Seven huge cannonballs flew out of the muzzle of the cannon, like flying meteors, and rushed straight into the ranks of the Cochins.

Two of the bullets happened to hit the middle of the two groups of return guns, and those return guns were too close, and then the return guns immediately turned into fragments, and the fragments fell to the ground.

In the past, because of the angle and distance, there were more wounded, but now because Zhao Rui opened the cannon on the ground, the penetration was greatly enhanced, and the Jiaozhi soldiers narrowed the distance, so several other shells rushed straight into the crowd.

The Jiaozhi people were immediately stunned by the power of Zhao Rui's artillery, and they were still preparing for the return cannon this time, the artillery on Zhao Rui's side had already been launched, and it was easy to understand that the speed was faster, after all, the Song people had not used firearms for a day or two, but such a huge power had never been seen before.

Jiaozhi immediately lost a lot of troops, and the Jiaozhi people finally restored order amid the shouts of the commander, and were about to reload the return cannon, but the artillery at the opposite city gate was fired again!

"Boom, boom, boom......"

"Ahh Run! ”

"Be careful!"

The frightened Jiaozhi people soon became a mess, and their lives were at stake, and no one had the intention to fight back, and most of them ran away in an instant.

Although the commander was still shouting for everyone to go back, he himself was desperately running to the rear.

"Boom, boom! Whoa......"

This artillery immediately reduced the strength of Jiaozhi a lot, and also knocked down a lot of return artillery, now there are few intact return cannons left, Jiaozhi people fell into an embarrassing situation, want to go back and are afraid of shelling, but even if you go to operate those few return guns, you can't form any effective attack on Langjiang City.

The commander of the Cochin Army turned to look back, gritting his teeth with hatred, but his heart was finally occupied by fear, and he stomped his feet and said, "The whole army retreats!" ”

In this way, more than 30,000 people became more than 20,000, and even the rest of the return artillery was not needed, and the army fled in a hurry.

In fact, Jiaozhi didn't think about attacking Zhao Rui in the near future, because the Angkor people really didn't break their promise, and had already sent a huge number of elephant soldiers to attack the border front of Jiaozhi, and at the same time, there were suddenly well-armed Cham people in the south to harass, and the emperor Chen Jiong, as the monarch, was really miserable.

However, at this time, an envoy from the Yuan Dynasty went south from Dali to meet Chen Jiong, saying that Zhao Rui was their common enemy, and if Jiaozhi was willing to send troops, then the Yuan Dynasty could provide the most advanced return artillery as support.

At first, Chen Jiong did not agree, but after seeing the power of the Huihui artillery demonstration, he squeezed out the military strength of more than 30,000 people and went straight to Langjiang Mansion.

However, in the end, Chen Jiong still did not get the fruits of victory, and could only taste the fruits of defeat......

Zhao Rui is he a monster, after several battles, Jiaozhi has not won once, this ...... This doesn't make sense!

The envoy of the Yuan Dynasty had been living in the palace waiting for news, and when he heard that the army had returned, he hurriedly went to Chen Jiong to ask for news.

Contact Jiaozhi to launch an attack on Zhao Rui, which is one of the strategies of the Yuan army, the coal yard was unable to attack by Zhao Rui's strength to hold the terrain, and the use of troops against the Southern Song Dynasty reached a critical moment, so he wanted to win over Jiaozhi to strike at Zhao Rui's hinterland.

Unexpectedly, with the help of the latest return cannon, the Jiaozhi people also failed. This couldn't help but make the envoys of the Yuan Dynasty feel that the people of the Southern Barbarians were unreliable.

But no matter how many Jiaozhi people died, it had nothing to do with the Yuan Dynasty, anyway, the Yuan Dynasty had nothing to lose.

"In that case, the Emperor Taishang will bring me all the return cannons, and I will also go back to restore my life."

"No ......" Chen Jiong's face was a little ugly.

"What's gone, what's the point?" The envoy of the Yuan Dynasty stood up in surprise, and already had some bad premonitions in his heart.

"It was said that Zhao Rui used artillery, and those return cannons were destroyed." Chen Jiong's voice was full of helplessness, knowing that this time was in trouble, and it was likely to offend the Yuan Dynasty.

"What!"

The messenger's voice became sharper: "Do you know how many taels of silver a new type of return cannon costs? Rise? I gave you fifty planes, and now I haven't brought any of them back, how can you let me go back and explain! ”

Of course, it is impossible to have one, and the envoys of the Yuan Dynasty are now speculating whether the Jiaozhi people are greedy for the power of the return cannon, so they are greedy for ink?

"Give the silver, 200,000 taels each, a total of 10 million taels!" The envoy of the Yuan Dynasty said angrily.

"I ...... I don't have that much silver......"

Chen Jiong is uncomfortable, he has been fighting one after another recently, and he is consuming a lot of silver all the time, fighting is fighting money, and now there are really no 10 million taels of silver in the treasury.

"Humph! Boldly cross, you also dare to covet our Dayuan's things, wait, you Chen Dynasty will pay a heavy price! ”

The envoy determined that Jiaozhi had deducted the return cannon and did not return it, and left angrily, Chen Jiong was speechless for a long time in the back.

Fifty return guns are gone, what else is there to say......

After a long time, Chen Jiong relieved himself and shouted outward: "Someone! Behead me the commander who just asked for forgiveness from Jiang Mansion! Raid the house! And all the doors! His mother's! ”

Chen Jiong was so angry that he kicked over the coffee table, and the precious porcelain bowl from the Song Dynasty was smashed to pieces......

With this dirty defeat, the Chen Dynasty had a harder time, it used to have to deal with enemies on both sides of the southwest, and now there are coalition forces of the Yuan Dynasty and Dali in the north to invade, and Zhao Rui in the east is more like a beast, waiting for the opportunity to be eyed, Jiaozhi will fall into a situation from which he will never recover.

And Zhao Rui didn't have the slightest intention of dealing with Jiaozhi now, but they were too unlucky, just in time to test the artillery.

Zhao Rui also understands that it is meaningless to conquer by force alone, you can conquer others by force, and others can also rely on force to retake them.

So what is the royal road to conquest, that is, advanced productivity, when Zhao Rui's high-quality and advanced products occupy the world at low prices, it will almost occupy the whole world.

But at that time, we have to print our own currency, and then use the exchange rate with a large difference to completely control each country, so that people in all countries will work for us!

Remembering the progress of the smelting work, Zhao Rui immediately went to Wanya Prefecture, and Wanya Prefecture, which had not been here for a long time, had undergone earth-shaking changes.

The most intuitive point is that the population has become larger, and the streets and alleys are full of walking crowds, no wonder Zhang Zhennan proposed to make a plan to expand the city before, Zhao Rui agreed that it was completely in trust, but what he saw on the street today, Zhao Rui also understood that the city was really about to be overcrowded.

The second is that the buildings in the city are more dense, but with Zhao Rui's early planning, there is no messy construction, so it still looks relatively neat and orderly.

The market is full of shops and crowds, and what Zhao Rui particularly noticed is that the number of children is significantly more than before, which may be a stable production and life, bringing a lasting and stable economic source, so the birth rate of people's children has also greatly increased.

Zhao Rui felt good after walking around, a bit of a prosperous city, and the Song people and Jiaozhi people lived together, and did not find any ugly manifestations such as racial discrimination.

When he arrived at the smelting center near the mining area, Wei Lu heard that Zhao Rui was coming, and hurriedly greeted him, who was only a homeless blacksmith in the past, but now he has grown into the person in charge of the entire smelting center.

After inquiry, Zhao Rui learned that Wei Lu had been referring to the theoretical books and was constantly improving the technology of the furnace, although some places are not very clear now, but on the whole it is still developing towards a good trend.

Then Zhao Rui specifically asked about the progress of the steam engine, and Wei Lu was a little embarrassed when he arrived at this question, saying that the experiment was underway, and it might take some time to produce results.

Zhao Rui still understands the difficulty of this aspect, the original steam engine was invented for pumping water from coal mines, and he now asked Wei Lu to make an improved steam engine, which can be regarded as skipping a lot of stages, so he must now do his own experiments to strengthen his understanding of the technical theory of the steam engine.

So Zhao Rui comforted him a few words, telling him not to worry, not to accumulate steps to thousands of miles, let him understand a little bit every day, and there will always be a day when he will be able to understand it.

As for the simplified Chinese characters on the books, Zhao Rui has already taught Lin Shizhao and asked him to publish books that are simple and traditional, which is a great honor for Lin Shizhao, who is not very good at reading, he never dreamed that he would be able to publish his own book one day, although the content was taught to him by Zhao Rui.

This book greatly facilitates the understanding of modern materials by technicians, but knowledge is never achieved overnight, but slowly accumulated, but with the passage of time, people's understanding of science is constantly improving.

Because of the publication of the book, Lin Shizhao opened the first public enlightenment school in Zhao Rui's territory in Wanya Prefecture at the request of everyone, teaching children during the day and adults at night, all in simplified characters, which reduced the difficulty of reading and writing to a certain extent, and achieved good results.

You must know that after the liberation of later generations, the eradication of illiteracy was achieved by relying on such "secret tricks" as simplified Chinese characters.

Zhao Rui was also in favor of the construction of this school at the beginning, and now many of the recruits are about ten years old, and after they are literate, Zhao Rui is ready to train another group of lecturers to teach them mathematics, physics and chemistry, for the university Zhao Rui does not know, but the knowledge before high school, he still fully understands, and it is not difficult to teach the ancients.
