In this way, he refined this black heavenly tribulation ten times in total. After ten times, all the destructive aura in the black heavenly tribulation disappeared, and even most of the energy in it was refined by Han Yang.

"Haha, there should be no problem at this time!" Han Yang grinned, then his soul power surged out, leading the gentle black heavenly tribulation and headed straight towards his right arm. Emperor Burning Tian Long said, let him start from the simplicity. He thought about it and decided to start from the right arm of the upper limb bone.

If it is ruined, at worst, you will become Yang Guo and it will not be too miserable.

There was a bone vein piercing through the bone in his right arm. He immediately guided the black heavenly tribulation and drilled straight into the entrance of the bone vein.

This black heavenly tribulation was easily entered, but as soon as this thing was in, even with Han Yang's ability to endure pain at this moment, he grinned in pain, his face turned red in an instant, and his forehead was sweating.

He could not describe this kind of pain in words. He could only activate the mental method of the True Dragon Bone Forging Art, strive to control this black heavenly tribulation, and slowly move forward in this subtle bone vein.

This bone vein is really strange. Although it is extremely subtle and looks fragile, under the urging of the True Dragon Bone Forging Technique, a terrible devouring force was born in the bone vein. In less than a minute, all the energy in this black heavenly tribulation was swallowed up.

After devouring these energy, Han Yang obviously realized that the small bone vein seemed to have become thicker. Obviously, these energy was swallowed into the bone vein, and even more obvious. He felt that the bone where the small bone vein was suddenly undergoing some qualitative change. Not only did the density increase a lot, but it also seemed that the toughness and weight increased significantly, and even the color changed. It turned out to be white, but now it had a hint of gold.

Seeing this scene, Han Yang couldn't help but be overjoyed. He knew that the symbol of the successful practice of the True Dragon Bone Forging Art was that every bone, from the inside out, turned golden. In other words, by that time, the bones in his body would probably reach an extremely powerful level, which was a bit unimaginable.

Han Yang laughed and looked excited. He knew that the martial arts taught by Emperor Burning Heaven were indeed not ordinary.

Immediately, without saying a word, he followed the previous process and pulled off a black heavenly tribulation from the black heavenly tribulation and began to practice again.

He first used the Yuan-Swallowing Body Technique to refine all the destructive aura in the Black Heavenly Tribulation. Of course, in this process, his cultivation began to slowly improve. Then, he used the refined Black Heavenly Tribulation to practice the True Dragon Body Fighting Technique.

In this way, time passed by rapidly, and in a blink of an eye, three days passed.

At some point, Han Yang suddenly opened his eyes, and a light flashed in his eyes. He stood up and smiled. Suddenly, the cultivation level in his body exploded, and it turned out to be the aura of the sixth level of the Golden Pill.

Then, he punched out with his right hand, and suddenly, a violent palm force instantly slapped out, shaking the entire space vibrated.

A few shocking colors flashed in his eyes. After devouring and refining the black heavenly tribulation in the sky these days, his cultivation level has been increased from the fifth level of the golden elixir to the sixth level of the golden elixir. But what surprised him was that so much energy in the black heavenly tribulation only allowed him to practice the True Dragon Bone Forging Technique to complete the tempering of the big arm bone.

But even so, after just slapping this palm, he instantly understood the power of the True Dragon Bone Forging Technique, because at the moment when energy flowed through his arm, he was surprised to find that the big arm bone that he had tempered by himself seemed like an energy amplifier, instantly increasing the power of the sixth level of his golden elixir. His palm, which was a small-scale golden elixir, was as powerful as the sixth level of the golden elixir, and even even more so.

"Haha, the True Dragon Bone Forging Technique is indeed perverted! If all of this is tempered, I don't know how terrifying the increase will be! If combined with the Blood Burning Technique, my combat power will probably reach a more terrifying level!"

He said with a look of joy.

Unexpectedly, as soon as he finished speaking, a voice suddenly came.

"That's the True Dragon Bone Forging Technique, which is the core exercise of my dragon clan. How can it be less powerful?"

The figure of the Dragon Emperor of Burning Heaven appeared faintly in front of Han Yang. He looked at Han Yang, and a satisfied smile flashed in his eyes, and said, "It's not bad, you kid, it seems that you have really figured out a way!"

Han Yang laughed and said, "Of course, I am talented and born smart!"

"I'll give you some sunshine and you'll be brilliant!" Emperor Burning Tian Long looked at his proud look, glared at him, and cursed.

Han Yang immediately smiled embarrassedly and said, "Of course, thanks to Senior Fen Tian!"

Fen Tian smiled speechlessly, then he thought for a while, and suddenly looked at Han Yang and said seriously: "In this world, strange energy like this black heavenly tribulation is very difficult to find. If you want to continue practicing the True Dragon Bone Forging Art, you must collect this strange energy, otherwise you will not be able to make progress!"

Han Yang nodded and smiled, "I know, don't worry, you old man. Looking back, I'll try to have a few more thunder tribulations!"

Fen Tian was speechless and thought for a while. He said, "You kid, be honest and don't make too much noise. If you make a more terrifying heavenly tribulation, you will be killed by yourself before the dragon ball is swallowed. Do you think the heavenly tribulation is so fun. Heavenly tribulation, but there is no one who is not afraid of it. How can you be like you?"

Han Yang had no choice but to nod, "Yes, Senior Fen Tian's words, I remember!"

"Okay, just get out of here if you have nothing to do, I'm going to continue sleeping!" Emperor Burning Tian cursed with a smile, and then disappeared.

Han Yang grinned, and with a thought, he came out of the Ancestral Dragon Holy Pearl.

Returning to his body, Han Yang felt his power, and a strong look of joy surged in his expression. Finally, the sixth level of the Golden Pill is at the sixth level. This time, I really want to thank the black heavenly tribulation. If it weren't for this thing, how could he break through so quickly?

But after thinking about it, he frowned. Then, with a thought, the black incense burner flew out of his body and landed on the ground.

He stayed in the room for another three hours before going out.
