Ye Li was also looking forward to this. He nodded and looked at the fog ahead excitedly.
As he continued to go deeper into the valley, Ye Li could faintly feel waves of Yin Fire power from the black fog in front of him, just like the tide surging forward one after another.
The power of this Yin Fire is very strong. Even from a long distance, Ye Li can feel the powerful power contained within it.
"Be careful, Ye Li!
We don’t know the situation here, so who knows what kind of dangers there are.”
Tunri also felt this power and spoke to Ye Li with a serious expression.
Ye Li nodded and responded when he heard this, then he carefully walked through the fog and headed forward.
More and more sticky black fire gushed out around him. This flame, which looked like magma, caused him a lot of trouble.
Ye Li tried to resist with his own strength, but found that he could only defend for a short time. If it lasted a little longer, he would not be able to bear it.
Ye Li couldn't help but sigh inwardly. His attack power was strong enough, but he had never been very good at defense.
After all, the Nine-Colored Divine Armor Talisman cannot be used here, and he does not have any spiritual armor. He can only rely on the secret body-casting method to defend himself, which sometimes seems a little insufficient.
Ye Li walked about a hundred meters further along the valley, and there was basically no fog ahead.
It wasn't that the fog dissipated on its own, but because waves of black flames gushed out from the depths of the valley, dispersing all the fog.
This black flame tide was exactly what Ye Li had just vaguely sensed. It was extremely powerful, especially in the depths of the valley, where its power was greatest. The further it surged toward the periphery, the thinner it became, and its power weakened accordingly.
Not knowing where this tide came from, Ye Li stood in a remote area that the black flame tide could reach and felt it quietly for a moment. He found that even if this tide was in a very thin state, it still had a strong corrosive and burning ability.
Ye Li's defenseless body was unable to resist the destructive power of this force. Only by activating the secret techniques of Casting Yang and Casting Fire, and using the Yang Fire formed by the combination of these two forces, could he barely resist the erosion of the Yin Fire.
In theory, Ye Li's Yang Fire is of the same level as Yin Fire, but after all, the power of the laws he has mastered is limited, and he is unable to fuse the power of Yang and fire to a perfect state. Compared with the Yin Fire here, the quality is much worse, so even though the attributes are mutually exclusive, he is still at a disadvantage.
Ye Li looked at the cliffs on both sides, wondering whether he should climb up. By walking forward from the cliffs, he could avoid the black flame tide in the valley.
However, when Ye Li tried to climb the mountain wall, he found that he could not touch the wall at all.
These mountain walls seemed to be normal at ordinary times, but when he placed his hands on the rock wall and prepared to climb, streams of Yin Fire seeped out from the rock wall and burned his palms.
Fortunately, Ye Li realized something was wrong and let go immediately. If he had held on a little longer, he estimated that his hands would have been broken.
The Yin Fire directly melted his Yang Fire and then burned his flesh. Ye Li felt the essence and blood in his body rapidly dissipating.
Fortunately, after he let go, the Yin Fire had no follow-up power to replenish it and quickly dissipated, otherwise he was sure that he would not be able to save his hands.
This time, Ye Li didn't dare to get close to the rock wall anymore. He secretly cursed himself for being so stupid. If he could climb the cliff and pass the test, then everyone who came in before should be able to do it. It wouldn't be difficult for anyone.
After thinking about it, Ye Li took a look at the waves of black flames surging out, and couldn't help but sigh: "It seems that the only way to go in is from the front. After all, the black flames on the rock wall are constantly gushing out, and the black flame tides are like the tides, surging in waves.
I wonder if I can make it through by taking advantage of the gaps between the tides?"
Ye Li murmured.
"Anyway, you better be careful. The interval between each tide is uncertain. Look at the front of the valley. There is a protruding mountain wall. If you can take advantage of the gap between the tides to rush there and hide, you should be able to go deeper."
After observing the situation ahead, Tunri said to Ye Li.
Ye Li nodded and said, "I think so too. These Yin Fires are extremely lethal to living creatures, but their destructive power to rock walls is very weak.
If I hide in that position, the Yin Fire Tide will definitely not be able to hit me head-on."
After making up his mind, Ye Li crouched and stood at the very edge of the Yin Fire Tide, constantly feeling the black flame tides of varying speeds surging out from the depths of the valley.
Suddenly, a Yin Fire tide with a slightly longer interval appeared in front of Ye Li. The moment the first tide just dissipated, Ye Li suddenly exerted force on his feet, and his body shot out like lightning, bringing with it two consecutive thunderous roars.
Ye Li burst out at his maximum speed, traveling between the two black flame tides and drilling deeper into the valley at the fastest speed.
Not far in front of him, a subsequent tide of black flames was coming towards him. The black Yin Fire had blocked all places in the valley where he could escape.
Moreover, as he went deeper, the power of the Yin Fire continued to increase. The black flame tide in front of him was much more powerful than the one that dissipated behind him. Ye Li didn't even plan to test it. He felt that this tide could instantly destroy his entire body's defenses and burn his flesh and blood dry.
Fortunately, the protruding rock wall in front was getting closer and closer. Ye Li bent over and dodged, and his speed increased again, bursting to the extreme. He followed the black flames surging in front and got behind the mountain wall that he had previously favored.
As expected, the black flames were straight forward, and these Yin Fires would not take detours either. After passing by Ye Li, they sprayed towards the outside of the valley.
"Huh... The first wave has passed, and there should be two more waves ahead. If I can avoid all the black flame waves, I should be able to reach the bottom of the valley."
Ye Li said after taking a breath.
He leaned against the stone wall next to him and looked forward. There was a protruding rock wall on the mountain wall not far ahead. If he used the same trick again and rushed over through the gaps between the black flame waves and hid there, he would be one step closer to the bottom of the valley.
Ye Li took a deep breath and began to calmly feel the fluctuations of the black flame tide.
Just as the wave surged again, Ye Li jumped out from behind the protruding rock wall and rushed towards the protruding rock wall in front at the fastest speed.
He moved quickly. He had already made careful observations beforehand. This time, the interval between the two waves of black flames was relatively long. As long as Ye Li moved fast enough, he would be able to successfully hide behind the protruding rock wall in front.
