Thinking of this, the halberd in Wuran's hand danced faster and faster, and finally slammed into the ground, bursting out a big pit.

Some sat on the ground panting, thinking about how to do it.

"Light, heavy"

"Light, heavy"

Wuran muttered in a low voice, thinking about the meaning of these two words.

Suddenly, he saw a mass of ants on the ground dragging a small snake, slowly moving towards the ant nest, and a flash of inspiration flashed in his head.

"Light and heavy are just the definition of the weight of objects by humans, ants can carry things dozens or even hundreds of times larger than their own volume and weight, ordinary people can't do it, what is the reason?" Wu Ran frowned, and there was a flash of inspiration in his head, and he couldn't grasp it.

"Is it a difference in weight or a difference in definition, if the definition is different" Wu Ran sat cross-legged on the ground, emitting a dazzling white light from his body, but he didn't know, and his mind was precipitated in this question.

A whirlpool appeared out of thin air above Wuran's head, and a trace of pure white energy surged towards the whirlpool, and the purple stone in the heart of his body rotated rapidly, releasing pure energy that swirled in Wuran's body, and Wuran's cultivation actually began to grow, and the momentum on his body became stronger and stronger.

'Bang', which had naturally grown to the peak of the first rank of martial arts after these days, broke through to the second rank of martial arts under the impact of pure energy, and continued to grow slowly.

All this happened, at this time Wu Ran was not clear, he suddenly appeared in a dark room, only a little light not far away.

Wu Ran was a little curious, he didn't know why he suddenly appeared here, whether it was a fantasy or something else, but he still walked towards the light.

When he walked to the light, he saw two things on the ground, a stone several times larger than a person, I don't know what kind of ore it was, it didn't look light, and a feather that shone with golden light, and the light was emitted by this golden feather.

Wu Ran looked at the two things in front of him, and didn't dare to touch them easily, who knows what kind of place this is, if something happens, Wu Ran has no place to shout.

Wu Ran looked at it for a while, didn't find anything special, turned his head to look at the dark space, as if he wanted to find a way out, the Panlong Conference was about to start, if he was trapped in this ghost place, it would be helpless.

Wu Ran walked in one direction, and he couldn't use any True Qi here, so Wu Ran could only walk in one direction step by step.

After walking for most of the day, Wuran suddenly found something that made him speechless, there was still light behind him, and it was still very close, so Wuran had to return to the light and reach out to stroke the big stone.

"The normal way is that you can't get out, it seems that the key is still on these two things" Feeling the texture of the ore in his hand, Wu Ran's voice was a little low.

"Hey, what's going on?" Wu Ran leaned lightly on the stone, the stone actually moved back a little, Wu Ran reached out and began to push the stone hard, the stone was actually pushed away like light cotton, and floated in the air for a while, Wu Ran felt strange in his heart, he couldn't use true qi here, and he himself could be sure that he didn't use true qi, stroking the stone, and feeling the touch of the exclusive ore on the stone again.

Wu Ran walked to the golden feather, stretched out his hand to pick up the feather, and fell to the ground with a clatter, and the feather that he thought could be easily picked up did not move at all.

"What's going on, the things that were originally in my impression are so light, but the heavy things are so light, does it subvert common sense?" There was some enlightenment in my heart.

"What is light and what is heavy, and how is the weight measured?" Wu Ran pondered, the answer was a little faint, but he just couldn't lift the veil.

Stroking the soft feathers of the feathers, he thought quietly, as if he knew why he had suddenly come to this strange space.

"Epiphany, light as heavy, light and heavy" Wu Ran muttered in a low voice, and suddenly raised his eyes to look at the feather and stone, he seemed to understand.

Both hands grabbed the two objects at the same time, and the feather, which was originally very heavy, was actually caught, and the expression of the wind was indifferent, as if to say that this feather was really the feather in the mortal world.

"Sure enough, it's up to the person to decide, it seems to be heavy and not heavy, it seems to be light and not light, the way of light and heavy, haha" Even with the mind of Wuran, he can't hide his joy, which shows how important the way of light and heavy is to Wuran.

With the way of weight, Wuran's 'Ba Wushuang' can be regarded as complete, and he is more sure.

By the time he comprehended the way of gravity, he had already returned to the real world, and the body sitting cross-legged was in a mess, the courtyard that was originally quite beautiful had already been in shambles, and the house had collapsed, if it weren't for the four walls and doors still hanging, Wu Ran would definitely think that someone had come to destroy it.

Wu Ran stood up, stretched, and suddenly felt that something was wrong with his body.

"This" Wu Ran couldn't believe that he had already reached the fourth rank of martial arts, first surprised, and then anxious and worried appeared on his face.

"I don't know how long it has been, I hope the Panlong Conference hasn't started yet" Wu Ran didn't bother to tidy up his somewhat crumpled clothes, and ran towards the competition ring of the Panlong Conference in the city

At this time, the ring was full of people, the Praetorian Guards were maintaining order, and in the sky above the giant ring, an old man like an immortal sat on a magic weapon like a cloud, holding a teacup and looking at the crowd below, his face was expressionless, he couldn't see sorrow and joy, and there were two people standing beside him, one was Murong Aotian, the monarch of the Aolong Empire, and the other was a middle-aged man in a cyan robe, helping the old man carry the tea tray.

"One Thousand Three Hundred and Eighty-One Xiao Jing Tengsheng"

The fierce competition in the ring finally ended, and a man with long hair and waist in a purple robe stood on the stage in disheveled clothes, and his breath was quite steady.

The man named Xiao Jingteng saluted into the air and jumped off the stage.

"In the next battle, the Wuran of the 1,000th will fight the 980th Sun Youcai," said the middle-aged man dressed in green throws.

A round little fat man climbed into the ring in a hurry, with a round face with a little honesty, which looked harmless, but those black eyes were smart, coupled with the momentum of a martial artist's five grades, which was not to be underestimated.

"Whether the Wuran of the Thousand Numbers has arrived, please come to the stage"

After waiting for a few minutes, no one appeared on the opposite side of Sun Youcai, and the young man in Tsing Yi spoke out again.

The audience was boiling and booing, thinking that this person called Wuran must not dare to come, after all, the martial artist Wupin is also a few masters among the teenagers.

"I announce that Wuran's qualification will be ,,,,,," The young man waited for a few more minutes, and was interrupted when he saw that there was still no one on stage and was about to cancel Wuran's qualification.

"Wuran is here!"
