Zi Yan refused to believe it and increased the intensity of her attacks once more. One powerful Dou Technique after another was unleashed, and the surrounding space twisted under the force of her attacks.
Yet Shi Kang remained as steady as a mountain. No matter how frantically Zi Yan attacked, he remained completely unharmed.
After several exchanges, Zi Yan's Dou Qi gradually ran dry. She stood there panting, staring at the still unscathed Shi Kang with disbelief filling her eyes. She even began to wonder whether her Eight-star Dou Saint cultivation was fake.
Zi Yan was only at the initial stage of the Eight-star Dou Saint Realm. Testing himself against her would not allow Shi Kang to determine his true level of strength.
But one thing was certain: Shi Kang was already practically invincible within the Eight-star Dou Saint Realm.
Even if a powerhouse like Lei Ying came, he would have no choice but to admit defeat before Shi Kang and be easily dominated by him.
Having finished testing his physical body, Shi Kang moved on to test his ultimate move, the Myriad Spirit Ball.
The Myriad Spirit Ball fused three Heavenly Flames, Divine Wind, Mysterious Ice, Saint Origin Spiritual Land, and six spiritual items.
Zi Yan definitely could not help him test the power of that Dou Technique.
Shi Kang was afraid of blowing Zi Yan to nothing.
Shi Kang knew clearly that back in the Demon Fire Space, when he had only been a Four-star Dou Saint, he had fused five spiritual items and nearly blown the Six-star Dou Saint Pill Tower Old Ancestor to death.
Now that he had reached the Mid-stage Realm of the Seven-star Dou Saint and had added the Purifying Demonic Lotus Flame, the Myriad Spirit Ball's power would certainly be even more terrifying.
