As the bookshelf opened silently, Li Ziyu walked out behind Cao Dahu and saw a study room of about fifty square meters.

The study room is like a small library, with rows of bookshelves filled with all kinds of ancient books, exuding a faint scent of paper and ink.

Near the south window, there is a large, delicate desk and a Taishi wood chair, and the red rosewood table and chairs add more color to the interior.

On that Taishi chair, an old man of about sixty years old was sitting at the moment.

This old man, or old man, has a square face, thick eyebrows and big eyes, and should have been a beautiful man when he was young. Even at this moment, although his hair has turned gray and his face has deep wrinkles, it has not damaged his own unique military temperament.

This old man is none other than Ren Guozhong, the old lady of the Ren family.

Although these days are often connected through the flying eagle, the details are not clear. Originally, there were people coming and going with each other on this road, but recently the personnel sent by both sides have not heard from each other and have never returned.

Although he knew that his eldest son Changqing was out of danger, the specific situation was not clear.

The letters exchanged through the Flying Eagle were all a few simple sentences, and they were all in coded language. In a recent communication, Hang'er didn't say anything about sending someone.

After being besieged from his home, he was afraid of exposing the flying eagles in his home, so he suspended all contact. It's been seven days, and I don't know what Changqing plans to do now, he is anxious.

Now I saw that Cao Dahu brought a little girl here, although I had some guesses in my heart. But I can't believe that Hang'er will send such a little girl here, after all, Yidu is already a rumor now.

At this time, Cao Dahu saw the old man. hurriedly stepped forward and bowed: "The slave has seen the old lady!" ”

The old man snorted, but his sharp gaze fell on Li Ziyu.

Cao Dahu hurriedly introduced: "Old lady, it was this little girl named Li Ziyu who brought the news of the old man."

"What? You mean evergreen," the old man subconsciously stood up from his chair and asked in shock.

Li Ziyu didn't need Cao Dahu's introduction, and she knew that the person in front of her was Ren Guozhong, the head of the Ren family. At that moment, he curtsied and bowed to the junior, and said respectfully: "The junior Li Ziyu has seen the old general. This time, I was commissioned by the general to come here, and I came by letter. ”

said. He took out a letter from his bosom and handed it over.

Cao Dahu hurriedly took the letter and respectfully handed it to Ren Guozhong.

Ren Guozhong read the letter carefully. I couldn't help but breathe a sigh of relief. He glanced at Cao Dahu, and Cao Dahu bowed down and retreated in understanding.

Only Ren Guozhong and Li Ziyu were left in the study, and Ren Guozhong didn't know how to speak for a while.

Li Ziyu stood calmly in the study, her head drooping slightly. Be prepared to be questioned.

"Your name is Li Ziyu? Is it from Shiyan Town? Thank you for walking despite the dangers. I heard that you and Hang'er are getting along well. Also smart, you made the grenade? Ren Guozhong asked bluntly, but his tone was very gentle.

Li Ziyu couldn't help but laugh when she heard this. Xindao, this old man is really direct. I'm afraid this is the main reason why Ren Changqing sent him here, but Li Ziyu can also understand it.

Now the entire Yi capital is immersed in a tense and murderous atmosphere, and the Ren family can't compete with the soldiers and horses of the imperial court even if they have a little power. Moreover, the main force of the Ren family is not in Yidu, and far water cannot quench the thirst of the near.

What made her wonder was. Even if you prepare gunpowder yourself, it will be impossible to make a grenade in a short time. Unless the Ren family also has an underneath weapons factory.

Therefore, at this moment, Li Ziyu nodded and replied, "You are right, the grenade is from me." ”

Ren Guozhong had a smile on his face, and looked at Li Ziyu a lot. Changqing talked about Hang'er and this little girl in the letter, and he originally thought that a mountain girl was not worthy of Hang'er. But if a grenade can be developed, such a girl must be very smart.

It's just that I don't know if she will hand over the formula of gunpowder to the Ren family without reservation, he hopes that this little girl will know more about current affairs and not force him to take extraordinary measures.

So, he asked kindly, "Miss Li, so you have the formula for the grenade in your hand?" I wonder if I can give the formula to the old man? ”

Li Ziyu pulled her lips slightly, shook her head and said, "I'm sorry, I can't hand you over." But I can configure it for you, and I'll give you the blueprints for the grenade. ”

"What are the requirements? Can you call the recipe? ”

"Old General Ren, I won't give this recipe to anyone, because it's our life talisman. Even if someone threatens me with my sibling's life, I won't take it out. Because as soon as I hand it over, what awaits us will be the death of our whole family. I believe that General Ren would not do that kind of thing to kill chickens and take eggs, otherwise I would not have traveled for seven days to deliver letters. ”

Ren Guozhong secretly felt Li Ziyu's intelligence and calmness, and appreciated her more in his heart. He pondered for a moment, feeling that now was not the time to take tough measures, nodded and said, "Okay, what do you need, tell Shopkeeper Cao, after he is ready, you can just configure it in the Drunken Immortal Building." "Good!"

Ren Guozhong looked at Li Ziyu and sighed: "Girl, do you think I'm very unkind?" You came all the way to deliver the letter, not only am I not grateful, but I also snatched the formula in your hand, a little ungrateful? ”

Li Ziyu looked at him and didn't speak, but the expression on his face recognized his statement. Now, she felt uncomfortable.

Although he took this trip, he had the idea of repaying his kindness, and he did not expect the Ren family to be grateful to him. However, General Ren's attitude towards her still disappointed her.

It seems that I was a little reckless on this trip, and it is a question of whether I can go back or not. Ren Guozhong is not Ren Xiaohang, he is an iron-hearted old fox tempered in the ups and downs of the Great Ye Dynasty and the iron-blooded battlefield, and he is the helmsman who puts the interests of the family first. It's not a problem to sacrifice a handful of people, and even a few lives of his younger siblings are not as good as a few ants in front of him.

However, at present, he can only cling to the big tree of the Ren family, and has no other choice. She secretly blamed herself in her heart, because she was too self-righteous. Thinking that with the formula in hand, you can negotiate terms with them, naively thinking that you can be invincible.

However, it is easy to say that if they threaten the lives of their younger siblings, can they really turn a blind eye? The answer, of course, is no.

Just when Li Ziyu's heart was overturned, Ren Guozhong's slightly low and old voice sounded in the study. (To be continued.) )
