Song Shuhang was a person with a strong heart. People like him often remained calm and composed even in critical situations. Their robust mental resilience allowed them to make rational decisions when facing extreme challenges.
In order to eradicate the liquid metal within the Heavenly Tribulation Realm, Song Shuhang had limited options due to the restrictions on his Inner World, which prevented him from using many external means. He needed to find a solution within those limitations.
Apart from the Krypton Gold Strike, he had a few other potential methods that included the Karmic Saber and a sealing technique he initially intended to use against the fat ball, namely the Holy Ape World Refining technique along with mysterious Whites 1-33.
