The Female Assistant of Wei Yuyan Shuangfei

Chapter 222 The First Problem

The children's examination was currently being held in Laigu County, and the streets outside the county school had long been controlled by yamen runners to prevent quarrels from disrupting the examination.

Unexpectedly! At this moment, Shanghe Township, a hundred miles away, encountered the first problem of digging a canal, which was to divert water to the mountain.

"Master Wang! What's the situation?"

Xie Tingwen hurried over in a panic, asking loudly and impatiently as he ran.

As Xie Tingwen had been busy for nearly half a month, her originally fair and smooth skin had become a little rough and dark, completely losing the delicate and tender feeling she had before.

But because of this, the whole person has a more majestic and brave temperament, and looks more like a battle-hardened general.

Wang Lang clenched his fists, stroked his hands with a little helplessness and said: "This is the third time I have experimented. The water flow has indeed increased after the height of the cofferdam has increased, but the power to reach the second layer is still not enough."

"Yeah!~"

Xie Tingwen looked a little surprised as he stood on the ship and looked at the third canal being dug on the cliff. He felt a little heavy in his heart for a moment.

Each layer of the water diversion must be tested to ensure that it is correct before digging the next one. These two alone are also very painstaking.

But gunpowder cannot be used to dig channels on cliffs, otherwise the entire terrain of the mountain may be changed, which would then create new problems.

As a last resort, Wang Lang resorted to the old method of using wood to calcine the stone and then splashing it with Red River water, causing the stone to expand and facilitate mining.

But the current problem is lack of motivation, which also touches on Xie Tingwen's blind spots in knowledge, so he naturally can't help much.

"Do you want to try again?"

Wang Lang pondered for a moment after hearing this, and looked at the people busy on the cliff. His heart sank, and he immediately waved his hand and said, "Prepare the cofferdam, and try again."

"Yes!~" the people waiting on the side hurriedly echoed.

They quickly carried stones and sandbags to raise the cofferdam again, then emptied the water in the pipes and cleaned the waterwheel blades buried underneath, waiting for Wang Lang's instructions.

Looking at the people who were ready, Wang Lang waved his hand and said, "Let's go."

Without hesitation, everyone pushed the stones into the river. As the water level rose, the river water instantly rushed in and pushed the fan blades to rotate.

Xie Tingwen watched everything nervously, praying secretly in his heart, hoping that this time it would be successful.

Obviously, in the face of science, all unrealistic ideas are futile.

When the water flow converges to the second layer, the speed increases a little, but it is still not enough to drive the water wheel in the second section.

After passing through the first layer of canals, the water of the Red River falls into the Red River again.

Xie Tingwen looked at everything in front of him, and his heart was mixed with confusion. "How does this flow compare to the previous one?"

“It’s a lot faster, but still not enough.”

"Then raise it again. Raise the cofferdam to a higher level." Xie Tingwen said coldly.

"Sir! No."

Wang Lang hurriedly held the handrail and said, "This cofferdam has already divided the Red River's water flow by 20%. It is fine in the dry season, but it will not be able to hold up in the flood season."

"What can we do?"

While Xie Tingwen was thinking secretly, he suddenly had an idea and asked anxiously, "I have also seen Shu Ting's drawing. Can we change the angle of the windmill to increase the speed of the water flow?"

Wang Lang shook his head and pointed to a corner of the ship, saying, "Sir! I have tried this method before. Changing the angle of the windmill caused serious wear and tear on the blades. It can't last more than an hour."

Xie Tingwen looked at the broken pieces of iron on the ground. From the traces of fracture, it was obvious that they were torn apart. This water flow should obviously not be underestimated.

Just as the two were thinking about countermeasures, a minor clerk from the Gongya quickly stepped forward and leaned over to say, "I am Ji Shen, a clerk from the Gongya. I am honored to meet Mr. Xie and Mr. Wang."

"Yeah!~"

Xie Tingwen nodded slightly and said, "What do you want?"

"Reporting to the Lord! Master Wang tried several times, and I also looked at it several times on the second floor of the mountain gate."

Ji Shen paused for a moment and said in a deep voice, "Although I am not as smart as you, but after these experiments..."

"Do you suspect that the young lady's plan is wrong?" Wang Lang asked coldly.

Nowadays, in the entire county government, if we were to ask who admires Xie Shuting the most, apart from Si Nong Chen Ping, it would be Wang Lang.

Ever since Xie Shuting took out the blueprint, he has been impressed by Xie Shuting's mysterious thoughts. In his opinion, it is impossible for the lady to be wrong.

Seeing that Wang Lang was about to get angry, Ji Shen quickly responded, "Master Wang, please don't be angry. Please allow me to explain in detail."

"You say." Wang Lang said coldly.

"Yes!~"

Ji Shen bowed and pointed to the second-layer water channel: "I listened carefully during the previous experiments. There is indeed water flowing in the pipe, but the windmill can't move it fast enough, so the water can't get out."

"Oh!~"

Xie Tingwen's eyes lit up, and he asked with a smile: "Have you figured out the problem?"

"I dare not, it was also Master Wang who accidentally reminded me of this."

Ji Shen cupped his hands, then changed the subject and said, "If we regard the second layer as the first layer, then the solution to increase the flow of water is to build a cofferdam, but we cannot add a cofferdam to the second layer..."

"Can't increase the cofferdam...can't increase..."

Wang Lang pondered Ji Shen's words secretly, and suddenly his eyes lit up and said, "If we follow what the lady wrote on the drawing, in addition to changing the cofferdam, we can also modify the size of the pipeline."

"That's right!"

Ji Shen stroked his hand and said, "The specific situation still depends on the results of the final experiment. This is just a small guess."

"No matter what method it is, we should try it as long as there is a chance." Xie Tingwen said softly.

"good."

Wang Lang couldn't hide his joy, and hurriedly ordered the yamen runner beside him: "Go and inform Wu Lizheng quickly, and ask him to make the four-inch and three-inch pipes quickly."

"Yes!" The bailiff responded and quickly walked down from the ship.

Since lime was needed to build river embankments and repair canals, Xie Tingwen simply opened a kiln factory in Xiahe Township.

This clay pipe was not very technically demanding, so it naturally fell to Wu Yang.

"Are you sure you didn't send the wrong message?" Wu Yang looked at the visitor with a puzzled look on his face.

"Wu Lizheng! Lord Xie was also present at the time. I heard it all. But Officer Wang asked you to make four-inch and three-inch ceramic pipes quickly."

Wu Yang did not doubt him. He looked at the earthen kiln that was about to be sealed and hurriedly shouted, "Don't seal the kiln yet. Wait a minute."

Everyone stopped what they were doing upon hearing this, while Wu Yang quickly walked towards the workshop and gave a few instructions to the bricklayer.
