Naturally, even if it''s an alliance, it''s inevitable to calculate with each other.


    Therefore, Han Zhuoling and Shi Xiaoya entered together, and the gatekeeper did not stop them.


    After entering the room, you can see that there are two doors on the three walls of the room, which is a total of six doors.


    At this time, a light beam shines on the stone platform in the middle, and a figure in a black robe, whose face is covered by a hat, appears in the light beam.


    "Hello, adventurers." The voice of the man in black sounded.


    Obviously after a change of voice, with mechanical and overlapping husky voice, "welcome to the gate of the earth. There are six doors, but only one is the right exit. Only by finding the right exit can we get to the castle. Otherwise, you will be stuck here forever. Forever. "


    I know it''s fake. It''s arranged by the program team. But in such an environment, I will be nervous.


    "So now, you have an hour to save yourself." The man in Black said, "good luck, adventurers."


    The black robed man disappeared with the light beam. Shi Xiaoya looked at Han Zhuoling, "what are we going to do next? I''ll do what you say. "


    "I''ll see first." Han Zhuoling said.


    But han zi Zi looked around for the bright light. Maybe he could not find anything in the room


    "Good." Shixiaoya looks at it and goes to the table not far away.


    There are four treasures of study on the desk.


    There are some words on the paper. Shi Xiaoya can''t guess any clues from the words, but he thinks it''s useful and takes them up.


    I found a seal in the drawer and put it away.


    Han Zhuoling checked every door, and between each door, he took the footstep as the measure of length.


    "That''s all I found." Shi Xiaoya gives Han Zhuoling everything she finds.


    "It shouldn''t be too difficult, because there are other guests, so we can''t eliminate all of them." Han Zhuoling said.


    Director: --


    It''s not true.


    "It''s this door." Han Zhuoling said.


    "How can you be sure?" The director couldn''t help asking.


    "Every door has the same pattern, the pattern of every door is in the same position, only the pattern of this door is slightly offset." Han Zhuoling teased, "when your program team is customizing, do you want one of the doors to be slightly different, so that your program team can identify it?"


    Director: --


    In fact, when they set this level, they also referred to the students of the five elements and eight trigrams, and also calculated through various mathematical formulas.


    However, in order to make it easier for the staff in their program group to recognize it, don''t forget it wrong. They installed the wrong door, so they deliberately hid something different.


    But the correct answer for the guests is not that the pattern is not in the right position!


    In the first issue, Han Zhuoling had all kinds of mathematical formulas at his fingertips.


    Who knows that this time, people will not take the route of learning hegemony, but directly find the most simple and crude point.


    "Is it a hint on this paper?" Shi Xiaoya gives Han Zhuoling the clue she just found.


    "This is the ancient way of mathematical calculation. At that time, neither the Arabic numerals nor the Western formulas had been circulated. We had our own way in ancient times. " Han explained.
