What came into view were seven icy pillars, and the ground was made of rare mysterious ice. Mi Xiaojing had just stepped on it and almost froze. He quickly activated the power of the Starry Sky to dispel the cold.

Wang Weijun exclaimed in surprise, "Huh, this treasury is interesting! It doesn't seem to be built by current cultivators. It looks more like a relic that has been refurbished."

Yong Ji explained to Mi Xiaojing, "This is an ancient cultivator's training ground, most suitable for ice-attribute cultivators. After generations of exploration by the sect's experts, it has been thoroughly excavated. Due to the extremely powerful prohibition formations inside, it has been used as the sect's treasury."

In fact, this was also the cultivation ground of the Azure Descent Immortal Maiden. An ancient ice-attribute technique was once discovered here. It has been passed down through generations, and talented disciples would practice here.

Currently, only the Azure Descent Immortal Maiden in the sect could successfully cultivate this technique. The requirements of this technique were quite high, and those who could cultivate it were extremely rare.

Ever since the Azure Descent Immortal Maiden advanced to the Elemental Infant stage, this place became her cultivation ground. She was also responsible for protecting the sect's treasury.

The surroundings were blanketed in white, as if they were in thick clouds. Interestingly, these clouds only rolled around the edges, leaving a patch of ground in the middle.

The Azure Descent Immortal Maiden coldly warned, "Don't try to probe the surrounding ice fog. It's condensed from mysterious energy and is very powerful."

Mysterious energy was a high-end material for refining tools. It was surprising that it was used as a defensive measure here. This fact made Wang Weijun exclaim in surprise. Before touching it, who would know that the ice fog was condensed from mysterious energy?

Wang Weijun said, "I didn't expect the Heart Sect to have such secrets. Good, good!"

"What do you mean?"

"Hehe, I mean that this place might have been a secret ground of a great power or an ancient sect a long time ago. The Heart Sect might still have undiscovered places, relics, ancient relics, and so on. Every time they are discovered, they cause a bloodbath. If it's a relic of an ancient sect, it's even more so."

"You mean, there are overlooked relics here that the sect hasn't discovered?"

"Smart lad, that's exactly what I mean!"

"That's impossible. Even if the sect only has Elemental Infant stage cultivators now, it doesn't mean there were no experts in the past. How could there be any oversights?"

"Maybe, I'm just saying maybe. There might be, but there might not be!"

Wang Weijun once again raised his head arrogantly.

"Alright, you've said both good and bad things. What else can I say?"

"Ah, what kind of talk is that!"

Mi Xiaojing couldn't help but want to laugh. Arguing with the old man was becoming one of his pleasures.

"Human talk!"

"Are you saying that I'm not speaking human language?"

"I didn't say that, you said it yourself!"

"What did I say? What did I say? I didn't say anything!"

Wang Weijun almost cursed out loud, but he stopped himself. He had a shadow in his heart and didn't want Mi Xiaojing to have a bad impression of him.

"Little rabbit? What do you mean?"

This time, Wang Weijun ignored him. He found that the more they talked, the more off-topic they became.

At this time, a group of people began to follow the Azure Descent Immortal Maiden inside. The surrounding ice fog was still rolling, and a path formed in front of the Immortal Maiden. She cast a magical technique and immediately opened the passage.

Mi Xiaojing noticed that the passage was going downward. The seven ice pillars gradually disappeared in the rolling ice fog. The surroundings were silent, and no one spoke.

Everyone's feet were half a foot above the ground. They didn't dare to stay on the ground for too long. The cold from the ground could penetrate their bodies. Even if they circulated their cultivation, it was still extremely cold. Everyone chose to hover above the ground.

In this way, the way everyone moved was quite strange. They floated forward.

Following a winding path, no one dared to overstep or rush around. They followed the person in front, matching their pace, and moved forward.

Mi Xiaojing noticed that ice pillars would occasionally appear around them. Sometimes there was one, sometimes three or four. Wang Weijun had been observing from the Heart Tower. After a while, he suddenly said, "It's not the Great Yan Mysterious Heaven Formation, it's not that advanced. This is the Small Mysterious Heaven Formation!"

"Uh, how do you know?"

It can be hard to make great work when its stolen from bit.ly/3iBfjkV.

"To be precise, it's the Mysterious Ice Formation, with the variations of the Great Yan Forty-Nine!"

Mi Xiaojing was confused, "What do you mean? I don't understand."

"Nonsense, of course you don't understand. This is an ancient formation, it's no longer used now."

"Is it very powerful?"

"Not really. After development, it was found that this formation had fatal flaws and was completely broken by people."

"I see, then why is everyone so cautious? They're afraid of touching the formation?"

"With your cultivation levels, of course you would be careful. Having flaws doesn't mean you can break it. The person who set up this formation should have a decent cultivation level.""Alright, you're always right no matter what."

In fact, Mi Xiaojing still admired Wang Weijun a lot. This old man really knew a lot.

"Because I am right!"

Wang Weijun acted arrogantly again.

Mi Xiaojing found it amusing, but he had to admit, this old man was indeed very impressive. Of course, his habit of arguing was still there: "Even if you're right, can you break this formation? Or are you just talking?"

"Ah, nonsense!"

Wang Weijun couldn't help but get angry again. He felt underestimated. But then he became helpless because he could only stay in the Mantra Banner and couldn't get out.

Moreover, he no longer had a physical body. Even if he could get out, what could he do? If he still had his physical body, breaking this Mysterious Heaven Formation would be a piece of cake.

As for breaking the formation now? Forget about it!

For some reason, every time the old man got angry, Mi Xiaojing wanted to laugh.

"Alright, alright, I was just joking. You're so old, yet you still get angry so easily."

Wang Weijun was left speechless. This little rascal liked to make him angry, but then came back to comfort him. It was simply unbearable.

The passage was quite long. They walked for about fifteen minutes before they saw seven ice pillars again.

Mi Xiaojing couldn't help but ask, "Old man, why do I feel like we're back where we started?"

"Oh, well done! You actually noticed that we're back where we started. Impressive!"

"There are seven ice pillars here, just like before. The only difference is the location. We should have been standing over there."

The difference was no more than twenty meters, but in a formation, every position had its own function.

"If we don't walk this way, we'll trigger the Mysterious Heaven Formation. That would be fun, haha!"

Wang Weijun suddenly burst into laughter, which confused Mi Xiaojing. What was so funny? Was the old man going crazy?

After laughing for a while and seeing that Mi Xiaojing didn't react, Wang Weijun suddenly lost interest. He sat back on the heart tower and said listlessly, "We should be almost there."
