When Lu Shu saw a herd of antelopes, he was excited. He did not dare to approach the cows that ate lightning, but there was nothing to fear with these cute antelopes jumping about. He caught all of them and stored them in the Seal of Lands.
During the battle on the Tiger's Back, Lu Shu had tested out the environment in the Seal of Lands. When he stored resources and people in the Seal of Lands, almost everyone had suffocated and died. Only three people had survived as they had oxygen cylinders.
Lu Shu realized that if he stored a large amount of air from the Earth in the Seal of Lands, animals could also survive in the Seal of Lands.
The Seal of Lands was much bigger than any invisible storage equipment Lu Shu had seen. For example, Lu Xiaoyu's invisible storage equipment only had the space of a small building. But Lu Shu's Seal of Lands had never been full.
