Strictly following the principle of "payment in one hand, goods in the other," Luo Qian paid the balance for the first Stone Tablet, then left the Netherworld with the souls of three master landscape designers. Although he had found the specialists he needed, he was in no hurry to return to the Saint Realm. He took the three of them sightseeing through the Divine Realm and the Demon Realm. The Immortal Realm was out of the question; they would be spotted too easily. As for the Buddha Realm... even if that desolate place had once had vegetation, its fanatical monks had long since chopped it down to carve Buddhist scriptures.
At the three designers' request, they collected countless kinds of seeds along the way. Luo Qian handled the gathering, while the three sorted the seeds by category and stored each kind separately. He knew nothing about the subject and never interfered.
That detour cost them another dozen days or so. Luo Qian did not sit idle while the three classified their finds. Plants were not the only things the Saint Realm lacked. Those barren planets had no vegetation, let alone animals. Whenever he had a chance, he climbed mountains to catch tigers and went down to the sea to net fish. He also collected a motley assortment of Magic Beast eggs. Planets that had been greened would need animals to bring them to life.
Luo Qian still felt it was not enough, so he prepared some rocks and lake water as well and took them all to the Saint Realm. After all, things from the Demon Realm and Divine Realm did not contain Immortal Aura like things from the Immortal Realm, making them easy to detect. As long as they were not energy Crystal Stones, there would be no problem.
