The city wall of Xijin Mansion is also equipped with transport tools such as pulley booms, which are probably to facilitate the transportation of city defense equipment, the small pulley boom makes Peng Qi happy, and Zhao Zhen observes the speed and bearing weight of the pulley on the side, the huge rolling stone sassage wood is easily lifted by Peng Qi under the action of the pulley, and it is more convenient to install a winch.

The crossbow arrows on the city wall were neatly stacked in a small cart, and the small cart was placed in a special corridor, and once the battle began, a soldier's cart with good feet would run wildly on the city wall, and where there was a shortage of arrows...... There are no less than 20 such corridors on the walls of Xijin Mansion.

Its most important role is not only to store crossbow arrows, but also to store powerful gunpowder shells.

Today's gunpowder has been improved by the Ordnance Department to purify a lot, and at the same time, the original powdered gunpowder has been changed to granular, not to look at this small change, but to increase its air saturation, making the explosive power of the gunpowder bullet more powerful and faster.

Crossbow arrows can be placed in the corridor, and gunpowder bullets can also be placed, and the lethality of gunpowder bullets added to broken iron is also more amazing, this is the earliest fragmentation grenade, which is particularly sharp in the defense of the city, no need to do anything like aiming and estimating, light the fuse, throw it into the pile, and all the problems are solved...... If one doesn't work, then two or more.

Of course, the number of gunpowder bullets is a problem, Zhao Zhen thinks that a side hall should be opened in the palace of Xijin Mansion to make gunpowder bullets, in case of emergency, to make gunpowder bullets in the palace, who else dares to be careless?

The only question that puzzled Peng Qi had bothered him for a long time, and today when he saw that the official family looked good, he tentatively asked: "Official, you see that we have made the Xijin Mansion impregnable, but what if the Liao people don't come?" ”

Zhao Zhen watched the soldiers carry out daily maintenance and oil on the Eight Bull Crossbows, and said without looking back: "Do you say that it is simpler than the city near Xijin Mansion?" ”

Peng Qi nodded as a matter of course and said: "This is nature, Liangxiang, Miaoyin, and Shunzhou are much easier to fight than Xijin Mansion, if these three places are captured, Xijin Mansion will inevitably be surrounded by the Liao people!" ”

Zhao Zhen glanced at Peng Qi, but he didn't expect him to see the trick, and after a little thought, he knew that this product was going the way of the Cao family, and he went to Cao Wei all day long, and Song Xiaoyi had already said to himself many times.

"I learned a lot from Cao Wei, but you forgot one thing, the first iron law on the battlefield, capture the thief and capture the king first! If you don't use this sharp spirit to take Xijin Mansion, you will instead capture these small cities you said, and the city will change hands in a blink of an eye.

How can the Liao people not know the power of my Great Song artillery? Even if the small city is taken, it will be in danger under the artillery of my Great Song Dynasty, what difference does it make to take it or not! Could it be that he Yelu Zhenzong planned to surround my 260,000 army with 200,000 troops? ”

Peng Qi suddenly found that after the official family said this, he seemed to be used by Cao Wei, no wonder this old man would talk to him about military affairs when he was fine, it turned out that he had other plans, thinking of Cao Wei's explanation, Peng Qi began to hesitate.

Zhao Zhen looked at Peng Qi who was in a daze, patted him and smiled: "Think about a few more whys in the future, don't always be led by others, and be happy to be sold for a long time." ”

Peng Qi smiled bitterly and said: "Cao Shumi, this has captured my curiosity, and I also want to know why the Liao people will definitely attack Xijin Mansion......"

Zhao Zhen pulled the winch hard to wind the Ba Niu crossbow, and the guards on the side stood cautiously on the side, and even wanted to step forward to help but were glared back by Zhao Zhen.

"Curiosity...... Kill the cat! If you don't know something, go ask Di Qing, he will naturally explain the reason to you, don't get together with an old fox like Cao Wei! After a long time, I haven't learned anything else, but it is a great skill to be scheming. ”

Peng Qi stretched out his hand and pulled up the rope hook on the eight-bull crossbow to string the crossbow well, although this eight-bull crossbow is theoretically good to be wound by one person, but it must be equipped with two people on the battlefield, otherwise the speed is too slow and too physically demanding.

"The last general was worried about Di Qing, so he deliberately didn't dare to get too close to him, for fear of causing trouble for him......

Peng Qi's words made Zhao Zhen's eyes sharp, and a chill spread from Peng Qi's tail vertebrae to the back of his head.

"Someone wants to hit him again? It seems that what I said is still not clear enough! There are always people who want to challenge my patience and temper! Is Cao Wei already so unscrupulous with his identity as a general? ”

Peng Qi said with a smile: "How can his old fox have such courage, even if he has, he has been dispelled, and the last general has heard him say before: It is really good to do well in Jiangmen, and he will never be able to stand out in front of His Majesty just by suppressing others!" ”

Zhao Zhen, as the emperor, knew how well the things in the officialdom felt, and glanced at Peng Qidao: "How much money I received from the Cao family, to be honest, I will not blame you, and I will not confiscate your things, what I want is the truth." ”

Peng Qi was horrified in his heart, and suddenly knelt down: "The last general deserves death, and he shouldn't test the official family for him Cao Wei, the last general accepted the Cao family...... No, it should be a mansion and a Zhuangzi that sent the door...... The house is near Kangping Gate, and Zhuangzi is outside Nanxun Gate! Still...... And two beautiful ......."

Zhao Zhen smiled slightly: "These things are much more valuable than gold and silver treasures!" Kangpingmen's mansion can't be won without 100,000 yuan, and the Zhuangzi outside Nanxun Gate is the land that wealthy businessmen are staring at. The people who will be the gate are really willing to spend their blood......"

Peng Qi's expression was like a little daughter-in-law who had been caught raping, kneeling on the ground with remorse and shame on her face, of course, there was a lot of fear, after all, the person he offended was the emperor of the Great Song Dynasty, and Zhao Zhen's temper was considered to have been penetrated by him, otherwise he would not have said it so obviously.

kicked him Zhao Zhen and scolded: "Get up, you are not short of this money, why do you want to be a gunman for the Cao family and Jiangmen?" You are just a little greedy, which is far worse than Cai Boyu. ”

Peng Qihan got up with a smile: "The last general just can't stand this temptation, but how can they sit on their evidence without these things, since they yearn to drill in the sleeve, then the last general is not welcome...... Hey hey ......"

"That's it! You don't have to return things to them, but you bring my words to them, this is the top priority of the Northern Expedition, just know your mistakes, I don't blame the past, my attitude towards Jiangmen is still the same as at the beginning, meritorious service will be rewarded, and guilt will be punished! ”

Through Peng Qi's description, Zhao Zhen has understood the trick, Cao Wei and Jiangmen originally planned to attack Di Qing, but then they were persuaded by someone, and then they used Peng Qi as a bait to let him test his attitude, after all, at the juncture of the Northern Expedition, Zhao Zhen would naturally let them go when they did not cause evil results.

Looking at Peng Qi who was leaving happily, Zhao Zhen smiled slightly bitterly, people's hearts are sometimes so uncalm, and they have to fight for the sake of interests no matter what, yes, man is a greedy animal, without the greed in his heart, human beings may not progress.
