Xiao Feng's modification of the Shadow Demon Bull Wolf had a purpose.
So, spending more energy was justified.
Each modification cost one hundred and eighty thousand.
This was just the price of the modification, not including the cost of increasing the success rate.
Therefore, each modification cost more than two million.
In the end, Xiao Feng spent thirty million to modify the Shadow Demon Bull Wolf into a ninth-tier zombie with a 9+ enhancement.
Shadow Demon Bull Wolf: Ninth Tier 9+
Skills: Shadow Charge, Demon Claw Attack, Iron Tail Abyss Break...
Loyalty: 100
...
This was like equipment in a game; when you upgrade it to 9+ or above, whether it's attack power or other attributes, there's a significant boost.
Xiao Feng could confidently say that, at the current ninth tier, the Shadow Demon Bull Wolf was almost invincible.
Even tenth-tier zombies would need to avoid its sharp edge.
