Aha, um, Wei Zi.

During a chemical research experiment, Jimmy and Sam were assigned to a project team and synthesized a tube of blue-purple reagent together.

The upper part is required to be blue and the lower part to be purple.

A week passed, and I only saw the blue in the test tube, but there was no progress in purple.

Three days have passed and the deadline is getting closer and closer. After staying up late for several days, when they were exhausted, Sam finalized the final version of the plan. He looked at Jimmy confidently. When they were in proportion, they fell asleep on the table.

Sam, in particular, began to snore in less than a minute.

A few hours later, Jimmy opened his sleepy eyes.

"Aha!" The present situation made him suddenly stand up.

Sam woke with a start, as if everything was expected, smiled and gave a "well" and fell down again.

But Jimmy was so excited that the table shook under the impact and the iron frame seemed unstable.

"well! ! ! "With Jimmy's cry and outstretched hands, the counter landed on Sam's arm.

"Well ..." Sam looked dreamily at the reagent spilled on his sleeve.
