After all, this purple divine thunder is not afraid of a trace, and it can also kill the two of them.

Therefore, Yang Yu can only do this, and now he looks like he is seriously injured, just to protect them.

Yang Yu was absorbing the soul ring, so he naturally didn't know that Lin Xi and Lin Ying were looking at themselves and blaming themselves.

However, as the absorption time became longer and longer, Yang Yu's face became more and more excited, because he could feel the terrifying power contained in this Heavenly Thunder Root Soul Ring, which was simply terrifying.

The power of thunder is worthy of being the innate spirit with the top destructive ability of heaven and earth.

In this way, in Yang Yu's rather excited mood, the absorption of the soul ring gradually came to an end, and the absorption was almost over.

The red soul ring above Yang Yu's head also gradually became dim, but in Yang Yu's body, the soul power had skyrocketed, which was undoubtedly a good thing for Yang Yu, who had no time to practice soul power.

"Hum!" Ten minutes later, Tian Lei Gen's soul ring vibrated slightly, and then turned into a streamer of light, directly submerging into Yang Yu's body.

And Yang Yu's eyes that had been closed all the time also opened, and wisps of very terrifying light flickered under Yang Yu's eyes.

"Second Soul Ring...... Strong!"

Yang Yu felt the second soul ring in his body, and after feeling the two soul skills he gave Yang Yu, the excitement in his eyes skyrocketed.

Heavenly Thunder Root, a 100,000-year-old desolate alien species, among the soul skills given to Yang Yu, naturally one belongs to Thunder.

However, this thunder loneliness is a little unusual, it is not a terrifying thunder, but a method of cultivation.

The Thunder Emperor's Treasure Technique, a powerful treasure technique from "Perfect World", is one of the ten fierce ones with very strong attack power, and his original treasure technique is the Thunder Emperor's Treasure Technique, which is the strongest treasure technique that controls all the thunder in heaven and earth.

As for the second soul skill, it made Yang Yu cry and laugh a little, although this treasure technique was also extremely powerful, but it was a little beyond Yang Yu's expectations.

The Nine-Clover Sword Grass Treasure Technique, also from the Perfect World, is one of the three major sword arts, and its attack power is unmatched.

However, the soul skill that a Heavenly Thunder Root would give Yang Yu was indeed much beyond Yang Yu's expectations.

"Nine-leaf sword grass treasure technique, this is not needed for the time being, and after finding a suitable sword, I will ponder it carefully and use it as a big hole card. ”

Yang Yu stood up and patted the dust on his body, feeling very happy.

"Yang Yu, are you okay?"

Lin Xi and Lin Ying handed over Yang Yu and stood up, and immediately looked over with great concern.

"I'm fine, although I'm a little injured, but don't forget who my master is. ”

Yang Yu waved his hand, directly turned over his hand and took out an elixir and took it, his face was very flat.

"It's okay. The two of them finally breathed a sigh of relief, and their faces were much soothed.

"Let's take a good look, haven't you wanted to see it for a long time? Yang Yu smiled and waved his hand, and said with a smile while healing.

"We've seen it and there's nothing special about this place, except that the stones are stones. The two shook their heads.

"Really, why can I still feel something else? and it's strong. Yang Yu looked at the two of them, his brows furrowed slightly.

"It's nothing special, we just gave you the Dharma Protector, so we checked all around, only the ground and the walls. Lin Xi nodded and said with great certainty.

"No, in this cave, there is another aura that is even more powerful, and it is even stronger than the Heavenly Thunder Root. Yang Yu shook his head and began to walk around the cave.

"This cave...... There's really nothing special. ”

Yang Yu walked around, but he really didn't find the slightest special place or secret passage, but he did feel a very strong and familiar aura.

"No! This is the breath of thunder!" Yang Yu pondered for a long time, then suddenly raised his head and exclaimed.

"Thunder?"

Lin Xi and Lin Ying looked at Yang Yu suspiciously, "But, isn't Tianleigen already stupid by you?"

"No, the other thunder aura is much stronger than the Heavenly Thunder Root, and it is very pure. ”

Yang Yu shook his head, glanced around the cave, and without saying a word, he directly released his martial soul, and two soul rings, one black and one red, floated out.

"The Thunder Emperor's Treasure Technique, it's up to you. Yang Yu lit up the second soul ring and directly urged the Thunder Emperor Treasure Technique.

Speaking of familiarity and mastery of thunder, what could be more powerful than the Thunder Emperor's Treasure Technique?

"Found it!"

A few minutes later, Yang Yu's eyes lit up, and he looked at one of the walls of this cave in surprise.

"You follow me and flee at the first danger. Yang Yu looked at Lin Xi and Lin Ying and admonished, and then walked towards the cave wall.

Taking out the reverse halberd, Yang Yu didn't say much, and directly condensed the strongest blow and slammed it into the cave wall.

"Boom!"

In an instant, in the surprised eyes of the two sisters, Yang Yu and Lin Xi, the cave wall that should have been a solid wall suddenly cracked, turned into rubble, and spilled all over the ground.

"The formation naturally formed by heaven and earth?" Yang Yu walked into the hole that appeared, and suddenly let out a shock, which was very incredible.

"Formation?" Lin Xi and Lin Ying were both very puzzled, obviously not feeling anything.

"It can make heaven and earth automatically generate formation protection, and it is such a high-level phantom array, it seems that at the end of this cave passage, there are some incredible treasures. ”

Yang Yu apprenticed to Taishang Laojun, because he had the relationship of the Fire Ancestor Fu, so the three auxiliary means of alchemy, refining, and formation were all involved.

And the formation that Yang Yu broke just now to hide this cave is a phantom array, which makes people mistakenly think that the cave where Tianleigen is located represents the end of the Nine Poles Cave.

However, in fact, this is protected by the formation naturally generated by heaven and earth, and now the entrance to the cave in front of the three of Yang Yu is likely to lead to the end.

"Treasures?" Lin Xi and Lin Ying were suddenly pleasantly surprised.

"Yes, otherwise, this formation naturally formed by heaven and earth is not a phantom array, but a defensive array that no one can break. Yang Yu nodded, with a smile on his face.

In fact, Yang Yu didn't discover this phantom array at all, if he hadn't broken the entrance and broken the formation, Yang Yu wouldn't have found a phantom array at all, let alone discovered this entrance.

Everything, because of the Thunder Emperor Treasure Technique, Yang Yu was not looking for the entrance at the beginning, but the source of those thunder dao breaths, so he found this mouth by chance.

"Go in, there will be a treasure in it!"

Yang Yu nodded, very sure, because of the phantom array, Wade is to protect those things in this cave.

However, when the two sisters, Yang Yu and Lin Xi and Lin Ying, walked to the end of this entrance, their expressions were shocked again, and they looked at the space in front of them with long mouths.
