Looking back, it was all like a fairyland.

The area surrounding the doorway was filled with tall trees, some much taller than the others, blocking out all light. The forest was thick with mist, making it seem serene and quiet, with barely a sound, not even the faintest shadows.

As everyone approached the door, their pupils widened slightly. The ancient door had clearly only recently been placed there, yet it had already blended in with its surroundings. The patterns on it bore the marks of time, and moss had already crept upwards along the base. The patterns on it resembled a sun, a simple bird spreading its wings within it, its three legs a testament to its status.

The mirage dragon subconsciously wanted to move forward and touch it, but its arm passed through the door.

"What are you thinking? We're not here. Do you want to possess every treasure you see?" The old goat's mocking voice came from behind the mirage dragon.

"Tch, don't you know you can't help yourself? Do you even know what a grotto-heaven means with your two ounces of brain?" The mirage dragon immediately retorted.

Before they could say anything more, a deer suddenly darted out from the bushes. The deer cautiously surveyed its surroundings, listening carefully. Not noticing anything unusual, it slowly approached the door. Of course, the deer had no idea what the door was for; it simply wanted to nibble on the tender grass surrounding it. It wasn't sure if it was the door's function, but it must have been, as the grass around it was much tenderer than outside.

After only a few bites, however, the deer spotted the door. The door seemed to hold an inexplicable attraction for the deer. It stared at the door motionlessly, then lifted its hoof and subconsciously took a step. This step seemed to trigger some mechanism, and the seamless door opened a crack.

The next moment, the deer vanished from its spot. In the blink of an eye, as if it were an illusion, the door returned to its original state, unchanged.

But spectators like Su Mu are not simple people.

"They went in already?" The mirage dragon was somewhat incredulous.

But the old goat burst into laughter.

"What are you laughing at?" The mirage dragon glared at the other party.

"I'm laughing at you! You do resemble that deer, but if your true form were there, you might have gone in too."

"You!!"

Su Mu shook her head and looked at Lu Wu: "You prepared this for us, right? What's unusual about this cave?"

Lu Wu, who had been completely indifferent, suddenly fell silent upon hearing Su Mu's words. For a moment, he didn't know whether to answer or not. He didn't know either—his memory had been erased. But he felt that this was something he could do, sacrificing the small to protect the big.

He had already considered this scenario: the other party would definitely not give up, but not giving up would likely cause problems for his plan. Better to open it up than to block it. The moment he saw this door, he had already made a guess, because it was different.

"I...don't know," Lu Wu replied, forcing a smile.

However, Su Mu didn't believe it, nor would she be foolish enough to knowingly walk into danger. Regardless of the truth, this door was impassable: "Cao Chen, try another door."

Cao Chen did not deny it.

The surrounding environment has changed.

"How did you know?" the Mirage Dragon asked curiously.

"Are you stupid? The aura of fate on this is so strong it's practically overflowing; it's obviously intentional. Cao Chen's skill level is such that he could find it on the first try; it's that simple. Why bother throwing it out in different places? It's just redundant." The old goat explained, then gave the mirage dragon a disdainful look.

Mirage Dragon: ......

He himself began to doubt whether he had been living in comfort for too long, causing his brain to degenerate. He didn't even know something that even a goat could see.

But he soon realized that the goat was just being a hindsighter, simply looking for an excuse to taunt him. It wasn't that the old goat disliked the mirage dragon, but rather it was a subconscious move—the two of them were so used to bickering that they felt something was missing without a few words. There was nothing wrong with that, it just lightened the mood.

After hearing what Su Mu said, Cao Chen once again began searching for another door. This time, it wasn't as easy as the first time. The various threads were tangled and the suspicious afterimages were as numerous as stars in the sky. He had to point them out and select them one by one.

This didn't faze Cao Chen; instead, it made him even more serious. In other words, he was enjoying it—after all, finding the door so easily made him both delighted and somewhat disappointed. It was too easy, too unchallenging. For him, this was what he truly wanted. The more difficult it was, the greater the sense of accomplishment when he finally got the answer.

As for not being able to find it? From the very beginning, Cao Chen had never thought of this. It must be said that those who entered the Dao were extremely confident.

While Cao Chen was looking for the whereabouts of another door, Su Mu was asking about the difference of that door.

Seeing that the plan hadn't been accomplished, Lu Wu stopped hiding it. He had still underestimated this group of people—how many of them were fools? Even the demons he had hung up were quite clever, it was just the difference in strength.

"The time inside that door is vastly different from the time outside."

Have you ever heard that a day in heaven is equivalent to a year on earth?

"Time seems to pass so quickly within that grotto-heaven. When you enter and then emerge, everything may have changed beyond recognition, hahaha."

This place truly deserves the title of a blessed cave, and is a great place to escape from the world. Time in the cave is much slower than in the outside world. A year spent inside could mean over three hundred years have passed in the outside world.

Lu Wu did not lie, nor did he bother to lie. After hearing his explanation, everyone suddenly realized what he had planned.

Lu Wu finished his explanation and fell silent. Seeing his plan completely ruined, he didn't want to meddle in it any more—the more he did, the more mistakes he made. It was better to let everything take its course, let the unknown determine everything.

As they spoke, Cao Chen had already found a clue. The afterimages were quickly pierced, much faster than at the beginning, until only three or four remained.

Cao Chen chose one of them, and the surrounding scenery changed, just as it had when they first encountered it. They arrived at a swampy area, withered branches and rotting trees, and a stench of decay filled the air. And within this swamp stood a door, half of it already engulfed, leaving the remaining half exposed.

"Found it." Cao Chen said with satisfaction, as if he had solved a difficult problem.

Lu Wu had no expression on his face, but he kept thinking: These people are so lucky...
