With the disappearance of Lin Yi and Xiao Yu, more than a hundred blood demons once again appeared at the entrance of the first layer.

Lin Yi also learned about this from Xiao Yu, that is, after you kill a batch of blood demons, when you enter the second layer, another batch of blood demons will automatically appear at the entrance, which is also to hone the students.

If there is no such setting, after the first batch of blood demons are killed, all the students will be able to enter the second layer, and they don't know the danger of the second layer, for the sake of credits, some people with low strength will also be sent to death if they enter, so there will be blood demons guarding at the entrance of the second layer, and they will be eligible to enter the second layer only if they have the ability to kill these blood demons, otherwise they can only retreat.

............................................................

When Lin Yi and Xiao Yu entered the second layer, they found that the blood-red aura in the second layer was even stronger, and the fierce aura was even more.

Even Lin Yi felt particularly depressed, shook his head hard, and muttered to himself, "How strong is the fierce aura here?"

Xiao Yu, who was on the side, was also more or less affected, but then she adjusted it, and then glanced at Lin Yi.

"Lin Yi, let's separate from here, good luck. There was a smile on Xiao Yu's beautiful face, and then he quickly swept towards the depths of the second layer.

Lin Yi saw Xiao Yu leaving, and also looked around slowly, ready to find a place to familiarize himself with the situation on the second floor first.

According to the records in the books, the blood demon realm in the second layer has reached the middle stage of the art spirit level, but its strength is already comparable to the late stage of the art spirit level.

"Let's go ahead and have a look. Lin Yi glanced at the second layer of the boundless Demon Domain and muttered to himself.

In this way, Lin Yi has been walking in the second layer for seven days, and during these seven days, he can occasionally encounter a blood demon.

In seven days, Lin Yi only encountered a total of three blood demons, all of which were at the mid-level realm of the art spirit level, but it was also a little difficult for Lin Yi to kill.

Today is already the seventh day, and Lin Yi has only only harvested three second-level inner pills, which makes Lin Yi a little depressed.

He wanted to find some blood demons to kill and get Nedan.

"Flutter-" The flame sword in Lin Yi's hand suddenly stabbed out, and it happened to stab in the chest of a blood demon who was not in a hurry.

This blood demon was killed in an instant, and Lin Yi put away the flame sword and took out the second-level inner pill on the blood demon's chest.

"This is the fourth Blood Demon. Lin Yi looked at the blood demon he had killed and muttered to himself.

Seven days have passed on the second layer, how can I earn enough credits if I continue at this rate?

And just as Lin Yi put away Neidan and was about to leave, suddenly a figure quickly appeared beside Lin Yi.

"Lin Yi, I've been chasing this blood demon for a long time, but I didn't expect to be killed by you, you're really lucky. The person who came glanced at Lin Yi, then at the blood demon who was killed, and said in a low voice.

"Xiao Chengyu?" Lin Yi said.

"Hmph, even if you know each other and know me, now take out the second-level inner pill that belongs to me, and then I will give you all the inner pills you have obtained in the past seven days, and I may be able to let you go." Xiao Chengyu said coldly.

Lin Yi was stunned, this Xiao Chengyu actually caught his attention?

"There are many crises in this demon domain, even if I kill you, the high-level officials of the Blue Emperor Academy will not know, they will only think that you are not strong enough to be killed by the blood demon, hahaha. Xiao Chengyu seemed to be very confident in killing Lin Yi, with a smile on his face.

"I've also changed my mind, I wanted to let you go, but now I'm in a bad mood, you take out all your inner dan, and you can get out of my sight. Lin Yi always had a smile on his face and said loudly.

When Xiao Chengyu heard this, his face changed, and he said in a low voice: "Lin Yi, don't be ignorant, although you are the first on the freshman list, you are always just a freshman, dare to provoke me, are you ready to die?" Xiao Chengyu looked hideous and roared loudly.

Originally, Xiao Chengyu was a little dissatisfied with Lin Yi's provocation of Xiao Tianhang, but he didn't expect to meet Lin Yi in the Demon Domain this time, Xiao Chengyu thought that his combat power comparable to the peak of the art spirit level could definitely defeat Lin Yi.

"Nedan is on me, if you have the ability, you can take it. Lin Yi said coldly, not giving Xiao Chengyu face at all.

"Lin Yi, be a man in the next life, keep your eyes open, don't offend people. Xiao Chengyu roared loudly, and at the same time, Xiao Chengyu also burst out with his powerful combat power.

"Die, Lin Yi!" Xiao Chengyu clenched his fists, gathered energy, and blasted directly towards Lin Yi.

"Hmph! Lin Yi saw Xiao Chengyu's attack, snorted coldly, and directly cast the afterimage of the breeze.

Nine phantoms appeared around in an instant, and there was a strong energy surge on top of the nine phantoms, and Lin Yi controlled these nine phantoms to attack towards Xiao Chengyu.

"Shock!"

Lin Yi shouted, and directly cast the shock seal, he wanted to fight quickly, after all, this is the Demon Domain, and it will not be good if something happens.

As soon as the shock seal was cast, the surrounding air was constantly trembling, and one after another fists appeared on Lin Yi's fist.

After Xiao Chengyu saw this scene, he sneered, and directly showed his most proud boxing technique, colliding with Lin Yi's fist.

"Boom!"

There was a loud bang, and in a clearing in the second layer of the Demon Domain, a stormy wave was set off, and the collision between Xiao Chengyu and Lin Yi directly caused him to take three steps back, but Lin Yi did not retreat a single step.

"Lin Yi, you damn it!" Xiao Chengyu felt that Lin Yi's attack power was much stronger than he imagined, and roared with a hideous face.

"Hmph, since you choose to be a hunter, then you must have the consciousness of being killed by the prey. Lin Yi said in a low voice.

Xiao Chengyu moved, he was completely angry, and wanted to kill Lin Yi.

"Lin Yi, even if you give me all the Neidan now, I won't let you go, you only have one way to die. Xiao Chengyu roared loudly.

In an instant, the flying sand and rocks swept across the sky, the fire burned the earth, and the lightning emptied the thunder!

Xiao Chengyu directly used his own killing moves, all of which attacked Lin Yi's body, but all his killing moves failed, and what was shattered was only Lin Yi's phantom.

The afterimage of the perfect breeze is difficult to distinguish between the true and the false.

"It's time to finish. Lin Yi watched Xiao Chengyu make a trick and said coldly.

A faint sword light seemed to come from nothingness, breaking through Xiao Chengyu's protective defenses in his horror, and the sharp edge on it made his heart contract instantly.

But when Lin Yi wanted to further stab Xiao Chengyu, Xiao Chengyu directly dodged at the cost of being stabbed in the arm.

Lin Yi's flaming sword stabbed straight towards Xiao Chengyu's heart, which is also one of the weaknesses of human beings!

Xiao Chengyu flew up and dodged directly, but his arm was stabbed by Lin Yi's fiery sword, and Xiao Chengyu, who landed on the ground in the distance, had one arm hanging down at this moment, obviously seriously injured.

"Why can you avoid our attacks. Xiao Chengyu roared, he was extremely unwilling, this attack should be foolproof.

After Lin Yi's afterimage of the breeze is complete, the nine phantoms do whatever they want, and more importantly, there is a trace of wind in this afterimage of the breeze, and it is impossible to capture Lin Yi's body.

Until this moment, Lin Yi completely killed Xiao Chengyu, if his strength was not strong just now, Xiao Chengyu would have killed himself, his methods were too fierce.

"Xiao Chengyu, you should have had such an awareness a long time ago. Lin Yi snorted coldly, and the artistic conception of the wind combined with the afterimage of the breeze swept directly in front of Xiao Chengyu.

Xiao Chengyu wanted to dodge, but because of his arm injury, he couldn't dodge at all.

After a few changes, Lin Yi's flaming sword separated Xiao Chengyu's fist, and a sword slashed through his neck, and blood spurted like a spring.

"You ......" Xiao Chengyu pointed at Lin Yi and couldn't speak, covering his neck with one hand and falling down with his eyes full of unwillingness, he was really unwilling, the ending shouldn't be like this, it should be Lin Yi who died instead of him.

Until he died, Xiao Chengyu did not have any regrets, such a villain did not die, it would only bring more unnecessary trouble to Lin Yi.

Originally, Lin Yi didn't want to kill Xiao Chengyu, but Xiao Chengyu was murderous to him, if he didn't kill Xiao Chengyu, he would be killed by Xiao Chengyu.

Before Lin Yi came to the Demon Domain, he had also learned about the Demon Domain, and the Qingdi Academy would not care about what happened in the Demon Domain.

In the Demon Domain, no matter what method you use, as long as you can come out alive, you can, even if you kill other students, it is not impossible, therefore, every year when the Demon Domain is opened, there will be a few students who die in it, they are either killed by blood demons or killed by their companions, and these people are all people who are greedy for small gains, if they can't even survive in the Demon Domain, what qualifications do they have to cultivate in the Qingdi Academy?

What the Qingdi Academy wants is a genius, not a mediocre talent!

When this system came out, it was opposed by many teachers for a while, but after observing what happened after the opening of the Demon Domain in recent years, these teachers all acquiesced.

At this point, an unwritten rule in the Demon Domain spread, that is, in the Demon Domain, you can shoot at anyone.

Of course, there are many people who have grievances, and they are all resolved in the Demon Domain.

Lin Yi walked in front of Xiao Chengyu, then picked up Xiao Chengyu's space rune, and with a movement of his mind, he entered the space rune.

Among Xiao Chengyu's space runes, there are actually fifteen second-level inner pills, and one hundred first-level inner pills, and the others are basically useless to Lin Yi.

Lin Yi put all the Blood Demon Inner Dan into the system space, and then pinched his fingers hard, and the space rune instantly shattered and turned into nothingness.

"Sure enough, the hunter Nedan came quickly. Lin Yi looked at Neidan in the system space and muttered to himself.

It took Lin Yi seven days to get more than a hundred first-level inner pills and four second-level inner pills, but after killing Xiao Chengyu, he got more inner pills than he gained in seven days.

Now the number of Lin Yi's inner pills has increased a lot, the number of first-level inner pills has reached 200, and the number of second-level inner pills has also reached as many as nineteen.

After killing Xiao Chengyu, Lin Yi quickly left the place of battle, and then continued to look for the second-level blood demon. (To be continued.) )
