Behind the cave, in the refining room in the mountain wall, the fire in the refining furnace was blazing, and there was a small bronze kettle above the refining furnace, and the billowing orange smoke gushed out of the bronze kettle, and then was sucked away by the prohibition placed above the refining furnace.

Chen Jingzheng stood in front of the bronze kettle, watching the liquid in the kettle tumble and boil, the liquid was dark red, like flowing glass, and the inside showed flashing red light from time to time, and bubbles constantly appeared on the surface of the liquid, bulging, expanding and then bursting, releasing orange smoke.

On a nearby stone platform, a stone pestle was grinding the red crystals in the stone mortar into powder under the control of invisible mana.

Chen Jing is refining sharkskin glue, and the refining method is still what he found from the "Four Seas Yuchen Book", he promised to make a ball for the little beasts, and the sharkskin glue is tough and elastic after solidifying, which is suitable for making the inner tube of the ball.

Shark skin glue was originally used to make boat-shaped magic weapons sailing in the water, although there are two words in the name, in fact, it is made of the tendon of the monster as the main material refining, with it made of tough and waterproof, comparable to shark skin, so it is called sharkskin glue.

Chen Jing saw that the bubbles coming out of the liquid in the bronze kettle gradually decreased, and after a while, the bubbles disappeared completely, and there was no smoke floating out of the kettle, he thought about it, and a stream of mana rolled up the stone mortar, and poured the red powder in the stone mortar into the bronze kettle.

At the same time, another mana rolled up a jade rod and quickly stirred it in the bronze cauldron, Chen Jing controlled the refining furnace to reduce the temperature at the same time, and the raging flame retracted to the bottom of the refining furnace in a flash.

Under the stirring of the jade rod, the red powder gradually dissolved into the liquid in the bronze cauldron, and the dark red liquid gradually shone bright, and finally turned into a magma-like red red.

Chen Jing nodded, the sharkskin glue in this kettle was refined, and the sharkskin glue would solidify when it cooled down, and he controlled the refining furnace to maintain the temperature in the bronze kettle.

Then his mind moved, and a wave of mana rolled up a ball of sharkskin glue from the bronze kettle, and flew towards the stone platform, there was a square stone block on the platform, and a hemispherical depression was dug out on the stone, and Chen Jing threw the sharkskin glue into the depression on the stone with his mana.

He took out a mana and rolled up another identical stone on the stone platform, and the two mana forces brought the two stones together, and the two hemispherical depressions in the stone formed a spherical space.

The invisible mana continued to shake the two stones together, so that the sharkskin glue flowed on the surface of the spherical space, and the sharkskin glue that touched the stone was glued to it and slowly solidified, and soon the sharkskin glue was stained with the surface of the entire spherical space in the stone, and gradually solidified, forming a spherical film.

Chen Jing sensed that the sharkskin glue in the stone was completely solidified, and the two stones were also glued together, he picked up the stone and walked to the door of the refining room, opened the stone door and shouted, "Pine cone!" ”

A cyan shadow jumped out of the back window of the second floor of the pavilion, and in a few steps it reached the door of the refining room, and the little green linbeast looked up at Chen Jing, raised its front legs and jumped.

Chen Jing handed the stone to the pine cone and said, "Come, turn this stone into stone powder." ”

The mana of the pine cone gushed out and took over the stone, and then the little green linmon spewed a mouthful of yellow light at the stone in mid-air, the stone disintegrated, the stone powder suddenly fell from the sky, and a crimson ball emerged from the stone powder.

"Well done!"

Chen Jing stretched out his hand and made a move, a wave of mana rolled the ball over, he took the ball in his hand and looked at it carefully, patted it again to try the elasticity, and saw that Songguo was looking at the red ball curiously, and said: "This is the ball made for you, it is not done yet, and it will be able to play tomorrow." ”

Let the pine cone go back to rest, Chen Jing returned to the refining room, this ball feels that the toughness and strength are enough, but the elasticity is insufficient, because the air pressure inside the ball is relatively low.

This is easy to solve, Chen Jing took a little sharkskin glue and solidified it to make a pump hole, then poked a small hole in the ball, installed the pump hole at the small hole, and glued it with sharkskin glue.

Blowing into the ball, Chen Jing took the ball and patted it, this felt right, he chose a tough, light demon animal skin, cut this blue-black leather into a suitable shape, and glued it to the surface of the ball.

And fill the gaps between the leather with some sharkskin glue, so that such a stretchy, large, floating, and durable ball is ready.

Chen Jing threw the ball with satisfaction, the diameter of the ball was more than a foot, and between the pieces of blue-black leather on the surface were the lines formed by red sharkskin glue, as if there was hot magma in the center of the ball that had cracked the blue-black surface.

Chen Jing thought that he should give this ball a name, this is for the little beasts to use on the top of their heads, it stands to reason that it should be called "head ball", but this name always feels a little wrong.

Looking at this appearance and appearance, it is not an exaggeration to call it "Spitfire Meteor", but this name is a bit too long, and the round ball is full of elasticity, so it is simply called "Pinball".

He put the remaining sharkskin glue from the bronze kettle into a stone bowl, and the solidified sharkskin glue will melt again when heated, and the sharkskin glue can be kept for later use.

In the afternoon of the next day, Chen Jing saw several small beasts playing in the pool on the second floor of the pavilion.

Chen Jing slapped his palms, and saw that the little beasts had all looked over, he reached out and wiped it on the storage bag, and with a flash of brilliance, a large round ball appeared in his hand, and the blue-black surface of the ball had dazzling red stripes, looking extraordinary, Chen Jing said to the little beasts:

"This one is called 'pinball', and it's played on the top, just like a gourd."

The little beasts were in a commotion, and they rushed out of the pool one after another, surrounding Chen Jing.

Chen Jing gently threw the marble over his head, gently tossed it twice on his forehead, and then shook his head and pushed the marble into the air above the pool.

The little beasts immediately turned around, rushed down the pool, stepped on the floating platform and chased the blue-black ball in the air, the pine cone was the fastest, it chased to the near of the pinball, and the front legs of the hind legs stepped on the floating platform, and jumped into the air to top the blue-black ball, it used a little more force, and the pinball "bang" bounced up more than three feet high.

Fortunately, this pinball is big and floating, although it is full of elasticity, it does not fly fast, and it does not float far, otherwise with the strength of the little beasts, the ball will fly away without a trace.

Mango kept chasing after Songguo, staring at the pinball, when he saw the pinball flying out, he immediately turned to chase it, and the floating platform under the giant kitten's feet suddenly rolled to one side, stirring up a large splash.

Mango chased under the pinball that fell from the sky, jumped into the air, jumped into the air, the kitten had time to look at the position of the little beasts in mid-air, and then headed up to the pinball, "bang", the pinball flew out, this time the speed was faster.
