The location of the natural cave is still relatively hidden, in a big mountain behind He Changming's school.

This is a mountain town full of majestic mountains, and this natural cave is deep in an undeveloped mountain forest.

He Changming prepared a lot of things according to Shan Hongzi's instructions, but he was afraid that this snake demon was profound, and he had some means to save his life.

If you can subdue this snake demon, it will naturally be excellent, He Changming is still thinking about the treasure of the hundred-year-old snake demon!

I saw that He Changming peeled off the withered grass at the entrance of the cave, there was some thickness, and it was estimated that this snake demon hibernated after swallowing those souls, and he had not come out of the cave so far.

He Changming first pasted a layer of breath charm on his body, and then carefully climbed down the natural cave.

Don't look at the entrance of this cave, but there is a cave inside, Zhong Cui stone milk is hung on the wall, and there is an underground dark river surging on the side, sparkling, like the palace of the dragon king.

After this huge platform, you can see large and small holes in the wall everywhere, and I don't know where it leads, but it is very deep, and it is creepy to look at.

He Changming opened his heavenly eye, and saw that the black qi was very terrifying, filling the entire cave.

"Master, this snake demon has created a lot of killing, such a strong energy, enough for it to be struck by lightning a few times!"

He Changming sighed at this strength while looking for the source of the strength.

"That's not it, I'm the first time I've seen such a strong energy, it's really terrifying, and when the snake demon wakes up in the summer, I don't know how many creatures will be harmed."

If it is a demon clan that only absorbs the essence of the sun and the moon, although it can't get rid of its own demonic energy, it can be regarded as pure qi, as long as it is a good life and cultivation to withstand the heavenly calamity, it is not impossible to soar.

But the demon race's cultivation is miserable, not only to fight against the pursuit from natural enemies and the survival of the fittest by nature, but also to be careful of the killing of humans, the cultivation is very difficult, and it is not as fast as the human race.

Therefore, there are some demon clans who are unwilling to cultivate asceticism and have crooked hearts, just like the evil cultivators in human beings, and have taken extreme paths.

The strength of this snake demon has to cover up its own demonic energy, but you can imagine how many sins it has committed to make it terrifying!

Such a demon cultivator, at a glance, knows that he is not a kind-hearted and kind-hearted person, but a demon who kills.

He Changming finally found the source in those powerful qi, and as he searched all the way to the past, he walked into one of the caves in the cave.

This cave is getting smaller and smaller, and when it comes to the end, He Changming is already bent over, looking inside from the entrance of the cave, it is pitch black, and he can't see anything.

But the terrifying aura hit with the entrance of the cave, and He Changming's clothes floated up.

The fishy smell made He Changming almost want to vomit, it seemed that it was the snake demon inside.

"Ding, trigger the reward and punishment task, two hundred years of snake demon, repeated offenders, three stars for sin, sentenced to eighteen layers of hell, task rewards: Qi into the body, Tianyan level three, five light thunder prison trick!"

All the functions in the system are level nine, and He Changming's Tianyan can see through the flow of resentment and strength with the second level, and he doesn't know how powerful it will be when he reaches the third level.

And the introduction of qi into the body is to refine qi, which is what Shan Hongzi calls cultivation!

It's this five-light thunder prison trick, listening to the name so domineering, it won't be bad if you think about it.

The reward for this mission is huge, and it seems that this snake is not easy to deal with.

The rewards of system tasks have always been linked to the difficulty of the task, and this time there are so many rewards at once, and they are all high-end goods, He Changming wants to quit and go to his feet as if he has grown in a cave.

"Master, can this snake spirit eat it? Silly Lori's reward this time is a bit rich! ”

At this time, the cave full of ugliness was about to shine with golden light in He Changming's eyes!

Shan Hongzi pondered for a while before he said: "The front gang must be just right, I have to think of a way!" ”

As soon as He Changming heard this, he knew in his heart that there was a drama in this mission, and if Shan Hongzi didn't have any way, he would definitely not say such a thing.

"In this way, you first arrange it in the cave tunnel, there is a method of surrender in my Xiaoshan Temple, which does a lot of damage to the powerful demon and evil, and your five thunder method is a method to overcome the demon and evil, and with the cooperation of it, it should not be a big problem to take down this snake demon!"

Saying that, Shan Hongzi informed He Changming of the method of surrender, but fortunately, when He Changming came back, he had already prepared those runes and cinnabar at home according to Shan Hongzi's requirements, which could be regarded as handy.

The method of surrender that Shan Hongzi said is called the Yang Transformation and Yin Charm, and its principle is to use the Yang Qi of the charm to suppress the evil Yin and evil Qi, and the 7749 chapter rune paper can be combined into a small Zhou Tian Yang Transformation Array, intertwining the chains formed by the Yang Qi to form a bondage.

As long as the snake demon rushes into this formation and is bound by the formation, He Changming can use the Five Thunder Method to attack it unprepared and subdue this snake demon.

After everything was ready, He Changming tore off the breath charm on his body.

In an instant, two green eyes appeared in the black hole, staring coldly at He Changming.

The snake demon, which has only been two hundred years old, has not yet cultivated into a human form, although it has opened its spiritual wisdom, after all, it is still like a beast, spit out a long snake letter, and did not rush forward.

It was the first time He Changming had such close contact with a beast, although it was winter, he was also in a cold sweat, and his legs and feet were a little weak.

But as soon as he thought of the rich system rewards, He Changming plucked up his courage again, swallowed a mouthful of saliva, and walked to the entrance of the cave.

The snake demon looked at the small human in front of him, his cold eyes and pupils dilated, and he didn't know what he was thinking.

As He Changming got closer and closer, the snake demon suddenly moved!

It was so fast that in the blink of an eye, it got to the hole on its own.

"I'm rubbing, it's a bouncing snake!"

He Changming couldn't help but burst into a foul mouth, if you don't play like this, where is there a snake with such a fast speed

Of course, at the same time as the foul mouth, He Changming had already opened his legs and rushed out of the hole.

On the first floor of the refining body, he was like a human-shaped cannonball, and he rushed out with a "whoosh".

What Shan Hongzi said is not wrong, if it weren't for He Changming's body refining, he really wouldn't be able to outrun this snake demon!

However, the speed of the snake demon is not slow, that is, the distance between the front and rear feet, He Changming ran out of the hole, and so did the snake demon.

"Explode me!"

At the same time as the snake demon poked out his head, He Changming pinched the magic trick and activated Xiao Zhou Tianyang's turning array.

I saw countless fires lighting up from the long passage blocked by the snake demon's body, and the snake demon also screamed miserably.

"It's now, stinky boy, do it!"

A thunderbolt condensed in He Changming's hand, and in the next second, it slapped on the snake demon's heavenly spirit bone......
