The mysterious grotto that Lin Wan talked about is just above the glacial lake not far away.

Mu Feng stood at the entrance of the grotto, his face full of doubts.

There is clearly a glacial lake at our feet. Although it has been frozen for who knows how many years, there shouldn't be a grotto in the middle of the glacial lake!

Based on this alone, Mu Feng knew that this grotto was not simple and must contain secrets.

"Have you ever been in before this?"

Mu Feng looked at Lin Wan and asked. Cold wind kept blowing out of the grotto. This wind was actually colder than the ice and snow outside. This could not be an ordinary grotto!

Lin Wan shook her head, "As soon as I discovered this grotto, I encountered those barbarians and had no time to enter."

Mu Feng raised his eyebrows, then took out the Dragon Blood Sword and threw it directly into the grotto.

The Dragon Blood Sword flew into the grotto under Mu Feng's command and kept moving forward.

There didn't seem to be any questions along the way. Just when Mu Feng wanted the Dragon Blood Sword to go deeper, the connection with the Dragon Blood Sword was suddenly severed.

"How can it be!"

Mu Feng exclaimed, his soul seemed to be shocked, and he lost contact with the Dragon Blood Sword.

There is definitely something extremely terrifying hidden in this grotto, otherwise it would be impossible to cut off the connection between Mu Feng and the Dragon Blood Sword.

"Want to go in?"

Lin Wan looked at Mu Feng with a solemn expression and asked. It seemed that this grotto was more dangerous than they imagined.

Mu Feng hesitated for a moment, then nodded, "Go in, but follow me closely, it's not easy inside."

After Mu Feng finished speaking, he directly took Lin Wan's hand and walked into the grotto. As soon as they stepped into the grotto, the cold made them shiver.

At their current state, they should have ignored the cold, but they could really feel the cold in the grotto!

"This grotto is really weird."

Mu Feng raised his eyebrows, and then flames erupted from his palms, making the two of them feel much better.

The two of them kept going deeper and didn't see anything weird along the way.

"This seems to be an ordinary grotto."

Lin Wan said, they had walked several kilometers, and there was always a road ahead as if there was no end.

If we continue walking, is it possible that we will have to go beyond the ends of heaven and earth?

Mu Feng stood there and was deep in thought. This cave could never be that deep, but they had indeed been inside the cave all along, and the scenery was the same along the way.

"Illusion?"

Mu Feng hesitated to speak. If this grotto was unreal, then everything would make sense!

"Illusion?

Could it be that we have been under an illusion since we entered the grotto?"

Lin Wan couldn't believe it. If he had been under an illusion since he entered the grotto, then the illusion was so superb that the two of them didn't notice it at all.

Mu Feng looked above his head, and the light shone into the house through the cracks in the stone. If the grotto was really that long, it would be impossible for sunlight to shine in. Then it could only be an illusion.

Mu Feng immediately sat down cross-legged, and his spirit began to explore the entire grotto.

To Mu Feng's surprise, his soul could only explore a distance of one hundred meters.

If it wasn't for the grotto that restricted the soul, then it could only be that the grotto was only over a hundred meters deep.

"There shouldn't be anything wrong. This is an illusion. We will probably stay where we are."

Mu Feng stood up and took a breath and said, "I didn't expect that after so much effort, I finally concluded that I was under an illusion. It was really funny."

Lin Wan frowned and asked, "So can this illusion be broken?"

Mu Feng smiled, and then the Three Spirit Heavenly Flames in his palm continued to expand, "I'll give it a try."

As Mu Feng waved his palm, the Three Spirit Heavenly Flames spread crazily towards the front and rear, filling the entire grotto.

After burning for a while, the two heard a miserable roar.

Mu Feng immediately put away the Three Spirit Heavenly Flames, and then slashed out with Feng Zhujian, aiming in the direction of the sound!

Hearing a crisp sound, Mu Feng raised his hand to summon his sword, and the Phoenix Candle Sword and Dragon Blood Sword returned to his hand together.

When the two looked forward again, they found a short old man looking at them eagerly. This old man was not very strong and was only in the middle stage of Ten Thousand Dao Realm.

But Mu Feng felt a strong threat from this old man. The old man was definitely not as simple as he seemed!

"I've met senior."

Mu Feng respectfully cupped his fists.

The old man glanced at Mu Feng, and then said breathlessly, "What are you two little kids doing on my territory?"

Mu Feng smiled and said, "Senior, we just happened to walk here. We have no intention of becoming enemies with senior."

The old man nodded after hearing this, "If that's the case, then leave quickly before I'm angry."

Mu Feng took a step forward and asked, "May I ask your senior's name?"

Mu Feng's words made the old man alert again, and a scroll appeared in his hand.

If Mu Feng guessed correctly, this scroll should be an extremely terrifying killing array.

The illusion just now should be the illusion array set up by the old man.

In other words, the old man in front of him is probably a spiritual formation master with extremely terrifying strength! Spiritual formation masters of this level are extremely rare in Juetian City.

"Senior, if it's not convenient for you to tell me, then I won't ask again."

Mu Feng smiled at this, he couldn't force people to say their names.

The old man waved his hand and said, "Boy, don't make small calculations. Old man, I have lived for more than a thousand years. How can these small calculations hide from my eyes?"

Mu Feng grinned and said, "I'm just curious about senior's identity, not trying to trick senior."

The old man snorted coldly, "No matter what your purpose is, leave quickly. You can't come here."

When Mu Feng heard the old man's words, he couldn't help but look deeper. It seemed that the old man was protecting or suppressing something, otherwise he wouldn't have laid out such a high-level illusion array.

"Well, let's say goodbye."

Mu Feng smiled and said, the two were about to turn around and leave, but the old man stopped them, "Wait!"

Mu Feng and Lin Wan looked back curiously, "Senior, do you have anything else to do?"

The old man hesitated for a while, then took a deep breath and said, "I can't leave here. Can you do something for me? If you complete it, I will be rewarded generously."

Mu Feng thought for a while and smiled, "I don't even know your senior's name. If I agree to your request easily, wouldn't it be easy to get into trouble?"

The old man waved his hand and said, "I won't let you do anything stupid, I just want to bring something back."

Mu Feng did not speak, but looked at the old man with a smile. It was not like he was asking for help, so of course there was no need to worry.

Seeing that Mu Feng still refused to give up, the old man could only sigh and said, "There is nothing we can do against you, little guy. My name is Peng He, and I am the elder of Tianzhen Sect."

"Tianzhen Sect?

Wasn’t it destroyed decades ago?”

Lin Wan said in surprise that she learned a lot about Juetian City in Fanglou and saw the news that the Tianzhen Sect was eliminated.

Moreover, the force that destroyed the Tianzhen Sect was none other than Prince Jing’s Palace!

Peng He smiled and said, "The little girl knows quite a lot. Yes, I am the only one from the Tianzhen Sect who has survived."

Mu Feng looked at Peng He. Peng He was only at the Ten Thousand Dao Realm, but he was an elder of the Tianzhen Sect. It seemed that Peng He had very high attainments in the spiritual formation, otherwise he would not have such a status in the Tianzhen Sect.

"Boy, I have informed you of my identity. Can you agree to my request now?"

Peng He squeezed the scroll in his hand, and when he planned to reveal that he was from the Tianzhen Sect, he was ready to use the formation.

If Mu Feng and Lin Wan were from the hostile forces of the Tianzhen Sect, he would release the scroll without hesitation and kill the two!

Mu Feng glanced at the scroll in Peng He's hand, raised his lips and smiled, "Senior, a five-star divine formation cannot kill us."

Peng He opened his eyes wide in surprise. Mu Feng actually saw that the spiritual array in his hand was a five-star divine array!

"You have sharp eyes, but the five-star divine formation is enough to kill those in the early stage of Seeking Dao Realm. Even the strong ones in the middle stage of Seeking Dao Realm can't resist. How do you get the confidence?"

Peng He smiled and said that he was very confident in his formation. As long as Mu Feng and Lin Wan were trapped by the formation, they would definitely not escape death.

Mu Feng smiled, then pulled out the Dragon Blood Sword and struck out with one strike!

The terrifying sword intent gathered into a storm and instantly penetrated the strong man behind Peng He.

When the storm of sword intent leaped past Peng He, Peng He trembled unconsciously. Mu Feng's sword just now could definitely break an ordinary five-star divine formation!

"You kid, you are not simple!"

Peng He narrowed his eyes. He didn't expect Mu Feng to be so powerful!

Mu Feng smiled and said, "I don't want to break up with the seniors. The Tianzhen Sect was destroyed by Prince Jing's Palace. We can stand on a united front."

Peng He raised his eyebrows and asked, "Which force are you from?"
