Sen had a look around to see if anyone was there or not and began his meditation just before the giant wall. The next time he opened his eyes, it was already the night of the fourth day. From day one to till that time, all he was doing was meditation, meditation and meditation.
Though he stopped the leakage of the profound knowledge and the profound energy, he spent a majority of his sage energy and his valuable mental energy in it. Sage energy would have filled itself inside his soul sea with time, but that was not the case with mental energy.
To fill the amount of sage energy used before he had to sit in meditation for days.
Since it was night time nothing was visible. While he was pondering where to go next a big arrow passed by his side. Sen was able to react in time and made some distance before it exploded.
