Using bloodline aura was a method that was often used by beast to keep other beasts in check.

They would use their bloodlines to suppress weaker beasts, as a method of domination. But when a beast or creature had a sufficiently strong will, they could resist this suppression and might even be able to oppose it.

If they were successful, there was a chance they might even be able to improve their bloodline.

It was a method of purification through raw pressures.

But much to Lin Mu's surprise, he received a different answer.

"No.

" Xukong stated.

"It won't work?

" Lin Mu wondered what was the reason.

"Yes, it won't.

" Xukong confirmed.

"While the Bloodline of the Great Slumber Bear is strong, you're forgetting it is inherently a beast bloodline. The Dark Elf Bloodline is a humanoid bloodline and wouldn't respond in the same way to it as other beast bloodlines would. Of course, it would try to resist it too, but it wouldn't stimulate it.

" He explained.

"Then what kind of pressure should I use?

" Lin Mu asked.

"One that you are more used to. One that can be applicable to everyone regardless of race.

" Xukong replied.

"Pressure of death, a threat to life.

" He stated.

Hearing that, Lin Mu got the idea of what he was supposed to do, but was hesitant.

"Using Slaughter Aura for that…

" Lin Mu muttered.

"You don't have to go for that right away. You try something a bit 'lighter'.

" Xukong suggested.

"For example, your sword intent itself.

" He added.

"True… That should be more reasonable.

" Lin Mu nodded his head.

He knew just how pressured everyone had felt when he had progressed in his Sword Intent. With the guidance from Xukong, Lin Mu was now ready to try it out.

"I think I can help you improve in another way Ziran.

" Lin Mu said, before giving him a gist of what he intended to do.

Ziran's eyes went wide hearing it, as it was a bit severe.

"Hmm, it might just work.

" But Ziran was not one to back down from something like that.

"If you agree, we can try.

" Lin Mu replied.

"Of course.

" Ziran answered.

"We'll be facing far worse threats anyway.

" He stated.

"Alright.

" Lin Mu said as he stimulated the Sword Intent within him.

"Get ready,

" he said as a sharp energy started to exude from it.

Ziran instantly felt it and the hair on the back of his neck stood up. Even if his cultivation base was higher than Lin Mu, he could already tell that the threat he was facing was of an equal if not higher level. And this was only going to get stronger, as soon his entire body was covered with goosebumps.

~HUALA~

Lin Mu's eyes turned sharp as if swords were threating to jump out of them at any moment. If anyone were to look at Lin Mu at this moment, they would find their hearts beating wildly and make them avert their eyes.

But Ziran held on, watching without looking away. If he wished to improve his Eyes of the Underdark, he needed the pressure to be directed exactly to his eyes.

But as he continued to watch, the pressure turned his eyes red. His long slanted eyes that gave away a hint of his Elven heritage were now tense, as veins started to pop up in them. A couple minutes later, his eyes had turned blood shot.

Five minutes later, they were watering and tears continue to train down the side of his eyes.

And yet, he didn't look away. He didn't even blink!

Ziran could tell that the method was working or was close to working, as he was feeling the change in his eyes.

The Eyes of the Underdark bloodline skill was active at this moment, and Ziran was not only looking at Lin Mu, but also beyond him. In the dark shroud of Death Qi, Ziran was unable to see anything at first, but now he realized that the shroud was getting seemingly lighter.

The shade had changed by only a couple of tones, and the wall of death Qi around them was still darker than the night. But it was still an improvement from before.

This was already more progress than he had for the last couple months. And Ziran had a hunch that this was not the limit either.

He continue to endure Lin Mu's Sword Intent as it continued to increase. Ten minutes passed like this, by which drops of blood were leaking out of his eyes!

Lin Mu was concerned about this, but wouldn't disrespect the man by simply stopping right now. Until the man said so himself, he would do what he had acquiesced to do.

"I'll take it up another level.

" Lin Mu warned.

"Get ready!

" he said out loud.

Ziran could only nod before he saw Lin Mu's lips move.

Unknown words came out of Lin Mu's mouth, hearing which made Ziran's ears go numb.

Strange chants were uttered by Lin Mu, that made his own eyes still down further. A few seconds later, it was as if an army of swords was raging in Lin Mu's eyes while his body let out a pillar of sword intent!

~HONGLONG~

The pillar of sword intent directly reached the limits of the mountain base's barrier.

If not for the fact that Lin Mu was controlling it to not harm anything, it might have already broken through a few layers of the barrier.

The sharpness of the Sword Intent was impeccable since it was at the the Peak level!

At this stage, only a sliver of it would be enough to cut off the heads of Immortals if they were careless.

Even looking at it without defenses was dangerous as could be seen from the lines of blood that were now trailing down Ziran's eyes.

But as the blood continue to trickle down his eyes, his vision only got clearer.

With each drop gone, it got better and better, until finally nothing clouded his vision!
