Although the ancient saint corpse today is powerful, it has not been sacrificed and refined, but is only forcibly fighting with the brute force and speed of the holy body. Therefore, the ancient saint corpse that has not been sacrificed and refined can only kill the four-tribulation World Honored One at most.

The Five Tribulation World Honored One has a deep understanding of the laws of space and can already do space shuttle at any time, or even use it in battle to move in a short distance! In this way, it is very difficult for the Holy Corpse to attack the Five Tribulation World Honored One. If you can't beat the enemy, what is the effect of the strongest power?

If the Nether Clan sacrifices and refining the ancient saint corpse, the power of the saint's corpse should be greatly improved, and even use certain mysterious methods to attack and kill enemies. At that time, against the powerful Buddha who are five tribulations or even more than five tribulations, there will be no chance of winning.

Before Xu Yang could learn how to refine corpses, he put away the animal skin scroll and then stood up straight.

"I have limited time to use the superposition secret technique, so I must take advantage of this time to complete my plan!" Xu Yang found another page of the Golden Book from the storage ring of the King Stone World Honored One.

The golden book has two big words "Joint Attack", and the small words below explain: "The golden book on this page has three columns, which can allow three passers-by to join a team together and be regarded as one person. The three-person team can enter a palace through a light gate at the same time, and the difficulty of the test will not increase."

The small words on the back indicate the scope of use, which is within the entire underground palace.

"The transfer gold book I got at that time could only be used in the Black Palace No. 21, and it would be invalid if I walked out of the Black Palace. And this page of gold book has a significantly larger scope and a great effect. It should have cost a considerable price to find this page of gold book."

Xu Yang put away the golden book. This should be the team Jin Shu that the King of Stone planned to use with King Jin Tai. After King Jin Tai recovered from his injury, the two of them stepped into the No. 54 Black Palace together to test the four-star secret key.

Xu Yang wiped his hand on his face, and the membrane vibrated, and it turned into the appearance of the King Stone World Honored One. His breath changed all over his body. Under the control of the soul-casting technique, it was soon similar to the dead King Stone World Honored One. It was not a real familiar person, so it was difficult to see the flaws.

As for the height and body size differences between Xu Yang and the King Stone World Master, Xu Yang controlled his bones under the ability to change the bones, and the simulation scores were also not bad.

"Okay, he shouldn't doubt it when he meets King Jin Tai in this way."

Xu Yang removed the golden array talisman that blocked the light gate, walked straight to the light gate on the north side, and stepped into the No. 43 Black Palace. In this Black Palace, the guarding spirit beast was a blood-patterned black panther, and its strength was enough to match the peak of the Three Tribulations World Honored One.

Xu Yang had not experienced the No. 43 Black Palace Test before. After stepping in, according to the principle, the blood-patterned Black Panther statue would wake up and attack Xu Yang. However, Xu Yang now uses the technique of soul-casting to transform into the appearance of the Nether Stone World Honored One! The Nether Honored One had passed the No. 43 Black Palace Test.

So, Xu Yang walked directly next to the blood-patterned black panther statue without any danger.

"It's a pity that I don't have time. If I have time, transform into different soul auras and scan all the black palaces in the entire underground palace, how many secret keys will I get?" Xu Yang laughed in his heart. This is exactly what the Beast Clan and the Nether Clan are doing at this moment. While they are preparing to break through the innermost black palace, they arrange for the strong to clean up the outer black palace and strive to obtain more secret keys.

For example, if Xu Yang stepped into the Black Palace No. 43 with his original appearance and soul breath, it would definitely trigger the awakening of the blood-patterned black panther. He killed this spirit beast and could harvest a three-star secret key. Then, Xu Yang transformed into another person's soul breath and face. The blood-patterned black panther in the Black Palace No. 43 will definitely wake up again because it cannot recognize the difference between Xu Yang who has performed the soul-casting technique and the previous Xu Yang. In this way, Xu Yang can get another three-star secret key. If this continues, Xu Yang can almost get as many secret keys as he wants.

However, according to the information obtained from the powerful men of the Nether Clan, the eight four-star black palaces on the innermost level are guarded by real spirit beasts. In other words, these spirit beasts will not be resurrected after death, and can only provide a four-star secret key, which cannot be obtained without restrictions.

"It depends on the situation... the real spirit beast in the four-star black palace may not be easy to deal with. At least the four-tribulation World Honored One cannot fight against. You can see the plan of the Netherworld Stone World Honored One. If he can deal with it, why wait for King Jin Tai to recover from his injuries?"

With this idea, Xu Yang stepped into Black Palace No. 53.

"Elder of the Nether Stone, everything has been resolved?" King Jin Tai's face was still pale and his breath was listless. He smiled at Xu Yang's illusion of the Nether Stone Master.

Xu Yang nodded slightly and said in the tone of the World-Honored Lord of the Underworld: "Well, it's just a little trouble. I also got two secret keys this time, which is a small reward."

"Hey, why didn't Elder Nether Crane come back with you?" King Jin Tai coughed and said.

Xu Yang snorted, "Elder Nether Skull? After the matter is resolved, I will send him to other outer black palaces and continue to collect secret keys. As for the precious medicine to cure your injuries, I have brought it from the White House No. 33."

While speaking, Xu Yang threw the exchanged small jade bottle to King Jin Tai. Xu Yang had already identified the precious medicine in this bottle. It was a Jiuhua Pill, which had a good effect on expelling the extraordinary power.

King Jin Tai quickly took the medicine bottle and said gratefully: "Thank you, Elder Mingshi, for giving the medicine. I must have gone through fire and water for the Nether clan, and I will die after death..."

"Forget it!" Xu Yang waved his hand impatiently, "You'd better heal your wounds quickly, I hope you can be worthy of the efforts of our clan to you."

"Sure, certain." King Jin Tai nodded repeatedly, then took Jiuhua Pill, closed his eyes and sat cross-legged, and adjusted his breathing. Above his head, there was a lot of blood-colored mist rising.

At this time, it would be easy for Xu Yang to kill King Jin Tai. However, Xu Yang has his own plan and he will not abandon his general plan for the sake of a temporary opportunity.

However, something unexpected happened to Xu Yang. When King Jin Tai was healing, a light flashed. In the light gate on the west side, a Master of the Underworld came in!

This world-famous master of the Underworld clan has three tribulations of cultivation. He first saluted Xu Yang's illusion of the Underworld Stone Master, and then said: "Elder of the Underworld Stone, I have obtained a two-star secret key in the No. 52 Black Palace. Will I hand it over to you now?"

Xu Yang didn't know the name of the Buddha, so he could only nod and said, "Yes." He took the secret key.

"The King of the Stone, your face seems a little abnormal. Is there any problem?" The King of the King of the King said in surprise. (To be continued, please search for Astronomy, the novel is better and faster!
