It turned out that after the black impermanence was driven into the deep mountains and bad waters, he began to practice diligently, dreaming of finding Lin Wang for revenge one day, perhaps it was good luck, and he found a hidden cave in the deep mountains and bad waters, the cave was in ancient times, thinking that the powerful people of the underworld were retreating and cultivating places, and then this powerful man died for unknown reasons, and the cave was deserted, but he did not expect to be found by the black impermanence, and the black impermanence found this black yin knife in the cave, the black yin knife is about two zhang long, and it is a very powerful underworld immortal treasure! Even in the immortal realm, the Black Yin Knife is also very famous! After tens of thousands of years of cultivation, he can finally master the Black Yin Knife proficiently.

After listening to Hei Wuchang's words, Lin Wang smiled: "Hei Wuchang, no wonder you dare to provoke me? It turns out that you have found a powerful immortal treasure? I want to see how powerful the Black Yin Knife in your hand is! Is it really as powerful as the legend!" Don't look at what Lin Wang said lightly, in fact, he is still a little worried in his heart, for the Black Yin Knife, Lin Wang has also heard that the Black Yin Knife is an eight-grade immortal weapon, and the power is absolutely extraordinary, a long time ago, the legend of the Black Yin Knife was spread in the underworld, and Lin Wang also worked hard to find it, but unfortunately he found nothing in the end, I really didn't expect that in the end, the Black Yin Knife actually fell into the hands of Black Impermanence, it seems that today's battle is a bit dangerous, Lin Wang took advantage of the negligence of Black Impermanence's defense, pulled out a sword and slashed towards Black Impermanence.

Hei Wuchang saw Lin Wang attacking him, and immediately sneered: "It's really looking for death!" Hei Wuchang shook the black yin knife in his hand, and he rushed towards Lin Wang, and in the blink of an eye, black impermanence came to Lin Wang's body, raised the black yin knife and stabbed Lin Wang's chest, the black yin knife slashed through the sky, making a sound of "zizi ......zizi", which was enough to see that the power of the black yin knife was great.

Seeing this, Lin Wang was secretly surprised in his heart, when did the speed of black impermanence be so fast, but he was surprised, Lin Wang still raised his sword to resist, only to see Lin Wang's wrist shock, and the sword leaned up, blocking the black yin knife stabbed by black impermanence, "Puff ......" With a muffled sound, the sword in Lin Wang's hand sank suddenly, and then Lin Wang was shocked out by a huge force, although he blocked the black and impermanent black yin knife, but Lin Wang still suffered a dark loss, only to see a deep crack on the blade of the sword, which was slashed by the black yin knife, so it can be seen how sharp the black and impermanent black yin knife is.

While Lin Wang felt sorry for his sword being damaged, he also admired the sharpness of the Black Yin Knife, which was worthy of being an eight-grade immortal weapon, and its power was powerful.

Hei Wuchang Lin Wang suffered a secret loss in his own hands, and sneered: "Lin Wang, the sword in your hand is too bad, how can there be such a big crack in just one move? Haha...... "Hei Wuchang is really happy, how many years have passed, and he can finally clean up Lin Wang openly, it's really relieving."

Lin Wang frowned, he knew that the Black Yin Sword was powerful, but he didn't expect it to be so powerful, the sword in his hand was called Bailu Sword, it was a seventh-grade immortal weapon, and he had been following him for many years, even if he was not the opponent of the eight-grade immortal weapon, but he wouldn't be able to catch a single blow, right? Lin Wang groaned for a while, put away the Bailu Sword, and then sacrificed a seal, the whole body of the seal was extremely black, and there were many ghost heads carved on it, and the aura emitted was also very cold and huge.

The black and uncommon Lin Wang sacrificed a seal, and his pupils suddenly shrank: "Hades seal, you actually sacrificed the Hades seal!" The Hades seal is the treasure of the underworld, it is the gift of the immortal emperor, it is a real eight-grade immortal weapon, and it is also a super eight-grade immortal weapon, which is compared with the nine-grade immortal weapon, the Hades seal is a symbol of the underworld, very precious, so usually Lin Wang is a treasure, and he is reluctant to take it out against the enemy.

"Black impermanence, you should know how powerful the Hades Seal is, your Black Yin Knife will definitely not be able to resist the Hades Seal, now, if you are captured, I can also consider sparing your life!"

"Hahaha...... What a big joke, Lin Wang, you let me be caught, dream, even if you have the Hades Seal in your hand, I am still not afraid of you, the Black Yin Knife has reached the top of the Eight Rank Immortal Weapon after my cultivation over the years, and it is definitely more than enough to deal with your Hades Seal!"

"Don't be ashamed, I'll let you see the power of the Hades Seal today!" Lin Wang snorted coldly, shook his hand, and the Hades Seal flew into the air, dripping and turning, the volume increased more than ten times, and it became a big seal about a few feet high.

Hei Wuchang Lin Wang activated the Hades Seal, his face sank, and he said loudly: "Lin Wang, I swear that I will definitely break you into ten thousand pieces!!" Hei Wuchang held the Black Yin Knife tightly, and shouted loudly in his mouth: "Black Yin Knife, rush me !!"

"Huhuhu......" A gust of wind suddenly blew around.

Hei Wuchang let out a loud shout, and slowly stabbed out, and a dazzling black light suddenly shot out from the tip of the Black Yin Knife, whistling towards Lin Wang.

Lin Wang's face changed, and he hurriedly flashed aside.

The black light hit a boulder behind Lin Wang, and with a loud bang, the boulder instantly turned into a pile of powder......

Lin Wang was secretly surprised in his heart, fortunately he dodged quickly, otherwise, he would definitely be hit hard, this black yin knife really deserved its reputation, Lin Wang waved his big hand, and countless dazzling rays of light shot out from the seal of the king of Hades, these rays of light dispersed, and quickly shot towards the black impermanence.

"Hmph!" Hei Wuchang snorted coldly: "Black Yin Knife, block it for me!!" A layer of black mist suddenly appeared around Hei Wuchang's body, and ......countless lights instantly hit the black mist, without any sound, and those rays disappeared in an instant.

"Hiss......" Lin Wang gasped: "What's going on?Why did the ten thousand rays of light disappear like this?" "Since the ten thousand rays of light can't work!, then add some more light!" Lin Wang's hands rubbed together violently, and the Hades seal suddenly emitted a fierce light, this time the light emitted by the Hades seal was even more dazzling and dense than the last time...... At first glance, there are tens of thousands of rays of light......

Lin Wang has been trapped for these years, although his cultivation has not improved, but the technique of manipulating the Hades seal has become more and more proficient, at this time Lin Wang has exerted eighty percent of the power of the Hades seal, only to see tens of thousands of lights slowly gathered together, turned into a powerful sledgehammer, the surrounding yin qi rushed towards the big hammer like crazy, with the continuous influx of yin qi, the size of the big hammer became larger and larger, and after a while, it increased dozens of times, becoming a huge sledgehammer.
