Du Fan took out a jade slip, which recorded a killing technique called "Extremely Cold Ice Domain".

"Extreme Cold Ice Domain" comes from the Northern Underworld family, and "Extreme Fantasy Ice Body" and another mysterious technique, listed as one of the three secret techniques of the Northern Underworld, when Du Fan fled from the extreme north, he learned from the family's peerless Tianjiao soul light ball, and was later imprinted in the blank jade slip, because of the perennial travel, plus the extremely complicated relationship of this spell, it has been put on hold, and no cultivation has been started.

"Extremely Cold Ice Domain" is a domain-level supernatural power, which can be regarded as the continuation and sublimation of the formation-type supernatural power, because there is a certain correlation between the two, but in terms of power, one is in the sky and the other is on the ground, and there is no way to compare them together.

In Du Fan's original cognition, there was no domain-level supernatural power in the Blue Star Realm, only formation-type supernatural powers, such as the "Snake Flurry" he cultivated, and the sword mound supernatural power mastered by a Jindan stage elder of the Wentian Sect back then.

The essence of the formation supernatural power lies in the use of magic to build a formation, and then with the help of the momentum of the formation, it can cause an earth-shattering blow far beyond one's own cultivation, so it is not difficult to infer the mystery of the domain-level supernatural power.

Du Fan immediately urged the Extreme Illusion Ice Body, and outside the body, two clones with a whole body crystal like ice appeared, and the three of them exuded divine thoughts at the same time, submerged in the jade slip, and began to comprehend its inner magical powers, with the help of this way, to minimize the time of enlightenment.

The Extreme Fantasy Ice Body already has a miraculous effect on the Enlightenment Exercises, plus it is out of the North Underworld with the Extreme Cold Ice Domain, there must be some kind of connection between the two, and the use of the Extreme Fantasy Ice Body to comprehend the Extreme Cold Ice Domain can achieve twice the result with half the effort.

This time, Du Fan didn't want to pay attention to the division of the first floor, the second floor, the seventh floor, and the eighth layer, he just wanted to complete the cultivation of the "Extremely Cold Ice Domain" in one go, and finish the battle in one battle, he didn't have much time to waste, and time was running out.

A year later, Du Fan finally comprehended the "Extremely Cold Ice Domain" thoroughly, and then fell into cultivation.

Time flies, and another four years have passed in a blink of an eye, and at this time, "Extremely Cold Ice Domain" has been cultivated to its fullest.

Du Fan went out of the customs and traveled around the world, mainly to find out the news, and finally he breathed a sigh of relief, the Dongfang family had not moved, and it seemed that he had not yet learned about the affairs of the Kyushu Continent.

......

After a short time, Du Fan returned to the cellar of the old mansion in Jinling City again, this time he was not practicing exercises, but refining weapons.

When the underground ancient battlefield of the Valley of Hundred Flowers was separated, the Ten Thousand Eyes Gluttony gave Du Fan a jade slip that recorded a variety of thaumaturgy, including the method of unsealing the ghost and the method of entering the water spirit, if these two things were successfully completed, it would be equivalent to two more Yellow Sky Shaped Treasures at once, and with the strong power of the Yellow Sky Shaped Treasure, his combat power would definitely be greatly improved out of thin air.

Compared with the comprehension and cultivation of "Extremely Cold Ice Domain", the refining weapon is undoubtedly much simpler, not to mention that it is just a sacrifice, not a magic weapon created from scratch.

Seven or eight days later, the Ghost Monk was successfully unsealed, and the result met expectations, showing the power that the Yellow Sky Shape Treasure should have.

It took about a lot of time, the Ice Spirit Cold Light Sword was perfect into the spirit, and the result far exceeded expectations, originally thought that according to the secret method of the Ten Thousand Eyes Gluttonous Injection into the Mother of Water Spirits, at most this sword would reach the edge of the lower limit of the Yellow Sky Shaped Treasure, but unexpectedly, the refining process was surprisingly smooth, and in the end, its grade and power had faintly surpassed the Ghost Lord.

Luck is one thing, and the main thing is the Mother of Water Spirits.

Although the Mother of Water Spirit is a lifeless element, it is like a creature that opens the spiritual intelligence, and the IQ is extremely high, so in the process of refining, Du Fan had a whim, with the attitude of trying, and communicated with him with divine thoughts, but he didn't expect it to succeed.

He made a promise to the Mother of Water Spirits that one day, when his cultivation realm far exceeded the scope of the Yellow Heaven Spirit Treasure, he could return his freedom, and he would also send the Ice Spirit Cold Light Sword as a carrier, and help the other party refine this sword, and then use the sword to achieve enlightenment, break through the life level, and finally incarnate into a real creature.

In return, the Mother of Water Spirits was willing to give, took the initiative to stimulate her own potential, and tried her best to cooperate with Du Fan's refining weapon, which made the Ice Spirit Cold Light Sword reach an unexpected height after entering the spirit.

For a Five Elements element, knowing the reason, moving with affection, seducing it to benefit, and finally reaping miraculous effects, such things that make people speechless, I am afraid that Wanyan Gluttony will be dumbfounded when he knows it.

Counting the Separation from the Fire Diagram, now Du Fan already has three Yellow Heaven Grade Heavy Treasures, among which the Separation Fire Diagram is the Innate Spirit Treasure, with the highest power and grade, and the Ghost Monk and the Ice Spirit Cold Light Sword are the acquired treasures, which are relatively secondary.

"I almost forgot, there's one more ......"

Du Fan's eyes flashed, and he thought of a hot potato, the Three Realms Picture Scroll.

Speaking of which, the Three Realms Picture Scroll is the same as the Separation Fire Diagram, it is the same as the Yellow Sky Spirit Treasure, in terms of grade, it is higher than the other two Yellow Sky Shaped Treasures, but it is seriously damaged, and the power has fallen a lot, and then it is the suppression of the three otherworldly murderers, if this hidden danger is not removed, there is always no way to use it with peace of mind.

"Actually, don't worry about anything, two thousand years ago, the Five Ancestors of Ximen held the Three Realms Picture Scroll to suppress the three otherworldly murderers, although they could not be completely wiped out, but it was enough to explain the problem, they should be at the same level between them, these three otherworldly murderers are not life-threatening to me. ”

Du Fan decided to take some risks to enter the Three Realms Picture Scroll, and he would meet the so-called Otherworldly Murderer, firstly, to try to kill these three murderous creatures, to eliminate the aftermath forever, and to make the Three Realms Scroll truly for his own use, and secondly, he had a vague feeling that the other party was likely to be related to lawlessness, as long as it was about lawlessness, he wanted to understand.

But before that, he had to go out to inquire about the news of the Dongfang family again to make sure that he was safe.

......

Half a month later, Du Fan returned from inquiring about the news, but the outside world was still calm, and there was no clue of the advent of the Dongfang family.

Du Fan immediately spread out the Three Realms Picture Scroll, and then stepped into it along a portal.

It was a ghost world, almost filled with darkness, the sky was overcast, the earth was ghostly, and most of the time there was a deathly silence, with the occasional scream or two, eerie and terrifying.

Du Fan's figure flickered, and he quickly came to the end of the ghost world.

He stood in front of a sarcophagus and felt the strength of the creatures within.

After observing for a while, Du Fan suddenly raised his arm, broke up the surrounding prohibitions, and pushed the coffin lid open in the air.

The next moment, the sound of breaking the sky sounded, and two blood-colored cold rays burst out from the sarcophagus, which was the gaze of the murderer of the other world, like a substance, cutting through the void and piercing the sky, extremely terrifying.

"Roar!" Immediately afterward, a dull roar rang out, continuous and deafening, as if the prehistoric beast was awakening.

Without saying a word, Du Fan directly sacrificed the water of the Yellow Spring, turned it into a water curtain, replaced the coffin lid, and sealed it on the sarcophagus.
