The promotion mechanism of Yuan Dan Realm is also effective for Lu Chen.

The difference is that the core of other people's promotion is Dantian, while Lu Chen is the Chaos Orb.

That is to say, once the Chaos Orb was enlarged by the real essence, Lu Chen would break through it once.

The Chaos Orb is a divine object, it can lock all the true energy, and the true energy will only increase but not decrease, which is very beneficial to Lu Chen.

Lu Chen stared at the Chaos Orb, at the space with a radius of hundreds of feet, at the real essence permeating inside, at the high and dense aura pulse wriggling, at the mountains of three-pattern aura pills, and fell into deep thought.

It is definitely not an easy task to fill the Chaos Orb with true energy. Without a huge amount of aura to transform the true energy, do you want to advance to the realm?

Wait for the turtle to climb!

The aura in the demon cave is less, and the aura is only two thousand times richer, which cannot meet his needs.

The cultivation must be on the ground, and it must be in the branch sect. The 10,000 times of aura there is the capital for his advancement!

The promotion core of Yuan Dan Realm, for others, is to fight for true essence, and for him, it is to fight for spiritual energy.

If he wanted to be promoted quickly, he probably had to use his treasured spirit energy vein.

Now Lu Chen has an idea, that is, can the dragon veins draw spiritual energy directly from the Chaos Orb?

If it can be done, the link of taking out the spiritual energy veins will be omitted, and you can even practice anytime, anywhere.

The passage between the Chaos Orb and the Dragon Vein must be opened to realize this idea.

How to get through?

The Chaos Orb is usually closed, and everything can be put in or taken out of the body, but it cannot enter the body.

Lu Chen suddenly had an idea, what if the dragon's veins entered the Chaos Orb?

Lu Chen tried it immediately, and with a thought, he drove the two dragon veins out of position.

As a result, only the Yanlong vein responded to Lu Chen, leaving the pulse position and swimming in the body.

But the Dulong vein is still young, and it cannot be separated from the pulse position.

As Lu Chen's thoughts turned, Yan Longmai swam to the Chaos Orb and successfully entered the Chaos Orb.

When the Yanlong vein entered the Chaos Orb, it was immediately attracted by the spiritual energy vein. Like a hungry dragon, it opened its mouth and frantically absorbed the high-concentration spiritual energy contained in the spiritual energy vein.

Yan Longmai draws spiritual energy while converting the spiritual energy into real essence.

It's done!

Lu Chen was overjoyed. He didn't have time to draw the spiritual energy of heaven and earth in the future, so he put the Yanlong Vein into the Chaos Orb, which also had the effect of cultivation.

But now, there is still a little spiritual energy in other places in the demon cave, so you can run over to draw it, so don't waste the resources of the spiritual energy channel.

With a thought, Lu Chen ordered Yanlongmai to stop drawing spiritual energy veins.

Yan Longmai seemed very reluctant, but it obeyed Lu Chen's will and stopped drawing the spiritual energy veins.

The Yanlong vein circled around the spiritual energy vein several times, and suddenly the longan turned and stared at the three-pattern spiritual energy pills piled up like a mountain beside it.

Roar!

With a low growl, Yan Longmai rushed towards the pile of three-pattern spiritual energy pills, and then opened his mouth, swallowing thousands of three-pattern spiritual energy pills in an instant.

"Stop, stop, stop, that's my life-saving elixir, spit it out quickly."

Lu Chen was in a hurry and quickly gave orders to Yan Longmai.

It's a pity that there is no way to spit out the elixir that has entered the dragon's stomach.

The three-pattern aura pills were all transformed into pure aura in the belly of Yanlongmai, and then transformed into strands of true energy, which were then expelled by Yanlongmai and stored in the chaotic beads.

"I'll go, without my order in the future, don't touch the pill!"

Lu Chen was a little bit crazy, and his flesh was in extreme pain.

The three-grain spiritual energy pill is not easy to make, you eat anything related to spiritual energy when you see it, and even swallowed thousands of pills in one gulp, what a prodigal.

Yan Longmai blinked, and swam in the Chaos Orb for a while, then left the Chaos Orb and returned to his pulse position.

"Well, dragon veins can swallow pills?"

Lu Chen suddenly slapped his head and remembered something, and couldn't help but become ecstatic.

That is to say, in the future, Zhantian will be sacrificed to supplement the true essence urgently. You don't need to eat the three-grain spiritual energy pill yourself, just let Yanlongmai take a bite. Anyway, you need the dragon vein to transform the true essence, and the effect will be the same!

In this way, what a time saver.

On the battlefield, time is life!

At the moment of joy, there was a faint and familiar sound from outside the cave. Someone came in, but there was no breath.

Lu Chen immediately shielded his breath, sneaked into the ground, dived to a dark corner of the cave, and poked out half of his head to see who was coming?

Not long after, a ball rolled into the cave and rolled into the cave.

The orbs looked familiar, reddish red, like a pair of shields, more like two cauldrons buckled together.

pot!

Lu Chen's eyes lit up.

Your sister, these are the two pots of Feilong, the ones hidden in the pot, isn't it Feilong?

This coward, who spoke nicely before, but escaped faster than anyone else, is really the best in the world.

Lu Shen sank and watched the changes, waiting for Feilong to show up.

Boo!

The two pots were suddenly separated, and a breath of heavenly gangland also flowed out from inside.

The person hiding in the pot also showed up, and it turned out to be Fat Dragon.

"Hey, it's really hard to survive in the demon cave."

Fat Dragon let out a breath and sat down on the ground, looking exhausted.

"I wonder if Brother Lu escaped?"

"Should have escaped!"

"Senior brother Lu said that he has a way to leave, so he must have a way. He doesn't have a lot of brushes, so how can he be favored by the ancestor?"

"The speed of that strong monster is really fast. If I didn't have a pot in my hand to cover my breath and roll into the grass, I would definitely be caught by the strong monster. I'm afraid I would be boiled and eaten by the monster right now. "

"Well, this cave is very hidden. The monster can't find it here. I'll talk about it after I sleep for a while."

Feilong talked to himself, nagging for a long time, then lay down and fell asleep instantly.

He didn't sleep for a long time, when suddenly a wave of evil energy came over, waking Feilong alive from his sleep.

The moment Fei Long opened his sleepy eyes, he saw a somewhat familiar face.

It was the face of a monster, with a pale face, dull eyes, and a faint breath of heaven.

"Grass, the strong monster!"

Feilong was so startled that one Buddha came out of his body, and the other two ascended to the sky. He flipped up violently, and reached out to grab the two pots to save his life, but found that the pots were gone.

"Oh, God treats me too kindly. I, Nangong Zilong, are young and promising. It's really unfair to want me to die young."

Feilong was so frightened that he could pee, he kept complaining to the sky.

"You took care of yourself, left your brother and ran away, what right do you have to be fair?"

In the darkness, came a faint pale voice.

"My senior brother has the ability to protect himself, but I don't. I can only run away."

Feilong shrank into a corner, not daring to look at the other party, but trembling, not busy defending himself.

"Then I will give you a fairness. You have two choices. You can either go to the sky or go to hell. You can choose one. No matter which one you choose, it is very fair."

Said the blue voice.

"Whoever chooses is dead, of course it's fair!"

Fat Long said tremblingly, "Weakly ask, is there a third option?"
