"The theoretical limit of the watertight compartment of our ship is fifteen tons!"

As the words fell, the drone's camera immediately pointed at a piece of draft paper.

It is densely filled with various formulas and numerical symbols.

Hearing the words, the students in the first class also looked up and watched immediately.

Then they fell into deep contemplation.

They know all the things on the screen, but when they are combined, they don’t know what they mean at all.

Let’s look at the student in Class 9 again, and was explaining to a strong man with great enthusiasm:

"Brother Chen, look, the total weight of the materials used in our design drawings is 112 tons. After that, some other things can be added, and the weight can reach about 120 tons."

“Then according to the formula, we can calculate the displacement.”

“Based on the displacement.”

Listening to the other party's joking voice, all the students in the class were confused, as if they were listening to a heavenly book.

A face full of surprise.

Is the other party really the same class 9 student from the past?

These are really what my teacher said about self-deprecating guys?!!!

The next moment, they all looked at the class teacher.

The meaning is very clear.

Are you sure the other party has really not made any progress?!

Why don't we understand what they are saying now?

The head teacher of Class 1 turned dark and felt a little annoyed.

Why can’t the students in this class nine cooperate with them?
Chapter completed!
