, and Mei's office, even drugging the food and drinks. Unfortunately, Su, now head of the Fifth Science Department, discovered the problem early and dealt with it in time.
During this period, while fighting the Herrscher of Thousands, the MANTISes who had received the second-phase Hyper-Evolution Factor injections experienced unusual physical reactions. They were easily swayed by their emotions in battle and even lost control because of it.
According to Mei's analysis, this was probably related to the fact that these MANTISes had not undergone normal fusion surgery and were now developing their hyper-evolution factors further. After all, such side effects had never appeared before. Thus, Aponia officially began the "Divine Sound" project. However, because of Lingchen's involvement, this version of Divine Sound would not make people extremely obsessive. It would only greatly reduce the risk of MANTISes losing control, though the corresponding increase in Honkai energy would also be reduced.
Aponia no longer made certain decisions without consulting others. Because of her deep connection with Lingchen, she could only see some of the threads of fate. As such, she would not do something as foolish as she had originally done: arbitrarily "reproducing" the Eighth Herrscher's personality while helping Vill-V of the Weapons R&D Department create the Divine Key, Feather of Misfortune, and implanting it into the unfinished Feather of Misfortune, which was still undergoing testing, to assist its wielder.
During this period, although Klein's possession by a Herrscher had something to do with Lingchen, it also reminded Mobius of the original future Lingchen had described for Klein. Thus, Mobius finally developed a conscience. After asking Einstein for the technology, she created a Klein Doll, as well as Gray Serpent, who would go out to transport experimental subjects.
When Lingchen learned about it, he immediately told Mobius to implant foundational
