Zhang Tie was repeating the extremely boring process of cultivation using his spiritual energy in the void...
This process was so monotonous that it almost drove Zhang Tie mad. After gathering the two energies in the void, Zhang Tie would let them dissipate themselves. Zhang Tie repeated this process tens of thousands of times. He still continued it even when he became completely numb spiritually and turned the whole process into an instinctive and mechanical response.
Zhang Tie hoped that he could mobilize the two energies as freely as taking a breath one day.

He had to repeat the hard process of cultivation for numerous times to make a bit of progress. In the process of cultivation, he was accompanied by loneliness.
