Pyongyang was taken by Datang in a situation that no one had ever imagined, and even Li Shiji never thought that it would be so simple, and only one person died from beginning to end, and that was Yuangai Suwen.

In fact, long before the Tang Dynasty's troops arrived in Pyongyang City, the intelligence department transported the city-breaking mines into Pyongyang City.

The explosives sealed in the big iron bucket were unknown to the outside world, not to mention that there were Liu Zhao's people to help as an internal response, and it was not too simple to transport these things in.

And these things can be arranged in various places in the city, such as the inner and outer city gates exploding all the time.

Another example is the place where several water sources and rivers flow into and out of Pyongyang City.

The four gates of Pyongyang all have urn cities, and the original idea was to blow up the inside and outside together, so that the urn city would be nothing more than a ruin.

But in the end, these were useless, or the situation of Datang was too good, so good that even ordinary soldiers knew that they had no chance, and after the fight, they would definitely lose.

In history, those who were besieged and could still win because they had follow-up support, where did Goryeo go to find support now? No, except for Pyongyang, most of the world is the world of the Tang Dynasty.

So even ordinary soldiers know that there is no chance, so when Liu Zhao sent someone to announce the surrender, there was no one to lose, because surrender was Gao Jianwu's holy decree, so no one showed any loyalty at this time.

There was no problem with the Tang army entering the city, and Li Shiji did not send all the troops into the city, but only sent 20,000 Tang troops into Pyongyang City to maintain order, and then let the nearly 100,000 defenders of Pyongyang City go out of the city and live in the barracks outside the city.

These soldiers came from all over Goguryeo, and when the Tang Dynasty reorganized them and persuaded them to educate, they would be allowed to return to their respective hometowns according to their own choice. After all, their families are still there.

As the commander-in-chief of this attack on Goguryeo, Li Shiji naturally transmitted the latest news here back to Chang'an by radio.

When the news came back to Chang'an, Li Shimin was still excited, and immediately convened all the ministers to hold a court meeting, and then officially released the relevant news.

And at the court meeting, Li Shimin also directly announced that he would officially take the Yalu River as the boundary and appoint the peninsula as Silla Prefecture.

The former Goguryeo site north of the Yalu River was appointed as Liaoning Prefecture.

At the same time, Li Daozong was appointed as the temporary governor of Silla Prefecture, and Li Shiji was appointed as the temporary governor of Liaoning Prefecture, and ordered the two to lead the existing army of the Tang Dynasty to repair on the spot, appease the people of Goryeo, stabilize the society, assist the people of Goryeo in land reclamation, distribute fields in accordance with the policy of the Tang Dynasty, and migrate the people to the plain area, etc., waiting for the arrival of relevant personnel of the Ministry of Public Security of the Tang Dynasty.

After the appointment, this information will be transmitted directly to Liaodong.

"Father will leave tomorrow, my words count, you guard Chang'an City." Li Shimin said seriously.

"Father, you can go with confidence, do you need to let Liang Guogong and others accompany you?" Li Ke asked with a grin.

"No need, I'll take your mother, concubine and a few aunts out, by the way to see the mountains and rivers of Datang, I have asked the Ministry of Culture to help me choose a good day and auspicious day, just a month later, just on the first day of August in Datang in Mount Tai to seal Zen."

"Now that Goguryeo has taken it, the entire eastern part of the Tang Dynasty and other regions are in a state of ruin, and there must be a lot of things in the imperial court, and I went out more this time to relax. So just let Fang Xuanling, Wei Xuancheng, Changsun Fuji and others help you in Chang'an. ”

"Don't say that Dad didn't leave you behind, don't you want to work? If I take people away, won't you have to do some more work? Li Shimin looked at him and said angrily.

"Hehe, my father is wise." Li Ke laughed twice.

"Well, then that's it, you can arrange the boat and the like, and it will only take a few days to reach Mount Tai down the Yellow River, and you don't have to worry about safety." Li Shimin nodded.

"By the way, this time by the way, I will bring Jinyang and their little guys with me, otherwise if I am not there, they will not be able to rebel against the sky in the palace!" Li Shimin explained again.

"Okay, they've been clamoring to leave Chang'an City to have a look, and this is also an opportunity." Li Ke also nodded.

"Well, let's go, let's go, go ahead of you, a lot of time." Li Shimin nodded.

"Yes!"

"By the way, after you go out, by the way, ask someone to notify Qin Qiong to come over, I have to explain to him, this security problem in Chang'an City cannot be ignored." Li Shimin spoke again.

"Yes Dad, I know." Li Ke nodded, he naturally didn't think much about it.

Li Ke left, and soon Qin Qiong rushed to the Xuanzheng Palace.

"Shubao, I will leave Chang'an City tomorrow and go to Mount Tai, the time for Mount Tai to seal Zen is set for August 1, and I will explain your affairs, on the same day of August 1, the security departments of all places in Datang will hand over my secret holy decree to the highest officials in various places."

And asked him to gather local people, merchants, wealthy households, local security forces, garrisons, etc. in the city square where he was located! Do you understand? Li Shimin looked at Qin Qiong and said.

"Yes, I understand." Qin Qiong bowed down respectfully and saluted, as for what was inside that secret holy decree, Qin Qiong was not interested.

"Well, at that time, Chang'an City will also hold related activities in the square Temple of Heaven in the south of the city, and there will be people in Chang'an City at that time." Li Shimin said.

"Yes!"

"There's no room for anything to go wrong in this matter, understand?" Li Shimin said seriously.

"I understand."

"Alright, you go and notify the Ministry of Security as quickly as possible. There is still almost a month to go, which should be enough. Li Shimin nodded.

"Yes!"

Qin Qiong left quickly to arrange, a month's time, in terms of the current land area of Datang, it was really a little nervous, but fortunately, it was just a one-way notification of relevant news, so it was too late.

After explaining to Qin Qiong, Li Shimin naturally relaxed a lot here, everything was ready, as for the preparations for leaving Chang'an City tomorrow, Li Shimin didn't need to do it, naturally there were people under him to arrange.

In fact, when Li Shiji and the others reported the latest progress a few days ago, Li Shimin had already made arrangements for it, and he knew that victory was not far away.

As for following Li Shimin out, the eldest grandson and queen naturally have no opinions, they really don't have many opportunities to leave the palace, and they are naturally very interested in the current Datang, of course, they also want to go out.
