Level 1 Entry, You Said I Don't Have the Late Stage?

The world is digitized, monsters are rampant, and the era of job transfer for all is coming! Chen Zhou came through time and awakened the whiteboard mage profession. The whiteboard mage has no elemental affinity, no bonus for learning spells, and no way forward for career advancement. He is called the sewer among combat professions! But Chen Zhou, the white-board mage, is different from ordinary white-board mage. You can extract one entry for each level: [Quick Casting], [Spell Damage Increase], [Spell Storm]... Not only that, entries can also be integrated and upgraded: [Swift Casting] + [Swift Casting] = [Double Casting]! [Spell Damage Increase] + [Spell Damage Increase] = [Double Spell Casting]! While the geniuses are still struggling to conquer the difficult difficulty dungeon, Chen Zhou has already swept through the abyss difficulty! "What? You said I'm just a blank slate mage with no post-production skills?" "Go talk to my entry!" [Spell Streamline] + [Concentrated Spell Casting] + [Rhythm of Spell Casting] + [Spell Casting without Delay] + [Perpetual Sequence Casting] = [Skills without Cooldown]! [Quick Spell Casting] +... + [Instant Spell Casting] = [Spell Casting Quickly]! [Spell Damage Increase]+…+[True Damage]=[Ignore Defense]! [Energy-saving Spellcasting]+…+[Mana Permanent Movement] = [Consumption-free Spellcasting]! … In addition, there are many strange entries: [Gaze] +... [Soul Connection] = [Glare at someone who is pregnant]? Ah... This? [Spell Specialization] +... [Dharma Appearance Self-Derivation] = [Spell Automatic Cultivation]? My skills are perfected! [Defense] +... [Immovable Golden Body] = [Eternal Barrier]! Who said the mage was brittle? Stand up!
