This weak was great in term of progress of stockpiled energy : you reached a sliver above six-tenth of dantians; according to your past experience, this is where the cultivation speed of a given realm peaks. This was at the cost of your last Way of the Spiritual Beast Boundfighter pills though, without any mythical door in sight.
Regarding Metal Melting Truefire, the technique is a true trove of insight about various metals - unlike Unlimited Rising Star Kick, which still feels incredibly good to train. However, it seemed you reached Apex of that one skill, so unless you're looking for a breakthrough there is not much use training it - doubly so as you finished the pills tuned to this practice.

However, one remarkable thing happened before your departure to Stable Lotus Harbor in order to finish the deal you concluded with Ping Jun and LienWen YanEr : you reached deeper insight in your relentless work of the hidden Astral-realm legacy.

Breakthrough of your Bullshit body technique! Chose among :
>Spellmight - burn your Qi to bolster your strength.
It is quite expensive in terms of energy, however this let you temporally replace your low strength affinity by your extremely-high Spiritual Strength affinity.
Assuming you have Spiritual Energy pills or some other high-energy source, this can even be done while picking a "training" action.
Picking this means that your Strength limit becomes your Spiritual Strength limit while working this skill (jumping it from Bad to Exceptional). However, your Body will still limit you and require bottleneck-smashing.
>Powerfist - your Astral Self deliver a harsh punch. Works even if your body is incapacited.
>Mirror-self of the Magus - Summon your Astral Self in place. It can fling one spell at an enemy before dissipating.
>Technique Advancement - create a new technique based on this one. You can add or replace one keyword in the technique
