Check the points and treasure chests.

Li Polu immediately understood what was going on.

Look up at the sky, the sun is smiling.

Looking down at the ground, there is no grass.

The sun is shining brightly now, it’s a great time to draw the lottery!

"Zero, start level 3 ten consecutive draws."

[Ding, the lottery is completed. Congratulations to the host for winning:

Nanyou No. 2 Cultivation Notes (Epic Level).............Andromeda Royal Special Food (Perfect Level).........2.4L Naturally Aspirated V8 Engine Design Idea (Epic Level). 】

After checking what he got from the first 10 consecutive draws, Li Polu was stunned. Royal special food? What the hell?

Li Polu puzzledly opened a colorful small box, and then after opening it, three half-moon-shaped foods were neatly placed inside. The whole thing was golden yellow, slightly oily, and looked shiny.

There is a circle of fine folds on the edge of the food, which looks like a beautiful lace on it.

Li Polu looked at the three little things in the box and felt that they looked very familiar, as if he had seen them somewhere.

After all, it was something given by the system, so Li Polu didn't think much about it. He just picked one up and put it in his mouth.

But as soon as he took his first bite, Li Polu suddenly remembered something.

This familiar look, familiar taste.

Isn’t it just a leek box?

But to be honest, it tastes really good.

In no time, he had eaten three leek boxes.

As for the box, he twisted it lightly and it broke into pieces on the ground.

Li Polu looked at the inferior packaging and couldn't help but complain again.

That's it? And it's a special gift from the royal family. The royal family really doesn't live a good life.

Apart from the little episode with the leek box, the rest was really thanks to the blessing of the martyrs, and I was able to make a payment on the first try.

Nanyou No. 2, needless to say, is a three-line indica hybrid rice.

It is also the first superior hybrid rice combination successfully cultivated in my country.

It has the characteristics of high yield and strong adaptability.

Under the same conditions, Nanyou can increase yield by 50-100 kg per mu, which is about 20% higher than that of local high-quality varieties.

Of course, as the first generation, Nanyou also has some shortcomings of its own, such as not being resistant to rice blast, average rice quality, and poor taste.

But what did it matter, didn't he just happen to know a professional in this area?

Moreover, this thing was invented by the other party. It is reasonable to hand it over to him and let him make it more than ten years in advance!

The moment he saw Nanyou No. 2, Li Bolu had already figured out how to deal with it.

As for another highlight in this ten-draw streak: a 2.4-liter naturally aspirated V8 engine.

This thing is amazing.

The invention and use of the 2.4-liter naturally aspirated V8 engine can be pushed back to the late 80s.

It was first installed on the Renesas LS400 flagship sedan.

It has the advantages of strong power, smooth operation and charming sound.

But at the same time, as the main engine of high-end models in the future, it also has all the shortcomings of high-end things.

For example, the fuel consumption is terrible, the cost cannot be compressed, and the size and weight are large.

But overall, this engine, which was used by F21 in the early 1st century, would definitely be a knockout in this era.

Fortunately, it is naturally aspirated. So Li Bolu still has a chance to make it. If it is turbocharged, he will be in big trouble.

Being able to see but not being able to use, is there anything more painful in the world than this?

However, these are not the issues that Li Bolu is considering for the time being.

Now, while we are under the protection of the heroic spirits, we must first draw the lottery and have fun!

In the second round of draws, apart from the inferior rewards below the perfect level, three pretty good things were drawn this time.

The epic F-15 Eagle. This thing isn't that far out of the box. Uncle Sam will probably be flying it for the first time in about 10 years.

It seems that the plan was only launched last year, and the bidding began three years later (3).

The F1q has an excellent aerodynamic layout, low wing load, and a high thrust-to-weight ratio. Its weapons and flight control systems use advanced automation designs.

安装有一门20毫米M61A1机炮，共有11个武器挂架。其中机翼6个，机身5个。其总挂力可达7300千克。

It is also worth mentioning that after some modifications, this thing can be transformed into a bomber - F15E 'Strike Eagle'.

But this one's first flight will be even later.

The epic T90 main battle tank. This thing is quite practical.

This is a main battle tank developed by Beixiong in the 90s.

It uses a 125mm smoothbore gun and is equipped with an automatic loader.

It can fire a variety of shells, including armor-piercing shells, anti-tank shells and fragmentation grenades, and in order to make up for the gap between the fire control system and that of Western countries, it can also fire AT11 anti-tank missiles.

The armor penetration of AT11 at a distance of 5000 meters can reach 850 mm. It can also attack low-altitude targets. This is a bit abnormal.

Auxiliary weapons are a 1mm coaxial machine gun and a 7.62mm anti-aircraft machine gun.

There are three types of armor: load-bearing armor, explosive reactive armor, and traditional steel armor.

Explosive reactive armor is installed on the turret, including the roof, to protect against Hell-Attack missiles.

Nickname: Red-eyed monster.

It's really good after using it.

Moreover, Li Bolu couldn't help but think with a sense of evilness, what would be the reaction of the Northern Bear's armored vehicles on Zhendao in a few years when they saw this tank that was clearly of their style.

As for the last one, it is a half-immortal fragment: the DUV lithography machine.

It is true that this thing is far ahead, but there is really nothing we can do about it now.

The development of lithography machines can generally be summarized into six stages.

The origin of photolithography can be traced back to the 50s. During this period, photolithography technology began to be applied to chip manufacturing. The main technology used was optical projection technology.

In the next stage, that is, in the 70s, photolithography machines began to become popular, and the technology shifted from optical projection to contact photolithography. However, the resolution and accuracy still could not be improved.

Later, the progress of semiconductor technology and optical technology promoted the development of lithography machines. Projection lithography technology emerged, and the accuracy and quality were improved.

The next stage of projection technology uses laser technology.

Now Li Polu has obtained half of the DUV technology, which is the next stage of laser technology, also known as deep ultraviolet lithography technology.

The next stage is the EUV extreme ultraviolet lithography technology used by Li Polu before he traveled through time.

Optical projection technology - contact lithography technology - projection lithography technology - laser technology - deep ultraviolet lithography technology - extreme ultraviolet lithography technology.

At present, China has not even come into contact with the second-stage contact lithography technology, and has directly started with the fifth-stage deep ultraviolet lithography technology.

Li Bolu knew without even thinking that this was bound to be a drama.

There are two key points here: immersion lithography technology and multiple exposure technology. He couldn't solve either of them.

After all, he is just a wall hanging, not a scientific madman. He can't do it, he can't do it at all.
