"A shocking secret? What a shocking secret?" Li Feng asked.

"Senior, as long as you spare my life, I will tell you." said the old man in gray.

"Do you think you are qualified to negotiate terms with me now?" A sneer appeared on Li Feng's lips: "Now you have only one choice, and that is to tell me obediently what this shocking secret is."

"Senior, I just want to save my life." The old man in gray shook his head.

"Don't overestimate your capabilities." Li Feng sneered.

Whoosh!

The next moment, Li Feng waved his hand, and a spatial blade shot at the gray-clothed old man's dantian, directly destroying the gray-clothed old man's dantian.

"Are you qualified to negotiate terms in front of me?"

Li Feng snorted coldly and used the ecstasy technique on the old man in gray.

"Tell me, what is the shocking secret." Li Feng said.

"This shocking secret is none other than the mystery of the disappearance of the Ghost Immortal Clan." said the old man in gray.

"The mystery of the disappearance of the ghost fairy clan?" Li Feng's eyes flashed.

The ghosts and immortals also disappeared in ancient times.

This place of flames also existed in ancient times.

Is there a relationship between the two?

But this time, one of his purposes in going to the Land of Fire was to find the Ghost King's Shield.

Now he heard the news that there was a clan of ghosts and immortals in the land of Yanju, which made him very happy.

Because there is news about the Ghost Fairy Clan, there may be news about the Ghost King Shield.

This is a good thing for him.

"What is the mystery of the disappearance of the Ghost Immortal Clan?" Li Feng asked.

"I don't know, but there is news about the disappearance of the Ghost Immortal Clan in the Land of Flame." The old man in gray replied.

Li Feng's eyes flickered and he asked a few more questions.

After asking these questions, Li Feng killed him with one palm.

"run."

When several warriors nearby saw this scene, they knew that Li Feng would not let them go, and ran outside quickly.

"Want to run?"

Li Feng sneered.

Swish, swish, swish...

Space blades swept away one after another, directly killing these warriors.

"Now this guy is saying that there is a mystery about the disappearance of the Ghost Immortal Clan in the Land of Flame. Previously, the villain said that the Ghost Immortal Clan is resurrected... Is there any connection between the two?"

At this moment, Li Feng thought of what the villain said to him in front of Bailing Palace.

I also thought about the news about the ghost fairy clan that I got in the Tailing Realm.

Finally, I thought of the ghost fairy clan in the Ice and Thunder Abyss.

"No matter what secrets the Ghost Immortal Clan has, for me, as long as I find the Ghost Immortal Clan's clan-suppressing artifact and rescue Nangong Xin, Chen Miaoling and Liu Ruyan, that's enough. Everything else is irrelevant."

Thinking of this, Li Feng's eyes fell on the medicine shelves on both sides of the hall.

Those medicine shelves are filled with elixirs and even some elixirs.

Now that the warriors here have been dealt with, it is time to get these elixirs and elixirs.

Whoosh!

Thinking of this, Li Feng's figure flashed and appeared in front of the medicine shelf.

"Um?"

"This secret technique of sealing the elixir..."

Li Feng's eyes fell on the jade box on the medicine shelf, and a look of surprise flashed in his eyes.

The elixir can be kept effective if stored in a jade box.

However, even if it is a jade box, it will not maintain the efficacy of the medicine for a long time. Therefore, this requires the secret spirit sealing technique.

There is not just one spirit-sealing technique.

This spirit-sealing technique is similar to a martial art, and has many levels.

The higher the level of the spirit-sealing technique, the better the effect.

Li Feng had the alchemy memory of Qiu Xuefeng, a saint-level alchemist, and naturally also obtained Qiu Xuefeng's spirit-sealing technique.

Until now, he has never seen a better spirit-sealing technique than his.

However, at this time, Li Feng saw a spirit-sealing technique that was better than his spirit-sealing technique.

If his spirit-sealing technique can preserve elixirs for one million years, then the spirit-sealing techniques on these jade boxes can preserve elixirs for at least ten million years.

"Is this the method of Emperor Yan, or the method of Yan Ju?"

Li Feng murmured.

Then I thought about it, both Yan Emperor and Yan Ju should be using the same method.

"However, with this spiritual technique, the elixirs in these jade boxes should be useful, right?"

Li Feng picked up a jade box, opened it and looked at it.

The Land of Flame has existed for an unknown number of years.

Therefore, no matter how powerful the spirit-sealing technique on the jade box is, Li Feng cannot guarantee that the elixir in the jade box will still be useful.

However, after opening the jade box, Li Feng looked down and his expression changed.

Because there is nothing in this jade box.

"The elixir here is gone? Is it just that the elixir in this jade box is gone? Or is it that all the elixir in the jade box here is gone?"

"It probably wasn't taken away by anyone. If it was taken away by someone, there would be no jade box left."

Thinking of this, Li Feng opened each jade box and looked at it.

At first glance, Li Feng breathed a sigh of relief.

Although many of these jade boxes are empty, three to four out of ten contain elixirs.

After checking more than a dozen jade boxes, Li Feng did not continue to check, but directly collected these jade boxes and the jade bottles containing elixirs on the medicine shelf into the Xuanling Realm.

An hour later, after sweeping up the elixirs and elixirs on the medicine shelves in the main hall, Li Feng swept towards the depths of the main hall.

Deep in the hall is a passage paved with white marble.

Li Feng looked around and then entered the passage.

"This is……"

After wandering in the passage for a quarter of an hour, Li Feng saw stone chambers appearing on both sides of the passage.

Seeing these stone chambers, Li Feng's eyes flashed with surprise.

The reason why he came here was because he wanted to go to other places through the hall just now.

"Are there any treasures in these stone chambers?"

A flash of surprise flashed in Li Feng's eyes.

Whoosh!

At that moment, Li Feng's figure flashed and came to a stone room, and he slapped the stone door with his palm.

"Um?"

The next moment, a flash of surprise flashed in Li Feng's eyes.

He didn't expect to push the stone door with his strength, but the stone door wouldn't move at all.

Is there a switch on this stone door?

However, after scanning around, I couldn't find the switch.

"what to do?"

"If we can't find the switch, I'm afraid this stone chamber won't be able to be opened."

"Although I don't know what is in this stone chamber, it may not be without treasures."

Hesitation flashed in Li Feng's eyes.

Li Feng knew that there were many chance treasures in Yanju Land, but the dangers here were far beyond what they could withstand. Therefore, it was impossible to obtain all the treasures and opportunities in Yanju Land.

So, now he faces two choices.
To be continued...
