Xiao Yu's eyes were green, it was obvious that he had not slept well last night, and Li Shimin felt a little uneasy, fearing that Xiao Yu would not be able to say anything that would not affect Chang'an.

However, although Xiao Yu looks bad, he is full of energy.

He smiled and said: "I have decided to leave for Chang'an with your aunt in three days.

"I'll leave Hechi's soldiers to you."

Li Shimin was overjoyed and immediately expressed his intention to send someone to escort them to Chang'an.

Xiao Yu did not refuse and agreed immediately.

In the afternoon of that day, Li Shimin rushed to Fufeng with his own army and soldiers from Hechi.

Xue Rengao heard that Li Shimin was going to attack Fufeng and led his army out of the city. Thirty miles outside the city, the two armies met and started a fierce battle.

After one day and one night, Xue Rengao lost 10,000 soldiers and returned to Longyou with only a few hundred remaining cavalry. Li Shimin led his army to pursue them all the way to Longshan before giving up.

When his son returned in defeat, Xue Ju was frightened and led all his subordinates back to the capital, Qinzhou.

After returning to the capital, Xue Ju was still in a panic. He was always worried that Li Shimin would attack him, so he asked the courtiers: "Has there ever been an emperor who surrendered?"

Chu Liang, the minister of Huangmen, answered this question subconsciously: "In the past, Zhao Tuo and the south of Guangdong returned to the Han Dynasty. Emperor Huai of the Shu Han Dynasty, Liu Chan, also served as an official in the Jin Dynasty. Xiao Cong, the last emperor of the Western Liang Dynasty, was recruited by Emperor Wen of the Sui Dynasty. His family is still there today.

.

"The emperor's surrender is just a matter of assessing the situation and there is nothing wrong with it."

As soon as these words came out, Xue Ju felt a little relieved, but he was immediately refuted by someone.

This person was Wei Weiqing Hao Yuan, and he said: "This is wrong. In the past, the emperor of the Han Dynasty was defeated many times, and the ancestors of the Shu Han Dynasty also lost their wives and children, but they all inherited the emperor's legacy.

"Winning or losing is a normal matter for military strategists. How can we decide on a strategy of subjugating the country just because of a defeat in one battle?"

Chu Liang's face was slightly hot, he chatted and then retreated.

Xue Ju suddenly realized that he was speechless, laughed dryly, and said: "It's just a test, don't take it seriously.

"Wei Weiqing is loyal, honest and forthright. I will reward you. I will reward you heavily."

Hao Yuan took the opportunity and said: "Thank you for your kindness, Your Majesty. I have a plan that will definitely help Your Majesty capture Chang'an."

"What good idea does Wei Weiqing have?" Xue Ju's eyes were blazing, his desire and urgency evident in his words.

Hao Yuan raised the corners of his lips slightly and said unhurriedly: "We can form an alliance with Emperor Liang and Liang Shidu, and then bribe the Turks with heavy gifts. If the three parties join forces and send troops to Chang'an together, we will definitely be able to capture the capital in one fell swoop."

Xue Ju heard this and praised it: "It's a good plan. I'll just follow what you said."

After he came to the court, Xue Ju immediately sent envoys to Turks and Liang.

----------

Chang'an.

Li Yuan was very happy when he saw Qu Tutong being escorted to Chang'an.

What made him even more unexpected was that the fortified Hedong City was captured in such a short period of time.

After listening to the messenger's report and reading Li Jing's memorial, he finally understood what was going on and couldn't help but sigh again, Wang Yu was really his lucky star.

"wrong."

Li Yuan regained consciousness, the smile on his face disappeared, and he looked at the messenger: "Why didn't Xiao Yu'er come back with you?"

The messenger was confused and innocent: "Didn't you send Mrs. Wang on a secret mission?"

"Secret mission? When will I assign her a secret mission..."

The words stopped abruptly, and the envoy immediately understood that he had been tricked by Wang Yu.

Seeing Li Yuan's face that flickered between bright and dark, the envoy immediately knelt down and said, "This subordinate deserves to die..."

"Xiao Yu'er, do you have anything for me?" Li Yuan interrupted.

The envoy quickly replied: "Yes, she sent someone back to Beijing and is waiting outside the palace at the moment."

"Tell him to come in."

Yang Mao lowered his head and walked all the way to the envoy. He held the wooden box with both hands and said, "I have met the King of Tang Dynasty. This is what Xiao Yu'er ordered me to give to you."

Immediately, a chamberlain came forward, took the wooden box from his hand, and handed it to Li Yuan.

Li Yuan couldn't wait to open the wooden box, and the first thing that jumped into his eyes were four words with flying dragons and phoenixes: Aye personally opened it.

This is a letter.

"Aye, forgive me for not listening to you and returning to Chang'an, but after you understand the matter clearly, you will definitely support my decision.

"That day, I was in the military camp...the cause and effect were like this. The talent of one person can equal the strength of thousands of troops.

"Please believe me, Aye. This person will definitely help Aye unify the world faster and create an empire that is unparalleled in the world... Maybe I can't come back to spend the New Year with you, but I will often send letters home...

..."

The messenger quietly raised his head and saw that Li Yuan's face was ashen after reading the letter, and his heart was beating faster.

Li Yuan put the letter back into the envelope, picked up the painting book in the box, and read it page by page.

The drawing book is full of cartoons drawn by Wang Yu. The content starts from Wang Yu's departure from Chang'an, including what he saw along the way, meeting up with Li Shimin, arriving at Tongguan and Hedong, and everything that happened in Hedong.

Li Yuan read it with no expression on his face. When he saw that there was something else in the box, he took it out and looked at it, and his eyes suddenly widened.

This is... the bed crossbow that Xiao Yuer mentioned in the letter just now that is more advanced than them?

It does look much smaller. Xiao Yu'er said that it only takes ten people to start it, but he doesn't know what's different about the internal structure.

Li Yuan looked at it for a long time and couldn't figure it out, so he should leave it to craftsmen who are skilled in this art to study.

Turning over the next piece of paper, Li Yuan's eyes widened. That time he asked Wang Yu if there was any way to improve the Zhuge Liannu. Unexpectedly, she developed it this time.

However, I was still inspired by that unknown person.

Hearing that there was a "flying fish bomb" that could kill people, Li Yuan imagined what this weapon would look like, but he couldn't think of what it should look like.

This stinky girl goes to rob someone without knowing their name, appearance, or age. She doesn't know whether to call her confident or ignorant and fearless.

What's even more annoying is that she actually pretended to pass on the imperial edict, oh no, she killed him first and then reported it, and she also asked Li Jing for troops?

Li Yuan picked up the teacup, took a sip of tea, and calmed down his shock.

However...if this person is really as powerful as Xiao Yu'er said, he is worth grabbing.

So He Chou... Now that I got it, don't waste it, let this person continue to study the glass.

The envoy observed Li Yuan's face from time to time and saw that his face changed rapidly in a short period of time. He couldn't help but wonder: What did Miss Wang write that made the King of Tang so unstable?

"You go down."

The envoy was stunned for a moment, and when he saw Yang Mao bowing and bowing out, he quickly said: "My subordinates are leaving."

"You stay." Li Yuan pointed at Yang Mao and said.

The envoy took one look and hurriedly exited the hall.

When he arrived outside the main hall, he patted his chest with lingering fear. It was so dangerous. Fortunately, King Tang did not punish him.

After a pause, Miss Wang coaxed him back to Chang'an in the name of King Tang, but King Tang was not angry?

It seems that Miss Wang has a very high status in the heart of the Tang Dynasty...

In the main hall, Li Yuan asked Yang Mao about what happened along the way, and Yang Mao told Li Yuan everything in detail.

The words spoken are basically consistent with what Wang Yu wrote and painted.

Li Yuan felt relieved. After a moment of silence, he said to Yang Mao: "I will allocate five hundred people to you. You can take these people to chase Xiao Yu'er. She may have entered the territory of King Changle at this moment.

"Remember, go in disguise and don't alert all parties.
