What Jia Siqian took out was a bag of cotton as thin as silk, as white as snow, and as soft as a cloud!

In the territory of the Han Dynasty, there was only kapok and no cotton, Guo Shoujing and Li Daoyuan were well-informed, but they had never seen cotton.

However, both were well-read scientific powerhouses and immediately realized the value of this thing.

"Could this be the cotton from the Western Regions?"

"That's right! That's cotton! Liu Mang replied for Jia Sixian, but he didn't expect that Jia Siqian would really succeed in the trial!

"This year, I only tried to plant a few acres, and in the spring of next year, I can sow a large area!"

Guo Shoujing and Li Daoyuan gently touched the white cotton, admired Jia Sixian, and were full of praise.

At this point, it's a good opportunity to settle the dispute between them.

The reason for the dispute between the three people has been figured out.

In order to try to plant cotton and new varieties of wheat, Jia Siqian insisted on digging a ditch for the experimental field.

Guo Shoujing agreed to dig a ditch for Jia Sixian's experimental field.

However, Li Daoyuan believed that Guo Shoujing's plan was not feasible, and even suspected that Guo Shoujing was seeking personal gain.

The importance of cotton and new wheat seeds is understood by both Guo and Li. With Liu Mang as the arbitrator, the three finally stopped arguing.

However, challenges remain.

Li Daoyuan opposed Guo Shoujing's plan on the grounds that the composition of the underground soil in the Jishan area was relatively special.

The layers below the land are complex, simply put, the upper layer is the soil layer with good permeability, and the lower layer is the rock and soil layer that is not easy to permeate.

According to Li Daoyuan's investigation, the soil layer in the Jishan area is relatively thin. In Guo Shoujing's plan, the ditch is dug deep and needs to be excavated below the rock and soil layer.

In this way, not only will a lot of forced labor be required, but the rock and soil layers will be damaged, and the canal water will leak a lot, and it will be impossible to direct the water to the test field.

This ditch was temporarily added by Guo Shoujing at the request of Jia Sixian, and it was not well considered.

Guo Shoujing also admitted that Li Daoyuan had a point. However, the area around Jishan is high, and if the ditch is not dug deeply, it is impossible to channel the Fenshui into the canal.

Things are figured out. Liu Mang's persuasion is also easy.

Several people have been arguing before, because Li Daoyuan didn't know the role of Jia Sixian's field. Therefore, we vigorously oppose the waste of manpower and financial resources by digging ditches to divert water just for a dozen acres of farmland.

Liu Mang emphasized that Jia Sixian's experimental field. It is a major matter related to the national economy and people's livelihood, and we must give priority to ensuring water supply.

As for how to solve it, it is not a problem at all for these three great scientists.

Shallow excavation, sectionalization, water truck diversion into the canal, echelon transportation can be.

……

Returning to General Wei and continuing to deal with official business, the bronze mirror suddenly shook.

The One-Star Special Summons are about to expire, so please use them as soon as possible......

Summon!

Please select the summoning era: Sui, late Song and early Yuan Dynasty

Choose the late Song and early Yuan ......

"Young master." Wan'er's voice came from outside the door.

Liu Mang panicked.

In the past, when they were called, they all bolted the door of the room. Prevent others from discovering the secrets of the bronze mirror.

Fang Cai's summoning, it happened suddenly, Liu Mang was careless and didn't close the door.

Although Wan'er is a confidant, the bronze mirror is very important, and she can't be found out.

Liu Mang hurriedly agreed and quickly hid the bronze mirror.

"Young master," Wan'er pushed the door in, smiling, "our son is here!" ”

"Huh? My godson is here? I'll go right over. ”

Wan'er held Liu Mang's arm. While walking to the backyard, he said: "Xiaocui came to Anyi from Pingyang to buy things, and brought her son by the way." We're going to Luoyang, and it's not easy to see Xiaocui and her mother in the future. Let's have a reunion dinner tonight. ”

"Okay. Ah! Liu Mang was suddenly surprised.

"Don't worry." Wan'er rubbed Liu Mang's arm vigorously, "Knowing that you are busy, I have already prepared a gift for Shi An." ”

Wan'er's empathy made Liu Mang couldn't help but turn his head and kiss it.

Turning a corner, Wan'er ran back to the room, when she came out. Holding a small, boxy wooden box in his hand.

The wooden box looks unremarkable, with an empty egg on one side open, and a button on top of the box.

"Young master, there are interesting things in the cave!"

Wan'er handed the box to Liu Mang, who narrowed his eyes and approached the hole in the box.

"Whew!"

An object suddenly jumped out of the air, startling Liu Mang!

Wan'er giggled.

"What's that?" Liu Mang touched the back of his head, and when he looked at it, what came out of the hole was a little mouse!

Wan'er let go of the button, and the little mouse shrank back.

"Haha, it's fun." Liu Mang took it and pressed the button at Wan'er.

Although Wan'er knew that it was clever, but the little mouse jumped out, and Wan'er was still startled.

"Fun, right?"

"That's good, where did you get it?"

"I heard a few days ago that their mother and son were coming, and I asked Yu Hao to do it."

"Oh?" Liu Mang was a little surprised.

Yu Hao was Yu Wenkai's subordinate, and he originally worked in Luoyang.

The imperial court wants to return to the east, and in line with the principle of economy, some items that can be used here in Anyi will be transported to Luoyang one after another.

In the Anyi court, there are many large items that are inconvenient to carry over long distances, and Yu Wenkai sent Yu Hao to Anyi to guide dismantling and shipping.

Yu Hao came to Anyi, Liu Mang knew. What Liu Mang was surprised by was Yu Hao's craftsmanship.

Last time in Qi County, Yu Hao made a gun, held an axe, and flew up and down.

Liu Mang was afraid that he would destroy the best materials, so he watched from the sidelines, and finally realized that it was shocking! What is it called!

I don't have to say anything about the gun I made, but I have to say that the process is too exciting!

Liu Mang thought that Yu Hao could only do a lot of skillful work, but he didn't expect to have such exquisite craftsmanship.

"Wan'er, didn't let the family work in vain, did you?"

Wan'er smiled. "Of course not, I brought him a jar of wine."

This Yu Hao, born an alcoholic, can't help it......

……

The two came to the door of the innocent house, and before they entered the house, they saw a fat buttocks first!

Xiao Cui was pouting her buttocks, lying on the edge of the couch, reaching out from under the couch to pull out Xiao An.

Liu Mang couldn't help laughing, he couldn't go in this meeting.

Wan'er entered the house with a smile and dragged Xiao Cui Niang and the two children. "When I am a mother, I don't pay attention to my image. Quick, the young master is here. ”

Liu Mang entered the house at this time.

Xiaocui will not be embarrassed, only helpless. "Young master, what do you say this kid can do, he will climb since he fights, so he will drill everywhere, where is dark, where is it difficult to find it."

Liu Mang and Wujian Wan'er couldn't help laughing.

"Let him be, little one, leave him alone." Liu Mang picked up Shi An, Wan'er took the box and pressed it.

"Whew!"

The little mouse suddenly popped out.

Xiao An stared at the little mouse, and then, without accident, "squeaked" and cried in fright.

The crowd laughed and coaxed.

Liu Mang doted on Xiao An, hugged him around the house, and finally coaxed Xiao An into tears.

"Squeak, squeak, squeak......" Xiao An couldn't speak, stretched out his little hand like a rat's claw, and pointed to the beams in the house.

Liu Mang smiled secretly in his heart: This is right, the child of Shi Qian was born to drill holes and go to the beams of the house, which is more accurate than paternity testing and blood recognition......

……

After the reunion dinner, several women gathered together to talk.

Liu Mang returned to the study, remembering that Fang Cai's summoning was halfway through, and hurriedly took out the bronze mirror.

Hey?

Show that the summoning was successful?

It must have been in a hurry and hit the button.

Hey?

How do you summon a woman? (To be continued.) )
