Su Xiao closed the information panel for Gun Master. The cost of upgrading Gun Master was strange: expensive at the early stage, normal in the early-mid stage, expensive in the mid stage, and gradually returning to normal after reaching Grandmaster Lv.20. This was likely the bizarre cost curve caused by forcibly improving a technique-type ability.
Compared to the cost of upgrading Swordsmanship Master, Gun Master was nothing. Su Xiao tried to upgrade Swordsmanship Master, and a prompt immediately appeared.
To upgrade Swordsmanship Master Lv.60, Soul Crystals ×10 and 650 Soul Coins were required.
After Swordsmanship Master broke through the Lv.60 threshold, the required Soul Coins were not much in Su Xiao's eyes. The main problem was the Soul Crystals. Those were the truly troublesome Big Head.
Aside from that, Su Xiao discovered something through the upgrade cost of Swordsmanship Master. Previously, raising Swordsmanship Master from Lv.59 to Lv.60 had cost Soul Crystals ×10 + 8.5 million Paradise Coins.
After Swordsmanship Master reached Lv.60, the required Soul Crystals per level remained unchanged, but the other cost became 650 Soul Coins.
The price gap between 650 Soul Coins and 8.5 million Paradise Coins was astonishing. One Soul Coin was equal to 150,000 Paradise Coins.
Seeing Swordsmanship Master's current upgrade cost, Su Xiao's most direct feeling was that upgrading abilities in the past had been far too cheap, almost like preferential treatment.
Or rather, the existence of Paradise Coins itself was a form of preferential treatment that was difficult to notice—a benefit for Contractors in the early and middle stages. After all, Paradise Coins were only accepted within Reincarnation Paradise. In other paradises, such as Apocalypse Paradise and Death Paradise, Paradise Coins were not accepted.
Reincarnation Paradise used Paradise Coins as currency, Apocalypse Paradise used Paradise Points, and Death Paradise used Death Gold.
