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

Therefore, in order to maintain the safety of migrant workers abroad, the Song army must be strong, and the Mo family must also have a certain influence abroad, so as to prevent other countries from defaulting on their debts and there will be no bad incidents of kidnapping workers. In the Spring and Autumn Period, the population was the national strength, and the skilled population was the coveted power of the monarch.

Population is power, so when a war is fought, it is often the entire population of the failed country that is relocated. If the workers of the Song Kingdom went abroad, it would be moving gold, and it would inevitably be intercepted by other countries and taken for themselves. Therefore, many issues still need to be considered and further improved.

Anyway, it's not that I have to go abroad now, but at present, I am building infrastructure in the Song Kingdom to show the strength of the Mo family. But there are no large machines, it all depends on manpower, which is obviously very hard-working, so machinery is needed.

The manufacture of machinery naturally requires a power source, and Yunyao provides the Mojia with real fire-driven steam engines in batches, without digging coal, which is environmentally friendly and safe.

With the real fire steam engine, the Mo family can produce all kinds of machinery into the project, can meet the water to build bridges and mountains to open mountains, and directly gave the Song State a set of infrastructure packages, from water conservancy to transportation in order, no matter which country's envoy comes, he will say good.

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

When Yun Yao met Mozi, he was only thirty years old, very young, and he could do many things. Now the forty-year-old Mozi thinks that after having a mechanism, he can continue to promote non-offensive, and where there is an unjust war, he can stop it.

But Mozi would not have thought that a person who had been forgotten by him would return to the state of Chu after years of hard study, and at the same time bring back seven siege machines produced using technology, which were Luban No. 1 to No. 7.

As soon as Lu Ban returned to Chu State, he inquired about the situation of Song State, and knew that Song State had relied on Mojia machine skills to make a prosperous and impressive situation in the few years since he left, and it seemed to have become an infrastructure power.

This is a good thing, so that the Chu State will have a profit from the capture of the Song State, in order to compete for the title of the world's first craftsman, the first thing Lu Ban did when he returned to Chu was to persuade the Chu army to send troops to attack the Song State.

Lu Ban is full of confidence, as long as he relies on his seven organs from Luban No. 1 to Luban No. 7, there is no city in this world that cannot be attacked. This is the crystallization of his years of study in Zhucheng, in the past few years, he only slept for two hours every day, and began to study as soon as he opened his eyes, in order to master the most advanced organ technology, he worked hard and endured all the hardships, but he persevered in these, and now he is going to defeat Mo Zhai and capture the Song State.

Nowadays, the Mo family has radiated outward with the Song State as the core, and adhered to the four-joint proposition of uniting craftsmen, farmers, savages, and small nobles in various countries, and Mohists have spread all over all walks of life. There are also ink scholars in the Chu State, so as soon as Lu Ban makes a move, the ink scholars immediately send the news back to the giant.

"Lu Ban persuaded the State of Chu to gather a large army and prepare to make a move against the State of Song?" The giant frowned as soon as he saw the information, and thought for a long time before remembering that this Lu Ban had also asked him to learn skills back then, but it was all verbal, and he said that he could make a bird that could fly for three days and three nights, and he didn't know whether it was true or not.

"It's better to send the ink artist as soon as possible to find out if the information is true." Lingbao Daoist reminded.

"That's true, this Lu Ban is also a skilled craftsman, and he must have made some special preparations for suddenly instigating the Chu army to go to war, and we have to find out what siege equipment he made." Juzi said: "Immediately order the ink people of the Chu State to investigate clearly, and at the same time send an order to the ink people of the Song State to prepare to defend the city." ”

The war of life and death has not yet begun, and the intelligence war has already begun. "The Art of War" uses an intersection, that is, the use of spies, and by the end of the Spring and Autumn period, spies were already very common.

Through the investigation of the Chu Guomo, it was found that Lu Ban really mastered the great mechanism technique, there were seven in total, and they investigated five, the first mechanism was a huge catapult, which could throw thousands of catties of boulders and break the city wall.

The second trap is the Digger, which can quickly dig out tunnels and attack them unprepared.

The third mechanism is the iron door car, all surrounded by iron sheets, and there is nothing to be done about gravel bows and arrows, boiling water and hot oil.

The fourth mechanism is the Sky Wing, which allows you to fly over the walls without a ladder and drop soldiers into the city.

The fifth mechanism is the Arrow Car, which can stop all the arrows if a bow and arrow strikes.

Luban No. 6 and Luban No. 7 are the most mysterious, there is no information yet, and Luban has not made any show in Chu State, but only mentioned it in front of Chu Jun, but Lu Ban also said that as long as the first five organs are enough to break the Mo family and capture the Song State.

Chu Jun does have 100% trust in Lu Ban's technology, and it can be said that no monarch can not be impressed after seeing Lu Ban's engineering equipment. Before these behemoths, the city walls were nothing more than dirty chickens and dogs, not worth mentioning.

With the murder weapon in hand, the murderous intent arises.

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

When you see the catapults, digging trucks, door trucks, flying wings, and arrow trucks on the intelligence, they are all thinking hard and trying to find countermeasures to deal with these things. In particular, the earth digging truck reminded the ink scholars of the fiasco of the Qi State, when the Chu State used the method of tunnels to pass through the city wall and capture the city gate.

Now the siege weapons of the Chu State are getting stronger and stronger, but the Mo family doesn't even seem to have solved the authentic problem.

A few years ago, the biggest headache for the Mo family was two things, one was the Taoist idea, and the other was to crack the authentic method. The previous one has been resolved, the Mo family proposed to make friends in the world, and now even Taoist priests and Confucian scholars are willing to join the Mo people, because in the Mo family they can retain their identity as Taoist and Confucian scholars at the same time, and they do not need to completely give up their ideological ideas, as long as they are willing to work together with the Mo people for the peace of the world, then everyone is the Mo people.

But the second way to crack the tunnel has never been expected, of course, because in recent years, the ink has mainly engaged in infrastructure construction in the Song Kingdom, and has not cared too much about thinking about the tactics of defending the city.

However, it can't be solved before, it doesn't mean that there is no way now, after several years of infrastructure, the Mo family has accumulated a lot of engineering experience, and some ink people have proposed that they can use sound to explore the tunnel.

"When I was working on the project, I noticed that if there was a mechanism in operation in the distance, I could hear the sound through the ground by attaching my ears to the ground. It is true that our eyes cannot see through the ground, but our ears can see the enemy underground. As long as we send people to lie on the ground every day and listen to the sounds. ”

"I don't need to lie down, I found a phenomenon before, that is, listening to the sound in the water tank will be clearer. So we just need to bury a lot of water tanks in the ground and we can definitely find their diggers. "The inkman brainstormed and finally came up with a way to crack the tunnel, which was to bury the water tank and listen to the sound.

As soon as there is movement underground, the sound will reach the water tank and expand, so you can immediately detect the enemy and prepare to attack.

However, the giant knows that it is not enough, if this battle is to be fought, it is necessary to prepare a war mechanism, so as to stop the arrogant Lu Ban.
