The reason why Li Cong has complete trust in Yan Yan is because of Mrs. Yan, Yan Yan was brought up by the old lady, Mrs. Yan has responded to the royal family all these years, and he has seen that loyalty in his eyes and in his heart; Second, Yan Yan's father died in battle for him, and there is no need to doubt his loyalty; Third, Yan Yan has solved a lot of problems for him in the past two years, not only saved the crown prince, but also saved the emperor's eldest grandson, and this time he and the queen mother were saved.

And the most important point, Yan Yan is a female streamer, and women generally do not have any ambitions, and they are easy to be kind, which can be glimpsed from what Yan Yan has done in the past two years.

Because of this, Li Cong let Yan Yan do any research, because he knew that Yan Yan would tell him about his research results every time, and he was sharing his worries.

Therefore, in view of Yan Yan's contributions in recent years, Li Cong wanted to do something for her, and he knew that this child was wronged by marrying Lu You.

"Well, not for the time being, I'll talk about it when I think about it." Yan Yan pursed his lips and smiled after speaking, "But there is one point, my knowledge is limited after all, these things are also requested to be discussed by the emperor and the ministers of the court, one person is short and three people are long, we have so many capable people in Dazhou, this war will definitely be won." ”

She's looking for a way out for herself.

She was afraid that if history did not follow her in the previous life, and if the Mongols, Uighurs, Tibetans, Dali, and Jiaozhi also followed the Jurchens and Khitans in trouble, then it would be a big trouble.

Of course, the reason why she dared to persuade Li Cong like this was precisely because she saw that Li Cong was still a relatively close to the people and enlightened emperor, and he did not have the kind of ruthlessness that turned his hands into clouds and turned his hands into rain.

This should be related to the state system of the Great Zhou, for more than two years, Yan Yan found that the emperor of the Great Zhou did not have the absolute right to speak, and many decisions had to be collectively discussed by the three provinces and six ministries, and the prime minister also had a veto power, so the emperor of the Great Zhou sometimes had to look at the faces of the courtiers.

This is also the reason why Li Cong compromised with Lu Duan when Yan Yan was forced to quit his family, of course, it is undeniable that Li Cong really couldn't find a better solution at that time, unless Yan Yan could really live incognito without marrying for the rest of his life or changing places.

When Yan Yan was thinking about how to persuade the emperor to find some skilled craftsmen from the people, Da Jiang came back and brought two grenades, the size of a fist, with a two-inch-long lead, saying that it could blow up a hole in the ground and cripple a sheep, and no matter how big the animal was, they had never tried it.

When Li Cong heard this, he immediately called a few eunuchs to come, and on the one hand ordered someone to call the prince, and on the other hand, he ordered someone to go to the stove room to lead two sheep to the back garden.

Half an hour later, Yan Yan also followed them to the Imperial Garden, Li Cong was carried by several eunuchs wrapped tightly and practically in the dragon chariot, the dragon chariot was carried directly into the pavilion, Li Cong did not come down, and sat directly in the dragon chariot.

On the other side, the prince ordered the two sheep to be driven to the lawn by the lake, and Yan Yan measured it on foot, and the distance was roughly forty meters, which is usually said to be twelve zhang.

Li Ji threw the grenade first, but he didn't ignite it, he just wanted to try the distance, maybe because he knew martial arts and had a little internal force, he easily threw it more than forty meters away, while the average eunuch could only throw about twenty meters, this distance was obviously not enough, and it would hurt himself if he didn't do it.

The next explosion test was completed by a eunuch in his twenties, he shivered after the fuse was lit, he was frightened and threw the grenade out with his eyes closed, only thrown more than ten meters away, the grenade did not explode after landing, it was only sounded after a while, the explosion also scared the two sheep into scurrying, but did not hurt them at all, mainly because it was too far apart.

Li Cong was obviously not satisfied with this result, and just as Li Ji was about to play in person, a medium-sized, twenty-year-old eunuch volunteered to stand up, saying that he was naughty when he was young, and his favorite thing to do was to set off firecrackers.

So, Li Cong ordered someone to give him the last grenade, but he lived up to expectations, after the fuse was lit, he saw that the fuse was burned to more than half of it, so he calmly threw the grenade near a sheep, and with the sound of explosion, the sheep also lay on the ground, and the scene was a bit miserable.

Li Cong was quite satisfied with this result, and there was another point, this eunuch also threw a distance of more than ten zhang, which is also very rare.

Moreover, the eunuch also made a suggestion, saying that the lead was too long, and it was thrown too early, and before the grenade exploded, the other party could pick it up and throw it back, so that it would definitely hurt his own people.

Li Ji listened to the interrogation, and then learned that the eunuch's father had worked in a firecracker factory, and later died in a firecracker explosion accident, so the family collapsed, and he had to enter the palace as a eunuch at a young age.

Knowing that there was still an uncle and elder brother in his family who worked in the firecracker factory, Li Cong ordered him to go back to his home and bring all the best firecracker craftsmen in their village to the capital.

Yan Yan saw that these things had nothing to do with her, so she offered to leave, and Li Cong left her behind and ordered her to hurry up and make more grenades like this.

Yan Yan agreed.

Before, she just ordered people to study, and she didn't dare to produce it on a large scale without the emperor's order, but this time when she saw that the emperor spoke, she simply handed over the matter to the prince, because Yan Yan needed to raise a fetus in the next days.

In fact, after returning from the palace, Yan Yan lived a life of staying at home again, but would send Qingmiao and Qingyu to visit the queen mother in the palace every day.

It's not that she doesn't want to go in person, but Li Xi and Li Ran haven't left yet, and the Queen Mother is afraid that Yan Yan will be infected with some other illness to these two children, so she specially told her.

After a period of treatment, the Queen Mother's body is slowly recovering.

Not only her, but the emperor's body is also improving day by day, and the epidemic situation in the entire capital is basically under control.

Li Ji and the crown princess came to pick up Li Xi and Li Ran during the Dragon Boat Festival, at that time, Yan Yan also received an invitation from the Lu family and asked them to go back for the festival, saying that Yan Yu was also sure to be pregnant, this is one of them, and second, Lu Ming received a battle report from the front, the war between the Khitan and the Jurchens stopped, and the Khitan concentrated their forces on the border of the Great Zhou, this time they gave up Baozhou and directly took Yanmen Pass and Daizhou, and the situation became very unfavorable.

Coincidentally, a batch of grenades was produced in these days, and Li Cong ordered Lu Ming to take these grenades to recover Yanmen Pass, and at the same time sent him a few masters who made grenades.

In other words, after the Dragon Boat Festival, it is time for Lu Ming to return to the battlefield.
