A Slap in the Face!

Li Xuekai was stunned. It was late at night, but the laboratory was bustling.

After the theory was completed, everyone's mood had been very low because everyone knew that the light source machine itself could not be completed.

If they were this happy now, could it be…

He suddenly lifted his head and looked at the laboratory in disbelief. He quickened his pace until he was running.

Just as he reached the entrance, he saw that the people who had not left the laboratory were all hugging each other. Some were crying tears of joy while others were hugging each other. They were so touched that they were stomping their feet like children.

Only Xue Xi stood by the side. She seemed to have been certain since long ago that the light source machine would be a success, so she was not excited at this moment. However, there was a hint of gentleness on her cold face and she was no longer looking at everything indifferently.
