The blacksmith shop is at the end of this road, and at this moment the scorching sun is shining, and the morning market on both sides is miraculously still not dispersed... Messy vegetable leaves and watermelons that had somehow been scooped were scattered on the ground. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

The mess on the street made Lu Chuan's footsteps pause. She stayed in Chang'an for six days, and she didn't go out often in the past six days, although she didn't go out often, she also knew that the security in Chang'an was still good.

Is this scene being robbed?

Robbers, but not like ...... Those people only cared about cleaning up their stalls in silence, and did not rush to report to the officials.

Lu Chuan walked to a stall and was about to speak, but the aunt immediately raised her hand to stop her steps: "Don't come here!

Lu Chuan frowned, she looked familiar with this person, and she should have watched the incident in front of the Jiang Mansion this morning.

But why was she so frightened when she saw her?

The rest of the people who had not left turned pale and trembled in their limbs.

"This big brother... What the hell is going on?" asked Lu Chuan as he walked quickly to one of the men who was running away in a hurry with a cart.

The middle-aged man paused slightly with some clay dolls in his arms, but still gritted his teeth and walked away without looking back.

In these days, more things are better than less.

Lu Chuan sensed that something was wrong, and this feeling made people feel very bad, as if the murderer was none other than her.

Su Jun sat in the wheelchair with a solemn face and raised his finger to point to the blood under the stall and said, "Look, there are blood marks there, maybe they were scared." ”

Lu Chuan turned his head and stared for a moment.

Judging by the color of the blood, it should have happened not long ago.

Isn't it just before...... At that time, Fan Shigao had just left, and they interrogated the three people in Jiangfu.

At this time, some soldiers in the distance were walking back and forth, constantly questioning passers-by. Soon they walked up to Lu Chuan: "Did you two see any suspicious characters?"

"What suspicious character, what's going on here?" Lu Chuan looked at the two soldiers curiously and pointed to the distance: "There is a pool of blood there." ”

Ah, bloodstains?" the two soldiers jerked their heads to look, and when they saw that they were still the same as before, they shook their heads again.

One of the two soldiers saw that Lu Chuan and Su Jun were both extraordinary, so they explained to them in a low voice: "Ah, that bloodstain is today's thing. At some point this year, a mysterious black-clad gang suddenly appeared in the city..."

"Actually, those of us who are subordinates are just guessing, and these gangs are working against our General Han. Several people are killed every certain amount of time, and each time they kill a person, they leave no corpse but a pool of blood. Coming and going, the common people were frightened. If you see anything suspicious, report it to us. General Han said that the person who found the clue would be rewarded with five hundred taels!"

The two men looked at the depressed street scene again, and when they saw that they could no longer find any valuable information, they turned and left.

Oh, the gang in black?

Suspicious person......

Lu Chuan's eyes lit up immediately, and a corpse in front of the Jiangfu Gate was also taken away silently.

Could these people be the same person?

Lu Chuan looked at the figure of the soldier leaving, and finally didn't say anything. Can't you tell them that there is a female corpse missing in front of Jiangfu, and let them find it again?

Absolutely not.

Su Jun tugged at her sleeve and said softly: "It has nothing to do with you, so don't bother thinking about it so much, let's heal Lord Jiang quickly, Chang'an has been delayed here for too long." ”

"Hmm!" Lu Chuan nodded.

The further you go, the fewer shops become. Su Jun asked suspiciously, "Aren't you going to treat Lord Jiang, why did you come to such a remote place?"

"Well, I'm going to the blacksmith shop, this time Lord Jiang's illness is to make a small stent around the heart, from the arterial blood vessels into the problematic blood vessels near Lord Jiang's heart. ”

"Huh?" Su Jun was taken aback. Immediately asked, "How do you put it?" The key is that many blood vessels are hidden, how do you know if they are in the right place?"

Lu Chuan said mysteriously, "You'll know when the time comes." ”

Besides, this little shelf is not something that can be made casually. Because it is something that is placed inside the human body, the material must be extra particular, and everything must be made in strict accordance with the manual left by the mother.

In order to facilitate the production, she also carefully drew the drawings.

After Lu Chuan told the blacksmith what he needed, the blacksmith's eyes widened.

"Ah, girl, this thing is too small, it's really hard to do, can it be bigger?"

"No way?"

"What are you used for?"

"I can't reveal this for the time being. Just do it...... You need to find all the materials first...... Here's how to make it. ”

Lu Chuan unfolded the drawings. This kind of bracket is an extremely small and long metal tube like a tea stalk, the tube body is made of a grid, the head is small, and Lu Chuan has slightly modified a mechanism under the head, as long as a little force, the tube body will expand and stretch like an umbrella.

It's ingenious and new. The eldest brother of the blacksmith shop took it in his hand and looked back and forth, pondering it.

"Cheng, if you come back in two days, I'll try to do it for you. ”

Two days passed.

Lu Chuan is here again.

The thrashing of ping-pong came from inside the room.

The blacksmith is open as usual. Lu Chuan walked up to him and stopped, the middle-aged man was tall and dark-skinned, and he was waving his arm to spark an iron pillar-like object.

Lu Chuan said loudly: "This big brother, I'll pick up the small bracket ordered the day before." As he spoke, he took out a deposit note from his sleeve.

A small stand from the day before?

The man put down the hammer in his hand, took the sweat towel on his shoulder to wipe his sweat, cleaned his hands, and then took the bill given by Lu Chuan and looked at it.

Well, there's such a job. But......

"Little girl, what you want hasn't been made yet. He said frankly and stopped, and looked carefully at the Hou Ye who was sitting in a wheelchair, and saw that he had an extraordinary appearance, a face like a crown jade, and an amiable attitude, not like a troublemaker. explained to him with a sincere face: "Don't be angry, what you said, not to mention whether it can be made, just the raw materials, I ran for a day." I guess this master knows-"

As he spoke, he deliberately lowered his voice.

"The raw materials that the little girl wanted, nickel and white copper, are very precious, and the only little output is also controlled by the Ministry of War, either for the production of weapons, or for entering the palace and giving it to it, and you can buy some outside in the past. But today, the control above is extremely strict, and not a single cent is no longer taken out. So it's really hard for us ordinary people to get it.

So the day before yesterday, I secretly asked an old friend from the military department to help me keep an eye on it......"

(Note: China already had nickel cupronickel in ancient times, which was the world's earliest nickel-containing copper alloy and an important invention in the history of ancient Chinese science and technology.) There are slight references here, but it does not suggest that ancient humans were able to extract nickel. Look around, Haihan~)
