As I said before, the demon core is a treasure that can improve the realm for martial artists, and the reason why the four major families are in the four realms is largely related to the demon core stored in their family treasury.

The demon core is the crystallization of the essence of the demon beast, the essence of the demon beast and the true qi of the warrior are common from a certain point of view, the essence in the demon core can greatly promote the activity of the warrior's body, so that those who are in a bottleneck because of advanced age can get the opportunity to break the mirror, the essence of the demon beast can also quickly replenish the energy required by the warrior when breaking the mirror, even if it is not used to break the mirror, those energies can greatly improve the accumulation of the warrior's true qi, but there are advantages and disadvantages.

Martial artists who use the demon core to break the mirror, the quality of true qi is not as good as those who use elixir to break the mirror or break the mirror independently, and the impurities in the demon core will entangle the martial artist for a lifetime, which is likely to cause the martial artist to fall into another bottleneck, this kind of thing is nothing for those older generation of martial artists whose potential has been exhausted, but it is very troublesome for a younger generation of martial artists like Bu Fan, but now Bu Fan has no choice, and if he does not improve his strength, there will be no future.

Bu Fan swallowed the demon core the size of his thumb nail in one bite, and the dark yellow demon core entered his abdomen, and he immediately urged the true qi to be refined, thanks to the memory of the mad monarch, he learned the refining method of the demon core.

At this time, the sound of something falling to the ground came from outside, and the door was split open by Bu Kick Yun, who walked in first, followed by the two Great Elders.

"Admire, admire, kick Yun Xian's nephew is really young and promising!" the Great Elder of the Wu Family praised.

Bu Kick Cloud's face darkened.

He saw the lights lit in the cave, and the faces of the two great elders were also ugly, and they smelled the breath of outsiders.

"Someone has taken the lead!" "The Great Elder of the Wu Family immediately looked at Ning Quan.

Ning Quan hurriedly denied: "I don't know anything!"

The Great Elder of the Bu Family hurriedly came over to play a round: "Brother Wu, don't worry, this aura has not yet dispersed, the other party should have just left, let's find out if there is any secret passage in this cave mansion, maybe we can catch up." ”

"Give it to me to find it!" said the Great Elder of the Wu Family to several Wu family members behind him.

In the secret room, the voice of the great elder of the Wu family faintly penetrated the outer wall, Ning Qingjun was very nervous, the smoke and fire in the secret room intensified her panic, she put her coat on her head, covered her mouth and nose, to prevent trouble caused by the smoke, the button to open the door was not difficult to find, once they found it...... Ning Qingjun hurriedly opened a stone slab behind the bookshelf, there was also a button to open the secret room, she relied on this button to get out, this button was much finer than the one outside, and it seemed that it could be locked, Ning Qingjun tried it, only to hear a creak.

"Well, there's movement over here. The Great Elder of the Bu Family pointed to the location of the secret room and said, in the end, it is the Four Realms, and the perception is too keen.

The door was indeed locked, and Ning Qingjun breathed a sigh of relief for the time being, but in this way, they would completely become turtles in the urn, and now he could only hope that Bu Fan, who had swallowed the demon core, would be able to take her out with her.

The demon core that entered the abdomen was dissolved by Bu Fan's true qi after a while, and it was supposed to wait for it to dissolve naturally, but now the situation is urgent, and I can't take care of it so much. A thick turbidity spread in Bu Fan's body, flowing into the dantian along Bu Fan's tendons and veins, and converging into the origin of true qi, and a sharp pain like the five internal organs being cut by a knife and an axe came from the dantian.

"Is it too fast?" Bu Fan endured the severe pain and meditated to speed up his digestion.

The essence quickly merged into his true qi origin, and the severe pain calmed down somewhat, but soon another trouble also came, the roar of the demon beast sounded in his heart, and the remaining consciousness in the demon core began to make trouble.

A vague pangolin shadow formed in Bu Fan's interior scene, which was an inevitable trouble when refining the demon core.

While accelerating refining, Bu Fan used dry Zen Gong to condense the monk and fight against the demon beast consciousness, fortunately, the dry Zen Gong was already focused, and the demon beast consciousness couldn't help him.

The consciousness of the pangolin demon beast gnawed on the monk transformed into the dry Zen heart seal for a while, and suddenly it turned around and its long tail suddenly became larger, pumping on the monk transformed into the dry Zen heart seal.

"Uh-huh!" Bu Fan couldn't help but snort, and a mouthful of blood spurted out of his mouth, startling Ning Qingjun.

The dry Zen monk was shaken by the tail flick of the demon beast, but fortunately, the demon beast consciousness was quiet after the tail flicking, otherwise Bu Fan might not be able to hold on, Bu Fan couldn't take care of the demon beast consciousness, and hurried up to refine.

The people outside had noticed something unusual in the chamber and began to break down the door, which was not as thick as the main door.

"Let me come!" Bu Kick Cloud said, waving the black cloud ruler in his hand.

At the moment when the door cracked, Bu Fan opened his eyes, the demon core was finally refined by him, the essence and true qi were mixed and flowing in his body, he felt an unprecedented huge power, and now even if he faced that demon beast, he had the power to fight!

The door of the secret room was broken, and Bu Fan luckily forced the smoke and fire in the secret room out of the door.

For a while, the smoke in front of the door of the secret room was filled, and the two Great Elders reacted immediately, and they were lucky to avoid the smoke, and suddenly the two of them passed through their true qi.

"I want to run when I'm dying. The Great Elder of the Wu Family immediately condensed his true qi into a big hand and grabbed it towards Bufan and them.

The restraint of the True Qi of the Four Realms greatly weakened the speed at which Bu Fan escaped, and he saw that his hand was about to be caught.

Bu Fan was in a hurry and shouted: "Kick the clouds, what does it taste like to pee!"

The sword qi broke through the air, and instantly split the true qi of the two four realms, Bu Fan took the half-treasure knife behind him to block, and the knife was split into two petals, but it was successfully blocked, and Bu Fan took the opportunity to pull Ning Qingjun out of the door opening.

"Thank you!" shouted Bufan.

Ning Quan secretly breathed a sigh of relief, his heart was almost jumping out just now.

Bu Kick Yun also knew that he had been tricked, and roared angrily: "Live target——

hurriedly chased out.

"Brother Wu, I'll leave it to you here. The Great Elder of the Bu Family said to the Great Elder of the Wu Family, and also chased him out.

The Great Elder of the Wu Family, how could he just stay like this, and after a few words, he also chased out.

Without the True Qi of the Four Realms to stop him, Bu Fan quickly rushed out of the hole, he jumped and fell towards the mountain, there was a sound of sword roaring, Bu Fan kicked the clouds and chased after him, and Bu Fan threw Ning Qingjun somewhere nearby.

"You can find a way to escape for your life!" he really didn't care.

Ning Qingjun also understood what he meant, and immediately took the method and disappeared into the mountains and forests.

Bu Fan launched the small startling steps he learned from the Mad King's memory and fled.

"Just your target, you dare to compare with me!" Bu Kick Cloud quickly chased after him.

He stepped into the air with one foot, and every step jumped farther than a step, and in the end, what he had castrated was not as good as the genuine version.

"Die!" Bu Kick Yun waved his hand, and another sword qi slashed towards Bu Fan.
