The sword is born from the heart.

Chen Nan finally understood what sword intent was.

Every mystery that can become a famous weapon is actually the sword-wielder's perception of heaven and earth, so as to turn a certain vision of heaven and earth into his own use.

With the sword as the pen, every grass and tree, every mountain and water in this world can be painted.

The spirit of heaven and earth condenses into an immortal picture, there is an immortal scene in this painting, and the depiction of each scene is the power of ten thousand jun, and at the same time, it can also be used to walk the dragon and snake, as light as a feather.

Each kind of strength is a different sword intent.

Chen Nan was in Ye Xun's small world, and after seeing the magnificent scene of the Heavenly Waterfall Sword, Zhihai was touched in a certain way.

So he summoned a square sword formation.

Chunjun with its own projection of mountains and rivers, the seven-star dragon abyss that turns into stars, the red sky with the spine of the big dragon, and the fish intestine sword with patterns stacked like a clear spring.

Four famous weapons containing the origin attributes of heaven and earth were suspended around Chen Nan in this way.

He closed his eyes and slowly lifted his palm.

The first was Chun Jun, who had the meaning of the earth's heaviness, and the wide sword body slowly fell on Chen Nan's hand.

With a slight touch, the sword was like a great sun, releasing a dazzling light, reflecting the mountains and rivers on the sword, and at this moment, the pure Jun sword seemed to come to life.

Chen Nan had an understanding, and the scene sealed on the sword body was the picture of the sword intent that the sage Zhao Dongliang comprehended when he created the Pure Jun Sword.

His hands pierced through the illusion, and his body seemed to enter the pure mountains and rivers.

However, Chen Nan has not mastered the real famous weapon now.

With a few thousand runes alone, it was difficult to project the real mountains and rivers, so Chen Nan's hands passed through the phantom.

But Chen Nan didn't show any signs of frustration.

The corners of his mouth curled slightly, as if confirmed.

Then he controlled the other three famous weapons one after another, and each of them had a concrete picture.

This is the origin of the sword.

When Chen Nan can reproduce these pictures completely, he can truly release the power of the famous weapon.

If he could expand the picture outward, he could even further refine the name.

This is only theoretically achievable, after all, it is a mystery left by the sage, and it is really too difficult to further improve it.

"The four elements of earth, water, fire, and wind, through different permutations and combinations, constitute a vast mystical method." Chen Nan had a feeling in his heart, "And the famous artifacts are the purer energies in the mysteries, they are outlined by a single element close to the origin. ”

In a square sword formation.

The four handles can transform each other's characteristics through resonance.

This transformation is only borrowing, not fusion.

If you want to make the power of the square sword formation even more powerful, you must increase the duration of this resonance, so that the characteristics of the famous weapons can be borrowed from each other for a long time.

Like this......

Under Chen Nan's conscious control, the sea of stars sealed in the Seven Star Dragon Yuan Sword continued to fade, and then slowly merged with the mountains and rivers in the Pure Jun.

Chunjun's sword was no longer dazzling, and the great sun was extinguished, replaced by a purple star.

In that small world, time and space suddenly changed, and a bright night sky enveloped the mountains and the earth, and the beasts disappeared, and everything was silent.

Only the night breeze blew through the ridges, and the light of the stars shone over this slightly lonely world.

The properties of the earth element, and the characteristics of the wind element, at this moment there is a wonderful chemical reaction here, forming this harmonious picture.

Chen Nan carefully controlled the sword formation, and slowly approached Chixiao's vision to this small world.

One of the mountains shook violently and turned into a restless volcano, and raging magma erupted and shattered the silence.

Wow~

A large river rushes from the mountains, and countless silverfish jump in the river, making the world richer.

In the sword array centered on Chen Nan, there are four layers of space in a clear layer, which is the projection of the sword intent of each of the four famous weapons, and with the blessing of the sword array, they are organically combined together.

It makes up a picture like this.

It's a pity that Chen Nan's level is not enough now, and he can't build a clearer and more realistic picture.

"Click~"

The sound of a shattered mirror sounded.

The realm within the realm constructed by Chen Nan was finally unable to be maintained, and it was shattered into fragmented pieces.

"Senior brother, I didn't expect that you are only level 12, and you have already preliminarily comprehended the true meaning of famous weapons." Ye Xun said with a smile, "Congratulations, now your comprehension of the sword formation has gone further. ”

Chen Nan breathed a long sigh of relief.

It seems that this time he didn't come in vain, and with the help of Senior Brother Ye, his comprehension of the sword array reached version 2.0.

If a few hours ago, Chen Nan had only initially entered the sword formation under the pressure of Chen Ying, but now his comprehension of the sword formation has reached the level of entering the room.

Coupled with the blessing of the four famous weapons themselves, Chen Nan felt that he now had the strength to leapfrog the challenge.

"Thank you Senior Brother for your guidance," Chen Nan said sincerely, "Sure enough, the stone of the mountain can attack jade, and I am more sure of breaking through the thirteenth level." ”

"I know that Chen Nan is the most powerful." Yang Dongbei smiled on the side, happier than he understood.

"Xiaobei is right, you are talented, if you don't have talent, even if I stuff the famous weapon into his body, I won't be able to see through the truth."

Ye Xun's eyes were full of approval.

"The biggest gain this time is actually to recognize Senior Brother Ye, and the younger brother will also have a mentor in the future." Chen Nan said with a smile, "If you go out for a walk like this, you will be less beaten." ”

"Hmph, whoever dares to beat you, I'll go and take his whole family." Ye Xun pretended to be serious.

"Senior brother is awesome."

"Protect the best Senior Brother Ye."

Chen Nan and Yang Dongbei gave a thumbs up together and praised Ye Xun.

"Okay, since you're leaving, I won't stay longer, and I'll go to the Alliance headquarters in a few days to report on my work, and we should be able to meet there."

Ye Xun dispersed the illusion, and they returned to the practice room.

There were several majestic sword qi around, which were the marks left by the Heavenly Waterfall Sword through the "realm" in reality.

With hundreds of thousands of rune condensed famous weapons, even Ye Xun could not completely control them in the small world.

"Senior Brother Ye, let's go back the same way, and ask Senior Brother to help provide permission." Chen Nan said.

His artificial skin has been damaged and now has no proper identity to go out.

"Don't be so troublesome," Ye Xun led the way in front, "There are other passages to the base to go outside." ”

"It just so happens that I'm in the base, and I can open a secret passage for you, where you don't have to go through the three major areas, you can directly lead to the river on the ground, and the scenery along the way is very beautiful."

Ye Xun walked in front and led the way for the two.

"I didn't expect there to be such a sightseeing route...... Chen Nan sighed, "Then thank you brother." ”

This secret passage was definitely built by Ye Xun himself, because Chen Nan's original drawings did not have this road.

Yang Dongbei followed quickly, and the three of them came to the innermost laboratory.

Under Ye Xun's control, the walls of the laboratory opened to both sides, revealing a secret passage that could accommodate two people together.

Inside the passage there is good gout, and there is also a power supply system working.

"Thank you, senior brother, then we'll see you at the headquarters."

Chen Nan and Yang Dongbei stood at the entrance of the passage and said goodbye to Ye Xun cordially.

Meanwhile.

Blue Blood Lab in Ward 2, in the restroom.

Our Youdao classmates are still staying with two unconscious researchers.

He held two boxes firmly, the trophies he and Nange had gotten from Old Jack.

Next to him were the unconscious Professor Barrett and Assistant Auston, the android who thought he was Chen Nan, who was sleeping on the test bench outside the bathroom.

Now it has been a long time since he was separated from Chen Nanyang in the northeast, and the professor even woke up once in the middle and was fainted again by His Highness Youdao, but it is definitely not a way to continue like this.

"Sister, Brother Nan, why haven't you come yet......"

Mu Youdao stayed in the corner of the bathroom with the box in his arms.

Weak, pitiful, and helpless.
