitats such as barrenness, drought and strong light, strong ornamentality, and is an excellent plant for the implementation of phytoremediation and ecological greening

。」 Li Rui said, "According to this characteristic, it can be cultivated not only in the north, but also in the west and south."

"Uh-huh, that's great." Xiang Ying said with a look of adoration.

"Thanks to the inspiration you gave me, I should have thought of it a long time ago." Li Rui said with a smile, "There is also centipede grass, which can enrich a large number of heavy metals such as arsenic and lead in polluted soil, and is a plant with excessive arsenic accumulation. Field investigations have shown that arsenic levels in centipede grass can reach 1-2%. Centipede grass not only has a strong tolerance and enrichment ability to arsenic, but also has fast growth, large biomass, wide geographical distribution and strong adaptability. It has good application prospects in the remediation of arsenic-contaminated environments."

"Can you find these plants here?"

Li Rui said, "In addition to Indian mustard, I believe that several others can be found."

"Mmmm, Lin Kun, I found that you are really too godly, you are simply the savior of the people in the suburbs, being able to be your woman is really a blessing that I cultivated in my previous life!"

After speaking, Xiang Ying stepped on a stone by the river and wanted to wash his hands, Li Rui walked up to him and said with a smile: "The water here is too cold, and there is a lake below, I will take you there."

Immediately, Li Rui took Xiang Ying's hand and walked down the river, walked for about ten minutes, and sure enough, there was a lake, which Li Rui accidentally found when he went up the mountain to collect medicine.

Looking at the clear lake water, Xiang Ying was very happy, and when she walked to the river, the water was really warm, Xiang Ying looked up at Li Rui and asked with a smile, "Xiaolin, this water is not deep, can I take a bath here?"

Li Rui nodded and said with a smile, "This water is not deep, I soaked here for a long time last time, but aren't you here for a period?"

Xiang Ying nodded and said, "Yesterday was the last day, today is fine, I just climbed the mountain and sweated, and the water is so clear, it would be a pity if I didn't wash it."

Li Rui smiled and said, "Cheng, then you can wash it, anyway, there is no one else."

Xiang Ying smiled and said, "You turn around, I'll take off my clothes,"

"Hehe, we both slept together, and we still see each other like this." Immediately, Li Rui turned his back.

The whole body entered the water, and Xiang Ying only felt very comfortable soaking in the water, so she looked at Li Rui and said with a smile, "You can turn around now."

Li Rui turned his head and glanced at Xiang Ying in the river, smiled and said, "Are you all ***?"

"Hooligans!" Xiang Ying asked with a blushing face, and subconsciously hurriedly protected her chest.

Li Rui grinned and said, "Lie to you, you're all in the water, what do I think."

Xiang Ying breathed a sigh of relief, her cheeks flushed and said, "You, you turn around, don't look at it again."

"Cheng, you wash it well, I'll sit next to you and wait for you!" Saying that, Li Rui walked to the side.

Xiang Ying saw that Li Rui was really going away, and immediately said, "Lin Kun, don't go too far, I'm scared here alone."

Li Rui was speechless for a while, and said with a smile: "You let me stop looking at you for a while, and I'm afraid that I will go away for a while, I think I'd better just come down and accompany you, it's definitely not interesting for you to play in the water alone."

Saying that, Li Rui took off his clothes directly, jumped into the river, and splashed the water on the other party.

was splashed with water, Xiang Ying was not to be outdone, and suddenly the two of them made a splash in the water......

Half an hour later, the two went ashore to clean up, and Li Rui took Xiang Ying down the mountain.

On the way, Xiang Ying looked at Li Rui and said with a smile: "Thank you for accompanying me up the mountain today, I had a great time today."

Li Rui subconsciously glanced at Xiang Ying and her wet hair, and said with a smile: "This thank you is not said with your mouth, you have to give me a reward or something."

How could Xiang Ying not know this guy's thoughts, and immediately pulled Li Rui and kissed him, then he blushed and smiled, "What about this reward?"

"Can't you give the bigger one?" Saying that, Li Rui hugged Xiang Ying and kissed him, gave him a deep kiss, and said, "I will come like this in the future."

Xiang Ying's cheeks suddenly turned red, and she glanced at Li Rui, and then said, "Now that you're satisfied, let's go quickly, it'll be dark in a while."

"Uh-huh, let's hurry down the mountain."

When the two of them arrived home, it was already past six o'clock, Li Rui sent Xiang Ying to the door, and by the way, he went into the house to take a look at Xiang Ying's grandfather's condition, and saw that there was basically no problem, so he returned home.

Soon a day passed, and the next day Li Rui had just finished breakfast, when Aunt Ma next door came to his house and said with a smile: "Xiaolin, it's been two days, when will you go to He Laogui's house to ask for debts?"

Not only Aunt Ma, but many people in the tribe have been waiting for Li Rui to go to He Laogui to ask for accounts in the past two days.

Li Ruiden was speechless, thinking that these guys all like to watch the excitement so much, but it is good for many people to ask for debts, so he smiled and said, "Auntie, I'll go after dinner."

Aunt Ma smiled when she heard this and said, "Then you have to hurry, the big guy still wants to help you ask for debts together."

In fact, many people in the tribe don't like He Laogui and He Dabeard, so many people want to see those two guys unlucky.

Li Rui nodded and said okay, and after waiting for the other party to leave, he sat at home for a while before going out, and arrived at He Lao's house. The people in the tribe saw that Li Rui had already gone, so they also followed.

When he arrived at home, He Laogui, who had just finished breakfast, saw Li Rui coming and invited Li Rui to the house.

According to his He Laogui's temper, if other people dare to come to the door to ask for debts, He Laogui will definitely be furious, and he can play any tricks or anything when the time comes, but he doesn't dare in front of Li Rui, he knows this guy's skills, let alone beating him, even seven or eight are not opponents.

Besides, although he He Laogui is not doing his job and is looked down upon, he is also a person who wants to be faced, and they bragged in front of all the fallen people before, if this is a trick, he will definitely be laughed at by all the fallen people in the future.

Li Rui sat on the side of the kang and asked He Laogui to call He Dabeard to come over, and at this time everyone gathered in front of him to discuss.

The two families were not far apart, and a few minutes later, He Dabeard came over, looking at He Laogui and the two, Li Rui asked with a smile, "Is the money ready?"

The two glanced at each other, He Laogui nodded and said with a smile: "It's okay, it's just 10,000 yuan, which I scraped together, and I borrowed 5,000 yuan to make up."

As he spoke, He Laogui took out a black plastic bag from his pocket and handed it to Li Rui, Li Rui took it and looked at it again and said, "Cheng, it's just 10,000 yuan!"

As he spoke, he looked up at He Dabeard and said, "Brother Beard, what about you?"

He Dabeard paused for a moment, then took out a wad of money from it and said, "Xiaolin, I have searched all the people in the past two days, but there is still a difference of 1,000 yuan, I still have children and wives here, do you see if this 1,000 yuan can be ......."

Before he finished speaking, Li Rui glanced at it, and immediately waved his hand to interrupt, "No, I have to take it out today."

At this time, everyone immediately talked about it, and some people whispered that Li Rui was too cold-blooded, not like usual, but most people supported Li Rui, but he had his own way of dealing with Li Rui.

He Dabeard's face sank when he heard this, although he was very angry, but he didn't dare to be mad in front of Li Rui, he didn't expect this guy to be so cold-blooded, and suddenly He Dabeard looked at Li Rui with a gloomy face.

Li Rui tilted his head and looked at the other party and said with a smile: "Brother Huzi, give you a way, either you owe this thousand yuan first, and we will calculate it according to the loan sharks outside, or you can take out a thousand yuan now, and you can choose these two."
