Chapter 518

"Yay! It worked!"

Sudden cheers erupted in the research lab!

The successful trial of the plague vaccine indicated that the greatest threat brought by the Black Dragon Empire's Undead Legion to the White Dragon Empire had been removed!

"Don't be too happy, this is just the first successful attempt. We still have to conduct multiple cross-comparison experiments, and we need to test it on primates," Mrs. Nor said with a smile on her face. Clearly, she was joyful too, but as the person in charge, she naturally understood their excitement!

"Told you so!" a scientist whispered to Mrs. Nor.

"Hmm, you're just lucky. Be prepared to kneel and scrub the washing board when we get home," Mrs. Nor grumbled.

"Even if I need to scrub the washing board, future chores like cooking for half a year will be yours!"

Turns out, this old scientist was Mrs. Nor's husband!
