Lin Mu listened to the Saintess' words in detail and memorized them. Since he already had a decent mastery with the formations, it wasn't that hard for him to fully understand the methodology.

The method was simple for him, as it was the same as creating small runes that could be linked together into a tiny formation that would be able to work on the veins.

Of course, making formations on living things was entirely different than laying them on inanimate objects. Not only were there greater chances of making mistakes, there were also factors such as the natural flow of Qi and vitality that could also affect the formations.

Either they would become disturbed, or would not be able to be created. And even if one did manage to make them, there was no guarantee it would be stable enough to work.

As such, one needed to be an expert at formations in order to make them work on living beings.

Then there was also the factor of how big of a formation one was making and how complex it was. Smaller formations would have a better stability as they were simpler in nature giving them fewer avenues of disturbance.

The larger formations on the other hand were opposite and would not have the same stability. In fact, there was as chance that one wouldn't even have enough space to make them in the first place. Especially in a narrow space like the veins of a tiny bird.

Still, for Lin Mu who had made formations even smaller than that, it was a new challenge that he took on with a whole heart.

~shua~

His immortal sense scoured through the blood vessels of the tiny bird and marked each of the traces of the Vein Snapper Venom that was present.

Once Lin Mu knew where all of them were, he started to work on making the formations.

He laid the runes one by one, making sure that no harm was being done to the bird and that they were also stable. He progressed steadily, not wanting to make a mistake that could cost too much.

He was slow at first, taking a whole half an hour to make the first formation.

This was a very simple formation called as the Qi Dissociation formation and was often used in combination with other formations to make a Qi channeling array.

One could consider this Qi Dissociation Formation to be a coating that would be applied inside of a pipe to prevent the fluid or other things from sticking to it.

As such, the same Qi Dissociation Formation would be carefully applied in the veins where the Vein Snapper Venom was present causing it to detach from the veins.

The area of effect of the formation was not that wide on its own, being microscopic. But once more of them were added, they would work in tandem and have a multiplicative effect.

As such, when a few hours had passed, Lin Mu's speed had increased by quite a lot and he was making the formations much faster than before.

Now it barely took him a minute to make a formation and it was still decreasing.

And eventually, Lin Mu was making them in barely ten seconds.

It took him a total of twelve hours before Lin Mu finally completed all the Qi Dissociating Formations.

~huu~

Taking a deep breath, Lin Mu looked at the bird which was still alive, albeit weaker.

"And here we go,

" Lin Mu said and injected Qi into all the formations at once, activating them all!

~SHUA~

As soon as he did, the formations lit up and a surge of energy washed through the tiny bird's body. It was like a river washing away all the impurities that were stuck in its veins and it all came out of its leg that had been bleeding.

Instead of red blood, dark green liquid dripped out.

It was just a single drop, but the obnoxious feeling one could sense from it was alarming.

"So that's the Vein Snapper Venom.

" Lin Mu narrowed his eyes.

"Indeed. Even a single drop of it is enough to take down a beast.

" The Saintess replied.

"Though… it is surprising that a beast as small as this has managed to withstand it all this time.

" She said with surprise.

She too was unable to tell just what the bird was other than the fact that it looked similar to the Snow Stream Sparrow.

But before they could question any further, a change started to happen in the bird.

~CHIRP~

It suddenly let out a loud chirp and its vitality increased.

Lin Mu's immortal sense was still inside the bird's body, and as such, he could observe the change in even greater detail. There he saw how the vitality which was continually being sapped by the Vein Snapper Venom was now returning.

The tiny bird's cells burst out with energy and produced a lot of vitality.

'Is this due to the healing pill that it ate before?' Lin Mu wondered.

He checked the bird's Dantian and saw that he was indeed correct.

When the tiny bird had first eaten the pill, its effects had not worked but they had still been absorbed into the Dantian. And now that the Vein Snapper Venom was gone, it could take effect and fill its body with vitality and begin the healing process.

They all watched as the injured leg of the tiny bird healed and returned to perfect condition.

Not just that, but the bird also had a vibrant look in its eyes now.

~CHIRP~

It looked at Lin Mu and let out a happy cry.

~FLAP~

It then opened its wings and quickly rushed to Lin Mu, coming to stand on his head.

~CHIRP~CHIRP~CHIRP~

It then hopped around happily on Lin Mu's head, making the man chuckle.

"Haha, guess it's back to its peak health.

" Lin Mu said.

"It says that it is thankful to you.

" Little Shrubby translated for the bird.
