Ask Sword

Good Sunrise!

Li Ang took off his armor and walked towards the crowd. Yang Yu, Li Wei and the others applauded him, but more people were dumbfounded.

As for the freshmen who were close to Pei Jing, many of them had unconvinced expressions on their faces.

There's no one who throws ashes in people's eyes during battle.

Yeah, it's a bit... non-martial arts. Is that okay?

Pei Silang is too wronged to lose

Tread Tread.

Pei Jing stepped out of the battlefield with somewhat heavy steps.

He waved his hands at the approaching friends, indicating that he was fine, then with a sullen face, he nodded solemnly at Li Ang, This time, I lost.

The friends on the side were unconvinced and wanted to interrupt, but Pei Jing stopped her with her eyes, If you lose, you lose. There is no excuse. Li Ang uses all the equipment in the martial arts arena, and I am convinced.

That's right.

A doctor of Xuegong who was filling out the results on the list raised his head and said to the students: Do you think fighting is a noble and elegant thing?

Combat is to knock down and destroy the opponent as the ultimate goal.

Words like 'barbaric', 'despicable', 'vulgar', and 'indecent' are only qualified to be used by those who survived.

The dead are not qualified to condemn each other.

Exactly.

Another doctor of Xuegong taught: You will understand when you travel in the third and fourth year of school.

There are countless dangerous aliens and monsters in the world, and they don't know any martial arts.

Even monks in the Zhuxiao realm will die if they are plotted against, their hearts are stabbed, and their heads are chopped off.

Not to mention you guys.

Bad people are cunning and cunning, and good people can only survive if they are more cunning and cunning than them.

In the past, there was a school inspector who was too naive to help the refugees, and was almost beaten by the villains, put on a sack and sank into the river.

The two Xuegong doctors look at you, and I say a word,

Expressed appreciation for Li Ang's behavior of giving full play to his subjective initiative, tying talismans to flying arrows, and using sand and dust-sweeping talismans to confuse his opponent's eyes,

And instruct other freshmen.

The status of a school disciple is only valid in the civilized world.

And in the poor mountains and rivers that are not under the control and jurisdiction of the Yu State court, or when facing those villains who are willing to take risks,

Being a disciple of the academy would not have any effect, and one could only rely on one's own vigilance.

According to Li Ang's memory in the other world, except for the monks who practice the body, they are all high in attack and low in defense, and their physical fitness is still within the scope of human concepts.

To participate in the chaotic battlefield environment, one must use protective talismans, release protective spells, or use mental power to defend the body surface in advance.

Ordinary monks were attacked by assassins without preparing protective facilities in advance, and it was easy to die for no reason.

Rumor has it that in Xijing, there is an army of assassins composed of mortals.

Their spiritual talent is extremely poor, and they don't have any spiritual energy fluctuations on their bodies, so they won't be detected by the spiritual energy. And he has taken special pills since he was a child, which can hide the breath of living people and enhance his basic physical fitness.

This group of people will go through the rigorous training of the Xijing Palace and learn the skills of camouflage, lurking, concealment, assassination and assassination.

Equipped with some special alienated items, they can even coordinately assassinate monks at or above the Cloud Patrol Realm.

It has always been a handy tool used by the Xijing royal family to suppress domestic rebellions and cut off disobedient monks.

The two academic doctors cited many examples to teach the freshmen

Fifty credits will be added to the students who won the actual battle and those who performed well.

Li Ang, He Fanshuang and others added an additional 80 credits and encouraged others to study.

After the actual combat class, the students dispersed, and Li Ang went to the forging workshop, preparing to forge a handy weapon for himself.

Mosi can't show it in front of thousands of people. Normally, she also needs to have reasonable self-defense methods.

The forging workshop was still in full swing, and some senior students were attending classes. Li Ang went around that area, came to the back of the workshop, and found Tantai Leshan, who was usually in charge of the management of the forging workshop.

Oh, Risheng, you are here.

Tantai Leshan is discussing something with Su Feng and several other doctors at the moment.

Meet Tantai Siye and Dr. Su

Li Ang greeted respectfully, his attention was suddenly attracted by the things on the table, Huh? This is

An improved version of your model airplane.

Tantai Leshan picked up a fairly complicated metal object from the table, which consisted of gears, connecting rods, pistons, crankshafts, belts, etc.

We have been trying to increase the flying speed of the model airplane during this time. The strength of the material used to make the model airplane and the strength of the power provided by the talisman are no problem.

The problem was with the propeller.

Tantai Leshan explained: The method we used at the beginning was to stick talismans such as breeze talismans directly on the propellers to provide wind power.

But the talisman itself will affect the performance of the propeller, and if the propeller turns too fast, it will damage the talisman.

So we tried to improve, built the talisman into the propeller,

Or use the method of Candle Heaven Realm level to make the propeller itself into a talisman.

But there is still the same problem—use the wind to drive the propeller, make the propeller rotate, and then drive the model aircraft, there will be waste in the middle, and the efficiency is too low.

So we thought of another way,

Ph.D. Su Feng said: Maybe no longer using talismans to directly generate wind to drive the propellers, but using devices to use the energy provided by talismans to rotate the metal rods connected to the propellers.

Make the metal rod drive the propeller to rotate to generate wind force.

Such energy loss is smaller and the efficiency is higher. The flight time provided by the same talisman is also longer.

this

Li Ang was stunned, and checked the metal mechanism.

What Tantai Leshan, Su Feng and others fiddled with really looked like a primitive reciprocating piston engine.

The reciprocating piston engine in the memory of the foreign world can use the heat energy generated by the burning of dyes to push the piston through the expansion of liquid or gas, and convert the pressure into rotational kinetic energy.

With the engine, it means the liberation of manpower, and the transportation of goods no longer needs to rely on animal power.

Locomotives, railways, lathes, ships, airplanes, factories.

Images from countless memory fragments flashed across Li Ang's mind, and his heart beat violently.

No, Dr. Tantai, Dr. Su, you two are a little too fierce, so you got the engine out?

The significance and influence of the birth of the engine in the memory of the alien world are fully described,

Li Ang calmed down, observed again, and his mood gradually recovered.

This engine does have a reciprocating piston structure, but it is not fully enclosed.

Instead, there are two holes in the cylinder at the bottom of the engine,

The air inlet and outlet holes, respectively,

The strong wind attracted by the wind talisman can be used to pour into the engine, push the piston back and forth, and convert the pressure into rotational kinetic energy.

Although such an invention is equally ground-breaking, it has its shortcomings.

Our headache now is that the efficiency of this structure imitating the puppet technique of the former Sui Dynasty is only a little higher than the original direct sticking of talismans.

Doctor of Science Su Feng scratched his head and said: The strong wind attracted by the wind talisman will push the piston. But most of the wind power is inside the air chamber and is consumed internally. Moreover, the wind talisman cannot be controlled to automatically shut down to save the power of the talisman.

Maybe.

Li Ang hesitated and said, Is there any other way?
