章 473: Monster Siege

"Alright, Chief Engineer Wu!"

Xu Wanqing nodded her head lightly, and her face full of firm trust.

Returning to the system store, Wu Wu opened the research interface of Life First again and began to repair it without hesitation.

Time seemed to pass in his fingertips. Finally, after consuming a large number of points, the bug was fixed.

Then, he took the repaired Life First potion and carried out a round of rigorous tests.

Sure enough, with this fix, even those with special blood types could enjoy the youthful vitality brought by Life First.

The bug was quickly fixed just like that.

At this moment, the Heart of the Ocean had already been placed at the site of the shipwreck.

Wu Mo and the old chief dared not be careless at all. They had been paying attention to the feedback from the other side.
