Li Dashou was shaking very much, not only his hands, but also his whole body, if he wasn't very excited, he wouldn't be like this.

Wu Zhongyuan was also very excited, but he didn't show it, and took the cloth bag with a smile, "How?"

Li Dashou didn't make a self-evaluation, but looked at Wu Zhongyuan nervously, "Although this sword was hammered and cast by me, I didn't hold it, and such a divine object cannot be used by the emperor unless it is a spirit saint, and I ask the adults to try it yourself." ”

"Don't worry about this," Wu Zhongyuan began to disassemble the cloth bag, "You have worked hard, I will have my own reward after I go back." ”

Li Dashou's eldest son is not good at words, and the second son Li He said, "This sword is golden when it comes out, the vision is born steeply, the father prays for heaven and earth, holds the main hammer, nine blows to fix the gods, my brothers and two are divided into auxiliary bi, each falling side hammer 36 records to solidify, 9981 hammers, the sword is completed, the hilt is born yin and yang, the sword body hides the dragon soul, and the magic is very." ”

Wu Zhongyuan was already excited, and when he heard Li Yan's words, his uncontrollable heartbeat accelerated, he breathed deeply, forced himself to calm down, and slowly dismantled the cloth bag in his hand.

Li Dashou's wrapping sword was not wrapped in a wrap, but folded in all directions, and when the final piece of cloth was uncovered, Wu Zhongyuan's mood could not be described in words, both nervous and excited, as if the groom was about to pick up the hijab of the bride he had never met on the wedding night.

Turning over the last cover, Wu Zhongyuan finally saw the long sword, this sword made him feel familiar, the reason why he had this feeling was because the long sword was completely in accordance with the size and shape agreed upon by him and Li Dashou, the long sword was not dazzling gold, but restrained yellow, among the five shapes, yellow is earth, and all things are born of earth, which is the length of the five elements.

At the same time as seeing the long sword, Wu Zhongyuan finally understood what Li Ji meant by 'self-generated yin and yang', there was a Taiji pattern on the hilt of the long sword, and the shape was not unconventional, and it was not artificially crafted.

"This is yin, and the other side is yang. Li said.

Wu Zhongyuan glanced up at Li Yan, stretched out his hand and held the long sword, there is also a Taiji pattern on the hilt on the other side of the long sword, the same Taiji pattern, it is also easy to distinguish yin and yang, the Taiji diagram here is yang on the top, yin on the bottom. On the yin side, the yin is on top and the yang is on the bottom.

After holding the long sword, Wu Zhongyuan quickly noticed something unusual, the temperature contrast between the front and back of the long sword was very large, the yang side was very warm, and the yin side was very cold.

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

Li Dashou was nervously waiting for Wu Zhongyuan to test the sword, and when he saw him suddenly asking, he didn't know why, thinking that something was wrong, and his face changed greatly, "What's wrong?"

"This sword is hot on one side and chills on the other. Wu Zhongyuan said.

Hearing Wu Zhongyuan's words, Li Dashou's father and son looked at each other, and it was obvious that they didn't know that the long sword had this characteristic before.

After being stunned, Li Ju had the courage to stretch out his two fingers, attached to the blade of the sword, and sensed the front and back, "No." ”

Wu Zhongyuan stretched out his hand and pinched the blade of the sword, and there was indeed no temperature difference on the sword.

"Test the hilt of your sword. Wu Zhongyuan reversed the long sword and handed the hilt to Li Yan.

Li Ji waved his hand in fear, "The gods have spirits, and they can't grasp the ...... if they are not the masters."

Before Li Ji finished speaking, Wu Zhongyuan stuffed the hilt of the sword into his hand, "Have you tried, is it cold and hot at the same time?"

With Wu Zhongyuan's permission, Li Ji grabbed the hilt of the sword, held the front and then the back, "It seems that there are some differences." ”

"What do you mean, the difference is very obvious. Wu Zhongyuan said.

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

Wu Zhongyuan stretched out his hand to take it, and handed the long sword to Li Bei with his backhand, "You try." ”

Li Bei took it, sensed the positive and negative, and nodded slowly, "That's true, the yin side is cold, and the yang side is warm." ”

Wu Zhongyuan took back the long sword from Li Bei's hand and weighed it, this long sword is very good in terms of length and weight, and the grip of the hilt is also very good, the edge is not sharp and you don't need to touch it, you can see it with the naked eye. There is no need to question the hardness, 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 clumsy, the road is simple, there is no superfluous ornamentation, the weapon itself is used to kill, and it is pointless to engage in some useless ornamentation.

The sword must be a good sword, but I don't know what is strange, there is no difference in temperature between the sword body, the cold and heat are only on both sides of the hilt, so strange, there must be a reason, as for what is going on, you have to try it to know.

The trial is also very simple, directly poured a little aura.

The aura was poured in, and the sword body suddenly changed color, from yellow to white, white as jade, and there was white sword qi at the tip of the sword, because there was not much aura infused, the sword qi did not extend for much time, but the looming sword qi made him feel familiar, as if he had seen something similar in shape somewhere.

Doubts in his heart, and urged some aura, the sword qi elongated, the shape was prominent, it was a slow-moving dragon shape, that day he stole Jiao oil from the ancestral tomb of Yiren, and the flame of the oil lamp in the ancestral tomb of Yiren was in this shape.

The reason for this situation must be that the dragon breath in the Jiao oil was mixed with the molten iron when the Jiao oil was used to heat up the meteoric iron, so this anomaly appeared.

However, although the sword body has turned white, the temperature of the sword body has not changed, what is going on.

Sometimes it is not necessarily a good thing to know more, if you have not studied physics, Wu Zhongyuan will not have the habit of finding the bottom of it, he is a person who has gone to college, and when he encounters similar things, he always subconsciously tries to explain them with science, but he can't explain them, because there is no similar concept in physics.

After trying the front, Wu Zhongyuan changed his grip to the hilt on the other side of the long sword, and poured the aura again, and the color of the sword body changed again, this time it became black, the entire sword body was as black as ink, and the dragon-shaped sword qi was also black, and the sensing temperature did not change.

Just wondering to himself, Li Beizi whispered from the side, "When you grasp the hilt of the sword, the Lao Gong acupoint in the palm of your hand happens to correspond to the yin and yang on both sides of the hilt. ”

Wu Zhongyuan nodded, he had already discovered this, this sword was somewhat similar to a conversion device, and the breath emitted when grasping the front of the sword hilt was the opposite of the aura emitted when grasping the reverse side of the sword hilt, but it was still unclear what the nature of these two breaths was.

There's no other way, you have to try.

Grasp the front first, do not cut the tree, directly cut the stone, the huge bluestone is cut in two.

If you hold the opposite side again, continue to slash, and you can also cut it.

It doesn't seem to make a difference.

"My lord, urge the sword qi to try again. Li Dashou said.

Or hold the yang side first, provoke a white dragon-shaped sword qi, and slash the bluestone with the sword qi, and also break.

Hold the yin side again, this time it is a black sword qi, the sword qi crosses the bluestone, and the bluestone is not broken.

Everyone is a person who practices qi, and they are all surprised to see this situation, the sword qi is an invisible and qualitative extension of the long sword, and the effect of slashing with sword qi and slashing with the sword body should be the same, why does the black sword qi chop the bluestone?

After pondering for a moment, Wu Zhongyuan suddenly realized that the breath of a person who practices qi is to gather the aura that is free between heaven and earth to gather itself, and this long sword is likely to divide its own aura into yin and yang qi and act on foreign objects, holding the hilt of the sword, the long sword emits white yang qi. Holding the hilt of the sword, the long sword emits black yin energy, yang energy acts on the physical body, and yin energy acts on the invisible soul.

Thinking of this, I hurriedly looked around for living creatures, but the ground that had been beaten before shook the mountains, and all those who could run ran away, and there were no small animals nearby that could be used for experiments.

Eager to verify his guess, Wu Zhongyuan said hello to Li Bei and the others, and then covered his stomach and swept towards the woods to the east.

Seeing that Wu Zhongyuan came back with a squeaky mountain mouse, everyone didn't know why and looked at him suspiciously.

Wu Zhongyuan didn't explain much, pinching the tail of the mouse in his left hand, holding the sword in his right hand, urging the black sword qi to cross the mouse's body, the mouse didn't move, trembled, still didn't move, and died.

Needless to say, the facts are already in front of you, the front of the sword hilt is attached to the palm of the Lao Gong acupoint, at this time the long sword belongs to the yang, which can destroy the physical body. The reverse side of the hilt of the sword is attached to the Lao Palace, and the long sword is yin, which can destroy the soul of the soul.

Everyone was surprised and delighted, and looked at Wu Zhongyuan, Wu Zhongyuan's mood at this time could not be described in words, and he couldn't hold back the excitement and ecstasy in his heart.

It's not that he can't speak, it's that people don't understand, 'Oops, fuck me.'" ’

If you have to make an analogy, Wu Zhongyuan's mood at this time is like suddenly getting a uranium bomb, before this he had been worried about how to resist gods and demons, but now he is not worried, to be exact, he is not so worried, even if the enemy has no entity, he can kill the other party, the reason why he is not worried so much is not completely worried, because the long sword only has this one, a little less.

"Congratulations, my lord," Li Yan took the lead in congratulating Wu Zhongyuan, "This sword has been released, and there has been no sword in the world since then." ”

"Tongxi, Tongxi," Wu Zhongyuan Chong Li Dashou and others surrendered their hands one by one, "You will also leave your name through the ages." ”

The hearts of the people rejoiced, and their mouths were humble.

Wu Zhongyuan said to Li Dashou again, "This sword is from the master's hand, and I also ask the master to give it a name." ”

"This is trespassing, I can't help it, I can't do it," Li Dashou waved his hand in fear, "Please take it yourself,"

Wu Zhongyuan didn't blindly insist, and said casually, "Okay, then call it a long sword." ”

Everyone didn't expect him to give the sword such a name that didn't look like a name, and they were all surprised, but after tasting it, Li Dashou praised the name, "Long is long, long is long, the long of ten thousand swords, the king of swords." ”

As soon as Li Dashou interpreted, everyone suddenly realized, and there were many praises for Wu Zhongyuan's admiration for the five-body casting.

Wu Zhongyuan is admired for his good heart, in fact, he has no deep meaning, he is completely blind, if he really knows how to name it, the mount and the servant will not be called Dasha and Huang Maoer.

The big thing is over, there are still many trivial matters, there are still a few catties of golden meteorite left, because Wu Zhongyuan has explained before, the remaining meteorite mixed bronze to create a copper belt, and put it on Dasha again, this thing is very important to Dasha, if there is no radiation of meteoric iron, Dasha's life will be affected.

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

The quiver is a wearing part, there is no need to care about the material, just ordinary wood, just don't use freshly cut wood, too much moisture, it will be deformed after drying.

After Chong Li Dashou and others dictated the size and size of the quiver, Wu Zhongyuan began to study the long sword in his hand, which was his own saber, and he had to understand all its various characteristics......
