Damn, just do it! The king of Yanshan suddenly saw a huge golden fist shadow coming towards his face. In a hurry, he pinched the demon duel, and the thick demonic qi immediately formed several barriers in front of him.

Between the lightning and flint, the golden fist shadow crashed into the barrier of demonic power condensed by the King of Yanshan. With a bang, these several demonic power barriers were pierced one by one by the Thunder Collapse Fist. Then, the barely weakened fist shadow struck the Yanshan King in the face.

With a miserable scream, the king of Yanshan was directly hit by the powerful fist shadow and flew out, and slammed straight into the mountain wall.

Boom, the huge impact force even knocked out a big hole on the mountain wall, and the body of the king of Yanshan was also buried by scattered stones.

The little fox demon and stone monster who were watching the battle from the sidelines were dumbfounded, and they couldn't believe what was happening in front of them.

Hey, is this the end? Li Xi looked at his fist in surprise, then at the pile of stones, and said to himself: "Does this boss seem to be a little weak!"

As soon as the words fell, the pile of rocks exploded violently, and a black smoke came out of it, and the King of Yanshan reappeared in front of Li Xi.

I saw that his face was hideous, but one side of his face was obviously sunken, and he looked very embarrassed.

The King of Yanshan stared at Li Xi with murderous intent, and shouted angrily: "Little thief, since you are looking for death, I will fulfill you!"

As he spoke, the King of Yanshan slapped his hands on the ground and shouted: "Poison Curse!"

I saw several black poisonous smoke with a diameter of more than one meter rising from the ground out of thin air, and rushed towards Li Xi in the distance with a roar. This strip of black smoke was extremely fast, and all the flowers and trees withered in the area it passed, and some dry tree trunks were all turned into powder, obviously the black smoke contained a fierce poison.

Looking at the billowing black smoke that came quickly, Li Xi's face changed greatly.

He threw a punch at the poisonous smoke, only to see a golden fist shadow rushing into the black smoke, and with a bang, the black smoke was dispersed in an instant. But it didn't take long for the scattered black smoke to gather again and continue to rush towards Li Xi.

"Hahaha, my poisonous smoke is formless, it can't be dispersed, it can't be beaten, it contains highly poisonous, once it is stained, it will continue to corrode your flesh and bones, making you worse than dead until you die. King Yanshan laughed wildly.

Damn, there's still this kind of operation. It seems that the Thunder Collapse Fist is useless against the poisonous smoke, at most delay a little time, this time it is estimated that I will be more than lucky. Li Xi was secretly anxious in his heart.

In the blink of an eye, a poisonous smoke was about to hit Li Xi, and he hurriedly threw himself on the ground and fell into a dog eating. The poisonous smoke could be wiped over his back, and Li Xi only felt that his back was cold. At the touch of it, the clothes behind the back have been corroded by poisonous smoke.

Dizzy, this poisonous smoke is so corrosive, what should I do, what else can I do? Li Xi's brain was running rapidly, but after thinking about it, it seemed that he would only have one thunder crash fist, damn it, fight!

Li Xi stood still with his feet, facing dozens of billowing black smoke, he shouted: "Thunder Crash Meteor Fist!"

I saw Li Xi's fists swinging out like a motor, and each punch had a golden fist shadow striking out. The continuous fist shadows even formed a huge light curtain in front of Li Xi.

Dozens of thick black smoke continued to bombard the light curtain in front of Li Xi, but they were constantly dispersed and regrouped, hitting again. But there was not a single black smoke that passed through the light curtain and hit Li Xi's body.

The King of Yanshan was stunned in surprise when he watched Li Xi's fierce operation.

The little fox demon also covered her mouth in surprise when she saw this, of course, she also hoped that Li Xi could defeat the mountain demon and help her regain her freedom.

The stone monster shed tears of pain, and it seemed that the taste of the Thunder Crash Meteor Fist made him unforgettable.

"This style of play is very draining, I see how long you can hold on?" Saying that, the King of Yanshan also increased the output of demonic power, striving to break through Li Xi's defense in one fell swoop and put him to death.

But gradually, King Yanshan felt that something was wrong. Obviously felt that Li Xi's Yuan Force was about to dry up, but suddenly he became full of vitality again, and the dragon and tiger leaped. This TM is unscientific, how can Li Xi be like a little strong who can't be killed, his vitality is endless, and he can't use it endlessly. If he continues like this, his own demonic power will be exhausted.

The King of Yanshan stared at Li Xi suspiciously, and suddenly saw that just when his vitality was about to run out, a small pill was conjured out of thin air in his left hand, and he knocked it into his mouth, and immediately recovered his vitality.

The King of Yanshan immediately shouted angrily at Li Xi: "I'll wipe it, you want to be shameless, when you fight, you still knock the elixir, and you continue to knock, don't you know what shame is!"

Li Xi shook his head helplessly and said, "You can also knock the elixir, I didn't stipulate that you can't knock it." After speaking, he snapped a mouthful, and another Qi Pill went down to his stomach.

It's really a demon who is more popular than a dead demon, where did I, a scattered demon in the poor countryside, come from? The king of Yanshan couldn't help but shed tears of grievance when he thought about it.

It is said that although Li Xi is relaxed on the surface, he is also secretly complaining in his heart, not to mention that the number of Qi Pills is getting smaller and smaller this time, even these hands are almost tired and can't lift because of the constant waving, so they can only barely support it.

However, the King of Yanshan is no better, and after maintaining the output for a long time, his demonic power is about to run out.

Just when both sides were about to hold on, the little demon fox who had been silent secretly moved behind the king of Yanshan. "Red Lotus Claw!" The little fox demon suddenly stretched out his claws containing red demon power, and grabbed it at the back of the King of Yanshan.

With a hissing sound, the back of the King of Yanshan was scratched out of five deep bone-deep, bloody paw prints. At the same time, the terrifying demonic power also rushed straight into the mountain demon's body, frantically destroying his internal organs.

"Slut, dare to sneak attack me!" King Yanshan was in pain, and angrily slapped back his palm, which happened to slap the little fox demon's chest, and the little fox demon vomited blood and retreated.

The king of Yanshan also spat out a mouthful of blood, obviously suffering a lot of internal injuries.

Taking advantage of the fact that the King of Yanshan turned back, Li Xi also rushed forward quickly. The Thunder Collapse Fist erupted with all its might, and a punch hit the chest of the King of Yanshan. Hearing only a crackling sound, the chest of the King of Yanshan was obviously sunken, and the bones in his chest were broken, and the whole person vomited blood and flew out, falling beside the stone monster.

"How are you, King?" the loyal stone monster lifted the King of Yanshan.

The King of Yanshan saw the little fox demon coming over and looked at him side by side with Li Xi. He raised his finger and pointed at the little fox demon, panting and asking, "Why are you joining forces with humans and fighting against the demon clan, don't forget that you are also a demon!"

The little fox demon looked at the king of Yanshan hatefully, and said angrily: "I was at ease in the world, but you imprisoned me, controlled my demon pill, and asked me to help you do something hurtful to the heavens and reason, how can I not hate you! Quickly hand over my demon pill, I can spare you from death, otherwise you will die today." ”

After hearing this, the king of Yanshan laughed angrily: "Haha, very good, you are very good!" The laughter was full of anger.

Could it be that today is my last day? The king of Yanshan thought sadly and indignantly in his heart, no, I am not reconciled. It took 10,000 years for Dayan Mountain to give birth to my mountain soul, and I worked hard to cultivate for nearly a thousand years to have today's realm. I will not be willing to die here, and I will drag you to be buried with me!

I saw that the king of Yanshan suddenly turned over, grabbed the top of the head of the stone demon beside him, and roared wildly: "Stone monster, borrow your demon soul today to help me recover my strength and break through the realm!"

After speaking, the demon soul and demonic power of the stone monster were continuously absorbed into the body of the King of Yanshan.

"Don't, the king spares his life!" The stone monster struggled desperately, but its own realm was lower than that of the king of Yanshan, and he was seriously injured, so he gradually lost his movement.

With the absorption of the stone monster demon soul and demon power, the momentum of the King of Yanshan skyrocketed, and his already tall figure bulged as if he was inflated. He couldn't help but look up to the sky and roar, only to hear the bang, and the king of Yanshan revealed his true body.

I saw that it was covered with black hair, with dark and sharp nails growing on its hands and feet, its entire face was also covered with black hair, and long fangs grew out of its mouth. It gulped and breathed, drooling down the corners of its mouth and dripping on the ground.

Li Xi gasped when he saw it, isn't this a template of a black bear spirit.

Could this be the game's regular routine, the second transformation of the boss? Li Xi thought blankly.
