"Die!" Mo Aotian was suddenly furious, and with a push of his palms, a thunderbolt visible to the naked eye suddenly flew towards Zhang Ze!

Zhang Ze hugged his head and sank to the bottom of the water again to avoid the attack, but he didn't dare to continue to surface, otherwise Mo Aotian would definitely kill him!

"System! Find a way!" Zhang Ze frantically called for help underwater.

“...... Host!This system has made an amazing discovery!" the system said with sudden delight.

"Damn, when is it, hurry up and find a way to save me!" Zhang Ze was about to vomit blood, at this juncture, the system was still rippling!

"No, host, listen to me. The system explained, "I just explored this place and found a secret passage under the Blood Demon Pool!"

When Zhang Ze heard this, his heart was suddenly overjoyed, and he hurriedly asked in his heart: "Why didn't you say it earlier, hurry up and show me the way, I escaped from the secret passage." ”

The system hesitated and said, "But...... This secret passage cannot be escaped, because at the end of the secret passage is a confined space, there is no exit, and the only exit is this blood demon pool. ”

“...... Is there air in that confined space you're talking about?"

"Yes, the air quality is not very good, but it is still breathable. The system replied.

"......" Zhang Ze thought about it, and decided to enter the confined space through the secret passage, at least, he was killed by Mo Aotian!

"Show me the way, I'll go to the secret passage!"

The system said in Zhang Ze's ear: "Okay, but please prepare the host, because this secret passage is relatively long, I am worried that the host will not have enough lung capacity......"

Zhang Ze interrupted the system impatiently and said, "Don't talk nonsense, I'd rather be suffocated to death than die in the hands of Mo Aotian!"

"Now that the host has come to his senses, the system will immediately point you to the location of the channel. The system stopped talking nonsense, and immediately teleported a map to Zhang Ze's eyes, Zhang Ze took a look, and found that his fellow Dao was at the bottom of the Blood Demon Pool.

"Could it be that the water in the Blood Demon Pool flows from which confined space?" Zhang Ze muttered in his heart, and then he swam to the bottom of the water with all his might.

In the Blood Demon Pool, Mo Aotian was still waiting for Zhang Ze to come out, and then grabbed him and interrogated him.

As a result, after waiting for a long time, I didn't see him show up, and I couldn't help but wonder, could this kid drown himself?

At this time, the hundred-eyed python "Sisi" was spitting snake letters, Mo Aotian glanced at it, shook his head and said: "No, below this blood demon pool is the forbidden land of our demon sect, ordinary people are absolutely not allowed to enter it, otherwise it will be death!"

"Don't say it's an ordinary person, even I can't make an exception, because I swore to heaven on the first day of my initiation that I would not trespass on the forbidden land, otherwise there would be five thunderstorms in the sky!"

Speaking of this, Mo Aotian showed a look of jealousy, the oath was absolutely effective in the True Martial Continent, and it was extremely powerful, comparable to the Heavenly Tribulation! If ordinary people dared to break the oath, then wait for death.

"Okay, hundred-eyed python, you stay here, I'll see when this kid will come out!" Mo Aotian snorted and laughed: "I don't believe that he is an ordinary person, and he can stay in the water for a lifetime?"

Under the Pool of Blood Demons.

Zhang Ze dived down hard, but he felt that he had dived a few hundred meters deep, and the result didn't seem to be at the end!

How deep is this special blood demon pool!

Feeling that his oxygen was a little insufficient, Zhang Ze's face was full of anxiety, now his diving speed was already the fastest, he couldn't be fast, if it was at the current speed, it was estimated that before he reached the bottom of the pool, he would be in a coma due to lack of oxygen.

"System, I'm running out of oxygen, do you know what to do?" Zhang Ze called the system.

The system was silent for a moment and said, "Host, this system can temporarily stimulate your body's potential, but it won't last long, and it will also cause damage to your body, do you agree?"

"Agree! As long as I can survive this calamity in front of me, I will agree!" Zhang Ze shouted: "You can start quickly!"

The next moment, Zhang Ze hurriedly felt as if he had been pricked by needles all over his body! It was sore, painful, and numb!

He couldn't help but open his mouth, wow, and shouted, but as soon as the sound came out, he was poured into his stomach by the water in the pool!

"Damn! This is the old devil's bath water! I don't want to drink it!"

Zhang Ze immediately closed his mouth, miraculously, he felt that his body seemed to have regained his strength, and his breathing was not so difficult, he knew that it must be the system that stimulated his potential, he immediately continued to dive to the depths of the water, and this time the speed also became extremely fast!

It's like a nimble fish, swimming underwater!

Zhang Ze swam to the bottom of the water in one breath, and then he saw a small hole, which should be the secret passage.

"It's too small to know if I'll be able to get through. Zhang Ze was a little worried, he was afraid that if he got stuck in the middle after entering, he could neither advance nor retreat, wouldn't he be dead?

"Rest assured, the system has been measured, and the width of the main channel is suitable for the host's body type, and it can definitely pass. ”

After listening to the system's words, Zhang Ze was a little relieved, and then plunged into the passage.

Because the water in the Blood Demon Pool came out of here, the impact of the water in the passage was very strong, making Zhang Ze's speed very slow, Zhang Ze gritted his teeth and swam forward against the huge water pressure.

"System, how long will it take to get out!?" Zhang Ze felt that the power of his potential was constantly fading, but there was no exit ahead, and he couldn't help but become anxious.

The system replied, "There is still about five kilometers ahead to reach an inflection point, and then, the passage is easy to go, and the host can go out as long as it floats." ”

"What! Five thousand meters!" Zhang Ze almost spewed out in one breath, he can still hold on to a few hundred meters at most now, let him continue to swim five thousand meters, isn't this nonsense?

"System, why didn't you say earlier that this tunnel is so long!?" Zhang Ze was about to collapse.

The system said aggrievedly: "Host, this system has already reminded you that you can't last until the end with your lung capacity!"

Zhang Ze gritted his teeth helplessly, since he had come here, he couldn't turn back, and he couldn't turn back, so he could only continue to grit his teeth and persevere!

So he used all his strength to start swimming frantically forward, hoping to swim out of the water at the last moment and escape.

But he overestimated his ability, he was now at the end of his crossbow, and the strength of his body was being drained little by little, and his breathing became more and more difficult, and it was as if a huge stone had pressed on his chest!
