Liao Fan entered the wormhole space this time, and there were two goals in total.

At present, the first goal has been basically achieved, and the next thing to do is to find the "wood element".

The so-called "wood element" is also a special energy source that is born after natural compression.

Different elements, the attributes presented are also different, according to the information of Liao Fan's previous life, there will be a total of five elements in this world: metal, wood, water, fire, and earth.

The elemental energy that befalls inside the medical school belongs to the "wood attribute".

Elemental energy is a rather special attribute carrier, which is different from the source crystal, and cannot directly help humans break through evolution, but it has a powerful attribute effect.

To put it simply, after refining the wood element, Liao Fan's body will also inherit a certain amount of wood attribute energy, and as a result, he will gain strong life ability.

Perhaps there will not be a significant increase in combat power, but as his vitality increases, his defense and recovery ability can be greatly improved, as long as he does not take mortal damage, he can recover more quickly.

Of course, elemental energy is quite rare, even rarer than high-grade source crystals, in the last days, there are too few people who can get away with refining elemental energy, and Liao Fan in the previous life has only heard of it, and has never personally experienced the benefits brought by the elements.

"If my memory is correct, there will definitely be wood elemental energy born here, as long as I get it, I will be able to completely complete the first stage of apocalyptic preparations."

Staring at the dense fog outside, Liao Fan's heart fluctuated, and his eyes kept flickering.

At this stage, the medical school has been completely swallowed by wormholes, and that special energy can be born in any corner, so he must hurry up and leave here to search.

Ten minutes later, Liao Fan retracted his gaze and looked at Liao Yun again.

At this time, Liao Yun still maintained the posture of sitting cross-legged on the ground, holding half of the source crystal tightly, and silently refining.

Her talent is not bad, although she is not at the top, but she is also a little stronger than Liao Fan, after more than ten minutes of refining and absorption, the source crystal in her hand is also shrinking at a speed visible to the naked eye.

And after absorbing so much energy, Liao Yun's body also began to have obvious energy fluctuations, the breath was becoming condensed little by little, and the originally delicate little face became more crystal clear, and a jade brilliance was condensed.

"I wonder what kind of abilities Xiao Yun will gain after completing her evolution?"

Liao Fan narrowed his gaze and looked at Liao Yun's cheek motionlessly, silently expecting her to change in the future.

At this time, Liao Yun, who had been closing her eyes to refine energy, also slowly opened her eyes, a flash of crystal bright color flashed in her eyes, becoming smart and clear, her face was even more surprised, and she couldn't wait,

"Brother, this kind of source crystal is really amazing, I can feel that my body has changed significantly, as if my body has become much lighter."

Liao Fan smiled, "This is just the beginning, after you completely complete your evolution, you will definitely feel the reborn change, but this half of the source crystal is not enough to make you a real ability, what level you can improve to depends on your own talent." ”

As soon as he finished speaking, Sun Mu on the side also opened his eyes, and a sharp feeling also flashed in his eyes, and the overall momentum became completely different from before.

Like Liao Yun, after absorbing half of the source crystal, Sun Mu's breath also changed greatly, not only did his breathing become calm, but even his muscles became a lot stronger, and he could clearly capture that there was an unprecedented heat flowing in his body.

He simply threw a few punches, his fists whirring with the wind, looking dull and powerful, and his strength had increased several times.

Liao Fan said, "Yes, I have always been very accurate in looking at people, your talent is much stronger than ordinary people, according to this momentum, even if you can't get the further blessing of Yuan Jing, it is only a matter of time before you become an alien." ”

"It's a pity that there is only half a source crystal, and my current ability is still far worse than yours."

After starting the evolution, Sun Mu's perception ability has also been greatly improved, and he can naturally sense the huge gap between himself and Liao Fan more clearly.

He moved his limbs a few times, and then got up from the ground, feeling the heat flowing through his body, but there was a slight disappointment in his eyes.

"Hehe, you can't become a big fat man in one bite, if you want to become a stranger like me, you still have a long way to go, but compared to those ordinary people, you are already very powerful."

Liao Fan understood Sun Mu's thoughts, and immediately smiled, and was about to speak, but heard a large number of roars from the dense fog again, mixed with a lot of panicked footsteps.

"Someone is coming, and there are quite a few."

Sun Mu's perception ability had been greatly strengthened, and he immediately caught the strangeness coming from the dense fog, and hurriedly turned his gaze and hurriedly looked at the glass window.

Outside the library, a large amount of dense fog was still rolling and condensing, affecting the sight of the three of them.

However, through their extraordinary perception ability, the three of them still caught a large number of people on the run, and the direction of their escape happened to be towards the library.

"It's a lot!"

Liao Fan's perception ability was better than Sun Mu's, and he also perceived more content, only to see that in the depths of the dense fog, at least twenty or thirty shaking figures appeared, these people were speeding away, as if they were being pursued by some kind of terrifying creature, everyone was in a hurry, and their expressions were panicked.

But Liao Fan didn't mean to take care of it, he still shook his head and said, "Don't worry about the people outside, you continue to stay here to refine the source crystal, and you must not go out without my instructions." ”

Sun Mu said, "But these people are clearly still coming for us, even if we ignore them, I'm afraid we can't avoid them." ”

Liao Yun also got up and said, "Yes, looking at these people looking panicked, there must be monsters chasing them behind, why don't we call the people outside in and hide together?" ”

"Have you forgotten what I just said? Now is not the time to be heroic. ”

Liao Fan's eyes were cold, and he said to his sister, "You have indeed started to evolve now, but it is still too early to become an alien, with your ability, you may not even be able to protect yourself, and you are not qualified to rescue others." ”

"......"

Liao Yun opened her mouth and was about to refute two sentences, but she heard Sun Mu's voice become excited,

"Don't argue yet, look, what's that?"

Both of them were stunned for a moment, and they both turned their eyes to the window again, and then they saw some strange-looking creatures popping out of the thick fog.

The size of this creature is not large, only the size of two palms of an adult, the epidermis is dark blue, the body is oval, the lower limbs are slender, with a conical tail, and the flat body looks more like a moving bark, but there are many feet and limbs under the abdominal cavity, supporting the dry and rough body to crawl quickly, fitting with the surface of the ground, making a "rustling" grinding sound.
