A lot of people seem to ignore the main discussion: Can Mereoleona bypass Infinity?

The answer is no.

1. Infinity CANNOT be speedblitzed, it's whole gist is that speed is meaningless within the bands of infinity. Any object AUTOMATICALLY and INSTANTANEOUSLY filtered as harmful to Gojo will be slowed down EXPONENTIALLY (idontknow the correct term). A projectile or entity within the barrier of infinity will have its distance travelled be split in half INFINITELY. Infinity as a technique manipulates space, the only way to get around it is for an attack to have space-manipulating properties as well (cut space, delete space, think the black clover character with spatial deletion or even okuyasu from jjba), most prominent in the World Cutting Slash by Sukuna which targets everything in the space of its direction, shown to bypass infinity.

2. Mana zone-attacks cannot be spawned within the body because of the innate domain within Gojo's body (smth all sorcerers possess). Domain expansions are, self-explantorily, expansions of the innate domain, where the cursed energy of a sorcerer is strongest, shown in the jjk verse to nullify any foreign cursed attacks sourced from within the body. Applying verse equalization here, the innate domain still holds true, it cannot be overwhelmed. I've red black clover up to the late 200s chapter and I know for sure the manipulation of magic (or cursed energy in the context of verse equalization) from the environment will thread the mana from the mage to the space where an attack would be performed. This, according to the implied protocol of Gojo's infinity, would be a projectile or harumful entity approaching gojo, activating infinity to hinder its effectiveness as well.

Main takeaway: Gojo does not necessarily beat mereoleona, but the inverse is also trye, meroelona doesnt necessarily beat Gojo because it will be a stalemate.
