The underground palace is located in the deepest part of the valley. Unlike the heavenly palace, which is shrouded in clouds and mist and full of fairy spirit, there is a strong evil aura surrounding this underground palace. This evil aura is so strong that Lin Yu can't help but frown.
.
Even a trace of such strong evil spirit is enough to cause the death of warriors below the sixth level of the Emperor. Even ordinary sixth-level emperor warriors would find it difficult to withstand the invasion of this evil energy.
That is to say, Lin Yu and everyone behind him are not ordinary warriors, so they are not affected by this evil spirit.
"Lin Yu, before you start to break through, I have to remind you that this underground palace is not as simple as the heavenly palace."
Seeing that Lin Yu was about to enter the underground palace, Yang Yun took a step forward and said: "In the heavenly palace, all the opponents you face are imaginary and virtual. No matter what, they will not really kill you, but
This underground palace is different!"
"This underground palace was originally a place of absolute evil, filled with terrifying evil energy. Even the true gods could not easily enter. Later, after the transformation and guidance of the palace master, the underground palace was formed today!"
"In the underground palace, all creatures are formed by the condensation and transformation of evil spirits. We call these creatures evil spirits!"
"Because they are transformed from evil spirits, these evil spirits are extremely cruel and cunning, and have a bloodthirsty instinct. They will continue to fight even among themselves, and if someone from the outside breaks in, they will be even more violent.
They're crazy about it!"
"Although in the underground palace, there are restrictions left by the master of the palace, you only need to shout to leave and you will be teleported out, but many times, those demons will make you not even have the chance to shout to leave!"
"Every year, many warriors die in this underground palace. Lin Yu, although you have broken through the ninth floor of the heavenly palace, you still have to be more careful when entering this underground palace!"
"I see."
Hearing Yang Yun's words, Lin Yu's face could not help but tremble. He bowed his hands to Yang Yun and said, "Brother Yang, thank you for reminding me."
The previous token only stated that the underground palace is a place to test survival ability, but it was not as detailed as what Yang Yun said. Yang Yun's reminder was undoubtedly extremely important to Lin Yu.
The next moment, Lin Yu looked solemn and stepped into the underground palace.
Whoosh!
His figure flashed, and he suddenly appeared in a vast and boundless dark world. There was no light in this world, and it was extremely cold and evil.
Wisps of extremely cold black smoke are floating everywhere in this world, and among them are countless sharp and weird laughters. That kind of laughter has a kind of gloominess that penetrates into the bone marrow, making people shudder.
If you take a closer look, you will see that it is not black smoke at all, but countless creatures shrouded in black mist. Their bodies are translucent, semi-substantial, and full of strong evil spirits. They are countless evil spirits!
"Jiejie, another human is coming!"
"Eat him, eat him! This is a great tonic, eat him!"
Sensing Lin Yu's arrival, the countless black smoke suddenly boiled, and countless demons, wrapped in the cold black smoke, came directly towards Lin Yu!
"So many demons!"
Lin Yu's expression changed slightly. The number of demons attacking him around here alone had exceeded one hundred thousand. If Yang Yun hadn't reminded him before and was caught off guard, he would have suffered a big loss!
"Great Chaos Thunder Sword!"
Quickly regaining his composure, he swung his sword without even thinking about it. The sharp sword energy exploded, bursting out with infinite thunder power, pouring towards the surrounding demons!
Thunder and lightning are the most domineering power, specialized in restraining all kinds of evil spirits, and evil spirits are also considered a kind of evil spirits. When they encounter Lin Yu's sword, they are naturally like encountering a natural enemy!
"Ahhh!"
"This human being has actually mastered the power of thunder and lightning! Retreat, let's retreat!"
Countless demons screamed miserably, and in just a few breaths, tens of thousands of demons were directly killed by Lin Yu, while more demons dispersed frantically, directly choosing
Run away!
"snort!"
Seeing this, Lin Yu snorted coldly, but did not catch up.
After all, he was new here and didn't know much about this world. If these demons led him into a trap, he would be the one in danger.
"Um?"
Just as he was about to leave, his eyes suddenly focused, and he found that the corpses of the demons he killed had turned into a faint black mist. The black mist quickly condensed, and soon turned into a mung bean-sized corpse.
Black beads.
"This is?"
After feeling it for a while, Lin Yu couldn't help but raise his eyebrows.
These black beads contained an extremely pure evil spirit. Although the quantity was small, its purity was the first time Lin Yu had seen it.
This pure evil spirit has a great effect whether it is converted into true energy to absorb, or it is refined into weapons to enhance the power of weapons.
It is a pity that the evil spirit contained in this black pillar is too little. This little evil spirit has no effect on Lin Yu at all.
However, this is not surprising. After all, the evil spirits Lin Yu killed were almost all under the Emperor's realm. It was already very good to be able to generate these evil spirits.
"This underground palace is quite good. In addition to the test, you can also get some additional gains."
Lin Yu nodded and continued to act.
Next, he did not go on a killing spree in the first level. After all, the evil demons in this level were too weak. Even if they were all killed, not many evil energy beads would be produced.
If you really want to get a rich enough harvest, you must enter deeper layers and kill more powerful demons!
A few hours later, Lin Yu finally found the passage to the second floor, and without any hesitation, he entered directly.
On the second level, the number and strength of evil demons have been significantly improved compared to the first level, and a small number of evil demons have even reached the emperor-level existence.
Of course, no matter how large the number of evil demons of this level were, they could not pose any threat to Lin Yu. They easily killed a large number of evil demons, and Lin Yu found a passage to the third floor.
And in this third level, the strength of these evil demons has obviously made a qualitative leap. Almost all evil demons have reached the emperor realm!
Some of these demons no longer can only be killed by instinct, but have developed a certain degree of wisdom and know how to use the evil energy to condense into weapons. Even a very small number of them have even created quite powerful moves.
.Under the joint attack of hundreds of thousands of emperor-level demons, Lin Yu's threat immediately increased greatly!
