"I want to know what, can I have this thing in the True Illusion Palace?" said Fen Fen glaring.

"Well, you don't need to be too specific, just give me a general direction. Yun Yun said.

"Give you a piece of the sea and let you go to the needle?" said Fenfen.

"I have the patience to find a needle. Yun Yun said.

"There are only two directions that I know. The first direction is literally, to find the source spirit from the fairy spirit stone, but none of the hundreds of billions of fairy spirit stones in my True Illusion Palace have a source spirit, which shows how low its probability is.

The second direction is in the Desolate Demon Sea, and it is rumored that there are 70,000 fairy spirit stone mines born from the early stage of the formation of the fairy spirit realm in the depths of the demon sea, and each spirit stone mine has at least one fairy spirit stone source spirit. After Fen Fen finished speaking, Yun Yun fell into deep thought.

"It seems that we can only go to the Demon Sea once. After a moment, Yun Yun muttered to herself.

"Isn't it? You really want to find it? Although that thing is scarce, and the entire chaos is only 194,100, it is of no use to monks above the True Immortal, I see that your breath is almost True Immortal, right?

"Do you think I want to! I wouldn't be able to reach the True Immortal without it!" Yun Yun glared.

"Why? True Immortals and Immortal Venerables don't need to be enlightened, just accumulate immortal spiritual power, what's so difficult?" Fen Fen wondered.

"Don't bother to explain, guess for yourself. Yun Yun said and was about to leave.

"Wait a minute! Bring this!" Fen Fen called Yun Yun and threw a jade slip.

"The map of the Desolate Demon Sea?" Yun Yun muttered after catching it.

"Without it, you wouldn't be able to find the true bottom of the sea in that rugged and unusually rough seabed. Fen Fen said.

"It's strange, since someone can explore the map, why are those spirit stone mines still there?" Yun Yun wondered.

"In the beginning, there were no Demon Sea Giants there, and the first explorers somehow released them, which is a map left by the survivors at that time. Fen Fen explained.

"Oh, thank you, I forgive you for lying to me last time. Yun Yun said.

"How many years has it been, five billion years or six billion years?"

"More than that, it seems to be more than 10 billion years old? My concept of time is also very shallow, I wonder if I will become a big fool like you in the future. Yun Yun said and left the Alchemy Hall.

Returning to the coastline of the Demon Sea alone, she hid herself with the power of the rules and walked into the sea.

Although this method is no different from covering one's ears and stealing bells for fellow immortal-level monks, it is enough to deal with these monsters without spiritual intelligence.

There is nothing special about the sea water here, it is just ordinary sea water, but even so, when diving to a certain depth, Yun Yun is still affected a lot.

First of all, there was no light at all, not to mention glowing creatures, not even a single bacterium.

This greatly affected Yun Yun's perception, because she didn't dare to probe her divine sense too far.

Secondly, in order to fight against the water pressure, she will consume a huge amount of spiritual power all the time, which makes her have to rest for half a day every time she walks.

Without a map, she wouldn't have been able to reach the real ocean floor for hundreds of millions of years.

After traveling for a long time, the light appeared in front of Yun Yun's eyes again, and the feeling of not seeing the light for a long time made her dizzy and closed her eyes, even if she was an immortal-level monk, it was unavoidable.

Because, this is too long.

The light came from the magma at the bottom of the sea, and it was as clear as delicious food at the bottom of the sea, reminding Yun Yun that she hadn't eaten in years.

According to the map's guidance, she soon found fairy stone mines on the magma.

This trip seems to be a little too smooth.

After entering the spirit stone mine, the demon sea giants who exuded the power of the immortal level came into Yun Yun's eyes, and they were lying in the fairy spirit stone, as if they were sleeping.

The number of them spread over every inch of the Spirit Stone Mine, making Yun Yun dare not approach those Immortal Spirit Stones at all, let alone find the source spirit of the Immortal Spirit Stone.

After changing a few spirit stone mines, she was a little desperate, because the scene was the same in each spirit stone mine.

In desperation, she planned to try her luck in the small world marked "no entry" on the map, which was between the spirit stone mines, and its entrance was a light curtain in the magma vortex, emitting brilliant light.

Through the light curtain, Yun Yun came to an incredibly empty hall with a high ceiling.

"Detect the inferior half-blood of the Immortal Clan, start the mortal trial!First test, strength!" Suddenly, an emotionless voice rang out.

"What?" After Yun Yun was stunned for a moment, ten Immortal Venerable-level Demon Sea Giants suddenly appeared around out of thin air and surrounded her.

In the midst of danger, she hurriedly retreated to the brilliant light curtain behind her, but unfortunately she couldn't pass through and was blocked.

Immediately after the ten punches bombarded, she had no way to dodge at all, so she could only swing out layers of silk silk to resist.

But how could these silk silks stop those fists, they all collapsed into powder at the touch of a button.

Forced to helplessly, Yun Yun had to fight against these fists that were enough to destroy the Divine Spirit Realm in an instant with her bare hands, but fortunately, although the outer body of the Realm Soul did not have any traces of Gong Shuyi, it retained the strength she had strengthened, unlike the Ninety-Nine Chaos Spirit Branch Cultivation Method, which was directly beaten back to its original form.

Otherwise, this wave of attacks alone would be able to annihilate Yun Yun.

However, each of these punches still caused her to be seriously injured, and it was only by the will of eternal life that she was able to hold on.

"Hey, I came in by accident, can I give up the trial?" said Yun Yun, who sensed that her spiritual power was about to be overdrawn.

It's a pity that there is no voice to respond to her.

"Damn! really made me muddy?" Yun Yun, who was forced to be anxious, said as she condensed hundreds of Yuan Silence attached to the hairpin, and pierced each Demon Sea Giant separately.

During the fluctuation and spread of the source silence, Yun Yun took a pill and recovered some spiritual power, and isolated herself from here with rules.

But under the impact of absolute power, the rules will also be broken, and when Yun Yun is about to be annihilated, the fluctuation of the source suddenly disappears.

"Pass the first trial and get a perfect score of 10. Second Trial, Erudite!" The ruthless voice sounded again, and it seemed that it should be the owner of this voice who suppressed Yuan Li, because the ten demon sea giants were annihilated before Yun Yun.

At the same time, a spirit plant full of immortal aura and a spirit iron that shimmered with extraordinary light appeared in front of Yun Yun.

Behind the spirit plant, there was also a small square with a groove the size of an elixir.

After the spirit iron, there was also a block floating, but it had no grooves.

After some observation, Yun Yun found that these spirit plants were the recipe of a seventh-order immortal elixir, and the spirit iron was enough to refine a top-grade immortal spirit weapon.
