The Force is a nightmare for all humans, and the strength of every mature Force is higher than that of a high-level mutant beast, even the masters of human strength and external strength do not dare to fight against a mature Force beast alone.

When the Force grows to a certain stage and the Force saturates its body, most Force beasts will choose to give birth and give birth to a second generation of Force Beasts, so as to disperse the Force in their bodies to form a Force herd, and they themselves become the Force mothers. The Force Beast that becomes the mother will have its strength reduced in the short term due to the dispersion of the Force, until the Force is saturated again, and then it gives birth again, so as to break through its own limits in this cycle.

However, a small number of Force beasts do not choose to give birth after the Force is saturated in their bodies, but continue to absorb the Force, more than half of these Force Beasts will die due to too much Force explosion, but a very small number of them break through the limits of the body to complete the transformation, this part of the Force is called neutered. Every molt of a neutered body is a process of breaking through the limits and becoming stronger.

What Zhu Yuan was holding in his hand was the shell left by the molting of a certain sterilized body, although it was less than one square meter in size, it was enough to make a Rubik's Cube.

I have to say that Xian Renxing's luck is really good, this precious material can be collected by him. Zhu Yuan sighed with emotion, and his hand was quick to complete the division of the material.

The Rubik's Cube conceived by Zhu Yuan is not large in size, it can be held on the palm of the hand with one hand, and the Rubik's Cube is divided into three layers, each layer is composed of nine square squares, three in length and three in width, and the three layers of squares form a larger cube. The center of each block is hollow, except for the one-way opening of the bottom block, the other two layers are two-way openings, and Zhu Yuan inside and outside the block is carefully wrapped with sterilized body remains to increase the flow of force, and tear crystal stone and stone pine wood are divided into two layers to fill the inside of each block.

The three layers of twenty-nine blocks are combined to form the magazine of the Rubik's Cube, providing bullets for the charging of the Rubik's Cube, and Zhu Yuan has added a layer of kinetic energy to the top layer, this time just like the barrel of a scorpion, it can play the function of guiding the shooting, and it can also provide the kinetic energy of the shot.

This layer is still composed of 9 independent flat blocks, he can adjust their respective muzzles as needed, and even when Xian Renxing reaches the external strength stage, he can let the nine shooting blocks of the kinetic energy layer separate from the Rubik's Cube, as for the distance of separation, it depends on how far Xian Renxing's external strength can be maintained at that time.

"Therefore, the value of the Rubik's Cube can only be reflected after Xian Renxing becomes an external force. There is one last step left. ”

After Zhu Yuan put the nine Origin Energy Crystals that had been prepared one by one into the groove energy at the bottom, he saw the light blue Force circulating in the Rubik's Cube, the joy in his heart could no longer be suppressed, and he laughed happily, this Rubik's Cube was his most successful and proud masterpiece so far.

Xian Renxing, who was already waiting outside the door, heard Zhu Yuan's laughter, and his heart was as uncomfortable as a cat's claw, but he didn't dare to go in without permission, what if he was accidentally disturbed by himself, resulting in the failure of the production, not to mention the fifty gold coins that he put in for nothing, the weapon he had in his heart was gone, and there was no place to cry at that time.

"Deputy Xian, come in." After Zhu Yuan finished laughing, he shouted to Xian Renxing outside the door.

As soon as Xian Renxing heard him, he rushed to the door, pushed the door open, rushed to Zhu Yuan, and asked impatiently, "Did you succeed?" ”

Of course, he himself knew that he was asking nonsense, didn't he see that Zhu Yuanxiao's mouth was about to crack to the back of his head?

Sure enough, I saw Zhu Yuan hand over the Rubik's Cube in his hand and said:

"The Rubik's Cube, filled with 27 bullets, nine rounds per layer, but nine rounds can be fired at the same time, and the firing direction can be adjusted. Nine charging crystals, 27 bullets can be charged at the same time each time, and the charging time needs to be experimented by yourself, but it should be similar to a scorpion, and it can be replaced when it is used up, and nine kinetic energy crystals do not need to be replaced. ”

Xian Renxing took the Rubik's Cube, and after learning to control it simply according to Zhu Yuan's guidance, he couldn't put it down, and he couldn't wait to experiment.

"Deputy Xian, sell me some materials left." Zhu Yuan pointed to the rest of the table and said, he didn't want to give up such a good material.

"Don't buy it! I've sent you. Xian Renxing laughed, holding the Rubik's Cube and leaving.

"Vice Captain Xian, this material is fifty gold coins cheaper, at least one hundred and fifty gold coins."

Zhu Yuan saw that Xian Renxing was in a hurry to test the Rubik's Cube, and reminded him that he knew that Xian Renxing was a person who valued love and righteousness, and he didn't want him to owe his friends.

Xian Renxing listened to Zhu Yuan's words, paused, nodded, and left. The most important thing for him now is to test the performance of the Rubik's Cube, money is not a problem, just go back and make up for it.

The making room was quiet again, Zhu Yuan looked at the sterilized body corpse lying quietly on the table, and only felt that his hands were itching, but what should he do?

Zhu Yuan was a little worried, the remaining materials were not large, although he could make another Rubik's Cube, but Zhu Yuan felt that even if he did it, he would not surpass the one just now, and the one just now was already his super level performance.

"What to do?"

Zhu Yuan muttered and fiddled with the leftovers left over from cutting and making the Rubik's Cube in his hand, the leftovers had six sides, but miraculously they were symmetrical in pairs, and Zhu Yuan randomly pieced together to form a rectangular black box.

"Let's just practice carving."

Zhu Yuan laughed at himself a little, the box has six sides, twelve sides on the front and back, and it will be used as a box if it is obsolete. Zhu Yuan thought boredly, took out the Liuhuo cloud velvet pen for engraving and the Venus sand ink, after some preparation, Zhu Yuan calmed down the wonderful feeling in his heart after making the Rubik's Cube, and after using the Liuhuo cloud velvet pen to dip a little Venus sand ink, he held the pen in the corner of the black box.

The moment he clicked, the chaotic energy in his body suddenly flowed automatically, and he entered the Liuhuo Cloud Velvet Pen along his arm, and entered the Venus Sand Ink, which seemed to have spirituality and flowed along the twelve ridges of the black box under the impetus of the strength.

When the twelve ridges were all dyed with a little starlight, the strength in Zhu Yuan's body seemed to have found an outlet again, and when Zhu Yuan didn't have time to stop it, he spontaneously drew a regular line on the three sides of the box, and then turned around and returned to the body along another line.

It's a long story, but in fact, it only happened in the blink of an eye, and before Zhu Yuan could react to suppress the strength in his body, the outflow of energy turned around and came back.

Zhu Yuan keenly noticed that the strength of the return had changed, and it no longer had the power of rules and became pure, just like dyeing ink and water, and the ink color became clean again after being sucked away.

"It can't be."

Zhu Yuan said to himself in disbelief that there has always been a hidden danger in his body, and he will not dare to use the strength in his body at will at that time, and this hidden danger is the power of the rules in his body.
