Chapter 246 Three Years
During the construction research, Liu Xiu felt that time passed very quickly. In the blink of an eye, he went from 1956 to 1959, and three years passed in such a rush.

In the past three years, Liu Xiu's titanium alloy production and processing plant was naturally set up, and Liu Xiu's Challenger helicopter was naturally built as expected.

However, because the production and processing of titanium alloys are troublesome, the cost of the Challenger combat helicopter cannot be reduced.

Therefore, considering the possibility of transportation, Liu Xiunong's Challenger helicopters were divided into two types. The first type was the Challenger combat helicopter used to lead low-altitude raids.

The entire fuselage is made of titanium alloy, and grille armor is added to the fuselage and bottom to protect against individual rockets and recoilless cannon shaped armor-piercing projectiles.

Moreover, Liu Xiu personally tested it. Even Liu Xiu couldn't knock it down with RPG rockets. Even if he hit the tail propeller, it was useless, because the tail of the coaxial twin-rotor helicopter was no longer a vital part. .

Its maximum speed is 480 kilometers per hour, it has six tons in the air, and its maximum load is ten tons.

The other type is the Challenger transport helicopter. Since it does not require protection, it is made of relatively light aluminum alloy. Of course, in order to ensure strength, the fuselage frame is still made of titanium alloy. Its empty weight is only Three tons. Of course, because the engines used are the same, the maximum take-off weight is also ten tons.

Of course, the reason why Liu Xiu wanted to get a transport helicopter was to use it for his special operations team. Four hundred and eighty kilometers per hour is much easier to use than an aerial three-hop helicopter that is more than 100 kilometers per hour.

And because titanium alloys could be mass-produced, Liu Xiu replaced the special forces' original steel bulletproof inserts with titanium alloy ones.

But before Liu Xiu could speak, Wu Qianli, Wu Wanli’s brother, spoke:

That's right, although Liu Xiu was empty-handed, the special forces team has always been under Liu Xiu's direct leadership, and the members who entered the special forces team all called Liu Xiu captain according to Liu Xiu's requirements.

"Captain, I want to be with my brother, so assign me to the assault group! And my level has reached the level of dark strength, and I am qualified to enter the assault group!"

The team members responsible for fire cover and sniper operations only have bulletproof helmets and bulletproof inserts made of titanium alloy.

After all, the firepower team and the sniper team have to carry a lot of ammunition, and they are not at the front to attract firepower, so wearing such full-body armor is naturally unnecessary.

This kind of weight can only be used normally by martial arts masters in the special operations team, so Liu Xiu naturally only allocated this kind of full-body armor to the stormtroopers in the special operations group.

This kind of armor is almost the same as a steel suit and can withstand heavy machine gun bullets. However, even if it uses titanium alloy, its weight still reaches one hundred and twenty kilograms in order to be lower than the heavy machine gun bullets.

"Wan Li, don't mess around and obey the captain's instructions!"

And Liu Xiu also used titanium alloy to specially create a full-body armor similar to Iron Man Zhanyi.

However, just when Liu Xiu was distributing titanium alloy full-body armor to the special forces members in groups, Wu Wanli said:

This is a unique honor given by Liu Xiu to the special forces. Others still call Liu Xiu Kongji, or Liu Kongji.

However, Wu Wanli said to Liu Xiu firmly:

"Captain, my realm has reached the dark realm. According to your requirements, I am qualified to join the stormtroopers. This is your rule!" After Liu Xiu heard Wu Wanli's words, he naturally couldn't break his own rules, so he He opened his mouth and said:

"Since you insist on joining the stormtroopers, then put it in Wu Qianli's group!"

That's right, there is not just one group of stormtroopers but several groups. Because Wu Qianli is willing to work hard and he was also the commander of the intervening company before, his commanding ability is not bad, so Liu Xiu let Wu Qianli be the stormtrooper. One of the group leaders.

Because of the economic development in the past ten years, the number of Liu Xiu's air force has also increased. Now, the number of people belonging to Liu Xiu's air force has also changed from 10,000 after the Battle of Xian'ao to today's There are more than 100,000 people.

As the number of people increased, the number of people with martial arts talents naturally increased. However, Liu Xiu chose a cautious method of selecting the best to increase the number of special forces from the original one hundred or so. It has become a battalion of more than 300 people today.

After Wu Wanli heard that Liu Xiu agreed to his request, he was naturally happy and said:

"Thank you Captain!"

In response, Liu Xiu waved his hand and said:

"When you join the stormtroopers, you must obey the orders of your team leader. If I find you disobeying orders, then don't blame me for kicking you out of the special forces!"

Regarding Liu Xiu's words, Wu Wanli naturally quickly promised to obey Wu Qianli's orders.

In fact, Wu Wanli wanted to join the Stormtroopers. In addition to wanting to protect his brother, more importantly, he felt that the full-body armor was particularly cool and beautiful.

But this is not surprising, after all, this Iron Man suit will be one of the most popular science fiction movies in decades!
So there is nothing to say about its appearance, but it is a pity that today's electronic technology is not yet developed, so Liu Xiu wants to make a mechanical exoskeleton like a real steel suit, but it is difficult for an ingenious woman to make a meal without rice.

Therefore, he could only get a manpower-driven one. However, although it was a superficial one, Liu Xiu still installed a personal infantry phone that could be used for communication and command. After all, this thing was relatively simple.

Of course, relatively significant things have happened in the past three years. For example, Su Tuo and Mi Tuo both launched Zhouji Express, but fortunately, they also launched one this year.

Although it was many years in advance, it still cannot change the big welding that started this year. Fortunately, Liu Xiu had already suggested building a granary before. Coupled with the popularity of walking tractors in recent years, the per capita cultivated area has greatly increased. Increase, so the supply of grain in recent years has basically exceeded demand.

Because of this, it took only a few years for the grain in the granary to reach a point where Quan Gao could eat it for two years.

In addition, dry welding is only a perylene recipe, so two years of food is enough.

However, Liu Xiu felt that since it was dry welding, it would be impossible to grow the villagers anyway, and it would be idle if they were idle. It was better to mobilize them and carry out water diversion projects, so that they would not have to worry about droughts and lack of water in the future.

Liu Xiu's proposal naturally surprised the superiors, but then his eyes lit up and he made a demonstration. The result was naturally feasible. After all, this method was not thought up by Liu Xiu himself, but by forty I got it after many years of practice!
So a vigorous canal repair project began, and Liu Xiunong's walking tractor was put to use again at this time.

Because after the walking tractor is loaded with the body, it can transport the bricks, stones and cement needed to repair the canal, and this is much more efficient than using human hands to pull it by oxcart. Of course, in order to cope with such a large project, other Cement plants are naturally put into operation one after another!
