While Li Qixuan was stunned, Du Beiye smiled proudly.
Although she was stronger than her sister in terms of combat, her sister's mental fortitude was the best in the entire Tarakam Civilization. This was the main reason why Gaia had chosen her sister instead of her.
To use Gaia, not only must the host have a high level of empathy and rich emotions, but the host must also possess immense mental energy. Between them, her sister's mental energy was several folds higher than her own. So it wasn't strange for her sister to be able to collect an item of that size so easily.
It took Jiao Lizhi almost an hour to collect all the underground tanks. When she was done, her back was drenched with sweat, and she had to take a break to recover her mental energy.
While she was resting, both Du Beiye and Li Qixuan continued clearing the zombies in the area. Li Qixuan didn't care about the crystal cores, so he only focused on killing more zombies and training his combat skills.
