Lisa said no more after that.
Mazuru was not worried about the safety of those shinigami, of course he was not worried because judging from the reiatsu reaction he perceived, the arrancar who appeared this time were indeed not as strong as last time, at least as far as reiatsu was concerned, it had not reached the captain level.
So it was very likely that, as Mazuru said, Aizen was just doing some kind of test.
'But, what exactly is he trying to test?'
The two powerful arrancars who showed up the first time, and just Yammy who showed up last time, have already shown that Aizen had subordinates comprised of a team of hollows comparable to the captain-level shinigami, and they have already made the Soul Society feel a sense of urgency. So what were this less powerful arrancars for? Was it to tell them that he had mastered the art of making arrancar in wholesale?
To be honest, not only Lisa, but also the entire Visored was quite confused about the Aizen's purpose. What was the point of sending the powerful arrancars to the world of living and leaving after a while? Just to make them feel a sense of crisis?
But this was totally unnecessary.
If they were Aizen and chose to fight against the entire Soul Society, the first thing they had to do was to hide their cards. Only then could they use the arrogance of the Soul Society to gain a greater advantage.
However, thinking about the purpose of Aizen was not something they should consider. Ever since they were plotted by Aizen and became hollowfication's experimental subjects, they and Aizen were doomed to be incompatible.
Either Aizen dies, or they die.
Mazuru stayed with Lisa for a while, and then left after feeling that it was almost time. Lisa glanced at Mazuru and continued to look at the books.
Near the place where Ichigo fought, a figure was hidden in the dark, watching silently.
"You really care about him."
Isshin turned his head, looked at Mazuru who came to his side, and said without any concealment, "Of course I care, he is my only son, and I am quite afraid that something will happen to him."
"What about you, as the leader of this mission of being stationed in the world of living, is it really okay to just watch the team members under you fighting against the arrancars without helping?" He asked the same question as Lisa.
Mazuru didn't feel guilty at all, "What do you mean I am not helping, I'm training them! The young shinigami can only grow if they experience the baptism under some powerful enemies!"
Isshin seemed to agree with Mazuru's nonsense, so he nodded, and then continued to watch with a solemn expression as Ichigo and Rangiku faced off against the two arrancars. The strength of these two arrancars were indeed much worse than that of the arrancars last time. But the destructiveness produced by them was undoubtedly much greater than ordinary hollows.
In the process of fighting with Ichigo and Rangiku, the aftermath of their battles caused great damage to the surrounding environment, and even some unlucky passers-by who walked on the road were affected because of the attacks invisible to them.
The world of living was too fragile, which was why shinigami at the captain and vice-captain level would be marked with a seal to limit their reiatsu when they come to the world of living, in order to prevent huge damage to the world of living.
But hollows were not as disciplined as shinigami. Even ordinary hollows could cause a lot of harm to the world of living, let alone this level of hollows.
In terms of reiatsu, it could be compared to Menos Grande, and in some respects it was even better than the lowest-level Menos Grande Gillian.
In the past, Karakura Town which was always a heavy spirit land, although had occasional visits from Menos Grande, but those were all Gillian-level Menos Grandes, and it was not impossible for the shinigami to deal with them.
But now, with arrancars arrival, nothing was the same.
'Aizen Sosuke!'
Thinking of the chief culprit who created all these disasters, Isshin whispered the name of the other party in his heart.
He hid in the dark with Mazuru, quietly watching his son and Rangiku deal with the two arrancars together.
With the assistance of Rangiku, although the two fell into a bitter fight, they managed to suppress the two arrancars in the end. When Ichigo was about to kill those two arrancars, Isshin saw that Mazuru beside him suddenly moved.
A powerful sword pressure swept across, chopping off the heads of the two arrancars one after the other.
He successfully stole the kill!
"Captain Mazuru!"
When Rangiku saw Mazuru appearing, she was taken aback for a moment, then overjoyed. In front of outsiders, she was more used to referring Mazuru as captain.
"Are you all right?"
Mazuru looked at Rangiku and Ichigo and asked, in fact, this sentence was nonsense, were they okay, could it be that Mazuru still doesn't know after watching all this while?
Of course, they were not alright, although with the help of Rangiku, Ichigo successfully injured the two arrancars, and was about to give them a fatal blow, but before that, it was not so easy to find openings, and the two of them were still injured.
Moreover, Ichigo was the most depressed one, because the head he got was snatched by Mazuru, which made him have no sense of accomplishment at all after such a bitter battle.
"Captain Mazuru, where had you gone?" Hearing Mazuru's words, Rangiku immediately complained.
"Because of some things, I was delayed for a while." Mazuru explained, the so-called some things referred to reading books with Lisa and watching their fight with Isshin.
Rangiku wanted to say a few more words, but Mazuru said first, "We'll talk about it later, I'll go to support Rukia and the others first."
Rangiku immediately shut up.
Subsequently, under the "support" of Mazuru, Rukia and others successively eliminated the enemy.
After getting rid of arrancars who invaded the world of living this time, they did not went to school, but gathered together.
"Tell me how you guys feel?"
Mazuru looked at the people who were all injured and asked.
"The arrancars, they are really powerful." Rukia looked serious.
"I seem to understand why the head-captain announced that we had to enter a state of combat readiness."
The rest of the people also looked silently in approval. After fighting the arrancars today, although they won, they were not in a good mood, because according to the monitoring report of the Twelfth Division earlier, the arrancar who appeared in Karakura Town last time were much stronger than today's arrancars, but even these arrancars had caused great damage.
"Since you think they are strong, then try to make yourself stronger. Only by becoming stronger can you protect everything around you."
This statement was made both to Rukia et al. and to Ichigo.
"Become stronger and protect everything around you?"
Ichigo muttered to himself.
The next day, Ichigo missed class again.
In the headquarters of the Visored, he arrived early in the morning and asked Shinji and others to continue his special training. Although they didn't know why Ichigo suddenly changed his plans, Shinji and others did not refuse Ichigo.
