Sudo Kirihiko's side, after returning to the mansion of the Sonosaki family, he searched everywhere for Sonosaki, but he couldn't find it after looking around, according to the servants at home, he had seen her just now.

Just when he was deeply surprised, he found that a secret door hidden in the wall suddenly opened, and Sonosaki walked out of it.

Sudo Kirihiko, who already had doubts in his heart, did not step forward, but subconsciously hid aside, and waited for Sonosaki to return to his room, only then quietly touched the direction of the secret door, and found a mechanism according to the method of Sonosaki to close the secret door before, and successfully opened the secret door.

And when he walked into the secret door, he didn't realize that all his actions were seen by Sonosaki Wakana who walked out of his room.

However, she did not stop Sudo Kirihiko from entering the secret door, because ...... Even she didn't know that there was such a secret passage in her home!

"Is this the gateway to the well of the earth that the bastard detective said?" Sonosaki Wakana frowned and thought about it, but she was afraid of bumping into Sudo Kirihiko, so she didn't follow directly, anyway, the secret passage was in her own house, and she could go anywhere.

What she didn't know was that she had already been to the underground place, but the entrance was not in her own house at that time.

The current entrance was built by the Sonosaki Ryubei after they built their Sonosaki family's mansion on the ground for more than ten years.

As the saying goes, curiosity kills cats, and if you don't have enough strength or the aura of the protagonist, it's not a good thing to know too much, and Sudo Kirihiko is going farther and farther on this way of death.

Walking into the secret door, through a passage, into an elevator, and after a rapid descent of at least a few hundred meters, an ancient passage appeared in front of Sudo Kirihiko's eyes.

"What is this place?" Sudo Kirihiko walked into this narrow passage in disbelief, and then came to a vast space like a ruin, "There is such a place under the Sonosaki family!" ”

Most of the ruins were scattered stones, except for a well-mouth-like device in the middle, and Sudo Kirihiko could see the light coming from the well when he stepped forward.

"What the hell is this......" Kirihiko Sudo muttered to himself.

"This is where our Sonosaki family gets the memories of the earth!" A startled voice sounded, but it was Ryu Sonosaki, who was holding Miku, who came over, "That's why Gaia's memory was born!" ”

"Father-in-law!"

"Kirihiko, welcome to the museum!" Sonosaki Ryu Bei smiled.

"Earth's memory is still mysterious, so we have to experiment!" Ryubei Sonosaki put down Miku and operated a few times on an electronic instrument next to the well, and a data-like colored light suddenly rose in the well.

"So we let the Gaia memory circulate in the wind capital."

"And now we're interested in the Bird Memory!"

"Could it really be that we gave the bird memories to those children?" Sudo Kirihiko said in disbelief.

"After all, the more immature the child, the more accurate and effective data we can get!" Sonosaki Ryubei smiled and nodded, "Their pure and flawless spirit and body can make the bird's memory evolve dramatically!" ”

"Then, we will finally break through the limits!"

"Does it mean that all humans who use it will die?!"

"They won't die in vain, the data we get is the great contribution they have made to the grand picture of the museum!"

"They're just kids!" Sudo Kirihiko shouted.

"So what?" Ryu Sonosaki put his hands behind his back and looked at him flatly.

"I'm not going to let you get away with it!" Sudo Kirihiko immediately took out his memory.

【nasca！ 】

"Tell me, what can I do to save that girl?" Sudo Kirihiko asked, placing his sword on the neck of Ryubei Sonosaki.

"Just confirm the location of the bird's memory in her body, and destroy it." Ryu Sonosaki put his hands in his pockets and explained casually, "But what do you want to do when you ask this?" ”

"Needless to say, of course it's to save ...... Uh!! Halfway through his words, Sudo Kirihiko fell down without moving the Sonosaki Ryubei guard, still relying on the support of the long sword to barely lie on the ground.

"It's ...... What's going on......" Kirihiko Sudo pressed against his chest in pain.

"Kirihiko, you seem to be very unwell, huh?" Sonosaki Ryubei sighed in disappointment, "Although the ability of super high speed has reached lv.2, it seems that this is your limit?" ”

"Could it be ......" Sudo Kirihiko squeezed out a few words with an ugly face.

"That's right, you're also one of our guinea pigs, in order to solve the mystery of NASCA's memory!" Sonosaki Ryubei nodded lightly, "Your body is no longer good, and you're going to die soon!" ”

"Nani ......"

"It's painful, isn't it?" Ryu Sonosaki smiled and took out his memory, "Then I'll free you right away!" ”

【terror！ 】

"The number of family members is going to decrease again, what a cruel thought! Hahahaha! Sonosaki Ryubei couldn't see it at all and laughed regretfully.

As he laughed maliciously, a realm of fear gradually unfolded, and the dark mire of fear spread to Sudo Kirithiko.

"Super, ultra-high!" Seeing that danger was imminent, Sudo Kirihiko endured the pain in his body, gritted his teeth and launched a super high speed, disappearing into this underground ruin in an instant.

"Hmph...... miku！ Ryu Sonosaki smiled absently, waved his hand and sent out the executioner fat cat Miku of the museum, while he himself picked up the bird memory that Sudo Kirihiko had fallen and returned to Sonosaki's house.

And just before the two of them started, there was also an accident in Shotaro's office.

Because he went to report to the barber shop owner that he was safe, there were only two weak chickens in the office, Yashuzi and Philip.

So after Xiao Qian, who was originally asleep, woke up under the influence of Gaia's memory toxin, she directly broke through the barrier of the two of them and rushed out frantically.

Fortunately, Philip installed a positioning transmitter on Xiaoqian when he was popular, so that Shotaro could know her location, and hurriedly set off to track it.

And Xiaoqian, who escaped from the office, was like an addict under the influence of the side effects of the memory, and was aimlessly looking for the bird's memory, when a familiar woman appeared in front of her again.

"See you again, little sister!" Sonosaki smiled and took out the bird memory that Sonosaki Ryubei had given her.

Akane, who had regained the memory of the bird, walked down the street in a distracted manner, and Shotaro quickly followed the tracker to find her.

"Xiaoqian, go home quickly!"

In the face of Shotaro's request, Xiao Qian's answer was a Gaia memory.

【bird！ 】

"Why did it get into your hands again!" Shotaro was surprised.

"That woman gave it to me!" Xiao Qian laughed uncontrollably, and the memory was inserted into her arm, "So that I can fly again!" ”

"It's a great feeling! Hehehaha! Akane, who turned into a birdman dopant, spun in circles with a satisfied face.

"Ah!! How so! Shotaro cursed angrily at the person who gave the memory to Akane, and reluctantly put on his belt.

【joker！ 】

【lone！ 】

"Transform!" x2

【lone！ joker！ 】

"Do you want to play with me?" Xiao Qian, who was already excited, smiled and shot countless flying needles at Shotaro, and then flew into the sky and quickly moved away.

Seeing this, Shotaro had no choice but to summon Revolgarry, then drove the motorcycle up, and switched the rear half of the body to a small red fighter body, which is the flying form of the motorcycle hardboilder, the hardturbuler.

Just as the two begin a thrilling aerial chase, Sudo Kirihiko is also being chased by Miku's saber-toothed tiger Dopant.

The original speed of NASCA's memory was not as fast as Smilodon, not to mention that Sudo Kirihiko's physical condition was not good now, and he was at a disadvantage from beginning to end, and he was quickly beaten back to his human form.

“miku！ Stop it! Just when Miku was about to kill Sudo Kirihiko with one claw, he noticed that the two of them were fighting, and Wakana Sonosa, who chased him all the way from Sonosaki's house, opened his mouth and shouted.

Miku was stunned for a moment when she saw her, but it was obvious that the orders of the Sonosaki Ryubei were higher than that of Sonosaki Wakana, and its figure paused before rushing towards Sudo Kirihiko again.

"Tsk! Don't you even listen to me?! "Sonosaki is angry.

【claydoll！ 】

"Bang!"

"Meow-"

A ball of energy hits Miku's body, and Miku screams and turns back into a cat, crawling back to Sonosaki's house.

Sudo Kirihiko finally exhaled and sat down on the ground.

"Brother-in-law Kirihiko, where is your usual high-minded appearance?" Lifting the transformation, Sonosaki Wakana looked at the embarrassed Sudo Kirihiko and teased.

"Ha, thank you, Wakana!" Sudo Kirihiko didn't care either, and laughed bitterly.
