The shooting range is a large open space, and there are many small hills on this side of the target area, planted with trees, and a lot of wild grasses and bushes, and the highest hill is bare, all of which are used by artillery.

The location of the target was on the flat ground at the foot of the mountain, and it had been isolated at this time, and only Li Lu and Pei Lei could see the damage up close.

Li Lu and Pei Lei walked to the target, Pei Lei pointed to the part that was directly hit, controlled his excitement, and said in a low voice, "This standard armor steel plate, I dare to say that even if it is not ahead of the world level, it is among the world's advanced levels!" ”

Shaking his head, Li Lu said, "It's not to that extent, the Americans have depleted uranium armor, they have depleted uranium armor-piercing shells, and the power of their 105mm tank guns surpasses Maozi's 115mm guns, Maozi was forced to come up with 125mm smoothbore guns, and NATO countries immediately came up with 120mm smoothbore guns, and the power, accuracy and service life are all above Maozi's 125mm smoothbore guns." ”

"However, this is a very big breakthrough for our armor development work." Li Lu added.

Pei Lei said with a smile, "You see it too shallowly." ”

"Firepower, protection, and mobility are the three most important indicators of a tank," he said, pointing to the armor that was still strong after being hit hard. But there's a paradox here. Increased protection necessitates weight gain, and weight gain affects mobility. Countries continue to develop higher horsepower engines because the weight of tanks continues to increase. When researchers find it increasingly difficult to develop more horsepower, they wonder if it is possible to make a tank more protective at the same weight. ”

He knocked on the half-crippled armor steel plate and said, "The armor is lightweight." Therefore, the success of our lightweight armor steel plate affects the comprehensive performance index of the tank. Not to mention anything else, it is the 59 Tan in service, replaced with a new type of armored steel plate of the same specification, the protection force will be increased a lot and the mobility will not be affected, if the same protection force is used as the standard, the weight of the vehicle will be greatly reduced, and the mobility will be improved! ”

"In a word, with lightweight armor steel, we can calmly plan and distribute other main performance indicators of the tank!"

Li Lu suddenly realized and said, "So, if we get a high-power engine and a high-performance tank gun, there will be no other technical problems in our development of a new tank?" ”

"It's not that simple." Pei Lei shook his head and said, "The development of the main battle tank is a huge project involving dozens of disciplines, engines, artillery, these are just some of them. However, with a good engine and artillery, it will definitely save a lot of time. ”

Speaking of this, Pei Lei waved his hand and said, "Don't talk about this, the lightweight armor steel is successful, I will start to make 59 changes in dress, and when the American team is in place, the engine and artillery will be negotiated, and the prototype car will be tested immediately." ”

Li Lu thought for a while and said, "Pei Gong, you can make some improvements first, try to produce one with new armor steel, and use the original engine and artillery." The performance is passable, and it can be sold cheaper. ”

Pei Lei patted his head, "Yes, why do you have to wait for a new engine and a new artillery?" ”

"Pei Gong." Li Lu dragged Pei Lei, who was about to go mad again, and instructed, "The news of the success of the new armored steel must be blocked, and the confidentiality work must be done well, especially the formula, that thing is a priceless treasure." ”

"I understand, don't worry." Pei Lei said.

Maybe it's because the tanks that Li Lu has been in contact with all his life are third-generation main battle tanks that are so advanced that they are a mess, so he doesn't have much feeling in the face of such a technological breakthrough. He was only the first to realize that this news should be kept strictly confidential.

Pei Lei is different, so many steelmaking plants and so many researchers have not come up with a new type of armor steel that has been working on for more than ten years, and an unprofessional research team set up by Pei Lei has done it, and it is produced by a small steelmaking plant under the Guangming Factory.

Leaving aside other aspects, this glory alone is something that many people cannot afford.

Pei Lei is almost an all-rounder, and he also has two ideas in steel development, he knows that if better raw materials are used and further improvements are made in the process, the indicators of the new armor steel will be better!

It is not hard enough to be used to make tank armor steel plates, judging from the test, the steel plate refined by the formula provided by Li Lu has good toughness, which can be seen from the fact that the steel plate is not broken. The performance of this indicator is impressive.

On the way back, Li Lu is also pondering whether lightweight armor steel can be used in automobile manufacturing, girders, drive shafts, suspensions, and frames, there should be no technical problems. If it works, maybe the first car built by the Red Star Tractor Factory will be crowned as "the world's first production car using lightweight special steel".

With a concrete idea, he immediately thought of the construction of the Red Star Tractor Factory, which had so far been a wasteland.

Li Lu didn't have a penny in his hand.

The expansion of Fenyuan Company occupies most of the funds, and it is difficult to return the funds without a month. In addition to the 100,000 yuan on the books of the Red Star Factory, all he can use now is the three big yellow croakers left by his grandfather - convincing Jack to use one.

The remaining two were still with Tang Jiu, but Li Lu didn't plan to use them anymore, and those two big yellow croakers had to be kept as hard currency for war readiness, leaving a way back for himself. He was engaged in intelligence work in his previous life, and he was used to leaving a way back.

The T-62M, which had completed major maintenance, was galloping on the runway of the large playground in the test area, rolling up bursts of dust, Sun Jiangtao brought a group of workers and technical personnel to wait for the test results at the starting point, and three or five officers from the tank regiment who came to accept stood together, pointing at the T-62M running on the runway from time to time. If everything is normal, it will be delivered to the tank regiment, and after such a long delay, the tank regiment will not be able to wait for a long time.

Li Lu walked over to see the excitement, looking at the officers as he walked, and when he saw one of the officers without his left arm, Li Lu suddenly stopped and shouted in surprise: "Company commander!?" ”

The one-armed officer stopped talking and looked over, full of surprise, "Li Lu!" ”

"Company commander!" Li Lu ran over and saluted excitedly.

The one-armed officer returned the salute, and with one right hand slammed Li Lu into his arms and patted him on the back vigorously, "You kid! Let me see! ”

As he spoke, he pushed Li Lu away and took a half-step look at Li Lu from beginning to end, and nodded with satisfaction, "Okay!" Good! All beards and all tails! Good spirits! ”

Li Lu was very excited, "Company commander......"

The one-armed officer turned to several other tank regiment officers and said, "He is the warrior I often mentioned to you about killing three in and three out on the Annam front!" He saved my life! ”

The one-armed officer's name was Zhang Pingshan, chief of staff of the tank regiment.

The officers of the tank regiment stood in awe and saluted Li Lu.

Li Lu's deeds of entering and exiting three times on the Annan front are almost a legend to many officers and soldiers who did not participate in the war.

The real situation is that Li Lu's infantry regiment retreated to the defense area after completing a large-scale combat operation, and in order to find out the artillery position of the Vietnamese army, Li Lu's company formed an assault team to sneak into the enemy's abdomen for reconnaissance, and when retreating, it was intercepted, and the company commander, who personally served as the leader of the commando team, led two soldiers to cover the retreat of the rest of the personnel.

After waiting for more than three hours at the established rendezvous point and not waiting for Zhang Pingshan and the three, Li Lu ignored the dissuasion and went into the enemy's belly alone to rescue Zhang Pingshan and the three. When Li Lu found Zhang Pingshan, he was already wounded, his left arm was blown off by a shell, and two other soldiers were killed.

At this time, the main forces of the Vietnamese army blocked the border, and Li Lu and Zhang Pingshan fell into a heavy siege. Li Lu actually took Zhang Pingshan to once again assault the Vietnamese army in depth, sneaking 30 kilometers in one day and one night, greatly mobilizing the main force of the Vietnamese army and creating an excellent opportunity for our army to destroy the enemy in the simultaneous pull-out operation.

When they penetrated deep into the enemy's depth for the second time, Li Lu and Zhang Pingshan also easily cut off a command post of the Vietnamese army.

Immediately, tens of thousands of Vietnamese troops launched a frantic pursuit of Li Lu and Zhang Pingshan, and the two people who made a great detour to the border were pursued extremely fiercely, as if the entire Vietnamese army deployed in the border area was targeting them.

When Zhang Pingshan thought that he was cornered, Li Lu once again made an astonishing move, and actually took Zhang Pingshan to turn around for the third time and enter the depth of the Vietnamese army - because there are loopholes in only this one direction. At that time, Zhang Pingshan was almost unconscious, and he almost relied on Li Lu's back to walk.

Just when Zhang Pingshan thought that he wanted to sacrifice his life for the country, Li Lu completed a great feat.

He actually carried Zhang Pingshan on his back for three days and three nights in the tropical rainforest, turning from the battlefield on the Western Front to the battlefield on the Eastern Front!!

Li Lusheng carried Zhang Pingshan, who was in a very dangerous situation at that time, out of the tropical rainforest, and traveled more than 120 kilometers in three days and three nights!

The Vietnamese troops who surrounded and intercepted did not believe that this was true at all!

Even the Yunnan front-line command post, after receiving the news from the Kunming front-line command post, thought it was a prank!

After this battle, Zhang Pingshan, a first-class meritorious soldier who returned from injury, was transferred back to the rear unit as a battalion commander, and only one year later, he was transferred to the chief of staff of the tank regiment stationed in Lunan, and his future was bright. Li Lu, who was also a first-class meritorious hero and won an individual honorary title, was punished at the same time for disobedience on the battlefield, and after staying on the front line for two years, he made an exception and returned to the local area by changing jobs.

In Zhang Pingshan's heart, Li Lu is not only an old subordinate, but also a benefactor. Maybe Li Lu just disobeyed the order and went back to rescue him out of disobedience because he didn't abandon any of his comrades, but here in Zhang Pingshan, Li Lu undoubtedly sacrificed his future to achieve him.

In terms of merit, Li Lu's is bigger than anyone else's, but he disobeyed. If the merits and demerits do not offset each other, what kind of credit should be what kind of merit is what kind of merit, and what kind of punishment should be punished.

As a result, Li Lu didn't even have a chance to do it, and Zhang Pingshan was on the rise.
