Overnight, it seemed as if it was the end of the world, Xianyang City became deserted, and all the officials and gentry disappeared without a trace, as if they had never appeared before.

Li Chengqian stood outside the courtyard, looking at Xianling who had become desolate after returning to normal, and said sorry to the old man in his heart, turned around and looked at Tang Shanshi who had just returned from Goguryeo: "How is it? Is it okay in Goguryeo?"

"Gaoming, there is no Goguryeo now. In addition to the pseudo-Chang'an, it can also prove that there was a country on that peninsula. It has completely become a path of our Tang Dynasty. Goguryeo can only be found in history books in the future."

Tang Shanshi laughed strangely and joked. He had just returned from the front line. Since the Liaodong Legion won a decisive battle with more than 200,000 reinforcements from Goguryeo, he has been advancing all the way. He, a logistics officer, had to move his official office forward, and finally moved directly to Li Daozong's central army tent before he could calm down.

So none of the people present knew better about the situation in Goguryeo than him, even if he had left the front line for a month.

"Why haven't an attack on the pseudo-Chang'an? If I'm not wrong, Silla and Baekje should have been too busy to retreat to the local area, right?" Li Chengqian got a lot of news about the Liaodong Legion from one-sided information. He could generally grasp some legion trends, but he did not understand the specific situation.

After all, the highest commander of the Liaodong Legion is Li Daozong. Without wanting to expose Cui Yu, Li Chengqian could not understand how the overall situation of the Goguryeo battlefield was arranged.

Another point is the issue of command. Li Chengqian is just a prince, not an emperor. Faced with Li Daozong who was authorized by the old man, he could not show excessive concern for the Liaodong Legion, otherwise it would only make things more and more troublesome.

When Tang Shanshi faced Li Chengqian's problem, he spread his hands helplessly and said, "Isn't it that new Goguryeo emperor? That boy threatened us that if he dared to attack the city, he would burn the palace with a fire."

"Burning?" Li Chengqian turned his head in surprise. This was the first time in the Tang Dynasty that he had heard of using himself to threaten others. He couldn't help but feel curious.

"Yes, that guy actually threatened us with his own life." Tang Shanshi also found this incident a bit incredible, but he quickly continued: "But we don't care about his bad life. There are many good things in the pseudo-Chang'an, so these things cannot be burned, right? So the siege was delayed."

"Tsk, who arranged this matter? What is there in the broken palace of Goguryeo that we don't have?" Li Chengqian didn't know how to express his emotions. He didn't know who would care about whether some precious cultural relics from the enemy country would be destroyed besides the iron army in later generations.

As a result, Tang Shanshi shook his head and pushed him out: "I don't know who arranged it. I can tell why I don't attack because I'm like to inquire."

Facing Tang Shanshi who was unaware of his questions, Li Chengqian chose to give up, tapped on the table and said, "Forget it, since you are back, don't worry about Goguryeo. Keep going back and help me with that steam engine. Before you create a steam engine with multiple cylinders, don't think about coming out of the research department."

"What? It's a steam engine again? Isn't Changsun Chong doing that thing? Why is it me again?" Tang Shanshi thought there would be some important arrangements for transferring him from Liaodong, but he didn't expect to do the 'old business' again.

"I can't believe it except you, you can admit it!" Li Chengqian waved his hand.

That boy Changsun Chong was not a down-to-earth person at all. Letting him build a steam engine was the biggest mistake Li Chengqian made. So now His Royal Highness decided to make trouble, appoint talents again, and transfer Tang Shanshi back to do this thing again.

"No, Gao Ming, you can't cheat me like this. Look at the other brothers, which one is not a fifth-grade rank. It's too embarrassing to be the only one below the sixth-grade rank, right?" With the idea that since you can't resist, you have to put on a comfortable position, Xiao Tang tried hard to win all rights for himself.

"This problem no longer exists now. The Research Office is already a fifth-rank department. After taking this job, you can immediately go to the Ministry of Personnel to inquire and see if I have lie to you." Li Chengqian seemed to have made a premeditation, knocking down all Xiao Tang's reasons in one sentence.

Moreover, Li Chengqian really did not fool Tang Shanshi in this regard. The Research Office had already been upgraded by the old man after his application a month ago. The level above the fifth grade can be comparable to that of the general supervisor.

Li Shimin also saw the potential of the Research Office during this period. With the idea of ​​letting this department continue to work hard and making more money for the Tang Dynasty treasury, Li Chengqian did not use much effort to do so, so he agreed to his request with the flow.

This made Li Chengqian very regretful. If he had known that the old man could agree so easily, he might as well mention the fourth grade in one step.

However, it is a bit too late to say anything now. The Research Office, which has just been promoted, cannot be further raised no matter what. Even if it is really possible, it will be difficult for Tang Shanshi to take over the position of the agency order at that time, so Li Chengqian gave up this idea.

"Gao Ming, can't you really change it?" Tang Shan asked again with one-tenth of hope.

"I told you a long time ago, you must be. If you don't talk nonsense, do you believe me or not, I'll go to your father?" Li Chengqian was a little annoyed by the grinding, and threatened with a glaring eyeball.

"Okay, I'll go, can't I go?" Xiao Tang immediately became timid when he heard his father: "But Gao Ming, you have to tell me what a multi-cylinder steam engine is, right? I've been running outside for more than a year, and I've forgotten all the things I made before."

"If you have any questions, please go back to the Research Office and ask yourself. I will only tell you that one is a multi-cylinder steam engine and the other is a miniaturization of steam engines. These two must be done quickly. Especially the problem of miniaturization, if it can be reduced to one-fifth, I will ask you for me and be named a marquis."

In theory, as Li Chengqian's current status as the crown prince, he should never agree to be granted a title of marquis and ministers, so it can be seen that Li Chengqian also fought hard for the sake of the steam engine.
