Bab 1300: The Heavenly Blade's Endurance

When dawn broke, Jiang Hao heaved a sigh of relief.

Last night, after returning from the Devil's Den, he had spent a long time observing the Heavenly Blade.

He did not see any change.

Whether it had been sharpened or something else, he found nothing conclusive.

But from nurturing it with Dao energy, he could tell the Heavenly Blade could be strengthened.

There was a high chance that it had not been sharpened yet.

He was not sure, so he could only go forward and try.

He decided to use Senior Dan Yuan's method to sharpen it first.

In forty-nine days, he would have some understanding of the situation.

At that point, he would rely on his intuition.

If his limit was reached, he would stick to the forty-nine-day cycle.

If he felt that he could handle it, he would try for the eighty-one-day cycle.

He needed to be well-prepared.

He did not know what would happen if he failed.
