"What is this?" Chu Nan licked his somewhat dry lips, this place was really weirdly tight.

"This river should be the Nine Yin Land River, no wonder it will give birth to the second-level spiritual fire of Yin Evil Fire, and the creatures in it are also Yin Spirit creatures, and Yin Spirit creatures are originally devouring each other to enhance their strength. Lu Lianxiang said.

"Then won't they attack us?" Chu Nan asked.

"Of course...... Yes, they attack everything that is alive. Lu Lianxiang said.

"What is the relationship between the Evil Spirit Clan and the Yin Spirit?" Chu Nan asked.

"The evil spirit clan is an intelligent life, the yin spirit is not, and although they are all energy-based beings, their essence is not the same, the evil qi and the yin qi feel similar, but in fact, they are not the same...... If you ask again, you will have to charge tuition. After Lu Lianxiang answered, she found that she had no obligation to teach him, there were some things that the students of the academy could not learn, and only the teachers could teach them, so the status of the teacher and the master was far apart, a student may be inferior to the teacher, but in front of the master, he is a grandson.

"Tuition is not an issue. Chu Nanhao said angrily.

"Ten million top-grade Xuanjing. Lu Lianxiang said, looking at Chu Nan's instantly sluggish expression, the corners of her mouth pulled slightly, she hadn't felt like laughing for a long time.

"Well, well, let's go find the sinister spiritual fire. Chu Nan rolled her eyes, 10 million top-grade Xuanjing, she dared to open this mouth.

The two searched along the upper reaches of the Nine Yin River, and Lu Lianxiang estimated that the source of the Nine Yin River should be the hiding place of the Yin Evil Spirit Fire.

After walking a short distance, the mine road forked, but the Jiuyin River was submerged in the rock.

Lu Lianxiang jumped down without saying a word, hanging upside down on the rock layer above the Jiuyin Earth River like a gecko, and quickly moved forward.

Chu Nan also followed, gecko swimming on the wall is a small meaning to us.

The water surface of the Jiuyindi River was two or three meters away from the rock layer at the beginning, but the further they went, the lower it was from the river surface, and after nearly a thousand meters, the rock wall directly flooded into the water, which means that if they wanted to pass through, they had to soak the whole person into the water of the Jiuyindi River.

Lu Lianxiang glanced back at Chu Nan, but she didn't expect that he could also move easily in such an environment, she pointed to the rock wall in front of her that was immersed in the Jiuyin River, as if asking him if he could do it?

How could Chu Nan be cowardly, and gestured to tell her the problem.

Lu Lianxiang took a deep breath, and the phoenix jade on her body emitted a faint red light that enveloped her, and she quickly sank into the water of the Jiuyin River along the rock wall.

"Damn, why don't you join us? How can you treat your lifesaver like this. Chu Nan shouted in his heart, took out a bottle of mystical medicine and poured it down, and his limbs suddenly gave birth to a burst of warmth, and he hurriedly crawled forward, and his body was also immersed in the Nine Yin Land River.

As soon as he entered the water, he shivered, and the biting yin qi was overwhelming to enter his body, but fortunately, he had taken a bottle of third-level cold wardring elixir from Old Man Mo in advance, coupled with his own physical fitness and the urging of Xuan Li, he could barely resist.

More than 200 meters ahead, Chu Nan felt that the rock wall was rising again, and he was overjoyed.

But at this moment, a pair of strange cyan eyes appeared in the Jiuyin River and instantly launched an attack on him.

In such an environment, Chu Nan couldn't dodge effectively at all, he could only rush forward as fast as he could, hoping to get out of the Nine Yin River.

Just as Chu Nan stretched out one hand on the surface of the Nine Yin Earth River, his speed suddenly stagnated, and a huge pulling sensation came from his feet.

The hairs on his body stood on end, his feet twisted, and the Xuan Li shook out a circle of crystals, and the black shadows wrapped around his feet suddenly loosened a lot.

At this time, a line of fire entered the Jiuyin River from the top of the slope.

The water of the Jiuyin River was agitated, and then the black shadow wrapped around his feet suddenly receded completely, and Chu Nan took the opportunity to rush out, and with one mouth, the breath that spewed out turned into a cold white mist.

Not far away, Lu Lianxiang was looking at him.

"Thanks, thanks. Chu Nan's voice trembled slightly, if he stayed in the Nine Yin Land River for a longer time, even if there was no Yin Spirit attacking him, he would be frozen into a popsicle.

Lu Lianxiang didn't say anything, but was a little surprised that he could survive.

The two of them climbed a short distance further, and the rock layer above disappeared, replaced by a crack in the underground rock hundreds of meters high, but fortunately there were some protruding rocks at the edge that people could stop or borrow.

On a protruding boulder, Chu Nan took out two mystical elixirs and poured them into his mouth, and then sat down cross-legged, and after a while, his body was filled with smoke, his clothes were dry, and the cold was also expelled.

Lu Lianxiang was on another boulder, closing her eyes and recuperating.

An hour later, the two of them once again followed the Jiuyin River to trace the source of the Jiuyin River.

Slowly, the line of sight in front of him became wider and wider, as if this earth crack was expanding to both sides without limit, and the yin qi in the Nine Yin Land River became thicker and thicker.

At this moment, the two saw the end of the Jiuyindi River, the rock walls on both sides were already seven or eight hundred meters apart, and the rock wall at the end circled the Jiuyindi River into an oval, and there were large springs gushing out everywhere, and in the center, there were several boulders standing in the center, and there were several figures standing on it, and at the foothills on the surrounding rock walls, there were also more than ten or twenty people standing.

The appearance of Chu Nan and Lu Lianxiang attracted a lot of attention, and they were not surprised to see Lu Lianxiang, but they were a little surprised to see Chu Nan also appear here.

Everyone has personally experienced the dangers of this secret land, and it is not easy for people in the Xuanli realm below the seventh level to survive here, especially in this Nine Yin Land River, there are many powerful Yin Spirits, could it be that Lu Lianxiang, the ugly monster, has protected him all the way?

"Dogs and men, take your life. At this moment, a resentful voice sounded, and two men and a woman with disheveled hair launched an attack on Chu Nan and Lu Lianxiang.

Take a closer look, but it was Su Hao and Wu Sili who had just appeared from the crack next to them, Wu Sili entangled Lu Lianxiang, and Su Hao attacked Chu Nan, it seemed that he would not stop if he was not flayed alive.

Lu Lianxiang's internal organs were healed, and she couldn't spare the spirit to help Chu Nan for a while.

Chu Nan, a person who had only just been promoted to the sixth level of Xuan Bing, faced the surprise attack of Su Hao, who was about to break through to the realm of Xuan General, did not mess up, although he was a little embarrassed, but his body was strange, and he made full use of the protruding rocks everywhere on this rock wall, and was stunned to avoid Su Hao's three fatal attacks, but there were a few wounds on his hands and feet.

"Die!" Su Hao was so angry that Chu Nan's eyes turned red, his figure soared, and the sword in his hand suddenly erupted with dozens of blade lights, and the air was cut into a whimper.

Chu Nan's pupils shrank, there was no way to avoid it, and Su Hao's blow was stuck in his old power, and when his new power was at the end of his life, he only had time to adjust the angle of his body, and four or five sword blades slashed at him.

The huge force slashed at Chu Nan's body, causing his entire body to be embedded in the rock wall.
