The only divine flower must gather all the petals before it can be used, otherwise, it will even poison the Demon Emperor. This is also the reason why the White Heart King and the Northern Demon Emperor did not use the One Divine Flower.

Yang Fan swallowed the only divine flower in one gulp.

In an instant, various visions of the birth and destruction of the universe suddenly appeared in Yang Fan's eyes, and a mysterious but extremely pure power submerged into his [Evolution] skill spell seal.

Yang Fan's body instantly turned into an incomparably terrifying black hole, frantically devouring countless supreme evolution points.

Bursts of incomparably bright divine light appeared in Yang Fan's body, making his aura more and more terrifying.

A year flies.

In the Yanhuang Cave Mansion, Yang Fan slowly opened his eyes.

"Unique quality [Evolution] skill, the current half-step unique evolution skill points are 2.5!"

"The [Evolution] skill has finally advanced to the only quality. As long as the half-step unique evolution skill points reach 10 points, I can advance to become a powerhouse of the only realm!"

"How many half-step unique evolution skill points can all my current resources be converted into?"

Yang Fan's mind moved, and he activated the insight skill.

"All current resources can be converted into 5 points and a half step of unique evolution skill points!"

A line of information emerges.

As long as Yang Fan refines all the countless heavenly and earthly treasures he obtained from the Northern Demon Emperor's resource treasury, and transforms them into supreme evolution points, and then converts them, he can obtain 2.5 points and a half step unique evolution points.

Yang Fan frowned slightly: "If you give me a slow accumulation, as long as it takes about 100 million years, I can advance to the only realm powerhouse!"

If he had a choice, Yang Fan, who had already advanced to the Demon Emperor, would be more willing to take it step by step and honestly find a way to accumulate it for 100 million years. However, the destruction of the universe is imminent, and he can only find another way.

"Killing a Demon Emperor can earn about 3.5 half-step unique evolution points. As long as I kill the other three demon emperors, I should be able to advance to the One Realm!"

"But those three Demon Emperors will definitely not obediently stay where they are and wait for me to kill! And if they cower in the Demon Emperor Palace, there is nothing I can do!"

Yang Fan calmly analyzed, he was able to capture the Northern Demon Emperor Palace so easily and easily, it was because the Northern Demon Emperor came out of his lair to hunt him down.

If the Northern Demon Emperor retreats into his lair, Yang Fan and his party will definitely not be so easy to storm the Northern Demon Emperor Palace. At the very least, it will be guarded by the Northern Demon Emperor for a few days.

A few days is enough time for the allies of the Northern Demon Emperor to come to support!

The Northern Demon Emperor was able to stand out in the era of the Demon Emperor War, and naturally he also had allies. Otherwise, he would have been killed by the other Demon Emperors a long time ago.

Of course, after the Northern Demon Emperor occupied the Northern Demon Realm, he not only divided a large area of the Demon Domain to his allies, but also formed a community of interests with his allies to fight against the other three Demon Emperors.

"It's better to use the existing resources to strengthen our strength!"

Yang Fan weighed it again and again, but still gave up converting all the resources into half-step unique evolution points.

In the battle to besiege and kill the Northern Demon Emperor, the reason why the three of them were hit hard was because they did not have the imperial weapon.

If the three of them have an imperial weapon, their combat power can definitely soar again, and the battle to besiege and kill the Northern Demon Emperor will be easier and more certain.

Yang Fan came to the Sun God Furnace and began to use materials to forge imperial weapons for the three of the Golden-Winged Dapeng.

The Northern Demon Emperor occupies the Northern Demon Realm, and there is no shortage of all kinds of heavenly and earthly treasures. The reason why he only has one imperial weapon is because a demon emperor can basically only control one imperial weapon perfectly. No matter how many emperors there are, for them, it is a burden that is difficult to use perfectly.

The Northern Demon Emperor only refined two [Imperial Bone Demon Blades], one was captured by Yang Fan after his fall, and the other was used as a backup in his secret vault, which also fell into Yang Fan's hands.

Three months went by in a flash.

"It's finally refined!"

The corners of Yang Fan's mouth raised slightly, looking at the three imperial weapons suspended in front of him, his eyes showed a hint of satisfaction.

The three imperial artifacts are the [Space Blade] that holds the power of space, the [Spirit King City] that holds the power of the spirit body, and the [Heart of Ten Thousand Worms] that holds the power of insects.

"It's all yours!"

Yang Fan waved his hand, and the three imperial weapons immediately flew into the hands of the golden-winged Dapeng, Xiao Hei, and the black scorpion.

"Thank you, master!"

The three black scorpions got their own imperial weapons, and they couldn't put it down, full of joy. After they obtained the imperial weapon, they became the strongest among the demon emperors in one fell swoop.

"It's time to find the next prey!"

A cold glint flashed in Yang Fan's eyes, his figure flickered, and he disappeared in a flash.

The White Flame Demon Palace in the territory of the Southern Demon Emperor.

"That human demon emperor always gives me an ominous premonition. “

The White Flame Demon Sea sat in a pavilion with a gloomy face. He has always regarded the Terrans as ants and has not taken them very seriously. Now a human demon emperor was born, which reminded him of the palace master of the Black Moon Palace, who hated him to the bone.

"You are the White Flame Demon Sea?"

With a trace of ripples, Yang Fan immediately appeared in front of the White Flame Demon Sea and said lightly.

Bai Yan Demon Sea's heart sank slightly, and he said respectfully: "I've seen the Desolate Flame Demon Emperor!!!

With a flash of sword, the White Flame Demon Sea immediately split its body, and its eyes flashed with disbelief, scattered on the ground.

A demonic light flew towards Yang Fan, but it was directly shattered by his casual blow.

Inside the Southern Demon Emperor Palace.

"He's here!!Desolate Flame Demon Emperor, his target this time is me!!"

The Southern Demon Emperor opened his eyes suddenly, and a trace of killing intent flashed in his eyes and said slowly.

"Let's join forces to kill him?"

A Black Yuan Demon Emperor who was shrouded in a layer of black cloth, making it impossible to see his true face clearly, said slowly.

The Black Yuan Demon Emperor is an ally of the Southern Demon Emperor. The Northern Demon Emperor has fallen, and the Demon World is in chaos. The Southern Demon Emperor naturally wanted to invite allies so as not to be killed himself.

"No! The strength of the Northern Demon Emperor is very strong!!He has fallen! It means that the Desolate Flame Demon Emperor is only afraid of having more than three Demon Emperors holding imperial weapons!!

The Southern Demon Emperor frowned slightly, took out a black jade talisman and crushed it directly.

Two black mist were suspended in the void at once.

"Southern Demon Emperor, what are you looking for us?"

From the black mist, a cold and indifferent voice came out.

The Southern Demon Emperor said: "The Western Demon Emperor, the Eastern Demon Emperor, and the Desolate Flame Demon Lord have appeared! He is in my sphere of influence!
