Lin Han stood at the exit of the airport, the flow of people on the opposite side came and went, and the sound of suitcases rolling on the ground came and went.

After a while, a young man in a white shirt and jeans pulled a suitcase and walked in the direction of Lin Han.

After a few steps, Song Shuqing walked a few steps with his suitcase, looking quite struggling, and it seemed that the contents of the suitcase were quite heavy.

"I'm tired to death!" Song Shuqing exhaled, "It took me a lot of effort to get these things." ”

Lin Han took the suitcase, and a cold touch came over, making him look surprised.

Song Shuqing explained: "I stuffed some dry ice in the suitcase to reduce the metabolic rate of the strain. ”

"How many strains did you buy?"

"There are a total of 127 servings, all of which are strains with excellent degradation and oxidative decomposition capabilities, 200,000 yuan are basically spent, and I have advanced hundreds of yuan for the road expenses. ”

"I'll reimburse you for your travel expenses when you go back. ”

Song Shuqing waved his hand: "Don't mention the matter of a few hundred yuan, you just need to do a good job of a few rivers in Tianhu Village." ”

"The river in Tianhu Village has almost been purified by me several times. ”

"How is that possible? It's only been two days. Song Shuqing clearly didn't believe it.

Lin Han smiled: "I will still lie to you, you can go back and see." ”

Randomly, he said: "By the way, I have walked around Tianhu Village a few times in the past two days, and I found that the environmental problems in this village are quite serious." ”

Song Shuqing sighed slightly: "Isn't it all like this now...... I would like to improve the environment of the village, but I can't do it. ”

"The excessive use of chemical fertilizers, pesticides, and sewage irrigated in the land has caused the soil organic matter to decline and form compaction, and various harmful substances have gradually affected the crops in the land, causing endless harm......

Lin Han thought for a while: "Actually, I can also help you solve the problem of soil remediation." ”

Song Shuqing was stunned for a moment, and then shook his head: "Where is the soil so easy to repair, you think it's a computer." ”

"It really won't be possible to completely restore the soil for a while. However, I can help you remove the pollutants in the soil. Lin Han said.

"No kidding. ”

"I'll go to your village in a few days and help you get rid of the soil. Lin Han didn't explain much, and said with a smile.

On the next step, he lifted the suitcase with one hand, walked to the side of the car with ease, put it in the trunk, and then stepped forward to open the door.

Lin Han's series of actions were extremely casual, but after Song Shuqing saw it, his body stiffened, and his face was full of incredulity.

He has been a soldier for two years, and his strength is much stronger than that of ordinary people, but it is difficult to carry this suitcase for free.

Lin Han's physique was clear to him, but the scene in front of him was ......

Could it be that I'm carrying a fake luggage?

......

With his suitcase, Lin Han returned to the Vientiane Sewage Treatment Plant.

"Abin, have you bought the incubator?"

Before going to pick up Song Shuqing, he asked Xiao Bin to buy an incubator to store these strains.

"Bought it. ”

Xiao Bin hurriedly pulled out a blue incubator from under the table, about the size of a suitcase.

"Boss, why do you buy this incubator?"

Lin Han didn't answer him, but carefully put the suitcase on the ground, and then unzipped it. This action made Xiao Bin very curious, and his eyes looked straight into the suitcase.

Even Shen Xiaolan couldn't help but glance sideways a few times.

After opening the suitcase, the inside is first covered with a layer of canvas, which is somewhat damp, and under the canvas is a layer of plastic film.

Lifting the plastic film, there is a thin layer of dry ice inside, which is cold, and underneath the dry ice is a transparent plastic box with several stacks of petri dishes, all sealed and neatly fixed in the box with duct tape.

Among the 127 petri dishes, they are of various colors, and the names of the strains are marked with markers.

Xiao Bin's eyes widened, "What is this?"

To the average person, these are just colorful petri dishes, and they don't know anything about the strains they contain.

However, in Lin Han's perception, among these petri dishes, there was a group of almost identical bacteria, which were moving slowly in the low temperature environment.

These artificially cultivated strains are very different from the microorganisms that can be found everywhere.

For example, the microorganisms that can be found everywhere in nature are like stones everywhere, which look diverse, but in general they are all unremarkable.

These artificially cultivated strains are like polished and carved sculptures, with strong and prominent characteristics, which are almost different from stones.

Moreover, these strains not only have strong characteristics and show vitality, but also far stronger than ordinary microorganisms, showing super tolerance and adaptability.

Bacteria from a professional class are just different.

Under Lin Han's concentrated consciousness, these strains became almost stationary, and the efficiency of metabolism and life activities was reduced to the lowest level.

Then, he took a glass from his side and poured a little of the liquid from the petri dish into the cup one by one.

Under his deliberate control, although only a few drops of the nutrient solution in each petri dish were poured out, most of the strains entered the glass, like dumplings, making the bacteria in the glass extremely dense.

Bacteria are extremely dense and diverse, and in general, there is a high probability of mass death as well as engulfment of each other.

However, due to Lin Han's metabolism to the lowest level in advance, all life activities almost stopped, and although a large number of bacteria had gathered in a glass, they could still be peaceful and calm.

One hundred and twenty-seven petri dishes, even if only a few drops are poured out of each dish, fills the cup quickly.

A large number of strains make the glass appear colorful and cloudy and sticky, which looks dangerous and mysterious.

"Abin, reseal the petri dishes and put them in the incubator to keep the temperature low. Lin Han said, "Then let the workers add organic matter to the water." ”

With that, he picked up the glass, went to the cistern at the inlet of the factory, and poured all the viscous liquid into the water, while relieving the suppression of the metabolic level of these strains.

As soon as the dragon returned to the sea, these powerful specialized bacteria immediately became active again, and the entire reservoir was filled in an instant.

When the workers added a large amount of organic matter to the water as bacterial nutrients, under the manipulation of Lin Han, 127 kinds of bacteria suddenly entered a state of excitement, and quickly began to multiply, and the number increased geometrically, and other ordinary microorganisms almost lost all their living space in a very short period of time......
