After looking for a long time nearby, Zhou Yunfeng still didn't find anything at all, so he rode his bicycle to a farther location to check, but unfortunately he didn't get anything, and he had a hunch in his heart that he was going to return empty-handed today.

"Well, what's the sound?" Just as he was concentrating on finding the crystal, there was a sudden movement not far away.

In an unusually quiet environment, Zhou Yunfeng could hear the slightest movement clearly, and as soon as he heard the movement, he subconsciously looked in the direction where the sound came from.

As soon as his head turned around, he didn't see any figure, he was a little nervous, and he was not sure what the situation was, the saber tied to his thigh was pulled out by him, and he held it tightly in his right hand, and with a flashlight in his left hand, he took a small step, and gradually approached the direction of the corner.

At this moment he was very nervous, approaching very slowly, walking as gently as possible, without making the slightest sound. After a while, I finally came to the corner, and in front of me were several garbage bins, from which the movement just came out.

When he was only about ten meters away from the garbage bin, there was a sudden movement from one of the garbage bins, which frightened his heart several times, and then there was a squeak, and he immediately guessed what it was.

"It turned out to be just a mouse, it really scared me just now!" After guessing that it was a mouse, Zhou Yunfeng let out a long sigh of relief.

And just as he was relaxing a little, a black shadow suddenly strung out of the garbage can, causing Zhou Yunfeng to take several steps back in an instant.

When he saw the figure coming out of the garbage can, Zhou Yunfeng's eyes were round, and his face was full of shock.

What appeared in sight was indeed a mouse, yes, but it was very wrong.

The rat was the size of an adult domestic cat, and it was biting on the frozen waste food in its mouth, Zhou Yunfeng swore that this was the first time he had seen such a big mouse, it was ridiculously big, and it stands to reason that the mouse could not grow so big.

A few seconds after the rat came out of the garbage can, another one came out of it, and it was about the same size, and what was even more surprising was that the two big rats were not afraid at all when they saw him as a living person, and seemed to be looking at Zhou Yunfeng's appearance.

Zhou Yunfeng has never been afraid of rats, but after seeing these two oversized mice today, he couldn't help but feel a trace of fear in his heart, and began to slowly retreat, trying to distance himself from them.

Zhou Yunfeng gradually retreated, away from the two mice, and they didn't follow, just glanced at him a few times, and then ran away without a trace.

"It should be related to the radiation of the blue full moon, since the radiation is beneficial to humans, it should be the same for other creatures, this makes sense, how can those two mice be so big......"

After the mice disappeared, Zhou Yunfeng recalled the radiation information in the diary, the reason why the two mice became so big was inseparable from the radiation.

After encountering the episode of the big mouse, Zhou Yunfeng became a little more cautious than before.

Before he knew it, another two hours had passed, and Zhou Yunfeng felt that there was no drama today, and was about to leave for his residence, but at this moment, the flashlight beam shone on a reflective object, which immediately attracted his attention.

With a flashlight, he slowly walked towards the reflector, and when he got close to a certain distance, Zhou Yunfeng's eyes suddenly lit up, and the reflective object on the ground was a crystal in the shape of an octahedron.

Excited, he quickened his pace, reached out and picked up the small crystal on the ground, put it on his hand to check it for a few moments, then put away his things, and quickly evacuated the place and returned to his residence.

…………

When he returned to his residence, Zhou Yunfeng was shivering with cold, turned on the heater in the room as soon as possible, stood on the edge of the heating outlet and blew for a while, before he felt a lot more comfortable, and his body temperature returned to normal levels.

This time he went out and stayed outside for nearly seven hours, and Zhou Yunfeng roughly understood the limit of the time he could stay outside from the experience of this outing.

Taking out the newly obtained crystal and looking at it, Zhou Yunfeng soon found that the degree of discoloration of this crystal was higher than the one he had obtained before, and after thinking about it carefully, he guessed the reason.

This newly obtained crystal has been exposed to the light of the moon, while the previous one has been left indoors, and the diary mentions that the radiation carried by the moonlight, although it can also penetrate the building, will be weakened.

From this, Zhou Yunfeng can judge that when directly exposed to moonlight, the crystal will absorb the radiation energy faster, and the color will change faster.

Zhou Yunfeng thought about it and chose to expose the crystal to the direct irradiation of the moon, in order to maximize the speed at which the crystal absorbed radiation.

It wasn't until February 18 that the first crystal finally turned completely blue just a little bit.

Zhou Yunfeng held this crystal in his hand, and ran to the rooftop alone to wait.

After waiting for about a few minutes, the crystal finally turned completely blue, and from this moment on, Zhou Yunfeng's eyes never left the crystal in his hand for a moment, and his heart was full of anticipation.

After about a dozen seconds, the crystal in his hand gradually emitted a faint blue light, which lasted for about a minute.

It didn't take long for the faint blue light to dissipate, and the discolored crystals faded at a speed visible to the naked eye, returning to a transparent state after only a few seconds, just like at the beginning.

"It looks like the absorbed radiation energy has been consumed, and we have to reabsorb it again to make the change just now!" After seeing this brief change, Zhou Yunfeng said to himself.

As soon as the crystal change was over, Zhou Yunfeng left the rooftop and went back indoors, picking up a heavy object to test his strength, and when he picked up the heavy object, he felt a little lighter than usual.

It's not obvious, but it's a little lighter, which means that the strength is a little bit stronger than before, and when he got up this morning, he worked out with the same weights, so there is no mistake about it, the strength has indeed increased.

"Sure enough, it's the same as the diary!" Determining that the crystal can really bring benefits to himself, Zhou Yunfeng is very excited, and he can't wait to get a few more, but unfortunately the distance taken by the monitor is limited, and there is no way to determine the location where the other flashes fell.

Zhou Yunfeng checked the information, the strongest strong man in the world can reach about five times that of ordinary people in terms of strength, and after this period of training, and under the strengthening effect of radiation, his strength is roughly twice that of ordinary people.

This kind of improvement is quite amazing, it is impossible to achieve this effect by exercising alone, Zhou Yunfeng can be sure that under the effect of radiation, in the near future, various previous world records will definitely be broken.

Under the effect of radiation, Zhou Yunfeng has improved not only his strength, but also his comprehensive qualities such as sensitivity and reaction speed have been improved to a certain extent, which is far from just strength.

For example, if you compare a strong man who is five times stronger than an ordinary person and a person whose comprehensive quality is five times that of an ordinary person, the difference is not half a star, and there is no comparison between the two at all.

In terms of strength, the two may be about the same, but in terms of explosion and combat ability, they are completely different things, and Hercules will only be crushed unilaterally.

Not to mention that the overall quality is five times that of ordinary people, even if it is only more than three times, Hercules is unlikely to be an opponent, this is the gap, and as the multiple increases, this gap will get bigger and bigger.

In the past, it was basically impossible for the comprehensive quality to reach five times that of ordinary people, which was out of the limit of the human species, and if it could reach ten times, it could already be regarded as a new species.

Zhou Yunfeng can be sure that human beings are indeed evolving, but what about other creatures, and it is unlikely that human beings will stand at the top of all species as before in the future, and will inevitably face severe challenges.

Thinking of this, Zhou Yunfeng's eyes were a little complicated, and he gradually fell into contemplation.

…………

Three days later, the cover of the notebook also turned completely light blue, but after turning light blue, the cover did not change in any way, and remained in its current state, and the rest of the notebook did not appear abnormal.

Zhou Yunfeng originally suspected that the notebook would also have a similar effect to crystals, but now it seems that this is not the case, and after thinking hard and meditating to no avail, he gave up continuing to ponder.

Fast forward to the end of March, almost two months later, and everything was exactly as described in the diary on page 4 of the notebook, with radiation information published on the television news, but not mentioned by the crystals.

Although it has not been announced, Zhou Yunfeng can be sure that the official has secretly sent people to collect this crystal.

Since March, the temperature has been rising, and today, the temperature has returned to about 10 degrees Celsius, and more people are going out day by day.

But Zhou Yunfeng always felt very uneasy in his heart, but he couldn't say why, he really wanted to see the content of the fifth page of the notebook, but he never got his wish, almost two months, and the new diary still did not appear.

…………

On the last day of March, just before the first day of April, the blue moon was obscured by a dark cloud, which quickly dispersed, similar to the situation on the first day of January.

However, after the clouds cleared this time, the moon disappeared and was replaced by the sun, which had disappeared for three months, and the change was very sudden, and the sun appeared quietly.

After the sun appeared, the official news did not announce it for the first time, and the earth has returned to normal since then, Zhou Yunfeng felt very strange.

However, he soon learned why, and the next day's news mentioned that the other side of the earth was also illuminated by the sun, and he had the illusion that this sun had changed from the previous blue moon.

Since three months ago, all space equipment has not been able to leave the atmosphere for unknown reasons, and for now, the situation on Earth has not returned to normal.

The sun begins the day after it appears, and the temperature gradually rises over time, but the color is not normal, gradually changing to purple, and by the middle of April, the temperature has exceeded 30 degrees Celsius.

"Damn! Contrary to the previous situation of the Blue Moon! One low temperature, one high temperature, this climate is completely chaotic! At this point, Zhou Yunfeng was skeptical that the temperature would rise to a peak within a month, the exact opposite of the previous three months.

It's not just the temperature and the sun that have changed, Zhou Yunfeng also found a new phenomenon from his notebook, the back actually began to change color like the front, from black to light purple.

"The blue full moon is the cover, and the purple sun is the back! Corresponding to the anomaly, what secrets does this notebook hide? Looking at the notebook, Zhou Yunfeng fell into deep thought.

The various changes in the notebook made Zhou Yunfeng feel more and more mysterious, as if there was a veil of mystery shrouded in it, and he wanted to know what the origin of the notebook was, and what was the relationship between it and the abnormal phenomena that are happening now......

Just as his mind was full of doubts, suddenly a cry for help came into the house, which seemed to be from the corridor outside the door.

As soon as he heard this voice, Zhou Yunfeng didn't immediately open the door to check, but first looked at the monitor installed in the corridor. In the surveillance footage, a man and a woman clashed in the corridor, but it was the man who made the cry for help.

The two scuffled on the ground, and it was the man who was beaten, and the woman's back was facing the direction of the monitor camera, and her cloak looked like a madman, and she kept smashing the man with her fists, and even faintly saw that her hands were stained with blood.

Seeing this, Zhou Yunfeng was a little surprised, the little couple seemed to have quarreled a little seriously, so he stood up, walked over and opened the door, and was ready to step forward to dissuade him.

He wasn't the only one who heard the cries for help, people on other floors also heard them.

The two people who scuffled were both residents on this floor, and they happened to be next door to Zhou Yunfeng, and he was the first to come out to check the situation.

"Hey, miss, if you have something to say, you better stop quickly, if you continue to fight, you will die." As soon as Zhou Yunfeng came out, he shouted loudly to the woman.

The woman was beating the boy, and after hearing Zhou Yunfeng's shout, her right hand, which was about to be smashed down, suddenly stopped, and turned her head to look at him suddenly.

When the woman turned her head, Zhou Yunfeng's heart beat violently, the woman's eyes were red, and red and purple veins appeared on her face, which looked particularly penetrating.

Seeing such a face, Zhou Yunfeng was immediately frightened, subconsciously took a step back, and swallowed his saliva.

The woman with the disheveled hair suddenly stood up, did not continue to beat the man under her, and rushed towards Zhou Yunfeng without saying a word.

Although he was taken aback, Zhou Yunfeng reacted very quickly, and when the woman was about to make a move on him, he immediately grabbed her wrist with his hand.

"How can a woman have so much strength!" The wrist was grabbed, and the woman struggled to break free, looking crazy, she only wanted to do something to Zhou Yunfeng, and her strength was very strong.

Zhou Yunfeng obviously felt that her strength was only a little smaller than his own, and he was very surprised, he estimated that his current strength was close to more than twice that of ordinary people, and he actually felt struggling.

"Hey, Miss, what are you doing, say something!" Zhou Yunfeng's face turned red, he grabbed her wrist and didn't dare to relax, and at the same time opened his mouth to ask.

In the face of Zhou Yunfeng's questioning, the woman ignored it, as if she hadn't heard a word, and only thought about attacking him.

The next moment, the woman suddenly kicked sideways and kicked Zhou Yunfeng in the stomach, kicking him a few meters away at once.

was kicked hard, and after getting up, Zhou Yunfeng covered his stomach with one hand, half-knelt on the ground, with a painful expression, and his mouth opened into an O-shape.

After kicking Zhou Yunfeng away, the woman rushed over again without reluctance.

Zhou Yunfeng felt a lot of pain in his stomach, but he also reacted in time, and directly stretched out his leg and swept over, and the woman was immediately tripped and fell to the ground, and then he reflexively pressed it to the ground, and his eyes were quick and his backhand clasped her two hands......
