Lin Mu was not expecting that he would have really gained the affinity to the metal element, as it was not part of the True Gold Body Forging arts. It was not mentioned in any part of the technique, and it could not have been either.
Gaining an affinity to an element just from a technique was not something that was easily possible.
Most people either had elemental affinities right from the birth, or given to them by a physique or bloodline. This could be seen in the case of Little Shrubby, who had multiple elemental affinities by the virtue of his seven bloodlines, but even then the fire elemental affinity was the strongest.
Lin Mu had the earth elemental affinity innately and had been using it with the Mortal Strengthening scripture. That was the reason why the armor of the technique was so strong and quick to regenerate.
If it was someone without the earth elemental affinity practicing it, the effect would not have been as great.
Then there was the fact that Lin Mu also used fire spirit Qi. For this he didn't have an affinity either, but only his ability to sense it had increased due to the Embrace Of Hong Lin.
It was not on the same level as that of an elemental affinity.
But now Lin Mu had truly gained the affinity to the metal element. The surging metal spirit Qi into his meridians was its proof. If he didn't have the affinity, the spirit Qi wouldn't act on its own to enter his body.
"It really works…" Lin Mu finally said after having confirmed it all.
Jing Wei too, looked surprised at it all and then glanced at the hexagonal container in Lin Mu's hand.
'I told him to sense it… and he drained all the metal spirit Qi from it… Damn, at least I have two more of those left.' Jing Wei thought.
He wasn't really upset with Lin Mu about the use of the metal spirit Qi, as it was nothing compared to what he had done for them. Still, he used that metal spirit Qi for making spirit weapons, and as such, it was a bit important.
The good thing was that it could be refilled later, it would just take some time.
"Hahaha! This is excellent!" Jing Luo congratulated.
"I guess so… it'll take a while for me to get used to it, though." Lin Mu replied.
"Since you have the affinity, you will learn it quickly. Metal affinity is the easiest to use if you already use swords and other weapons. It can be used to amplify the power of most spirit weapons, especially the ones that are of the pure forging type.
With the short sword, you should be able to increase its power by at least two times if you use it with it." Jing Wei explained.
Hearing it, Lin Mu nodded his head.
This was not the only method he had thought of either. Lin Mu knew that he had another technique, the Boulder Collapsing fist.
Lin Mu had used it with fire spirit Qi before and had seen its effect. He had also tested it with the earth spirit Qi before too, but had not used it in a battle yet. The metal spirit Qi could be used in a similar way.
'The only issue is the effect of it… the difference between boulder collapsing first used with fire spirit Qi and earth spirit Qi was vastly different. The same will probably be the case for metal spirit Qi.
I best test it so that I'm not caught off guard in a battle. Not to mention the side effects of it can still be damaging.' Lin Mu thought to himself.
"Guess you can help us too, though there is another issue I'm having." Jing Wei spoke. "Which I doubt any of you can help with." He added.
"Oh? What kind of an issue, Grandfather?" Jing Luo asked.
He was rather surprised that even with three talented people working on it there were still more issues.
"Its more of a limitation in our case, I could say. The forge… it's not stable enough." Jing Wei replied.
"The forge?" Jing Luo repeated, wondering if he had heard wrong.
The forge that Jing Wei had been using in War Castle Jing was the best forge that the Jing Clan owned. Not to mention the Jing clan, perhaps in the entire Xiaofan world there might not be a better forge.
"Yes. The forge is the problem." Jing Wei replied.
"If it's really the forge, then you mean to say the heat is less?" Jing Luo questioned.
"It's not the heat that is the problem. Our forge can generate plenty of heat. The issue is more on its stability. Even with the formation arrays controlling it, there is still a very fine difference in controlling it myself." Jing Wei answered.
"Then why don't we just upgrade the formation arrays?" Jing Luo asked.
"That… is not something we can do either. I've already upgraded it as much as possible with the new insights I got. While it is still upgradeable beyond that, we either don't have the resources for it, or it is simply not possible at our levels.
That is to say… the next upgrade of the formation arrays would put them on the same level as immortal grade." Jing Wei explained in detail.
Hearing this, Jing Luo finally understood the dilemma. To make an immortal grade weapon, they needed immortal grade formation arrays. But then to make an immortal grade formation arrays they neither had the resources neither the cultivation base.
Which if they did, they wouldn't have had a problem making the immortal grade weapon in the first place.
"Well, that will leave us in a loop." Jing Luo shook his head.
He knew that even his skills would not be able to match that of his grandfather and he wouldn't be able to upgrade the formation array, either.
It was now that Lin Mu spoke.
"I may have another method to do it."
