Chapter 7 No man can resist an excavator, including Erfeng
After the release of Li Shimin's mission, Tianmu entered into a fierce competition among players.
After all, in modern China, there are countless high-end engineering teams, and it is difficult not to be involuted.
Our engineering team has large shield drones, unmanned surveying drones, and the latest high-tech automatic excavators...
What's that? How many subway lines have you dug? Are there any AI-powered excavation robot dogs or robots?
[Erfeng, it's okay if you don't understand. This is how modern engineering bidding works. The competition is fierce.]
It seems that future generations can really dig two tunnels within half a day?
In this case, Li Shimin immediately told Cheng Qianli and others about his night attack plan. After hearing it, Cheng Qianli slapped his thigh and exclaimed that this plan was brilliant.
"I didn't expect that you, the Prince, are so foresighted that you've already dug a tunnel and are waiting for us!
Who among the enemy could have imagined that you had dug a tunnel in Chang'an before? "
Their prince is truly amazing, he is simply the modern Zhuge Liang!
Hearing such flattery and praise, Li Shimin touched his chin:
"The tunnel... is being prepared for digging now."
Cheng Qianli and Gao Shi: ???
"Although we are just preparing to dig, it is said that it can be completed in half a day." Li Shimin continued to add.
Cheng Qianli was stunned. Gao Shi opened his mouth and forgot to close it for a moment. He asked in surprise:
"Prince, how many craftsmen did you hire? This...it's impossible without tens of thousands of laborers."
"Ahem," Li Shimin said a little embarrassedly. After all, he could only invite three people at most for each mission he issued.
"Anyway, they should be here by now. Just treat them as people from overseas and don't be too surprised when you see them."
As Li Shimin was speaking, a soldier suddenly came hurriedly to report that the enemy had used a huge weapon to attack the city!
Cheng Qianli and the others immediately rushed out with their Mo Daos. Then they saw several huge four-wheeled vehicles not far away, moving forward and backward on their own.
“This, this, this…”
Having never seen anything like this, all the soldiers and generals were shocked and drew their swords to prepare for attack.
Li Shimin quickly stepped forward and explained to everyone that this was a craftsman he had hired. Everyone then breathed a sigh of relief.
The Blue Sky Engineering team, trapped in the middle, panicked as they watched the other side raise their swords and knives. Only when they saw Li Shimin coming out to rescue them did they dare to jump off the excavator.
At this time, the engineering team leader Li Feng ran forward excitedly and tried to shake Li Shimin's hand.
However, as soon as he stretched out his hand, the two generals opposite him glared at him as if they were going to chop his hand off. He could only give up in frustration and quickly introduced himself:
"Don't be afraid, everyone. This is the detector excavator and shield machine we use for excavation."
"What... stewed chicken? General Gao, you're so knowledgeable, have you ever heard of this?"
In response to Cheng Qianli's question, Gao Shi shook his head with a confused look on his face.
Could three weird people really dig a tunnel in half a day?
"That depends on how long and deep you want to dig. You need a rough plan first, then I can make a judgment."
Li Shimin thought for a moment and then said:
"It would be best to dig a line in each of the east and west corners of Chang'an City, but of course, just one line is also fine. As for the length, dig three and a half miles in a straight line from the corner of the city, and a depth of about ten feet will be enough."
"Only five meters! So shallow?"
The experienced Li Feng couldn't help but blurt out.
Li Shimin: ………?
[Hahaha, the construction team was shocked. They've probably never dug such a shallow tunnel in their lives.]
"We've even brought a tunnel boring machine. This thing can go a hundred meters underground. Digging a five-meter tunnel is like using a nuclear bomb to kill a mosquito."
"Of course five meters is fine too. It's faster."
After hearing this, Li Feng felt that it was not difficult at all, so he continued to ask:
"What about the width and height of the tunnel?"
"As long as it can accommodate one cavalryman and one horse, and is about five feet high and three feet wide, it will be fine."
"No, no, this width is too narrow!
Our machine can’t dig out something this narrow; it has to be at least two meters wide.” Li Feng refused outright.
After all, their excavators have to dig a tunnel with a width of 1.5 meters. It is impossible for such a large excavator and shield machine to dig a tunnel that is less than one meter wide!
Li Shimin: ………
"Then just do as you say, it seems you have it all planned out.
Can two tunnels really be dug in half a day?"
"Don't worry, Your Majesty... cough cough"
Li Feng almost called out "Your Majesty" but was slapped on the back by the engineer behind him. Then he realized it and quickly changed his address:
"Er Feng, just wait and see. Our engineering team's quality is top-notch! We participated in the construction of the Three Gorges Dam!"
"That's right, we still need to find someone to help move the soil."
Li Shimin immediately ordered his men to find the civilians. Meanwhile, Cheng Qianli and Gao Shi did not leave either.
Because they were also very curious and were planning to see what was so magical about this stewed chicken.
Soon, Zhao Junkai, an engineer from the engineering team, took a detector with a screen and began to survey the underground situation near the corner of Chang'an City.
[I've never seen a tunnel being dug before. Click here to watch the live broadcast of the tunnel being dug in Chang'an.]
[This is really interesting. I've never seen a tunnel boring machine before. It's so huge, I was shocked.]
So what are you doing now? Why aren't you digging yet?
[You're so uneducated! Before digging a tunnel to build a subway, you have to survey the geology first. What if you hit a collapsed layer?]
[This is to explore the underground soil quality and whether there is hard rock, etc. Finding the right location will achieve twice the result with half the effort.]
So that's how it is.
Li Shimin finally understood after reading the explanation on the sky curtain.
I didn’t expect that China would change so rapidly a thousand years later and would be completely different from the Tang Dynasty.
After Zhao Junkai measured and found the correct position, operator Wang Jianguo directly operated the AI intelligent shield machine.
The shield machine is actually a tunnel boring machine using the shield method, that is, the arc-shaped tunnel boring machine digs a passage in the front and lays cement in the back at the same time.
In order to avoid disturbing people, today's shield machines make very little noise, and the excavated material will not sink, which is very advanced.
After the shield machine started digging by itself, Cheng Qianli, Li Shimin and others were a little confused.
Li Shimin looked at these three people standing outside, not going down, and asked in surprise:
"You guys are just...standing like this?"
At this point, Wang Jianguo, who was in charge of engineering operations, chuckled and pointed to the tablet interface in his hand:
"We now use AI, or artificial intelligence, instead of humans. The machines will plan the best route and then dig and lay it themselves."
Digging tunnels was easy in ancient times, but in modern cities, we have to worry about electrical wires, optical cables, sewers, etc., and we have to be very careful.
Ancient Chang'an was different. You just had to push forward and it was so fast.
Although they didn't quite understand what was said, Li Shimin, Cheng Qianli and the others were all amazed at the paved hole, which was filled with something called cement, which was very solid.
At this time, after the digging in front was completed, the soil had to be transported out. Li Feng walked onto an excavator and began to dig out the soil in the hole and transported it to the side to dump it, which made many soldiers nearby couldn't help but look over.
Even Li Shimin was staring intently at the excavator and could hardly take his eyes off it.
[Hahaha, I knew no man could resist an excavator, including Li Shimin!]
[As a modern person, I was fascinated by it and even wanted to try it!]
Not only modern people, but Li Shimin would have wanted to go up and try it if there wasn't a tough battle at night.
Cheng Qianli didn't have so many concerns. He watched the excavator with his eyes shining, eager to try:
"It looks quite easy. This thing would be great to use on the battlefield. Warrior, let me learn it and use it on the battlefield."
Li Feng had actually thought about it at first, but he soon realized that the permission was limited to this mission, and immediately shook his head with some regret:
"No. I don't have enough authority."
Things that were so far ahead of their time were bound to have limitations in their use. Li Shimin had anticipated this and did not regret it.
Moreover, if we rely too much on these equipment that are difficult to produce in the Tang Dynasty, I am afraid that it will only make future generations more lax, which is not a good thing.
As they were talking, a tunnel had been dug halfway. Li Shimin and a few others went down to take a look and saw that the tunnel was paved very solidly and spaciously, far exceeding their expectations for temporary use.
“This is truly amazing!
The technology you will have a thousand years from now is truly unimaginable to the world."
Li Shimin could not help but sigh deeply, which made Li Feng beside him proud. He immediately said:
"That's nothing. We even participated in the construction of the Three Gorges Dam back then.
Your Majesty, you know that we built a dam over 100 to 200 meters high upstream of the Three Gorges. It can not only prevent floods and discharge water, but also carry out water transportation and power generation, and it can also transfer water from the south to the north for use."
Li Shimin only imagined such a huge project in his mind, and he became more and more curious about the modern situation of China.
"But what if such a conspicuous project is destroyed by the enemy?"
[Don't worry, how could this happen... Are you looking for death?]
The Three Gorges Dam is equipped with an anti-missile system. If he dares to launch a missile, we can intercept it with a missile, or send a Dongfeng Express to send him a giant mushroom.
It sounds like China will have a high status among its neighboring countries in the future?
"That sounds great. It's far better than our Tang Dynasty."
[Alas, we can't compare to Er Feng back then. We're still on the road to national rejuvenation.]
[Yes, yes, the goal of our national rejuvenation is the glory of the Tang and Han dynasties!
We haven't achieved the goal of all nations wearing formal attire and paying homage to the emperor yet.
Although these descendants sometimes speak boldly, they are humble and lovable.
While Li Shimin and Tianmu were chatting, the tunnel had already been built about 70% to 80%.
It was already late at night and everyone had just finished dinner when they suddenly heard the sound of horns and loud noises outside the city.
As Li Shimin had expected, An Qingxu had already led an army of 100,000 to attack the city.
And that loud noise was the earth-shaking sound when the rebels' battering ram crashed into the Chang'an city gate.
In the Tang Dynasty, sieges were mainly carried out using tools such as battering rams, ladders, catapults, and rockets.
In order to capture the capital Chang'an as soon as possible, An Qingxu even built a siege tower not far from the Chang'an city wall.
Fortunately, Chang'an is the capital after all, and the city walls are maintained every year. The quality is better than other places, so it is not so easy to be breached.
What's more, the soldiers defending the city were well organized under Li Shimin's arrangement. They used water and soil to extinguish the rockets, and those climbing the ladders threw stones and kerosene to smash them down.
As for the siege tower that the enemy had spent a lot of time building, Li Shimin drew his bow and shot the flaming arrow from a distance.
In the night sky, the rocket landed on the wooden tower as accurately as a meteor, quickly igniting a fire and causing the siege tower to collapse.
But after all, the circumference of Chang'an City's walls was too large and there were not enough soldiers. If we just kept defending it like this, there would inevitably be casualties.
Therefore, if a sneak attack can be launched at this time, the offensive and defensive situation will change quickly.
[Is the tunnel ready? When will we launch the counterattack? I'm so anxious!]
Not to mention that the audience on the sky screen were anxious, Cheng Qianli also ran up and down the city wall several times.
Just as the two sides were attacking and defending the city, Li Feng from the engineering team finally came out of the tunnel and said:
"Both tunnels have been repaired and can be used now."
