Getting rid of those psychic gladiators who were in hot pursuit, Lin Feng cleared some monsters that stood in the way on the road, and his experience increased by about 3%. After level 15, the level of experience is the sum of level 13 and level 14, and it takes a lot of time to level up.

It wasn't until he ran to a safe place that Lin Feng stopped. There are no monsters or players around, so it's just the right time to take a break.

Lin Feng's package contained the things he had just gotten from the treasure chest, and he took it out and placed it in the palm of his hand.

This is a pitch-black stone, the size of a fist, but there is a white light floating on it, this Lin Feng is recognized, this is life energy.

It is said that in ancient times, there was a profession called the Dark Rites, which used powerful life energy to resurrect the dead, giving them half of their energy before they died, thus driving these people to die for them.

This method is extremely evil, and it is naturally impossible for the priests to allow the existence of the Dark Sacrifice, they believe that this is to discredit the light of the angel camp, so they send countless soldiers to kill them until the Dark Sacrifice is exterminated.

However, such a large group is not wiped out, and there may be remnants of those who have been caught.

There were also ancient words carved on the stone, which seemed to be sacrificial words, and Lin Feng could only get some vague information from them.

"Blood...... Indenture...... Dark Sacrifice..."This is all the information that Lin Feng can get, he frowned and groaned, this thing called the Blood Pact Stone seems to be very good.

It's a rare thing, and if you sell it, you're sure to get a good price. However, Lin Feng is not stupid, the person who can take special items to sell is the kind of person who is more than 2 and does not know the goods. You must know that every special item in eternity has some unknown effect, it may make you go to heaven in one step, or it may make you fall into hell, who knows.

The meaning of life is originally a gamble, and gamblers are always hovering at the gates of heaven and hell, and because of this, they attract countless people.

Lin Feng cut a crack in his thumb with a dagger, and blood seeped out of it.

Lin Feng dripped the blood on the Blood Pact Stone, and the blood seemed to have absorbed a sponge, and it only boiled for a short while before disappearing.

The Blood Pact Stone was dyed red, a bewitching red.

System: "Whether to summon a Blood Pact Knight."

"Yes." Lin Feng was stunned for a moment, but he quickly chose yes.

A puff of smoke emanated from the Blood Pact Stone, and the smoke gradually condensed, forming a knight riding a high-headed skull gate, dressed in black like a predator in the dark.

It seems that this should be the Blood Pact Knight.

[Blood Pact Knight], an elite summon.

After being created by the Dark Sacrifice with life energy, it was abandoned in the dark world and spent a long time alone in the wild, giving it a bloodthirsty character like a beast and tenacious vitality.

Health: 1000/1000.

The Blood Pact Knight looks good, Lin Feng just needs a meat shield helper, and right now, this new partner seems to be up to the task.

The attributes of the Blood Pact Knight are almost comparable to those of level 20 creatures, and there is a certain bonus in qi and blood, and it is estimated that it can resist the attacks of four psychic gladiators at the same time.

Lin Feng took a look, the summoning method of the Blood Pact Knight was similar to that of Goffett, and when he received it, he only needed to activate the Blood Pact Stone, and as for how to activate it, he could just take it out.

The Blood Pact Knight looked around a little confused, as if it hadn't been in the real world for too long, and it was a little overwhelmed.

However, when it saw Lin Feng, its expression still became much more respectful, and it jumped off its horse and half-knelt in front of Lin Feng.

"Huh..."The Blood Pact Knight snorted in a low voice, in respect.

This is probably some kind of unknown language, Lin Feng asked the Blood Pact Knight to get on his horse and follow him, and continued to hurry.

The Blood Pact Knight can come in handy at some point, and it can also add a few extra layers of insurance to Lin Feng's life safety.

Lin Feng continued to walk towards the Psychic Library, the further inside, the more barren the environment here became, but from the ruins of the wall, he could vaguely discern the former prosperity.

The Blood Pact Knight was very behind Lin Feng, his eyes were rolling around, although he didn't know what kind of expression was attached to his heavy armor, but Lin Feng was indeed very relieved, there was nothing more loyal to him than his entourage.

You can already see the door of the psychic library, and the blood-red giant gate that is ten meters high has an indescribable weirdness. As soon as Lin Feng arrived here with the Blood Pact Knight, several psychic gladiators surrounded him.

"Up!" Lin Feng added a stealth by himself, and at the same time gave an order to the Blood Pact Knight.

With a bang, the Blood Pact Knight slammed into a psychic gladiator with his skeleton horse, knocking it upside down and flying away. This is the unique skill of the Blood Pact Knight, the Charge of the Blood Pact.

Lin Feng's performance made Lin Feng very satisfied, and the reward for consuming a special item was really worth it.

Lin Feng passed past a psychic gladiator, who was about to rush towards the Blood Pact Knight, the broken knife in his hand had already been raised, just waiting for a partner to make up for its attack when it was over.

That's it!

Lin Feng was freed from the stealth, gave a hard blow, and the backhand backstabbed very skillfully and nailed to the backbone of the psychic gladiator.

The psychic gladiator had no blood, and its bones made a crunch and seemed to crack somewhat.

“335！” The output of the poison blade dagger was indeed not covered, and the psychic gladiator shattered into skull fragments and fell.

Lin Feng scooped up some of the items it had dropped, and just at this moment, another psychic gladiator attacked him.

Lin Feng lowered his head and body, and the normal attack + deboning was played one after another, killing this psychic gladiator.

The other two psychic gladiators were dragged to death by the Blood Pact Knight, and Lin Feng observed for a while, it was only a matter of time before they died.

The Blood Pact Knight was extremely brave, filled with the smell of blood, and his moves were fierce and fast, and here roared the neighing of skeleton horses.

Lin Feng turned around and ran towards the Psychic Library, where the Blood Pact Knight grabbed the monster, just buying him time.

As he got closer, the red giant gate appeared in front of him, and Lin Feng only found that there were deep nicks on it, these were all traces of sword magic.

What kind of attack is this, Lin Feng stretched out his hand and stroked it, and the traces had already penetrated into the door, and there was a feeling of cutting his hands. Lin Feng could imagine what a fierce battle broke out here at that ancient moment.

Lin Feng sighed silently for a long time, maybe the psychic library was also a battlefield full of dead souls. Pushing open the door, he stepped into the scene of the psychic library.
