After Lu You knew about this situation, he ordered someone to carry out two trebuchets and threw more than a dozen gunpowder bullets at the cavalry camp and the shield camp over there, and the two camps on the other side quickly became chaotic again, and even the soldiers with these trenches were also trampled on a lot, and the Khitans saw that the situation was not right, and ran back to the city.

However, the next morning, the Khitans organized a cavalry team of several thousand people, came out of another city gate, and went straight to the base camp on the side of Da Zhou.

It's just that this time Lu You really buried a lot of gunpowder on the way out of them, so Da Zhou won this battle again.

In this way, Lu You led people to fight more than a dozen rounds like a tug-of-war with the Khitan, and every time there were soldiers injured on the Khitan side, sometimes hundreds or even thousands, and when there was no wind, dozens of Kong Ming lanterns floated from time to time, making them feel like they were facing a great enemy.

A month later, when the Khitan saw that the ditch on the side of the Great Zhou had surrounded the three gates of Zhending, and only the last north gate was left, the Khitan generals fled with his few remaining soldiers.

It was really back in the hands of Da Zhou.

Lu You just took people to the gate of Zhending, and his subordinates sent Yan Yan's handwriting, and he also knew that Yan Yan gave birth to a son for him, named Lu Chu, Lu You wrote a letter back to Yan Yan, and sent his son a word, Dingbao, Dingding, Baozhou is Baozhou's Baozhou, because Baozhou is his next goal, I hope that the arrival of this child can bring him some good luck.

When Yan Yan received Lu You's reply, Li Cong in the palace also received the good news from the front first, knowing that Lu You had won two battles in a row, he finally let out a breath of turbidity.

However, he was very interested in Lu You's tactics and tactics, besieging but not attacking, attacking but not tightly, and not facing the opponent's challenge when he received it, but eating away at the opponent's strength little by little, and finally forcing the opponent to have no way out, so he had to abandon the city and flee.

The most important thing is that Lu You also knows to make full use of the nearby villagers, the men can help dig trenches, and the women can help make Kong Ming lanterns or go up the mountain to find pine oil branches to make arrowheads, which will directly become rockets after ignition.

I have to say that Lu You's small tactics and ideas are very effective, at least he held Jinju and took back Zhending.

It happened that Lu Chu's full moon ceremony was coming, so Li Cong, who was in a good mood, sent people to send a lot of congratulatory gifts to Mingyuan.

Yan Yan was also reading Lu You's handwriting when she received these congratulatory gifts, and looking at it, she suddenly had a question, whether that Zhou Lu was her traveling companion.

If so, why didn't he help the Khitan or Western Xia make gunpowder, as a modern person, even if he didn't study engineering in college, he should have been exposed to high school chemistry, right? The raw material of firecrackers is saltpeter, you should always know, right?

But if he is not a traveling companion, how can he explain his reaction when he heard "A Laugh in the Sea"? How can he explain that he has to find Yan Yan to talk about cooperation?

Also, what about the priceless night pearl and the 500-year-old ginseng?

Didn't he hint at her for the sake of his peers, but really took a fancy to her talents?

Just when she was puzzled, Old Madam Meng led Lu Jin in.

Mrs. Meng moved here the day after Yan Yan gave birth to Lu Chu, because the palace learned the news of Yan Yan's birth at that time and sent congratulatory gifts, and Mrs. Meng also knew that Yan Yan did not move back to Lu's house to give birth.

For this reason, Mrs. Meng hurriedly took her two daughters-in-law into the door, seeing that Lu You was not around, and Yan Yan did not have a serious elder by her side, the old lady immediately stayed, saying that she wanted to accompany Yan Yan to finish the confinement.

Yan Yan was not easy to refuse, but fortunately, the old lady was transparent, and asked about Lu You's whereabouts and the process of the lawsuit, but persuaded Yan Yan to look away, saying that the emperor also has the emperor's difficulties, and the current war is so tight, the emperor will not be able to deal with them, the news has spread, Yan Peng and Lu Ming still have the heart to fight?

Who knew that Mrs. Meng had just settled in Mingyuan, and the Zhu family also came to the door with Mrs. Lu.

It turned out that Yan Yan did not move back to the Lu family to give birth, which had already aroused doubts from the outside world, and after Yan Yan gave birth, the Zhu family and the Ma family did not show up for the first time, and the outside world sensitively linked this matter with Yan Yan's previous lawsuit against Yanfu Diao Nu, so there were rumors outside that were unfavorable to Lu Ming and Yan Yu.

Zhu had no choice, in order to calm the rumors from the outside world, she had to pull Mrs. Lu to Mingyuan, originally she wanted to leave the old lady in Mingyuan, but Mrs. Meng had no intention of leaving, as if she was the elder of Mingyuan, and Mrs. Lu was not forced to stay, plus Mrs. Lu's body was not very good, because the mother-in-law and daughter-in-law left something and left.

And Mrs. Meng has been living with Yan Yan until now, in addition to taking care of Yan Yan's diet and sleeping with Lu Chu every day, most of the time is to play with Lu Jin, according to the old lady herself, Lu Jin is a little like Yan Yan's mother when she was young, so seeing this child, the old lady feels young again, like returning to when her daughter was young.

No, the old lady just brought Lu Jin in, and when she saw Yan Yan holding a stack of letterheads in her hand and pondering, she asked with concern if it was Lu You's letter.

"Back to my grandmother, my husband said that he helped the second uncle of the Lu family to defend Jinzhou, and recovered Zhending, the next target is Baozhou, grandmother, he's not bad, right?" Yan Yan replied with a smile.

In fact, she didn't expect Lu You's luck to be so good, and he made two great achievements as soon as he arrived at the front line, but it didn't seem to be fair to Lu You just to say that he was lucky, Yan Yan knew that he still had some strength, and he read a lot of military books, but he didn't understand it before, and he didn't have the opportunity to fight.

In addition, Yan Yan explained to him some classic war scenes and strategies and tactics that he had seen in his previous life, such as tunnel warfare, mine warfare and protracted warfare, etc., which were all suitable for dealing with the Khitan cavalry, and Lu You's comprehension ability was still very strong, no, it was quickly used.

Seeing Yan Yan praising her man with a smile on her face, Mrs. Meng couldn't help but step forward and rub her granddaughter's face, and said with a smile: "It's not serious, my granddaughter is also bitter." ”

The old lady is most satisfied with Lu You not because of his ability, but about his single-mindedness towards Yan Yan, who has been married for more than three years and doesn't even have a concubine by his side, which is really difficult to do.

If you say that he was a dumb person and a fool before, no one wanted to talk to him, but later he could talk, he also entered the academy, and was admitted to Xiucai, just like that, he still guarded Yan Yan alone, which shows his character.

When the two grandparents were getting tired of it, Qingmai said outside that someone from the Lu family was coming.
