The nine-colored Sky Mending Fruit, transcending from acquired to innate, can absolutely be called an invaluable Spirit Fruit. Although it does not affect Supreme Warriors, it is still very beneficial for the Martial Arts Tower in the Towering Realm, equating its value to that of Wang Yao.
It enables Warriors, who had initially forged up to the eighth grade of the Martial Arts Tower at the innate level, to supplement the deficiencies of the Martial Arts Tower and thus reach a perfect state of innate formation.
There once was a human Warrior King, who had initially forged the eighth-grade Martial Arts Tower. If he had consumed the seven-colored Sky Mending Fruit or other Spirit Medicines to supplement the Martial Arts Tower, he would have only reached the ninth heaven of the Towering Realm and, at most, stepped into the threshold of a Half-King.
