After a few brief calls, the other party picked it up.

"Ada!"

"Who?"

The two words overlapped, Qin Yi fell into a brief silence, and Ada spoke again: "Who are you?"

Qin Yi thought for a moment, then clasped his throat and said, "I've arrived at the door, please come and get some takeaway."

"I didn't order takeout, you ordered the wrong order." Ada replied.

"My call? Aren't you from Building 304, Building 35, Yong'an Community?"

"no."

"Sorry, maybe I got it wrong."

Qin Yi hung up the phone, adjusted his emotions and calmed down again.

It is obvious that I just encountered a situation where I was not suitable to answer the phone at Ada, so I pretended to be stupid and didn't know him.

He was too careless. He shouldn't call back the number just now, but should use a text message to hint the other party to contact again.

I wonder if the accident just now would put Ada in danger.

The phone on the desktop vibrated, and a nerve in Qin Yi's mind seemed to be stimulated. He quickly reached out to pick up the phone, but the text message was not sent by Ada, but Chen Ya, who asked him to go to the alchemy factory.

...

The alchemy factory is the deepest underground of the central courtyard of the Holy See, and is the most core and hidden place of the Holy See. Alchemy weapons are produced in large quantities, and alchemy weapons are the trump card for the battle between the Holy See hunters and vampires.

Qin Yi took the elevator to the bottom. As soon as the elevator door opened, the humid and hot wind that came to Qin Yi's skin felt sticky. He walked out of the elevator and looked around. The strong shirtless man used pliers to clamp the orange-yellow metal liquid, and walked around in meteors, with loud bangs in his ears from the huge mechanical operation.

"Why are you standing there? You can't come?" Chen Ya, who was standing not far away, shouted loudly.

Looking through the sound, Qin Yi saw Chen Ya standing there wearing a black tight vest and shorts, not like a Vatican nun.

"I'd have known that I'd been wearing less clothes." Qin Yi wiped the fine sweat from his chin.

Chen Ya glanced at Qin Yi and let out a cold snorting from her nose: "You dare to be late, believe it or not, I will hit you?"

"I'm not late."

"Dare you still dare to talk back?"

"I... forget it." Qin Yi was speechless.

Chen Ya took out a wrinkled cigarette box from her pocket, took out a cigarette and approached the high-temperature stove next to her, then baked it down, lit it, put it in her mouth: "Come with me! You must master the knowledge of alchemy weapons, otherwise you will be in vain when you come to the Holy See."

Qin Yi followed Chen Ya closely and observed around curiously.

The alchemy factory in Qin Yi imagined should be a very retro iron shop, and all the weapons were handmade by famous craftsmen, but the alchemy factory in front of him was closely following the changes in modern industry and became an assembly line project for machine manufacturing.

The huge machine kept moving up and down, and fixed sword shapes were created. They were forged, added, and cooled according to the established process, turned into pitch-black sword blades, piled up in a basket next to them. Assemblers with quick hands and feet pressed the wooden hilt on each sword with skillful techniques.

"The blades made here are all flame blades. As long as the blade speed reaches a certain level, it can cause the blade to generate high temperatures and even produce flame explosions. This is fatal to vampires. I will take you to see my small workshop now." Chen Ya said.

"Captain, do you still have a small workshop? Oh, I almost forgot that you are one of the best alchemy experts."

"Just know, not everyone has the opportunity to visit my workshop! I opened my eyes wide and looked at it." Chen Ya said angrily.

Qin Yi followed Chen Ya to a room in the corner of the factory. The temperature in the room was higher than outside. Qin Yi couldn't help but start taking off his clothes. Several pairs of men and women were wearing a strange set of equipment and customizing weapons in the small workshop.

The women only wore skirts and breast wraps, and large pieces of skin were exposed. In the high temperature, they didn't care about their body exposure at all.

"Master, are you here?" A woman noticed Chen Ya's arrival, happily took off the pair of glasses on her head and ran forward.

The others stopped their work and came up.

Chen Ya greeted everyone one by one, and went straight to the topic: "Have our crossbow been transformed?"

"It's almost done!"

The female apprentice took a huge crossbow from the table. It looked a bit like an ordinary crossbow arrow, but because it was not installed, Qin Yi could see the extremely complex mechanical structure inside, dense gears and springs, and the filling space for filling gunpowder.

"Qin Yi, this is the crossbow I developed recently. I named it the ghost-killing crossbow. What do you think of this name?"

"I think it's pretty good." Qin Yi said perfunctorily, "What's the use of this weapon?"

"This is a weapon fired by a bullet. Just treat it as a pistol. The speed of ordinary hunters' sword swing cannot reach the realm of producing a flame explosion, but if you use this tool, the fire blade shot can have the flame explosion effect. It should be able to kill instantly against most vampires."

"So powerful?" Qin Yi was a little unbelievable. He, who was once a vampire, knew very well how tenacious the vampire's vitality was. That would never be solved by cutting a hole.

"Of course it's amazing. We have spent a lot of time to make this thing, but the bishop disagrees with me for mass production of ghost-killing crossbows. The flame blade is too rare. It is used to shoot like a bullet. It is troublesome to recover and it is easy to cause waste and loss. Unfortunately... they don't understand the value of ghost-killing crossbows at all." Chen Ya said regretfully.

After saying that, Chen Ya handed the crossbow back to the apprentice and took Qin Yi away from the small workshop.

"What I want to take you to see now is the biggest secret of the Holy See and one of the origins of alchemy technology." Chen Ya said.

Qin Yi felt awe-inspiring in his heart when he heard this. Even though he didn't know what the origin of alchemy technology was, he knew it was a very awesome thing after listening to it.

He had long guessed that this hunter organization that had been around for thousands of years must have some ulterior motives.

When he arrived at the end of the alchemy factory, Qin Yi saw a large iron door more than ten meters high. It was pitch black all over, without complicated patterns, only a huge horizontal bar lock core and regular large gears that were so simple that it was. The two doors were like two giants who had been guarding from ancient times to the present, standing alone.

Chen Ya said a few words to the people guarding the door. With the press of a small button, the two doors made a loud thunderous sound. The gears rotated, and the steel bars like monster fangs slowly moved away from left and right. The door moved horizontally under the action of pulleys to open the passage. There were continuous and violent burning sounds and wailings from behind the steel door!

"What's this sound?"

This suffocating sound made Qin Yi's heart feel tightened.

Chen Ya's face did not change, took a deep breath of cigarettes, and took the lead in walking in: "Come in with me."
