"The Nether Demon Combination Attack? What does this mean? It doesn't seem to be the mysterious technique of our human race." Yu Huanian said.

Unlike Yu Huanian, Yu Zhongjian is the master of the secret realm of Tianji and is well-informed. He has long heard of the art of combined attacks of the Nether Clan, and now he explained to Yu Huanian: "Lord of the Rain Domain, this joint attack of the Nether Clan is one of the unique skills of the Nether Clan's tribe. Its effect on our human race now will even surpass the holy art!"

"Is it so powerful?" Yu Huanian was skeptical.

"According to an intelligence officer's observation, he had seen three powerful men from the early stage of the Ming Clan, besieging a lord of the upper country who had reached the late stage of the Xuan Emperor! The lord of the upper country was originally the best, but after the three Xuan Emperors of the Ming Clan used the combined attack of the Ming Demon, a huge ferocious wolf transformed into two pieces, and actually bit the lord of the upper country who was in the late stage of the Xuan Emperor in one bite!" Yu Zhongjian sighed, "Do you understand? The function of this treasure technique is to use weak to attack the strong, combine the power of many weak people to kill the strong enemy!"

"So powerful?" Yu Huanian knew that the late stage of Emperor Xuan was more than ten times stronger than the early stage of Emperor Xuan! However, under the combined attack of the underworld demons, the three early stage of Emperor Xuan killed a king of the human race in the late stage of Emperor Xuan! Such an increase can only be described as against the will of heaven.

"It's just..." Yu Zhongjian suddenly remembered something and said to Xu Yang: "Sect Master Xu, this art of combining the underworld demons seems to have high requirements for practitioners. It is not so easy to cultivate, right?"

Xu Yang nodded and said, "This kind of secret technique requires the person who casts it to have the same mysterious effect, and secondly, it requires their mind fluctuations to be close to the frequency. The more the mind and spirit are, the stronger the power of the combined attack technique."

"The frequency of mental fluctuations?" The two domain masters looked at each other, "How should we identify this?"

"Don't worry," Xu Yang said confidently, "Since I have handed over the art of the combined attack of the Nether Demon to you, it means that I have made preparations. I can just identify the frequency of the mind fluctuation, and leave this matter to me. Please ask the two domain masters to assemble the elite Xuan practitioners in their respective secret realms, at least the Xuan King level! After they gather, I will group those who are suitable for practicing the combined attack of the Nether Demon to teach them this mysterious technique."

Seeing Xu Yang so sure, the two domain masters were excited and said at the same time: "Thank you, Sect Master Xu." They all knew that this was an opportunity to greatly improve the combat power of the secret realm.

After Xu Yang finished talking about these two things, he did not talk much and said goodbye. He also wanted to return to Tianhu City to lift the seal for his master Luo Baishui.

Not long after, the two domain masters sent people to send the precious medicine and spiritual materials listed on the list to Tianhu City where Xu Yang was.

In the secret room of the backyard, Luo Baishui was still lying in the gray crystal sarcophagus. The breath was almost empty. Qin Guanguan had been living in the secret room, wiping the dust on the sarcophagus every day to accompany Luo Baishui.

The curtain was tilted, and Xu Yang followed Caili, Yu Xuanyu, Buyi and others to the secret room.

"Hello, Master's wife." Xu Yang said with fists to Qin Wanguan.

Qin Guanguan's face was a little thin, and she forced a smile: "Xu Yang, you are back."

"Yes," Xu Yang walked over. He looked at Luo Baishuidao in the gray crystal stone coffin on the bamboo bed. "Master's wife... I'm ready. This time, I must wake up my master."

A hint of hope flashed across Qin Wanguan's sad face. She wanted to say something, but she didn't know where to start, so she could only say: "You must be careful. Don't show off."

"Please rest assured by my master's wife." Xu Yang sat cross-legged on the bamboo bed and said, "Caili, protect me, and do not let anyone disturb me when I open the gray crystal sarcophagus." While speaking, Xu Yang also set up a small protective formation to wrap his sarcophagus and Luo Baishui's.

Caili agreed very quickly, came to Xu Yang, and sat cross-legged.

"It's beginning." Xu Yang's left hand and right hand each turned out, and two completely different mysterious forces rose. In the left hand was a thick golden light, while in the right hand, there was a thick darkness.

"The extreme of earth, the law of Vajra!" As Xu Yang's thoughts were activated, a metal texture gradually appeared in the golden light of his left hand, which made Xu Yang's left palm look like a carved glass.

"The extreme darkness, the law of nirvana." The thought moved again, and in the darkness of Xu Yang's right hand, the pure darkness slightly faded and turned into dark gray. A ball of nirvana power surged out from his palm.

Next, the most critical step is to fusion of two different mysterious laws and forces!

If we talk about fusion of mysterious power, there will be no other person in the world, who is more skilled than Xu Yang. He has already understood the terrible secret method of fusion of the Eight Poles from the Xuanshi stage, and until now, it still has a strong amplification effect on his strength.

It’s just that the fusion of different mysterious powers containing the laws is Xu Yang’s first attempt.

The palms leaned quietly together. The edges of the earth and mysterious power under the blessing of the Vajra Law and the dark and mysterious power under the blessing of the Imperial Law have begun to blend, making a booming sound!

"Fused me!" According to the method of fusing mysterious power on weekdays, Xu Yang slowly compressed his palms and hugged it in his chest to form a ball! In the virtual ball synthesized by his palms, two mysterious powers, one gold and one gray, intersected with each other, like two different armies, starting a small-scale explosion!

A few drops of sweat appeared on Xu Yang's forehead. He found that the fusion of mysterious powers containing different laws was extremely difficult and he almost lost control! Now, he could only try his best to restrain these two mysterious powers, so as not to completely explode.

"I'm so impatient..." Xu Yang smiled bitterly. Although his mental power was strong, it was limited in the end. The gray-gold light ball in his palms fluctuated more and more violently.

Boom!

With a loud bang, the Xuanli Light Ball completely exploded, just like two masters of Xiu Xuan who bombarded each other, causing a powerful aftermath of energy and shooting everywhere!

Xu Yang groaned, it was equivalent to a punch that hit him, heart-wrenching. Fortunately, he was just an experiment this time and did not inject too much mysterious power, otherwise he would definitely be injured.

The small protective formation just laid out was also torn and broken by the energy caused by the collision and explosion of the mysterious power. Fortunately, the small formation was protected by this small formation, otherwise Yu Xuanyu, Buyi and others would have been affected.

"Xu Yang, are you okay?"

Seeing Xu Yang's face pale, Buyi and others surrounded him and asked one after another.

Qin Wanguan sighed: "Xu Yang, you have tried your best... Don't force yourself too much. If you hurt yourself seriously, I believe your master doesn't want to see it."
