The Soul-Seizing Valley was located in the north of the Saint Spirit Kingdom which was several hundreds of thousands of miles from Summer Rain City. If someone was riding on a horse, it would probably take them two months to arrive. Jiang Yi took over ten days without rest on the Zouwu Beast, but he managed to arrive in just over four days and nights. It was imaginable how desperate he was.
After knowing that the alliance army was attacking the Great Xia Kingdom, Jiang Yi didn't even stop to have a meal and constantly instant-shifted at its top speed. He didn't even rest until he arrived at his destination. If it wasn't for the two Sweet Flag Leaves that he refined—giving a huge boost to his soul spirit, he wouldn't have been able to withstand the exhaustion and would have fainted along the way.
Despite the case, he still felt that he had come late. He scanned the surroundings of the Summer Rain City with his divine senses which caused his heart to sink.
