The usage of a horseshoe shovel is similar to that of a Luoyang shovel.

When using it, stand upright, legs apart, hold the rod with both hands, place it in front of your chest, the head of the shovel is on the ground, and between the tip of the feet, and poke the ground downward. When the bottom of the horseshoe-shaped shovel is submerged in the soil, then rotate the shovel head continuously, hit it alternately, and then lift the shovel to cut out a piece of cylindrical soil.

By repeating this, you can continuously dig downwards.

A horseshoe shovel with long white wax poles can penetrate several feet into the ground. A deep cylindrical pit was cut out. The craftsmen of Ji Kingdom took out the soil they were cut out to weigh it to judge whether this place was suitable for building a city. As for tomb robbery, it has not yet become a trend. Besides, the royal cemetery was guarded by soldiers, and there were noble people in various gardens to guard the tombs. How could thieves enter? Today, the large-scale excavation of imperial tombs in the Han Dynasty should start with Dong Zhuo, and later promoted by Meng De.

Zhu Ling led a hundred people under his command, and with the Liang craftsmen of Ji Kingdom, Su Yue, multiplied several military vehicles in the army to the original camp. With Su Yue's order, the soldiers immediately formed a small camp, which could be attacked or defended. Then, the Liang craftsmen of Ji Kingdom scattered with a horse's hoof shovel, and poked the ground with force.

The soil is cut out and arranged in an orderly manner. Experienced Ji Country craftsmen can see the clues from the changes in the color of the soil layer alone.

in short.

Naturally deposited, intact and unmoved soil layers are different from those manually backfilled after excavation and depth.

Soon, the good craftsmen discovered something. They continued to poke downwards, and the white wax pole suddenly sank. Sand and dust gushed out, but there was no mud after picking up the shovel.

"How?" Zhu Ling asked in a low voice.

"A underground secret passage was dug through." Su Yue said softly.

"What should I do?" Zhu Ling asked again.

Su Yue's fingers had already digging holes around here, and the craftsman who was spreading dots in the shape of a "cross" said: "Find out the distribution rules of underground secret passages."

"What if I find out?" Zhu Ling asked three times.

"It depends on the size." Su Yue answered three times.

When craftsmen opened up the underground secret passage one after another, Su Yue's expression became more and more serious.

"Now, it's big or small." Zhu Ling couldn't help asking.

"The scope is very wide." Su Yue used his heart and thoughts. He wrote and painted on the drawing board, but he kept saying: "The thief has been hollowing out the entire Guangzong area for half a year. The secret passage is as secretly as a spider web, covering the entire area. It is still unknown when we were talking."

Zhu Ling subconsciously lowered her head and looked at the soles of her feet: "What should we do now?"

"Just just as the mine needs ventilation. With such a huge underground pipeline network and someone hides it, it must be equipped with ventilation holes. First find the nearest ventilation hole." As he said that, Su Yue suddenly stopped writing: "Then, I need to worry about the military waiting to accompany me down to see."

"Yeah!" Zhu Ling focused heavily. He couldn't find the authenticity, but he was good at fighting.

"Guangzong hidden a great master." Recalling the secret message from Hu Yu, a trace of haze rose in Su Yue's heart.

Nowadays, the mines are ventilated, illuminated and supported, and are very mature. For example, the Dongling Mine of the Chang Princess Tang Muyi: first dig a vertical shaft, then dig a cross-channel. In this way, the excavation is directly reached to the mining work surface. Ventilation, lighting, support and other facilities are set up between them.

The Yellow Turban Thief was like this under Guangzong. The only difference is not for mining. Whether it is for hiding soldiers or for other purposes. It is still unknown now.

By the way, the soil quality of Guangzong also enabled the rapid digging of the Yellow Turban thief.

Get back to the point.

"Finally found it!" Suddenly, a light shout was heard.

Seeing the craftsmen surrounding him, Zhu Ling also arrived with Su Yue.

The craftsman had cleared the surrounding sand. Zhu Ling looked carefully and saw that there were a broken bamboo that was buried deep in the soil. Then he asked: "There are no gaps around him, how to ventilate?"

"Look at the military man." The craftsman took the hook claws, hooked into the bamboo joints on the top, and pulled them out with force. He pulled the dead bamboo out of the ground. It seemed like a long bamboo growing on the ground, shrinking into the ground one by one.

The four walls of the bamboo tube have been hollowed out in sections and are being used for ventilation.

"Just use a thin bamboo to lift the bamboo tube high from below while the night is covered, and you can ventilate yourself." Su Yue looked around the vast open space: "There must be a lot of bamboo pores."

"So that's it." Zhu Ling suddenly woke up.

With just a bamboo forest, the thief can ventilate the entire underground tunnel. Such a simple and practical design is really unique.

However, the size of a fist-sized bamboo tube buried underground, and I don’t know how deep it can make people get into it. Su Yue’s desire to go down and explore was then vain. The inside story is far more complicated than he thought. Among the Yellow Turban thieves, there must be experts in the mechanical skills.

Seeing that Su Yue was silent, Zhu Ling did not dare to disturb him even though he knew that he was thinking hard about how to deal with it.

After a moment, Su Yue suddenly sighed: "For the current plan, there may be only one method left."

Seeing that Su Yue showed unbearableness, Zhu Ling said something to her mouth and swallowed it back by herself. This method must be extremely powerful and harming the world.

Several good craftsmen from Ji Guo also woke up one after another: "Could it be..."

"Yes." Su Yue calmed down: "Go back quickly, this plan needs to be discussed with Lu Cheqi."

"good."

Everyone got on the bus and turned back.

In the central army's large tent, after listening to Su Yue's plan, Lu Zhi's face was as deep as water: "I want to dig the Zhang River, will the water flood Guangzong?"

Su Yue nodded gently: "The Zhang River is abundant. Once it is poured into Guangzong, the underground secret passage excavated by the Yellow Turban Thief will be destroyed in an instant. As Xiaguan expected, the machinery and equipment in Guangzong city will also be destroyed together. This battle is Yi Er."

"There are hundreds of thousands of innocent people in Guangzong City." Lu Zhi asked, "May it be protected?"

Su Yue shook his head: "In a few months, such a huge underground secret passage can be dug out. I believe the people in the city have made great efforts. At this time, they may be hiding in underground caves, which is unknown."

"In this way, once the Zhang River floods, it will flood the crypts. Wouldn't the people all die?" Lu Zhi showed anger.

"Maybe that's the case." Su Yue told the truth. In fact, this is just the most extreme assumption. Even without considering ventilation, the thief would not be able to hide hundreds of thousands of people underground.

But Shen Pei stood up and said, "Ming Gong, I think that the so-called 'hundreds of thousands of people' are all Taiping disciples who defected to Zhang Jiao. Maybe, it is not innocent." The implication is that there is no need to take into account the life and death of these people.

"I have known the meaning of the south." Lu Zhi shook his head flatly: "However, this strategy is too cruel. Hundreds of thousands of people, regardless of age, young, women and children, drowned. Even if they defeated, what is the difference between my glorious heavenly han and those inhumane barbarians who eat raw meat and drink blood."

"Report to the general, there may be another way." Seeing that things cannot be done, Su Yue said again: "Give up the near and seek far away."

"How to look for the distance?" Feng Ji hurriedly got up and asked.

"Guangzong is close to the water of the water. This water is the branch of Zhang River, and the water flows gently. You can dig a long canal to lure this water into it." Su Yue said: "Just set up another water gate in the canal to block the incoming water. It will not be like Zhang River. Once the dike is broken, it will flood everywhere and cannot be cleaned up."

"The Zhang River is north again, and the Fu River enters it."

The Fong River is named after its origins in Fong Mountain. It is the branch of Zhang River and meets the mainland.

"Where can we draw water from?" Lu Zhi asked.
