The army of Liao was still unhurriedly carrying out civil work outside the city of Liaodong, and when a small flood in Liangshui passed, Hou Junji found Zhang Gongjin, and after some discussion, there was Wang Xiaotong accompanying the front army.

"Wang Taishi, I'm tired."

"The manager is serious."

The old man arched his hand, and then spread out the drawings, and the engineering team continued to wind through the ditch until it reached several gates in the west of Liaodong City.

In order to prevent the Tang army from landing in the city, the head of the city was densely covered with sandbags, and the partitions echoed left and right. If the Tang army attacked, it would only be a chaotic battle in the end, and it would be more than who would fight.

Liaodong City is one of the capitals of Goguryeo, and the population in the city itself is quite large, coupled with the strong walls and clear fields, many people in Liaodong have been forcibly moved into the city.

"Watch the shield cart slow down!"

Old man Wang commanded, the people of Poly Construction are all familiar with the way, and the guy brought this time has a simple equipment similar to a shield machine. The ceiling is made of stainless steel and supported by a frame of cast iron. It was originally used for the operation of the soil coking tunnel, and later it was also used in the drainage system of the Shicheng Iron and Steel Plant.

"Watch the track!"

If the tunnel work needs to be heavy, the interior space can be used to load iron structures and workpieces. For example, scaffolding or reinforced iron pipes, etc., at the same time, after the operation, the earthwork in the tunnel can also be directly transported.

In the Shicheng Iron and Steel Plant, during the trial production of the first Bethelman-type blast furnace, in order to facilitate feeding, long-distance rails were directly poured on the flat ground. The gauge is just enough to accommodate two Hexi horses in parallel, and in order to increase the volume of materials from the steel plant to the work area, the new body has hinged joints.

Similarly, when the shield car was operating in the mining area, Wang Xiaotong and Zhang De carried out extreme tests on the firmness of the shield car in order to ensure the output and production progress. According to Zhang De's estimate, it can probably be more than six tons, but the Shicheng supervisor sent by the imperial court recorded a hundred stones.

"Wang Taishi, you have arrived at the city gate."

"Hmm."

Wang Xiaotong picked up the binoculars, looked at the small red flag erected behind the shield car from a distance, and then said, "Charge." ”

With an order, soon under the gate of Liaodong City, the track tools of the earthwork industry were withdrawn one after another, and a large number of special items were piled up inside the shield car one after another.

"Withdraw!"

When the green flags were erected outside the tunnel, Wang Xiaotong put away the binoculars, and then said, "How much is the charge?" ”

"The secondary gate is 2,000 catties, and the middle gate is 5,000 catties."

"Hmm."

The old man nodded, "Ignition." ”

With that, he turned around and went to the big tent of the Chinese army.

"Ignition!"

"Ignition!"

"Ignition—"

A rapid whistle sounded, which was used by the Shicheng Iron Works and many mines to supervise slave laborers. When the whistle sounds, it is to start work. When the whistle blows again, it is the end of work.

At this time, Wang Xiaotong's disciples were all wiping their sweat, and then they were talking about God's blessing, and there were also descendants from Chudi, and they were talking about the true greatness of Taiyi.

In the spring, the blessings are revived, bright and pleasant. It's a season that makes people happy.

Boom -

It's like a flash flood, as if the Yellow River is bursting, and it's like a thunderstorm, that loud noise, accompanied by a slight rise and fall on the ground, the city gate of Liaodong City collapsed instantly, no matter how many stones and sandbags you piled up in the city gate hole, after all, it is not as indestructible as the city wall.

Goguryeo followed the example of Middle-earth, and the walls of Liaodong City were also rammed earth walls. If it is to blow up the city wall, relying on black powder, the dosage is at least 100,000 catties. And the effect is probably that the integrity of the city wall is still as high as seven or eight percent, as for the bronze cannon iron cannon, bombarded on the rammed earth wall, at most smashed a few pieces of the outer wall rock wall, and then there was no then, listen to the sound.

If they want to open the gap, Wang Xiaotong and Zhang De have tried several times in Pingzhou, and the best way is to open the city gate. Basically, according to the Datang system, the scale and layout of the city gate of the state city require a charge of about 2,000 catties to be able to blow it up smoothly. As for the city walls, there is no need to think about it at all, this is what I said about hitting stones with pebbles.

Unless Lao Zhang makes a big explosion at this time, but this technology tree is lit, and Lao Zhang is almost already famous in history.

"Hongshen, a few people who came back to Jianghuai last time took the Tiaochen of the King of Hejian, making it difficult for Hongshen to do. However, this time, a certain guarantee that as long as Liaodong City is taken, the young and strong laborers will be ......."

Rumble!

The big tent of the Chinese army trembled suddenly, and Hou Junji, who was holding the teacup, was startled, and almost lost his temper to the point that the teacup fell to the ground.

His face changed, and he said in surprise: "Thunderbolt on a sunny day, what ...... is this?"

"Boss! The gate of Liaodong City has been broken! ”

Hou Junji was stunned.

Chang'an, and then to the Great Dynasty Meeting, the generals of the Twelve Guards are talking nonsense there.

"Phew! What kind of battle did the Fenzhou Yan fight, he cowered and stagnated, taking a small city is a good news, taking a small dirt bag is another good news, and the total good news in twenty or thirty years is not as much as he alone! ”

"That guy doesn't know what to play, I'm a guest army, I don't want to fight a battle, and I should be ......"

"Ahem!"

The people in the military all shut up, Li Jing walked to the front slowly, and there was another person in front of him, who was even slower than him, but his face was not very good-looking.

Li Xiaogong glanced back at Li Jing and smiled bitterly. Li Tianwang didn't speak, but raised his hands slightly, which was regarded as a salute.

After standing still, Cheng Yanjin, who returned to Beijing to report on his work, smiled, squinted his eyes and smacked his beard: "Pharmacist, do you have any advice on this expedition to Liao?" ”

"Don't dare to advise."

Li Jing has nothing to say to him, and he can't play together at all. If it weren't for Zhang Gongjin, probably Li Jing and Cheng Yanjin would not have had much intersection in this life.

"Zhang De and Li Desheng are familiar with each other, and when the prince was touring south, he went to the south to go boating and fishing. Now, hey, it's not what it used to be. ”

The corners of Li Jing's mouth twitched, and then he squinted at Cheng Zhijie, who was extremely happy: "Cheng Sanlang praises the protection of the capital of Anbei, and the future is immeasurable, Cheng Gong is gratifying." ”

Cheng Chubi's life is not easy, but it is true that the future is immeasurable, but in the future, he will not be able to take off the hat that Wei Chi carries every day. In short, Cheng Zhijie was very unhappy. The combination of day and day, compared with the house plot, the gold content is still a little worse. Coupled with the fact that Cheng Yanjin, who is a human spirit, thinks that he is a character like him, how can his descendants be reduced to the extent that he wants others to promote?

However, what I never expected was ...... The son actually went to mix rice under Wei Chigong's hands, and he mixed it well, and even the emperor praised it. Not only the emperor, but the Turkic mad dog also marched from time to time, not to say how loyal Cheng Saburo was, or how Cheng Saburo was patriotic.

In short, Cheng Sanlang, according to the old devil and the old mad dog, is a proper court's henchman and party-state cadre, a model for the sons and daughters of the nobles, and a role model for the second-generation elite.

But this is not what Cheng Yanjin wants, and now that his son is completely tied to Wei Chigong and even Ashina Simo, this is even more uncomfortable than going to Pingkangfang to find an old bustard to sleep.

"Huh."

Cheng Zhijie didn't speak for a long time, held back two words, and then blackened his face, not knowing what to think about. At this time, there was a commotion outside, and there was the sound of horses' hooves, and soon, the bigwigs got the news, and it was another good news from Liaodong.

"Good news! Do you have nothing to do except report victory?! ”

"Which village will you hit this time?"

"What do you say about this good news?"

It was another hustle and bustle, and after a while, Shi Dazhong, who had retired for several years but was rehired by the queen, wiped the sweat on his forehead and passed by the corridor.

"Shi Gong, how is the good news?"

Shi Dazhong faced the court officials, no matter how big or small, they were extremely humble, and he didn't look at who it was, and hurriedly saluted and replied: "Oh, it is said that Liaodong City has been defeated." A certain was about to go to the Yeting Palace to give instructions and prepare for the celebration banquet. ”

After speaking, Shi Dazhong lowered his head again and hurried towards the west wiping his sweat. (To be continued.) )
