Li Dong took out the Thousand Illusion Flowing Cloud Sword, extracted thirty-six Dao patterns from the Dao Seal and began to practice.

The difficulty of refining the sword rune is much greater than that of the rune of the seed recognition, and after Li Dong practiced for an hour, he was stunned to find that there was some black liquid dripping faintly in the Thousand Illusion Flowing Cloud Sword, which was the impurity in the sword? How can this art of sacrificial sword refining runes also have the effect of refining magic weapons? Is it really the three thousand Dao Fa, and the different paths lead to the same end?

The sacrificial refinement continued, and for another hour, a burst of black mist rose from the Thousand Illusion Flowing Cloud Sword, which was the residual essence blood imprint of Yuan Datou, and this hidden danger that Li Dong was helpless was actually easily solved.

Another hour, the Thousand Illusion Flowing Cloud Sword was finally refined, and at this time, the Thousand Illusion Flowing Cloud Sword had been transformed into a rune the size of a soybean, which was sucked into the Dao Seal and cultivated in the Purple Mansion.

The sacrificial refining technique of the sword rune is really magical, not only can it wash away impurities and improve the quality of the flying sword, but it can also erase the breath imprint of the flying sword that does not belong to the owner of the flying sword, making the flying sword more pure, and it can be included in the purple mansion like a magic weapon. There are too many ancient secret methods lost in today's cultivation realm, and the level of cultivation is far lower than that of the ancient era.

When Li Dong stood up, the water puppet standing on the side immediately spoke: "Trial disciple, do you want to continue to challenge the third level?" ”

"Yes, the disciple wants to challenge the star difficulty"

The water golem flicked its fingers, and the water elf reappeared.

"You are only allowed to use water-based spells, and if you defeat the water elves within ten breaths, you can pass the level and get rewards."

Li Dong didn't dare to delay at all, he quickly pinched the seal with both hands, and released six spells in a row, including four "turbid waves", one "boundless rain", one "water cloud sky", five attack spells, and one defensive spell.

The Dao Seal in Li Dongzi's Mansion roared, and five soybean seed-sized runes flew out of his body, disappeared in a flash, and disappeared into the five attack spells.

In an instant, the valley shook for a while, the wind suddenly rose, and the water dragon transformed by the four spells roared fiercely and rushed towards the water elf, and above the head of the water elf, there was a boundless rain pouring down like a popping cloth, this boundless rain was not ordinary rain, but the rotten water turned by mana, everything was rotten, and nothing was indissolved.

Heaven and earth are discolored! In the valley at this moment, the wind was fierce, the rain was pouring, the waves were raging, and the sound was extremely terrifying.

Li Dong didn't expect that using the seed recognition rune to control the spell would actually have such a big increase in the power of the spell, almost similar to the power after condensing the method rune, and the knowledge rune was still so useful?

The water elves of star difficulty can only cast two spells at the same time, and the water elf's "rainy sky" cannot break through Li Dong's "water cloud sky" defense at all, and Li Dong's five powerful spells The water elf can't resist it at all, and after only three breaths, the water elf was torn into pieces by the four water dragons, turned into a drop of water again, and was retracted by the water puppet and disappeared.

"Pass the third level of star difficulty, this real water is a reward for you to clear the level, please collect it."

The water puppet opened its mouth and spit out a cyan bamboo bottle, Li Dong hurriedly collected the bamboo bottle, uncorked it and saw that there were drops of blue viscous liquid inside, thirty-six drops each.

A rich and pure water system vitality rushed to his face, just smelling the smell, it made Li Dong's water system mana in his body be strongly attracted, and the violent fluctuations boiled, Li Dong forcibly suppressed the restlessness of the water system mana, with his temporary cultivation, there was no way to refine the true water.

This is the real water under the Xuan Rank, and the real water is heavy.

Chongxuan real water is also weighed water, and its characteristic is one word: heavy.

A drop of the heavy Xuanzhen water of the lower grade of the Xuan Rank weighs 10,000 catties, which is a common spiritual material for refining magic weapons, the famous innate spiritual treasure in ancient times, Feilai Peak, and the Soul Suppression Tower have all used the heavy Xuan Zhen water, and it is a large number of heavy Xuan Zhen water of the upper grade of the Heavenly Ladder, and the weight of a drop of the heavy Xuan True Water of the upper grade of the Heavenly Ladder is not less than the weight of a mountain.

Therefore, the weight of these spiritual treasures has reached an incredible level, so they can make a name for themselves in ancient times.

As soon as the Heaven Turning Seal came out, the power was that the immortals had to retreat, and the Divine Realm monks who died under the Heaven Turning Seal did not know how many.

Of course, Chongxuan True Water can not only be used to refine magic weapons, but can also be refined and absorbed by monks, but at least it can only be refined and absorbed by Dao cultivation.

Next, Li Dong successively challenged the month-level and day-level difficulties, and with the same fierce spell attacks, he successfully passed the level, and harvested a copy of the Xuan-level middle-grade and the Xuan-level high-grade Heavy Xuanzhen Water.

"The third level of the trial has been passed, do you want to continue to challenge the fourth level?"

"Yes, the disciple wants to challenge the fourth level"

Standing on the teleportation array, the water puppet activated the teleportation array, and the scenery in front of Li Dong's eyes changed, he appeared in a desolate desert, and as far as the eye could see, except for a towering seven-story tower, there was boundless yellow sand.

The tall tower made of huge stones looks a little old, standing alone in the desert covered with yellow sand, looking particularly desolate, and there are five vigorous and powerful characters on the tower: Cloud Sea Trial Tower.

Li Dong released his divine sense to search around, but he didn't find the stone tablet, nor did he find the puppet guarding the pass, this fourth level seems to be a little different from the first three levels.

The Tower of the Sea of Clouds? Could it be that this fourth level is to climb the tower? How many floors do you have to climb to get through? Why don't you give a hint?

Li Dong hesitated for a moment, there should not be any danger in the tower, after all, this trial tower is used by the Yunhai Sect to train disciples, and it will definitely not endanger the lives of the disciples under him, so go into the tower and take a look.

Walking up the stone steps, in front of the tower gate on the first floor, Li Dong tried to push the boulder gate.

"Boom" A noisy sound sounded, and the boulder gate was easily pushed open by Li Dong.

Li Dong raised his feet and entered the tower, just took two steps, the stone door behind him was automatically closed, the light in the tower suddenly dimmed, not far away there was a huge white jade tablet exuding dazzling white light, faintly you can see that there are many dense handwriting on the jade tablet.

Is this the boundary monument of the fourth level? How did it become a jade stele, the first three levels are all stone tablets, and this jade tablet is also too big, more than a hundred times larger than the stone tablets of the first three levels.

After Li Dong got closer, he found that this huge jade tablet was not a boundary tablet, but a inheritance jade tablet that recorded the list of true disciples and core disciples of the Yunhai Sect.

The jade tablet is densely filled with names, starting from the first row, there are about 1,300 people in the true biography column, and at least more than 100,000 names in the core column.

Obviously, the identity of the true disciple is higher than that of the core disciple, but the strange thing is that the names of all the true disciples are dark, but among the core disciples, there are more than 20 people whose names are bright, and among the more than 20 names that are lit, the first name is Li Qingchen, ranking in the middle of the names of more than 100,000 core disciples, while the remaining 20 or so names are in the back position of the core disciples.

Of the more than 100,000 names on the huge jade tablet, only more than 20 names are lit, what does this mean?

At that moment, a voice suddenly appeared.

"Trial disciple, please engrave your name with essence blood on the Inheritance Soul Tablet."

Li Dong was taken aback, who is talking here? His divine sense did not find that there were people in the tower, and the sound did not resemble that of a puppet, because the sound made by the puppet was relatively low, like a mechanical synthesis sound of a computer, and it was very recognizable.

"Senior, please show up." Li Dong released his divine sense to search around, but found nothing.

At this moment, a bare-bottomed little boy suddenly appeared in the Inheritance Soul Monument, looking like he was two or three years old, but his body was still a little illusory, looming, and it was obvious that the transformation had not yet been completed.

"Boy, what are you calling me for?" The little boy stood in the air in the air, just at the level of Li Dong.

"Are you the instrument spirit of the Soul Monument?" Because of the existence of the little cutie, Li Dong guessed the true identity of the little boy in front of him for the first time, what level of spiritual treasure is this inheritance soul tablet? Although he has spiritual intelligence, his transformation is not complete, and it is definitely not as good as the Heavenly Ten Thousand Defining Astrolabe.

"Yes, no one has come to the Trial Tower for a long time, and since you have passed the first three levels, you are qualified to become the core disciple of the Yunhai Sect, and engrave your name with essence blood on the inheritance soul tablet."

"The Yunhai Sect has long since perished, everyone is dead, how can there be any Yunhai Sect." Li Dongcai didn't want to be the core disciple of the Yunhai Sect, he was the only one in the sect who had a fart, and it would make people laugh when he said it.

"Who said that the Yunhai Sect perished? Don't you see that there are still twenty-five names on this soul tablet that are lit? ”

"Does the name indicate that the person is still alive?" Li Dong asked strangely, "It's been more than 30 million years, how can anyone still be alive?" Could it be that these people have become immortals? ”

"How can it be so easy to become an immortal, except for Li Qingchen, who may have become an immortal, the rest are all Yunhai Sect that has only entered in the last few thousand years, and now they should all be cultivators of the Divine Realm, at least they can live for tens of thousands of years."

Li Dong roughly understood that the order of the names on this inheritance soul tablet was sorted by the time of entry, Li Qingchen's name was in the middle of the stone tablet, and he should be a monk at the end of the ancient era, but since he could cultivate to become an immortal, he should be peerless, why is such a genius just a core disciple? So what kind of person is qualified to become a true disciple?

"Why is Li Qingchen just a core disciple? As the only disciple in the history of the Yunhai Sect who has ascended to immortality, how can he be qualified to become a true disciple, right? Li Dong asked the doubts in his heart.

"Who told you that Li Qingchen is the only disciple in the history of the Yunhai Sect who has ascended to immortality?"

"Isn't this clear? The entire sect has already died, leaving Li Qingchen alone, if he becomes an immortal, how can he die? "Li Dong is not stupid, how can he not understand such an obvious truth.

"Boy, who told you that immortals don't die? Do you know how long the history of the Yunhai Sect is? It has been more than 100 million years since the flood era, and there are at least more than 1,000 immortals in Yunhai Sect, but Li Qingchen is the only one who is alive, and only the true immortal can really live forever. ”

Li Dong was stunned, immortals will also die? True Immortal Realm Li Dong knew that this was the ultimate peak of cultivation, the fifth realm of the Five Realms of Immortals.
