They set up the virtual world again for more tries, but they didn't end well. Sean was right about capping their body limits. Although they couldn't kill it in these tries, they better understood its behavioural pattern after damaging the roots of the tentacles. It would certainly help them kill it. When they had capped their limits of 5 strings, they would be nearly two times as strong as a peak athlete was before the Armageddon, without any detriment to their health unlike them. Running well over 60 km/h, and deadlifting hundreds of kilos continuously was normal to them, although the latter achieved nothing in their training and they would be too spent to do other workouts, so no one went that hard. If they went that hard on the workouts, even with their better healing factor, it would take a quite amount of time before they were in peak condition again. With the chest Engraving, this problem would cease to exist and they could exert their full strength easily.
