On the third day of the siege of Gaowan City, the Zhao army began a tentative siege.

The sound of drums like thunder kept echoing in everyone's ears, and Li Mu stood on top of the tall chariot and watched his subordinates rush towards Gaowan City like a tide.

Siege is actually a very boring and long thing.

First of all, you have to find a way to solve all kinds of obstacles outside the city, such as moats and the like.

Secondly, it is necessary to get some heavy siege equipment, such as rushing towers, and of course, the most indispensable is the trebuchet.

After all these things are ready, then the besieging side will have to fill it with human lives.

From the beginning of the battle to the breach of the city, this is the stage where the besieging side suffers the heaviest casualties.

But when the city is breached, the deaths of the defenders will rise sharply.

In this era, looting and killing after entering the city has almost become a customary habit, the only difference is the severity of the looting and killing.

As a veteran, Li Mu certainly knows this.

So Li Mu didn't like the feeling of attacking the city very much.

Even if this situation has long been commonplace, when Li Mu saw his soldiers fall on the way to charge one by one, he still felt a little uncomfortable.

If there were no damn city walls, then the soldiers under Li Mu's command would not have to suffer so many casualties in vain.

This phase of the siege lasted a full ten days.

During these ten days, the Zhao army paid a huge price, and finally filled in the moat outside Gaowan City under the rain of arrows from the Qi army.

From this day on, the war entered a new phase.

Ladders, chariots, and other weapons that require close proximity to come in handy are finally starting to take effect.

In front of Li Mu, many trebuchets were exerting their might, and one after another boulders were thrown into the sky by trebuchets, and then bombarded towards Gaowan City in the distance.

Li Mu looked at these trebuchets silently, and a bold idea suddenly appeared in his heart.

"What if you could put the Heaven-Shaking Thunder into the trebuchet and then throw it into Gaowan City?"

After the end of the day's battle, Li Mu called the general who accompanied the army and explained his thoughts to the master.

After listening to Li Mu's thoughts, the master craftsman's gaze at Li Mu suddenly became quite strange.

Li Mu shrugged his shoulders: "Why, can't such an idea be realized?" ”

The master shook his head and hesitated for a moment before saying, "Actually...... The Metropolitan Governor does not know that the method mentioned by the Metropolitan Governor is already under development. ”

Li Mu was overjoyed and said, "When will it be developed?" ”

The master craftsman coughed and said, "The matter is confidential, so I can't explain it in detail." But what I can tell the Metropolitan Governor is that after the discussion of the Great Commander and all the great craftsmen, the conclusion is that it cannot be succeeded for the time being. ”

What Li Mu didn't know was that what Zhao Guoren was actually studying now was not what he thought about, but a more well-known weapon for later generations - artillery.

"The truth is only within the range of the cannon." This was proposed by Duke Otto von Bismarck, the first chancellor of the German Empire, in his famous iron-blooded speech.

In the era of hot weapons, artillery is undoubtedly the king of positional warfare, and it is impossible for Zhao Dan, as a traverser, not to know this.

Therefore, since the appearance of gunpowder, Zhao has invested a lot of manpower and material resources in this area.

However, due to the limitation of the level of knowledge, the research of artillery is still in an extremely rudimentary stage, and even a prototype has not been built, and the time to put it on the battlefield is even more difficult to look forward to.

Of course, Li Mu didn't know this, he said with some puzzlement: "Isn't it just a tool that throws the Heaven-Shaking Thunder into the city, is it so troublesome?" ”

In Li Mu's eyes, this earth-shattering thunder doesn't seem to be much different from a stone.

The master paused for a moment and said, "If the Grand Governor wants to throw the Heaven-Shaking Thunder into the city, it is not too difficult, and the length of the lead wire needs to be adjusted slightly. It's just that the landing point of the trebuchet and the time of detonation are really difficult to accurately match, and if the earth-shaking thunder is used like this, I am afraid it will be difficult to blow up the walls of Gaowan City. ”

Li Mu thought about it, but still insisted on his opinion: "No, it's better to try." Go and prepare, I hope to see a preliminary plan in three days. If you are not at ease, you can let the prisoners who are with you try to operate the trebuchet. ”

During the war years, everyone was precious, so almost every country would bring a large number of criminals with them when they went to war, and as long as these criminals could make meritorious contributions in the war, they could be exempted from crime or even promoted.

Li Mu's idea is actually very simple, even if he can't blow up the city wall, then when the earth-shaking thunder roars and explodes around the people of Qi, that feeling will definitely make the people of Qi very comfortable.

After all, the strongest army of the Qi army has been gathered in Gaowan City, as long as this army is defeated, then more than half of the battle to destroy Qi has basically been completed.

In order to achieve this goal as soon as possible, Li Mu is willing to try.

After sending off the master craftsman, Li Mu pondered for a long time and wrote a recital.

"The minister Li Mu presented himself to the king:

Since entering the Qi realm, the resistance encountered by the ministers has been very fierce, and even if they have passed through such small cities, with the elite of our army, it will take several days to overcome them.

The reason for this is that the ministers thought that it was because the officers and men of our army were complacent after destroying the Wei, Han, and Yan countries, and they were so proud that they did not do their best when they fought.

In addition, although the Qi State has been weak for 40 years, the Qi State has been inherited for hundreds of years, has always been the overlord of the East, and has experienced the restoration of Tiandan, so there are many patriots in the Qi State, and they are extremely brave when fighting, and they can often fight against the enemy, which is far from being comparable to the three kingdoms of Wei, Hanyan and Yan.

Chen is now fighting with the enemy general Zhou in Gao Wan, Zhou Fen can't hold out, although the minister is confident to overcome, but with the current battle situation, if you wait until you take Gao Wan and then conquer Linzi, I am afraid it will take a lot of time.

Therefore, the minister thought that the king might as well send another capable general to lead a partial army from the direction of Langya and Jucheng in the south of Qi to march towards Linzi in the north, so as to threaten Linzi from the south.

In this way, Zhou Fen will definitely take care of one and lose the other, and the Qi army will not attack and chaos, or will have a chance to defeat the Qi army quickly.

Minister Li Mu respectfully. ”

After finishing writing, Li Mu hesitated for a while.

If this letter is presented, will the king feel that this is an excuse for Li Mu to excuse his lack of ability?

After a short hesitation, Li Mu still took the fire paint, solemnly sealed it, and then called the captain of his personal guard.

"Quickly send someone to send this letter to the Handan Palace!"
