He only just graduated today and he was already facing off giant swarms of hollows and nearly died in one day. This was the exact opposite of what he imagined his first day would be like. He thought that it would've been rather slow and boring as he would be treated like a scrub by senior member's of his squad but instead he was facing hordes and hordes of horrible monsters with a very high chance of dying. He still wouldn't have it any other way. If he was going to get respect as a shinigami then this is the best way to earn it. A real shinigami has to go and face adversities that they themselves must face in order to grow and become a true warrior that his peers could approve of. 

Zheng rammed his elbow through the mask of a hollow while balancing on one foot he kicked a hollow climbing onto the roof that he was on, causing it to land on its stomach. His body's movements when observed flowed easily as he moved out of the position he was just in and leapt into the air, performing another flip as he stomped down on the hollow's back when landed, forcing it and pointed his right hand with his index finger pointed at it, glowing with a bright blue aura. "Hado 4: Byakurai." A bolt of energy shot of his finger and blasted through the creatures skull, destroying its mask in the process. 

"Just how many of them are-" He was suddenly cut off as a hollow leapt at him from, it's mouth wide open with its fangs ready to sink into his flesh. Zheng's eyes widened in surprise that he made such an error to not notice the creature and he knew didn't have enough time to counter or even dodge. The hollow's fangs sunk into his shoulder; or so it would've thought. It's fangs couldn't even break through the man's skin no matter how much pressure it put on its prey's body. A grin remained on his face as he saw the monster's confusion to why it couldn't harm him. "Tempered Iron Will." He quickly smashed the skull of the hollow with ease, using a back fist to kill the creature. 

Several hollows ran at him, their foots steps heavy and caused the earth to tremor. The young shinigami turned to them with his right arm raised in front of them as it glowed bright blue with a fiery flicker. "Hado 33: Sokatsui." A torrent of blue energy was released from his palm, tearing through the area in front of him and obliterating the hollows in front of him. "This surely is one hell of a day..."
