The next morning, the Engineer Brigade had already started the operation.

Behind them were almost all the artillery soldiers from the siege, covering them and guarding the soldiers in the city to leave the city to fight back.

At such a long distance, there is no need to worry about the bronze cannons on the city being able to hit the engineers.

An infantry division was deployed behind the engineer's side to guard against counterattacks in the city, and a cavalry brigade was also on standby around.

The engineer brigade in Si Shang was established very early, and was the "preparatory scholar" who guarded the city in the Mozi era. There were many people from Zhaodi, Zhongshan and other places.

The initial composition of the "preparing acupuncturers" was mainly composed of some well-digging craftsmen in Song, Wei, Qi, Lu and other regions. They followed Mozi and used their own ancestral craftsmanship as the source of many techniques in Mozi's "preparing acupuncture".

Wells appeared very early in Zhuxia. The special impact plain terrain in the Central Plains made well digging a very technical business: if you can't dig it well, it will cause collapse and suffocate in the well, so those who can dig wells in the Central Plains have certain skills.

After Mo Zi passed away, he formed a special engineer based on the preparation of cavemen, including some of his disciples; old miners summoned from Daye Mountain, Lingyang and other places; and some young people from tomb robbers in Zhongshan, Zhao and other places.

Later generations of Taishi said: Zhongshan is weak, and there are still people in the remnants of the sand dukes and mistresses. The folk customs are urgent and they rely on the opportunity to eat. When the husbands gather together, they are generous in their tragedy. When they rise, they follow the slogans. When they stop, they dig up the tomb and make clever and treacherous things. They are very beautiful, and they are very good at advancing...

Tai Shigong meant that people near Xingtai and Shijiazhuang farmed during the busy farming period, robbed and killed people in slack farming, and robbed tombs at night...

There was also a regional feature at this time, because there were frequent wars there, and the Shang Dynasty had many cemeteries as palaces and cemeteries, and the grassroots were basically in a state of unattended jurisdiction.

There is also an important road for horse trade in the north and a transit station for trade between the north and the Central Plains, so people there gather together to rob and kill people during the day, and they rob and dig graves at night to make a fortune.

This is an industry that has emerged since the Spring and Autumn Period. The Mohist family opposes a burial of burial; tomb robbers are in line with the times. Aren’t you a burial of burial? I will dig a grave to get rich.

Speaking of the tomb robbers, the people who robbed the tomb are actually very inconsistent with the Mohist school: if they are all burials, how can the tomb robbers get rich?

There have also been many conflicts between the two sides.

Later, the Mohist family began to go north to Zhao and penetrate Zhongshan. Gradually, many people joined the Mohist family and joined the engineering troops.

With well digging, miners and tomb robbers as technical backbones, the Engineer Brigade helped Si Shang win many siege battles. For example, the several sieges in the Qi-Mo War were the leading forces of the Engineer Brigade.

There were also many people who participated in the battle of the King of Chu to pacify Prince Chen and Cai, and many of them were veterans who served over the age and were very skilled.

Several old engineers were chewing on betel nuts transported from the South China Sea area, and leisurely took various tools for digging wells, robbing tombs and mining, waiting for the comrades in front to build a shelter.

The engineers in front used wicker baskets to fill soil. After the infantry behind them came, they used wicker baskets to build up a bunker, which was extremely thick. Even if the blind cat on the city wall hit a dead mouse, the iron bullet would not hurt the person digging the pit behind them.

Every about five steps, an experienced engineer was preparing to dig a pit. The 1,500 engineers in the engineering brigade were divided into three shifts, five hundred people per shift, each shift was dug for an hour, and then shifts were replaced day and night.

After the willow baskets in front were piled up, the engineers who had dug up many square meters of soil, dug through camp trenches, dug through crypt passages, dug through graves, dug through wells, mines, and canals began to work.

They stood behind the wicker basket and quickly dug out a pit for their body, aiming at the position of their companions five steps according to the white line set by the staff before.

The staff members need to calculate the distance from the city wall and the height of the city wall to determine the depth is enough to avoid the lead and iron bombs shot from the city head. However, these old engineers do not need the staff members to have triangular and computational drawings. They only need to set their eyes to know how deep they should be dug so far.

The shovels flew very fast in the hands of these old diggers, and the soil was swelling, but they did not splash everywhere, but were all loaded into the willow basket carried by the comrades behind them.

The company commanders are responsible for using simple protractors to deploy the angle of digging holes according to the brigade-level orders, so as to ensure that the cannons on the front of the city cannot hit the trench and cause longitudinal damage; they can also approach the city with the most effort and earth-saving approach.

A high-load work within an hour requires a lot of energy, and these engineers are treated very well. In addition to normal military rations, they can also have half a kilo of fat as a supplement every day.

At the southernmost trench opposite the city gate on the east side, a veteran who had been an engineer for twelve years outside digging calmly and quickly, digging while chatting with several new recruits behind him and teaching experience.

With his experience, as long as you dig well and dig according to the above requirements, there will be no casualties.

If the people in the city had the confidence to fight in the field, these engineers would not dig zigzag trenches, but would instead deploy artillery positions behind the buttocks of the artillery soldiers.

The veteran was also interesting. While digging, he joked with the new engineer behind him: "Tsk tsk, look, the most elite First Division in Si Shang squats behind us to protect us; the artillery that we spend the most money also protects us. These two most elite troops in the world protect us. Is this still small face?"

The few new recruits behind laughed, and the veteran spitted into his palms and said, "When you dig, you must be able to use your strength, and you cannot dig randomly. If you dig randomly, your arms will become sore after digging for a while, and you will not be able to survive."

"You have to dig like this..."

While speaking, he made several demonstration actions under the shadow of the wicker basket. These seemingly ordinary actions were the experience of those who were professional digging pits, and they could only be passed on by example and by example.

With one team as a group, the veterans only dig one position, and then the other four people have to widen the pit dug out by the veterans to one and a half steps.

After widening, the infantry or second-line soldiers enter and continue to widen to four steps, which is about six meters.

In addition to widening, the infantry behind also needed to use firewood and wicker baskets to place the filled soil outside the trench to prevent bombardment from the city head.

Veterans are experienced. In one hour, they only need to dig a trench of about four steps. The soil here is very soft and time is really surplus.

He was not in a hurry, and he had already passed the era of "competing" for young people. Although he would not fall behind, he would not be too successful.

There are a few young people in the company who are very active. They are busy during exercises on weekdays. Others can dig two steps.

The veterans also knew that it was worthy of praise, so they naturally would not think that those people were arrogant. If they were not arrogant in the Si Shang army, they would really have no capital to settle down.

But no matter how much he appreciates, the veteran would not do that because he is too tired. He never does it less. If he really gives orders, he will do his best to complete it. But today, if he digs four steps in one hour, it is really too easy, so he doesn't fight or chase, saving a lot of effort.

Twelve years ago, he was a young man who was beneficial to the world. Now he only regarded being a engineer as a job: no different from farming or weaving. Anyway, he served for nine years and paid a lot of money every year, so it was not a problem to marry and have children.

In his opinion, this is the important point that Si Shang will benefit the world in the end. If you rely solely on benefiting the world and have the ideal and enthusiasm to aspire to the world, you are afraid that the Mo family will have less than half of the people.

But in theory, he felt that he had also put in the power he should have and the order he should have executed. He still benefited the world, but he was a little behind others, and was still better than those nobles.

Many veterans in the army who served over the age are purely beneficial to the world, and some are used to life in the army and do not want to leave as a profession. The veterans who are digging pits are the latter.

The old engineer was extremely accurate in his hands. While chatting, he also asked the new recruits to come up and try it out.

Finally, I raised a ruler in my waist pocket, squinted my eyes and looked at the leveling level, and then leveled a few shovels. As soon as I put the ruler back to my waist, the whistle of changing shifts sounded, and the time was almost no shortage.

After returning to the back and handing over the widened trench, their company rested behind a slope and spread out on the spot. The cooks brought coarse tea with sugar and salt.

The old engineer raised the pot and poured it into half of his stomach. He took out a piece of brown sugar from his arms and threw it into his mouth. He had two hours to change shifts, so he could take the opportunity to sleep for a while.

The young people in the womb all went to listen to the company representatives telling stories. The veteran took off his hat and covered his face to cover the dazzling sunshine, thinking about the child's schooling.

Before the war started, I received a letter from my family saying that my child failed to pass the education level and did not meet the mandatory requirement of 200 words. Not only did my family be called to the township school and scolded him, but he also fined twenty yuan.

Thinking of this, the veteran smiled bitterly. This was not the first time. He subconsciously touched the belt distributed by the over-age service tied around his waist, thinking about whether to go back and let his son taste the feeling of the belt twitching buttocks. However, whenever he went back, he couldn't do it when he saw the child, and he just cursed for a few words.

"This time, you can't let it go! But this child really doesn't like to study and has to make a way. Xizi was transferred to the South China Sea to build a city, but it really doesn't work. When he finishes his service, he will go to the South China Sea to explore."

While thinking about it, a few cannons came from the city wall in the distance.

The recruits who had been listening to stories in the company representatives before stood up and looked at their partners who were digging in the distance, wondering if they were injured.

The old engineer was too lazy to get up, and even the sound of the cannon did not stop his thinking at all, as if he hadn't heard it at all.

Several new recruits hurriedly came back and surrounded him and said, "Sima Chang, did you hear it? There was a fire in the city."

The veteran grabbed the hat covered with his face and waved his hand and said, "If you should listen to the story, drink water, and sniff for a while. The pit I dug, let alone seven or eight cannons in the city, even seven or eighty cannons are fine. Go and go..."
