The presence of another official official shows that Ding Kui is not afraid of the spread of the matter.

Wu Yi's plan is that the two militaries have dealings on the surface, and they do not carry private goods, and they are not afraid of making it public.

The battle to regain Zhongwangzhou is about to begin, and although Ding Kui does not think that the Qi State will harass the eastern border, it is very safe that there is a formal mechanism to control the border between the two countries, and he feels that it should be finalized as soon as possible.

Wu Yi's plan focuses on sending people to monitor the border army with each other, especially the Tongyuan River water army, as long as there is a large-scale military operation, there is no way to bypass the water army, and keeping an eye on the water army can get early warning, at least to ensure that it will not be attacked.

As for the harassment of small forces, there is such an agreement, and you are embarrassed to do it.

Both the Shaodian and Qi kingdoms had internal and external troubles, and the non-aggression agreement was beneficial to both countries, and Ding Kui was soon authorized to sign a formal agreement with Wu Yi the next day.

Wu Yi didn't stay long, and after getting the agreement, he left to return to Qi.

"General Qiqi, the track of the Xijiang Tunnel has been laid, and Master Qingyang has applied to immediately carry out the rocket rail car test. ”

"Accurate!" Ding Kui approved without even thinking about it.

The construction of the Xijiang Tunnel involved the labor of two states, and the construction of the north and south directions was started at the same time, so the progress of the project was rapid, and the railroad tracks were laid in less than two days.

The rocket rail car uses the Xijiang Tunnel as a pilot, which is the consensus reached between Ding Kui and the Magic Association.

The Xijiang Tunnel has a fixed length, a fixed terrain and a fixed environment, and basically has no interference factors, which is most suitable for the operation of rocket rail vehicles.

At Ding Kui's suggestion, the rocket orbiter was divided into single-section rockets and multi-section rockets.

As the name suggests, a single-stage rocket is a rocket that passes through the entire tunnel, which has the advantages of fast speed, low energy consumption and simple structure.

The disadvantage is that the initial kinetic energy is too large, and the load on the vehicle has to withstand a lot of pressure.

Living and fragile objects could not withstand excessive pressure and were not suitable for single-pitched rockets, so it was necessary to develop multi-pitched rockets.

The multi-section rocket is to ignite the rocket many times in the process of penetrating the tunnel, and the kinetic energy of the previous rocket is attenuated and the new rocket is used to provide kinetic energy until the rail car completes the passage, which has a large loading capacity and a wide range of applications.

The disadvantages are slow driving speed, high energy consumption, high failure rate, complex structure, etc., which require special personnel to monitor the situation of the rocket, and the cost is undoubtedly higher than that of a single rocket.

"A rocket brings a curved velocity change, and the regenerative rocket does not have to ignite when the orbital car stops, but can ignite when the speed decays to a certain point......"

Qingyang Zi and Kuai Lian discuss the test plan of the multi-section rocket.

The single-section rocket rail car has been finalized, divided into five cars, ten cars and fifteen cars, each rocket can pass through the Xijiang tunnel with one shot, but the carrying weight of the rail car has requirements, not too heavy nor too light.

The rail car that is too heavy will stop halfway through, and if it is too light, it will rush past the destination station.

"Oh, so I understand, it's actually very simple, just try a few more rocket models, make the rocket smaller, put more spare rockets in the tail, increase the braking force, and the multi-section rocket rail car can be more flexible. ”

Kuai Lian is not stupid, and he understands it when he hears it.

When Ding Kui returned to Shuiyan Town, the multi-section rocket orbital car was almost finalized.

"There is no need to test tomorrow, the manpower and livestock of the guards will pass through the tunnel first, and by the way, the track embankment will be tamped and the road will be opened for the army. "Ding Kui can't wait.

The equipment of the escort army is heavy, and there are more livestock used in the march, so there is no need to wait for the rocket car to be developed, and there is a track to pass, which is why Ding Kui transferred them first.

"It's okay, at the latest, the disciple will be able to deliver the rocket car in three days at the latest. ”

Qingyang Zi is full of confidence, now the magician's camp is bigger than the military camp, and the people sent by the magic association are full of enthusiasm and are immersed in the construction of rail cars.

The Xijiang Tunnel implements a double-track operation, and trains on the north and south banks can depart at the same time, and four sets of rail cars are required to run at full capacity, which is not a problem for hundreds of magicians.

Walking at the forefront of the escort army were twenty iron pulleys, this kind of heavy siege equipment was originally difficult to march, but it was much easier to tow it with rails.

A pulley plate is placed under the car, and a war horse can pull one, and the driving sergeant only needs one.

Behind the iron pulley were the ballistas, forty ballistae to the covet of all legions, and in terms of combat power on paper, the Protector Army was the best in defending the city.

"The Protector Army has both offense and defense, and has become the main force of our army, which corps does the general think they can replace?" Wang Deng rushed over because of Wu Yi's matter, and stopped by to see the situation in the Xijiang Tunnel.

"Except for the rebellion, the armor will be collected, and the day the counterinsurgency theater is revoked, there will be no protectors in the world. Ding Kui nodded at the acquaintances in the team from time to time.

"It's a pity!" Wang Deng looked sorry, "Such a strong army does not belong to the Commander's Mansion, this is a loss for the kingdom." ”

"If there is no war in the kingdom from now on, I am willing to suffer even greater losses. ”

At this time, who dares to say that Ding Kui is a militant will definitely be sprayed to death by spitting stars.

The incredible look in Wang Deng's eyes flashed, "There are several legions that need to be rebuilt, everyone in the Protector Army can become the backbone, the Commander's Mansion has an establishment, and you will return to the General Staff in the future." He still didn't give up.

Ding Kui turned his head to look at Wang Deng and said seriously: "Half of them are retired officers and soldiers who are not suitable for returning to the army; the other half are fleeing civilians who need them to go back to rebuild their homes; and the rest are willing to join the army, I will not stop them, and the army will have to find another way to rebuild the commander's mansion." ”

"Well, it's all your business anyway. Wang Deng's eyes rolled, "I see that rocket car has a strong impact, can you transform it for combat?"

"No, I can't. Ding Kui immediately rejected, "The rocket car has many limitations, it needs rails, it needs to go in a straight line, the ground fluctuations cannot be too large, and the size and weight are not conducive to hiding, which is difficult to overcome on the battlefield." ”

"In this way, traitors can't imitate it?" Wang Deng didn't care about logistics, and he didn't worry about the rebels copying rocket vehicles for logistics, but he was afraid of appearing on the battlefield.

"The traitor's fire power is strong, but the rocket car still needs the power of the ground system, don't worry, they can't build it. ”

Ding Kui thought that the rail car might be imitated, but in Shaodian he was not worried, it was difficult to build the railroad track without the help of a local magician, so don't think about imitating the rail car.

"How much does the Xijiang Tunnel cost?" he didn't want to set the price.

The additional cost of the army needs to be approved by the logistics department, and there is no cost involved in marching in the country, but the cross-river tunnel and rocket car are new things, and if you don't rely on magicians, then the cost of building them is astronomical, just like the portal of the magic guild, and the king has to pay the cost to use it.

"This is a matter for the logistics department, so I won't be involved. ”

Wang Deng looked at Ding Kui's expression, and had no choice but to say again: "Well, the Commander's Mansion does not compete with the people for profit, and you can refer to the example of the people." ”
