The entire hall was already a sea of fire, Chen Nan and Chen Ying were rising and falling in the flames, and the sword qi was raging.

Chen Nan held Chixiao and Seven Star Dragon Yuan in both hands, surrounded by stars.

In the home field of the fire element, Chixiao itself has elemental bonuses, and a famous weapon with flame characteristics shines in this environment, directly pressing Chen Ying's Divine Sword to fight.

"You're still a little bit capable." Chen Ying snorted coldly.

The Sheshen Sword and the Heavenly Waterfall Sword were separated from his hands, and in order to know the Sea Imperial Sword, the scope of the battlefield was further expanded.

At the same time, nine lotus flowers condensed in front of him, and the crystal petals were like white jade.

Elemental Mystery: Nine Turns Lotus.

A B-class mystery composed of eight thousand runes, with a dangerous aura in the tranquility, firmly locked on Chen Nan.

"Hey, it looks like it's amazing."

Chen Nan sensed the power of these nine lotus flowers, but unfortunately he didn't have any elemental mysteries that he could get his hands on for the time being, after all, the points he earned were limited, and he hadn't exchanged them for elemental mysteries from the system for two days.

The first batch of recipes were of a relatively low level, and it doesn't have much effect when used now.

Then just cut off this lotus.

Chen Nan's mind moved, and the Seven Star Dragon Yuan, which had scattered around to interfere with the Heavenly Waterfall Sword, let out a crisp trilling sound, and the purple dragon at the hilt of the sword materialized and turned into the phantom of a giant dragon.

A low dragon groan echoed throughout the dueling arena.

Chen Nan knew the sea and the purple dragon, and maneuvered from the side to the route of Chen Ying's attack.

A pair of dragon eyes stared indifferently ahead, purple stars surrounded the dragon's body, and pale green flames were mixed with it, falling like a meteorite outside the sky, intercepting nine crystal clear lotus flowers.

This time there was no violent collision.

When the lotus flower encountered the purple star, it was directly shattered, and every fragment turned into an even smaller lotus flower.

The lotus turns nine times, and each turn recondenses into a new lotus.

A full eighty-one lotus flowers, along the route just now, rushed towards Chen Nan at an even more rapid speed.

"I was careless, I didn't flash."

Chen Nan didn't expect this lotus flower to be so changeable, and in a hurry, he could only use the purple dragon to resist.

Eighty-one white lotus flowers rushed into the illusory body of the purple dragon, releasing the energy of eight thousand runes from the inside.

The white flames burned through the illusory shadow of the purple dragon, and for a moment, the Seven Star Dragon Yuan Sword was riddled with holes.

The mysteries released by the evolutionaries are closely related to the star core, and Chen Nan, as the controller of the Seven Star Dragon Yuan, naturally has to bear the backlash caused by the destruction of this mystery.

A trace of crimson blood flowed from the corner of his mouth, and then quickly coagulated by the surrounding heat.

This variable brought a little trouble to Chen Nan, and Chen Ying, who was very good at seizing the opportunity, jumped continuously in the sea of fire, recalling the Heavenly Waterfall Sword to kill Chen Nan again.

A pair of cold eyes seemed to lower the temperature around him by a few points.

The qi of yin and yang was constantly changing in the Heavenly Waterfall Sword, and the Taiji diagram at the hilt of the sword turned into a gray disc, which was a blow that condensed Chen Ying's belief.

Boom!

A screeching sound of metal clashing sounded.

Chen Ying's mortal blow was blocked by a sudden sharp sword.

The sword is like a big sun, and the light reflects the mountains and rivers on the sword, and also reflects Chen Ying's somewhat stunned eyes.

The name is pure.

Chen Nan summoned a third divine weapon, which contained the heaviness of the earth, and completely blocked the Heavenly Waterfall Sword in front of him.

"You even summoned a sword."

Chen Ying gritted his teeth and retreated a few meters back.

"I can't think of it, I have a lot of treasures." Chen Nan stretched out his right hand and took the Chunjun hanging in mid-air.

This famous weapon with the same attributes as the Sheshen Sword, the sword is sealed with a small world, although Chen Nan's current ability cannot get a glimpse of the whole picture, but it does not prevent this heavy sword intent from pressing on Chen Ying's body.

Snort!

The sword pierced through the sea of fire.

Not far away, the Sword of God got rid of Chixiao's entanglement and came to Chen Ying's side again.

With two famous weapons by his side, Chen Ying's sword momentum reunited, turning into an invincible intent, hedged against Chunjun's sword intent.

Call!

The sea of fire was forcibly blown away by this thought, and it lost its subsequent elemental support, and most of it disappeared in an instant.

The entire hall on the negative seventeenth floor was restored to its original state.

I have to say that the scientific and technological power of the alliance is really amazing, even if the flame just now, it still hasn't changed here.

The ground was still pure white, but there were a few more sword marks on it.

"Chen Nan, you're a little interesting, it seems that I'm going to be more serious." Chen Ying stared at Chen Nan.

"If you can't fight, admit defeat early, why don't you take it seriously early, don't make these excuses, it's boring."

Chen Nan re-condensed the Seven Star Dragon Yuan, and at this moment there were three famous weapons hanging beside him, each sword carried a trace of divine forbidden power, allowing Zhihai to get a physical extension.

True Sword is well-informed.

With three famous weapons by his side, Chen Nan's sense of security finally returned.

"Do you think you're the only one with three famous weapons?" Chen Ying snorted coldly and closed his eyes.

A wave of air coalesced around him, and it seemed as if a wind was rising from the ground.

A faint elemental light lit up in front of him, converging into a third sword.

There was a groove in the slender blade, and the sound of a howling wind surrounded the blade.

Famous weapon: Mo Wen Sword.

Just when this famous artifact was fully formed, the Heavenly Waterfall Sword and the Sheshen Sword around Chen Ying seemed to have found a home.

The three famous weapons made a resonant sound, and the sharp sword roared louder and louder.

At the same time, pale yellow formation runes lit up at Chen Ying's feet.

Elements were constantly lit up in the void, and ancient symbols appeared in them, and finally turned into a large pale yellow array.

The large array with a diameter of five meters was a perfect equilateral triangle, with an arc of fire elemental at the outermost.

The three divine weapons each appeared at each vertex of the triangle, and Chen Ying was in the middle of the array, and with his thoughts, this formation rotated slightly.

This formation makes the compatibility between the elements and the sea of knowledge more complete, and if it can be maintained forever, Chen Ying definitely has the strength to fight against a thirteenth-level powerhouse.

"Your sword formation is a bit interesting," Chen Nan said, "I don't know what it's called?" ”

This sentence made Chen Ying a little irritable, and he said in a very tough tone: "You don't deserve to know his name." ”

On the grandstand on the minus fifteenth floor.

The old man looked at the two people in the audience with a smile on his face: "Little girl, do you know why Chen Ying didn't tell the name of the sword formation?" ”

Yang Dongbei thought slightly: "The names of the sword formations are all based on their characteristics, he doesn't want Chen Nan to deduce some characteristics of the sword formation based on the name." ”

"No, no, no," the old man laughed, "Chen Ying didn't want to say it, just because the name of this sword formation was not very domineering. ”

"Oh, then what is this not-so-domineering sword formation called?"

Yang Dongbei wanted to find out the name from the old man, and then find a way to give Chen Nan some hints.

"This sword array is called...... Triangular sword formation. ”

Yang Dongbei: "......"
