After a while, Li Changkong stepped into the warm pavilion, and Liu Yu saw this and said, "Come late at night, there must be something important, let's talk about it." ”

"Didn't Your Majesty say last time that the Northern Yuan army was strong because there was a giant trebuchet that could break through the walls of Shanhaiguan?"

When Liu Yu heard this, his pupils suddenly contracted, his eyes widened, and he said, "Lao Li, don't tell me, have you found a way to restrain the giant trebuchet?" ”

Hearing this, Li Changkong nodded.

This understatement set off a storm in Liu Yu's heart.

God can see mercy, they just said it casually at the beginning, but they didn't expect Li Changkong to really do it.

It's a giant trebuchet, after all!

It is the pinnacle of countless skilled craftsmen, and even the masters of the mechanism who have spent years of hard work!

If you want to fight it, you need an equally giant machine!

However, the construction of such a large equipment consumes countless manpower and material resources.

Crucially, they don't have drawings!

With such a huge device, the drawings are often very complicated, and non-machine masters can't do it!

Although Lao Li is powerful, I haven't heard that he also has research on the organs!

So Liu Yu didn't have much hope for this, and Li Changkong never mentioned it later, and over time, he forgot about it.

Who would have thought that Li Changkong gave him a huge surprise today!

"What is it that can fight against a giant trebuchet?"

Liu Yu had never seen a giant trebuchet, but he had been to Shanhaiguan when he was a child.

is so strong, known as the top three in the world, and even has the qualification to compete for the first place!

The thickness of its walls is unparalleled!

No matter how powerful a martial artist is, he can't move a single inch of it with all his might.

The impact of the giant battering ram surrounded by several people is only a slight shaking!

But such a strong city wall was deflated in front of the giant trebuchet.

You can see the benefits of giant trebuchets!

What did Lao Li create that could compete with it?

For a while, Liu Yu's curiosity was brought to the top!

"Black powder!" Li Changkong paused word by word and spit out three words.

"Black powder?"

"What is this?" Liu Yu frowned slightly, slightly surprised. Obviously, this is a completely foreign term to him.

"An explosive thing! With the right proportions, it is entirely possible to blow up the giant trebuchet by surprise! ”

"This thing sounds very complicated, I'm afraid it's not easy to make, right?" When Liu Yu heard this, his brows furrowed slightly.

When Li Changkong heard this, he nodded, affirming his statement: "However, the minister found a great talent of this Dao, who knew nothing about this Dao before, and he had only studied it for more than a month, but he was already able to prepare a powerful black powder!" ”

"Good, good! Lao Li, you are really my lucky star! How can I find such a great talent! I want to reuse it, what do you think? ”

"The minister's idea is to let him follow the army north first, and deploy black powder at any time."

"Black powder is a battlefield weapon, not only for blowing up giant trebuchets, but for many other purposes. If the commanders of the three armies have more active brains, it is not impossible to use them to deal with the Northern Yuan wolf cavalry! ”

"It's a pity that this product is temporarily limited by technology and cannot be mass-produced, and the relevant manpower is also insufficient!"

"After this battle is over, Your Majesty can reward him with an official position for his merits, and make him hold a lecture to recruit this good man!"

"Not for mass production, at least... Stock up on a little more, just in case! ”

Hearing this, Liu Yu nodded, and said, "It's worthy of Lao Li, if you really know everything, you will do what you say." ”

"In this way, I am afraid that the victory rate will rise by two percent." Liu Yu was overjoyed.

When Li Changkong heard this, he frowned slightly and shook his head.

"Your Majesty, don't think so!"

"Why?"

"The name of Tuoba Heavenly Khan resounded throughout the Northern Yuan, and even the famous generals of Great Chu and Western Qin couldn't help but admire it when they heard it!"

"This person is not easy to match!"

"The black powder plan can only be used once!"

"If you can't blow up the giant trebuchet, if you want to use the wisdom of Tuoba Heavenly Khan, the Zhenbei Army will have no chance at that time!"

"In addition, even if we can successfully blow up the giant trebuchet, our army is still at an absolute disadvantage in numbers."

"The situation is still not optimistic."

Hearing Li Changkong say this, Liu Yu frowned slightly, and said a little puzzled: "Why is this so?" Could this person really be a god? ”

When Li Changkong heard this, he shook his head helplessly and said, "Your Majesty, the three divisions of the Northern Yuan Dynasty have been divided for a long time, and they have been fighting with each other for nearly a thousand years!" ”

"However, Tuoba Heavenly Khan is the only one who dominates the three tribes!"

"And in just two years!"

"Such an achievement, not to mention that there is no one who will come after, at least it is unprecedented!"

"Besides, our Zhongshan King, a young man, has experienced no less than a thousand battles in his life!"

"It can be described as a famous general in the world!"

"Even in the face of the famous generals of Great Chu and Western Qin, I'm afraid it's not false at all!"

"But in front of Tuoba Heavenly Khan, he has been suppressed repeatedly, and even asked for help from Qiandu City many times!"

"With all this, can't Your Majesty see the horror of Tuoba Heavenly Khan?"

When Liu Yu heard this, he silently closed his eyes, sighed, and said, "What can I do!" ”

He thought that he had already looked up to this master of the grassland high enough, but he didn't think about it, he still underestimated it!

"Haven't we all sent 200,000 reinforcements? With such a lineup, coupled with the leadership of King Zhongshan and Dingguo Gong, and the mountains and seas Xiongguan and black powder to rely on, can't you even stick to the city? Liu Yu was unwilling.

"Difficult!" Li Changkong also sighed and said, "Your Majesty, have you forgotten that our 200,000 reinforcements are just recruits!" ”

"What is the place in the north? That's a meat grinder! ”

"If the recruits go to such places, the survival rate is probably no more than 20%!"

"After all, 200,000 reinforcements can't even compare to 50,000 elite soldiers!"

"As for the mountains and seas Xiongguan and black powder, of course, they are our hole cards, but Tuoba Tianhan knows that Liu Jing's rebellion has failed, why does he still bite my Daqian Northern Frontier?"

"If you don't rely on it, I'm afraid it won't be like this!"

"All in all, it's not a big win."

"What do you think you should do?" Li Changkong's words, Liu Yu's temples hurt.

He originally thought that the odds of victory were not small, but who would have thought that he might not even be able to defend against it.

This Northern Yuan, this Tuoba Heavenly Khan, is really ...... Alas!

"Western Jin Dynasty, 90,000 elite soldiers, 10,000 iron cavalry!" Li Changkong's eyes shot out of essence, and his words were conclusive.

From beginning to end, the 100,000 reinforcements of the Western Jin Dynasty were all in his urn!

It's impossible to let go.

However, when Liu Yu heard this, he was immediately anxious, and waved his big hand: "No, absolutely not!" ”

"Whether it's the land west of the river, or your old Li, I don't want to let it!"

However, Li Changkong changed his words: "Your Majesty, that was the previous condition, and now... Not necessarily! ”
