On the right side of the third floor of the hotel, there is a conference room of nearly 200 square meters, Lin Han led everyone here, everyone first closed the door in the middle and the small door behind, and then lifted the large air conditioner in the conference room to the front door and firmly held the door, which gave a little sense of security.

After calming down, many classmates began to think about their relatives, and many girls kept crying.

Lin Han saw this, but he didn't know how to comfort him, compared to them, he was lucky, since the death of the old dean ten years ago, Lin Han no longer had relatives, and the only person he was concerned about over the years was also said goodbye to him two years ago, even if he was concerned, he didn't know where she was.

"Still can't get through on the phone?" Lin Han asked.

"It didn't work, we all tried, the signal was completely interrupted!" Li Dong sat on the chair next to him and said with a sigh.

……

For a whole afternoon, Lin Han did not rest, but with more than 20 male classmates in the class, most of the materials in the hotel storage room were transported to the conference room, after all, now that the monsters were rampant outside, Lin Han did not dare to rashly lead everyone out of the hotel, and judging from the current situation, no one knew how long they would hide here, so it was natural to take precautions and prepare early, fortunately, this is a hotel, and the food is not worried.

At more than six o'clock in the afternoon, the sky gradually darkened, Lin Han climbed on the roof of the hotel alone, at this moment the space crack suspended in the air has long disappeared, Lin Han looked into the distance, only to see the original noisy city at the moment quiet and terrible, from time to time you can see all kinds of strange monsters shuttling in the city.

"Iron-clawed monkeys, zero-order hellbeasts, social creatures, sharp claws, and agile movements."

"Demonic Scorpion Beast, a first-order prison beast, a social creature, a spear, bloodthirsty."

"Porcupine pigs, first-order prison beasts, solitary creatures, rare species with delicious meat, have a strong sense of self-preservation, can shoot hard thorns on the surface of the body to injure enemies in times of crisis, and have a mild temperament."

…………

This is the ability produced by Lin Han after breaking through in the afternoon, whenever he sees these unknown monsters, he will immediately appear in his mind the titles, levels and characteristics of these monsters, not only that, Lin Han found that his eyesight has also been greatly improved, although the whole city is now dim, but he can still clearly see the appearance of various monsters, which is almost equivalent to having the ability to see night vision, although such a change in himself makes him somewhat uneasy, but in any case, at this moment, That should be a good thing for him.

Of course, after the breakthrough, Lin Han's greatest improvement is his strength, compared with before, Lin Han feels that his strength has increased tenfold, which is why the two men in black can't make a move under him, you know, before the breakthrough, Lin Han has far surpassed ordinary people, according to his own estimates, before the breakthrough, he had at least three hundred catties of strength in one arm, if it is estimated with the strength of one hundred catties of an adult's single arm, Lin Han at that time would have three times the strength of a normal person, and after the breakthrough, Lin Han's strength increased tenfold again, that is to say, in just one afternoon, Lin Han actually had the power of thirty people, three thousand catties of huge strength, this is simply superhuman strength.

What's even more incredible is that at the moment when Lin Han broke through, such a piece of information suddenly appeared in his mind:

Name: Lin Han

Race: Human

Rank: Evolver Tier 1

Skill Evolution Points: 0

Ability Origin: Black Magic Vine

Origin Skill: Vine Control Technique, Skill Level: Level 1

Skill description: You can make the Yuan Force transform a black magic vine, and you have absolute control over the black magic vine, such as arm command, and the vine control technique is the original skill, which can be upgraded by itself with the improvement of the host's level, and cannot be actively upgraded.

With the appearance of this information, Lin Han instantly comprehended how to use the Yuan Force in his body to transform the Black Demon Vine, as if this was his innate instinct.

This rattan is extremely tough, Lin Han has tried, he used the fire axe to chop the rattan, until the axe handle is broken, and the rattan is not damaged at all, you must know that with Lin Han's current strength, wielding the fire axe with all his strength, he can definitely smash a big hole in the wall, which shows that the toughness of this rattan is strong.

In addition to these, there was another strange thing that happened to Lin Han when he broke through, thinking of this, Lin Han opened his mouth and said: "What are you, come out, now we can talk about it!" ”

As Lin Han's words fell, his forehead suddenly burst into purple light, and the brilliant purple brilliance soon gathered into a strange creature the size of a palm, this creature was like a mini kitten, extremely cute, the only difference was that there was a thin slit on his forehead, like a third eye, it looked quite weird, this creature was suspended in the air about a meter away from Lin Han, and said: "To be exact, I am not a flesh and blood life, but a magic weapon spirit between matter and energy, my name is Dudu, The book in your head is what I am. ”

"Books? You mean the wordless book that keeps flashing in my consciousness? Lin Han asked.

"That's right! That book was indeed called the Book of Heaven by later generations, and it had incredible power. Dudu replied.

"What's going on? A monster that suddenly appeared? Variations in my body? And you? ”

"That's a long story." The self-proclaimed little little man sighed and said: "Every other era, the demon army's destruction army will descend to every corner of the universe through the space-time rift, no one knows where they come from, only that they aim to kill living beings, and every time the demon comes to attack, it is a catastrophe for all living beings." ”

"You mean, the end of the world?" Lin Han asked.

"Yes, this is the end of the world for the creatures of Earth, but this is only the beginning of this catastrophe." Dudu said affirmatively.

When such an accident happened, Lin Han originally had some conjectures in his heart, but now after hearing Dudu's affirmative answer, he still felt a wave of unease and fear.

"Every time the demon invades, it is both an ordeal and an opportunity for the living beings, because according to the legend, the demons live in the core of the entire universe, so their life level is much higher than that of other races in the universe, and according to the law of conservation of energy and energy, other creatures that kill demon creatures will embark on the path of evolution, which is the reason for the mutation of your body." Dudu continued.

"You mean...... Evolve? Lin Han couldn't believe it.

"That's right! Isn't the change you are changing now a manifestation of evolution? Dudu asked rhetorically.

"Okay, what you're saying is too profound for me, can I simply understand that as long as I keep killing invading monsters, I can continue to evolve and gain more power?" Lin Han thought for a while and said.

"Exactly! Killing the Prison Beasts will absorb their life energy, and as the life energy continues to increase, all living beings can continue to break the shackles of life. "Dudu has a look on your face that you have finally come to your senses.

"Life Yuan Energy, does it mean Yuan Force?" Lin Han asked.

"Yuan force and life energy are two different things, Yuan Li is a kind of cosmic energy that living beings who have embarked on the road of evolution can be inherently able to control, after the Yuan Force is consumed, it can be restored by absorbing the Yuan Qi of heaven and earth, and the life Yuan Energy is the source of life of all living beings, and it is also the root of the evolution of all things."

Lin Han nodded thoughtfully.

"Evolution is far from being as simple as you think, and every step must follow the evolutionary rules of the universe. ”

"And the reason why I am called the treasure by later generations, hehe...... It is because of my existence that I can break one of the rules of evolution. Dudu said triumphantly.

Seeing Lin Han's seemingly understandable appearance, Dudu continued: "The evolution of human beings, every time they raise a level, they will comprehend a companion skill on the basis of their original ability, and every time they advance, the rules of heaven and earth will reward a chance to upgrade their skills. ”

"Is it a skill evolution point?" Lin Han asked.

"That's right, this is a very precious evolutionary attribute, as the level increases, there are more and more skills, and at this time, it is necessary for humans to choose the direction of evolution according to the skills they have comprehended."

"The existence of the Book of Heaven can just break such rules, the Book of Heaven depicts the eternal Book of Heaven and Craft, the Book of Heaven has the magical power to shield the rules of heaven and earth, as long as you absorb enough energy, you can open the Book of Heaven and Mind to increase your chances of skill improvement." He said in a sigh of relief.

"Does energy mean that?" Lin Han took out the milky white crystal from his pocket and asked.

"Yes, this is the zero-order element crystal, it is the lowest level of the Yuan Energy crystal nucleus, the Yuan Energy crystal nucleus is the purest life crystal in the universe, there are many wonderful uses, the most direct is that it can provide pure life energy for living beings, and then achieve the effect of healing injuries, and at the same time, it can also be used to restore Yuan power."

That's right, it was through Dudu's reminder in the private room that Lin Han learned about the magic of this crystal nucleus, and then he used Yuan Jing to treat Li Dong, Lou and Tang Chen, and these crystal nuclei were also found by Lin Han from the heads of the iron-clawed monkeys he killed under Dudu's prompting.

"In addition, Yuanjing has a more important role, that is, when human beings evolve to the limit of the zero order, they must rely on Yuanjing to obtain the power of the origin and truly embark on the path of evolution." Dudu continued.

"Yuanjing is divided into nine levels, which are distinguished by color, white, red, orange, yellow, green, cyan, blue, purple, and black, corresponding to the nine levels of demonic hellbeasts and humans."

"Nine ranks? Are you saying that if I keep evolving like this, I can break through nine times? Lin Han felt a little incredible, you must know that he is only a first-order now, and he can basically be divided into a non-human category, if he reaches the ninth order, how powerful it will be, Lin Han can't imagine.
