"What are you afraid of, Zhou Daqiang dares to go down, what do I have to scruple about, besides, Zhou Daqiang is related to the secret record of the magic pattern, and I have to break through the sword mountain and the sea of fire!" Lin Han made up his mind to kill Zhou Daqiang, although this person is not a climate for him now, his potential is too terrifying, and now he has become a mortal enemy, and it is really difficult for Lin Han to feel at ease if he does not get rid of him.

Hearing Lin Han talk about the Secret Record of the Demon Pattern, Dudu didn't say anything more, in its opinion, in order to unlock the secret of the Secret Record, it was worth taking a risk.

Lin Han summoned the black magic vine, turned the rattan into a hard stick, grabbed the middle section of the rattan, and stuck on both sides of the cave wall, sliding downward, this hole is unfathomable, and the further down the light, the darker the light, Lin Han always controls the speed of the slide.

"Why is this hole so deep?" Lin Han was surprised, now that he had been diving for about five minutes, it was already completely pitch black, and with Lin Han's third-order evolutionary eyesight, it was almost impossible to see, according to his estimate, he had at least slid down for thousands of meters, could it be that this hole went straight to the center of the earth.

The further down he went, Lin Han felt that the evil bloody aura became more and more intense.

After another two minutes or so, a faint red glow finally appeared in the darkness below.

Lin Han immediately came to his senses, and dived to the vicinity of the red light, which was a translucent light curtain that seemed to be composed of flowing blood, and when he looked down through the light curtain, he could vaguely see that it was a blood-red world.

"What is this?"

"If this is really a secret realm, this should be the entrance to the secret realm." Dudu said.

Lin Han didn't dare to be careless, and stretched the black magic vine downward, and the black magic vine instantly penetrated the light curtain.

Lin Han withdrew the Black Demon Teng and did not perceive any danger, so he jumped down and entered the light curtain.

This is a world full of blood-red, mountains, rivers, earth, and rivers of blood, there is a bloody breath rippling in the air, and the sky is blood-colored, like a world shrouded in blood-colored light curtains.

"This is the secret realm?" Lin Han looked around, but did not see Zhou Daqiang's figure, the entrance of the secret realm was suspended more than ten meters behind him, in addition, next to Lin Han stood a huge blood-colored stone stele, on which were written two huge inscriptions that Lin Han could not understand, obviously I don't know which civilization's handwriting.

"Blood Hole!" Utter the meaning of the inscription.

"Blood Hole?" Lin Han asked, "Could it be the name of this space?" ”

"I know, this is actually a secret realm for the formation of blood caves." Dudu seemed to remember something, and then said: "Lin Han, don't be careless, the blood cave is a very terrifying dangerous place in the ancient Xiuzhen civilization, where many powerful demons were born, and legend has it that the blood cave was finally destroyed by the Shushan Sword Sect, and the whole faction destroyed it, but I didn't expect that a secret realm was formed here." ”

"Roar!"

"What sound?" Lin Han was listening attentively, but he was startled by the sudden roar and hurriedly looked.

Within a river of blood not far from him, a figure made of blood suddenly rose.

This strange scene made Lin Han feel his scalp tingle.

The figure gradually broke away from the river of blood and gradually became clear, and its facial features were almost the same as those of humans, but they were completely composed of dark red liquid, which looked very terrifying.

Blood Demon Golems, low-level creatures in the bloodfield, have low intelligence, and suck the flesh of living beings.

This thing is called a Blood Demon Puppet, it is just a low-level creature, and the detection skills that come with the Heavenly Demon Pupil made Lin Han understand the strength of this monster in an instant.

But even so, Lin Han didn't dare to be careless, and from a distance, he manipulated the black demon vine to hit it.

The speed of the Blood Demon Puppet was not fast, it was only equivalent to the level of a first-order hell beast, and the black demon vine hit its body, but the next moment, Lin Han was suddenly stunned.

He saw the black devil vine hit the body of the blood demon puppet, and a large amount of blood was splashed out, and the body of the blood demon puppet was also turbulent, and then the blood demon puppet let out an angry roar and approached Lin Han step by step.

Obviously, the blow just now didn't do much damage to the Blood Demon Golem.

"It's physical attack immunity!" Lin Han immediately understood that this thing was completely condensed from the water of the Blood River, and ordinary physical attacks could not hurt it at all, which was very similar to the resentful spirits that Lin Han had encountered.

The last thing Lin Han wanted to face was an enemy immune to this kind of physical attack, because what he lacked was the means of energy attack.

The means of energy attack, Lin Han now has two kinds of Dutian Demon Fire and Thunder Light Cannon, and in terms of defense, there is Yuan Energy Shield, but Dutian Demon Fire consumes Lin Han's spiritual power, and the consumption of spiritual power is extremely fast for Lin Han, and the Thunder Light Cannon consumes Yuan Li very much, and Lin Han's peak state can only be used three times in a row, Lin Han has used it once against the Earth Dragon Beast before, and now the Yuan Force in his body is only about seven layers at its peak.

Therefore, as a last resort, Lin Han was unwilling to waste his Yuan Strength rashly.

Seeing the Blood Demon Puppet getting closer and closer, Lin Han frowned, and a black demon flame suddenly appeared in the palm of his hand, it was the Dutian Demon Fire, Lin Han pointed at the Blood Demon Puppet from afar, and the wisp of Dutian Demon Fire suddenly flew towards the Blood Demon Golem.

"Zila......" This slight wisp of Heavenly Demon Fire made a piercing sound as soon as it touched the Blood Demon Puppet, and then the Blood Demon Puppet let out a wailing scream, and the next moment, suddenly the whole thing turned into a white smoke and dissipated without a trace.

This is another method that Lin Han thought of using the Dutian Demon Fire, using the Dutian Demon Fire in this way can greatly reduce the consumption of his spiritual power, but what Lin Han didn't expect was that the Dutian Demon Fire was actually so lethal to creatures immune to this kind of physical attack.

In addition, Lin Han saw that after it was extinguished by the Dutian Demon Fire, a bright red bead appeared on its chest and fell to the ground.

Lin Han picked up the bead, and in an instant, the message of the bead appeared in his mind.

First-level Blood Demon Beads, Mutant Yuan Crystals, and eating Blood Demon Beads can get a large amount of life energy.

It turned out to be a mutant elemental crystal, Lin Han was very happy, each of the mutated elemental crystals was extremely precious.

"The secret realm is often a battleground for generations of evolutionaries, and his role is no worse than the ancient ruins in many cases, because every secret realm is a space that exists for a long time, and exists in the turbulence of time and space, and is not under the constraints of the rules of heaven and earth, so unless there are no living beings in the secret realm, once there are living beings in it, then, after countless years of baptism, the creatures in the secret realm have a great chance of mutated creatures, and there will be mutant crystals in the bodies of mutated creatures." Dudu explained to Lin Han.

"Especially the blood cave is a secret realm that existed in the primeval period, after such a long time, I am afraid that the creatures here have all become mutated creatures, Lin Han, this is a big opportunity, maybe you can break through the fourth order here!"

Lin Han didn't expect that there were so many benefits in the secret realm, he had just killed the blood demon puppet and didn't get the slightest life element, Lin Han was secretly depressed, he didn't expect to get a mutated element crystal that could provide him with life energy so quickly.

Lin Han spit out this blood demon bead in one bite, and immediately noticed that the life element energy in his body had increased slightly, the life element energy provided to him by this bead was not much, probably only comparable to the life element energy provided by the second-order prison beast, but Lin Han did not feel frustrated at all, this was only a first-level blood demon bead, which showed that the blood demon puppet was only the lowest first-level life in the secret realm, if it was a second-level, third-level, or even fourth-level creature, what would happen to their mutant elemental crystals?

I just don't know how many mutated creatures are in this blood cave? Lin Han faintly looked forward to it.

At the same time, in the depths of the Blood Cave Secret Realm, Zhou Daqiang was running wildly in a huge cave.

This huge cave is getting wider and wider the more it goes inside, and even two huge blood rivers appear on both sides, and the endless blood water is filled with grumbling blood bubbles, perhaps it is the sound of Zhou Daqiang's running that awakens the creatures in the blood river, and from time to time there will be a blood-colored figure appearing in the blood river on both sides, but after feeling the breath on Zhou Daqiang's body, they have disappeared in the blood river again.

Zhou Daqiang ran all the way to the deepest part of the cave, here, floating in the air a giant heart as tall as three or four floors, this huge heart was passed through by more than a dozen huge iron chains, and in the hidden cave wall at the other end, the iron chains were carved with dense complex patterns, in addition, the cave walls were also covered with runes.

Under the huge heart, there are many tubes like blood vessels, connecting the left and right rivers of blood, and a large amount of blood is constantly circulating between the blood rivers and the heart as the heart retracts and shrinks.

Zhou Daqiang came to the giant heart, knelt down on his knees and touched his head to the ground.

"Zhou Daqiang, see the ancestor!"

"What did you come to me?" Suddenly, an old and majestic voice came from the cave.

"Ancestor, my foundation outside has been destroyed, and there is a powerful evolutionary who wants to kill me, so I hid in the blood cave." Zhou Daqiang said tremblingly.

"Rubbish! I have already given you the origin of demon blood, and you have the breath of the ancestor on your body, and the hellbeast can't hurt you at all, but I didn't expect to be chased and killed here by the evolutionary, what's the use of leaving you? The voice said angrily.

"Ancestor spare your life, ancestor spare your life......" Zhou Daqiang sweated drippingly, and kept kowtowing and begging for mercy.

"Well, since that person has already come in, then he will eventually find here, hehe, the ancestor has one more evolutionary to find flesh and blood for me, and the entry will definitely be faster, if it goes on like this, the ancestor and I are not far from the day of getting out of trouble, hahaha......" The entire cave trembled in this laughter.

Lin Han picked up the Blood Demon Bead, this was already the fifteenth Blood Demon Bead he had harvested, the more he went inside, the more frequent the Blood Demon Puppet appeared, although these Blood Demon Puppets looked weird, but their real strength was vulnerable, Lin Han even found that as long as they attacked their chests with the Black Demon Vine and knocked the Blood Demon Bead out of their bodies, these Blood Demon Puppets would immediately turn into a pool of blood, in this way, it would be more convenient for Lin Han to deal with these Blood Demon Puppets, and he would no longer have to consume spiritual power to use the Heavenly Demon Fire.
