Although it was the punch he used in the mechanical armor just now, Hua Yan's arm still received some power backlash, and his arm and fist cracked a lot, but the injury was still lighter than the one he had suffered when he used it before.

After the battle, Hua Yan hurried to repair his wounds, while looking at Shi Feng, and found that he had an inscrutable temperament, his demeanor was graceful, and he had the smell of fireworks that did not eat the world.

After Shi Feng confirmed the death of the dragon scale demon pig, he ordered the three people next to him to clean up and bury the corpse of the one named "Ah Li" who unfortunately died in battle just now, Hua Yan looked at the three of them with indifferent expressions, obviously they were used to seeing this kind of thing.

Then Shi Feng got up and arched his hand to Hua Yan and said.

"Brother Huayan, thank you for your help!"

"You don't have to be so polite~"

Hua Yan, who had repaired the injury on his arm at this time, took off the helmet of the mechanical armor, waved his hand slightly, and said.

"Brother Hua Yan also took the task in the Steel City to hunt demon beasts?"

"It's really admirable to be able to break into this demon beast forest alone!"

Shi Feng looked at Hua Yan and said with admiration.

"No... No..., I had just arrived from out of town, and I was about to go to the City of Steel, and I happened to pass by. ”

Hua Yan said lightly, and at this time, his attention had been on the bronze ancient sword in Shi Feng's hand, and he was using his perception to probe, and found that this bronze ancient sword was indeed extraordinary.

He found that this bronze ancient sword contained two runes, and the lines seemed to be the ancient seal character "Kun" composed of gold, which immediately confirmed Hua Yan's previous guess.

This rune really has something to do with the I Ching gossip!

Now what Hua Yan wants most is to study this bronze ancient sword well, if only he could borrow it for a few days, Hua Yan thought to himself.

"Although this dragon scale demon pig was killed by the two of us together, and the credit of the Hua Yan brothers should account for most of it, I don't know what you are going to do with the corpse of this dragon scale demon pig?"

Shi Feng saw that Hua Yan was a little absent-minded at this moment, so he smiled and pointed to the corpse of the dragon scale demon pig and asked.

In fact, he was also shocked in his heart now, he couldn't imagine that Hua Yan was wandering alone in this demon beast forest, he was very clear about the danger here, the strength that Hua Yan showed just now was obviously higher than him, thinking of this, he looked at Hua Yan with a much more solemn expression, and even had the intention ......of making friends.

"This corpse doesn't matter, if you need it, just take it~"

Hua Yan had been using his perception to detect the ancient sword, and he was hurrying to trace the "Kun" character in his mind, but he couldn't care about the corpse of the demon beast.

In fact, Hua Yan also used his perception to detect Shi Feng just now, and found that he was somewhat similar to Murong Xuan, and he also had a rune in his head, but this rune was an ancient seal "wind" word, and two runes were found at the same time, which made Hua Yan ecstatic in his heart~

It's just that now he attaches more importance to the "Kun" character text on the ancient sword, and the matter of the "wind" character text can only be postponed first, and now Hua Yan wants to have a good relationship with Shi Feng first, and then find a way to trace the "wind" character text in the future.

"I'll tell you the truth, I took over the family mission from the Steel City this time, mainly to hunt demon beasts, and then hand them over to the city for research, the reward for this task is extremely high, and the skin of this dragon scale demon pig is an excellent armor material, Brother Hua Yan can't miss the treasure so casually~"

Seeing that Hua Yan didn't take the precious corpse of the dragon scale demon pig to heart, he admired Hua Yan's arrogance even more, and his heart was even stronger, so he hurriedly explained the benefits to Hua Yan.

"That's it~"

Hua Yan also came back to his senses a little at this time, but he had an idea.

"I'll give you all the corpses of this dragon-scale demon pig, but... I want to borrow your bronze ancient sword to study for two days, I don't know if it's okay? ”

Hua Yan scratched his head and said a little casually.

Hearing Hua Yan say this, Shi Feng was taken aback in his heart, the bronze ancient sword was the foundation of their family, and he didn't know many secrets, he just used it according to the guidance of his predecessors, could this young man be able to discover what secrets were inside?

After this young man knew the huge value of this dragon scale demon pig, he still gave it to himself happily, but he only asked to borrow the ancient sword for two days, it stands to reason, he should not refuse, but this matter is not something he can decide.

"Brother Huayan, I really shouldn't refuse this matter, it's just that this bronze ancient sword is a family thing, and I have to hand it over immediately after I return to the Steel City~"

Shi Feng looked embarrassed and said with a somewhat embarrassed smile.

"Oh?"

"Then let's get out of this demon beast forest first, stay overnight outside the city first, and then go back tomorrow, how about it?" I'll borrow it for one night, and tomorrow you will go back with the bronze ancient sword and the corpse of the dragon-scale demon pig! ”

Hua Yan was stunned for a moment, but he didn't hesitate, and said.

"Good!"

Shi Feng's eyes lit up, and he readily agreed to Hua Yan's proposal, but he was a little embarrassed to take too much advantage, so he said:

"That's it! It's just that the skin of this dragon scale demon pig is too precious, and when I finish the task, the skin of this dragon scale demon pig will be peeled off, and the two of us will be half! ”

"Alright then!"

Hua Yan walked towards Shi Feng, then stretched out a hand, and then the two of them slapped their hands tacitly, and laughed at the same time!

Later, after they left the Demon Beast Forest, they walked more than ten kilometers in the direction of the Steel City, then found a clearing place, lit a bonfire, and set up camp in the wild.

The corpse of the dragon scale demon pig weighed two tons, but the three people led by Shi Feng didn't seem to have much trouble carrying it, Hua Yan couldn't help but nod secretly, it seems that these Shi Feng's entourages are not weak hands.

"Let's rest here tonight, you can rest assured to study, I'll be a sentry~"

Shi Feng walked up to Hua Yan, handed him the bronze ancient sword, and then said with a smile.

"Good!"

Hua Yan took the bronze ancient sword, did not hesitate, immediately sat down cross-legged, held the bronze ancient sword in both hands and put it on his lap, and used his perception to sink his consciousness deeply into the bronze ancient sword......

The bronze ancient sword is composed of gold silk threads to form two "Kun" character characters, one rune contains soul energy, and the other rune contains heat energy and some radioactive energy.

The terrain is kun, and the gentleman carries things with virtue!

What the Book of Changes said is true, the main function of this "Kun" character is storage, the wisdom of the ancient ancestors is really infinite, the human body can not carry too much soul energy, and it can even think of using foreign objects to store, Hua Yan couldn't help but sigh in his heart!

Combined with the images of the ancient Chinese people in his mind, Hua Yan soon deduced the general situation of the ancients' use of soul energy.

The first step of the Gu Huayan people is to use the soul energy to warm the gold, gold is the best conductor of soul energy outside the human body, after more than ten years of warmth, the soul energy conductivity of these gold has been improved to excellent, and the gold at this time is also called - soul gold!

Then the swordsmith embedded these soul gold into the bronze, and then began to build the bronze ancient sword, in the process of building, they kept beating with a hammer, so that the soul gold was constructed into two "kun" characters in the bronze ancient sword, and then one rune stored soul energy, and the other rune stored material energy (including heat energy, radioactive energy, etc.).

The "Kun" character is a special rune, and after the engraving is completed, it only needs to be infused with three strands of material energy, and there is no need to infuse soul energy.

After the two "Kun" characters are formed, this sword is completed, and with the blessing of the "Kun" characters, the toughness of the sword will be doubled, and it will eventually become a generation of famous swords!

And the first thing that the ancient soul energy who obtained these swords had to do was to use these ancient swords to store soul energy and material energy.

The storage of soul energy depends on the soul energy person to raise the sword first, and it takes ten years to raise the sword, and then the soul energy is slowly transmitted from the soul energy to the "Kun" character text and stored it, while the storage of material energy is simpler, you only need to put the bronze ancient sword in the furnace and heat it repeatedly!

The ancient Chinese soul energy did not have a divine palace like Hua Yan to divide soul energy and material energy in two, and actually used two Kun characters to divide yin and yang, which is really a genius idea!

After the soul energy and material energy stored in the two runes in the bronze ancient sword reach a certain level, you can start to use the soul energy and material energy in these bronze ancient swords to construct runes in the body.

Hua Yan couldn't help but be amazed by the genius practices of these ancient Chinese people, but at the same time, Hua Yan had a doubt, how did these soul gold forge two "Kun" characters in the bronze ancient sword.

It is basically impossible to rely on external forces to beat it alone, and this difficulty is no less than writing a novel with a face rolling keyboard, could it be that these swordsmiths also have a certain sense of perception? It is no wonder that ancient swordsmiths were so rare, and the status of a swordsmith was even higher than that of the princes and kings at that time.

Most of the runes that the ancients first chose to construct were "Ze" characters, because this rune can repair the damage of the human body and greatly improve the lifespan of human beings.

And it takes a long time to raise a sword, build a rune, and warm the soul gold, which requires enough life to support, even so, many people can only build one rune in their lifetime, and the priority to choose the "Ze" character text construction has also become the most popular option for the soul of the ancient Chinese people.

After figuring out these things, Hua Yan began to construct the "Kun" character script in his brain, and at present, the soul energy and radioactive energy stored in the Divine Palace in Hua Yan's brain are sufficient, so Hua Yan can directly construct the "Kun" character script.

Hua Yan first used his consciousness to construct a "Kun" character in his brain, and then three black radioactive energies came out of the Divine Palace and entered the "Kun" character, and as the energy operated, the word "Kun" became more and more vivid.

Hua Yan repeatedly adjusted the runes in the bronze ancient sword, simulating the energy flow route, until the second half of the night, and finally successfully constructed the "Kun" character in his brain!

After doing these things, Hua Yan breathed a long sigh of relief, in the future, he could also cast a large number of these swords for Xiao Li to use, and then he would have the opportunity to help them build runes, which would greatly improve the strength of the soul powerhouses in the entire Hope Town.

Thinking of this, Hua Yan couldn't help but look up to the sky and let out a long roar, the secret of the ancient sword that he had been pursuing for so long had finally been solved, and the harvest really lived up to his ......expectations.
