After hiding from the first day of the new year, Zhang Yi was finally brought back to Chang'an by listening to the wind, and the people of Zhangjiazhuang such as Yue 11, Lao Zhong, and Wang Wu also followed Zhang Yi back to Chang'an.

Shuo Fang's distance from Chang'an is not close, and Zhang Yi can have a lot of time to think about how to deal with Li Er on the way.

It stands to reason that his current credit is already great enough, and the gunpowder bomb invented during the war with the Turks can be regarded as a great achievement, and it is also a great achievement to properly dispose of those Turkic prisoners with the labor reform system after winning the war.

In addition, now that he has brought out the prototype of the tunpu system, it only takes a little time to get the tunpu system out, which is a great contribution to the benefit of the country and the people.

Thinking about it, Zhang Yi gradually felt that something was wrong.

Li Erhuo hurriedly asked Tingfeng to recall himself back to Chang'an, maybe it wasn't for his own?

From beginning to end, Tingfeng didn't mention Yang Su, and he didn't pay attention to the servants he brought, as long as Zhang Yi returned to Chang'an, it was enough.

Thinking of the Taiping technique, Zhang Yi quickly sorted things out.

At the end of the war, he didn't dare to meet Chang'an because he had done a little bad thing, and hid in Shuofang City to use those Turkic captives to build a fortress.

Looking back, Yang Su was already dressed in disguise, following behind Wang Wu and the others, and he would follow him as someone from Zhangjiazhuang.

However, Zhang Yi also knew that this matter would not be hidden for a long time, unless he didn't let Yang Su enter his door, or to put it mildly, unless he abandoned Yang Su, otherwise, Li Er would still know.

Instead of letting Li Er get angry and cut himself at that time, Zhang Yi felt that it was better to take advantage of the fact that he had so much credit at this time to say it together, so that he could still protect himself.

Moreover, Yang Su can also be a shield at this time, so that Li Er knows that he does not dare to return to Chang'an because of his bad affair with Yang Su, instead of deliberately staying in Shuofang City because he has other ideas.

As long as Li Er's doubts are dispelled, then Zhang Yi's head will at least be saved.

As long as Zhang Yi does not threaten Li Er's country, then even if Zhang Yi makes a little mistake, he will not lose his head, not to mention that he has so much credit now.

With the bottom in his heart, Zhang Yi is not so panicked, as long as his life is saved, everything is a trivial matter.

A few days later, Zhang Yi and Tingfeng and others arrived at the foot of Chang'an City.

"You go back first, go back and report to grandma that you are safe, and you will go to the palace with me to see Your Majesty on the eleventh day of the month." Zhang Yi explained, and asked Lao Zhong to take everyone back to Zhangjiazhuang first, and then followed the wind to prepare to enter the palace.

Seeing Lao Zhong take everyone to Jingyang County, Zhang Yi sighed lightly and prepared to follow the wind to the palace.

I have to enjoy the feeling of fighting wits and courage with Li Er again, to be precise, only fighting wits and mouths.

"Uncle, Princess Chengyi is already pregnant with your flesh and blood." Everyone was walking, and Yue Shiyi said this sentence to Zhang Yi coldly.

Zhang Yi froze in place.

What is the special winning rate so high, you can plant the seeds overnight?

Thinking that Li Hui also had a big belly at this time, he was going to go back with a big belly soon, and Zhangjiazhuang was going to make a fuss!

However, it is still easy to solve on the Zhangjiazhuang side, and when it is difficult to get it, Li Er's side, Yang Su is the princess of the previous dynasty, and now she is pregnant with his blood and bones, what will Li Er's side think.

Coincidentally, Tingfeng just heard this sentence from Yue 11, although Yue 11's voice was very low, but Tingfeng was next to Zhang Yi, Zhang Yi heard it, and Tingfeng naturally heard it.

However, he didn't plan to pay attention to these things, just glanced at Zhang Yi, and continued to walk towards the palace.

These things are not in his own hands, he only needs to bring him to His Majesty, and then present the information he has collected to His Majesty, as for how to decide, it is Your Majesty's business.

The palace is very large, although there is Tingfeng brushing their faces in front, but they still walk for a long time, but even if they walk for a long time, they will all walk to His Majesty Li Er.

Just won the battle, and also got the news that Zhang Yi was successfully recalled, His Majesty Li Er seemed very happy at this time.

Although the eldest grandson already had a big belly, at this time, he still chose to stand behind Li Er and massage him.

At this time, Li Er will need him, after all, he is facing the demon Zhang Yi, and he needs to let her solve some things when necessary.

"Minister Zhang Yi, meet Your Majesty, meet Niangniang."

"On the eleventh day of the month, meet Your Majesty, meet your mother."

"Listen to the wind, meet Your Majesty, meet Niangniang."

......

After everyone knelt down to greet each other, Li Er began to face Zhang Yi squarely.

He had read all the news sent back by Hearing the Wind in advance, and he had no other suspicious behavior except for the tunbao system that Zhang Yi had told him before.

This is good news, as long as Zhang Yi doesn't have any other thoughts, then it will be easy for him to do it, at most the radish stick will be put on together, and he will be sure to clean him up properly.

"Zhang Yi, have you gained anything this time?" Li Er asked Zhang Yi slowly and leisurely, as if he was talking about family life.

But Zhang Yi knew that it was definitely not that simple, it seemed to be nonsense, but as long as he spoke, Li Er would soon be able to judge his thoughts, this is the art of the emperor.

However, Zhang Yi has no ghosts in his heart, so he naturally will not be afraid of these, and he will answer Li Er's questions fluently.

After some talking, Li Er could basically be sure that Zhang Yi was safe.

"I heard that this time you also made a gunpowder bomb in Shuofang City, listen to the wind and show it to me, it is indeed a very good thing!"

Li Er smiled and gestured, and began to change direction.

Obviously, as a military strategist, he is very clear about the role of gunpowder bullets in war, if used properly, it can completely equip the army on a large scale, once the Tang army is fully equipped with gunpowder bullets, the combat effectiveness will be greatly improved, and when the time comes, it will truly become an invincible army of victories.

When Zhang Yi heard Li Er talk about gunpowder bombs, he also instantly became interested.

He knows too well the role of equipping gunpowder into the army, if gunpowder shells can be equipped to the army on a large scale, it will definitely be a milestone, and the gap between hot weapons and cold weapons can be known from the modern history of China.
