If Mordin stood still, the orientation would not be mistaken, and Mordin could control the Void Sword like a mouse on a computer screen. But as soon as Mordine turned or jumped, the bearings were immediately confused.

This is the restriction brought by Mordin's lack of access to the Yuan Shen Realm and his lack of external divine sense, which is very inconvenient when fighting against the enemy. Not only the direction, but also the accuracy of the attack is not guaranteed.

But in any case, this sword was the first magic weapon that Mordin obtained, and from then on, he had a weapon for self-defense, and if he encountered those black-clothed men who attacked him again, Mordin was sure that he could use the Void Self Sword to give them a counterpoint.

The next step is to master the control of the flying sword. In order to solve the confusion of the two coordinate systems of the real scene and the sea scene, he came up with a solution, which is to use the pointing of the tip of the sword as the unified direction of the two coordinate systems, no matter how he jumps and turns in circles, the direction of the tip of the sword is fixed, so as to roughly solve the problem of confusion in the coordinate system.

There is also the issue of attack accuracy, which requires repeated practice, and there is no other shortcut.

He also tried to hold the sword in his hand and make a chopping motion, but the result was not very satisfactory. Because this sword is so heavy, it is hundreds of kilograms long at 1 foot. Although his modified muscles are very strong, the sword is held in his hand and it takes both hands to wield it.

There is also the problem of the size of the sword, usually when you go out, especially to school, you can't always take a sword to class. Mordin also thought of a way to make the Void Sword smaller than a pin, pinned to the belt, and it was easy to take it out when it was time to use it.

School is still ten days away, and Mordin doesn't plan to go out, wanting to use this time to be as proficient as possible in controlling the flying sword. He made the blade of the sword only 2 inches long, and then painted bullseyes on the surrounding walls, and then practiced against them repeatedly. His progress was very fast, first he controlled the flying sword to shoot more and more bullseyes when he was sitting still, and finally he could also shoot the bullseye when he was jumping around the house, and the time for aiming at the tip of the sword became shorter and shorter, almost to the extent that he was handy.

But his walls were full of holes, which he had pierced by the sword when he could not grasp his strength.

"It's too hard to practice indoors, and it's better to go up the mountain to practice swords, because the place is big and spacious, and you're not afraid of poking holes. Thinking of this, he picked up his portable phone, shrunk the sword and put it in his jacket pocket, and went out.

"Auntie, why is this tree broken? Could it be that hail and strong winds were blowing some time ago?" He saw that the orchards on the hillside were in shambles, and the branches of the fruit trees were falling all over the ground as if they were beating towards the northern ice.

"The next time there is a fight between two masters here, these people don't know how to cherish fruit trees at all," he complained.

Qingxu Dao Chang, who was sitting in the study reading a book, suddenly sneezed inexplicably.

Mordin carefully walked through the orchard, and then began to exert his strength under his feet, and ran up the stairs up the hill violently, and the flowers and plants on the side of the road shook like a whirlwind.

It took less than a minute for Mordin to reach the top of the mountain, the midsummer sun was very hot, but on the top of the mountain, there were still sparse tourists.

"Forget it, let's go into the cave," He ran into the bushes, lifted the stone slab, and got into the hole, and in a few moments he reached the hole behind the boulder.

"Jin Yizhi will that strange old man come here often?" He was a little worried, this was his private territory, and he didn't want other people's frequent visits to disturb him.

He took the little sword out of his pocket, placed it on the stone table, and then with a thought, the little arrow flew out with a whoosh, and plunged headlong into the mist below the cliff, out of sight.

Mordin was in a hurry, he hurriedly hooked up with the little sword, fortunately, there was still a connection with the sword in the sea of knowledge, and the little sword turned around and reappeared in his field of vision.

He no longer dared to fly his sword too fast, in case he flew away and fell into the cliff, the master would not spare him.

So he had to slowly put the money out and carefully do a test, and it found that the distance between him and the sponsor should not exceed 500 meters, and once it exceeded this range, it would lose control.

Knowing this restriction, he began to control the sword with confidence, and the shop was in and out of the clouds, up and down, which was really fun.

Suddenly, a small bird flew in from the mouth of the cave, and it stopped on the stone table, staring at Mordine warily.

"Maybe he's tired of flying, so he stops and rests for a while," Mordin stared at the bird, and suddenly thought to him.

"Can I let the sword fly with me?"

As soon as the idea came to him, he was so excited that he jumped up from the ground and flew away in fright.

He immediately retrieved the sword, laid it flat on the ground, and became five feet long and a foot wide, and then he stood up, carefully raising the blade.

He felt the blade of the sword move, and it seemed that his feet were off the ground.

"It worked," he shouted excitedly!

"Raise it a little higher. "He kept trying.

The sword body was a foot off the ground, and just as he was about to celebrate, the sword body was tilted violently, and he fell to the ground with a "plop", and his head was hit hard by the stone table.

He sat on the ground and touched his aching head.

"Is there something wrong?"

He raised the blade out of thin air, also a foot above the ground.

"The sword is very stable, huh?"

Strange, why do people stand up crooked?

"No!" he seemed to remember something, and with a light touch of his hand on the side, the sword shook.

"Oh, I see. He figured it out. Your consciousness drives the movement of the sword with the center of gravity, but once the sword is subjected to an external force, the sword body will definitely twist, for example, if you hold one end with your hand, the sword will tilt. In order for it to regain balance, it is necessary to adjust the way the consciousness is driven, adding more drive to the rapier head.

If a person wants to stand on a sword, he must adjust the force that drives the sword body at any time according to the difference between the center of gravity of the sword body and the center of gravity of the human body.

This is not a simple job.

A person's center of gravity changes at any time with the change of body posture, and it is impossible to rely on the brain's perception and then balance the power of the sword body!

"What can I do?"

He pinched his ears with both hands and thought about it for a while, and suddenly a flash of inspiration came to him.

"When I was a kid and practiced cycling, didn't the center of gravity of the body also need to be consistent with the support force of the bike? But when I ride a bicycle, I don't need my brain to think about the position of the center of gravity of my body at all times?

Cycling is a matter of practice;

After practice, the human body is very smart, and he will automatically maintain the support force of the car in a straight line.

So, can I also practice to align my body's center of gravity with the support center of gravity for fitness?

Thinking of this, he rolled over, stepped back on the sword, and began to practice.
