The results were unexpectedly good for them. Under extremely harsh conditions of a level-seven gale, the penetration rate was more than thirty times lower than the other materials. The degrees of corrosion by seawater, rainwater, and various types of water quality require results that will have to wait until tomorrow. If the penetration remains low in these results, then this is the material Polly Sutton has been searching for.
When they left the laboratory, it was already late at night. Jonathan Jones and Michael were outside waiting for them.
Jonathan Jones was there to pick up Grace Yates, while Michael was outside waiting.
