Ye Luo never knew that he could go three days and three nights without sleeping.

In short, since she knocked on the door of the empty old man that morning, she has never stepped out of the Sky Pavilion again.

Kong Lao is worthy of being an experienced refining master, and the spiritual materials he selects are definitely no worse than the alloy steel of the 21st century, whether it is hardness, ductility, heat dissipation, and impact resistance, they are all top-notch.

Heated discussions, close running-in, spiritual materials into the furnace.

In the afternoon of the next day, 100 sniper rifle parts, large and small, were refined by two people. There is one last item missing, bullets.

"Luo girl, the old man thinks it's very bad for you to use gunpowder bullets."

Kong Lao frowned, and questioned Ye Luo's design drawings for the first time, "Gunpowder weapons, for cultivators above the third order of madness, basically have no effect, at most they will break through the skin. Only madness can break through the attacks and defenses of the berserkers, as well as the tough body. ”

Ye Luo thought for a moment and said, "Then replace the gunpowder with madness." However, gunpowder can be stored in bullet casings, so how can madness be stored in bullet casings? ”

Kong Lao smiled: "It's not simple? The old man engraved a divine pattern of storing madness in the bullet casing, girl, you inject madness into it, seal it, and you can keep it for a month. ”

"Divine tattoo?"

Ye Luo's golden eyes lit up.

Kong Lao nodded and explained: "Luo girl, you have to learn the introductory knowledge of refining with me, and there is also a break time." The refining weapon is divided into two important parts, one is to refine the shape of the weapon, and the other is to depict the divine pattern in the weapon. There are no weapons engraved with divine patterns, just mortal soldiers; And the weapons that have depicted the divine pattern are spiritual weapons. ”

Ye Luo listened intently.

"If you want to truly become a refiner, you must learn to depict the divine pattern. The Divine Pattern is the soul of the spiritual artifact. It is the foundation of every refiner's survival. Kong Lao smiled slightly and said, "You are now my apprentice, learning to refine the shape of weapons. In the future, when you have cultivated beyond the ninth order and become a saint-level master, you can start to learn to depict the divine pattern, and then I can accept you as a disciple and teach you the divine pattern I have mastered. ”

Ye Luo was extremely excited, and bowed respectfully to the empty elder: "Thank you, Master."

"Don't be in a hurry to apprentice first, the divine patterns I have mastered are also very basic and crude." The empty old man smiled bitterly with regret.

"Basics? Lower? ”

Ye Luo was very surprised, "Master Kekong, you are the top refiner in our Fire Crane Country!" ”

"So what?" Kong Lao shook his head helplessly, "That's right, just by relying on a few extremely crude divine patterns, I am enough to rank among the top refiners in the small country of the Fire Crane." Luo girl, the outside world is far wider than you think! ”

Ye Luo was greatly stimulated.

I haven't come back to my senses for a long time.

At this time, Kong Lao had already condensed his soul power and concentrated on carving the basic god pattern in the bullet casing.

About twenty minutes to complete one.

For a whole afternoon, Kong Lao exhausted all his spiritual power and soul power, and finally carved the twenty bullet casings with the divine pattern of gathering madness.

"No, I'm so tired, I need to go get some sleep......"

The empty elder's voice became lower and lower, his head tilted, his body slipped, and he fell to the ground and fell asleep.

Ye Luo was extremely moved.

She carefully supported the empty old man, placed him on the soft couch in the bedroom, waited for him to take off his shoes, and helped him pull the quilt.
