"By the way, I don't need it myself, but it seems that I can leave it to the four ghost kings for use?" Xu Yang's eyes lit up.

The four ghost kings themselves rely on devouring the remaining souls and strengthening themselves. Moreover, the more fierce the remaining souls are, the more they are, the more they are. It is very suitable to give this soul crystal core to them.

Thinking of this, Xu Yang urged Zhenxuan Tower to transport it, took out a scroll of paintings, and spread it out with a whirlwind. Four rays of different colors shot out, landed on the ground, turning into the appearance of the four ghost kings.

"Master hasn't summoned me for a long time, so I'm so frustrated." The Ghost King of Tijuan said to Xu Yang pitifully.

The other three ghost kings nodded one after another. It seemed that during this period, they had been in the painting scroll, making the four ghosts so depressed.

Xu Yang said: "Since we came to Zhongzhou, we have never had the opportunity to release you, but this time it is beneficial, so we summoned you to appear."

Xu Yang was talking about the truth. When he participated in the Xiaotianlu Trial, he was monitored by the ten Buddhas in every move. How dare he release four king-level ghosts? You should know that the Xuan Cultivator and the Yin Gui are born enemies. When he was in Yingzhou, the evil emperor Luo Baishui knew Xu Yang's roots and bottom lines, and knew that the four ghosts surrendered to Xu Yang, so he naturally would not interfere more. Others were frightened by the name of the evil emperor and would not offend Xu Yang. However, it was different in Zhongzhou. These Buddhas were not in the mood to listen to Xu Yang's explanations. Seeing the king-level great ghost, they would definitely turn it into ashes with one palm.

Later, when he went to southern Xinjiang, Zou Xingyun and Xu Yang walked with him. Considering that it would take some verbal slap to summon the ghosts, Xu Yang did not do this. Later, it was the Battle of the Five Great Sages, and then until now, when exploring the underground mysteries, he was separated from his fellow disciples, and Xu Yang was alone, so that the four ghosts could see the light of heaven again.

"This is Zhongzhou. The richness of the mysterious energy is indeed much better than that of small places like Yingzhou." The ebony ghost king looked around and exclaimed.

"What are the benefits of the master talking about compared to this?" The Ghost King Chili was most concerned about this.

"Look." Xu Yang took out a jade box from the storage ring and opened it immediately.

A soft white light shone out, illuminating the entire broken tomb chamber. Four blazing white soul crystal cores lay quietly in the jade box.

"What, what a powerful residual soul power!" The four ghost kings gathered around like an old gourmet who saw the delicious food.

"This is the soul crystal core left by the powerful aliens in the wilderness era after the death of the powerful aliens. After you swallow it, your strength should improve." Xu Yang explained.

"Thank you, Master!" The four ghost kings cheered in unison, each snatched a blazing white soul crystal core and swallowed it directly into their mouths.

A ** mind power surged out of the soul crystal core and launched an impact on the four ghost kings. However, the four ghosts were all ghost kings. The masters who played with the mind power easily defended against the mind impact.

The energy of resentment with different colors burst out from the bodies of the four ghost kings, completely enveloping the blazing white soul crystal core, melting the residual souls in it, and devouring these mental powers.

Not long after, the four ghost kings successfully devoured them one after another. Their eyes were filled with divine light, and they obviously gained great benefits.

The King of Ghosts Chili licked his lips and said, "Master. Is there any? It's so delicious."

"Yes, just by absorbing this soul crystal core, I feel like there are signs of breaking through to the middle stage of the Ghost King. It's really a divine thing." The Ebony Ghost King also said in agreement.

"There is another one here, but it is just a soul crystal core left by a Xuanhuang-level master." Xu Yang said.

"Xuanhuang level?!" The four ghost kings' eyes lit up, but then they dimmed.

"Master. The soul crystal core left by Master Xuanhuang is of course good, but we may not have the ability to resist the soul impact it emits." The ghost king of Tijuan said in embarrassment. She looked at the green soul crystal core in the cloud stone coffin and said reluctantly.

"It's okay. You all have soul marks in me, so you can achieve the commonality of mental power. With my mental power, plus you four, it should be enough to resist the mental impact of the Xuanhuang strong man." Xu Yang said.

"I'm afraid it won't work..." The ebony ghost king shook his head and said, "The master's mental power should be at the level of the Xuan King. Together with the four of us, that is, five Xuan Kings, it's too risky to devour the soul crystal core of a Xuan Emperor master."

"I agree with the master's opinion. It's better to take a try. Wealth is dangerous," the eyes of the Ghost King Chili flashed red. "If the swallowing is successful, we will immediately improve to a small level and make great progress in our strength."

The four major ghost kings spoke and expressed their opinions. Only the Ghost King of Chili wanted to take a risk, while the other three ghost kings all advocated being stern.

Xu Yang smiled and said, "It's okay, leave everything to me."

When the four ghost kings were still in Yingzhou, how could they know that when Xu Yang was in Zhongzhou, when he was studying the solidified Xuan Formation, his mental power had a breakthrough. Now he has been promoted to the level of Xuanhuang?

"Come on, each of you will emit the power of your mind and enter my sea of ​​consciousness!" Xu Yang sat down in front of the coffin.

The four great ghost kings absolutely obeyed Xu Yang's orders. They sat cross-legged around Xu Yang, and each shot out his mind and spiritual power from his eyebrows. Under Xu Yang's guidance, they entered Xu Yang's sea of ​​consciousness.

"I haven't seen you for a long time, and the master's sea of ​​consciousness has become much wider?" The Ghost King Cangming was a little surprised.

A blue light flashed, and Xu Yang's mind incarnation appeared before the mind incarnation of the four ghost kings. He transformed into a blue shirt and flowed out of the dust: "Everyone, all are ready. I am about to pick up the soul crystal core of the Xuanhuang-level master and enter the sea of ​​consciousness!"

The four major ghost kings all responded, and their faces were solemn.

The mist rolled over the sea of ​​consciousness, and suddenly the mist dissipated layer by layer. A blue sun appeared in Xu Yang's sea of ​​consciousness space. It was a bit illusory at first, but later it gradually condensed.

"Swish swish swish swish..."

At the moment when the blue sun was completely solidified, blue lights shot towards Xu Yang and the four ghost kings in the sea of ​​consciousness like sharp swords.

"Connect your mind and me to resist the impact of your mind!" Lanshan Xu Yang shouted softly, and the four ghost kings' mind incarnations each stretched out a palm and pressed it against the back of Lanshan Xu Yang.

A dazzling blue light shot out and turned into an arc, blocking the rushing blue sword.
