"Very good, there are only 200 million energy points left until the ninth evolution!"

Su Yehan released his skills while instructing the system to open the attribute and look at the energy value.

At this time, there were only about five or six hundred resentful skeletons left in the canyon.

"Nether Thunder!"

"Yellow Springs Corpse Qi!"

"Nether Flame!"

Su Yehan's heart moved, and three powerful skills were released in succession, heading towards the remaining resentful spirit skeletons.

"Boom!"

"Boom!"

"Boom!"

Flames, thunder, and corpse qi fell on the group of resentful skeletons, erupting into bursts of roar.

"Ding! Congratulations to the host for killing the Wraith Skeleton and gaining 200,000 energy points!"

"Ding! Congratulations to the host for killing the Wraithing Skeleton and gaining 190,000 energy points!"

"Ding! Congratulations to the host for killing the Wraith Skeleton and gaining 170,000 energy points!"

With the death of the resentful spirit skeleton, the prompts of the system kept ringing in Su Yehan's mind.

A few minutes later, all the remaining resentful spirit skeletons had turned into broken bones, and at this time, Su Yehan's energy value had reached 4.9 billion points, which was only 100 million points away from the five billion required for evolution.

"There are still 100 million points left, you can evolve again, and you can get it by killing a monster!"

Su Yehan's huge eyes swept over the canyon with mountains of bones, and thinking in his heart, the wolf body was about to rise into the air.

But at this moment!

"Boom!"

"Boom!"

The huge canyon suddenly shook the mountain as if it were the end of the world.

Seeing this, Su Yehan was shocked and hurriedly flew into the air.

Su Yehan naturally understood that there were resentful spirit skeletons in this canyon, and maybe there would be some secrets hidden, but just now, his perception ability spread out, and he didn't find any abnormalities.

Unexpectedly, just as he was about to leave, a sudden change occurred.

"Boom!"

"Boom!"

The huge canyon was constantly shaking, and by this time, a large number of cracks had appeared in the ground and were continuing to expand.

"What secrets are hidden in this canyon, could it be that there are powerful monsters underground?" Su Yehan thought to himself as he looked at the cracks on the canyon floor that were getting bigger and bigger.

At the same time, he was also ready to flee at any time, after all, if there was really a powerful monster hidden underground, Su Yehan would not necessarily be an opponent.

At the same time that Su Yehan was thinking like this, in the canyon, in a crack in the ground that was tens of meters long, a sky-high purple light suddenly bloomed.

"Buzz!"

At the same time as the purple rays of the sky emanated, a strange sound came out of the cracks in the ground.

"What is this purple light?" Su Yehan was shocked in his heart.

But the next moment, a huge purple flame suddenly flew out of the crack.

"The weird sound just now is from this purple flame, and the monster in the ground is this purple flame!"

Su Yehan looked at the purple flames in the canyon that were five or six hundred meters in size, and he was shocked.

Before this, even if he met King Kong, Muto, and Ratton, he was not so surprised.

Although these are monsters in the movie, they are also strange life forms.

However, what appeared in front of him now was a huge purple flame.

"Roar!"

The next moment, among the purple flames, there was an angry roar, and then, a purple light swept through the entire canyon with the purple flames as the center.

The strange thing was that where the purple light passed, the skeleton bones of the resentful spirits that had been killed before actually flew towards the purple flames quickly.

When Su Yehan saw this scene, his heart was even more shocked, and then, a thought came to his mind.

"Is it because of this purple flame that these skeletons are resurrected and become resentful skeletons?"

The more Su Yehan thought about it, the more he felt that it was very possible, and this purple flame might be the biggest secret in this canyon.

A large number of bone fragments gathered towards the purple flames, and in just a few breaths, the bone fragments had already covered the purple flames.

And these broken bones, under the control of the purple flame, with the purple flame as the center, formed a skeleton giant with a size of a thousand meters.

This scene is similar to the huge skeleton monster in the legend of Shushan.

The Skeleton Giant, or the Wraithing Sovereign, is a thousand meters tall, and his whole body is flowing with purple light,

One held a purple bone sword, the other held a purple bone shield, and in his eyes, purple flames beat wildly.

"Demon clan, damn it!"

But the next moment, Su Yehan was really shocked.

Because of the resentful spirit monarch, he actually spat out people's words.

Don't ask why Su Yehan understands it, because the whole universe speaks Chinese.

"How is this possible!" Su Yehan was extremely frightened, a purple flame could actually speak.

"Also, it calls me a demon clan, could it be that this purple flame has seen a real demon clan?"

The real demon clan will naturally not be a giant beast such as the prehistoric emperor python, the King Kong King, and the Titan giant crocodile.

It's not Muto, Ghidorah's kind of movie monster.

Too much incomprehension appeared in Su Yehan's heart, but at this time, he couldn't be allowed to think about it anymore, because the Resentful Spirit Monarch had already killed him.

"Demon clan, all damn it!"

The Wraithing Monarch roared angrily and took the lead.

"Lao Tzu doesn't care who you are, as long as you are killed, Lao Tzu can evolve again, and when the time comes, he can naturally go to the depths of Skull Island and uncover the secrets of Skull Island!"

Su Yehan's heart was infinitely murderous, and he was not afraid of the resentful spirit monarch at all.

"Nether Flame!"

Su Yehan let out a wolf howl, and his huge mouth opened, spitting out a cloud of dark and inky poisonous flames.

"Whew!"

Nether Flame burst through the sky and slammed it towards the Wraithful Sovereign.

Seeing this, the Resentful Spirit Monarch was not afraid at all, and the bone sword glowing with purple light in his hand rose and fell, directly slashing at the Netherworld Poison Flame.

With a bang, the Nether Poison Flame scattered under the slash of the bone sword.

"The strength of this resentful spirit monarch is even stronger than the prehistoric emperor python, Ghidorah and so on!"

After Su Yehan watched the Resentful Spirit Monarch defeat the Nether Poison Flame with a single sword, he had a judgment on the strength of the other party.

"Die!"

The Wraithing Spirit Monarch let out a hoarse sound, and a sword slashed towards Su Yehan.

The purple bone sword made a burst of sound from breaking the sky, and wherever it passed, it seemed that even the space had been cut into a slight crack.

Even if Su Yehan was conceited, he didn't dare to be careless at this time, and with a thought, the wolf's body turned into a green mang, and he quickly retreated, dodging the attack of the purple bone sword.

At the same time, the killing eye between Su Yehan's eyebrows, the dark matter in it suddenly turned rapidly, and the next moment, a dark ghostly thunder as black as ink emitted, roaring towards the resentful spirit monarch.

"Demon clan, you will die!"

The Wraith Monarch roared, his shield raised, fending off the Nether Thunder.

"Boom!"

Nether thunder slammed into the shield, erupting with a roar.

It is worthy of the Wraith Sovereign, even if it is a shield composed of broken bones of the Wraith Spirit, but with the blessing of purple flames, it can withstand the terrifying Netherworld Thunder.
