Black Dragon has lived for thousands of years and is more sensitive to danger than any life.

However, because I am strong enough, there is no natural enemy here that is powerful enough to threaten its life.

So even if it has a keen perception of crisis, it has been too many years since it has not encountered such a crisis.

But for the Black Dragon who wants to cultivate to become a true dragon, a comfortable life did not make him slow, but instead made him more and more smart.

It attaches great importance to its own life. Without life, what else can it talk about evolution into a real dragon?

When he noticed the danger, the Black Dragon exerted his strength to the extreme, not to counterattack Chu Nan, but to escape.

At this time, what anger and dignity are passing by, compared to life.

If you want to become a true dragon, you should not be afraid, but you should definitely cherish your life.

Especially at the critical moment when I have been practicing for thousands of years and have been successful for more than half of my life, the more I have to put my life first.

If you die, everything will be gone.

As for the loss I suffered in Chu Nan today, it is nothing compared to my thousand-year practice.

At worst, you can take revenge in the future. As long as you practice to become a real dragon, are you still afraid that you can't deal with Chu Nan?

The black dragon was desperately trying to escape, but how could Chu Nan let it escape at such a critical moment?

The underground river is turbid, making Chu Nan's perception unable to be easily used.

The black dragon has lived here for thousands of years. Letting it enter the water is like a tiger adding wings. It can always have a way to get rid of its own tracking.

By that time, the system's tasks will not be completed.

Although the task of killing the two black and white dragons is not a forced task, it is not said that it will be killed once it is not successful.

But that gift package for cultivating immortals made Chu Nan covet for a long time.

So Chu Nan knew that it was now a time when it was related to his major interests. No matter what, Hei Jiao could not just escape from his nose.

So, Chu Nan also madly activated his internal energy, increasing his strength and speed to the extreme.

This blow must be the life of the black dragon!

The black dragon escaped faster, and Chu Nan attacked faster.

The next moment, the nine-section whip in Chu Nan's hand was pierced at the seven-inch position of the black dragon.

The sharp position of the whip directly hit a piece of coin-sized flesh-colored scales at the seven-inch position.

Puchi!

The nine-section whip pierced into the black dragon's body like cutting tofu.

The black dragon also stiffened all over, his body shook violently, and he was no longer under control.

It was obviously hit hard.

Chu Nan had experience in slaughtering the white dragon and knew that the worms were growing here, and the seven-inch position was the weakest area.

As long as they have not evolved into real dragons, they will be more like snakes.

The saying of hitting a snake and hitting a seven-inch is also applicable when hitting a dragon.

As for where the seven-inch position of the dragon is, it is easy to identify. It is magnified at the same multiple according to the seven-inch position of the ordinary snake.

Because the dragon has been practicing for enough years, it is very tough to practice even at the seven-inch position.

The seven inches of a dragon can make it feel pain and even hurt it, but it is not enough to make it die.

To truly kill the dragon, you still have to find the reverse scale, which is a weak area at a seven-inch position.

The black dragon was all black, with only seven inches of flesh-colored scales, so Chu Nan could tell at a glance that it was the dragon's reverse scales, so he stabbed the nine-section whip in without hesitation.

Judging from the unstoppable feel when the whip was stabbed in just now, and the reaction of the dragon struggling after being stabbed, Chu Nan has found the right place.

Even the reason why the dragon noticed the crisis at a critical moment was because Chu Nan aimed at its reverse scale.

A dragon has reverse scales and dies when touched.

This sentence has two meanings. One means that the dragon's reverse scale cannot be touched. Once it is touched, it will think that you are going to hurt its life and will kill you without hesitation.

Another meaning is that if you hurt the dragon's reverse scale, the dragon will die.

Even the dragon's reverse scale position is so fragile, it is naturally even worse than that of a dragon.

Soon, after a two or three-meter-long nine-section whip was pierced into the reverse scale, the dragon suddenly fell rapidly like a deflated ball.

This time, Chu Nan did not control the dragon's body to fall, and let it fall to the bottom of the underground river where the water was drained.

Anyway, the black dragon is almost dead now, so there is no need to fight with it in the mud at the bottom of the river. If it wants to go down to take a bath, then let it go.

After falling into the mud, the black dragon's body struggled and slapped hard like a loach roasted on the fire.

Although he clearly felt that the black dragon was not far from death, Chu Nan did not want any accidents at this critical moment, so he flew down for a while and waited for the black dragon to die at a high place twenty or thirty meters away from the mud.

The black dragon struggled before his death and the mud was swept across the sky.

However, Chu Nan is separated by an internal air defense cover, so he is not afraid of getting dirty clothes.

A few minutes later, the black dragon rolled less and less, and finally it turned into the mud like a dead person.

At the same time, the Heavenly Dao system that has not bubbling for a long time finally came new movements.

"Did, congratulations to the host, complete the system hidden task "Slaying the Double Dragon", rewarding merit value..."

After hearing the Tiandao system prompted to complete the task, Chu Nan did not listen carefully to the following content.

Anyway, the mission is completed, the rewards will not be able to fly. When will you finish your work? Let’s learn more about it and be excited.

The most urgent task is to clean up the black dragon's corpse as soon as possible, and then go outside to find Feng Yao and Liu Mingyan to report their safety.

The fierce battle with Hei Jiao just now made such a big noise, I am afraid that the two women will be frightened at this moment.

If they don’t go out, they will know that they are still alive, and maybe they will all get sick in a hurry.

The thought of cleaning up the black dragon's corpse gave Chu Nan a headache.

If it weren't for the fact that this guy's body was full of treasures, Chu Nan would really not want to pay attention to it.

After all, it has been rolling in the mud for so long, and there is no clean area on its body.

But God finally encountered a black dragon that was about to become a true dragon in this world of scarce supplies. If it was too dirty and would not take away all the useful things, Chu Nan would not forgive himself.

After struggling for a while, Chu Nan soon had an idea.

He reached out to grab the black dragon in the mud, and the huge body of the black dragon floated in the air.

At the same time, Chu Nan himself soared into the sky, flew over the height of the river, and waved his hand at the place that blocked the water surface on both sides. The inner air wall that blocked the water surface and made the bottom of the river become a land, and immediately disappeared.

Without the barrier of the inner air wall, the water that had grown to hundreds of meters high fell down in a bang.

At this time, the black dragon's corpse was floating just halfway from the center of the river.

The huge water flow suddenly hit the black dragon like a big waterfall.

However, because of the fixation of Chu Nan's internal energy, the Black Dragon's body was not shaken at all, no matter how the water flow impacted.

With the waterfall-like water flow, the black dragon's corpse was washed cleanly, which was even more convenient than automatic car washing.

When the water of the underground river continued to rush forward at a normal flow rate, Chu Nan raised his hand to suck the black dragon's body out of the water.

Without the pollution of the silt, Chu Nan was in a much better mood and finally could do the finishing work with peace of mind.

Soon, Chu Nan was flying in the air, removing the black dragon's skin, inner elixir, and even the horns.

The entire process is completed in the air without any support.

If you want to do this, you will definitely not be able to bear it.

But Chu Nan's internal energy is inexhaustible, and he can be willful in order to love cleanliness!
Chapter completed!
