Hearing her sister's question, Nana immediately stepped forward and hugged Wu Luxuan's arm and said with a smile: "That's the case, I encountered a bottleneck in my cultivation, and Brother Nie Yun helped me break through." Look at my current strength, is it much stronger than during the day. ”

Nana said confidently, if it weren't for the fact that they were sisters, she would have thought that Nana wanted to challenge Uluxuan.

"I see, but why don't you practice during the day, so why do you have to come here in the middle of the night?"

Uluxuan still couldn't figure it out.

"The cultivation of a samurai is different from that of an elementalist and an archer, and he needs a quiet environment when breaking through the bottleneck, so he chose this time and this place. ”

Thinking that Nana's explanation made sense, Uluxuan didn't ask again. Everyone returned to Mingyue's cave together, and as the only man, Nie Yun was responsible for guarding the entrance of the cave.

After passing through the mysterious man, Nie Yun sat quietly at the entrance of the cave all night. Until dawn, it was very quiet, and I didn't even hear the sound of insects, probably scared away by Uluxuan's dozens of fireballs.

After having breakfast with the girls, Mingyue suddenly received a message from her teacher, saying that Wu Zu had been invited.

Nie Yun naturally didn't dare to delay, and immediately came to the Great Elder's cave mansion.

"Hehe, Nie Yun, you're lucky. Wu Zu is going to see you so soon, it seems that Wu Zu has a good impression of you, and I hope you can get what you need from Wu Zu. ”

The Great Elder still had that kind expression.

"Thank you for the Great Elder's good words, but Wu Ancestor is such a supreme existence, why do you want to see me?"

Nie Yun asked the doubts in his heart.

Hearing this, the Great Elder shook his head with a smile and said, "Wu Zu is indeed a special identity, but don't underestimate yourself, since Wu Zu wants to see you, then you will definitely know the reason for the Dao when the time comes." Don't waste time, I'll take you to see Wu Zu. ”

The Great Elder got up and walked towards the depths of the Cave Mansion, and Nie Yun followed behind the Great Elder. As he continued to go deeper, Nie Yun felt more and more incredible. No matter how you look at this cave, it is more than ten meters deep at most, but now I have walked nearly 100 meters, but I still haven't seen the end of the cave.

"You must have a lot of questions in your mind, don't worry, you'll know the Tao in the future. Okay, the Wu Clan is ahead, you go by yourself, and I'll send you here. ”

The Great Elder pointed to a dark cave in front of him and said, then turned and left. Nie Yungang wanted to ask about the situation inside, but when he turned around, he couldn't find any trace of the Great Elder, and he didn't know if it was because the witchcraft was too magical or because the Great Elder's strength was too strong.

Since he has arrived here, there is naturally no reason to turn back, although he doesn't know what the situation is in front of Lu Dao, but Nie Yun still walked in without hesitation.

As soon as he entered the cave, Nie Yun felt that the air inside was very viscous, as if he was not walking in the air, but in the water. Nie Yun could clearly feel the resistance of the air, and when his hands tried to move, he could also feel the resistance like a stream of water.

After walking in the pitch-black space for about ten minutes, Nie Yun noticed that a staircase appeared in front of him. After walking up the stairs for dozens of floors, I finally saw a glimmer of light, which was a purple light, and I felt a sense of déjà vu.

Finally walking up the ladder at the back of the ladder, Nie Yun suddenly felt a light pressure on his body, and the previous feeling of restraint like being in the water disappeared, and everything returned to normal.

Nie Yun looked up and saw a purple ball of light suspended in the air, and the light he had seen before came from this ball of light.

"Welcome, young man!"

At this time, a strong voice reached Nie Yun's ears, Nie Yun looked around, but did not find the source of this sound, because this voice came from all directions, and it was impossible to locate it at all.

"Don't look for it, you can't see me, it's just a spiritual clone of mine, a phantom. ”

The voice rang out again.

"Could it be that you are the Witch Ancestor?"

Nie Yun asked.

The voice was silent for a moment, as if thinking about something, before he said, "Wu Zu is long gone, but if you call me that, it's okay." ”

This was tantamount to admitting his identity, but from his tone, Nie Yun could tell that this once powerful existence was also the same as the strong man he had met before, he was extremely seriously injured, and was already in a state of deep sleep or on the verge of death.

"I wonder what happened to the ancestor of Wu Zu looking for me, a nobody?"

Nie Yun actually had some doubts in his heart, as soon as he came here, Wu Zu wanted to see him, and it seemed as if this Wu Zu had been waiting for him.

"I don't know how long I've been in this place, and I don't know how many centuries I've been asleep, but when you first set foot in our Wuzu territory that day, I sensed the breath of some old friends. I'm here to find out what happens to my old friends. ”

Hearing this, Nie Yun was confused again. Nie Yun still remembered that when he was in the Treant Clan, the Treant Clan's Tree God said so. Later, he met the powerful divine beast in the secret realm under the Lion King Palace, and also said that he felt the breath of an old friend on his body, and then gave himself the ability of a double sea of qi.

Through these inferences, Nie Yun came to the conclusion that these powerhouses were all of the same era and were familiar with each other. But due to some special reasons, they are all seriously injured and are recovering in a secret place.

As for the cause of the injury, Nie Yun deduced that it was related to the disaster that Master Da Ran said last time, it was something that happened ten thousand years ago, those demons were powerful, so they caused countless powerhouses in the Shenlong Continent to fall or be seriously injured.

"Senior Wu Zu, I don't know what you mean by old friends, what is related to your friends?"

Nie Yun has always wanted to figure out these things, what connection he has with those ancient powerhouses, and why he will carry their aura.

"I think you saw them a while ago. And I can see that they have a good impression of you and have given you a little favor. ”

It seemed to be talking about his old friend, and the voice became a little excited, and finally had some feelings.

"Senior Wu Zu, I remember the first time I met Senior Tree God, he said that he felt two familiar breaths from me, but when I asked him, he didn't tell me. I wonder if the predecessors of the Dao Witch Ancestor also discovered that there is any hidden aura on my body?"

Nie Yun still didn't give up, hoping to get some useful news from Wu Zu, although it was not very likely that he knew the Dao.
