On the way, Huang Yuan also knew that in addition to the exquisite course of textbooks, there was also another topic added in this study class: fireflies.

Fireflies are just a kind of idle insects, but since three months ago, these fireflies in Tianma Mountain have magically gathered together at night, and the fluorescent glow that emits can shine around as if it were day.

The special fluorescent effect makes the place where these fireflies gather like a fairy mirror, which also attracts many people in Lanzhou City to set up tents on Tianma at night to enjoy this beautiful scenery.

After the car stopped, all the students of the 03 class of the biology department got off the school bus with great interest, and the extracurricular study class was an alternative field trip for them.

Huang Yuan stopped the car, turned his head to Wu Xi and said, "Xiaoxi, you get out of the car first, I'll go to the parking lot to park." ”

Hearing Xiao Xi's intimate title, Wu Xi blushed slightly and said embarrassedly: "Huang Yuan, you give me your ID card, those fireflies won't come out until the evening, so we rent a tent at the foot of the mountain and set up a tent on the mountain at night." ”

Huang Yuan nodded and handed his ID card to Wu Xi.

But when Wu Xi took the ID card, there was an incredible expression in his eyes, because of the date on the ID card, Huang Yuan was a few months younger than her.

Thinking of Huang Yuan accepting her as a godsister, her pretty face turned uncontrollably red, she was even older than Huang Yuan.

Huang Yuan looked at Wu Xi suspiciously: "What's wrong?"

"I didn't ...... It's nothing...... I went to rent a tent. Wu Xi hurriedly put away his ID card, and then opened the car door in a panic and got out of the car.

The teacher who led the extracurricular study class was very knowledgeable, at least after entering the mountain, he could also organize these students to carry out the study class normally, Huang Yuan was originally at Changhai University, and almost half of this kind of study class was done by themselves.

As time passed, Class 03's study class was completed, and when night fell, more and more fireflies began to appear around.

The students had already set up their tents, and they had also noticed a lot of people who had come to enjoy the night view of the fireflies, many of whom were already catching fireflies with nets and putting them in transparent jars.

When Huang Yuan helped Wu Xi set up the tent, he looked up in surprise, and the mysterious tattoo on his abdomen reacted again, and it was among the fireflies that caused the mysterious tattoo reaction.

Fireflies gather more and more, the fluorescent flashes around are getting brighter and brighter, those fireflies flying in the air converge as if it is like a galaxy, in the dark night, the forest illuminated by fluorescent seems to be like a psychedelic forest.

"Huang Yuan, it's so beautiful. Wu Xi excitedly took out his mobile phone to take pictures of the group of fireflies.

"It's fireflies in groups. The teacher who led the team looked at this scene in surprise: "But this kind of group activity must have a leader, just like the queen of bees and the queen of ants, but the average lifespan of fireflies is only 5 days, and it is impossible to produce a leader." ”

Huang Yuan's eyes lit up when he heard the words of the leading teacher, he was sure that the reaction that caused the tattoo was this firefly leader, under normal circumstances, the firefly only had a lifespan of 5 days, but the firefly that could cause the mysterious tattoo reaction was definitely not an ordinary firefly.

Huang Yuan did not hesitate, and walked directly to a tall boy who was holding a net bag and was about to catch fireflies, and snatched the net bag from the boy's hand.

"...... Which bastard robbed me......" The boy was suddenly robbed of his tools and was about to get angry, but when he turned his head and saw that it was Huang Yuan, his anger was immediately put away, and the words behind him immediately swallowed back his stomach, and he smiled awkwardly: "Huang ...... Huang Dashao, I didn't mean that......"

Huang Yuan ignored the tall student and ran towards the firefly that caused the mysterious tattoo reaction with the net bag.

After rushing down the hill, Huang Yuan arrived at the place where the fireflies gathered the most, and according to the guidance of the mysterious tattoo, he saw the brightest one among the countless fireflies, and it seemed to be much larger than the other fireflies.

This should be the Firefly Boss.

But before Huang Yuan could make a move, several men and women with nets rushed over to disturb these fireflies, causing the firefly leader to fly away with the group of fireflies in a panic.

Huang Yuan hurriedly followed, and found that the firefly leader had stopped on a river, and that kind of height ordinary people couldn't catch it at all.

Luckily, there is also a wooden bridge over the river.

Huang Yuan saw that there was no one around, so he sprinted directly on the shore, and the whole person stood up high, rushed into the group of fireflies, and then hurriedly waved the net pocket and covered the firefly leader into the net pocket.

Bang!~

Huang Yuan's body drew a parabola in the air, landed steadily on the wooden bridge, and then restrained the hurried net pocket, the firefly leader was flying in a panic, however, the light emitted by this firefly seemed to be a little different from that of ordinary fireflies, it was not fluorescent, but a very pure white light, giving people a feeling of purity all the time.

Feeling that the mysterious tattoo on his abdomen reacted more violently, Huang Yuan couldn't wait to reach out and pinch the firefly leader to death, and then pulled up his clothes, and the mysterious tattoo immediately shot out a scarlet light and shrouded the firefly.

Moments later, the firefly leader turned into dots of light and returned to the mysterious tattoo along with the scarlet light.

Then, a tingling sensation came, the cells in the body were dividing rapidly, and through the mysterious tattoo, he could actually sense that the cells that had divided out actually emitted a special light.

Eventually, the pain disappeared and the transformation was complete.

Huang Yuan hurriedly urged the new ability, and as soon as his mind moved, he felt that the cells in his body that were splitting out and emitting light moved rapidly, and the energy in the dantian seemed to be pulled into these cells, and with the consumption of the dantian energy, the light emitted by these cells suddenly became stronger, and it actually converged towards Huang Yuan's palm.

This is a very wonderful feeling, Huang Yuan can't see the movement of cells in his body, but he can sense it through the mysterious tattoo. On his outstretched palm, a small ball of pure white light slowly condensed.

With a wave of Huang Yuan's palm, the ball of light smashed on the guardrail of the wooden bridge, but except for the explosion of a ray of light, it did not cause any damage to the guardrail of the wooden bridge.

Huang Yuan condensed a ball of light again, but he didn't find any attack power after studying for a long time, which made him a little disappointed, this is the real chicken rib ability, is this light useless except lighting?

Huang Yuan...... Your palms ......" Wu Xi's surprised voice sounded behind Huang Yuan.

Huang Yuan hurriedly dispersed the fluorescence in his palm: "It's just a magic trick. ”

"But...... But I just saw you jump so high that you jumped right over there. Wu Xi whispered, "Do you have special functions?"

Huang Yuan sighed, he didn't expect Wu Xi to follow, so he simply admitted: "Do you think I'm a freak now?"

"I didn't ...... No, I'll keep it a secret for you. Wu Xi hurriedly shook it: "Can you let me take another look at the light cluster just now?"

"I'll go back to the tent and show you. Huang Yuan smiled and touched Wu Xi's head.

However, Wu Xi's reaction made him feel strange, the first time he saw this kind of inhuman power, he would be a little afraid, right? Why did she seem to be very calm?

"It's a human head. Wu Xi muttered.

Just as the two of them walked towards the shore, Huang Yuan's brows suddenly wrinkled, and the mysterious tattoo on his abdomen reacted again at this time, and following the guidance of the tattoo, it was a big man who rushed here quickly to cause the tattoo reaction.

The big man was full of indifference, holding a huge stone, a stone of that size would be difficult for ordinary people to walk with their hands up, but this big man was holding the boulder and rushing fast.

The moment he saw this big man, he instantly remembered the Throat Cutting Demon.

Huang Yuan felt the murderous aura on the big man's body, and the ferocity in his eyes was obviously a murderous person, and it was obviously not good.

"Xiaoxi, let's go. Huang Yuan hurriedly turned his head and took Wu Xi's little hand.

"Be careful. Wu Xi exclaimed.

Huang Yuan turned around, only to see that the boulder in the hand of the big man had already smashed towards them, and it reached the top of his head in an instant, Huang Yuan subconsciously wanted to jump back, but he dodged it, and Wu Xi behind him would definitely be hit by the boulder.

This was obviously carefully calculated by the big man, and it was extremely accurate, not only using the narrow space of the wooden bridge, but also using Wu Xi, at this time he wanted to pull Wu Xi along, and he could be directly hit by a boulder in his back, which would be even worse.

"Damn. Huang Yuan shouted angrily, and had to force himself to face the boulder, and at the moment when the boulder fell, he slammed it with a punch.

Bang!~

Huang Yuan's punch instantly smashed on the boulder, and the huge force rushed out, blocking the forward rush of the stone, but when the huge stone was smashed out, the force of the forward rush was definitely several times stronger than its own weight, although Huang Yuan's blocked the boulder, but the fist was also instantaneous blood, and he was shocked and spit out a mouthful of blood.

No matter how terrifying his strength is now, no matter how strong his jumping ability is, his physical strength is still very weak.

The boulder fell on the wooden bridge, causing the simple wooden bridge to shake for a while, and Huang Yuan and Wu Xi suddenly stood unsteadily.

Dahan was stunned for a moment when he saw that the boulder had no effect, but the next moment, Dahan rushed straight towards the wooden bridge and slammed his fist on the wooden bridge.

Bang!~

The simple wooden bridge collapsed violently under the big man's punch.

"Ah......" Wu Xi screamed, and Huang Yuan and Huang Yuan all fell into the river, as soon as they reached the water, Wu Xi panicked and exclaimed: "Ah...... I can't swim. ”

Huang Yuan hurriedly hugged her: "Don't move." ”

Wu Xi subconsciously grabbed Wu Yuan's neck with both hands, and after stabilizing her body, Wu Xi felt the bodies of the two sticking together, even in the water, she couldn't help but blush, because the clothes were soaked, and the thin cloth stuck to her body, she and Huang Yuan seemed to be naked and stuck together.

"Give me death. Dahan's voice sounded, and he saw that Dahan had an extra piece of crosswood of a wooden bridge in his hand, and smashed it down on the two of them.
