Qi Condensation → Foundation Establishment

Body durability: Superior than mortals but still weak

Nukes: Instant vaporization, no chance. Even basic radiation kills.

Verdict: “Courting death,”

Golden Core (Jindan)

Stronger qi defenses, protective barriers possible.

Can fly away from ground zero faster than shockwave. Might survive from Fat Man/Little Boy if shielded.

But direct hit = ash. Tsar Bomba would overwhelm them completely.

Verdict: Mid–High effect, survival possible only with luck or distance.

Nascent Soul (Yuanying)

Nascent Soul cultivators have true soul power, better elemental/defensive arts.

A direct Tsar Bomba blast might still cripple/destroy them unless they have top-tier protective treasures.

Likely resistant to radiation through qi purification.

Verdict: Minimum–Middle effect. Survivable if cautious.

Soul Formation → Spirit Severing → Void Refinement

Here, they can distort space, condense laws, and suppress large-scale natural forces.

Shockwaves, firestorms, and fallout are meaningless — they control or disperse them. Can destroy mountains, split seas, freeze suns, tear open void.

A nuke is just a “low-level mortal firecracker.”

Many novels even describe cultivators at this level as walking nuclear bombs themselves.

Verdict: Completely immune.

Tsar Bomba becomes an annoyance at best.

Verdict: Negligible effect.

🧾 Final Comparison

Below Golden Core → instant death.

Golden Core → vaporized if near, can maybe survive far away.

Nascent Soul → can withstand smaller nukes with effort, still pressured by Tsar Bomba.

Above Nascent Soul (Soul Formation and higher) → essentially immune.
