Qi Dong carefully observed the outside of the meeting through the cat's eye, and felt that there was no problem, so he walked out of the room.

The corridor was silent, and the people hiding in the room did not dare to make any noise, for fear of attracting murderous kobolds.

The slightest smell of blood came up from downstairs, Qi Dong frowned secretly, such a strong smell of blood will attract more kobolds, and the lone kobold upstairs must be dealt with as soon as possible, otherwise it will be dangerous.

The sixteen-story residential building they were in didn't dare to take the elevator for fear that the sound of the elevator would attract the attention of the kobold. You can only take the stairs and look for the kobold who has gone up one by one.

Qi Dong had changed into light sneakers in the house just now, his steps were light, and he barely made any sound when he walked.

He held the knife in one hand, across his chest. Although he is now limited by his physique, he can't play the sword skills he learned in his previous life, but he has rich experience and is naturally much stronger than ordinary people.

No kobolds were found on the fourth floor.

Neither on the fifth floor.

……

Not on the ninth floor.

"Hey, there's a voice!"

"Bang! Bang! ”

The sound of slamming the door is the kobold! It seems to be on the thirteenth or fourteenth floor!

Qi Dong's spirit was shocked!

Take a break, cheer up, and walk up.

"It's near! Fourteenth floor, it's here! ”

The kobold was still slamming on the door, probably because he had noticed someone in the house, so he kept watch here. The other kobold just now probably knew that he couldn't smash it open, so he gave up here and went elsewhere to find prey.

Qi Dong took a deep breath, clenched the knife in his hand, and cautiously poked his head out of the staircase entrance.

The kobold is smashing the third door on this level.

"Oh no, it's been discovered!"

As soon as Qi Dong poked his head out, the kobold stopped slamming the door and looked over this way.

Qi Dong was startled, but he didn't panic. Even if he didn't have a chance to sneak attack, he was confident.

"Woohoo!"

The kobold who found Qi Dong instantly became excited, screamed a few times, saliva in his mouth, waved his ugly but sharp claws, and rushed over quickly.

Facing the rushing kobolds, Qi Dong not only did not retreat, but instead met him.

The kobold's green eyes flashed with a hint of tyranny, and he roared like a hungry beast. When it was less than two meters apart, it jumped up violently, and its two claws were outflanked from the left and right in a closed hug, and its big mouth opened, revealing its hideous sharp teeth, and bit towards Qi Dong's neck.

"I knew you were going to do that!"

Qi Dong sneered in his heart, quickly bent down and squatted, and the kobold just pounced on top of his head and pounced.

And that's not all! While Qi Dong bent down and squatted, he quickly changed from holding the knife with one hand to holding the knife with both hands, without looking, and stabbed upwards violently! At this time, the kobold pounced on the top of his head, and with a "plop", the scimitar pierced through the kobold's lower body, piercing most of its body.

"Whew!"

The kobold howled miserably, Qi Dong quickly let go, the kobold lost his balance, threw himself forward a few meters in the air, rolled to the ground, convulsed a few times, and then whimpered, and the scimitar was still inserted in his lower body.

"Hoo ......"

Qi Dong breathed a sigh of relief, and wiped the blood that had been spilled on his body when he pierced the kobold with the knife just now with his sleeve, but fortunately he dodged quickly and didn't drip much blood.

The first encounter with the kobolds, a complete victory!

Don't look at Qi Dongsheng's ease, if it is a different person, even if he is a sanda champion, he may not be able to take this kobold, and the biggest possibility is that the kobold will easily tear off his head.

With his rich experience in fighting with kobolds in the early days of the last days of the previous life, Qi Dong predicted the kobold's next move before the kobold approached. Only then can you make an action in advance and pierce it in half.

The process went smoothly to his own surprise, and he was ready to be injured.

Fortunately, this kobold is not too strong, if he encounters an elite kobold, with his current physique, let alone killing it, I am afraid that he will not be able to hurt it, and it will be a problem for him to even escape. Even if the kobold's movements are predicted, the body reaction can't keep up.

Except for the neck and head, the kobold is the most fragile of the lower body, without a scaly skin, and the body and limbs are covered with a tough scaly skin. If it is an adult with little strength, I am afraid that it will not be able to break its skin with all his strength.

Qi Dong stepped forward, squatted down, slowly pulled out the scimitar that pierced the kobold's body, and then touched the kobold's abdomen.

"The scaly skin has softened, and this knife should be able to pierce in."

Qi Dong slashed open its abdomen, and the blood in the kobold's abdomen flowed down like tap water.

His face did not change, he stretched out his hand, and expertly rummaged through the kobold's abdomen, and the movements were so skillful that it was as if he had done it a thousand times.

"Found it!"

After rummaging for a while, Qi Dong's face was happy. A small black irregular crystal the size of a pinky fingernail was found from the kobold's abdomen. The crystal is translucent, moist and bright, and naturally transparent.

"Evolution Stone"!

The "Evolution Stone" is a magical thing that exists in the alien bodies that invade the Earth. It is precisely because of the discovery of the "Evolution Stone" that the human beings on Earth have the ability to survive in the last days, instead of being ravaged by aliens at will.

Humans can fuse the "evolution stones" of different races, and after fusion, they can greatly improve the quality of the human body.

The "Evolution Stone" has the most significant effect on humans who have never been strengthened, and an ordinary kobold's evolution stone, when used on an ordinary person who has never been strengthened, can increase the physique by about 0.5 times.

When the physique reaches about five times the physique of ordinary people, it reaches a limit state, and the physique pauses to grow. At this time, if a certain amount of alien evolution stones are absorbed, a "evolution stone" will also be generated in the human body, and after the evolution stone is generated in the body, the physique will continue to grow.

However, the strange thing is that after the human who generated the evolution stone dies, the evolution stone generated in its body will also dissipate immediately, and it cannot be stored for a long time like the evolution stone of the alien race. This also dispels the idea of some vicious humans killing their own race to obtain the Evolution Stone.

In order to distinguish the different evolution stones between humans and aliens, humans call the evolution stones generated in their own bodies "Neidan".

Since the newly generated "Inner Dan" of human beings is also black, humans with Inner Dan are called "black iron-level" humans. The newly generated Evolution Stone (Neidan) is only the size of a little fingernail, and this stage of strength is called the "Black Iron Rank Zero Order".

Later, as the evolution stones of the alien races were continuously absorbed, the inner pill in the human body continued to increase, and its physical fitness also continued to improve. The maximum size of the Inner Dan is the size of an egg, and at this time it is called the "Black Iron Ninth Order".

Ordinary kobolds also contain little fingernail-sized evolution stones in their bodies, so the strength of kobolds is also defined by humans as "black iron level zero order".

Although the level of ordinary kobolds is set as "Black Iron Level Zero Order", their physical fitness is only about three times that of ordinary humans, and the "Black Iron Level Zero Order" humans who generate "Neidan" in their bodies have the worst physique and five times their physique. Therefore, after a period of time after the end of the world, almost all humans of the same level can easily torture and kill kobolds. At present, the murderous kobolds have regained their tragic cannon fodder status, falling to the bottom of the biological chain, and even some hungry humans often hunt kobolds for food.

However, not all aliens of the same level are physically weaker than humans. Some aliens are gifted, and their physique is several times that of a human at the same level.

In the past, Qi Dong's demon hunting group had encountered a tiger-headed man royal family, and it only had the strength of the eighth order of black iron, and it actually had a tie with the demon hunting group. You must know that there were seven people in the demon hunting group at that time, and all of them were the strength of the eighth order of black iron, and in this case, they couldn't help the tiger-headed man, and in the end, the two sides could only stop.

"The first pot of gold is here!"

Qi Dong looked at the evolution stone in his hand excitedly.

He forcibly suppressed his excitement, opened his mouth, and directly threw the evolution stone like black jade into his mouth. I didn't expect the seemingly sturdy Evolution Stone to melt in your mouth.

The evolution stone was completely integrated into Qi Dong's body, and he snorted comfortably, followed by a crackling sound from his body.

"It's still so comfortable when I strengthen my body, I really want to come a few more times."

Qi Dong stood up and carefully felt his current physical condition.

"Yes, I have strengthened my physique by 0.6 times, and my current physique is equivalent to 1.6 times the human physique. My body is much more relaxed than before, my reaction is faster, my hearing and vision are sharper, and my strength is greater. ”

"Wow!"

Suddenly, the kobold's eager bark came from downstairs.

"Huh? It sounds like the kobold who left just now, why did he come back? Qi Dong said, "Didn't it go far just now?" Hmph, it just so happens that I have strengthened my physique, so you will be my next prey. ”

Qi Dong took a few steps back, ready to meet the enemy.

"Huh? No, listening to the footsteps, it doesn't look like one? ”

He looked at the staircase with a solemn face.

One!

Two!

Three!

Qi Dong's complexion changed greatly!

"Why are there three! Could it be that he left that one just now, to find a companion, in order to smash open the door? The one I killed was only the ...... in charge of stalking."

The three kobolds who had just come up had already found the corpses of their companions on the ground, and they glared at Qi Dong viciously because they were stimulated by the blood of their companions, and their mouths kept whining.

Qi Dong's eyes stared at the three kobolds without blinking.

"There is no way but to harden it! Hmph, it's more dangerous than this, I don't know how many times I've encountered it, and I'm afraid that you won't succeed, come on! ”

Meet on a narrow road, brave! He who! Victory!
