Chapter 421: Blood-Red Blade Light

His gaze swept over the Golden Elixir Cave Mansion in front of him.

Looking at the lush spirit fields and Medicine Gardens before him.

He Song's eyebrows furrowed slightly.

He always felt as if he had forgotten something.

Soon, after some thought, a glimmer of light gradually flashed in He Song's eyes.

Spirit Qi!

That's right!

It's the spirit Qi!

As He Song's gaze scanned the surroundings, he had already discovered a problem.

In this cave mansion, apart from the Divine Thunder Array he had set up himself, at first glance, there seemed to be no other Array Skills present.

But, the spirit rice and spirit medicine in those spirit fields and Medicine Gardens that have been growing lushly until now, where do they absorb the spirit Qi from daily?

If it was said that the spirit-gathering effect came from the previously completely dissipated Defensive Great Array, He Song, with his sharp eyes, would've seen it early on.
