There was a pop of bones all over his body, and every vibration was like thunder, and the whole room buzzed.

"Amazing!" Lin Chen's god looked inward, and he made a happy discovery.

Fusing with the Ancient Black Dragon Inner Dan, Lin Chen's body underwent a reborn change.

His body was a little taller and stronger, and his whole body was covered with explosive muscles.

The blood in the meridians was as heavy as silver mercury, surging like the Yangtze River, and every tendon was full of toughness, and a slight stretch made a terrifying sound, as if the strengthened version of the "Green Wing Bow" was pulled into a full moon shape.

All the bones had changed color, glowing with a black-gold sheen, harder than the most powerful Hundred Refined Steel.

stomped his foot hard, and with a loud bang, the cave was about to collapse.

"The power of a dragon has finally been reached!" Lin Chen laughed.

One million catties is called the power of a dragon.

Lin Chen's original physical strength was half a dragon's strength, but now it has doubled, which is already very good.

However, it is said that this kind of inner pill can only be refined once, and there is no effect if it is more.

He stretched his body and threw a set of punches, his steps were heavy and powerful, and he felt that each punch was majestic, and his strength was far beyond before.

It seems that the "Lone Star Knife" has been a little unable to keep up, and it feels a little light, and I am afraid that I will have to find a craftsman to smelt the "Shenzhen Iron" into it.

In the next room, Zhou Jing still didn't move, and seemed to be nervously refining Neidan.

Lin Chen didn't want to disturb her, so he sat down, opened the storage spirit ring, and began to check the treasures he had obtained before.

What made him laugh and cry was that the entire storage space had become a world of ice and snow, and everything was frozen.

It took two days for Lin Chen to open the crystal coffin.

What's inside, he's already seen clearly.

The golden sword was extremely heavy, called the "Sword of the Son of Heaven", and it was said to have been used by the emperor to fight in all directions before he was invincible.

It's just that this sword is too heavy, so heavy that he can't even pick it up, it is estimated that it is about two million catties, you can imagine how strong the former emperor was.

"Since I can't use it, let's put it away for now, anyway, I'm used to using knives. Lin Chen pondered.

Picking up that set of martial arts, Lin Chen looked at it carefully.

This set of martial arts is said to surpass the saint-level internal strength, and I don't know what level it is, although it is not created by Huangfu Invincible, but it is very powerful, and it is said to come from a mysterious ancient tomb, called "Northern Immortal Technique".

Lin Chen's previous cultivation of the "Dragon Elephant Technique" was also not clear about the level, but when he got here, he was obviously lagging behind.

Therefore, he had the idea of changing the internal strength mind very early.

"Huangfu Invincible is accustomed to creating his own martial arts, so he didn't fancy this internal skill, and would rather leave it to future generations to cultivate, which happened to be cheaper for me. Lin Chen was in a very happy mood, "But according to him, with this set of 'Northern Immortal Technique', it is enough to cultivate to the realm of surpassing the ninth-order martial saint, or even higher." ”

It took a few days of hard work, and Lin Chen remembered the entire set of martial arts in his heart, only feeling unfathomable.

"It's too fierce! Cultivating this kind of internal strength is extremely dynamic, and it is said that the vitality within a radius of thousands of miles will be emptied, and if the body is not strong enough, the body will be blown up in an instant. Lin Chen was surprised.

Fortunately, he cultivated the "Nine Yang Refining Body Technique", and when he fused the Ancient Black Dragon Inner Dan, he had improved a little and reached the sixth layer.

According to this standard, it is already barely possible to cultivate the "Northern Secret Technique", but the cultivation time cannot exceed three hours a day, otherwise it is easy to have an accident.

He didn't rush to cultivate, but took a break for a while and replenished some dry food and water.

Then, Lin Chen took out the jar and looked at it.

The jar was also translucent, with a small half-barrel inside, which looked like blood, but there was no fishy smell, but a faint fragrance.

"This is a drop of 'Kunpeng Essence Blood'! Oh my God, it's such a terrible thing!" Lin Chen was shocked again.

In the record of Huangfu's invincibility, this drop of "Kunpeng essence blood" was inadvertently obtained when he was invited to travel outside the world.

Kunpeng is an ancient divine beast, whose status far exceeds that of the ancient black dragon, and it is said that its body is extremely large, and its wings can cover 3,000 miles, covering the sun, moon and stars in the sky.

What ninth-order martial saint-level demon emperors are weak chickens in front of Kunpeng.

Even a drop of such blood, although it is against the sky, not everyone can bear it.

Lin Chen estimated that his strength had to be at least improved to the realm of Martial Saint, and the alchemy technique could continue to be improved by one level.

Otherwise, you will still explode and die.

The experience of refining the Ancient Black Dragon Neidan told him that the more powerful something was, the more laborious and dangerous it was to cultivate.

"It's worthy of the Emperor Fu, it's definitely a treasure, so let's take it first. Lin Chen said to himself.

He also figured out what the use of that chilling crystal coffin was.

The first function is to protect the mysterious underground cave sky, so that the dragon corpse will not rot, and also eliminate more than ninety percent of the cultivators, not everyone can withstand this extreme cold.

The second role, of course, is to preserve this precious "Kunpeng Essence Blood".

Otherwise, even if it does not deteriorate over tens of thousands of years, it will turn into a mass of crystals, and its efficacy will be greatly reduced.

After putting away his things, Lin Chen walked around the cave with his hands behind his back, thinking about the future path.

Unintentionally, after getting this treasure, Lin Chen felt that even if he broke away from the "Thai Emperor Academy", he would be fine.

He has no shortage of martial arts cultivation resources, and he has also obtained top-level internal skills, so he only needs enough time to let him be promoted step by step.

The key thing is to let my sisters and sisters also improve their strength, so that they can at least have the power to protect themselves.

With enough strength, you can control your own destiny and not be affected by others.

"I'll also set a small goal, that is, to become the number one powerhouse in the 'Xuanhuang World'. Lin Chen was full of confidence.

As long as it reaches that height, what Martial Emperor Cultivation, what Ninth Order Martial Saint, and what "Jixia Academy" are all out of the question.

After determining the goal, Lin Chen was suddenly full of motivation.

But before continuing the retreat, he also had to go to see Zhou Jing's condition.

After all, Zhou Jing has been staying next door for so long, and there has been no movement, and he doesn't know what the progress is.

Walking over gently, Lin Chen saw the situation in the room at a glance.

"What, she's already refined the Ancient Inner Dan!" Lin Chen was taken aback.

Because at this moment, Zhou Jing was already empty-handed, she closed her eyes tightly, trying her best to maintain a cross-legged posture.

But the clothes on her body were torn by the terrifying power, and now they are almost red fruits.

Not only that, Zhou Jing's exposed skin was tinged with an abnormal flush, and traces of scales appeared, as if he could go crazy at any time and turn into a monster covered in black scales.

"Sister Jing, what's wrong with you?!" Lin Chen walked over quickly and grabbed her hands.

Zhou Jing couldn't open his eyes, but he struggled to convey a wisp of divine thought.

"I'm so hot, it looks like there's a volcano about to erupt in my body!

This situation was not the same as what Lin Chen had encountered before.

But considering that Zhou Jing hadn't cultivated hard before, it was likely that he wouldn't be able to hold on.

So Lin Chen immediately held her in his arms and carefully released the cold air on his body.

The two hugged each other tightly and maintained this state, and Zhou Jing seemed to feel much better.

After a few more days, the flush on her body dissipated, her skin returned to a snow-white appearance, and even a faint black dragon breath filled her breath when she breathed.

"Brother Chen, I feel more than ten times stronger than before!" Zhou Jing opened his eyes with an extremely happy expression.

"That's a must," Lin Chen smiled, "I don't dare to say that you now have the power of a dragon, the strength of hundreds of thousands of catties, and you should also have it." ”

Zhou Jing nodded, and immediately found his embarrassment.

In fact, she had been in a desperate struggle almost all the time, her nerves were tense, and she was always battling the soul of the ancient black dragon, so she neglected her clothes.

On her delicate face, two delicate crimsons suddenly appeared, and at the same time, she buried her head deep in Lin Chen's chest.

"Promise me to be kind to me in the future and let me always follow you. Zhou Jing said in a voice as thin as a mosquito.

"Well, don't worry. Lin Chen hugged her tightly, and the two young bodies immediately merged into one.

It's as if the thunder of heaven has stirred up the fire.

The entire cave was shaking violently.
