Yiheng first drove the Liuyun Boat to the edge of the rock wall, and according to his speculation, the place where these rock walls could exist was naturally safe for him.

Then, Yiheng slowly went deeper.

The lower you go, the brighter the stone on the rock wall is, but it's still just an ordinary stone, until Yiheng sees a red crystal-like stone, which is the Blood Flame Crystal, and it is rumored that the Night Rain Crystal is evolved from this stone.

Yiheng leaned over carefully, took out the black spear and slammed it into the rock wall, and then directly picked out the blood flame crystal, with warmth, the size of a fist, and the blood flame contained in it was richer than what he absorbed in the lake.

Put away the blood flame crystal, and Yiheng continued downward.

After descending about thirty meters or so, Yiheng came to the bottom of the rock wall, and along the way, he collected a total of three blood flame crystals.

However, compared to the Blood Flame Crystal, it is more important to find a way out quickly. Yiheng looked at the bottom of the rock wall like a cone of thorns, thought about it, and carefully passed through it below, and then came to a wider bloody lake.

Yiheng set up the Liuyun Boat and hurried forward, and then stopped in a crimson water, looking at the wisps of red flowing in the lake, Yiheng moved his mind.

The yang flame here is obviously more intense, if it is refined and absorbed here, the quenching effect will definitely be better, and if you have an idea, it will be executed immediately.

Yiheng spread out the Shenyuan and integrated it into the light curtain, and then directly filtered out a stream of yang flame air and converged towards his body. The yang here is different from the yang heat when absorbed by the lake surface, although it is rich, it is more domineering.

The yang flames in the body were like a stream of hot water, with an extremely strong bloody aura, which was difficult to resist for a while, and he spit out a mouthful of blood violently, and then had to stop to refine the remaining bloody qi in his body first.

The Heavenly Pole Divine Yuan can refine this bloody evil qi, but the speed is extremely slow, and when he thinks about it, he runs the immortal divine canon, and the red divine element is replaced by the black divine element, and it flows, but a few breaths are to burn the evil qi in the body to nothing.

The magic of the Black Divine Yuan has been seen many times, but he is still a little shocked, compared to the Heavenly Extreme Divine Yuan, the Black Divine Yuan is much stronger. He remembered very clearly that even Liu Hefeng's Seven-Rank Origin Origin Divine Yuan burned when he came into contact with the black flames.

Sensing that the black divine element was feasible, Yiheng concocted it again, and the yang flame that had been washed by the black flame became extremely gentle, and it was even much easier than when he used the red yuan to absorb it on the surface of the lake.

Yiheng couldn't help laughing, the Immortal Divine Code cooperated with the Heavenly Dragon Yin, and then wantonly absorbed the Yang Yan and refined the kidney. Drops of blood continued to condense into red droplets, and the blood-colored lake, which was already thirty zhang wide, began to expand step by step.

When Yiheng absorbed the yang fire wholeheartedly, he didn't know that danger was coming to him. In the depths of the lake, a pair of fiery red eyes lit up, which was originally a red lake, but compared to that pair of eyes, it was too dim.

A seven-foot-long behemoth leaned towards him, swimming like a fish in the water, agile and fast. The fiery red eyes became more and more moonless, and when they got closer to Yiheng, there were even bloodshots.

For some reason, he suddenly burst into anger and attacked Yiheng.

Yiheng immediately sensed that something was wrong, and the strong fluctuation of the water made him sense the danger early, and then quickly evacuated from the place and came to ten zhang away.

Then, he looked in the direction of the fluctuating current, and a bucket-like thick fire python flashed its fiery red eyes, swam towards him again, and spat out a rocket from its open basin mouth, and it came to him in an instant.

Yiheng urged Liuyunzhou to hurriedly dodge and fight in the water, but it was a little inconvenient. After thinking about it again, Yiheng took out the black spear again.

"How can you feel a trace of dragon qi?" Yiheng cultivated the Heavenly Dragon Yin, and his perception of dragon qi was naturally keen, and he felt a trace of it on the fire python behind him, which was very faint.

Yiheng dodged while looking for an opportunity to make a move, this fire snake obviously swam from the depths of the water, but it was only a spirit level, and its breath was much weaker than that of Renjie, but it was extremely sensitive.

Yiheng wanted to know why it had dragon qi on it, so he didn't rush to make a move, what he wanted was a one-hit kill. A starry sky lit up in his body, and Yiheng urged all the divine soul power, instantly accelerated for the Liuyun Boat, and then headed towards the front of the fire python.

The black thunder in his hand exploded, and Yiheng stabbed with all his strength with his gun, and then a nail exploded the fire python. Black flames surged out and spread over the spear, burning the entire body of the fire python.

The huge fire python corpse shrouded in black flames was condensed at an extremely fast speed, and finally turned into a star of red light, Yiheng reached out and grabbed it, and there was some disappointment when he was excited.

The star-sized red light on his hand is true blood, and Yiheng can feel that it is the true blood of the dragon, but it is too little. "I'm afraid a dozen more will be enough to make up a drop. ”

As Yiheng's words fell, the fiery red eyes suddenly lit up in pairs, as if he heard Yiheng's heart, and swam rapidly from the depths of the lake.

And some of the aura emitted by them was much more powerful than the previous fire snake.

Yiheng's face was shocked, just now he killed the fire snake with one shot by virtue of his speed, and now he is facing so many of them, how can he deal with it? Yiheng smeared oil on the soles of his feet and slipped away.

It's just that more than a dozen fire snakes seemed to be staring at him, and they swam towards him one by one, and they came up to attack. Yiheng urged the flowing cloud boat to constantly shuttle in the water.

He didn't know which direction he should go next, if he encountered a dead end, then he could only use Qianli Ruyi today, and just as he was struggling, a small snake climbed on his shoulder.

The little black snake actually woke up, but it wasn't it that woke up naturally, but Yiheng threw it into the true blood of the dragon just now.

Seeing the little black snake, Yiheng suddenly had confidence, this little guy was extremely sensitive to the things of the dragon clan, took his white jade bone sword and the heavenly dragon lead, and also devoured many Black Thunder Emperor dragon beast souls, he would definitely be able to help him.

As soon as the little black snake appeared, his eyes lit up, and the snake hyacinth hissed, as if ready to make a move at any time.

"All I need is a drop of true blood, and the rest is yours. Yiheng said directly, in fact, he didn't know if the little black snake could handle so much, but he had seen the process of it devouring, and there was nothing left.

The little black snake nodded, rushed out, and then met a big mouth and was swallowed directly. Of course, you can't just get a bento.

A black mist emanated from the surface of the fire snake's body, and then the huge body quickly turned into a little red starlight. As concocted, one by one the fire pythons died completely and easily.

Although the strength of these fire snakes is not weak, their spiritual intelligence is not high, and they are even eroded by a violent force like the blood flame demon beast. Beasts in this area seem to be affected by this.

Of course, the little black snake seems to be something else!

Yiheng collected it little by little, and finally gathered fifteen parts and condensed it into a drop of dragon true blood, and suddenly the sound of the dragon's howl sounded, and a red dragon turned into a shadow, tyrannical and ancient.

Yiheng hurriedly ran the Heavenly Dragon Lead, and at the same time, the black flames shrouded the dragon shadow, and the red dragon roared a few times, but it showed fear, and then obediently turned into a drop of rich and bright red true blood, which can be seen that there is a red dragon shadow hovering in it, lifelike.

This is the power of the bloodline, and a drop of true blood has such power.

The little black snake looked at this drop of true blood curiously, and its eyes flashed with excitement, but it didn't rush to swallow it, obviously it was deeply impressed by that black eye Yiheng.

The little black snake kept looking towards the bottom of the lake, as if it wanted to go down and explore. Yiheng roughly talked about his perception of the barren land, and after listening to it, the little black snake swooped into the lake.

Yiheng hesitated for a moment and didn't follow, it was very dangerous down there, and the strangeness here must be related to the Great Emperor of the Protoss who fell here in the first place. This depth of Yang Yan is enough for him to absorb, so it is better to continue to refine the kidney hidden.

Dripping.

Time passed little by little, and three days later, with a crisp sound, Yiheng completely quenched the kidney reservoir, and a ninety-three-zhang wide blood lake appeared, surrounded by a hazy and undeveloped riverbed. In the depths of the bottom of the lake, you can see that there are bright red blood lines crawling all over, flashing scarlet light, and the divine patterns appear spontaneously.

Yiheng was overjoyed, seven days of yin and yang time had already passed, and he had to leave here as soon as possible. Otherwise, by the time the sun erupts, it will be too late.

So, you have to find your way out first.

"Little Wyvern, you're leaving. Yiheng shouted loudly, before the little black snake made a meritorious service, Yiheng shouted out this name without hesitation.

After waiting for half a ring, he finally saw a black shadow swimming towards him, extremely fast.

"Hey, although I felt that you had grown up a little before, but now that I am watching, how do you feel that you have grown up a lot?" Yiheng asked curiously, could it be that the little black snake found a treasure at the bottom of the lake?

The little black snake lay on Yiheng's shoulder, and obediently arched on Yiheng's body, and then his golden eyes blinked a few times, and when he opened his mouth and spit out, a fist-sized spar appeared, which turned out to be a blood flame spar.

The intensity far exceeded the three pieces in Yi Heng's hand, and the little black snake spit out fifteen blood flame crystals in a row, and then shook his head with vigour, like a child waiting to boast.

Yiheng touched the head of the little black snake and praised without hesitation: "Well, yes, I also know that I can leave a little and bring it back, which is worthy of praise." ”

Yiheng guessed that the little black snake must have found a lot at the bottom of the lake, otherwise it would not have taken so long to come back.

He had planned to have the saber-toothed tiger come out and try it out, but it failed, and the brute beast would lose its mind here. These blood flame crystals brought back by the little black snake can be rewarded to the saber-toothed tiger.

Sacrificing the Liuyun Boat again, Yiheng hurried away in the direction pointed by the little black snake snake Xinzi, and soon came to a rock wall, and had no choice but to continue to dive down.

This time, Liuyunzhou didn't seem to be able to withstand the power of Yang Yan, Yiheng hurriedly put it away, wrapped his whole body in black flames, and then continued downstream.

Soon he found the bottom of the rock wall again, carefully crossed it, and then came to a huge body of water, and the red flames seemed to be attracted, and they actually flowed in a certain direction.

Yiheng followed the direction of the flow and went up rapidly.
