The weapon that the two head elders were attempting to forge was none other than a Double Headed Battle Axe.

It was not a delicate weapon nor a precise weapon like the sword or the spear. It was a heavy weapon of wanton destruction and raw power. Making a weapon like this showed that the two Head elders were trying to attempt something new.

After all, most of the Glass Weapons that the Serene Glass Valley made were light weapons like, swords, spears, daggers, and more. Even the great sword that Shuijing Ju was at the upper limit of what the Serene Glass Valley had made before in terms of weight class.

This was due to the natural properties of the Snow Glass Pear Tree sap. It could offer amplification to formations and add good weapon skills, but for actual durability and direct power it wasn't ideal.

Instead of using a valuable material like that one, could use several other cheaper materials and obtain the same level of power. After all, the glass weapons were meant to be Skill type weapons rather than pure forging or hybrid type weapons.

Which the Double Headed Battle Axe usually was.

But Lin Mu didn't think it was right to judge it just now.

'The Head Elders must have some other reason for doing this… Otherwise I doubt they would pick a weapon type like this.' Lin Mu thought to himself.

Lin Mu continued to observed and the two Elders moved onto the next major step, which was to fill the mold with the sap.

"Take out the sap,

" Head Elder Dajian spoke as he prepared to make his move.

Head Elder Heng did as instructed while controlling the Yellow Flames.

~shua~

A large chunk of crystallized Snow Glass Pear Tree was taken out of his storage treasure. It looked to be rather pure too and had probably been collected over a long time since it was a single chunk.

Lin Mu didn't think it was made by combining multiple smaller crystal. This was due to the fact that the sap could only be melted once after solidifying on the tree.?Doing so would break its structure and make it very fragile.

Hence depending on the size of the weapon that needed to be made, the sap chunk needed to be the right size.

~CLACK~

The crystallized sap chunk landed on the lower half of the weapon mold before Head Elder Heng increased the flames.

~SHUA~

The flames heated the base of the mold, to avoid touching the sap directly with the flames. Directly heating it with the flames could lead to excess tempering of the sap, and lead to it boiling instead.

This would result in a poor quality weapon and its ability to retain and amplify formations would also degrade.

"Time to switch.

" Head Elder Heng said, surprising everyone.

"They're switching in the middle?

"

"Won't that result in fluctuation of the flames?

"

"Yeah that can lead to faults in the sap!

"

The juniors were confused by the decision of the Head Elders. They could only watch as the two elders did as spoken.

The control over the Flame Soul Lamp was instantly handed over to Head Elder Dajian who didn't let the flames flicker for even a single moment. There were no fluctuations, showing just how great both of their control were.

'What did they do this for?' Lin Mu wondered before seeing that Head Elder Heng had taken hold of the Axe handle that they had made earlier.

~HONG~

Then in the next moment, Lin Mu felt Dao Traces in the air which came from none other than the Head Elder in question.

"Whoa! Is that Head Elders Dao Embryo?

"

"Yeah that's the Bone Carving Knife Dao Embryo.

" The Juniors recognized.

~HUM~

The Head Elder directly took hold of his Dao Embryo and stared carving runes onto the wooden handle.

"He's actually carving them by hand!

" The Juniors were astonished and impressed at the same time.

"His head is so steady. I could never do that myself.

"

Watching this though, Lin Mu knew that the old man had gotten this idea from himself.

'Is he trying to layer them?' Lin Mu guessed.

He waited for a few minutes, and watched Head Elder Heng carve runes onto the handle while the other Head Elder steadily heated the bottom half of the weapon mold.

The Snow Glass Pear Sap had started to soften and a small layer of it had already melted at the bottom too. And by the time half of the sap had fully melted, Head Elder Heng had finished carving runes on the handle.

~SHUA~

Upon their completion the runes glowed, but did not turn into a complete formation.

"He really is layering them… the runes do not result in a full formation until the second layer is connected.

" Lin Mu muttered in understanding.

Shuijing Mingzhu listened to Lin Mu's words, understanding the actions of her Great Grandfather as well.

"Coat it!

" Head Elder Dajian shouted with a hint of nervousness.

Head Elder Heng used his Immortal sense and controlled a bit of the molten sap, using it to coat the wooden handle!

This was astounding, as doing this could be considered a mistake in the general sense. It would lead to there being a disjunction between the blade of the Axe and the handle.

"So that's why they decided to do layering…

" Unlike the confusion of others, Lin Mu was instead impressed by their methods.

~SHUA~

In just a few seconds, the entirety of the wooden handle was coated, and the Head Elder took hold of his Bone Carving Knife Dao Embryo once more.

This time though, he coated it with immortal Qi, and created an additional surface on top of it. He then used this to carve runes into the surface of the handle which had been coated with a layer of sap.

~HUALA~

This time the old man was even faster than before. The top of the carving knife never actually entered the sap, only the immortal Qi did, and yet the effects of the Dao Embryo were still implemented.
