Chapter 62

A thick look of surprise flashed in the old man's eyes, and even with his experience and city, he was shocked by Xu Zi'an's words.

He asked incredulously: "You... are you just preparing to take the college entrance exam now?"

Others behind the old man, one counts as one.

Hearing Xu Zi'an's words, one by one they couldn't help but open their mouths wide, dumbfounded.

After receiving Xu Zi'an's affirmative reply again.

The old man suddenly took a deep breath, the smile on his face converged, and he said with an extremely solemn expression: "Young man, let's get to know each other, my name is Xia Dongliu, may I ask the young man's name!"

"Xia Dongliu? Are you the Xia Dongliu, the Xia Lao who compiled the masterpiece 'Several Differences and Commonalities of Starship Evolution'?"

Hearing the old man's self-introduction, Xu Zi'an asked with surprise.

A smile appeared on Xia Dongliu's face: "Oh? Has the young man read my book?"

Xu Zi'an nodded repeatedly: "Read it, read it! Read it no less than twenty times! It's just that there are a few places I haven't understood yet...

Ah, right, my name is Xu Zi'an, Xu as in 'Yan Wu', Zi'an as in 'wishing the child peace'!"

Xia Dongliu became interested: "Where don't you understand, come and tell me!"

"It's just that in the work, it is mentioned that the generation of energy shields requires the addition of flammable and explosive materials such as sodium nitrate."

Xu Zi'an immediately stated his confusion: "But sodium nitrate will explode when heated or subjected to attack or impact.

Once it explodes, won't it also cause a certain energy loss to the energy shield itself?

So I want to ask Xia Lao, what is the main intention of adding materials such as sodium nitrate to the energy shield!"
