Lin Chen was still flying in the sky above the arena. He looked up at the vast blue sky and let out a long breath, "Hah, it seems like wherever I go, there's always trouble. I have to become even stronger. In the higher realms, I am still fragile," said Lin Chen quietly.
Lin Chen looked at the surroundings and waved his hand, storing all the corpses floating in the sky in his inventory.
He also removed the protective bell he had created and descended into the centre of the arena towards Xue Ying.
Lin Chen lightly patted Xue Ying's head, "Good job," Lin Chen said softly.
Xue Ying, whom Lin Chen praised, was delighted, "Of course. Just a small problem", she said, patting her chest lightly.
Lin Chen, who saw his sister's behaviour, just chuckled and smiled. He carried his sister back with one hand and returned to keep all the corpses in the middle of the arena.
