Two days have passed in a blink of an eye, and in the past two days, Fu Jian has been leading craftsmen to build the return cannon, and the building procedure of the return cannon is not difficult, and in two days, Fu Jian led people to build more than a dozen return cannons, which are more than enough for attacking the Taishou Mansion.

"Boom! Rumble! ”

Beiyan had already ordered people to prepare a large number of boulders, and after the return cannon was built, he wanted to see the power of the return cannon.

Huge boulders streaked across the sky and landed on the ground with a rumbling sound.

Looking at the boulder that had been embedded in the ground, Bei Yan couldn't help but be overjoyed, clapped his palms and exclaimed: "It's really worthy of being a return cannon, the power is so great, with these ten return cannons, Gongsun Yuan's Taishou Mansion can be broken overnight!"

Pull this thing outside the Taishou Mansion, before sunset today, you must break through the Taishou Mansion, so as not to have too many dreams at night! ”

Taishou Fuzhong.

Gongsun Yuan walked back and forth in the main hall, looking a little irritable.

Under normal circumstances, the longer the time dragged on, the more favorable the situation would be for Gongsun Yuan, because other soldiers and horses in Liaodong would rush to support when they got the news.

As for Beiyan, he should be desperately attacking the city, striving to break through the Taishou Mansion before the reinforcements arrive.

However, this was not the case, and not only did not attack the city, but did not take any action, and there was no movement for two days.

In this case, it is definitely not that Bei Yan gave up and accepted his fate, but everyone knows that Bei Yan must be brewing a big conspiracy.

Unknown conspiracies are the most terrifying, because you never know what you will face next.

Gongsun Yuan spun around, sat down with one butt, slapped the table with a slap, and shouted, "What does this Beiyan want to do? ”

Gongsun Yuan's temper was not calm enough, and in the face of unknown enemies, the more he thought about it, the more afraid he became, and the whole person seemed a little crazy.

Wuqiu Xiu on the side persuaded: "Don't worry too much about Taishou, that humble is just a horseman, and he can't think of any strategy to attack." Maybe his soldiers and horses are already in chaos at the moment, and they are thinking about how to escape for their lives. ”

Needless to say, Qiu Xiu said so, but his face was also gloomy, and he was actually panicked in his heart.

At this time, a soldier hurriedly ran in: "Too guarded, it's not good, Beiyan is attacking again!" ”

Gongsun Yuan stood up suddenly when he heard this, and asked, "How did he come to attack?" What's different from before? ”

When the soldier heard this, he replied, "It's no different, it's just that a few trebuchets have been brought over." ”

Gongsun Yuan breathed a sigh of relief when he heard this, and the big stone that had accumulated in his chest finally fell, and laughed: "I thought about what kind of killing move this Beiyan had been thinking about these days, and it turned out that I went to build a trebuchet."

My wall is made of bricks, does he think that a few trebuchets will break my house? Let's go, go over and see, I'm going to see how he used a few trebuchets to break down my mansion! ”

Gongsun Yuan said and walked towards the city wall.

At this moment, Bei Yan has set up the return cannon with the help of Fu Jian and Luo Xian, and in order not to affect the use of the return gun, Bei Yan even ordered the demolition of some houses.

The ten return cannons were placed outside the south gate of the Taishou Mansion, aimed at the direction of the city gate.

There are a large number of boulders placed around, and the Liaodong army is holding shields, knives and guns, waiting for the city gate to be broken by the return artillery and rushing in.

When Gongsun Yuan came to the city wall, he couldn't help but breathe a sigh of relief when he saw that Bei Yan really didn't change the battle plan, but just a few more trebuchets.

Gongsun Yuan didn't recognize the return cannon at all, and thought that those were ordinary trebuchets.

The walls of his Taishoufu are made of blue bricks, and ordinary trebuchets can beat the small cities built by rammed earth, but they cannot break the walls of the blue bricks.

Even if it can be breached, it is not something that can be done in a day or two.

Gongsun Yuan stood at the head of the city and shouted at Bei Yan: "Bei Yan, I thought you were preparing some big killing weapons in the past two days, it turned out that you had built a few trebuchets, do you want to use these trebuchets to break through my Taishou Mansion?" ”

"Hahaha!" Bei Yan laughed when he heard this, the Huihui cannon had not yet been introduced to Liaodong, he naturally knew that Gongsun Yuan didn't recognize it, and pointed at the Huihui cannon and shouted: "Gongsun Yuan, you shallow guy, do you know what this is?" Look at me today, I will break your Taishou Mansion! ”

At this moment, Wuqiu Xiu also rushed to the head of the city.

He is a general of Wei and is well-informed, Gongsun Yuan does not recognize Hui Cannon, but Wu Qiu Xiu does.

Seeing that there were more than a dozen return cannons beside Bei Yan, Wu Qiuxiu sat on the ground with weak legs and a buttocks: "It's over...... Finished! How did this Beiyan know the method of building the return cannon? ”

Gongsun Yuan listened to Wu Qiu Xiu's words, sighed in his heart, grabbed Wu Qiu Xiu and said, "What did you say? You say those creepy trebuchets are return cannons? Did you read that right? ”

Although Gongsun Yuan had never seen the Huihui Cannon, he had also heard the name of the Huihui Cannon, and he thought about how many fortified cities in the Wei State were dangerous, and not all of them were broken under the attack of the Huihui Cannon.

If the trebuchets built by Beiyan were really return guns, he would only be able to build the walls of Taishoufu with blue bricks, at most a few stone bullets.

"It's really a return cannon, I've been ordered to build it before, I can't be wrong."

Wu Qiu Xiu was paralyzed on the ground, he had already accepted his fate, if nothing else, Gongsun Yuan would betray him in a while.

Sure enough, when Gongsun Yuan heard this, his face turned blue and white for a while, and he immediately pointed at Wuqiu Xiu and shouted: "Wuqiu envoy is not feeling well, you two will help you to take care of your life under the city, and you can't leave an inch." ”

Wuqiu Xiu let the soldiers help him to the city, and there was no resistance, he knew that Gongsun Yuan would betray him if he was in danger.

However, Gongsun Yuan didn't betray Wuqiu Xiu immediately, he had a trace of luck, maybe Bei Yan didn't take out the return cannon?

So Gongsun Yuan wanted to see how powerful the trebuchet was, and if the power of the trebuchet was really as legendary, it would not be too late for him to betray Gongsun Yuan.

Gongsun Yuan also walked down the city, and suddenly he thought of something.

Gongsun Yuan thought to himself: "I have never seen the return cannon, how can this humble Yan build the return cannon?" There were only two of them when the Han envoy came to call me, and it was impossible for their envoy to come to two, there must have been others.

Could it be that everyone else has fled, and it is they who persuaded the humble rebellion against me? ”

This Gongsun Yuan was not stupid, and soon thought of the whereabouts of the other members of the Han mission from the return cannon, and guessed the cause and effect.

"If the other members of the Great Han Mission are really under the command of Beiyan, then the two of them can be used!" Soon, Gongsun Yuan once again found a life-saving straw.
