After entering the seventh carriage, Su Xiao quietly came to the door of the carriage and locked the door of the carriage leading to the front and rear carriages.

Frankie was completely asleep, and in order to ensure that he would not wake up suddenly, Su Xiao took out a needle and injected it into Frankie's back.

Frankie's transformed man is a bit strange, the front of his body has been replaced by a machine, and the back is still flesh and blood.

After making sure that Frankie would not wake up in a short time, Su Xiao untied the ropes and chains on Frankie's body.

Tapping Frankie's chest, the exterior is soft, the interior texture is hard, and there should be a lot of space inside.

Su Xiao was a little embarrassed for a while, how could Frankie's chest be opened, did he want to be violently demolished?

After a careful search, Su Xiao found a switch on Frankie's side ribs.

With the flick of the switch and a click, Frankie's chest flipped open, and three bottles of Coke came into view.

Su Xiao didn't touch the three bottles of Coke, but searched for the inside of Frankie's chest, and after looking for a long time, Su Xiao didn't find anything suspicious.

Grunt.

The Coke in Frankie's chest began to be consumed at an accelerated pace, as if some sort of emergency measure had been activated.

The small half-bottle of Coke was quickly consumed, and Frankie's body trembled a few times, but finally did not stand up.

Su Xiao continued to search, and except for some major organs in Frankie's chest cavity, all other organs were replaced by machinery.

I didn't find what I wanted in my chest, Su Xiao's brows furrowed, the other party's body was so big, where could that thing be hidden?

Pointing his finger at Frankie's arm, he still only perceives the steel structure, nothing suspicious.

The head, chest, arms, and legs Su Xiao all sensed one side, but found nothing.

This made Su Xiao very puzzled, could it be that the thing was not in Frankie's body? Unlikely, according to the intel of the original book, that thing Frankie was carrying with him.

Su Xiao fell into deep thought, if he hid something in his body, then where would he choose to hide it?

First of all, the size of the thing is not too big or small, and secondly, because the thing has been around for a long time, it is easy to break.

It's small and fragile, and the combination of these two points excludes the possibility that the thing is hidden in the arms and chest.

Where is the least likely to be injured during the battle, Su Xiao's gaze looked at Frankie's back.

Pointing his finger on Frankie's back, Su Xiao sensed inch by inch, sensing Frankie's lower back, and his fingers paused.

"What is this?"

Su Xiao searched around there, and soon he found an artificial film disguised as skin.

Lifting the artificial film, a palm-sized combination lock appeared in view.

There are three kinds of passwords, from the number 1 to the number 9, 'A(3,9)=9*8*7=504 kinds', there are 504 combinations of passwords, it is obvious that it can't be opened by luck, Su Xiao began to recall some information.

Tom the Fishman's birthday is March 16.

Iceberg's birthday is January 3.

Frankie's birthday is March 9.

For three birthdays, Su Xiao first tried Tom the Fishman's birthday 316, and after entering the password, the red light turned on and a number 4 was displayed.

This combination lock can be deciphered a total of five times, and after five times, it may lock or self-destruct.

Tom the Fishman's birthday is wrong, Su Xiao thinks about other possibilities.

If he's not mistaken, it's likely that the code is related to Tom the Fishman, who has too much influence on Frankie.

So the password that Frankie set, especially the three-digit one, is likely to be the birthday.

Su Xiao tried the second combination, 313, which is the combination of the month of the three people's birthdays, and Tom's month begins.

The password is still wrong, there are three chances left, Su Xiao tried 331 again, it is still wrong, and there are two chances left.

None of the three combinations are right, and there are two chances left.

Su Xiao left the birthdays of the three of them behind, the password may not be a birthday, or a more important day than a birthday.

More important than birthdays...... Festival Day! Tom the Fish-Man's Day.

Su Xiao had a headache, where did he go to find Tom's sacrifice day, it was really a dog.

At this point, it doesn't work, and he begins to quickly recall everything about Tom the Fishman.

First of all, Tom the Fishman was convicted for helping Roger build a ship, and after being convicted, Tom the Fishman was exonerated for helping the World Government build a sea train, but the World Government did not believe in his words and used other excuses to put Tom to death.

Instead of being summarily executed, Tom was seriously wounded by a gunshot shot and taken to Justice Island to be executed.

Tom was executed in the summer, judging by the clothing of the citizens and the CP department at the time, and it was late summer.

Su Xiao had stayed in the Capital of Seven Waters for a period of time before, and had a first-hand experience of the temperature and climate of the Capital of Seven Waters.

It was late summer, and Tom was sent to Justice Island for execution.

Tom is not a heinous crime, he is just an accomplice, but the matter of helping Roger build a ship is very important, so Tom the fishman will be tried first, and will not be directly executed.

And the execution time of Justice Island will not be arbitrarily chosen, especially the execution of legendary shipwrights like Tom, and the racial conflict between fishmen and humans.

There are already a lot of clues, late summer, the execution of Justice Island, and on the specific date of the execution, Tom's body was sent back to Fish-Man Island for burial.

Su Xiao thought quickly in his mind, and finally pressed 831 on the combination lock.

Click, the combination lock opened, Su Xiao took out something inside, and after checking the attributes of the item, he nodded with great satisfaction, and put something into the combination lock, locked the combination lock, and tied Frankie in his original posture.

Restoring the scene, Su Xiao returned to the roof of the carriage from the window, and the cold rain hit.

Su Xiao lay on the carriage, his upper body was in the air, and reinstalled the glass window, and he also wiped the water stains on the glass window before installation.

After doing all this, Su Xiao walked lightly to the fourth carriage on the top of the carriage, turned over and entered the compartment where he was before, the heavy rain could clean up the footprints he left on the roof of the carriage.

First stripped off the wet clothes, Su Xiao wiped his whole body, threw all the wet clothes and towels into the sea, and changed into the same clothes as before.

He not only wiped the rainwater off his body, but also wiped all the rainwater in the compartment, leaving no fingerprints and footprints.

After doing all this, Su Xiao installed the glass window of the compartment and breathed a long sigh of relief.

Su Xiao suddenly found that Bubutney behind him was looking at him.

"What, hungry?"

"Wang."

Bubuwang is not hungry, it is lamenting that the human world is really complicated.

"Not hungry?"

Su Xiao looked at Bubutney in surprise, he had recently noticed that Bubutney's IQ had significantly improved a lot.

It wasn't so obvious when he first synthesized Bubutney, but as he grew more experienced, Bubutni showed a very different intelligence from the beast.

Although Bubutni is not as intelligent as a human being, he is definitely not stupid, but only two.

"Bubu, how many are these?"

Su Xiao stretched out five fingers, and Bu Buwang's head hung down, as if he didn't want to answer such a mentally retarded question.

"Hey, it doesn't seem too smart."

Bubutney rolled its eyes, feeling that its intelligence had been insulted like never before.
