The fire dragon of the Ming Dynasty was the first in the world*, in addition, the coastal people and the Qi family army also made a lot of underwater bombs = bombs to fight against the Japanese invaders.

They carried them in containers such as jars*, sank into the water with fishing cages, covered the whole water, and detonated, but any Japanese ship that came close to the water would be blown up and sunk!

Xiang Mu and Shi Chongsheng are the most important technical forces of the new camp of Shenji, and they are the two masters who turned Li Mi's whimsical ideas into reality.

It's not uncommon for such a character to be able to create underwater bombs = bombs.

Although there is an underwater bomb = bomb, but the Forbidden City waterway system is very complex and huge, and communicate with each other, mutual influence, if the blasting site is selected properly, it can be drained and discharged, and the waterlogging ocean is completely emptied, but if the wrong place is chosen, it is very likely to affect the drainage of the palace and even the entire city!

After all, this is the old drawings left by Yongle Nian, after the changes of the times, although the preservation is complete, the picture is clear, but a large number of craftsmen's special symbols, it still took Xiang Mu and Shi Chongsheng a lot of effort to interpret them one by one.

The wisdom of the ancient people is full of spirituality, and all walks of life have their own exclusive codes or codes, especially craftsmen and craftsmen, these technologies are different from others, higher than others.

Coupled with the view of the portal, the technology is not easy to spread, so there will gradually be a lot of various symbols and codes in the industry that only people in the industry can decipher.

Especially the craftsmen, their symbols are more complicated and professional, and even the size and the like are replaced by special symbols.

This waterway diagram uses the technique of boundary painting, the pattern is square, the lines are extremely straight and clear, and there is not much difference from the design drawings of later generations.

By the way, as I said earlier, boundary painting is a very distinctive category of Chinese painting, because it uses the boundary ruler as a guideline, so it is called boundary painting, which is generally used to depict architecture, which is extremely accurate and subtle, and is similar to the design renderings of later generations.

Xu Guangqi had already taken a big risk by smuggling this waterway map out, and everyone didn't dare to delay any longer, so Li Mi immediately said to Suo Changsheng.

"You go to the Armory Bureau prison, pick a few troublemakers, and bring them to me, you should know what to look for, right?"

Seeing this situation, Suo Changsheng already knew Li Mi's plan, and of course he knew what kind of person to find.

These thugs occupy the underground sewers as their nests, evade the government, and specialize in some shady deeds, and even open a black market in the underground sewers, where many prohibited items can be bought, and the black market also undertakes all kinds of dirty transactions such as revenge and assassination.

They were people who knew more about underground waterways than architects, and if it weren't for that, Li Mi wouldn't have taken care of them all and arrested them all.

This is also a good strategy to kill two birds with one stone, which not only crushes Zheng Guifei and Zhu Changxun's coercion and drive away Li Mi, but also allows these thugs to play the greatest role and let them do something beneficial to the people.

Of course, letting them do these things at this time is actually the biggest punishment for them.

After all, these troublemakers are not outlaws, people who are greedy for life and afraid of death will do these shameless things to bully the weak and afraid of the hard, the real outlaws are always killed with a knife, either you die or I live, what they are eager to do is to fight with stronger people, and they don't have much interest in the weak.

It is precisely for this reason that carrying underwater bombs on their backs and entering underground waterways that may flood their lives at any time is naturally the greatest punishment for them.

Suo Changsheng's eyes were also very vicious, and after a while, he picked out all the leaders in the mash and brought them to Li Mi.

Storming the Ordnance Bureau is a capital offense, and these troublemakers have long been stupid.

If it is said that the Ordnance Bureau arrested Li Mi, they would have some confidence, because Zheng Guifei and Zhu Changxun would fish them out sooner or later.

However, at this time, Li Mi stayed with the leaders of the Ordnance Bureau, and he could interrogate them at will, and the troublemakers fell into despair.

Observing words and judging the situation is the survival wisdom they rely on the most, without these two abilities, they would not be able to survive in the underworld so far.

The so-called people who know the times are Junjie, these people don't have any discipline, where do they need Li Mi to threaten them, they just kneel down and ask for mercy.

"Don't kneel, it's useless to smash your brains, where the Ordnance Bureau is, you should be clear, even if this official cuts off your heads now, no one will ask for half a word, you don't have a choice at all."

An old man like Xiang Mu is well versed in people's hearts, and he immediately extinguished all the hopes of these pounds, and only by forcing them into a desperate situation will these pounds accept such a task.

"You don't have any luck thoughts, these are the fans of Dongchang, what is the situation in your family, you can find out before dawn, you will die if you want to die, but Mo Lian's family is it."

Shi Chongsheng was even darker than Xiang Mu, and when these words came out, the troublemakers finally lowered their heads.

"Ladies and gentlemen, it's not that I don't want to wait, it's just that if I go in, I can only die, and now the city is full of oceans, and there are not many routes left in the waterway, not to mention, the thing in the waterway is ......."

"That thing is the living Hades, if it weren't for that thing, why would we go to the ground and walk around......

"Living Hades?" Li Mi was also puzzled when he heard this word, in fact, he had already noticed that these pounders were no longer active underground before the rainstorm came.

At first, Li Mi only thought that it was Zheng Guifei and Zhu Changxun who recruited these underworld forces, but he didn't expect that there was another reason for it!

"Yes, Master Li, I won't tell you, we people, that is not visible, the underground waterway is our paradise, it is the place where we eat together, if that thing does not occupy the waterway, how can we turn to the ground?"

When everyone heard this, they didn't believe it, and most of them thought it was an excuse for these troublemakers, but Li Mi was convinced!

"Don't worry, I'll go in with you, and I'll take care of that thing, and now, I need you to put it all together, and it's better to blast it there."

"You are cockroaches and rats in the waterways, this is not to scold you, but to praise you, no one knows the underground better than you, blowing up part of the waterways, enhancing the excretion capacity, is for the benefit of the entire Jingshi people."

"If you don't do it, the city is like a sea, your family is also suffering, and you have done so many things that are sorry for the neighbors, and you don't want to repay these neighbors this time?"

"I know your heart is not bad, it's just to eat for a while, and it won't be so vicious as to hurt people's lives, now is your best chance, doing this thing, it can be regarded as accumulating yin virtue, and after death, you won't be beaten down to the eighteenth layer of hell, this is a good thing, you should have rushed to do it, didn't you?"

As soon as Li Mi said this, the troublemakers also fell silent.

In their opinion, entering the waterway at this time is simply a long life for the birthday star to eat arsenic, but what Li Mi said is exactly what they are talking about.

They are not traitors in the end, but whenever they have the opportunity to reform themselves, they will inevitably change their minds, not to mention, Li Secret is the former Zuodu Imperial History, the Count of Martial Arts, for the sake of the people, he is willing to follow them into the waterway, where do the troublemakers have something to say?

However, Zhen Mi and the others were anxious: "You want to go in with them?" ”

Li Mi nodded and said to everyone: "No one knows the Living Yama King better than me, and this matter must be done by me." ”

As soon as Li Mi said this, Zhen Mi and the others also suddenly realized, because they finally knew what the Living Yama King was referring to!

Sarufei Sasuke and Abe Genkai joined halfway after all, and they didn't know much about this thing, so when they saw that everyone was worried, they said to Li Mi: "Your Excellency, the two of us are willing to accompany you!" ”

Li Mi looked at Sarufei Sasuke, then at Abe Genkai, and immediately nodded: "It's okay, you guys can follow." ”

He has seen Abe Genkai summoning gods, although he doesn't know whether it's true or not, but it can come in handy at a critical moment.

After this decision, the pounders also knew that there was no way back, so they put their minds on the waterway boundary painting, and thanks to the fact that the waterway had not changed for a hundred years, they quickly found a suitable position.

After Xiang Mu and Shi Chongsheng's consideration, Xu Guangqi and Matteo Ricci calculated the drainage capacity, and then it was decided.

The people of the Ordnance Bureau brought out all the underwater explosive = bombs that had been successfully developed, equipped them properly, and used sealed canisters and other materials to save the fire, and then sent Li Mi and others out.

Li Mi is also racing against time, after all, if you stay for one more day, the people will suffer from the flood for one more day.

There is no need to look for the entrance to the waterway, a place like the Ordnance Bureau, full of workshops, with the largest drainage, and the entrance and waterway are also the most spacious, even if you walk through the underground entrance of the Ordnance Bureau.

This was the first time Li Mi had entered the underground drainage system of the Forbidden City.

The underground drainage system of the Forbidden City came from Kuai Xiang, a super craftsman who was also the designer and builder of Nanjing City, and Kuai Xiang, who was born in the Xiangshan Gang, was the best at drainage systems.

Even in later generations, with the use of advanced science and technology to investigate and detect, the drainage system of the Forbidden City can only be explored to explore the structure of open channels and culverts, and the drainage system cannot be fully mastered.

In other words, it took hundreds of years for later generations to study the underground drainage system of the Forbidden City, and no one knows what is inside.

The imperial city is heavy, the residence of the Son of Heaven, is not an ordinary place can be compared, if even the imperial city is waterlogged, the craftsmen have to come to see it, so when designing and building, the admiral and the craftsmen are all trembling and doing their best.

In later generations, the Forbidden City has never had a large-scale water accumulation, but Wanli has experienced a lot of palace fires, and when the craftsmen repair the palace, it is inevitable that there will be some changes, some waste materials, etc., will be filled under the foundation, blocking part of the waterway, and there will be water accumulation.

Moreover, the capital and the imperial city are not the same concept, the imperial city does not accumulate water, it does not mean that the capital does not accumulate water, and the drainage system of the outer city is not connected to the imperial city.

What Li Mi has to do this time is to use the mysterious drainage system of the Forbidden City to drain the stagnant water in the outer city!

This kind of adventure experience is not something that anyone can bump into, at this time the ground is too wet, the water is up to the waist, and the water is turbulent, if it is not for everyone to tie it up with ropes, and connect to the safety rope, I am afraid that it will be washed away!

However, the troublemakers were familiar with the way, and after a while, they took Li Mi to the shallow main road and continued to walk forward.
