To export infrastructure, we must also consider the international environment, road conditions, the country's public security, and a few years of infrastructure. If the national security is not good, it will be very troublesome to change a monarch in the middle.

Therefore, to maintain the safety of workers who go abroad, the Song Dynasty army must be strong, and the Mohist family must have a certain influence abroad to prevent other countries from owing debts and avoid bad incidents of kidnapping workers. In the Spring and Autumn Period, the population was national strength, and the skilled population was even more powerful for the king to salivate.

Population is power, so when fighting, all the population of the failed country is often moved away. If the workers of the Song State go abroad, they will be moved gold, and they will inevitably be intercepted by other countries and take it for themselves. Therefore, many issues need to be considered and further improved.

Anyway, we don’t have to go abroad now. We are currently carrying out infrastructure construction in the country of Song to demonstrate the strength of the Mohist family. But without large machines, we rely entirely on manpower, it is obviously very hard-working, so we need machinery.

The manufacturing of machinery naturally requires power sources. Yunyao batches provide the Mohist with real fire-driven steam engines, without digging coal, and is environmentally friendly and safe.

With the real fire steam engine, the Mohist family can produce various mechanical investment projects, build bridges and open mountains when encountering water, and directly bring a set of infrastructure packages to the State of Song. From water conservancy to transportation, it is well done. No matter which country's envoy comes, it will say it is good.

With transportation and water conservancy, it can radiate to the surrounding areas and drive economic development.

When Yunyao met Mozi, he was only 30 years old and very young, and could do a lot of things. Now, Mozi, who is forty, thought that after he had an agency, he could continue to promote non-aggression. Wherever there was an unjust war, he could stop it.

But Mo Zi would not have thought that a person who had been forgotten had returned to Chu after years of hard study, and brought back seven siege machines produced using technology. These were Luban No. 1 to No. 7.

As soon as Lu Ban returned to Chu, he inquired about the situation of Song and learned that Song had relied on the Mohist mechanisms for a few years after he left, and had become a powerful infrastructure country.

This is a good thing. In this way, Chu State will make a profit by capturing Song State. In order to compete for the title of the world's number one skilled craftsman, the first thing Lu Ban did when he returned to Chu was to persuade the Chu army to send troops to attack Song State.

Lu Ban is full of confidence. As long as he relies on his Lu Ban No. 1 to Lu Ban No. 7, there is no unbreakable city in the world. This is the crystallization of his many years of studying in Zhucheng. In recent years, he has only slept for two hours every day and started to learn as soon as he opened his eyes. In order to master the most advanced mechanism technology, he worked hard and endured all the hardships, but he persisted in all these. Now he will defeat Mo Di and conquer the State of Song.

Now the Mohist family has radiated outward with the State of Song as the core, insisting on joining together craftsmen, farmers, savages, and small nobles, and the four-unionist proposals of joining the country, and the people of Mo are spread all over the world. The people of Mo in the Chu State also have Mo, so whenever there is any movement in Lu Ban, the people of Mo immediately pass the news back to the giants.

"Lu Ban convinced Chu to assemble a large army to attack Song?" The giant frowned when he saw the information. After thinking for a long time, he remembered that Lu Ban had asked him to practice skills, but they were all verbally saying that he could create a mechanical bird that could fly for three days and three nights. He didn't know whether it was true or false.

"It's better to send the Mohist to find out whether the information is true as soon as possible." Taoist Lingbao reminded.

"That's true. Lu Ban is also a skilled craftsman. Suddenly instigating the Chu army to start a war, he must have made some special preparations, and he must also check what kind of siege equipment he made." The giant said: "Immediately send the Mo people of Chu to investigate clearly, and at the same time send the Mo people of Song to prepare for defending the city."

The war of life and death has not yet begun, and the intelligence war has begun. "The Art of War" uses a chapter, which is to use spies. By the end of the Spring and Autumn Period, it was already very common.

Through the investigation of the Mozhes in Chu, it was found that Lu Ban really mastered the amazing mechanisms, with seven of them in total. They investigated five of them. The first mechanism was a huge catapult car that could throw a thousand kilograms of stones and defeat the city wall.

The second mechanism is a digging truck, which can quickly dig out tunnels and attack them unpredictable.

The third mechanism is the iron-clad door-to-door car, all surrounded by iron-clad bows and arrows, and boiling water and hot oil.

The fourth mechanism is Feitian Wing, which can fly over the city wall without a ladder and send soldiers to the city.

The fifth mechanism is an arrow stopper. If a bow and arrow attack, the arrow stopper can block all the arrows.

Lu Ban No. 6 and Lu Ban No. 7 are the most mysterious. There is no intelligence yet. Lu Ban has not made any demonstrations in Chu State. It is just mentioned in front of Chu Jun. However, Lu Ban also said that as long as the first five institutions are enough to defeat the Mo family and capture the Song State.

Chu Jun did have 100% trust in Lu Ban's technology. It can be said that no king could be unhappy after seeing Lu Ban's engineering equipment. Before these giants, the city walls were nothing but native chickens and tiles, not worth mentioning.

Holding a weapon in your hand, the murderous intention arises.

Faced with the aggressive attitude of Chu State, the Mo family gathered together to discuss the method of defending the city. The Mo people had not been so nervous for a long time.

When everyone saw the catapults, digging trucks, hitting door trucks, flying wings, and blocking arrow trucks on the intelligence, they were all thinking hard to find a countermeasure to deal with these things. In particular, the digging truck reminded the Mo people of the disastrous defeat of Qi. At that time, the Chu State used authentic methods to cross the city walls and conquered the city gate.

Now the Chu State's siege is becoming more and more powerful, but the Mo family seems to have not even solved the authentic problem.

A few years ago, the most troublesome thing for the Mohist school was two things. One was the Taoist's stubborn proposal, and the other was the method of cracking down on the Tao. The previous one had been solved. The Mohist school proposed to be close to the world. Now even Taoist priests and Confucian scholars are willing to join the Mohist, because in the Mohist school they can retain their identities as Taoist priests and Confucian scholars at the same time, and they do not need to completely give up their ideas and opinions. As long as they are willing to work hard for peace in the world with the Mohist, then everyone is Mohist.

But I never expected the second method to crack the authentic one. Of course, it was because the Mohist was mainly engaged in infrastructure construction in the Song State in recent years and didn't care much about thinking about the tactics of defending the city.

However, it was impossible to solve the problem before, which does not mean that there is no way now. After several years of infrastructure construction, the Mohist school has accumulated a lot of engineering experience, and some Mohists have suggested that they can use sound to explore the tunnel.

"When I was doing the project, I found that if there were organs operating in the distance, I could hear sounds through the ground by attaching my ears to the ground. Our eyes really couldn't see through the ground, but our ears could see the enemies underground. As long as we sent people to lie on the ground every day and listen to sounds."

"No need to lie down. I discovered a phenomenon before, that is, listening to the sound in the water tank will be clearer. So we only need to bury a large number of water tanks on the ground to find their diggers." The ink master gathered his mind and finally came up with a solution to crack the authenticity, which is to bury the water tank and listen to the sound.

As long as there is movement underground, the sound will reach the water tank and expand, and the enemy will be immediately ready to face it.
