A few afternoons later, there were only two people in the laboratory.
Gu Yue stood in front of the experimental table, with a beaker in front of him.
The beaker contained a freshly prepared solution, which was transparent and looked no different from plain water. She added another drop into it and let it sit.
Changes occur at the moment of cooling.
The transparent liquid suddenly surged, and golden crystals precipitated from the solution, like countless fine golden snowflakes falling slowly in the test tube. Layers of sediment accumulated at the bottom of the tube, reflecting bright light under the cold white light of the laboratory.
Gold Rain.
She knew the chemical formula by heart, but when she saw it with her own eyes, she remained silent for a few seconds.
Xiao Mu stood next to her, put down the Soul Tool part that was being calibrated in his hand, glanced at the beaker, and took out a few things from the cabinet under the experimental table.
"That doesn't work, this experiment is more fun."
He poured a layer of fine sand into the porcelain plate, soaked it with alcohol, and then made a small pit on the top of the sand pile. Mix the powdered sugar and baking soda and pour it into the pit.
Light the match and throw it up.
The chemical reaction starts quickly.
A wisp of green smoke first appeared from the top of the sand pile, and then a black-gray substance slowly grew out of the flames, like a snake emerging from the ground, twisting and expanding, stretching longer and longer, with a burnt caramel smell.
Gu Yue stared at the charcoal snake that was still squirming slightly for a long time.
"... This is called Pharaoh's Serpent." Xiao Mu threw the matchbox back on the table, "It's fun."
Gu Yue said speechlessly, "Is this fun? Are you sure you are not here to disgust me?"
"No!" Xiao Mu smiled lightly.
Gu Yue pushed the beaker forward, Gold Rain's crystals were still quietly refracting golden light at the bottom of the cup, bright, clean, like solidified starlight. Then she pointed at the charred carbon snake in the porcelain plate, like some indescribable thing that had just crawled out of the crater.
"My side is golden." Gu Yue said.
"Hmm."
"You have a burnt snake over there."
"Pharaoh's Serpent." Xiao Mu corrected.
"It doesn't look good." Gu Yue's voice was still calm, "It looks disgusting."
Xiao Mu smiled and quickly packed up the laboratory.
The two people walked out of the laboratory one after another. The air in the corridor was much cooler than that in the laboratory. The sycamore trees outside the window were rustling in the wind, and the sunlight leaked from the leaves and sprinkled gold on the ground.
Xu Xiaoyan is standing at the corner of the corridor.
When she saw Xiao Mu coming out, her eyes lit up, then she ran over in three steps and two steps at a time, opened her arms and jumped directly into his arms. The skirt of her school uniform rose and fell during the movement, and her whole figure was like a small cannonball, which made Xiao Mu take half a step back.
"Xiao Mu, you finally came out."
Xiao Mu steadied his steps and caught her shoulder with one hand. The other hand was still in his pocket before he could take it out.
"Why are you in such a hurry? You're still hitting me!"
"I just want to hit him." Xu Xiaoyan buried his face in his chest and rubbed it, his voice was muffled, "Why did you just come out of the laboratory?"
"I did an experiment."
Xu Xiaoyan raised her head and sniffed his collar, then looked over his shoulder and saw Gu Yue following behind. She blinked. "Sister Gu Yue, did he do something weird again?"
Gu Yue walked past her without stopping, and only left one sentence. "This guy gave me a show of chemical shit! It disgusted me."
"Chemical shit--hahahahahaha!" Xu Xiaoyan laughed so hard that he bent down and hung on Xiao Mu's arm to keep him from sliding down, "Sister Gu Yue, you describe this--"
Gu Yue said calmly, "Seek truth from facts."
Xiao Mu took his arm out of Xu Xiaoyan's hand and helped her. "Stand still."
"No, let me laugh a little longer - chemical shit, I want to write it down -"
There was a rush of footsteps from the other end of the corridor, approaching from far away, and the rhythm was as brisk as a sparrow jumping on the steps.
Na'er rushed out from the corner, her ponytail swinging back and forth behind her head, and she almost couldn't stop the car and hit the wall. She supported the wall with one hand to steady her body, and pointed at Xiao Mu with the other hand, and took two breaths.
"Brother! The dean asked you to come over."
Xiao Mu was adjusting the collar that was crooked by Xu Xiaoyan, and paused for a moment. "Us?"
"You, sister Gu Yue, Xu Xiaoyan, and me." Na'er counted them on his hands, "Four of us, go to the dean's office immediately."
"What's the matter?" Xiao Mu asked.
"I don't know." Na'er shook his head, "But Long Chen and Yuanen Yehui are going too."
Xiao Mu and Xu Xiaoyan looked at each other. Long Chen, Xu Yucheng and Yuanen Yehui, plus the four of them, there were seven people in total.
This combination reminded him of something.
The door to the dean's office was ajar.
Xiao Mu knocked twice, and Mu Hongchen's voice came from inside. "Come in."
When I opened the door, there were already several people standing in the office.
Na'er poked his head out from behind Xiao Mu, scanned the people present, and whispered in a low voice, "This battle is going to be a long journey."
Mu Hongchen is sitting behind the desk, with his hands folded on the table and a file with a red header spread out in front of him.
She waited until the last person came in and closed the door before she said, "Everyone is here."
Mu Hongchen pushed the file with the red header forward and scanned the faces of the seven people present in turn.
"Star Luo Royal Academy has officially sent an invitation letter, asking you to go to the Star Luo Continent for exchange and study. It will last for one year."
"After the last exchange competition, someone asked you to come over by name."
The office was quiet for two seconds.
Na'er was the first to speak out, "Star Luo Continent? Doesn't that mean we have to sit on a boat for a long time?"
"Two months by sea." Mu Hongchen said, "The college will arrange the itinerary, and Star Luo Empire's food, accommodation and transportation are all covered. In addition, I will send a Super Douluo to accompany you, so you don't have to worry about safety on the road."
Long Chen turned around from the window and raised his eyebrows. "One year?"
"One year." Mu Hongchen nodded, "Going to other people's mainland for exchanges is just a slap in the face. You won't suffer any loss if you go."
Yuanen Yehui put the file in his hand on the table, raised his eyes and asked, "Just the seven of us?"
Mu Hongchen looked at the list. "Xiao Mu, Gu Yue, Na'er, Xu Xiaoyan, Long Chen, Yuanen Yehui, Xu Yucheng. Seven of you."
Xu Yucheng raised his head from the bookshelf, closed the old book, and said lightly, "I have no problem."
Xiao Mu remained silent, leaning on the armrest of the sofa, tapping the edge of the leather armrest with his fingers unconsciously. Mu Hongchen looked at him. "What about you?"
"It's okay to go." Xiao Mu said, "One year is not a short time. What should I do with the laboratory project?"
"Don't worry, someone will keep an eye on it for you." Mu Hongchen was already prepared.
Xiao Mu thought for a while and nodded.
"If you have no objection, we will leave in three months."
