Qin Wentian trembled, speechless for a moment. Yes, the immortal realms was just too vast. Qingcheng was afraid that it would be too difficult for them to meet if she came here. It wouldn't be easy for immortal kings and emperors to search for someone precisely given how vast the immortal realms are.
He made a promise that he would be back. Hence, Qingcheng decided not to leave the particle world, she wanted to wait for him to come back.
"Nothing will happen to Qingcheng!" Qin Wentian silently stated. After settling the Battle Sword Sect's matters, he would immediately head back to the Royal Sacred Region to look for her. He can't waste a single moment.
