The Black Iron High Grade Mantis was larger than the average mantis!

  The black lines underneath the wings were also deeper.

  The killing power of the scythe and serrated teeth was, of course, also stronger.

  According to reason, Lu Yu’s current physical strength was only at the Black Iron Middle Stage.

  Even if the Scythe Mantis hunted by flying, it wasn’t fast itself.

  Lu Yu shouldn’t be its opponent either!

  However, someone had already said that reinforcement level is not the only criterion for judging a person’s strength or weakness.

  The advantage of humans was that their brains were better than these monsters.

  Not only would they use a variety of tools and weapons, they would also use tactics like sneak attacks and sound bites.

  Just like Lu Yu just now.

  First, he shot a mantis in the head with a crossbow, and while using its screams to attract attending another mantis, he used his supernatural ability to take it by surprise.

  Together with the Green Mantis Sword that had advanced to the Bronze level.

  The two mantises were no match for him.

  After finishing the two mantises, Lu Yu asked Yan Yun to find the crystal cores.

  Dazed, Yan Yun regained consciousness and hurried over.

  Hearing Yan Yun say that she could find the crystal core without cutting open the head, Lu Yu was still a little surprised.

  However, the surprise was only for a moment.

  It was because of the purpose of him bringing Yan Yun out!

  Apart from wanting to cultivate a relationship with Yan Yun and get the rewards from her earlier!

  He wanted to see what powers this woman had.

  Anyway, with his current abilities, as long as he played it safe, this woman wouldn’t be in too much danger.

  Now this woman’s ability, as if it is perception?

  The first one she didn’t perceive.

  The second one she perceived.

  Looking at this irregular transparent crystal with black lines in her hand, Yan Yun handed it to Lu Yu with a smiling face.

  It was as if being able to do something for Lu Yu was a very pleasing thing.

  ‘How did you know that what I was looking for, was it?’

  Lu Yu took the Black Iron Crystal Core!

  Looking at the somewhat delighted Yan Yun, the corner of his mouth also raised a smile.

  This woman’s ability seems to be special, ah?

  ‘Wasn’t it you who said that you were looking for gems with special energies?’ Yan Yun froze.

  Lu Yu corrected, ‘I mean, how did you find it?’

  ‘I don’t know. When I ran into that big lizard man before, it was like I could sense everything about its body!’

  Yan Yun replied honestly, ‘You said you were looking for something with the appearance of a pearl or a gemstone that also possessed a special energy. I just touched it and knew if it was there or not’

  ‘What kind of ability is that? Forget it, let’s talk about it later, Ding Feng, come and hide it first!’

  ‘Coming!’

  Lu Yu was a little puzzled, but he couldn’t afford to look deeper at this time, and hurriedly called Ding Feng back to the cashier’s counter.

  Ding Feng followed him to the cashier’s counter, and Lu Yu carefully examined the crystal core in his hand.

  [Attribute-less Crystal Core (Black Iron Grade): a type of crystal core that contains special energy. Consuming it after washing it will not only restore a large amount of physical strength but also allow the body to evolve once again].

  Note 1: There are two types of crystal nuclei: non-attribute nuclei and attribute nuclei. Consuming non-attribute nuclei can help human beings restore their physical strength and strengthen their bodies. Consumption of attributed crystals can help humans recover and strengthen their psychic abilities.

  Note 2: Ordinary people can use any ‘Black Iron Grade’ crystal nucleus, using whatever crystal nucleus may awaken whatever ability, but there will be a death rate. The stronger the energy of the crystal nucleus, the higher the death rate! Black Iron Class Non-Attribute Crystal Core (50% awakening rate, 50% mortality rate)]]

  Note 3: The unique abilities awakened by an awakened person will result in using different nuclei. Using nuclei other than those with unique abilities will not only have no effect, but may also result in side effects, and may even result in life-threatening situations, so please be careful when using them!

  Since it was the first time Lu Yu had obtained a crystal nucleus, the information seen by the Eye of the Villain was very comprehensive.

  There were three remarks in a row, and they dazzled Lu Yu.

  In a nutshell, it was just a few sentences.

  Crystal Cores not only had many grades but also many attributes.

  Although ordinary people could also use crystal cores and had a chance to become awakened after using them, they could only use Black Iron grade ones, and there was a high chance that the user would die directly after using them.

  Even if it is an awakened person, it can only use the crystal nucleus that matches its own ability, using a crystal nucleus outside of its ability. Not only does it not have any effect, but it may also have side effects.

  There was even the same chance of death.

  However, Lu Yu estimated that the mortality rate of an awakened person who used the wrong crystal core was definitely much lower than that of an ordinary person.

  Normally, it would be ineffective at most.

  Otherwise, what else would an Awakened person call an Awakened person?

  ‘Now that one has strengthened one’s body and also awakened the wind attribute supernatural ability, one can only use the crystal core with no attribute and wind attribute?’’

  ‘No, that’s not right. One can gain the protagonist’s ability by fucking the protagonist to death. If the protagonist has other alien abilities, then wouldn’t one be able to use crystal cores with other attributes?’

  ‘Seems to make sense!’

  Thinking of this, the corners of Lu Yu’s mouth raised into a smile!

  ‘Young Lu, this thing, what’s the use of it?’

  Seeing the smile at the corner of Lu Yu’s mouth, Ding Feng was a little puzzled.

  After they solved the monster, they would either continue on their way or find a place to hide?

  Looking for this thing?

  It was purely a waste of time!

  Not only did it burden everyone’s physical strength, it also increased the safety risks for everyone.

  ‘It can help us improve our strength!’

  Lu Yu did not hide it either.

  Although according to the normal story line, people would not discover things like crystal cores until several days after the beginning of the end of the world.

  It was only after several months that humans would know the effects! (The stuff in a monster’s brain, even if it’s nice to look at normally, people wouldn’t eat it indiscriminately.)

  Humans only popularized the crystal core’s role after a year.

  But to Lu Yu, this kind of secret was simply irrelevant.

  ‘Help us enhance our strength?’

  ‘How to enhance it?’

  ‘Just eat it!’

  ‘What? Eat it? Is that disgusting?’

  ‘Indeed, it’s disgusting, but you can’t eat it indiscriminately! Huh, on this, how come there is no stain at all?’

  Looking at the black iron crystal core in his hand, Lu Yu was a little surprised.

  Researchers grew the crystal core inside the mantis’ brain.

  Shouldn’t blood or brain matter have stained it when it was removed from the brain?

  But now, this crystal core with black lines was crystal clear.

  Where could one see half a stain on it?

  ‘This should also be my ability, right?’

  Yan Yun said with some uncertainty.

  ‘Another one of your abilities?’ Lu Yu narrowed his eyes. ‘Could it be that?. your ability also carries purification?’
