Misty Mirror Quartz was a special mineral that was often used in fixed arrays in order to disperse and weaken energies before reflecting it to another point.

It had a foggy appearance but was still able to reflect. Lin Mu had obtained a few long chunks of it from the Desolate Blood Battlefield when he had unearthed the Immortal Stone mines. He had never used them before, so there was a decent quantity of them with him.

~SHUA~

Upon slotting the Arrow tip in, Lin Mu could see a streak of darkness trying to enter the shaft. It reached the first couple centimeters rather easily, but after that it slowed down considerably until halting entirely by the ten centimeter mark.

"Huh… that's a lot better than I thought.

" Lin Mu said seeing the effects.

"And time I can visibly see how the curse spreads too.

"

He watched it for a few minutes more just to be sure and then picked up the arrow with his armored hand. Lin Mu wished to see if the effects could spread in any other way. After all, he would have to hold on to the arrow to use it when the time came, so this needed to be done. Using the Longgui Bulwark Armor was a precaution as he could easily disperse it and let go to prevent the curse from reaching him.

"No change.

" Lin Mu watched the shaft carefully, but saw no movement of the curse. This was a good result, but he still needed to test one more thing.

While holding onto the shaft, he applied a little pressure to see how it would hold up.

"Going well…

" he muttered before increasing the force.

He continued to do so for about a minute until finally, the shaft couldn't take it anymore.

~SHATTER~

It broke apart like glass as the force became too much for it to bear.

"It can take the curse well and even allow me to hold it, but will shatter from the force. No way it'll be able to endure the power of the bow, either.

" Lin Mu knew this wasn't going to work on its own.

But he didn't abandon it entirely, as the effects were far too good to do that. 'There might be another method that this can be used…' Lin Mu thought and moved onto the last shaft.

This was also made from a mineral that was considered as a gemstone. It was called as Clear Body Sapphire and Lin Mu had gotten this from none other than the Mermaid Lanbao.

She had given him chests full of gemstones that he had no idea what to do about so they had just been lying in the ring. But now he finally had a use for one of them.

Clear Body Sapphires were highly translucent with a very faint hint of blue and were known for their ability to 'clear' or 'purify' energies.

Because of this, they were often used in Immortal tools and arrays that were meant to be used while cultivating so that there were lesser chances of impure energies being absorbed. In large scale sects that provided Qi directly to cultivation abodes for cultivation, lenses made from Clear Body Sapphires were often used to clear Qi that were gathered from multiple sources.

This made it a lot easier for the cultivators to absorb and utilize.

These Clear Body Sapphires were usually found in small sizes that were less than fingernail in size. Even the big ones were only as wide as a palm.

But among the chests that Lanbao had given Lin Mu, there were large gemstones that were about thirty centimeters wide!

Lin Mu didn't even know how or where she had gotten them from, as he was quite sure they didn't grow to this size. But since he had it lying around, he reckoned he may as well use it.

He of course, didn't know if it could even purify a 'curse' or filter it out somehow, but he reckoned it was worth a try.

Though if someone were to know he was using a Clear Body Sapphire of this size like this, they'd probably spit blood and pass out.

Lin Mu didn't know that a Clear Body Sapphire of this size couldn't be bought even if one wanted to, as there was simply no supply of it. And he had gone one step further and cut out a part right from its middle to use as an arrow shaft, of all things.

Most would think of it was a gross misuse of a valuable resource.

But Lin Mu didn't care for that, as he only cared about the end results.

~SHICK~

He slotted in the arrow tip and saw the curse moving into it. Unlike the Misty Mirror Quarts though, the speed of spread was fast and the shaft turned dark. But as it continued to move further, Lin Mu found that it was narrowing in size.

It continued to taper until it was reduced to a fine point. If Lin Mu held up the arrow, it looked like a stalactite with how the curse had spread.

Eventually, the curse did stop, but it only did so after covering more than seventy percent of the shaft.

"This works too. Didn't expect that it would be able to filter the curse too.

" Lin Mu noted this along with all his previous test results in a jade slip. After all, these were all experiments that were probably never done by anyone else. He didn't even test the toughness of the Clear Body Sapphire Shaft though, as he already knew the answer. It wasn't a hard gemstone, and would definitely shatter from the amount of power that would be exerted by the bow.

But by this point, a new idea was taking root in Lin Mu's mind.

'The materials on their own cannot give me the result I want, but perhaps if I can make use of their unique abilities I might just be able to make the perfect arrow,' Lin Mu concluded.
