Even if the fragments of the Chimera Plant were limited, there were other strong materials that could be switched in for it. The piercing effect could be weaker, but one must remember that even Seventh Tribulation Stage Immortals did not have the same level of defense that the Chimera Plant had.

Something even half as strong would be more than enough to pierce through the defenses. Thus, they could see the value of the arrows.

"Maybe.

" Lin Mu replied after hearing his words. 'It might be good to have a few of them in reserve just in case. I can use them against other foes or beasts if need be.' He thought to himself.

"We'll think of that all later. First we'll help you make the very first of them.

" Crown Prince Feng Shun stated.

"Of course!

" Qiao De was very enthusiastic about it now.

"Let's go then.

" Lady Kang was the same.

Everyone wanted to see the birth of such an arrow and they quickly went to Lin Mu's room that had now been turned into a Foundry.

~SHUA~

As soon as they opened the door, the hot air washed over them. Thankfully, they had already been warned about this, so were able to defend against it with no issues. Though this was still a lower temperature than what Ziran, Daoist Chu and Crown Princess Shang had been hit with earlier.

"You weren't joking.

" Elder Hu spoke.

"This is quite hot.

"

"It'll get significantly hotter.

" Lin Mu cautioned them.

"Especially when we get to forging the Null Iron Ore.

"

"I got us covered!

" Qiao De said, taking out two stacks of talismans.

"Heat warding talismans, everyone take twenty!

" the man was certainly being a lot more generous.

Those who knew Qiao De would say that it was incredibly rare for him to give anything for free. And yet, he was handing out a two hundred Heat Warding Talismans casually. Though it was definitely due to the opportunity of contributing to the arrow that Lin Mu was making.

After all, if he had a hand in it, it would be a lot more legitimate for him to get the other versions later.

"I'm okay.

" Lin Mu replied.

"You all can use it though.

" He stated.

"Don't mind me if I do.

" Daoist Chu quickly took his share of the Heat Warding Talismans. He slapped them all onto his body at once, knowing that it won't be good to do it inside.

The others did the same, though they also kept their defensive skills active. They didn't know how much energy they would have to use for the forging though, thus it was good to have the talismans to help them with the heat too.

But Lin Mu was doubtful about the Talismans and how long they might last.

'A single Heat Warding Talismans can handle the heat of a volcano for a bout fifteen minutes… twenty should be enough… maybe…' Lin Mu thought to himself.

After all, he didn't know what level of heat they would be reaching in the end.

~step~step~step~

Once they were inside, they could see the large space that had been created.

"Whoa… This is really a proper foundry at this rate.

" Crown Prince Feng Shun said, feeling impressed.

"Only thing it's lacking is an Earth Fire Vein.

" He observed.

"I think if Daoist Mu Lin had more time, he could've set up that too.

" Monk Hushu guessed.

"I don't think this plane has an Earth Fire Vein, so I wouldn't have been able to add it, regardless.

" Lin Mu replied.

"Most Spatial Planes don't have Earth Fire Veins and if they do, they'll usually be of a different kind than Bridge Plane.

" He explained.

"I didn't know that,

" Monk Hushu replied.

"Me neither.

" Qiao De said too.

The group quickly reached the floor where the work was to be done.

"So, what do we do now?

" Elder Hu asked.

"Give me a minute,

" Lin Mu said as his immortal sense connected with the array he had made.

~SHUA~

A few seconds later, the array activated and nine pedestals formed from runes appeared. These pedestals were connected to the pool under the crucible and the lava was also being channeled into this.

"Little Shrubby, I'll need you for this,

" Lin Mu called out his trusty companion.

~HUALA~

The beast quickly enlarged to his full size, taking up a decent part of the area.

"I need your flames to melt the Null Iron Ore. We'll be adding our Qi to provide additional heat as well.

" Lin Mu instructed the beast.

"Alright.

" Little Shrubby said, but when he looked at the Crucible, he thought of something.

"That thing won't endure the heat.

" He said, pointing to the crucible.

"Hmm… true.

" Now that Lin Mu thought of it, the heat they would be producing would certainly exceed the melting point of the Crucible that Lin Mu had made out of Hot Mantle Clay.

It was a special type of Earth material that was found deep under volcanoes. It managed to stay in a solid state even when it was heated to a high temperature and was one of the best materials to make crucibles out of. Lin Mu had, of course, obtained it from his many endeavors.

But even something like this wouldn't be able to bear the temperature needed to melt the Null Iron Ore. It might be good enough to endure the heat of volcanoes, but Lin Mu had already been using Lava to provide the heat for melting, which hadn't been working.

A temperature higher than that would certainly be beyond the limits of the Hot Mantle Clay. Lin Mu didn't wish to see what would happen if they tried to melt the Null Iron ore in it. They might even succeed in doing it, but the Hot Mantle Clay would also end up mixing in it, thereby adding more impurities.

"What else can we use for that?

" Lin Mu muttered to himself.

"Meld wouldn't work either, as it would isolate the space.

"
