Ye Feng stopped talking nonsense, turned around and faced away from them, meditating and practicing his internal energy.

It was already past midnight.

The sandstorm grew stronger and stronger, the yellow sand in the air was so powerful that it made a howling sound, as if giant yellowish-brown dragons were wandering in the wind.

"What bad luck, we actually ran into a sandstorm," Night Wind said, frowning.

Wu Qingyu said, "How about we dig a cave here to take shelter from the sandstorm?"

"Good idea."

Night Breeze nodded and took out a talisman, which he then cast.

A cave suddenly appeared in the sand dune in front of them, and as the talisman went deeper, the cave became deeper and deeper.

Suddenly, the entire sand dune seemed to tremble.

The sand dune collapsed!

Night Wind was secretly annoyed; when you're down on your luck, even drinking cold water can cause problems!

However, the collapse of the sand dunes is not incomprehensible. Sand is naturally very fluid, and Ye Feng used talismans to dig a hiding cave while a sandstorm was attacking from the outside.

The collapse of the sand dunes was therefore to be expected.

Seeing that the sand was about to bury Wu Qingyu and her son Lü Ming, Ye Feng quickly opened his true energy shield to protect them.

Suddenly, their footing gave way, and Ye Feng, Wu Qingyu, and Lü Ming uncontrollably fell down with the sand.

It was pitch black everywhere, a darkness so deep you couldn't see your hand in front of your face. This was nothing to Ye Feng, but it was a different story for little Lu Ming.

So Ye Feng carried Wu Qingyu and Lü Ming out of the sand and then shone a bright light.

This is the Bright Light Technique, one of the most common martial arts skills, which can transform true energy into bright light to provide illumination.

Looking at the long passageway in front of him, Ye Feng's face showed a look of doubt.

"Where have we ended up?" Night Wind muttered to himself.

"Could it be that there's a tomb under that sand dune, and we've fallen into it?" Wu Qingyu asked curiously.

“That’s possible; the structure here does indeed look a lot like a tomb,” Night Wind said.

Now a new problem has arisen.

They decided to stay here to avoid the sandstorm and leave after it subsided.

Or should we explore this underground tomb?

After a moment's thought, Ye Feng made up his mind to explore the tomb!

Since we're already here, how can we not check if there's anything good inside?

Even without anything good, it can still satisfy your curiosity.

Then Ye Feng smiled and said, "Madam Wu, would you be interested in exploring this tomb with me?"

“This…” Wu Qingyu hesitated.

Wu Qingyu was also very curious about the tomb, but she felt it was better to avoid getting involved.

It would be difficult to handle if there were any dangers inside the tomb.

If she were alone, she wouldn't think so much, but she also has a child with her.

Therefore, one must be cautious.

“If you’re not interested, then you can wait for me here. I’ll go deeper in and take a look myself,” Night Wind said.

Upon hearing this, Wu Qingyu quickly said, "Young Master Ye, what will we do if you leave?"

"You're a True Essence Realm martial artist, you can't be without the ability to protect yourself," Ye Feng said.

Wu Qingyu bit her lip, her expression still full of worry.

After a moment, she gritted her teeth and said, "Let's explore this tomb together. I think it's safer to be with you, Young Master Ye."

"In that case, let's go," Ye Feng said with a smile.

Night Breeze walked deeper into the passageway, with the bright light swaying gently beside him, illuminating a large area around him.

Wu Qingyu quickly grabbed Lü Ming's hand and followed closely beside Ye Feng, as if only in this way could she feel safe.

Murals began to appear on both sides of the passageway.

These murals are very simple, with rough lines outlining the general image in just a few strokes, and they are not colored.

Even so, Ye Feng still managed to glean some information from these murals.

These murals, taken together, tell the story of a young man's journey to seek immortality and enlightenment.

This young man traveled to famous mountains and rivers, and finally found a master to become his apprentice. He became a martial artist and studied alchemy, eventually becoming a Saint-level expert and a tenth-grade alchemist.

Such a person would certainly not be an unknown nobody, even in the entire Tianluo Great World.

However, Ye Feng didn't know much about the history of the Tianluo Great World, so he couldn't guess who this person was.

Further on, the murals disappeared.

The passageway has come to an end.

However, Ye Feng and Wu Qingyu were blocked by a bronze door.

The bronze door has a rather complex array, and its defensive capabilities are quite good.

Ye Feng tried, but found that he couldn't force his way through with his current strength.

After all, Ye Feng's injuries have not fully healed, and he can only exert strength equivalent to the peak of the Divine Travel Realm at present.

If Ye Feng's prediction is correct, this underground mausoleum is the tomb of that Saint Realm expert, then this bronze door must have been forcibly broken open by at least a Transcendent Realm expert.

But just because the Night Wind can't do it doesn't mean that the Blazing Heaven Wheel and the Mysterious Heaven Whip can't.

As long as I summon the Blazing Heaven Wheel or the Mysterious Heaven Whip, I can easily break open this bronze door in front of me.

But Ye Feng didn't do that. He carefully studied the bronze door, trying to break the formation on it and enter through normal means.

There is a recess on the bronze door, and that hemispherical recess is the key to the formation.

It looks like we should start here.

"Young Master Ye, can you open this bronze door?" Wu Qingyu asked.

“I’m researching it,” Night Wind said.

After a moment, the night breeze finally showed a hint of joy.

“I know how to open this bronze door now,” Night Wind said with a smile.

"How do I turn it on?" Wu Qingyu asked immediately.

"It's too complicated to explain, just watch me demonstrate," Ye Feng laughed.

Then Ye Feng sat down cross-legged, took out a weapon-refining furnace, and began refining weapons.

Wu Qingyu and Lü Ming watched curiously from the side, and Ye Feng's weapon forging did not take too long.

Only half an hour later, Ye Feng finished refining the weapon.

With a bang, the furnace lid of the weapon-refining furnace opened, and a small, silvery ball flew out. This ball was covered with intricate patterns and had some raised bumps on its surface.

Night Breeze put away the refining furnace and injected his true energy into the small ball, causing array circuits to appear on the surface of the silvery ball.

When the night wind pressed the small ball into the recess on the bronze door, the entire bronze door began to shine with a dazzling light.

The array circuits flowed and fluctuated, passing through the small silver sphere, becoming perfectly seamless without any gaps.

It's obvious that the small ball crafted by Night Wind has completed the entire bronze gate!

Seeing this, Wu Qingyu's face showed an expression of disbelief. She really did not expect that Ye Feng could use such a clever method to open this heavy bronze door.
