The ancient siege equipment was not replicated by later generations by just filming a historical drama. It is true that in the Middle Ages without industrialization and black gunpowder, it should be that there should be no shocking machinery.

But in fact, if you do not consider the development of productivity and switch to the same industrial economic foundation, you will find that many things are actually not as grand and refined as ancient people.

The main reason is that modern times do not have a accountability system, so everyone can fool as much as they can.

In ancient times, it was all responsible. For example, giant siege equipment such as chariots and storms that are now operating will be destroyed by the enemy, but if an accident occurs during normal operation, the craftsmen who manufacture will be arrested and beheaded.

Therefore, in this working state that regardless of cost and does not pay attention to the return on benefits, the durability and solidity of these things can naturally be imagined!

Li Qingyuan felt that even if he had full firepower, he would not have thought of destroying a giant siege equipment about 30 meters high and about 50 meters long without thirty seconds.

If this thing can be brought to the Naruto World, it feels like it can be directly transformed into a tool to capture tailed beasts!

A huge rock more than one person tall was thrown out by the Thunderbolt cart. If the shock wave and explosion damage were not considered, the power of this thing was actually stronger than that of an ordinary howitzer.

After all, several tons of stones ejected out at super high speed. If it is purely physical damage, even a monster that claims to be invulnerable to swords and guns will probably be directly shot into meat sauce.

Yu Tancheng Wall seemed in danger under the siege of various siege equipment. However, Cao Ang, as Cao Cao's most valued son, was not an ordinary person. In addition, Cao Hong and Cao Ren were also very powerful. The three of them stood on the city wall and tried hard to command the soldiers to counterattack with various siege equipment. For a moment, the two sides fought so hard that they were going back and forth.

The battle between the two sides lasted for five or six days, and Yu Tancheng Wall was already smashed with holes and was almost unable to hold on!

After all, the city wall of Yu Tan County was just broken by Cao Ang, and even if it was urgently repaired, it would be useless. Being able to last so many days is considered to be the hard work of the city guarding soldiers.

"As long as another attack tomorrow morning, we can defeat the East City Wall. At that time, the morale of the enemy will definitely be greatly damaged. At most, we can completely defeat Yu Tan County tomorrow afternoon!"

The marching tent was brightly lit, and senior officials from Qingzhou were holding emergency meetings overnight.

Chen Qun pointed to the transformed Yutan County City model and analyzed.

"How many enemy troops should be left in the city?"

Li Qingyuan sat in the main seat and thought about it and asked.

"According to the captives reported, there should be more than 45,000 enemies in Tancheng, but after these days of consumption, it is estimated that there should be less than 40,000."

Wei Yan answered hurriedly.

Wei Yan, the unlucky guy, has always wanted to make contributions. After all, Zhou Tai, the guy who defected to him, has become a miscellaneous general, and he is still a captain, which makes Wei Yan, who claims to be a regular army, feel very dissatisfied.

Unfortunately, Zhou Tai not only stopped Zhang Fei continuously, but also joined Jiang Qin to pay off all the pirates near the East China Sea. Regardless of whether it was in terms of strength or military merit, he steadily suppressed him.

Wei Yan just has a bad temper and has a low EQ, but he is not the kind of person who is irresistible. Zhou Tai is better than him in everything, so although he is jealous of Zhou Tai's contribution, he does not have any resentment or anger.

"There are still 40,000 people? Where are the remaining soldiers of Cao Ang?"

"According to the spies' returns, there were about 20,000 troops stationed in the county under Yutan County, but now they all retreated to Xiaoguan, which borders Yanzhou under the command of Cao Cao's army. It is obvious that the other party wanted to defend Xiaoguan's portal so that Cao Cao's rescue army could come quickly."

I have to say that Cao Cao is indeed full of talents. Cao Hong and Cao Ren and the other guys resisted the siege of their four times their army. The guy Li Dian was able to seize Xiao Guan as quickly as possible, which was indeed beyond his expectations.

Although he seems to have a lot of talents under his command now, whether it is Chen Qun or Xun Biao, he is just a specialist. Lu Su is a top expert in diplomacy and internal affairs, but it is still a bit short of planning and controlling the overall situation.

As for Chen Deng?

This guy will only consider the interests of the Chen family in Guangling. Unless he can dominate the Central Plains with a sweeping force, he will reveal the possibility of unifying the world. Otherwise, Chen Deng would at most beat the side drums, and it would be impossible to expect him to coordinate the overall situation.

Besides, although Chen Deng is not weak, he always feels that he is a little bit short of playing against those top national players.

It may be an identity halo bonus!

"Is there any news from Yanzhou?"

Li Qingyuan was thinking about how to get a national player to coordinate the overall situation and asked.

In fact, strictly speaking, Aning can be used to be the chief military advisor for himself. However, Aning likes to stumble, and the other hand, it is not easy to see Aning talk about one big thing, but in fact, when it is really the turn to operate, there will always be a situation where he is very arrogant and low.

There is no way. After all, Aning is not a person from this world. She doesn’t understand many common sense issues at all, just like herself!

Besides, compared to asking Aning to study various strategies every day, Li Qingyuan has more important things to do.

"Our spies in Yanzhou have not yet received any rewards, because our dark web has not been arranged there yet. However, according to Cao Cao's actions last month, even if he wants to come to rescue Cao Ang, it is absolutely not enough to have half a month."

Aning heard his question and quickly replied.

That's right, since becoming the governor of Qingzhou, Li Qingyuan ordered Aning to establish a spy agency to be responsible for investigating various intelligences.

As a person in power, if you don’t have your own independent eyes and eyes, you will fall into a very passive situation.

Moreover, those in charge of the secret service must be 100% loyal and smart, and they must be extremely capable. Apart from Aning, there is no other suitable candidate!

Guan Yu was sent back to Xuchang by Liu Bei seven days ago. If Cao Cao had started to consolidate his army from then on, he would have almost arrived at Xiaoguan now.

But it is obvious that this is impossible. The reason why Cao Cao did not come to Xuzhou in person was because he and Lu Bu were fighting. Even if he got the news, Cao Cao stopped his troops and rushed back from Sili. It would take as long as half a month.

"In other words, we can't get around and fight for help?"

After listening to the report from everyone under his command, Li Qingyuan asked helplessly.

It also requires skills to surround the points and attack support. If Cao Cao's army can arrive in one or two days, then it is just right to set up a plan to wait for work.
