"It must be. However, now my mind is a little confused. I need to be alone to calm down." Zhang Lin smiled slightly and said casually.

He felt that he could not directly refuse Qiu Shuang's help, otherwise, if he did it too obvious, it would arouse her suspicion, because before, he never avoided Qiu Shuang when making any utensils. The transformation became too fast, which was not good.

"Then I'll take a leave first. If you need it, then pull the bell and call me." Qiu Shuang smiled and looked at her careful and considerate look.

"I can." Zhang Lin nodded and agreed.

Qiu Shuang went out, and only a few imperial guards and eunuchs who came with Zhang Lin were left in the furnace room.

Zhang Lin didn't trust those new guards and eunuchs. He thought for a moment and made the following arrangements:

"Liu Shen, you will take a few guards to guard the door and window of this furnace room, and do not allow any idle people to approach this place."

"Yes!" Liu Shen agreed loudly. He was working with Zhang Lin for the first time, and he didn't know his personality, so he agreed to his orders very simply without saying a word of nonsense.

"Tinggao, you can take some people to the warehouse to carry some of the various materials." Zhang Lin also told Dan Tinggao in a gentle voice, and gave him a order to get the goods as ordered.

Shan Tinggao agreed and took a group of people to work.

Only Zhang Lin's trustworthy Lu Junyi was still in the small furnace room and protected him nearby without any trivial matters.

After all the preliminary preparations were arranged, Zhang Lin stood in the room and looked up at the four walls and ceiling of the small furnace room. He was observing whether there were surveillance cameras or peepholes. However, he thought that the place he was in was not modern, but ancient. In ancient times, without electricity and network, how could there be such advanced monitoring equipment? Besides, this is an independent house, without left and right, and without the left and right, where did peepholes come from?

It seems that I am really a slut, and I am thinking too much.

He mocked himself, took out the drawings of the crossbow from the bag, spread them on the long table beside the window, and began to carefully examine and study them carefully.

The drawings of the crossbow truck are very complex, including multiple small drawings, each small drawing represents a small part of the crossbow truck.

These drawings were made by Zhang Lin based on his imagination. In fact, he had no need to look at the content and shape of the drawings. However, in order to ensure accuracy, it is still necessary to check the numbers on the drawings. Because there are too many values ​​involved in the drawings, he may not be able to remember all the values ​​completely. If there are any mistakes and errors at that time, it will be troublesome and will be a joke.

However, there were several extremely critical drawings that Zhang Lin never took out. Although those drawings were critical, they were extremely simple, so he could clearly remember them in his mind without looking at them.

In another house dozens of steps away from the small furnace room, there is a room with a very Persian style. The ceiling is painted with blue murals, the door lintel is inlaid with cat's eye stones, and the floor is covered with Persian carpets made of brocade. The interior ornaments are all very strange things, including bronze camels, beast-mouth pots, bronze discs with lifelike characters, full moon scimitars, and a reduced model of the tower of the sky.

This is the private study room that will be the chief supervisor Shar Khan. The so-called private study room is also a relatively mysterious place that ordinary people cannot approach.

Behind the bookcase is a row of bookcases against the wall, and a pair of sterling silver-making cannon bottles were placed on the bookcase. Shahrhan was leaning over the opening of one of the long-necked bottles, staring at the bottle with a focused expression, as if there was something strange in the bottle for him to appreciate.

At this time, Qiu Shuang appeared at the door of the study and reached out to knock on the door, but Shahrhan did not notice it, so she pushed the door and went in by herself.

Because she was too focused on appreciating the bottle, Shahrhan did not notice Qiu Shuang's arrival, nor did she hear the sound of her opening the door.

Qiu Shuang walked behind Shahrhan, reached out and patted his shoulder, and asked in surprise: "Hey, what are you looking at?"

Shahrhan was startled and turned around suddenly, and found that Qiu Shuang was close at hand. His face turned red suddenly, and he looked a little panicked. He hurriedly picked up the bottle cap placed next to him and closed the bottle.

Qiu Shuang was even more strange: "What good things are in the bottle, let me see."

Shar Khan is a man who has been a battlefield for a long time and has a first-class performance. He quickly recovered his calmness and laughed and concealed: "Nothing. It's some of my private items that are not worth seeing."

"What do you have to let me see?" Qiu Shuang said angrily.

Sharhan did not answer Qiu Shuang's question, but instead said to him: "Duke Shun should start making molds. You should go to his place quickly, so as not to miss the best opportunity."

Driven by strong curiosity, Qiu Shuang's stubbornness came up, and she had to look at him. She glared at Shahrhan in a coquettish way and said, "No, I want to go, I want to go inside the bottle before going, otherwise I will not be in the mood to do your business."

Shahrhan had no choice but to shake his head and sigh, and fell helplessly on a chair, stretching his hand to her reluctantly, which meant that she would ask for help.

"This is almost the same." Qiu Shuang opened the bottle cap and put her eyes towards the mouth of the bottle to see what was inside the bottle.

At the first moment of approaching the bottle, Qiu Shuang's eyes were shining with a ray of shock. The bottle was not dark, but full of light. At the bottom of the bottle, it was not flat, but vivid scenes appeared.

In the middle of the scene is a table, with several drawings with various figures on it. Below the scene is a human head, and occasionally you can see his handsome side.

The scene is very familiar, and the people in the scene are also familiar.

No wonder Sharkhan took the initiative to provide Zhang Lin with a special furnace room and couldn't wait to leave in front of Zhang Lin. It turned out that he had planned to understand Zhang Lin's every move through the long-distance peeping channel he had already built. The secretly hidden drawings of Zhang Lin were probably already well-known by Sharkhan.

"You are so awesome. I don't know how to admire you now." Qiu Shuang turned her head and looked at Shahrhan with contempt and anger, and said in a cold voice.

From Qiu Shuang's eyes, Sharhan saw strong dissatisfaction and a faint anger. He knew that Qiu Shuang didn't want him to use methods on Zhang Lin. This was also the reason why he just concealed his concealment and did not want Qiu Shuang to look at the bottle.

However, since the incident has happened and since Qiu Shuang has known the secret, Shahrhan is not panicked or embarrassed. He spread his hands and said in a helpless tone: "Qiu Shuang, isn't this a last resort? Zhang Lin is so cautious about me. If I don't use some means and use my intelligence, how can I learn key skills? How to revive our empire?"

"Have you learned it now? You should no longer need my help, right?" Qiu Shuang laughed coldly in an unconcealed tone.

"Qiu Shuang, don't do this." Shahrhan stood up, put on the airs of being a brother, scolded Qiu Shuang in a stern tone, and then said in a tone with a little regret: "If the skills are as simple as drawings, then I saw it, and I can also say that I learned it because you know that I have the ability to remember everything I have. However, Zhang Lin is in such a safe place and seems to be on guard. I don't think he has taken out all the drawings, and there are key drawings that he hid in the bag and did not take out."

"You think too much, what is he guarding against? How could he know that you are staring at him at such a distance?" Qiu Shuang said in disbelief.

"This is just a feeling and guess." Shahrhan raised his hand and stroked the mouse beard on the corner of his lips, and then he said passionately, "In addition, even if these are all drawings, these drawings are fragmented and scattered, and Zhang Lin did not place them in sequence. In other words, I am not missing a complete drawing. Also, even if I get the complete drawings, it does not mean that I can build the crossbow. Because, from the drawings to the real thing, there is a method and process of conversion. This is not written on the drawings, but requires instruction by example."
