In the whirlpool at the bottom of the endless abyss, a dark cyclone suddenly appeared.

The cyclone is spinning wildly, and if you look closely, you can also find that there are two yin and yang eyes in the center, one black and one white symbolizing yin and yang Taiji, which is similar to the black hole in the cosmic starry sky as a whole.

This is Tang Feng's Dao Platform, Devouring Dao Platform!

As soon as the Devouring Dao Platform came out, it immediately burst out with a violent devouring force, and the sword qi that had originally rushed over was devoured into it.

"Refining!" Tang Feng roared, after devouring most of the sword qi, his pressure was reduced a lot, and what surprised him even more was that after refining, all of these sword qi were transformed into pure energy.

"This is a great supplement!" Tang Feng's heart moved, absorbing under the heavy pressure like a mountain, and his aura was rising at this moment.

However, in the blink of an eye, he had broken through from the original Daotai Fivefold Realm to the Sixfold Realm.

"Come again, no matter how much sword qi there is, in short, you can swallow as much as you want!" At this moment, Tang Feng's whole person was like a whale swallowing water, and all the countless surging sword qi was swallowed.

His aura was still rising, that is, more than a dozen breaths, and the realm rose again, breaking through to the Daotai Sevenfold Realm!

"It is worthy of being the treasure of the Great Sect, could it be that the sword qi of this Haotian Knife is endless?" Tang Feng was suspicious in his heart, if it continued like this, he was afraid that this Haotian Knife would most likely become a waste knife.

However, at this moment, the sword qi rushing up from below suddenly stopped, and the pressure also decreased.

"Actually stopped?" Tang Feng smacked his lips a little unsatisfied, but since the pressure had been reduced, this was also a good thing, and his body sank at the moment, and soon reached the bottom.

In the depths of the lake, there was a stone chamber about ten square meters, which was irregular, with eight edges and corners, each of which protruded a thick chain of adults.

The eight chains were densely engraved with countless formation runes, and a jet-golden broadsword was firmly locked at the bottom.

Thinking about it, this black golden big knife should be the legendary Haotian Sect's treasure Haotian Knife.

Tang Feng did not rush in, and through observation, he also found that there were four thick turtle feet under the Haotian Knife, which blocked it.

"I really can't imagine that just sealing this Haotian Knife actually used two large arrays, and even used the turtle feet of the first generation of divine turtles as an array to suppress it!" Tang Feng secretly stuck out his tongue.

The stone room at the bottom, on the contrary, was calm, Tang Feng did not feel any compelling momentum, and after repeated observations, he determined that there was no danger, and then he stepped in.

Although he had entered the sealing place now, Tang Feng was in trouble for a while.

"This sect sealing array, although it can be forcibly broken with strength, but once it is broken, it is only a troublesome matter to subdue this Haotian Sword. Tang Feng shook his head secretly.

As early as when he was in the ancestral land of the earth, Tang Feng had already seen it, and at this level, he had basically produced spiritual intelligence, maybe the wisdom of the sword spirit was not high, and it could not reach the point where he could speak on his own, but the spiritual wisdom was definitely not low.

For example, the Zhentian Bowl of the Ten Thousand Buddha Sect obtained by the wild dragon, at that time, everyone basically couldn't surrender it, and in the end, the Zhentian Bowl was dominated by the spirit of its own mad dragon, otherwise I am afraid that it would have escaped.

"There is another problem, once the suppression seal is broken, the sect will naturally know about it, and I am afraid that the Haotian sect will also have a sense of it, and even use a secret method to recruit it back."

Tang Feng frowned tightly and said in a deep voice: "Therefore, we must think of a foolproof strategy, after breaking the seal, subdue this Haotian Sword as quickly as possible!"

There is no water in the stone room, the aura here is too strong, the pressure is too great, and even the water above the bottom of the lake cannot be poured in, Tang Feng walked step by step along the Haotian Knife, thinking about countermeasures in his heart.

"There it is!" Tang Feng's eyes suddenly lit up, and he thought of an excellent solution.

"Since this Haotian Sword already contains spiritual wisdom, then I may be able to cast the Fifth Realm Secret Technique of the Great Yan Star Technique on it!" Tang Feng's whole person became a little excited.

On the surface, this seems a bit incredible, but theoretically it can work, because this method of detaining the gods is useless for mortals, but it has an effect on the spiritual soul.

"As long as you detain the sword spirit, I'm afraid that it will run out of the palm of your hand!" Tang Feng laughed.

However, for the sake of safety, he still sacrificed his devouring Dao platform again, and with a wave of his big hand, the Dao platform reached the top of the Haotian Knife, which was to prevent the other party from escaping at the first time.

Immediately afterwards, he took out a piece of rune paper from the storage ring, and after a specific secret method was cast, it was directly attached to the body of the Haotian Knife.

After doing all this, Tang Feng retreated slightly, and the next step was to break the seal.

"The sword is coming!" Tang Feng beckoned, and suddenly a rainbow light flashed in the stone room, and the turtle immortal sword was condensed.

"Slash!" Tang Feng exhaled, and the Turtle Immortal Sword suspended above erupted with a dazzling light, sweeping like a comet.

In an instant, the entire stone chamber erupted with a loud bang and shook non-stop, and even the lake above set off a stormy wave, and the entire Xuanwu Sect was alarmed, and many people in retreat were disturbed, and even the timid people thought it was an earthquake.

The stone chamber gradually calmed down, to Tang Feng's surprise, the chain was not broken by a sword, after all, the Turtle Immortal Sword was a secret method condensation, not an entity, and it lacked power in power.

"There's something about this chain, it can even block my sword, if you take it out to the refiner, it is estimated that it will be able to refine a good magic weapon." Tang Feng said with a smile.

Although the chain has not been broken, it has been cut out of a gap, and Tang Feng understood a truth at a very young age, if the things in the world are not successful once, then twice, and if they fail twice, then three or four times......

"The sword is coming!" Tang Feng beckoned, and the Turtle Immortal Sword appeared out of thin air again, and a sword fell, and the entire sect once again erupted with a loud rumbling sound.

"Come again!" Tang Feng drank coldly, anyway, his dantian spirit yuan was incomparably majestic, if it was an ordinary martial artist, he couldn't afford such a consumption at all.

And just when Tang Feng broke the seal again and again at the bottom of the lake, the two elders of the Turtle Valley Hall were not calm, they were guardians after all, where could they still sit still after the successive vibrations.

"What the hell is going on? Is it Tang Feng's kid who made it, what the hell is he doing?"

"No, hurry up and take a look, if it goes on like this, I'm afraid the Turtle Valley will collapse!"

The two elders said that they were about to rush in, but at this moment, two people suddenly appeared out of thin air in the main hall, it was the sect master Liu Tianxin and the turtle Yan peak master.

"You guys stop first!" Liu Tianxin called the two elders in time.
