This waterhole didn't look big on the surface, but it was actually hundreds of zhang deep, and Han Fei and Su Mengli had been diving for a stick of incense before they reached the bottom of the water.

When I got to the bottom of the pool, I was stunned by the scene in front of me, there was actually a huge mountain gate here, obviously the light under the water should be dim, but this mountain gate emitted a faint fluorescence, which illuminated everything at the bottom of the pool clearly, and the aura here was also very strong, it was estimated that it was not weaker than the cultivation holy land of those big sects, Han Fei absorbed it a little, and the mana in his body actually rose a little, although it was only a trace, but it could catch up with Han Fei's cultivation for a day.

"Be careful!"

Just when Han Fei wanted to take a closer look at this gate, he suddenly felt a dark arrow coming towards him, and before he had time to think, his body instinctively moved a small step to the left, and a powerful water arrow grazed past him, and the water arrow actually contained poison, corroding his Dao potential barrier a little, and in an instant, water pressed in, Han Fei hurriedly cast a Dao potential barrier again.

"Are you okay, right? It's that demon beast, it should be a demon beast of the way of water, the poison is naturally self-contained, there is no Dao meaning in it, but this poison is not simple!" Su Mengli breathed a sigh of relief when she saw that Han Fei was fine, that demon beast would actually hide herself, and the sneak attack Dao technique it issued was also so powerful.

"It's okay, it's hiding so well, looking at its reaction like this, it should be the period of spiritual silence, Mengli, wait for me to attract it out, you take the opportunity to break his concealment method, and then we will join forces to encircle and suppress it!" Han Fei whispered.

Han Fei was already strange, obviously Su Mengli felt a momentum below, but they didn't find any demon beasts all the way down, it turned out that this demon beast would also hide the method, no matter how dark it was, they were in the light, so it would be extremely unfavorable to them, the speed of this water arrow was very fast, if it weren't for Su Mengli's timely reminder and Han Fei's reaction was also very fast, he almost fell on the road.

"Yes, but you have to be careful, this demon beast has a very high intelligence, I'm afraid it won't show up easily, and once it appears, it will definitely be sure that you will be killed. Su Mengli did not refuse, and replied in a low voice. Han Fei was only tempted, if Han Fei was asked to deal with that demon beast directly, it would definitely not be pleased, but if it was just tempted, it should still be no problem.

Han Fei nodded, and shot directly in the direction where the water arrow came from just now, don't look at Han Fei Although he is only in the early stage of the heart move, he has several Dao in his body, if he releases all the Dao potential, the momentum is not weaker than that in the late stage of the heart move, but Su Mengli is here, he is not good at performing, he can only quietly use the Dao potential barrier to protect it.

In fact, he is not without means to deal with the Spiritual Silence Period, don't forget that he still has a stack of Dao Talismans in his Qiankun bag, the strongest of which is the Seventh Grade, which can just deal with the Spiritual Silence Period.

Han Fei didn't have much space in front of him, and the bottom of the pool was not big, but Han Fei had a feeling that the demon beast should still be around here, although it didn't have to be launched from in front of him to cast the Dao technique, but with the spirit of this demon beast, it didn't have that kind of scheming, and not every Dao technique could be cast in any direction like the wind and clouds, so he judged that the demon beast was here.

Han Fei first stirred the sewer with the wind and clouds in the water, because the pressure here was too great and it didn't have much effect, and it was in the water, the way of the wind was already very weak here, and it was difficult to exert its true power.

Han Fei was a little helpless, so he could only seduce by deliberately revealing flaws. First pretended to make a few more attacks, and then turned angrily and floated towards Su Mengli.

Su Mengli's side also pretended to attack everywhere, her poisonous way was not suppressed much in this water, but because of the divergence of the water, the attack increased a little, but she also deliberately reduced her power and maintained it at the level of the early stage of spiritual silence.

Just when Han Fei was about to reach Su Mengli's side, an invisible fluctuation hit him, this fluctuation was very weak, and even Su Mengli didn't notice it at the first time, and Han Fei was waiting for this moment, he gathered almost all the Dao momentum behind his back, at this time, it was like having eyes behind him, he quickly turned around, first sideways to avoid the invisible fluctuation Dao technique, and then hit a long wind and wave with lightning speed, although the power was still insufficient, only hitting the invisible demon beast, but it was enough.

Su Mengli was only stunned for a moment, and then a poisonous snake-like Dao technique burst out, the originally invisible demon beast didn't have time to react at all, it didn't know why Han Fei could dodge such a silent attack, and was about to find out its location, a poisonous snake appeared in front of him and bit at it, and the attack power of the poisonous snake was extremely strong, and it bit through the skin of this demon beast in an instant, making it poisoned, and its color became a little black.

Only then did Han Fei and the others clearly see the appearance of the demon beast that attacked him, this was a fish demon, no different from an ordinary carp, but the body was transparent, and its mouth was full of sharp teeth, and its body was not too big, only slightly larger than a human.

The fish demon struggled to resist the toxin with his mana, and seeing that the color began to fade again, Han Fei hurriedly took out a seven-rank Dao talisman - Water Dragon Binding and threw it at the fish demon.

And Su Mengli was not idle, this was a demon beast in the middle of spiritual silence, and in its several favorable waters, it had to be killed quickly, and a few poisonous stingers were nailed towards the fish demon.

Su Mengli is in the late stage of spiritual silence, the way of poison has several true intentions, of course her attack is much stronger, Han Fei's water dragon binding only entangled the fish demon for a few seconds, and it was about to be broken, but Su Mengli's stinger was fiercely nailed into the fish demon's head, the fish demon suddenly had a painful expression, swinging his tail wildly, and bursts of mana rushed towards Han Fei and the two, Han Fei didn't make a move, his barrier couldn't resist the attack of the middle stage of spiritual silence, but Su Mengli cast a poisonous gas shield to block the front.

Although the fish demon struggled hard, the more the toxin struggled, the faster it eroded, and it didn't take long for the fish demon's brain to invade, and then the fish demon stopped struggling, because its brain was completely rotted away as soon as it was invaded, because of the slight transparency of its body, Han Fei could see it clearly, and he didn't feel goosebumps, the way of poison was really ruthless.

His poisonous way is still very weak, it is estimated that he can only poison the level of alien beasts, demon beasts can be completely resisted, and what he comprehends is still eroding life spiritual power, even if he encounters a strange beast with strong body energy, it will take a long time to poison him.

Han Fei swam over and cut off the head of the fish demon, and then carefully pulled out the fish demon's Dao core, the water dao core, the fish demon's attack just now was obvious, and the back should be the invisible true meaning of water, he hadn't comprehended it yet, but he had already remembered the subtlety of the attack just now, and he might have gained something when he went back to study it.
