In terms of Spirit Plants, they were basically Spiritual Medicines from the Heavenly Realm, since the Spirit Plants of the Infinite Star Sea grow on fixed Stars, with only a few varieties that can grow universally. This time, one such variety was also delivered.
Spirit Star Flower: It can gather starlight and Spiritual Energy and can also be used to feed Spiritual Beasts, whether they are from the Star Sea or the Heavenly Realm. This is a very common Star Sea Spirit Plant but extremely practical.
As for Spiritual Beasts, there were relatively few; only 3,000 Cyanwood Triangle Bulls were sent. Chen Jiuge had seen this type of Spiritual Beast before, reputedly the Spiritual Bulls responsible for farming in his Master's Grotto Heaven.
