The moment Zhu Houxi pushed open the door of the study, he saw a young girl sitting behind the bookcase and burying her head in writing and drawing, and couldn't help but be slightly stunned.

The girl behind the bookcase is none other than He Zhi'er, the little girl is obviously immersed in her own world, and she didn't even notice that the study door was opened, she still lowered her head, and the charcoal in her hand was rustling on the rice paper.

Zhu Houxi glanced at He Zhi'er thoughtfully, then waved his hand to signal the two little eunuchs to close the door of the study, and then walked lightly to the bookcase to look at it, he was very curious about what He Zhi'er was drawing, and he was so engrossed in painting.

When Zhu Houxi's eyes fell on the rice paper, his face was suddenly full of question marks, which ...... What are the paintings?

It turned out that the rice paper was full of various graphics, all of which were three-dimensional views, including sectional drawings and projection drawings of various parts, as well as densely packed values. Oh, it's not that I don't understand everything, at least Zhu Houxi understands the Arabic numerals marked on it, after all, Xu Jin taught him before.

Zhu Houxi watched He Zhi'er skillfully draw figures, calculate values, both curious and surprised, although he couldn't understand these figures, but also vaguely felt that this was very remarkable, at least let him draw, without rulers and other tools, he couldn't draw such a straight line, such a circle......

Fear of the unknown is the common nature of human beings, people are like this, they always have a sense of awe for things they don't understand, at this time, Zhu Houxi, this kid, looked at He Zhi'er again with admiration, this girl who looks a few years younger than herself.

Although He Zhi'er is still thin and thin, her chest is flat, but she is still a little fleshier than at the beginning, her skin is fair, her eyes are like paint, and she is even more beautiful.

Zhu Houxi, this kid, looked at it for a while, and turned a little red and hot, took his eyes off He Zhi'er's face, and suddenly saw a book next to the bookcase, so he picked it up and looked at it, and found that there were also a lot of graphics drawn on it, but this time he understood it, because these graphics are the overall map of the Franc machine artillery.

Zhu Houxi turned the pages one by one, but the expression on his face became more and more strange, because there were dozens of large and small Franc machine guns painted on it, and according to the figures marked on the side, there were not only super heavy guns weighing tens of thousands of catties, but also fortress guns weighing thousands of catties, as well as ship-based ships and vehicle-mounted guns weighing hundreds of catties, and even small cannons weighing dozens of catties, and individual guns weighing more than ten catties, all of which were rear-loading Franc cannons.

Unconsciously, Zhu Houxi turned to the last page, and found that this page drew a very strange thing, with a fire chamber at the bottom, which looked like an iron pot filled with water, and a transmission gear next to it.

Zhu Houxi scratched the back of his head and subconsciously asked, "What is this, a new-style stove?" ”

Zhu Houxi realized that something was wrong after asking, and his eyes hurriedly looked at He Zhi'er, who would have been startled, but He Zhi'er looked up at him calmly, lowered his head and continued to write and draw.

Zhu Houyu touched his nose inexplicably, he really doubted that he was transparent, and the other party didn't see him at all, but at this moment, He Zhi'er raised his head again, looked at Zhu Houyu blankly for two seconds, and his expression of fear spread on his little face at a speed visible to the naked eye, and he bounced up violently, and exclaimed, "You...... Who are you? How did you get in here? ”

Zhu Houxi couldn't help but be speechless, daring to love this girl only reacted now, but seeing the other party's scared look, he hurriedly waved his hand and explained: "Don't be afraid, I ...... I'm not malicious, hehe, your name is Zhi'er, right? ”

Zhu Houxi had already heard from Jinyi Wei about He Zhi'er, and Xu Jin had also mentioned it in his private letter to him, so from the moment he saw He Zhi'er in the study, he vaguely guessed the identity of this woman.

He Zhi'er saw Zhu Houxi's kind smile and beautiful person, not like a bad person, she couldn't help but settle down a little, and asked curiously: "Who are you, why do you know my name?" Why did they let you into my brother's study? ”

Zhu Houxi rolled his eyes and said with a smile: "I'm your brother-in-law, your brother is taking a nap, I just wanted to go to the study to read a book, but I didn't expect to meet Sister Zhi'er here, aha, it's a coincidence!" ”

He Zhi'er said suspiciously: "You are my brother's brother-in-law?" So how many brothers-in-law does my brother have, the day before yesterday, there was a three-gun brother who is also a brother-in-law. ”

Zhu Houxi's face did not change and said: "Xie Sangun is my brother, my name is Sigun, the fifth child of the Xie family." ”

He Zhi'er blinked her eyes and said: "One sword, two swords, three guns and four guns, hey, it seems that you are really my brother-in-law, but Brother Four Guns, why don't you look like Brother Three Guns and Brother Two Swords at all?" Brother Sangun is tall and strong, and his martial arts are strong, your skin is whiter than Zhi'er, and you look better than Zhi'er, it's so girly! ”

Zhu Houxi's smile suddenly froze, and he said curtly: "Three guns, his ambition is to be the champion of Chinese martial arts, he has been practicing martial arts since he was a child, so he looks tall." Myself...... Cough! ”

Zhu Houxi opened the folding fan and shook it very coquettishly, and continued: "I am determined to be named in the gold list, I have been reading poetry and books since I was a child, and I am full of talent, so it is not surprising that I look a little beautiful, and I have poetry and books in my belly." ”

He Zhi'er nodded abruptly and said: "It turns out that Brother Sipao is also a scholar, my brother is fifteen years old, and he is a talented man at the age of eighteen, so he is amazing!" ”

Zhu Houxi shook the folding fan and the old god said in the tunnel: "What is the Tanhua and the first, your brother's Tanhua is also me...... Ahem, in fact, it is as simple as finding a bag to pick up the first champion! ”

He Zhi'er pursed her lips and said, "I think you are bragging, how old are you, and what fame have you achieved now?" ”

Zhu Houxi said cheekily: "I am seventeen years old, and I am still studying hard in the cold window, and I will show my hand in the coming year, and I will not be able to win the sixth yuan champion and the first." ”

He Zhi'er rolled her eyes cutely: "Then you are still white, you haven't even been admitted to the Tongsheng exam, you are a braggart king, you are really ashamed!" ”

Zhu Houxi's face was slightly embarrassed, but he was not annoyed at all, but felt very interesting. It's no wonder that since Zhu Houxi became the emperor, he has been facing a group of trembling palace maids and eunuchs all day long, and even the queen concubine usually abides by etiquette and is careful when she says a word, let alone laughing and degrading him in person.

So at this time, chatting with He Zhier as an equal, Zhu Houxi, this kid, felt comfortable and comfortable, and there was a strange kind of joy in his heart.

"Hehe, you just brag to me, and when Xiaosheng takes the lead, he will definitely surprise you." Zhu Houxi said triumphantly.

He rolled her eyes again and sat down to continue drawing her drawings. Zhu Houxi was a little disappointed when he saw this, leaned forward with a flattering face, pointed to the strange-shaped "stove" on the book and asked, "Sister Zhi'er, what is this thing you painted?" ”

"Steam engine!"

"What? Angry chicken? It's unheard of, it's not like a chicken at all! ”

"Poof, it's a steam engine, a machine, not a chicken!" He Zhi'er couldn't help but laugh.

Zhu Houxi's eyes lit up, and he hurriedly asked, "Sister Zhi'er, dare to ask about this steam...... What is the machine used for? ”

He Zhi'er shrugged her nose proudly and said, "It can make the carriage without horses, and the warship without sails, anytime, anywhere, and go as you want." ”

Zhu Houxi couldn't help but gasp and blurted out: "It's really fake, you won't be bragging, right?" ”

He Zhi'er glared at Zhu Houxi unhappily and said, "You are bragging, braggart king, my brother said that if he can, he will definitely be able to." ”

Zhu Houxi suddenly realized: "It turned out that this thing was Xu Jin...... Ahem, my brother-in-law came up with it, so I'll just say it, no wonder. Tsk, if it's true, then this competitive chicken is also amazing, it can be called an invincible magic chicken! ”

He Zhi'er couldn't help but giggle when she heard this, Zhu Houxi saw that she made the other party laugh, she felt a little proud in her heart, and said with a smile: "Sister Zhi'er, you really look good when you smile!" ”

He Zhi'er's little face was slightly red, she glanced at Zhu Houxi, lowered her head and continued to draw her drawings.
