Song Jian followed the old man and walked all the way towards the end of the Shadow Block.

Along the way, almost all of the NPCs in the house began to whisper, and some even opened their eyes through the crack in the door and looked out.

"Another ......"

“…… Too powerful, maybe it can ......"

"That's our ......, hopefully he'll be able to ......"

Some whispering voices drifted into Song Jian's ears, and although it was not clear what they were discussing, it was obvious that their topic had been discussing around the task that Song Jian had taken over.

"Ahem~" The old man suddenly let out a cough, turned his head to look at the houses on both sides, and a sharp look bloomed in his originally cloudy eyes, and suddenly all the whispers stopped abruptly, and silence was restored.

"Warrior, let's go here, the library is ahead!" The old man looked like he was in his old age, and it seemed that he would be planted on the ground in the next moment.

Song Jian nodded, becoming a little vigilant.

"It seems that this hidden task of cleaning up the library is not as simple as imagined," Song Jian said secretly in his heart......

Soon, under the leadership of the old man, Song Jian came to a dilapidated small building.

This small building looks like a three-story building built by oneself in the countryside in the real world, and a lot of paint on the outside has been corroded and peeled off, revealing the cyan masonry inside, and it is surrounded by garbage and fallen leaves, and it looks like no one has cleaned it for a long time.

"It's been a long time since anyone approached this place because it's been occupied by demons...... old man sighed and said, "Warrior, the demons are in the library, please kill them all and restore the peace here!" ”

Song Jian nodded, didn't say a word, and walked directly towards the library, the old man stood in front of the door of the small building on crutches, staring intently at Song Jian's back until he disappeared into the library.

At this moment, a slanting sunlight shone from the side, and the old man's shadow suddenly became skewed, becoming much taller, and his whole body was covered with sharp thorns, and even on his head, two curved horns appeared.

Soon, the sunlight shifted away again, and the old man's shadow began to slowly disappear, as if everything just now was just an illusion.

……

Song Jian walked into the library alone, and as soon as he entered, he saw that the room was full of dust, the books on the wooden table had long been wrapped in dust, and even the bookshelves were covered with a thick layer of dust, and it seemed that no one had entered here for decades. It's more of a haunted house than a library.

At this moment, a translucent soul appeared from the corridor next to the bookshelf, and when it saw Song Jian, this soul body immediately roared: "Blasphemer, you invaders are all going to die!" ”

This translucent soul body appears to be covered in heavy plate armor and holds a two-handed sword in its hand, looking a bit like a medieval knight.

"LV15 Mutant Soul Body (Normal), Qi and Blood: 1900/1900, Spiritual Value: 500/500, Trait: Void Body, Skill: Slash, Jump Slash, Holy Light Slash"

"Void?" Song Jian frowned slightly, this name sounds very similar to a soul monster he met at the beginning, but that monster skill is called "Nothingness".

looked at the opponent's status bar, and sure enough, the virtual body effect is a 60% reduction in physical damage;

A simple physical attack, the damage to this monster is very weak, if Song Jian is a mage, it will be very cool to come here to kill monsters.

However, Song Jian was not helpless, and directly took out a bottle of "Salamander Elixir" and used it.

Suddenly, a burning flame appeared on the dark red Red Fire Heart Ape Sword.

The salamander potion can turn an attack into a fire attribute attack, and coupled with Song Jian's invisible sword aura, it is not too easy to deal with this kind of soul body monster.

Soul Control Swordsmanship!

A transparent long sword condensed above Song Jian's head, and with the swing of the Red Fire Heart Ape Sword in Song Jian's hand, this transparent long sword also slashed towards the mutant soul body.

Boom~

A series of more than two hundred points of damage floated up from the top of the mutant soul body's head, and the damage of the spirit sword was surprisingly high, almost every sword could hit double the critical damage, and for a while, the mutant soul body couldn't even get close to Song Jian, and could only passively bear the endless pain brought to it by the spirit sword.

Boom!

As soon as the three seconds arrived, Song Jian directly controlled the spirit sword to explode, once again causing more than three hundred points of qi and blood damage to the mutant soul body.

With just one skill, the qi and blood value of the mutated soul body in front of him was reduced to less than 1,000 points.

"It's easier than an assassin zombie!" Song Jian wielded his long sword burning with flames, used other sword techniques, and pounced towards the mutated soul body.

The mutant soul body screamed again and again, and without even releasing its skills, it was directly destroyed by Song Jian;

A heavy sigh sounded, the mutant soul body folded its hands, the armor on its body peeled off one by one, and the two-handed sword disappeared, and finally only a cloth coat remained, and a white light fell from the top of the mutant soul's head, absorbing the mutant soul body after death into the air and disappearing, leaving only a gray bead burning with white flames in place.

"Mutant Soul (White): Consumable, after use, can increase 30 Holy Damage for 30 seconds, the effect can be stacked repeatedly, up to 100;"

Song Jian picked up the mutant soul seed, although it burned white flames on the surface, but it was not hot at all, this kind of item, only against specific monsters can exert the greatest effect, Song Jian glanced at it, and threw it into the package bar.

Song Jian began to wander around the library, hunting down all the monsters inside.

"Is a soul body a demon? And these soul bodies look no different from humans, they shouldn't be demons, so where is the demon that the old man in that neighborhood said? Song Jian muttered to himself, full of doubts about the hidden mission he received.

Soon, a mutant soul body passed through a row of bookshelves and rushed towards Song Jian, and the two fought together, and it took Song Jian less than three minutes to kill the monster.

The experience points were very expensive, and this mutant soul body dropped another mutant soul seed, Song Jian didn't care, picked it up and put it in the package bar.

In this way, Song Jian searched on the first floor of the small building, and in more than half an hour, he turned around the entire library on the first floor, hunted more than thirty mutated soul bodies, and increased his experience value to 93% of level 14.

Moreover, what is strange is that these mutated soul bodies do not drop anything except for the mixed species, and each soul body will drop a soul seed, and these soul seeds can also be stacked, and now in Song Jian's package column, there are already thirty-nine mutated soul species.

The hall on the first floor was searched by Song Jian, and just as he was walking to the stairs and preparing to go up to the second floor, he suddenly saw a book emitting a faint white light on a crooked shelf.

"What is this, it seems to be something that can be picked up......" Song Jian couldn't help but walk towards the book.
