After the three heads of the family discussed, since they could not be enemies, then we would make friends with Li Rujin according to what Marshal Yuwen said, and let Li Rujin think of a way out for our scholars, and I hope that Li Rujin can help the scholars to make suggestions and change the current decline of the scholars. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoAfter setting the general direction, let's see if you make friends with Li Rujin.

After some discussion, the heads of the family decided to act in two lines, first, to reply to Marshal Yuwen and agree with his suggestion, and at the same time to send more important figures in the family, such as the young masters of each family, who are of similar age and are more likely to have common topics. From the frontal contact with Li Rujin,

Second, send direct disciples in the family with flexible minds and lively personalities to approach Li Rujin from the side, and strive to do what he likes, win over Li Rujin, and leave a good impression on Li Rujin no matter how bad it is.

Third, use the family's elite forces to investigate Li Rujin from all aspects, observe Li Rujin from all angles, and understand Li Rujin, but there is a premise, it must not be detected by Li Rujin, and the province's stealing of chickens and rice will not make a bad impression, and at the same time provide intelligence support for the first two co-opted personnel.

After the decision was made, the heads of the three families began to discuss the issue of manpower, they couldn't send all three young masters to go at the same time, that action was too obvious, taking advantage of Marshal Yuwen's east wind, Yuwen Haoyuan, the young master of the Yuwen family, was the best candidate for the first wave of direct contact with Li Rujin.

The other two also selected shrewd and capable candidates from the direct disciples in the family to contact Li Rujin from the side. The investigators were led by an old and sophisticated housekeeper-level person, and they were divided into two directions, one was responsible for going to Haizhou to investigate, and the other was going to the imperial capital to secretly observe Li Rujin.

The letter has been sent, the messenger is on his way to the Marshal's Mansion in Xining, the investigators have also been drawn and are moving towards the imperial capital, and the side contact personnel have also set off with them, striving to create an opportunity to contact Li Rujin as soon as possible.

And Yuwen Haoyuan waited at home, waiting for Yuwen Marshal's reply.

After receiving the letter, after reading it, Yuwen Dashuai finally put his mind at ease, he was worried all the time, worried that the Yuwen clan would not be able to let go of his pride, and if he had to compete with Li Rujin, then he would become a sandwich biscuit, which was very uncomfortable.

Since the Shi clan accepted his suggestion, he didn't mind being a good person once, pulling a line for both sides, and immediately replied to the letter, making an appointment to meet at his home in the imperial capital. And he also took a leave of absence and rushed back to the imperial capital, he owed a lot of favors to Dashuai and Li Rujin, so he took this opportunity to go back and deal with it.

At this time, Li Rujin was busy with work, and he basically didn't care about the reform now, and put his mind in the laboratory of the military department, the prototype of the helicopter had been successfully tested, but the model was too small, and the load capacity was only a pitiful 120 kilograms, but other data still made Li Rujin very pleased, whether it was speed, altitude flight radius, or mechanical properties, the use effect of the motor, or the storage capacity of the battery, all met or exceeded Li Rujin's expectations, especially the storage capacity of the battery, which greatly exceeded Li Rujin's estimateThis is also the first time that Li Rujin has truly seen the world's top power technology.

Two batteries weighing 120 kg each, for the 780 kg prototype, providing nearly 1000 kilometers of endurance, this data greatly exceeded Li Rujin's estimate, but also gave Li Rujin a big surprise, but the price of the top electric board also gave Li Rujin a "surprise" The cost price of a electric board reached 5500 yuan, this price, high!

The development of high-horsepower diesel engines has also entered a new stage, and under the guidance of Li Rujin, the development of V-shaped engines has begun. V-type engine refers to the cylinders of the engine arranged in a V-shape, which reduces the space occupied by the engine, and at the same time increases the number of cylinders of the engine and increases the power of the engine. Li Rujin's research and development target is the V-2 tank series engine of the former Soviet Union.

V-2 tank engine is a whole series of engines specially developed by the Soviet Union for tanks, its basic model is V2-34 engine, the engine is V-type 12 cylinders, a total of 22 models were derived in the future research and development, Li Rujin can not develop all the models, can only choose a few of them, naturally aspirated such as V2-34, V-54, V-55, etc., and the supercharged engine is not in Li Rujin's consideration for the time being.

The research and development of the engine has now entered a bottleneck stage, that is, the casting material of the engine is unqualified, and the miniaturization of the engine cannot be realized, which makes Li Rujin a headache, and materials science is a very large discipline.

The current investment in science and technology cannot support the terrifying investment in materials science research, so Li Rujin has to look for suitable materials in his memory again. Thinking about it, Li Rujin still took out the dense graphite cast iron method of diesel engine, which will greatly reduce the volume of the engine, although the process is somewhat cumbersome, but the diesel engine manufactured will have a qualitative improvement.

After coming up with an improvement plan, it would be some time before the new cast-iron engine was manufactured, and Li Rujin once again focused on the helicopter. There is no need to worry about the materials used to make helicopters, this piece, the materials science of the Dawen Empire has a certain technical accumulation, although it is lacking in some aspects, but there are many alternative materials that can be supplemented.

Thinking of materials science, Li Rujin couldn't help scratching his head, this thing is too difficult to get, it is completely dependent on strong capital investment, thousands of consecutive tests, tens of thousands of times will have a certain chance to develop a new material, and now the research and development of materials science is a completely impossible thing. It still requires experience and recipes from previous lives.

Thinking of this, Li Rujin returned to the office and wrote out the recipes of some of the materials he needed now, and accumulated raw materials while keeping them secret. Armor steel for tanks, high-precision steel for engine nozzles, hull steel, deck steel for ships, and a series of different steels.

After writing it, Li Rujin went directly to Dashuai's office and handed over the recipes to Dashuai. Put it in Li Rujin's own hands, Li Rujin is not at ease with himself, put it in the laboratory, Li Rujin will not be at ease in the laboratory, this is still in the safe in the marshal's office, where is the safest place in the empire.

The safe in the marshal's office is not in the marshal's office, this is just a statement, where the specific place, there may only be three people in the empire who know, one is the marshal himself, and the other two may be the emperor and Marshal Yuwen.

Da Shuai took the formula handed over by Li Rujin, after Li Rujin's introduction, those few pieces of paper, in Da Shuai's hands, are also like a thousand catties, the value of these formulas, Da Shuai himself can not estimate, these formulas are not a quantitative improvement to the military equipment of the Dawen Empire, but a qualitative improvement. These formulas cannot be measured in monetary terms.
