When the bluestone strip was found, everyone was still dodging the boulder attack that flew from nowhere.

Zhao Rui didn't delay much, and immediately drew a strong talisman and a golden body talisman, and then raised the barrel of the cannon and asked the soldiers to use bluestone strips to raise it.

Some veterans are okay to say, but some recruits have never seen Zhao Rui's great strength, they are all stunned, and one recruit was hit on his toes by a boulder because of distraction.

"Be careful! It's still fighting! Zhao Rui frowned and shouted, and at the same time, the movements in his hands did not stop, and he continuously completed all the elevation of the gun barrel.

Zhao Rui's idea was this, since the rocks halfway up the mountain could not be destroyed, then destroy the top of the mountain, so that the falling stones could be smashed on the catapults of their Angkor people, thus causing damage.

Everyone was admiring Zhao Rui's high idea, and then shot towards the positions on the top of those mountains.

Although Zhao Rui's idea is good, it is difficult for others to have the same accuracy as him except himself, and some of them can't hit the top of the mountain after several shells.

Zhao Rui destroyed the top of the mountain and achieved some effect, and occasionally he could hear the screams from the opposite side, so someone should have been injured.

Many of the catapults also stopped attacking, apparently from falling rocks.

However, there are still some fine catapults still attacking, probably because of the resources of gravel, they don't have to look for stones everywhere, but throw stones faster......

It's so infuriating, I know where the catapult is, but I can't hit it!

Zhao Rui couldn't help but think, if it was in modern times, what method would be used to crack down?

Immediately afterwards, Zhao Rui's eyes lit up instantly, yes! You can use mortars!

Oh my God, why did you forget about this simple but powerful weapon!

Mortars played a huge role in the war back then, simple to manufacture, cheap, but not inferior to other weapons, the most important thing is that its trajectory is a parabolic attack, which can give the enemy an unexpected blow, and it is also extremely suitable for the current occasion.

Aren't the catapults of the Angkor people just behind the mountain, and it is not difficult for mortars to hit them, and it can be said that they are endless!

Thinking of this, Zhao Rui couldn't help but slap his head hard, if he had known that he could make a mortar, what kind of artillery would he do, it was thick and stupid!

Zhao Rui thought about things, and he was also distracted, and the soldier next to him shouted loudly: "It's not good!" Be careful! ”

Ooh!

As soon as Zhao Rui looked up, he saw the boulder that was about to fall on top of his head, Zhao Gong and Arjuna were also frightened, the boulder came suddenly, and it was too late for them to knock Zhao Rui away.

For Zhao Rui, the boulder was no threat, and the strong talisman and golden body talisman he had just blessed still had time, so he was not afraid of such a falling stone attack at all.

And according to Zhao Rui's speed, it is too late to dodge now.

But in order not to cause damage to the city wall, Zhao Rui still decided to face it head-on.

"No ......"

"Oh my God......"

Zhao Rui didn't move, almost everyone screamed, seeing that Zhao Rui was about to die under the boulder!

But the next scene almost made everyone almost bite their tongues.

I saw Zhao Rui jump up violently, rushed towards the boulder, stretched out his palms at the same time, and forcibly changed the route of travel for the boulder, and the boulder was hit and fell diagonally under the city wall.

Oh, my God......

Is he a demon......

With the power of his flesh to block a boulder, this is a boulder that can destroy the city wall! It was dissolved by him so lightly.

This kind of power, or such skills, is not something that ordinary people can have!

After the surprise of the crowd, there was a round of applause.

"Awesome, awesome!"

"The prince's martial arts are invincible in the world!"

“……”

Everyone still needs to praise again, Zhao Rui hurriedly asked them to pay attention to the falling rocks, otherwise it would be a big loss to be stoned to death. They then retaliated from the top of the hill where the catapults were located, and although it was not very effective, it could also contain some of the attacks of the Angkor people.

The war is now in a state of anxiety, thinking that the Angkor people have elephant soldiers, and Arjuna's request to go out of the city to fight was also rejected by Zhao Rui, because the Angkor people have elephant soldiers, and the danger factor is too high for blind charge.

So the Angkor people were still throwing fire, and their side was also returning fire with a single cannon.

After all, there is a quantity of ammunition, and before the Angkor people did not show up, it was necessary to save some use, Zhao Rui saw it thoroughly, and felt that the most important thing now was to repair the city wall.

So Zhao Rui asked Zhao Gong to watch from above, and he went to the city to find the city guard officials in Jiaozhi, and asked them to immediately repair and strengthen the city wall.

For repairing the city wall, the Jiaozhi people were quite familiar with the road, they set up a cauldron in the city, boiled it with glutinous rice, and then mixed it with hydrated lime and limestone powder and sand and gravel, which became the necessary binder of the ancient city wall.

Although this adhesive is food-intensive, it is stronger than the adhesion of modern cement.

However, there is really no shortage of glutinous rice in Tuojiang Town, so a large amount of adhesive is made, and then poured on the surface of the city wall for reinforcement, and at the same time, some damaged places are repaired with bricks and adhesives.

Seeing that they repaired the city wall in such an orderly manner, Zhao Rui was also much relieved, plus this city is made of masonry, which is also completely suitable for this repair method.

Zhao Gong and Arjuna were found, and Zhao Rui ordered them to be stationed here, and he wanted to return to Wanya Prefecture to develop mortars.

Zhao Rui also specially instructed not to go out of the city to face the battle, everything was waiting for him to come back, after Aruna agreed, Zhao Rui did not delay, stepped into the carriage and headed for Wanya Prefecture.

However, this time the situation is a bit urgent, and it can't be studied slowly like before, Zhao Rui has to do his best to speed up the manufacturing, create a usable mortar, and go to Tuojiang Town to repel the Angkor people.

So Zhao Rui also accelerated his speed along the way.

Thinking of mortars, Zhao Rui's thinking also broadened suddenly, and the mood that had always wanted to make Makqin was not so strong.

Because in comparison, the manufacture of mortars is not known to be many times simpler than that of Makqin, and it is suitable for mass production and more armies.

At that time, which force would dare to shout with Zhao Rui, Zhao Rui has a mortar battalion, and he can directly bomb them into scum, which is not an exaggeration at all.

For mortars, Zhao Rui remembered that he also found information on the Internet and printed it out, but Zhao Rui didn't think about it at that time, he just felt that the more weapon information he could get, the better.

Although the drawings are still in Wanyazhou, Zhao Rui can still think of some details when he thinks about it carefully.

The structure of the mortar is very simple, the outside is the barrel, the bracket and the base are composed, which is not difficult, the most important thing is the production of ****.

The shell of the shell can be molded with molten steel, the shell of the fuse can be designed in the mode of snapping, and the firing device can be fired with a relatively large shotgun, which is not a problem for the workers of the bullet production line.

Zhao Rui now thinks that the only thing that is more difficult may be the structure of the fuze.

Modern mortars are used, but now there are no conditions to prepare nitroglycerin, so Zhao Rui still has to rely on the fuse structure on the drawings, which is also the practice before the ** was studied.

At the same time, the shell can't be **, it has to be purified black**, although the power is poor, but it doesn't matter, it can be done in batches, and when the number goes up, the power will make up for it.

Zhao Rui is no stranger to mortars, and he used to see the scene of mortar salvo fire in anti-Japanese war dramas, and that piece of explosion was covered, which was really cool.

At the same time, Zhao Rui also got inspiration from this incident, and originally thought that he could be invincible in the world by creating a Makqin machine gun, but now it seems to be right and wrong.

The mistake is that the experiment took too long, and it was certain that the mature Makqin machine gun could not be developed within the stage time, which would increase Zhao Rui's expenses to a certain extent, and at the same time, it had not yet formed the combat effectiveness it should have.

In this regard, Zhao Rui thought that he should first make a single-shot bolt-type rifle, and perhaps because of the speed of the cavalry of the Yuan army, Zhao Rui abandoned the idea of a single-shot rifle.

But now with the increase in population and troops, Zhao Rui feels that there is really no need to give up on it, because no matter how low-end the gun is, after having the base of troops, it will become a powerful combat force.

Moreover, they can hone the marksmanship of the soldiers for a while, and in the future, they can also master the automatic machine gun better!

The more Zhao Rui thought about it, the more excited he became, although he was still on the road, his heart had already flown to Wanya Prefecture.

But when passing by Shenglong, Chen Xuan, who learned of Zhao Rui's arrival, hurriedly chased after him to inquire about the battle situation, after Zhao Rui told him, he also deeply felt that it was not easy, and he was even more grateful for Zhao Rui's efforts, and promised to wait for the Angkor people in Tuojiang Town to drive away Zhao Rui and give Zhao Rui a big gift.

What kind of gift can Jiaozhi have? is already devastated by the war, Zhao Rui didn't pay attention to it at all, the reason why he is dealing with the Angkor people now is just for himself.

In Wanya Prefecture, there is a prosperous scene, the new season of rice is ripe, the city and outside the city are busy harvesting, small merchants and hawkers are also increasing, and even some farmers are too lazy to cook for a busy day, so they go to buy some ready-made food.

Now that agriculture is the foundation, Zhao Rui takes great care of the farmers, and the price of the grain has also increased, so their farmers spend some money to eat some stalls or something, and there is no economic pressure at all.

In addition, there are a lot of houses built outside Lin Shizhao's school, which is also caused by the surge in the population of studying, there is no imperial examination in Zhao Rui's territory, so this school has become a place that ordinary people yearn for, but anyone who has some money must send their children here, hoping to become Zhao Rui's subordinates in the future and get ahead.

Even if you don't want to be a civil official or a military general, it's good to be a worker. Not only is the salary very high, but also can get rid of the farm work facing the loess with their backs to the sky, which is also what people yearn for, and they feel that they have been promoted to a higher class if they are separated from farm work.

It would be nice if you could sit as a researcher.
