With more than ten years of cultivation, Han Cao Kou finally cultivated the Blood Dying Sword Technique to the thirtieth layer. There are still twenty layers of exercises from Dacheng. Only when you reach the 50th level of Great Perfection can you bring the power of this sword technique to the extreme.

As the technique improved, Han Cao Kou could feel that the sword embryo in his body was becoming more and more powerful, and it became easier to control.

I saw that his consciousness moved, and a transparent finger-long sword qi spit out from his body and slashed towards the stone wall.

Hearing a snort, a sword mark as long as a zhang appeared on the stone wall, and the depth could be an inch. Such power is already terrifying without a sword.

And the synchronization of cultivation and cultivation is only the beginning, if you want to kill people and take your life, you have to cultivate the swordsmanship in it. The cultivation of exercises only takes time, and the cultivation of swordsmanship is not so simple. Success often requires the assistance of external objects.

Just as Han Cao Kou was thinking about his next plan, suddenly his whole soul went numb, and then he couldn't move, and then he flew to a strange world in his heart with a grunt.

From the outside, the Grass Cub sat on the ground, its head hanging strangely and falling into a soulless state.

As he regained consciousness, he realized that he had appeared in a mysterious space as a soul. This is a stranger place than the place where the two stone tablets are kept.

"Xiao Xuzi, Sleepless King, is it the ghost of the two of you? It's not the first time you've met, why do you still like such a trick?" Han Caokou stood on the withered yellow grass, thinking in his heart, I don't know if the two babies Xiao Xuzi and Sleepless Jun woke up.

It was much darker, and there was no sun at the head, only a half-moon crescent, which emitted a dark light of the stars.

There are mountains and rivers around, but in the starlight, it doesn't seem to be alive at all. Whether it was the stream or the mountains, they all exuded a gloomy dead air.

There was no response to the shouts, and the cold grass roamed around at will. There are no people here, and there is no noise, and the silence is particularly quiet.

Soon, Han Cao Kou was attracted by a strong black gas.

As he walked around, he finally found the black withered wooden sword stuck upside down in the grass.

"Is this a wooden sword? Who left it here? At this point, Han Caokou still thought it was a hint from the babies.

No one answered the question, only the black wooden sword gradually buzzed as the Grass Kou approached. At the same time, a suction gushed out, and he voluntarily placed his hands on the hilt of his sword.

Han Cao Kou was taken aback, he didn't know what was going on, and the mana all over his body poured out, and he immediately stabilized his body.

Unfortunately, it was too late, and both hands were already gripping the hilt of the black wooden sword. No matter how the mana gushes out and rebounds, it is helpless.

Immediately after, countless tiny vine strands emerged from the hilt of the wooden sword, piercing into his hands under the frightened gaze of the cold grass kou. It swelled up along the vine silk, and it could be seen that the essence and blood in the body were extracted by it gurgling and poured into the wooden sword.

Only a third of the essence blood in his body disappeared from his body, and Han Caokou, whose face began to turn pale, was extremely panicked. If it continues like this, I'm really going to die here.

Suddenly, the sword embryo in his body rotated, and a three-foot-long sword qi quickly condensed outside his body.

There is no other way, Han Caokou is desperate to hold on to his life and get out of trouble if he doesn't want it.

However, at this time, the vine silk suddenly returned to the cage and no longer absorbed the essence blood, and suddenly bounced back a few steps from the cold grass.

Surprised and unsure of the Han Cao Kou, what he didn't want was to turn his head and fly away.

The black wooden sword on the ground pursued it with the momentum of breaking the wind, and hit the cold grass with a muffled snort.

A cluster of stars suddenly appeared, and I saw the cold grass falling from the sky for no reason. When he got up, there was no trace of the black wooden sword, and when he looked left and right, he didn't notice any discomfort in himself.

Soon, Han Caokou forcibly left this strange world and returned to his body.

With the departure of the Cold Grass Kou, a mysterious person with black eyes appeared in the dark night world. He stared at the vanished wooden sword on the grass, and suddenly closed his eyes and sighed. "O king, you have finally embarked on this road of no return. This, I'm afraid, is fate. ”

In the cave, Han Caokou woke up sweating profusely, and his face was pale and abnormal.

I didn't expect it to be so dangerous to absorb the soul here, and I almost lost my life, and I don't know what the hell it is.

"Huh, what is this?"

When I touched my left hand, I felt very hot, but my right arm didn't feel any discomfort.

"Could it be?。。 With a heart of speculation, a wave of mana emerged from Hancaokou's left hand and sucked the cross violently. Suddenly, a black light shone out, and a wooden sword three feet long, with a withered and smooth body, and no blade at all, fell into the air.

"What is this? Why did you follow me? It's weird. Han Caokou frowned and muttered to himself, and specially waved the wooden sword in front of him to take a look.

This wooden sword is extremely ordinary, without a trace of aura. The appearance is strange again, not like the spirit sword, refined iron with a blade.

And according to Han Caokou's cognition of refining, this wooden sword does not have any alchemy techniques. It's more like a naturally formed wooden sword, and it can't be counted as a mortal weapon in the innate period, let alone a treasure of the level of magic weapons and spirit weapons.

"Night Wooden Sword?" When he looked closely, Han Cao Kou obviously noticed that there were four obscure characters engraved on the hilt of the wooden sword.

As Han Cao Kou held the hilt of the sword with his bare hand and swung it at will, he only felt that the wooden sword was a little lighter, without a trace of weight, just like an ordinary wood in the mortal world.

And no matter how you inject mana, you can't wield any damage supernatural powers.

Suddenly, a depressed color appeared in Han Caokou's heart. "Such a toss, in the end of a waste, wouldn't it be impossible to play me?"

Then, Han Caokou used the crimson red flame to burn it, thinking that the two useless places would be burned clean and disappear into the world.

The strange thing is that the thousand-year-old Fei Phosphorus Flame is unable to incinerate it. And there was no sign of melting, and the skin was still so dry and dry, not damaged at all.

Crimson Red Flame is already the most lethal means that Han Caokou can use now. Other than that, there is no other supernatural power that can burn it.

After a few more days of trying, Hancao Kou reluctantly gave up. In the end, he ignored the night wooden sword and threw it directly into the cross mark on his right arm.

Such an accident also wasted a few days of Han Caokou's time. However, for immortal cultivators, a few days is nothing.

Soon, Hancao Kou forgot about the Night Wood Sword.

In the following time, Han Caokou did not hide in the cave mansion all the time to cultivate. Instead, they spent a lot of time running out of the island, tinkering with something in the sea on the edge of the cliff.

At first, it can be seen refining a fragrant spiritual liquid. Later, I saw that the sea was full of flags within a radius of 100 zhang, and the flag array spread out and the spiritual light shrouded the area within 100 zhang.

Then, after waiting for a meal, there was a surge of water under the seabed. Dozens of krakens in the Innate Stage realm seemed to smell some delicacies of the mountains and seas, and one by one they jumped out of the sea with red eyes and pounced on the white jade bottle filled with spiritual liquid.

Unfortunately, before they could get close to the bottle, dozens of spiritual energy bows and crossbows within the flag array trembled and pierced through their eyebrows or heads, and they died tragically on the sea.

Seeing more and more krakens appearing, Han Caokou finally meditated without moving, and he didn't open his eyes. Let the Kraken pounce, and then die in the forbidden position of the banner array.

In just seven days, a layer of ten-zhang giant high kraken corpses has been stacked on the surface of the sea.

It's not for nothing that Hancao Kou is so boring. The cultivation of the Blood Soul series pays attention to the cultivation of essence blood and soul. If you want to continue to improve your exercises or practice swordsmanship, it has a lot to do with these two things.

The Kraken contains the beast core in its body, and all the essence is inside. What the Cold Grass Kou wants is the beast core.

The innate beast core essence is too small, and it can't get into the eyes of the cold grass, so naturally it will not collect the corpses of the many krakens in front of him.

And the Demon Pill Essence Yuan is rich and strong, which is definitely a great help to the Blood Dying Sword Technique. However, the demon beasts or krakens that formed the demon pill were all Yuan Dan realm cultivators.

It is the Han Cao Kou who has stepped into the Yuan Dan period, but he doesn't think that he can kill the existence of the same realm at will now.

Therefore, for now, the only target can be placed on the Kraken in the Spirit Formation Period. Compared with the beast core in the congenital stage, the one in the spirit building stage is called the demon core.

The demon cores can be steamed and melted between them, and then the acquired demon pill can be synthesized by alchemy. Although Jing Yuan is a little worse, it is also a way that can be thought of now.

Beast cores, demon cores, and demon pills are all graded. There are ten levels of each type of conventional division, which is probably related to the cultivation of the demon beast itself.

The number of demons on the island is not large enough, far less than the number of endless krakens in the sea. What's more, this island is the only place where the cold grass is left here, and I really can't bear to attack its creatures.

In this way, the Chill Grass Kou set his sights on the sea.

It is said that there is a lot of harvest in this short period of time, and it will take a few days to attract the krakens who come up to the spirit building period. It's all about being able to collect demon cores slowly.

Just a few days later, something unexpected happened. I don't know if it's the reason for the blood flowing from the corpses of the endless krakens piled up on the surface of the sea, and the cross mark on his right arm shone brightly.

With a swoop, the withered night wooden sword flew out from the director, and then fell into the pile of kraken corpses regardless of the control of the cold grass coar.

Boundless vines spread out all over the sky, all piercing into the body of each kraken. As the vine silk slowly grew, the remaining essence and blood of the kraken were absorbed and devoured by it.

In just a few days, hundreds of thousands of kraken corpses on the surface of the sea were drained by the night wooden sword and all entered its body.

When Han Caokou was surprised, he even noticed that a seeping death aura burst out from the wooden sword. The corpse of the kraken, which had been drained of essence blood, shattered into wisps of spirit as if it had been provoked, and all of them poured into the wooden sword.

"This broken wooden sword can still improve its grade independently?What is the origin?" Han Cao Kou had already been surprised, and when he saw the flow of qi in the wooden sword's body increase, he really swallowed a mouthful of saliva and couldn't believe it.
