Li Dashou shook very hard, not only his hands, but his whole body was shaking. If he wasn't very excited, he wouldn't have been like this.

Wu Zhongyuan was also very excited, but he never showed it. He smiled and took the cloth bag, "How?"

Li Dashou did not make his own comments, but looked at Wu Zhongyuan nervously, "Although this sword was beaten and cast by me, I have never held it to the point of being aware of it. Such divine objects are not allowed to be used by the Spiritual Saints. Please try it yourself."

"Don't care about these things," Wu Zhongyuan took action to disassemble the cloth bag. "You all work hard, I will give you my reward after you go back."

Li Dashou's eldest son was not good at speaking, and the second son Li said, "When this sword was released, golden light suddenly appeared, and strange images suddenly arise. My father prayed to sacrifice to heaven and earth, held the main hammer, and nine hits to calm the spirit. My brothers and two of them held the auxiliary, each of them dropped the edge and hammered thirty-six to consolidate the foundation, ninety-nine eighty-one hits, and the divine sword was formed, and the hilt of the sword produced yin and yang, and the sword body was concealed to hide the dragon soul, which was very magical."

Li Bing's words were both a reward and an introduction. Wu Zhongyuan was already excited. He could not control his heartbeat, took a deep breath, calmed himself, and slowly dismantled the cloth bag in his hand.

Li Dashou's long sword was not wrapped around, but folded in four directions. When he lifted the last piece of cloth, Wu Zhongyuan's mood was no longer described in words. He was both nervous and excited, just like the groom was about to pick up the veil of the bride who had never met on a wedding night.

Turning on the last cover, Wu Zhongyuan finally saw the long sword. This sword made him feel familiar. The reason for this feeling was that the long sword was made completely according to the size and shape he and Li Dashou had previously agreed. The long sword was not dazzling gold, but introverted yellow. Among the five shapes, yellow is earth, and the earth produces all things, which is the longest of the five elements.

While seeing the long sword, Wu Zhongyuan finally understood what Li Bing said about "self-generating Yin and Yang". There is a Tai Chi figure on the hilt of the long sword. The shape is not very regular, and it should not be artificially crafted.

"This is Yin, and the other side is Yang." Li Geng said.

Wu Zhongyuan looked up at Li and looked at him, reached out and held the sword. There was also a Tai Chi pattern on the hilt of the sword on the other side of the sword. Both are Tai Chi patterns, and it is easy to distinguish between Yin and Yang. The Tai Chi diagram on this side is Yang on the top and Yin on the bottom. The Yin side is Yin on the top and Yang on the bottom.

After holding the long sword, Wu Zhongyuan quickly noticed something strange. The temperature contrast between the front and back sides of the long sword was very large, the sun was very warm, and the shade was very cold.

"How could this be?" Wu Zhongyuan looked at Li Dashou in surprise.

Li Dashou was nervously waiting for Wu Zhongyuan to test his sword. When he saw him suddenly ask, he didn't understand why, and thought something was wrong, and his face changed drastically, "What's wrong?"

"One side of this sword is hot and the other side is chilling." Wu Zhongyuan said.

After hearing Wu Zhongyuan's words, Li Dashou and his son looked at each other. It was obvious that they did not know that the sword had such characteristics before.

After being stunned, Li Bing plucked up his courage to stretch out his fingers and attached the sword. He felt, "No."

Wu Zhongyuan reached out and pinched the sword's edge. There was indeed no temperature difference on the sword's body.

"You try the hilt of the sword." Wu Zhongyuan turned the long sword backwards and handed the hilt to Li.

Li Bing waved his hand in panic, "The magical weapon has spirit, and it is not necessary for the master to grasp..."

Before Li and finished speaking, Wu Zhongyuan stuffed the hilt of the sword into his hand, "You tried it, are you cold and hot?"

After obtaining Wu Zhongyuan's permission, Li Bing grabbed the hilt of the sword, held the front and the reverse, "It seems that there is some difference."

"What does it mean? The difference is very obvious." Wu Zhongyuan said.

Li didn't dare to hold it for a long time, and hurriedly handed the sword back to Wu Zhongyuan.

Wu Zhongyuan reached out to take it, and handed the sword to Li Bie with his backhand, "You try it."

Li Bie took it, and felt it, and nodded slowly, "It's true, the shade is cold and the sun is warm."

Wu Zhongyuan took the long sword back from Li Bie's hand to weigh and examine it. This long sword is very good in terms of length and weight. The hilt of the sword is also very good. The sharpness is not sharp, and you don't have to touch it with your hands. The hardness is not questioned, because according to the relevant theories of physics, the higher the melting point, the greater the hardness. As for the style, it is impeccable. It is clever and simple, without any unnecessary patterns. The weapons themselves are used to kill people, and it is meaningless to make some useless patterns.

The sword must be a good sword, but I don’t know what’s so magical. There is no difference in temperature in the sword body, and the cold and cold are only on both sides of the hilt. It must be a reason for this strangeness. As for what is going on, I have to try it out before I know it.

It's also very simple to try, just pour a little spiritual energy into it.

When the spiritual energy was poured in, the sword body suddenly changed color, from yellow to white, as white as jade, and there was white sword energy on the tip of the sword. Since there was not much spiritual energy infused, the sword energy did not extend much, but the faint sword energy made him feel familiar, as if he had seen something similar in shape somewhere.

He was puzzled and then some spiritual energy was urged to enter. The sword energy stretched out and the shape was prominent. It was a slowly moving dragon shape. On that day, he stole the oil oil from the ancestral grave of the Yi people. The flame of the oil lamp in the ancestral grave was in this shape.

The reason for this situation is that when the dragon oil is used to heat up the iron, the dragon aura in the dragon oil is mixed with the iron, so this kind of strange phenomenon appears.

However, although the sword body turned white, the temperature of the sword body did not change. What's going on?

Sometimes it may not be a good thing to understand too much. If you haven’t studied physics, Wu Zhongyuan will not have the habit of finding the root cause. He has been in college and always subconsciously tries to explain similar things with science, but he cannot explain it because there is no similar concept in physics.

After trying the front, Wu Zhongyuan changed to hold the hilt of the sword on the other side of the long sword and poured spiritual energy into it again. The color of the sword body changed again. This time it turned black. The entire sword body was as dark as ink, and the dragon-shaped sword energy was also black. The temperature was sensed, but it did not change.

Just as he was confused, Li Bie whispered from the side, "When you grasp the hilt of the sword, the Laogong acupoint in your palm just corresponds to the yin and yang on both sides of the hilt."

Wu Zhongyuan nodded. He had long discovered this. This sword is somewhat similar to a conversion device. The breath emitted when grasping the front of the sword hilt is the opposite of the breath emitted when grasping the back of the sword hilt. However, it is still unclear what the nature of these two breaths are.

There is no other way, I have to try it.

First, grasp the front, and do not cut down trees, just cut the stones, and the huge bluestone is cut off twice.

Hold the reverse side again and continue to slash, you can cut it off.

There seems to be no difference.

"Sir, urge the sword energy to try again." Li Dashou said.

It’s better to hold the sun first, stimulate the white dragon-shaped sword energy, and use the sword energy to cut the bluestone, and it will also be broken.

Holding the shade again, this time it was a black sword energy. The sword energy passed through the bluestone, but the bluestone did not break.

Everyone was a qi practitioner, and they were surprised to see this situation. The sword energy is an invisible and qualitative extension of the long sword. The effect of slashing with sword energy and slashing with sword body should be the same. Why does the black sword energy stop slashing with bluestones?

After pondering for a while, Wu Zhongyuan suddenly realized that breathing and breathing by the person who practices Qi gathers the spiritual energy that is free from heaven and earth. This long sword may have differentiated its spiritual energy into yin and yang energy and acted on external objects. When holding the hilt of the sword, the sword emits white yang energy. When holding the hilt of the sword, the sword emits black yin energy, the yang energy acts on the physical body, and the yin energy acts on the invisible soul.

Thinking of this, I was anxious to look around for living creatures, but the earth was shaking before, and all the people who could run away were running. There were no small animals nearby that could be used for experiments.

Hurrying to verify his guess, Wu Zhongyuan greeted Li Bie and others, then covered his stomach and rushed to the woods eastward. He knew the Aryan beast-seeking technique, and flew five miles away, quietly perceived, and soon found a living creature.

Seeing Wu Zhongyuan bringing back a mountain mouse that was squeaking, everyone was confused and looked at him.

Wu Zhongyuan didn't explain much. He pinched the mouse's tail with his left hand and held the sword in his right hand, urging the black sword energy to pass through the mouse's body. The mouse stopped moving, trembling, and still not moving, and was dead.

Needless to say, the facts are already in front of you. The front of the sword hilt is attached to the Laogong acupoint in the palm. At this time, the long sword belongs to Yang, which can destroy the physical body. The back of the sword hilt is attached to Laogong, which can destroy the spirit and soul.

Everyone was both surprised and happy, looking at Wu Zhongyuan. Wu Zhongyuan's mood was no longer described in words. He could not suppress the excitement and ecstasy in his heart. Due to excessive excitement, his whole body trembled involuntarily and could not even say anything.

In fact, it wasn't that he couldn't speak anymore, but that everyone couldn't understand, 'Oh, fuck me.'

If you have to compare, Wu Zhongyuan felt like he suddenly got a uranium bomb. Before that, he had been worried about how to resist gods, ghosts and demons. Now he is not worried. To be precise, he is not worried much. Even if the enemy has no entity, he can kill the other party. The reason why he is not worried much rather than completely worrying is that there is only one sword, which is a little too few.

"Congratulations," Li Qi took the lead in congratulating Wu Zhongyuan, "As soon as this sword is released, there will be no sword in the world since then."

"Happy together, happy together," Wu Zhongyuan bowed to Li Dashou and others one by one, "You will also leave your name forever."

Everyone was happy and humble.

Wu Zhongyuan said to Li Dashou again, "This sword is from the master's hand, so please give it a name."

"This is an usurpation, and it is impossible to use it," Li Dashou waved his hand in panic, "Please take it yourself,"

Wu Zhongyuan did not insist on it and said casually, "Well, then call it a long sword."

Everyone was surprised that he would give the sword such a name that was not like a name, but after savoring it, Li Dashou praised the name very much, "Length means long, long means long, the length of ten thousand swords, the king of swords."

As soon as Li Dashou interpreted, everyone suddenly realized that they admired Wu Zhongyuan for his admiration.

Wu Zhongyuan was admired so much that he felt guilty. In fact, he had no deep meaning. He was completely blind. If he really knew how to name a name, his mount and entourage would not be called Dasha or Huangmaoer.

The big thing came to an end, and there were still many trivial matters. There were still a few kilograms of golden meteorite left. Because Wu Zhongyuan had explained before, the remaining meteorite mixed bronze made a copper belt to put it on Dasha again. This thing is very important to Dasha. If there is no radiation from the meteorite, Dasha's lifespan will be affected.

In addition, Li Dashou and others also used amethyst to create many rings, which had to be made into an arrow pouch and inlaid on it.

Arrow pouches are easily worn, so there is no need to care about the material, just ordinary wood, just don’t use newly cut wood, as there is too much moisture and will deform after drying.
