The purple snake also realized that something was wrong, and looked at Zhao Yuan with even more resentful eyes, Zhao Yuan didn't pay attention to it, but the next moment, a strong cold wind filled the entire corridor, and soon, ice cubes were hung on the walls, and frost was also paved on the floor. In this corridor with a small space, the temperature is getting lower and lower, and Zhao Yuan, as a spellcaster, is naturally fine, and the purple snake, which is naturally a cold-blooded animal, can't stand it. Its agile form stiffened, and at last its struggle grew slower and slower, and it became motionless like a hard stick, its frightened eyes still open, and the expression was vividly fixed on its face.

Zhao Yuan knew that the purple snake was only frozen and not dead, but he didn't panic and directly grabbed the purple snake and threw it into the seven-star ring. You can't put a living thing in the Seven Star Ring, if you throw a living thing in, it will be a dead thing when it comes out, Zhao Yuan is not worried at all.

However, if you want to throw a living creature into the space ring, the owner of the ring must be higher than the other party to do it, otherwise it will be messed up.

Solving this snake that has been dripping saliva behind his back, Zhao Yuan's heart finally relaxed, he is not afraid of those powerful and hideous monsters, but he is afraid of the unknown, what is snooping in the dark. It is also true that people are afraid of ghosts, although Zhao Yuan grew up in a society full of high-tech, he still has some inexplicable fear of those things that the gods are talking about.

Fortunately, this time it was just a snake, Zhao Yuan comforted himself. In the future, you still can't rely too much on spiritual power in everything, who would have thought that such an ordinary low-level demonic beast would be able to evade the detection of your ninth-order spiritual power.

Zhao Yuan put what had just happened behind him and continued to walk down the revolving corridor, and this time it didn't take long for him to see the exit.

Who would have thought that in such a deep underground, there would be such a huge and beautiful lake, Zhao Yuan's eyes widened, and he looked at the scene in front of him with a hint of disbelief.

The lake in front of you is so blue that it looks like a piece of sky has inadvertently fallen to the ground, and the water is crystal clear and sparkling. There are a few lotus leaf-like plants floating on the water, which is quiet and far away. The most amazing thing is that such a large lake actually exudes an unknown light by itself, illuminating the entire space.

Zhao Yuan raised his eyes and looked into the distance, only to see that the lake water occupied the entire underground cave, and the surrounding rock wall was also flat, which was an artificially dug underground lake. He now and more did not understand what the builder of this ruin was thinking, and he had gone to great lengths to build such an elaborate underground work, and if it had not been for the adventurers who wanted to make a fortune to come here, this place would never have been seen by the world.

Zhao Yuan approached the lake, but suddenly smelled a very faint smell that could not be ignored. It wasn't a pleasant smell, but Zhao Yuan couldn't tell what it looked like, it smelled a little like egg whites, but it wasn't really, it could only be said that it was a very unfamiliar and disgusting smell.

He stared down at the lake in front of him, a gust of wind from nowhere blew across the lake, blowing the slim lotus flowers on the lake and swaying twice, Zhao Yuan looked at the lotus not far away, the nerve endings couldn't help but tremble, and somehow a sentence popped up in his mind, "Out of the mud but not stained, clear ripples but not demons."

There are only clear ripples in this place, as for the silt, there are a lot of them in the swamp above, Zhao Yuan didn't know why he thought about these endlessly, his thoughts seemed to be a little trance.

Just as he was about to fly over and pick a lotus flower to take a look, a voice suddenly came out of his mind: "It's the smell of snakes." ”

"What?" Zhao Yuan paused.

Brother Xiong continued: "It stinks here, it's full of snake smell. ”

Zhao Yuan was startled in his heart, and suddenly rose into the air, almost at the same time, the crystal clear lake water seemed to be boiling, and clusters of splashes were set off on the water surface, as if a group of things broke out of the water.

The continuous impact sound of "bang bang bang" sounded around Zhao Yuan, and the transparent magic shield beside him lit up after being impacted, revealing the appearance of the attacker.

Snake. It was a group of completely transparent snakes, in Zhao Yuan's spiritual power realm, they came and went without a trace, leaving no trace.

Zhao Yuan gritted his teeth, and his voice almost came out of his throat: "How come, I can't detect them at all......" He stared at the lake below, and the smell lingering on the tip of his nose became stronger, all of which were strange smells.

At this moment, the entire lake actually boiled, and countless invisible snakes crashed towards him, making a continuous "thump" sound on the magic shield. Those snakes bounced up from the lake, collided with Zhao Yuan's magic shield, and then fell into the lake, but they went forward one after another, attacking Zhao Yuan at any cost, and the mana in Zhao Yuan's body was also rapidly draining.

While stuffing the crystal nucleus into his mouth, he used his spells to frantically attack the invisible snakes that kept attacking below, only to find that those snakes completely ignored his attacks and shuttled freely from his spells, Zhao Yuan saw it, and his temples jumped suddenly.

"It can't be. Zhao Yuan gritted his teeth, if these snakes were immune to his magic attacks, they would definitely be able to penetrate his magic shield, it was impossible for this to happen, it didn't make sense logically.

Now the mana he output was enough to hollow out five or six eighth-order archmages, but Zhao Yuan was like a tireless artillery battery, attacking the lake below with different methods. One moment ice, one moment fire, or thunder, wind, and even a few healing techniques, he simply reviewed all the spells he knew. However, the lake below and those transparent snakes were still not disturbed in the slightest, and they kept attacking Zhao Yuan all the time.

Zhao Yuan was a little stunned by this endless attack like a river, but at this time, he heard Lao Xuanwu's slow voice in his mind: "Your spiritual power doesn't work here, just don't let it out." ”

Zhao Yuan thought about it, too, and simply withdrew the spiritual power that had been desperately searching around but found nothing, and suddenly, the entire sea of knowledge was filled with silver spiritual power, Zhao Yuan's spirit was lifted, and the whole person was a lot more sober.

At this moment, Zhao Yun noticed that something was wrong. When all his spiritual power returned to the sea of knowledge and stuck to his origin, he felt an inexplicable sense of detachment from the outside world. The scene in front of him looked very lively, the sky was full of mist, and there were invisible snakes constantly hitting his magic shield, making a "thump" sound. But in his core consciousness, he was alone in a silence, his heart was cold, and his hair was cold.

He felt that he was in nothingness, but what he saw and heard was not, and the noisy scene around him seemed to be covered with a layer of mist, as if he could poke a hole in the picture with a gentle poke.

"If anyone else is in this ghost place, I'm afraid I would have died of exhaustion. Brother Xiong didn't know if he was shocked by Zhao Yuan's extraordinarily strong mana, and he unconsciously exclaimed.

Zhao Yuan was stunned for a moment, and Brother Xiong's words made him suddenly understand. The next moment, I saw that he suddenly removed the magic shield on his body, and he no longer used magic attacks.

"Zhao Yuan be careful-" Before Brother Xiong finished speaking, he saw those transparent snakes swishing through Zhao Yuan's body, as if Zhao Yuan did not exist, and Zhao Yuan did not change his face, allowing those snakes to attack him.

"This ......" Brother Xiong said in confusion, and then he heard the voice of the old Xuanwu sounding slowly: "Sure enough, this is another illusion, but it is much more powerful than the previous one, and I didn't notice anything unusual at all." ”

The more transparent snakes passed through Zhao Yuan's body, the paler Zhao Yuan's face became, and he swallowed a small handful of crystal nuclei before his face regained its blood color. At the same time, the scene in front of him changed dramatically.

The huge crystal clear lake in front of me is still there, but the bottom of the lake is no longer ordinary silt, but a pile of bones. The bones were old and pale, silently telling Zhao Yuan about the sadness they had immersed in the ground. Zhao Yuan's sharp eyes found that those bones were all snake bones, in the shape of long strips, thick and thin. Some of them were giant pythons that could not be wrapped around the hands of adults, and some were small snakes the thickness of fingers, and now, their bones are stacked on top of each other at the bottom of the lake, which makes people feel cold.

On the surface of the water, those lotus flowers were still there, but when Zhao Yuan looked at them at this time, he inexplicably felt that these flowers were very delicate, as if they had absorbed some great nutrients from those bones.

At this time, the water surface was calm, there was no wind in the underground cave, and the lake surface was like a huge mirror, and it was incredibly smooth.

But soon, this near-perfect calm was broken by the man suspended in the air above the lake, who saw him with a grim face, a simple staff in his pale but bony hand, and the magical elements gathered wildly around him, as if falling into a selfless carnival.

The power of the eighth-order archmage was vividly displayed by Zhao Yuan at this moment! Flames, countless flames, continuous, burning, filling the entire huge karst cave. The air was scorching hot, and the entire space became a field of fire. Zhao Yuan stood in the flames, his pale face was illuminated by the firelight, and the light in his eyes was bright and dark, obscure and mysterious.

The lake below began to evaporate under the heat of the flames, and wisps of white mist drifted towards the sky, and the air had a stronger and stronger smell, like the smell of egg whites, but it was very unpleasant.

"It's Venom. Zhao Yuan's voice was muffled, and around him, the light of the magic shield lit up again. Some mist rose from below and hit his magic shield, making a sizzling sound, like pouring oil into a hot pot. He looked at the water below at the steaming water, and his eyes flowed, as if to say to himself, "The whole lake is full of snake venom." ”
