"The source of darkness is the innate substance with the strongest dark attribute, and this kind of existence, once formed, has spirituality, so they can only assist one person, and it is impossible for many people to absorb it!"

"Hmm!"

Hearing this, Long Xingyu also nodded lightly.

It's also a good thing for him.

Because, in this way, he will have access to the source of darkness in its entirety, and not a part of it, which is more beneficial to him!

"Without the source of darkness, I'm afraid these shattering black flames will disappear in the future!" Long Xingyu guessed as he looked at the black flames burning outside the enchantment.

Not to mention the future, without the energy support of the source of darkness at this moment, the shattering black flame outside the barrier, the fire has already shown signs of weakening!

"You're right. This so-called shattering black flame is actually the birth of the power of the source of darkness combined with the environment here, and the lack of the source of darkness is equivalent to the lack of the power of regeneration, and this shattering black flame will disappear one day with the passage of time. The black dragon nodded.

"But no one would have thought that it would have something to do with me!"

Long Xingyu said with a smile.

Now that the most important thing has been done, his mind has come alive.

He looked to the other side of the trunk, the human skeleton that was leaning against it.

This person has been dead for I don't know how many years, and the things on his body are almost weathered. It may have been here before the establishment of the Great Metaphysical Palace.

Perhaps it was because he wanted to obtain the source of darkness, which eventually led to the sinking of his mind and annihilation in the darkness, so that his body died and lost his life.

"Hmm!"

Long Xingyu's eyes suddenly moved.

He bent down, sat down on the bones, and took out a black jade plaque!

He blew away the dust that covered the surface of the jade plaque, which was crystal clear and had a texture like jade and crystal. There are some strange patterns carved with the Great Dark Technique written on one side and the Qiankun Holy Sect written on the other!

"Qiankun Holy Sect, Great Dark Technique?"

Long Xingyu's eyes fell on the jade plate and read.

According to his guess, the Qiankun Holy Sect should be the name of a sect.

And the Great Dark Technique should be martial arts!

"This is the soul jade, a rare artifact used by the great sects to record advanced martial arts, even if it goes through tens of thousands or even hundreds of thousands of years, this thing will not be damaged. Black Dragon Transmission explained.

"Then how should this soul jade be used?" Long Xingyu asked thoughtfully.

As soon as the voice fell, the black dragon immediately replied: "It's simple, just touch it with your spirit!"

"Well, I'll try!"

Long Xingyu nodded lightly, pasted it on the surface of his forehead, and touched it with spiritual power.

Suddenly, a sense of trance struck.

After the trance, the vision gradually became clearer.

It was a white world, and suddenly, a black shadow appeared, performing its fists.

With a punch, the surrounding light faded at a speed visible to the naked eye, and the white world became pitch black in the blink of an eye, as if all the light was swallowed by the dark power inspired by Fang Cai's punch.

......

Long Xingyu opened his eyes.

"How?"

Black Dragon Transmission asked.

"The Great Dark Technique recorded in this soul jade should be the sum of a set of martial arts. And I just learned a boxing method from it, I call it Black Hole Fist!" Long Xingyu said.

The black shadow seemed to want to do something after performing the punch technique.

However, Long Xingyu's spiritual strength is not strong now, and after reading the boxing technique, he has reached the limit, so the soul jade automatically stops inheriting, and the mysterious black shadow also stops.

Obviously, if you want to see the martial arts behind clearly, you must enhance your spiritual strength.

Only in this way can we inherit the complete inheritance in the soul jade!

"It's time to leave!"

Long Xingyu said.

On this trip, he gained a lot, not only obtained the source of darkness, which can be called the strongest innate attribute substance. The cultivation also reached the double level of the Qi Mansion Realm, and he also harvested the Great Dark Technique recorded in this soul jade.

Each of them is an enviable and rare opportunity.

After deciding to leave, Long Xingyu entered the Dragon Demon Punishment Divine Platform, and the latter was the carrying object, passing through the sea of fire and returning to the Black Flame Pool.

"How long has it been?" asked Long Xingyu about the black dragon.

Because of refining the source of darkness, he had a vague concept of time, and he didn't know exactly how much time had passed.

"Two days!"

The black dragon replied.

Hearing this, Long Xingyu nodded and said: "Then there is no overtime, the time for the leader of the year-end Dabi to enter the Black Flame Pool is the longest among all of them, there are three days, and if it does not exceed this time, it is not considered a violation!"

"Do you have a method of concealing your cultivation?" Long Xingyu asked Black Dragon.

When refining the Qi Realm, it is difficult for outsiders to see the cultivation level of others.

However, after reaching the Qi Fu realm, when the spiritual power is transformed into a true element, people in the same or above realms can easily sense it.

At this time, it is only about half a month before the end of the year-end competition. If outsiders knew that he had reached the second level of the Qi Mansion Realm, this speed would be a bit appalling!

Therefore, it is better to hide it for one more day!

"Yes, I have a hidden element technique that can hide the fluctuations of the true element, so that outsiders can't judge your cultivation!" the black dragon said.

Next, the black dragon taught the Hidden Yuan Technique to Long Xingyu.

There is still a full day left before the time limit of the leader.

Therefore, Long Xingyu also planned to successfully cultivate the Hidden Yuan Technique and then leave.

With his talent for comprehension, this Hidden Yuan Technique was naturally not difficult for him.

From start to finish, he didn't even use a day. It only took half a day for him to successfully cultivate the Hidden Yuan Technique.

This technique was cast, and in the dark, Long Xingyu's aura immediately changed slightly!

The fluctuations that belonged to the true element disappeared completely......

After leaving the Black Flame Pool, Long Xingyu immediately returned to the palace. As soon as he arrived at the palace, he immediately closed the door and seized the time to cultivate again.

After stepping into the Qi Mansion Realm, he no longer needed to use the Qi Refining Method.

In the future, his cultivation will rely on exercises, and the true yuan seed that will become a black dragon after fusing the source of darkness is the core of his future cultivation.

Fortunately, the level of the Dragon Transformation Technique is not low, and the speed of absorbing the aura of heaven and earth and transforming it into true yuan is quite good.

In the future, after the Dragon Transformation Technique is completed, after transferring to the Ancestral Dragon Sutra, his cultivation speed will be improved!

.......

Knock knock!

When Long Xingyu was in a state of cultivation, there was a sudden knock on the door.

Hearing this, Long Xingyu immediately broke away from his cultivation state, opened his eyes, frowned slightly, and asked, "What's the matter?"

The voice of the attendant came from outside: "Childe, there is a guest coming!"

"Guest!"

Long Xingyu muttered silently, got up and opened the door, and suddenly saw a beautiful shadow standing outside the door.

This person has a peerless appearance, a slender body, and a temperament like ice and snow.

It was not long ago that Mu Xuehan, who signed the marriage letter with him.

"Why are you here?"

Long Xingyu's expression rarely showed a touch of surprise.

Whoever comes to him, he will not be surprised, except for Mu Xuehan.

Because, she was born with an indifferent temperament that no one approaches, and it is hard to imagine that she would take the initiative to come to herself......
