When Jin performed the Astral Imitation Style, both the System and Lynn were astonished how he managed to copy the attacks.
This was because the skills are associated with a certain animal style and most cultivators had been restricted to use based on the animal they had been affiliated to. While there had been cultivators who were able to change cultivation styles mid life, many did not succeed because they could not find most of the manuals out in the open to be compatible with their chi.
That's why most cultivators followed their familial cultivation styles because that particular style already had the best compatibility with their chi. Only certain talented cultivators would take up a double cultivation style should their chi allow such compatibility and that was how the Royal Zodiac Clans managed to stay in power for so long.
Those royal clans would not compromise their styles and only allow cultivators who could practice their style to be welcomed if they were inundated into their clan because of love or business related relationships. Thus those who joined usually had practised two cultivation styles to earn their status as a royal clan member.
But in Jin's case, his chi was not limited to his Panda Style mainly because of the infusion of Mana, resulting in the capability to produce Maqi. That not only dilutes his distinctive chi features but also increases the quality of it, enabling him to easily copy a particular cultivation style.
In addition to the full activation of his Maqi production which he had learnt previously under the guidance of Genbu and Orochi, there was no doubt he could imitate other styles without too much of a trouble. The only problem was that weird depiction of the style through his pandas and a slightly inferior attacking power compared to the original. (Of course, for the latter, it can be compensated with additional training and chi output.)
Still, this was a new discovery for the System and it did not hesitate to turn the dial on the trial so that it could get more information on Jin's newest skill. If what Jin had performed was consistent, the System now understood the reason why Ming had collected all those books and cultivation manuals in advance. It was all planned to not make a school out of Jin's business but to increase the skill sets for Jin.
Not to mention, the combination of the System and Jin would greatly increase with this particular method. While it initially thought the System Rider feature would have been a major boon, this new realisation of aiding user through the bountiful collection of manuals would be even more terrifying for Jin's opponents.
This was because the System could simply collate and compile the manuals before hand and analyse which would be the most effective style against a certain cultivator. With its extensive database, it would not be an issue for the System to pull up a few manuals and upload them into Jin's head through a series of quick thought injection spells. (Like how Kraft pushes his thoughts to force a person to do his bidding.)
And that would enable Jin to fight with newly enhanced knowledge against his opponent... assuming the System had enough data with regards to their opponent. But given the trove of manuals that Ming had prepared for his grandson's benefit, including the ones Jin had yet to unlock from Grandma Yuan, the System believed that it was poised to be in an advantageous position to assist Jin in combat despite its severe limitations outside the store.
Now it had teleported two new Wo De Tians to Jin to partake as promised. The more he defeats an enemy, the more they would multiple to add on to the challenge. However, instead of using another style, the Astral Panda Cultivator continued to use Observant Owl with the addition of inserting his own Maqi.
As the Observant Owl Style was mainly focused on wind or air type of chi, Jin had utilised his Maqi to call forth a gust of wind based Maqi that served as duplicated wind blades to enhance his attack. The two Wo De Tian clones did spend more 'fight' time as compared to the first one by performing their first basic technique but eventually were taken down when Jin unleashed three stabs into each of their bodies like how an owl caught its prey and pierced it to death.
The subsequent round had four Wo De Tian clones and this time it was even more exciting as Jin finally used a separate technique even though he continued to use the Observant Owl style. The wind blades which he conjured forced the clones to split apart and when Jin was about to use the very same stabs against the clones, one of them managed to evade the attack, giving him the opportunity to jump Jin while he was on the offensive.
However, his customised sheath came right up, blocking the slash to his face and allowing Jin to retaliate with a quick uppercut, causing the clone to split into two from the defensive strike. It was then Lynn realised the sheath that Boo transformed to, was actually a sword in disguise. Yet, that was not the end as the remaining three did a simultaneous team attack that forced Jin to step backwards. Still, the unsuspecting clones got sliced into multiple pieces because of a wind magic trap attack that Jin had used when he left the spot.
The wind trap spell triggered, causing several wind blades to burst out of the ground, cleanly cutting the rest of the clones into sashimi. But as the remaining three were killed, another eight emerged and took over their place.
It was now Jin changed his Astral Imitation Style and Lynn could see the panda silhouette above Jin started to tear the owl costume away and the remaining smaller pandas went behind it while cloaking themselves under a piece of leather. It was then Lynn was able to discern that they were imitating a snake with the big panda silhouette putting his tongue out while pasting two triangle shaped pieces of paper at the edge of its tongue and wearing two long fake fangs. But the most prominent part of the entire getup?
All the pandas were wearing slippers.
"Astral Imitation Style: Slipper Snake!" Jin shouted as he sheathed his sword into Boo and immediately whipped it out, causing the sword to extend widely. It was no longer a katana and rather, a sword whip. With blades infused with wind Maqi, the sword moved like a slipper through a soapy glass tile, zipping past the enemy and hitting each and every clone at their vital points before it retracts back.
All the clones fell to the ground, struggling to stay alive but the System terminated them so that it could send the next batch of clones towards Jin. Needless to say most of them were not a match to Jin even though he had already been restricted in terms of grade. The System eventually terminated the bout since a minute was about to be up, with a few seconds remaining and based on the data, there was no way those clones could fight toe to toe against Jin.
So instead of wasting resources, the System promised and rewarded Jin what he deserved.. The entire library of manuals compiled into an app for him to browse.
