The Black Charm Mouse is a ferocious demon that lives in the dark and damp, with sharp fangs that can suck blood, and its skin characteristics allow it to blend perfectly into the darkness to capture its prey, which is extremely fast and very tricky.

Tang Yu couldn't have imagined that he was going to face this kind of monster, the most terrifying thing at the moment was that the Black Charm Rat King was also dispatched, and the speed at which it moved in the darkness was about the same level as the second grade!

This can be said to be the strongest creature Tang Yu has encountered so far, and Tang Yu is currently able to rejoice that the devouring bat rioted because of the black charm rat pouring out of the nest, and the two sides are entangled with each other, which makes Tang Yu's current pressure suddenly reduce a lot.

In the face of the frenzied pursuit of the black phantom rat group, what Tang Yu can do at present is to pull out the brightness of his immortal qi to the maximum, so that the light can shine farther away, the dazzling light can slow down the movement speed of the black phantom mouse, but this is not a long-term solution, she must be caught up by the black phantom rat, rushed to the vicinity of the underground river to be able to avoid danger.

While Tang Yu was running desperately, he didn't forget to complain on the road: "What a big mouse, what about the second grade, heads-up!"

Of course, it's impossible to go head-to-head, and the black squirrel will never fight alone with its prey.

The huge movement made by the black charm rat woke up the Pole Devouring Bat King sleeping in another underground hollow, and while it spread its huge wings, it also sent a signal to its companions, and the Pole Devouring Bat also had a posture of pouring out of the nest after receiving the order, and rushed towards Tang Yu from various large and small holes.

After Tang Yu perfectly blended into a wisp of divine wind, he was far more sensitive to wind currents than before, and learned that a large number of pole-devouring bats were rushing here, if the two sides could be completely mixed together, Tang Yu would have hope to get out safely, but before that, Tang Yu would have to hold on for a while.

Tang Yu saw that the Black Charm Rat King was about to catch up with him, so he had no choice but to be forced to fight back, only to see that she completely unleashed the Ruyi Narcissus Method, summoning all the water that could be mobilized into layers of turbulent waves, and mercilessly rushed towards the group of black charm rats that were chasing after her!

Although the waves are turbulent, they don't seem to be effective when used to deal with the black phantom rats, they will melt into the darkness in the face of danger, and when the waves pass, they will rush out of the darkness again, Tang Yu's waves can't cause much damage to them, not to mention, even the speed has not slowed down much, Tang Yu's long-term reliance on the water element, actually lost its effect at this time.

"It's hard now...."

Tang Yu was helpless to gather the immortal qi under his feet, and once again quickened his pace and ran in the direction of the underground river.

"I'll hide in the water and see what you can do with me!"

If you can't fight, you can run, but you can run hard, run to death, Tang Yu has run away so hard for the first time since he was born, the small steel plate of the black succubus, Tang Yu currently has no means of checks and balances, and it is difficult to kick over.

Finally, under Tang Yu's extreme speed, she finally came to the underground river that was in her own sense!

It's just that the water of this underground river is a little strange, it is black!

However, at the critical moment, Tang Yu didn't bother to care if he was special or not, and plunged directly into the Heishui River, and the Black Charm Rat King who followed saw this scene and quickly stopped moving forward, stopped at the periphery of the Heishui River, staring at the direction of Tang Yu's falling into the water, it was afraid of the Heishui River, but it was unwilling to catch Tang Yu.

When the Black Phantom Rat King roared angrily, the Pole Devouring Bat King suddenly spread his wings from behind and flew over, and his minions pointed directly at the Black Phantom Rat King below, the two giants in the underground cavern of the dragon's head, and today they faced each other again.

I saw that the Extreme Devouring Bat King rotated his body and turned into a purple light to kill the Black Phantom Rat King, who suddenly used his ability to melt into the darkness, and skillfully dodged the first wave of attack of the Bat King, the Bat King was a little annoyed that he couldn't hit it with a single blow, and then opened its purple eyes to look around, and within a moment it locked the location where the Rat King was hiding in the dark!

The Bat King waved his claws and went directly into the darkness, and the Rat King couldn't escape and chose to be tough with him, opening his bloody mouth to the maximum, and the saliva between the upper and lower lips was drawn, and the posture was like swallowing the Bat King with one mouth!

The Bat King and the Rat King have been fighting in this dragon head for many years, and they have long been familiar with each other's attack methods, and they will never be able to win or lose until the end.

When they were inseparable, Tang Yu stretched out his little head from the Heishui River, and his two eyes quietly stared at the Bat King and the Rat King who were fighting ferociously, and when he saw that there was no monster target on himself, Tang Yu was able to breathe a sigh of relief.

Tang Yu, who had shaken off the Black Phantom Rat King, turned around and set his eyes on the other side of the Heishui River, where Tang Yu saw a glittering purple shimmer, as if there was an amethyst hidden in the ground!

Thinking of the amethyst, Tang Yu couldn't help but become excited, getting some amethyst and bringing it back meant completing another task set with Medicine Valley.

Without further ado, Tang Yu immediately swam forward, but soon Tang Yu found something not quite right, "This Heishui River is strange!"

Tang Yu wrapped her body with immortal energy, and she was half in the Heishui River at the moment, and she could clearly feel that these Heishui Rivers were eroding her immortal qi protection!

The intensity of the invasion is very strong, fortunately, Tang Yu uses immortal energy, if it is replaced with ordinary vitality, I am afraid that it will have been eroded a long time ago, this is not over, Tang Yu can turn a lot of water into his own use through the Ruyi Narcissus Method, but the water of this Heishui River is not good! Or can only control so little!

In this case, Tang Yu has encountered it for the first time!

A sense of uneasiness began to come to Tang Yu's heart, she didn't see that she was wearing the Heishui River, so naturally she didn't know what strange things were waiting for her in the river, all in all, Tang Yu had to leave the Heishui River of unknown origin immediately!

But, where can Tang Yu go?

If you try to swim to the other side, if you don't know what this black water river is, Tang Yu will feel that he is a sheep in the mouth of a tiger, and his life will be in danger!

This really made it difficult for Tang Yu, and he was in an extremely embarrassing juncture.

"I thought I would get out by jumping into the water, but how do you feel now........ I sent myself to another, more dangerous place..."
