At the mouth of the Yalu River, thousands of warships crowded together, and the battle of more than 200,000 troops changed the color of the entire estuary.

"Spread the word to Li Ji and retreat until they all return to the Yalu River!"

On the top of a mountain, Li Er and a group of generals nervously watched the battle below, while Li Yi and Li Jing sat at both ends of a sand table, and the game was over.

"If you enter the Yalu River, you can temporarily stop the coalition from coming in, but if the Goguryeo army comes from behind, you will be attacked from behind." Li Jing pointed to the sand table and said in a deep voice.

"They didn't dare come over." Li Yi took out three black stones in his hand and put them on the sand table.

"We still have four points of explosives, and we can take out one of the explosives to raid the Black Bone City, not for meritorious service, but for deterrence, as long as they dare not go out of the city. The other two ordered a warship to be stationed on the Yalu River, and as long as the Goguryeo army moved, let them listen to the sound, even if it could not kill them, it could scare them into not daring to move. ”

Li Jing looked up suspiciously and asked. "Four points of explosives, you used three points at once, we still have two cities of black bones and Pyongyang, is it enough?"

"Grandfather, before there were no explosives, our Tang army attacked the city, but it was never afraid, why now that there are explosives, you are muttering? This explosive does not necessarily have to be sieged, he can use it as long as he needs it. ”

Li Jing was stunned and smiled bitterly. "You're right, the invincible military might that my Tang Army relies on. This explosive, it's better to have him, and it doesn't hurt if you don't have it, but I'm obsessed. ”

"More than a pharmacist? I'm not the same, since I had explosives, I won't fight for a while. ”

Li Er sent all the people around him out according to Li Yi's intentions, while watching the "chess game" of the grandfather and grandson.

"Your Majesty, this explosive is an important weapon of the country, and it cannot be easily shown, after this time, my Datang still needs to defend the explosives tightly, as long as the secret recipe of the explosives is not leaked, my Datang frontier will be stable forever." Li Yi was born and persuaded.

"Why don't I know? However, how can anyone in this world always keep secrets? This gunpowder formula will be leaked sooner or later, and at that time, what should I do with Datang? ”

"Haha, Your Majesty, this society is developing, the times are progressing, we used bronze tools before, then there were iron tools, and then there were hundreds of steel, so that now gunpowder and explosives, in the future, it is likely that there will be more weapons that we can't imagine, so the current explosives are definitely not the ultimate weapons. Since we can't guarantee to keep this secret, then it's okay to guarantee the lead, as long as you can do it when others use iron swords, we can use steel swords, then I, Datang, will still be safe. ”

Li Er pondered Li Yi's words carefully, and suddenly realized that he had been suffering from gains and losses for explosives before, just like a poor man who suddenly picked up a huge gold ingot, he must be hiding for fear of stealing, carrying for fear of losing. If you can use this gold ingots to earn more wealth, you will no longer have to suffer from gains and losses for gold ingots.

Thinking through everything, Li Er was suddenly refreshed and had a new understanding of everything in front of him.

"Li Yi, the important minister of the country!"

Suddenly, Li Er solemnly gave Li Yi such an evaluation.

Li Yi was suddenly a little flattered. Li Jingdu hurriedly stood up and refused for Li Yi.

was stopped by Li Er waving his hand. "Okay, you grandparents and grandchildren, everything is fine, but you are too cautious. At the beginning, in order to avoid suspicion, he resigned from all his positions and made a military academy sacrificial wine. As for Li Yi, he doesn't even do it. I really know your worries, I understand them, and I won't stop them, but you can't stop me from rewarding you. ”

When the ancestors and grandsons heard this, they were both moved to salute Li Ershen, and immediately sat down again.

"Okay, the big war is coming, let's talk about the war." Li Er saw that Li Ji had already led the army into the Yalu River, and asked, "Li Yi, it's time for you to make a move, right?" Explosives can only block for a while, and it is better to solve it as soon as possible for this coalition naval division. ”

"Obey." Li Yi should snort and no longer hide it. "Your Majesty, when the minister was in Jiangnan, he ordered them to renovate the warships, and later, through the efforts of a group of craftsmen, they made six ironclad ships, these ships are not only strong and collision-resistant, but also have a very high speed, what the minister means is that if these six ironclad ships are used as arrows, let our navy make arrows, as long as we can withstand their offensive, then this arrow can easily penetrate the warships of the coalition sailors, no more, as long as it goes back and forth twice, the coalition sailors can be torn apart by the impact, and when the time comes, they will also be slaughtered by us."

In the era when there was no artillery, the naval divisions often collided with each other or fought in close quarters, and the quality of the ships of the Tang Army was originally much better than that of the coalition warships, but the number of coalition warships was large, so the Tang Army lacked an arrow, and now with the arrow of the ironclad ship, the Tang Army could gallop at full speed on this vast sea, and the warships of the coalition naval division could not block the impact of the ironclad ships.

And that's exactly what happened.

After listening to Li Yi's suggestion, Li Er gave the order directly.

The six ironclad ships were taken by Li Yi to the vicinity of the Yalu River, and there were a thousand Cao Gang on board, and the person at the head was Li Zhen, who had been training for half a year as a sailor, and today, it was finally useful.

Li Zhen's appearance surprised and delighted Li Ji.

Li Zhen has actually always been a pimple in Li Ji's heart, and he has always been worried about it and can't let it go.

Especially after he learned that Li Zhen was a dart master, he was angry and fell seriously ill, Li Zhen was his only son, how could he allow Li Zhen to be such a lowly dart master?

But Li Zhenyuan is in Jiangnan, and even if Li Ji wants to manage it, he can't do it.

He thought that Li Zhen's generation would be so wasted.

Even, he thought about giving Li Zhen a reward for the credit of this expedition, not a big reward, pity the hearts of parents all over the world, he only asked Li Zhen to live a safe life.

But he never thought that Li Zhen would give him such a big surprise, looking at the six ironclad ships that shocked him and the man standing on the ironclad ship like a gun, Li Ji had mixed feelings for a while.

"Dad, the child is not filial!"

After Li Zhen led the ironclad ship to the vicinity of Li Ji's ship, Li Zhen knelt down for Li Ji with a plop, and a thousand words in his stomach turned into these five words in the end.

Li Ji was stunned for a long time, and suddenly looked up to the sky and smiled. "Aha, good, good! Zhen'er, get up, you are good, you are not ashamed of your father! ”

When Li Zhen heard this, he suddenly burst into tears with excitement, he had been waiting for this sentence for too long.
