'It seems that the knight's training needs to spend more time and improve the power of will as much as possible.'

"Just rest in bed."

Xue Lai got up and went out while he was sitting cross-legged in the corner. When he came back, he brought back a soft single bed with quilts.

"Thank you." Colin opened his eyes and did not refuse. He really needed a good rest.

"You're welcome." Xue Lai shook his head, "Now you are the only one who can observe farmland pollution, and I can't help you much..."

"Your accumulation of witchcraft knowledge far exceeds mine. When the time comes to figure out the characteristics of pollution and research solutions, I will need to rely on you."

Colin smiled and lay on the bed.

Before he fell asleep completely, he suddenly thought - since he can observe farmland pollution, can he also observe and study the dirty talk that is very similar in nature?

…

Time flies and it’s August.

The scorching sun is shining in the sky, and the clouds in the sky seem to be whiter than in other seasons.

"Hurry up and work hard. The ten people who perform best tonight can get a small piece of black bread!"

North of Golden Wheat Ear.

Outside the city wall, there used to be only a few shabby serf huts in the wilderness, but now several huge wooden frames have been erected.

'If the farmland can be restored, this will be a good food processing factory or a large granary.'

Colin passed by and took a look on his way to the laboratory, thinking to himself.

The obedience of the serfs was much higher than he imagined. They did not need wages at all, and they did not care how tiring the work was. As long as they had food and housing, they were satisfied.

This period of time really saved him a lot of worry and allowed him to spend more time studying farmland pollution.

Arriving at the hidden experimental location, Colin reached the deepest part of the laboratory with ease.

Xue Lai was lying down writing something. Judging from the amount of manuscript paper piled next to him, he must have been up all night again.

"You should also pay attention to rest." Colin couldn't help but remind him.

"I will, but a long time has passed, and the information you gave is enough to carry out research..." Xue Lai raised his head and smiled, his face unchanged, but his smooth snow hair was a bit rough, revealing the owner's fatigue.

Colin said no more and walked quickly to the experimental table.

I don't know if he was stimulated by Xue Lai's words, but he felt that his condition today was particularly good, and he even felt that the pressure of the god's pollution in front of him was less.

About an hour and a half later, Colin quit the research, with a look of joy on his face.

Xue Lai has been waiting aside for a long time, with some worry on his face, "Why did you study for half an hour longer than usual today?"

"I understand the mechanism of farmland pollution!" Colin did not answer, but said excitedly to her,

"This time I finally eliminated all the remaining factors and determined that farmland pollution did not indirectly affect plant growth, but directly caused the withering of plants.

Moreover, I also observed a special phenomenon. Farmland pollution does not enter the plants with water or other elements, but enters actively!"

Xue Lai was slightly startled, and then his face also lit up with joy.

This may not seem like a big discovery, but in fact it is at least a staged achievement for the study of farmland pollution!

They are one step closer to successfully solving farmland pollution!
