System Bestows me with Immortality, Living on to Eventually Become Invincible

In this Mengmu, the price isn't measured by the number of roots, but by how many zhang!

One zhang costs a thousand mid-grade spirit stones. If it's a ten-thousand-year-old Mengmu, the price is even more exorbitant, but the resources invested are also greater.

Rumor has it that the price of a ten-thousand-year-old Mengmu is no longer measured in mid-grade spirit stones, but in high-grade ones!

Many legacies in this sea region have been cut off because of Mengmu, leading to complete bankruptcy. Without a five-thousand-year foundation, don't even think about earning spirit stones.

Cultivating the Mengxu Bi Baoshu requires not only several generations but also more than just spiritual qi.

This sea region is close to the Void Land, filled with various auras that occasionally flow into the sea region.

It absorbs these auras to grow, which is why this wood doesn't grow elsewhere; the environment creates different life forms.

The spiritual herbs and trees of the great world do not gain a year's age every year but must meet their required conditions and environment to increase their age.

Just like the Crane Spirit Tree in the small boundary, if the spiritual qi concentration is insufficient, its age is fixed and won't increase.

In short, these Mengmu, if not carefully tended and heavily resourced, may have their growth fixed at a few thousand years.

Perhaps some Mengxu Bi Baoshu have good growth environments and can reach ten thousand years, but they are rare.

Rumor has it that there is an ancient family in the Mengmu Sea Region, known as the Mu family.

This clan's descendants with Wood Element Spirit Roots are quite prosperous, and they can even use secret methods to cultivate Mengmu, wielding immense power.

Even the Nine Heavens Immortal Sound Array Disk dares not speak much of this ancient clan, usually only mentioning particularly large business dealings.
