By collapsing the Heart Image, Lu Li had forcibly created a black hole within the Spirit Realm.
Its diameter was only one kilometer, and its mass was just 0.5% of the Sun's, barely qualifying as miniature.
Yet, Lu Li had exerted almost ninety percent of his strength to firmly restrain it, preventing it from collapsing.
Natural black holes form through the collapse of massive bodies, while maintaining artificial ones requires immense energy.
Fortunately, since this black hole evolved from his own Heart Image, Lu Li found it relatively manageable.
With just a thought, Lu Li could control the enormous gravity contained within, directing it toward Wu Xu.
Wu Xu was not to be outdone and similarly harnessed the power of a black hole to confront him.
The immense gravity from both sides caused severe distortions in the space-time of the surrounding star domain.
Everything, including light, was repeatedly stretched and bent, resembling a giant "funny mirror" continuously spinning.
