"Hey, that treasure." When Lu Qing'an followed Lan Yanhao to fly forward, he saw a treasure floating above the fairy field in the center.

This treasure is oval in shape and green all over. When it is suspended in the air, it emits waves of light that spread around the fairy field.

This treasure is not an ordinary treasure, but a top-grade treasure of the tenth grade!

If he guessed correctly, this treasure was one of the reasons why this fairyland could develop so well.

Seeing Lu Qing'an looking at the tenth-grade immortal treasure, Lan Yanhao smiled and introduced it, "This treasure is called the Spirit-Boosting Ball. It's a top-grade tenth-grade immortal treasure. It can make plants grow rapidly and upgrade their levels. It's even more effective than planting immortal herbs in time treasures. Furthermore, I heard that this treasure can only be easily exchanged in the Emperor-level Longevity Exchange Secret Realm of our Fire Clan. Nowadays, almost every top power in the Fire Clan has one. With this treasure, combined with special soil and the use of our Fire Clan's unique immortal herb cultivation technology, we have this immortal herb field."

Lu Qing'an nodded and wrote it all down. When he went to the Imperial Level Longevity Exchange Secret Realm, there was a high probability that he would be able to exchange for this kind of treasure!

He needs to get some more soil, and finally secretly learn the Lan family's magic medicine cultivation technology, so that he can have so many magic medicines in the future!

Be self-sufficient!

From now on, the elixir is free!

(Yesterday I heard that an online writer passed away due to influenza A. I was shocked. Fortunately, I took effective medicine and today I only have a low-grade fever, but I am still weak and confused. Almost every word is squeezed out. Thank you all readers for your concern. When I recover, I will try to resume the three updates.)
