One of Rubeus's hands is an ingenious robotic arm, and the amazing thing is that although it is made of machinery, it is extremely flexible. Pen, fun, pavilion www. biquge。 info is equipped with a variety of gadgets on top of the robotic arm, which can be retrieved at any time with different functions.

Spitfire's gaze was fixed on Rubeus, but the focus was on the surroundings.

Originally, it should have been quite dark underground, but above the dome where the waterwheel was located, several wide small holes were dug.

From above, sunlight is refracted in various ways and finally transmitted into the underground space.

"Can I take a look around first?" Spitfire said, and Ruber just nodded, "Just don't mess around with anything here!"

"Don't worry, I'm with you!" Qingling interjected very appropriately, "I won't let Brother Feihuo touch the mechanism!"

"If it weren't for being too stubborn in some ways, she would be a very clever and well-behaved girl. Spitfire thought as he swept his gaze around.

Feihuo looked around, the space around him, about ten zhang square, three or four zhang high, except for the top of the finely chiseled rock wall, the other walls should be chiseled through and built with fine stones.

Behind the surrounding walls, there are supposed to be other rooms, but there is no prominent entrance on the walls except for the one in the power room, which has a door.

Looking at the masonry on the wall, it should have been many years, and if what Lu Bo said was true, it was very likely that this space would have existed before Tang Beiyi came.

Or in other words, there is another "paradise" underneath the entire island.

This may explain how he avoided Pei Gang and was transferred to his room.

And the mysterious entrance before may be one of the entrances to the underground space.

"Can I go to the power room?"

Spitfire turned to ask Rubeus behind him, and Ruber stopped what he was doing slightly, threw out a string of copper keys, and Spitfire took it firmly in his hand.

"Let the girl help you open it, there's nothing to see in it!" Ruber seemed to have a little opinion on Spitfire, and thought to himself, "This kid doesn't seem to be interested in my tricks, what the hell is it for?"

Qingling hurriedly stepped forward and said with a smile: "Then I'll take my brother in!"

Feihuo and Qingling walked to the stainless steel gate, which was also three zhang high.

Beneath the gate, there was a small door for people to enter and exit, locked by an eyed brass lock, and a mechanism wheel with the characters of the sexagenary branch engraved on it, apparently a combination lock.

"This power room is very important, because many mechanisms on the island rely on this drive, so you can't enter without a secret order, if you forcibly open the lock, it will trigger the mechanism behind the door, but I've seen what the trigger looks like!" Qingling carefully inserted the key in, and then fiddled with the password on it.

"Because this basement was there before, there was no large-scale renovation, so I had to make slight improvements to the power room and water wheel to prevent possible damage to Xiaoxiao!" Qingling looked up at the beam on the dome, and then continued to look down and flick the code disk.

"Actually, this password is changing at any time, but only a few people know the method of decryption, and I also begged Lu Bo to tell me, this method of solving the puzzle is related to the hour!"

Qingling whispered: "Now should be Xin Shenshi, so the heavenly stem chooses "Xin", and the earthly branch chooses "Shen", which is one of the passwords. Then, look at the year, the year of the non, the heavenly stem chooses the non, the earthly branch chooses the child, this month is the month of the sunflower, the heavenly stem chooses the sunflower, the earthly branch chooses the mao, today is the day of Ding Chou, and the natural selection of Ding and Chou. ”

"But that shouldn't be a difficult rule, right?" Spitfire thought for a moment, "It's easy for someone to guess!"

"Then Brother Spitfire is wrong! There is also an important count here, the password disk has to be tossed five times in total, does Brother Spitfire know anything about the last count?" Qingling looked at Spitfire slyly, waiting for Spitfire to tell her the last count.

"I guess, if it's only known to people in the Tang Sect, it's nothing more than something in this other island!" Feihuo looked at the trap wheel, and there were sixty options for each count, if it was fixed, it shouldn't correspond to the previous changes.

But if anything, it's something that's on the island. And it's the kind of one that doesn't need to be manually adjusted, so the change of numbers should meet what rules.

Spitfire needs one more condition to be able to determine what the last count is.

Qingling tilted his head, waiting for Feihuo's answer, and when he saw Feihuo's serious appearance, he interrupted him slightly, "If Brother Feihuo wants to guess, I can give a hint, but I won't tell you, what is the answer!"

"Hour, year, month, day, these four all represent the time of the day, and the law of change can be set, so the last one, if the rules are consistent, should be related to the previous numbers, right?" Feihuo asked, but Qingling shook his head, "Then it's good to set four, and the fifth one doesn't need to appear!"

"The rules are set according to my father's opinion!" Qingling reminded with a smile, "As for the rest, Brother Spitfire still needs to guess!"

"Tang Sect Master?" Feihuo recalled Tang Beiyi's person, meticulous and neat, and the last count had nothing to do with the previous ones, conforming to the time of day, and had nothing to do with the days ahead.

Feihuo silently recited the "time of the day" in his mouth, and suddenly thought of a count that only changes every year, but conforms to the time of the day, which has nothing to do with the previous numbers, but is related.

"It's your father's age!" Feihuo blurted out, only this one will change with time, but if you don't know Tang Beiyi's birthday, you definitely don't know the last count.

Qingling's eyes widened, looking at Feihuo incredulously, this young man's intelligence is also rare in the world.

"You, how did you guess!" Qingling almost cried out in excitement, almost grabbing Spitfire's arm and jumping up.

"My dad is eight out of forty this year, and the last count is Xin Wei!"

Feihuo smiled confidently, this level naturally couldn't be difficult for him, but without Qingling's prompt, he would never have thought that it was about the age of the sect master, and this kind of thing is estimated to be only known by the Tang Sect.

"If you hadn't reminded me, I wouldn't have known, since it was your father who set the count, it naturally had something to do with him, and the only one who obeyed the time of heaven was probably only age!"

He stepped forward, toggled the last count, and then reached out and flicked the key to the door, which he slowly pushed open.
