Frankmir cautiously took the brass musket from the warden's hand.

The delicate carvings of brass and silver on the musket show the vulgar and messy Baroque style, perfectly showing the glitz and splendor of equilibriumism.

On the barrels of the three brass guns, the three-headed beast "Cerberus" leaped into the air, and its hideous roar and furious appearance came to life, worthy of its title of hell's watchdog. The magnificent tail of the dragon of "Cerberus" descends along the butt of the gun, dancing with a surging and fierce passion.

Seven pythons twisted and coiled around the streamlined body of "Cerberus", and also restrained the seven beautiful silver-white angels. This brass musket called "Gustav's Heart" is full of religious colors of the classical era, and it is very rebellious and shows the heretical style.

"This is the mercury bullet." The warden put on leather gloves in a wooden box and took out a silver object that looked like Cuban cigar smoke from the wooden box.

"Such a long bullet?" Frank Mire asked, taking the silver object from the warden's hand.

"It's a little longer, but I'd advise you to put it in the magazine. Mercury is very toxic and easily absorbed by human skin. When you use these mercury bullets, try to avoid contact to prevent mercury poisoning yourself. The warden took off his leather gloves and said.

"How are these bullets made? I think there are also fine carvings on it, which must be expensive. Frankimir did not take the warden's admonition seriously, which was the recklessness and fearlessness of the young man, but this unscrupulous behavior always made the young man suffer.

"It's very simple, as long as you have mercury, you can get a bullet like this." A smug smile spread out on the warden's bitter face.

"What? Do you want to do it yourself? I don't have the skills to do that. ”

"Of course you don't. This is the only mercury bullet in the world made by the 'Heart of Gustav'. ”

"You say this musket can make its own bullets?"

"That's right. Before you take the 'Gustav's Heart' and enter the cave, it seems that I need to explain to you how this 'Gustav's Heart' works. First of all, you need to know that the lily cross above the middle barrel is the safety valve of this musket. The four ends of the cross, which are closed, open only one trajectory, open two projectiles at the same time, and open three projectiles. This is very important, you must know that this gun is used to attack mechs, and it may be useless. Mercury bullets cannot penetrate heavy armor, but will cause the bullets to turn into liquid mercury again due to the violent impact. But for living organisms, it is the world's deadliest weapon. This is true for the cyborg soldiers, and it is the same for us humans. Therefore you must be vigilant and at no time can you let this gun go off, otherwise it will be you. Or your teammates, they may completely lose their lives because of this unintentional misfire. For us human beings, if we are hit by an ordinary bullet, if it is not fatal, we will at least have a great hope of healing, and we will not lose our lives. But if you are hit by a mercury bullet, there is no hope of being rescued, and the mercury toxin will spread dramatically in the body. The circular part above the trigger is the bullet maneuver, and a total of 100 such bullets can be placed. You have to know that not every shot, a bullet is used. As long as there is a lethal enough dose of mercury to enter the body of the organism, this is sufficient. You can adjust the caliber of the bullet with the rotating nut above the chamber so that a single bullet will be cut into several smaller bullets. I know it sounds a little uninteresting, but it's just the way it is. Between the hammer and the shōmon, the slide of the eagle carved with it is where this strange bullet is made. Just pour the mercury into the ammo slot under the slide cover, and soon it will make the mercury bullet you see on its own and automatically fill it into the slot. To the right of the hammer is a flint machine, and behind it is a spare one, which is enough to last for hundreds of years, which is not only the driving device for firing bullets, but also the source of power for the 'Heart of Gustav'. All you need to do is pull the trigger to get the 'Heart of Gustav' running, and the impact of the flint machine will provide the power that the Heart of Gustav needs. ”

Frankimir wrote down all the instructions of the warden about the operation of the 'Gustav's Heart', he did not want to miss any details, it was obvious that this musket was not an ordinary firearm, if it was an AK47 rifle, Frankimir did not care what the warden said.

Just as Frankmir poured a large beaker full of mercury into the musket's slot, as the warden had instructed, Kafka, dressed neatly, entered the infirmary again.

"Are you still leaving? Everybody's waiting for you, and if we keep grinding, I think we can stay for lunch. Kafka said as he carried the AK47 on his shoulder. He looked like a small arsenal, and the bulletproof vest on his body made him look even more bloated and fat.

"Go, go. Remember to be careful, any mistake can drain your energy, and that would mean death. Be thoughtful, think twice, don't rush in blindly, and hope that you will be able to come back before dark. Kafka, I hope you will not embarrass our Frankimir. The warden said.

Kafka glanced impatiently at Frankimir and said, "How is it possible, I'm not the kind of person who has nothing to do, unless someone picks things up first." ”

"I know your character better than anyone, Yulia stares at Kafka, don't let him mess around." The warden looked at Yulia.

"I think they'll be friendly, they'll be fine, they're not kids." Yulia looked at Frankimir and then at Kafka, and although she said this, she did not think it in her heart.

"The stubbornness of adults is sometimes more incomprehensible than that of children."

"I don't think that's going to happen." Kafka said, his torch-like gaze glancing at Frank Mire. Frankimir was too busy fiddling with his musket to notice Kafka's gaze.

Kafka noticed the 'heart of Gustav', but he didn't know what kind of logic it was at this time when Frankimir was still fiddling with a furnishing from more than a hundred years ago.

"Go quickly, time is precious and don't delay, good luck to you. I should almost have brought in Professor Saul to arrange the funeral for our comrades who were killed, and it will take some time. ”

Frankimir and Yulia didn't say anything more, and Yulia called in some of the guards to take care of the warden, and left the infirmary with Kafka.

When they came to the entrance of the cave, the remaining seven team members were already fully armed and ready to go. As soon as Frankimir and Yulia arrived, they could set off immediately.

Kafka thought that Yulia should not wear such a white coat and follow them into the cave, which was very inconvenient, and if there was any danger, it would be very troublesome. So Kafka asked people to find a one-piece suit, the standard prison guard's overalls.

Yulia gladly accepted the offer, changing out of her white doctor's coat and wearing a close-fitting brown leather and navy blue cloth prison guard overalls.

It is a garment made of leather and plant fibers that is both durable and easy to move. After tightening the overalls up and down, large and small, nearly 20 belts were folded, this costume reflected Yulia's perfect figure more vividly and exquisitely. Several metal brass rings on the leather for hanging objects glitter in the light of the storeroom light. Two rows of square nails extending from the cuffs to the neckline make this cheap dress get rid of the original inferior charm.

At this time, Kafka found Yulia an armed belt full of loose ball grenades and a bulletproof vest full of magazines, and asked her to choose two M900 pistols and an AK47 rifle.
