Chapter 91: Those with money contribute money, those with strength contribute effort

Three anesthesia needles went in, and the Yangtze finless porpoise still hadn't passed out after twenty minutes.

Professor Chu was completely stunned. These anesthesia needles were specialized for large animals—even an African elephant wouldn't last more than three to five minutes!

Of course, the finless porpoise is much smaller than an elephant, so the injection amount was also reduced accordingly.

However, under the same dosage, a Baiji Dolphin would pass out in at most two minutes. The larger Yangtze finless porpoise, which has a similar size and physical structure, shouldn't possibly withstand it for more than five minutes!

The dosage for the smaller finless porpoise was less, only half that of the larger one, but it should have been enough.

No matter how you looked at it, there was no way it would take twenty minutes to take effect, but the reality was that the three finless porpoises were fine, as if the three shots of anesthetic had all expired simultaneously.
