The three-headed dog just laughed at Ye Dan for being strong on the outside and weak on the inside. The five internal organs cannot be as powerful as the Barbarian King, and cannot be united inside and outside.

But as soon as it finished speaking, Ye Dan saw a faint light shining from his chest and abdomen, like a human-shaped lantern, with internal organs emitting a light red luster through his ribs and muscles.

The light flashed between the God-killing Bee's eyebrows. She saw the situation in Ye Dan's body clearly and said in surprise: "Heart?"

At this time, Ye Dan's heart became red, like blood-red coral carved, extremely bright. What is even more incredible is that his spiritual sense swept over his heart and could be shocked to find that it was covered with a layer of rich flames!

Burning heart!

Ye Dan also discovered the shortcomings of his physical body at this time. Although his body was extremely strong, he was not afraid of fighting with the Demon King. However, his internal organs were not so strong. Under twenty-eight times the gravity, his muscles and bones could still hold on, but his internal organs could not bear it.

Therefore, he had to forge his internal organs in a short period of time! It was like a big hammer hitting the red iron block and quenching steel, as fast, accurate and ruthless!

In fact, when he had just reached the Yuanqi level, Dan Zun told him a secret method to temper the five internal organs.

Because the power of the Yuanqi is the "internal force" emitted by the five internal organs, along the meridians opened up by the vital energy layer, the "internal force" of the Yuanqi of the five internal organs, and then the meridians and dantian are integrated and enter the leaf layer, and then they begin to absorb the spiritual energy of heaven and earth in the true sense and transform.

However, the cultivation level of the Yuanqi layer was too low, and it was difficult to truly temper the five internal organs, and Ye Dan did not forcefully train. At that time, he was in the Dandao Sect and was mainly busy refining elixirs and opening up the nine palace meridians, and there was no time.

At this time, it is a good time!

When the three-headed dog was mocking, Ye Dan had already taken a deep breath, condensed most of the essence and blood in his body, integrated it into his heart, and recalled the secret method that Danzun once said, igniting the fire of the heart. The essence and blood were like dry firewood and oil, strengthening the flames, and the heart was like a volcano, burning wildly!

This kind of flame is not a true flame and cannot be seen by the eyes, so it can only be sensed by the power of the soul.

But there is no doubt that this power is very terrifying. The soul swept over, like a piece of paper being sent into a fire. A sharp pain will be heard in an instant. After a little longer, it will be scorched and disappeared.

Ye Dan's heart beat violently, and each time it reached its limit. Even the size difference between contraction and beating was twice as big as a fist, changing from a big fist to a big sea bowl, and the entire left chest and ribs were obviously pushed up!

Ye Dan slowed down his progress and relied on the heart fire and huge gravity to continuously temper the heart.

"Puff!" Suddenly, Ye Dan squirted out a mouthful of blood!

"Sir!" Langhao exclaimed. Now it really regards Ye Dan as its master. If something happens to Ye Dan, it will definitely not have a good ending.

"He's fine." Mu Xue said calmly.

Indeed, the blood that Ye Dan sprayed out was not the blood that he imagined, but was shining with black color, and even some dark flesh and flesh impurities, like burned ashes, which were tempered from the heart.

Ye Dan was sweating all over his body, which was very rare. The monks who were stretching the leaf layer rarely sweated and could regulate their bodies.

At this time, Ye Dan's clothes were soaked, obviously in great pain.

However, he could feel that his heart was getting stronger and stronger, like a bright agate, bright red and translucent, like the most perfect ruby, without any flaws!

Bang! Bang! Bang! Bang!

"What sound?" The demon gods were surprised. Even if they were thousands of feet apart, they could hear Ye Dan's heart sound!

It was like a hammer-knocking drum, the huge hammering sound of thousands of horses galloping. The blood pressed out from it filled the blood vessels, making a torrential sensation, making a clamor.

The heart is known as the second brain. Ye Dan doesn't know how long it took. When he came to his senses, he happened to see the demons behind him also coming to the 28th meteorite. He was rushing towards him quickly, but he had no intention of fighting. He didn't want to fight with him, but wanted to surpass him.

"Oh? Do you want to compete?" Ye Dan smiled at the corner of his mouth. The most difficult heart was tempered, which made him double his confidence, relieve the pain, and had more power to protect the other four organs.

He jumped up again and landed towards the twenty-ninth meteorite. This meteorite has approached a radius of two thousand miles, very much like a small planet. Even at Ye Dan's speed, it will take some time to complete it.

However, he did not just rush to speed. After he got rid of the demon clan, he continued to send the energy of essence and blood into his lungs.

The five elements of the heart belong to fire, while the lung belongs to metal. The two are inseparable. Even humans in the mundane world, the strength of the heart and lung function is an important criterion for judging a person's physical fitness.

The bright red blood power just now slowly turned white when it entered the lungs, like flowing milk, but exuded a sharp force. Ye Dan felt that his lungs were stabbed by tens of thousands of needles, and it was soaked in melted iron. A burning heat and tingling pain spread throughout the lungs.

Ding! Ding!

Ye Dan's chest was undulating and gasping violently. His lungs seemed to be constantly beaten by a big hammer, making a clang of steel, extremely terrifying and terrifying.

"Ahem!"

Ye Dan coughed violently, his lungs were burning, just like the feeling of accidentally sucking smoke into his lungs when he was smoking for the first time. But as he coughed, some black powder was coughed out by him, which was also the impurities accumulated by breathing air over the years.

"Ah!" Suddenly, Ye Dan stretched out his hands and stretched his waist hard. Yang Tian roared, scaring the demon gods who had just caught up with him. They were all on guard and looked at him vigilantly.

"Sorry, it's so comfortable, I can't help but roar out." Ye Dan laughed. After his heart and lungs were tempered, he felt that his breathing was completely different from before. Just like after a long-distance running, he stopped to breathe smoothly. Ordinary people who never exercised could not feel the pleasure and pleasure in it.

"Hmph! Pretend to be a ghost!" The three-headed dog was about to surpass Ye Dan, but saw Ye Dan yelling at it: "Dog!"

Ye Dan roared, and a wave of sound rushed towards the three-headed dog, like sound waves, shaking out a circle of ripples in the air, rushing towards it, making its hair float, like being in a tornado, giving it a sensation of pain, but it is difficult to cause harm to it.

However, the God-killing Bee used its powerful soul power to clearly see that a flame pounced on the three-headed dog could directly burn its internal organs, and there were also dense white small swords, with hundreds of them forming a rain of swords and rushing towards the three-headed dog!

"Hide!" As soon as the God-killing Bee spoke, the puzzled three-headed dog had not yet reacted, and saw it fall to the ground suddenly, rolling violently. Its body, nearly a hundred feet tall, hit the hard meteorite, and made a huge roar, like a quasi-king hitting the ground.

"Ah! Ao! Wang!" The three-headed dog screamed and soon stopped moving.

Bang!

Its huge chest exploded, and the gods were in a terrifying state. The powerful three-headed dog had its heart roasted into a ball of coke, and the two lung leaves were filled with countless holes, as if they had been stabbed in a row!

"If you say rudely again, die!" Ye Dan glanced at the remaining demon gods and left in a cold manner.
Chapter completed!
