The rolling black qi invaded the sea of knowledge, Lu Chen gritted his teeth and confronted the black qi, and he had no time to explain to Gu Linglong everything that had just happened.

Seeing that Lu Chen never responded, Gu Linglong hurriedly swam out of Lu Chen's sleeve, and looked at Lu Chen, Gu Linglong was slightly stunned, and then said angrily: "It's all your crow's mouth!" I said that there must be treasures in the underground ban, you have to say that there are not necessarily treasures in the underground ban, now it's okay." And the first-generation master of this Red Fire Gate must be a person who is yin and immoral, and he can't hide treasures from the underground seal, but he uses it to block evil thoughts, it's really sick!"

At this moment, Lu Chen had already fallen into the confrontation with the billowing black qi, and he couldn't hear Gu Linglong's complaining words at all. When the wisp of sea knowledge that went deep into the underground ban was swept away, Lu Chen withdrew the power of sea knowledge back to know the sea, intending to close the sea knowledge dragon gate immediately. How could it be that the black qi in the underground ban was calculated or not, Lu Chen was a step slower after all, and was invaded by the black qi into the sea of knowledge.

I saw a huge black gas volley floating in the sky over the sea of consciousness in a square circle, like a black cloud, although Lu Chen didn't know what this black cloud was, but he could keenly perceive that if this black cloud was always entrenched in his sea of knowledge, the end would be very miserable!

Realizing this, Lu Chen used the power of the sea to drive the black cloud out of his sea of knowledge, but the black cloud did not move at all.

Not only that, while Lu Chen drove away the black clouds, although the black clouds were motionless, they were changing violently inside. The black clouds were like boiling, and the black gas in the clouds was surging, and suddenly hundreds of black lines shot out from under the black clouds, like black arrows shooting towards Lu Chen's sea of knowledge.

Seeing this, Lu Chen's heart was awe-inspiring, and the sea of knowledge that was square and square turned into a whole piece of incomparably hard black iron in an instant. The moment the sea of knowledge turned into dark iron, the black qi arrows also shot out.

Aggressive...... The black gas arrows collided violently with the Xuantie Zhihai, and sparks sputtered out, roaring in the Zhihai. As soon as they clashed, hundreds of fist-sized pits appeared in Lu Chen's Xuantie Consciousness Sea, all of which were bombarded by black qi arrows! Seeing this, a touch of surprise flashed in Lu Chen's eyes, if he hadn't used the power of the ban to condense his knowledge of the sea once before, with the confrontation just now, he would have suffered a big loss under the attack of a wave of black qi arrows sent out by the black clouds.

And at this moment, Gu Linglong cast a secret method, and her voice came into the depths of Lu Chen's soul: "This black cloud is the evil thoughts of knowing the sea that escaped from the underground ban!"

"What is it going to do?" Lu Chen asked as he fought against the black clouds.

"It wants to destroy your sea of knowledge, and the dove occupies the magpie's nest!"

After a pause, Gu Linglong continued: "This group of sea knowledge evil thoughts only has primitive instincts, and has not yet given birth to spiritual consciousness, if you are defeated by him and occupy the physical body, you will become the same existence as a beast. If I could use the power of sea awareness, it would be easy to destroy this sea awareness evil thought, but now I can only rely on yourself. ”

Just as Lu Chen and Gu Linglong were talking, the black clouds continued to boil and change, and a cloud of black gas separated from it and turned into a long knife as black as ink.

As soon as the black knife came out, the sharp and incomparable aura permeated Lu Chen's sea of knowledge, and Lu Chen only felt that his Xuantie sea of knowledge was about to be cut in half under this knife.

"This is my Zhihai, I can't help you with this evil thought that is rampant!" Lu Chen roared, and Zhihai changed in an instant with his mind. The sea of Xuantie Zhihai was like melting, turning into a stream of water, and then a stream of water separated, turning into a heavy spear of Xuantie, and the bright silver spear blade dragged out a silver lightning bolt in the air, and then pointed at the black knife.

With a bang, the black knife turned into a black streamer and slashed through the air, and the dark iron heavy spear transformed by the power of sea knowledge also swept towards the black knife. The black knife collided with the spear blade, and with a bang, the black knife that came from the chopping knife rolled back, and cracks appeared on the ink-black knife body, but it was not completely destroyed.

Click!

The heavy spear of Xuantie fell towards Zhihai, shattering into more than ten sections in response, and then dissipating into nothingness. Outside, Lu Chen's body shook wildly, his face became even paler, blood continued to overflow from the corners of his eyes on both sides, and at the same time, blood slowly overflowed from his ears and nostrils, making Lu Chen's appearance look even more miserable and hideous.

Under one blow, the Xuantie heavy spear transformed by the power of his own sea perception completely collapsed, and although the black qi long knife was full of cracks, it was not defeated, which was stronger and which was weaker, it was clear at a glance!

Seeing this scene, Gu Linglong's fishtail swayed, circling around Lu Chen's forehead, and after a while, she seemed to think of something, and hurriedly said: "This sea consciousness evil thought is stronger than yours, you are not his opponent, if you consume it for a long time, the one who will be defeated in the end must be you, I have a way to help you destroy it." ”

"What way?" Lu Chen asked, through the two encounters with the sea knowledge evil thought, Lu Chen already knew the power and terrifying of the sea knowledge evil thought.

"Retain a trace of Origin Spiritual Consciousness, and then the entire sea of consciousness will be wiped out with evil thoughts. Gu Linglong said. "But with only the Origin Spiritual Sense, I'm afraid you'll need to sleep for a long time. ”

"How long is a long time?" Lu Chen asked with a frown.

"It could be a month or two, it could be ten years or eight years, or it could take decades to wake up. Gu Linglong said: "Fortunately, you have cultivated to the Ice Muscle Realm, your physical body is strong, and you can withstand it, even if you recognize the sea and evil thoughts together, you should be able to sober up within a month or two." ”

As soon as Gu Linglong said this, Lu Chen's eyebrows couldn't help but jump. When he used the power of the ban to condense the sea of knowledge before, Gu Linglong also said that Lu Chen's physical body was too weak, and now he said that his physical body was strong enough, and he really didn't have any confidence at all. Thinking of Gu Linglong's unreliability, Lu Chen felt depressed for a while.

After thinking about it for a while, Lu Chen had a plan in his heart. Gu Linglong's method may not be reliable, and unless it is absolutely necessary, he still shouldn't use it lightly. Besides, he still has a killer weapon that has not been released, so he may not really lose to this group of sea knowledge evil thoughts.

At this moment, there was another change in the evil thoughts of knowing the sea, and a cloud of black qi suddenly separated from the black cloud, and the black qi flashed suddenly, merging into the black knife covered with dense cracks. I saw that the black knife hanging above the sea of knowledge was like being beaten with chicken blood, and the black gas around it suddenly became extremely turbulent. The swirling black gas continued to drill into the black knife, and then escaped from the black knife, back and forth, and the black knife, which was originally densely cracked, not only recovered as before, but even became more terrifying.

Seeing this, Lu Chen did not sit still, Zhihai set off huge waves, and another Xuantie heavy spear condensed out from Zhihai, like a dragon soaring out of the abyss, confronting the black knife in the air, and a domineering spear on the Xuantie heavy spear rose into the sky.

"You will definitely lose if you fight against it with such a move, and you must have a brave and enterprising heart in battle, listen to me, don't do it endlessly, and fight with it!" Gu Linglong said, and as she spoke, her fishtail swayed slightly.

Taking the moment of Gu Linglong's fishtail gently swinging into his eyes, Lu Chen's brows jumped slightly. Lu Chen felt as if he had faintly caught a pattern, every time Gu Linglong was unreliable, her fishtail would swing slightly. Lu Chen took a deep breath, simply closed his eyes and ignored Gu Linglong who was inciting him on the side, and concentrated on fighting against the evil thoughts of Zhihai.

The black knife slashed down in the air again, and the heavy black iron spear also stabbed forward, as if it wanted to pierce the sky.

With a bang, the movement of this confrontation was stronger than before, and the sea of knowledge shook violently, and the sea of knowledge, which was originally condensed to a radius of only one zhang, suddenly dispersed, and turned into a hundred, a thousand, a thousand zhang, really like a vast ocean. And the black clouds were also uncomfortable, almost like Lu Chen's Zhihai, they suddenly spread around, turning from a black cloud to a pitch-black cloud-covering cloud over the Zhihai.

And between the clouds covering the sky and the sea of knowledge, waves like the walls of a giant city rose wildly, colliding with the black clouds that fell down. I saw that among them, a Xuantie heavy spear was broken into several pieces, and gradually dissipated into invisibility, and the power of condensing the Xuantie heavy spear to recognize the sea was completely annihilated. The black knife became a broken knife, and it did not completely dissipate like the dark iron heavy spear.

Outside the sea of knowledge, Lu Chen's body shook wildly, his skin was like a long-drought earth, and the tough skin membrane under his skin was also cracked, and blood arrows shot out. The Zhihai Dragon Gate is roaring in the battle, the earth shakes the mountains generally, the Zhihai Longmen is a bridge connecting the physical body and the Zhihai, and the power of the battle in the Zhihai is transmitted to the physical body through the Zhihai Longmen.

Lu Chen originally thought that he would be able to occupy the right time and place by fighting in his own sea of knowledge, but he didn't expect to suffer from it now! What Gu Linglong said before was indeed not wrong, even if he cultivated to the Ice Muscle Realm, his physical body was still extremely weak, and he couldn't withstand the confrontation between his own sea of knowledge and evil thoughts.

Seeing that Yu Wei was scattered, the sea of knowledge continued to shrink, and after the stereotype, it was less than a square circle, and it disappeared for nearly thirty percent, and Lu Chen tried his best to stabilize his sea of knowledge. And the black clouds also rolled and converged, returning to their original appearance, although they were one size smaller than before, they were still arrogant and fierce.

Glancing at the black cloud, a gleam flashed in Lu Chen's eyes.

"Proverbs of Fire, Flame Dragon!"

Lu Chen shouted, less than a square circle of the sea of knowledge was born a spark, the sparks appeared from the sea of knowledge rushed out of the sea of knowledge to converge over the sea of knowledge, after a short time a lifelike flame dragon flew in the air, the flame shined like a round of scorching sun in the sky to emit dazzling brilliance, the scorching sun in the dragon chanting.

The Flame Dragon was present, and the Black Cloud of Evil Thoughts seemed to feel a strong threat. I saw that the black gas was tumbling like a boil, and the huge clouds were constantly deformed, and finally condensed into a huge heart. The pitch-black heart beats, and the blood vessels as thick as iron chains crawl on it, undulating with the beating of the black heart.

Knock knock! knock knock......

The black heart beat in a peculiar rhythm, and circles of substantial ripples escaped out, blasting through the Zhihai Dragon Gate towards Lu Chen's body.
