"Roar~"

The ground crocodile dragon endured its injuries and quickly crawled into the rat holes in the walls around the cave, and the speed was unbelievably fast, and it burrowed into the cave at once.

However, after all, after fighting with the Giant Rat King for a while, the Giant Rat King's sneak attack left a lot of wounds on the Earth Crocodile Dragon.

The Earth Crocodile also consumed a lot of physical strength.

Yuan Lin flew at great speed, and while swallowing the earth's heart milk, it can be said that the demonic physical strength has always maintained the peak state.

The speed is called fast.

After a while, he shook off the ground crocodile.

The roar of the Earth Crocodile grew farther and smaller, until it was finally inaudible.

"Whew, finally got rid of the ground crocodile. Yuan Lin wiped the cold sweat from his forehead, and secretly warned himself in his heart not to offend any female creatures.

Seeing the jade bottle in his hand, his heart was on fire.

Yuan Lin's eyes scanned the surroundings, and then he quickly searched for a direction, flew for a while, and found a quiet cave.

In this cave, there lived a big insect in the mortal demon stage, which was easily solved by Yuan Lin. Occupy the cave.

Yuan Lin spread his hands, took out nine drops of Ten Thousand Years Earth Heart Milk, and looked at the crystal that exuded a charming light in his hand, his eyes were hot.

"If you swallow it, you should be able to break through the late stage of foundation building. Yuan Lin muttered.

"Boy Yuan Lin, the spiritual power contained in this 10,000-year-old earth-core milk, as long as you reach the peak of foundation building in an instant, the transformation demon tribulation will appear later. At this time, the old man hurriedly reminded.

What the?

Yuan Lin looked stunned, and looked at the Ten Thousand Year Earth Heart Milk in his hand in shock. A drop of 10,000-year-old earth-centered milk instantly broke through the foundation building period and began to form a demon tribulation and condense the demon pill.

Yuan Lin shook his head, the transformation of the knot pill had always been what Yuan Lin expected. However, now is not the time, and the transformation tribulation of demon beasts is not so simple to get through.

The transformation of the demon beast into a sincere and benevolent form was originally a move against the sky. The Heavenly Dao sent down the Heavenly Tribulation, on the one hand, as a punishment for the demon beast against the sky. On the other hand, there are the trials.

Survive the transformation of the demon and transform into the form of sincerity and benevolence. Death.

The Transfiguration Tribulation is a tribulation that every demon beast must go through, and every demon beast must be careful and well prepared.

Yuan Lin was no exception, he had to survive the Transformation Demon Tribulation with great certainty.

Thinking of this, Yuan Lin turned his hand and put away the Ten Thousand Years Earth Heart Milk. Take out the jade bottle.

The milk of the heart of the earth cannot be swallowed for ten thousand years, but the milk of the earth can be swallowed.

The spiritual power contained in this jade bottle is too huge. Along the way, every time Yuan Lin devoured a few drops of the earth's core milk, the demonic power in his body was instantly replenished.

It's a blood pill.

With it, Yuan Lin's demonic power can be kept at its peak at any time.

With burning eyes, Yuan Lin opened the cork, sucked in his mouth, and sucked more than a dozen drops of the earth's core milk stream into his abdomen. The abdominal cavity immediately seemed to explode with tens of thousands of tons of explosives, and the huge aura generated by the opening of the earth's center hit the internal organs. The internal organs seemed to be beaten fiercely, and the pain came directly to his mind, and cold sweat dripped down Yuan Lin's forehead, and his face was a little distorted. However, the pain did not stop because of his feelings, but became more ferocious.

Streams of aura wandered wantonly in the body, colliding. The meridians of the brace are a little swollen and sore.

Yuan Lin has experienced the tempering of the earth's evil yin veins, and the meridians and internal organs in his body are incomparably hard.

However, under the impact of the huge aura of the earth's heart milk, there were bursts of pain. It can be imagined how huge the earth-centered milk aura is.

This huge aura was everywhere, and they swam between Yuan Lin's skin, and small bumps bulged up on Yuan Lin's body, undulating one after another. It's like a small snake hiding under its skin, scurrying around.

On the cheeks, the left half of the cheek bulges for a while, and the forehead bulges again. It looks scary. However, Yuan Lin couldn't feel any of this.

He noticed a detail now, these auras were actually purposefully washing over the bones in his body.

With each wash, a large amount of aura burrowed into the bones, and the bones were rendered milky white. Suddenly, at this time, Yuan Lin's body shook. There seemed to be hundreds of millions of ants crawling on the bones, constantly gnawing at Yuan Lin's bones, and a biting sensation that penetrated deep into the bone marrow spread out rapidly, spreading to every corner of the body.

It was too painful, Yuan Lin gritted his teeth, his body trembled, and his appearance was hideous and terrifying.

"What the hell is going on?" Yuan Lin roared in his heart.

Why, there was no such situation when I started to swallow the earth's milk, but now it has appeared.

"Yuan Lin, hold back. This is the magic of the Earth's Milk. The reason why the geocentric milk is precious is not because it contains a huge aura, the most amazing thing about the geocentric milk is that it can be quenched and refined**. The old man shouted.

"Why, I couldn't feel the pain of the earth's core milk before?" asked Yuan Lin with a roar.

"It was my temporary suppression of the Earth's Heart Emulsion, and now that there are no enemies, its effects are unleashed. Qing Lao said.

"Old Qing, why didn't you tell me earlier. ”

"Hehe, I'm training your tough surname. Boy Yuan Lin, your will and tenacity are already very strong. That's not all, though. In the future, when you want to swallow the 10,000-year-old earth-centered milk, the pain of refining the bones is hundreds of times more painful than the earth's heart-centered milk, which is to give you a preventive injection in advance. The old man chuckled, a deliberate look flashing in his eyes. It turned out that this was the case, and Yuan Lin understood.

"This little pain is nothing to you. You're going to get through it. ”

"How could this little pain hit me. Yuan Lin's eyes were certain, and there was a strong confidence on his face.

A strong and perverted will, let the 'cruel' tempering of the earth's milk**.

Minutes and seconds passed. The miraculous effect of the earth's milk is also revealed at this moment. Yuan Lin could feel that ** had strengthened again, and his bones were harder.

Overjoyed, Yuan Lin ran the law to decide, and the clumps of spiritual energy were transformed into demonic liquid and flowed into the dantian.

A stream of earth-centered milk is swallowed, sucked again, refined, swallowed, refined, swallowed.

After repeated repeats, the earth's core milk swallowed a small half bottle, and Yuan Lin finally reached the peak of foundation building, and he was one step away from being able to form a pill.

Yuan Lin even felt that his transformation demon tribulation was about to descend soon.

"After the Xuantian Cave Realm is over this time, returning to the Niuman Mountain Range should be a tribulation. Yuan Lin's eyes were solemn.

You must find some treasures or spirit essences in the Xuantian Cave Realm to increase the chances of winning the tribulation.

"Elder Qing, which direction am I going to look in now?" asked Yuan Lin.

In the dantian, the desolate monument flashed with blue light, and one after another the blue light spread outward, and after a few breaths, the old man's closed eyes opened in an instant, and said, "Yuan Lin boy, fly south, I feel that there are a large number of soul fluctuations there, not a human or a demon beast, it should be a spiritual essence." Just go. ”

Yuan Lin's eyes lit up, his mind moved, and the demon cloud suddenly doubled, and the speed was like lightning, shooting out towards the south.

Suspended above a valley that is ordinary, there is nothing to be interested in.

"Boy Yuan Lin, this valley is a little weird, and the entire valley has been laid out with a formation. Moreover, there was an astonishing resentment and death in the valley, which was blocked by the formation. Qing Lao frowned and said.

Yuan Lin's face changed, he calmed down his excited emotions, and the demon boy carefully swept across the valley.

"Sure enough, it's a formation, who laid the formation here. Yuan Lin said solemnly. Someone has set up a formation here, indicating that someone has been to the valley before, and it may be that the spirit essence in the valley is the person who set up the formation.

"Elder Qing, is there still a spirit essence in the valley?" asked Yuan Lin.

"Yes, there is. Judging from the extent of damage to the foundation of this formation, it has existed for a hundred years. And there is no trace of anyone breaking the formation until now. "Qing Lao Dao.
