Shi Chaoyi said hesitantly: "But if you lead soldiers to save them, you will always hurt people's lives, and I really can't bear to let the soldiers die on the battlefield." ”

Tian Chengsi muttered to himself, this turtle son is greedy for life and afraid of death, what kind of shield do you use the soldiers.

"Childe, why do you really have to do it to rescue Youzhou City, you can take an elite force under your command to go to Youzhou City at night, and break into Youzhou City without the enemy noticing, just shout a few times under the city, and let your father know that you are here to rescue Youzhou. But don't stay in the city too long, because it won't look good if your father does open the gates and rush out. ”

"Do you want me to go in person?" Shi Chaoyi's eyes widened.

"Naturally, you have to go there in person, otherwise how can you reflect your loyalty and filial piety."

He turned around in place four or five times, as if weighing the pros and cons, and finally slapped his thigh and made up his mind: "I have broken through this ghost gate." ”

Tian Chengsi and Shi Chaoyi first led the army to Lulong County in front of Yuguan, and quickly set up camp, and then it was Shi Chaoyi's turn to be the protagonist. Tian Chengsi personally cheered him on and watched him leave far away.

Shi Chaoyi took his elite prince and selected more than 1,000 trustworthy brothers, and decided to pass through the middle of the junction of the two Li Siye's military camps in the north of Youzhou City, and then rushed to the north gate to perform. Presumably, with the elite level of the Hexi army, it will soon be killed from his back, so that he can be forced to retreat calmly.

The moon was sparse, and Shi Chaoyi led the army to gallop through the junction of the Hexi military camp with hidden torches, and although they were cautious, the sound of horses' hooves alarmed the Hexi army. Immediately, two cavalry teams rushed to the city of Youzhou after their buttocks, Shi Chaoyi immediately ordered the soldiers to shout and kill, and ordered people to shout towards the city: "Gongzi Shi Chaoyi specially led the army to rescue Youzhou!" ”

It just so happened that Shi Siming has set an example these days, eating and sleeping on the city tower, and after hearing the shouts in the distance, he immediately put on his clothes and stayed, and there were soldiers kneeling on the ground outside the door and reporting with their hands crossed: "Your Majesty, Gongzi led the army to save Youzhou, and at this moment he is fighting with the enemy army under the city." ”

"Who called him over! Let's go, follow me to the city walls! ”

Shi Siming looked down from the top of the city, and he couldn't tell who was who in the darkness, only saw thousands of torches shaking under the city, and the shouts of killing were fierce.

Shi Siming smiled contemptuously: "What can you do at night?" It is only possible to rush under the city wall during the day. ”

A general asked in a low voice behind him, "Do you want to open the city gate and send someone out to pick him in?" ”

Shi Siming scolded angrily: "Confused things! I can't tell who is who at night, in case it is Li Siye's army that is brought in by opening the city gate, you and I won't let the family serve a pot! ”

He heaved again and said: "If he really has the heart to save Youzhou, he should choose to attack the other party's camp at night, instead of rushing straight to the city gate, didn't Tian Chengsi teach him this?" Who will show the sword and gun in front of the city gate? ”

He stood on the city wall with his hands behind his back and looked at it for a while, before turning back to the castle tower and lying down in his clothes, he could faintly hear the shouts of killing in the distance, which sounded a little contrived. As time passed, the voices faded away, and he snorted contemptuously.

Shi Siming suddenly realized that something was wrong, and suddenly sat up from the bed, holding his knees with both hands and roaring angrily: "This beast! He lost Jizhou! ”

……

Shi Chaoyi rushed and killed for a while under the city wall, and then hurriedly led the troops to retreat to Yuguan, Tian Chengsi was looking forward to it outside the camp in Lulong County, and saw Shi Chaoyi running over with the big team, and hurriedly stepped forward.

Shi Gongzi jumped off the horse with a flushed face, looking very excited, he estimated that his battle was a game of pro-novelty and excitement.

"How's Childe doing?"

"I've been killing dozens of rounds under the city, and I dare to guarantee that he must have heard it on the city tower, and even if he can't hear it, his soldiers will report it."

Tian Chengsi crossed his hands and asked him: "I don't know if Your Majesty has opened the city gate for Gongzi." ”

"No, you can't tell who is who in the middle of the night, the enemy and our army are rushing together, who dares to open the city gate for you. I told the soldiers to shout a few more times under the city before I took them away. ”

"Really?" Tian Chengsi laughed embarrassedly a few times, and said to Shi Chaoyi: "In this case, Gongzi, please enter the customs with me and the army." ”

They led the Yan army to the city wall and shouted to the city wall: "Quickly open the city gate and let us in." ”

The guard lay down on the city wall and asked in a loud voice, "Who is the one who came down from the city?" No one is allowed to enter the city without a warrant from His Majesty! ”

"Open your dog's eyes and see, I'm Shi Chaoyi! The rescue of Youzhou failed, and for the time being, he took refuge behind Yuguan, and he didn't open the city quickly. ”

"It turned out to be Gongye, hurry, open the city gate quickly."

Shi Chaoyi finally figured out why Tian Chengsi didn't enter the city by himself, it turned out that he couldn't enter without himself, the prince, thinking that he still had such authority, his heart was much more comfortable.

As soon as the 40,000 troops entered Yuguan, it was equivalent to running to the boundary of Liaodong, and the foundation of the Pinglu Jiedu envoy was in Yingzhou City after this Yuguan. Even if Youzhou City is defeated, Shi Siming still has half of the foundation for him to make a comeback in the eastern Liaodong region.

In order to continue to provide war resources, he ordered people to relocate the Taoist workshop that produced gunpowder to Jizhou City, recruit blacksmiths and apprentices in the city, and produce artillery shells to supply the siege of the city.

Xu Bin personally participated in refining the shape of the large Kong Ming lantern, which by now no longer resembles the Kong Ming lantern, with a spindle-shaped structure made of cowhide and bamboo and wood. Six leak-proof copper oil lamps with windshields side by side, which can control the size of the flame to control the height, the tail has a bamboo dragonfly with a large thrust, and the transmission mode is no longer a hand pull but a pedal, a bit similar to a waterwheel, and there are bamboo dragonflies on the left and right sides that control the horizontal direction, which can resist the wind within the fourth level, and the direction cannot be controlled if it exceeds the fourth level.

There are four people in the gondola, three of whom control the flight direction of the Kong Ming lantern, and one person serves as the lamp chief and bombardier.

If the Xuanwu cannon caused psychological damage to the soldiers in the city, then the giant Kong Ming lantern was a real blow, these things were suspended in the sky above Youzhou City every day, bombing the living facilities and grain and grass in the city, and the grease dropped by the fierce fire and thunder made the soldiers who fought the fire tired.

These thunders made the Yan soldiers unguardable, and they had to hide in the brick caves on the city wall, and they would be bombed if they showed their heads. Especially when attacking the city, they not only had to resist the attack of the Hexi army climbing the city wall like a tide, but also had to guard against the fierce fire and thunder attack overhead.

The casualties of the Yan army were becoming more and more serious, and Shi Siming went to patrol the city wall every day, and was shocked to see such a situation, so he had the idea of retreating to Liaodong. It's just that he can't put forward this idea himself, because it doesn't match his personality.

His opponent Li Siye also became more and more terrifying at this time, and he was not arrogant or impatient and attacked the city step by step. The daily artillery bombardment and Kong Ming lantern bombardment are also very regular, perhaps in his eyes, Youzhou City will be in his pocket sooner or later.
