Actually, there's nothing much to consider.
Just reserve over a hundred Spiritual Qi to learn Gale Step.
He spent six hundred Spiritual Qi to upgrade Collection and Alchemy to level 2.
Six hundred point Spiritual Qi was respectively allocated to Collection and Alchemy.
[Low-level Collection Skill], level 2 (0/500), proficient (1500/1500), requires Intermediate Skill Stone for next upgrade.
[Low-level Alchemy], level 2 (0/500), proficiency (1500/1500), requires Intermediate Skill Stone for next upgrade.
Production Skills are different from Inheritance Skills and Innate Skills.
Production Skills are generally very difficult to upgrade!
Moreover, when a skill advances, just dumping Spiritual Qi is not enough; advancing Skill Stones are needed.
Low-level Production Skills cap at level 2, if Hang Yu wants to upgrade again, he needs not only 500 points of Spiritual Qi but also the corresponding Intermediate Production Skill Stone... the cost is truly expensive!
