Although weak, Gus''s five senses are quite acute - perhaps this is the only place where he inherited his father''s martial arts talent.


    When you touch the green brick with your fingertips, you find that there is something strange at the joint. This green brick is a little higher than all the bricks and stones around.


    Fine as a little hair, the naked eye can''t see it. You have to feel it with your fingertips in the most delicate way.


    It''s like this green brick is not firmly embedded in the brick wall, but has been pulled out and put back, but not to the end.


    Gus tried to pull out the brick.


    But the bulge is too subtle, there is no force at all. After several attempts, the nail almost broke, and the brick is still motionless.


    Gus thought about it. He took out a feather arrow from the quiver at his waist, took the arrow as a dagger, and pried it at the joint of the green brick.


    This time, the bricks were loose.


    Encouraged, Gus took out another feather arrow and clamped the green brick from the top and bottom.


    The width of the two fingers was clamped out. At last, there was a place for exertion. Gus grasped the brick with both hands and pulled out more than half of it.


    But then, how to smoke, how to pry, are of no help.


    "It''s impossible. There should be something strange about this brick. There''s no reason to take out half of it!"


    Gus scratched his head.


    He was deeply attracted by his lost sister and strange green brick. He couldn''t help groping for it. After trying more than ten methods, he finally found the trick.


    It turns out that this brick, originally only a thin layer, can be rotated and moved.


    He turned half of the brick three times to the left and two times to the right. After returning to his original position, he pressed it deeply.


    Half of the brick fell into the brick wall.


    Behind the brick wall came the sound of gears and chains turning, extending all the way to the bottom of the training room.


    Then, in the southeast corner of the training room, the floor slid open silently, and a dark hole suddenly appeared!


    Gus was so surprised that he was almost out of his wits.


    It''s not because of the sudden appearance of the underground cave, but because the underground cave is controlled by gears and chains, which are all precision machines!


    "Why is there a mechanical controlled underground cave in our practice room?


    "Well, it''s not my sister, is it?


    "Is it dad? It''s impossible. Dad is the first master in Chijin town. He is the most devout to the God of boxing. How can he!


    "Sister, is sister in there?"


    Gus''s brain is blank.


    Legs but involuntarily open, trembling toward the hole.


    Under the cave is a narrow ladder, which leads directly to the deeper underground. At the end of the ladder, there is a strange light.


    Gus swallowed hard, put an arrow in his palm, and crept to the underground chamber.


    Half way down the stairs, an evil voice came from the underground chamber.


    It''s the gear rotation, the clatter of the chain, and the squeak of the steam.


    Although Gus had never heard of these voices, he had been influenced by his uncle. He had heard them from his uncle. At the moment, they were exactly the same.


    My uncle once told Gus that once he heard a similar voice, he must have found the devil''s lair and the altar of the evil Taoist. He would run as fast as Gus could and report to the temple of boxing.


    But my uncle didn''t tell Gus, what if this "demon altar" was found under his own ground?


    Gus seems to have fallen into one of the most terrible nightmares.


    It is also like being attracted by the mysterious "mechanical and steam force".


    He moved to the end of the ladder step by step and saw the incredible scene.


    This is a very large secret room.


    All around the walls were covered with pipes like the blood vessels and intestines of steam demons.


    A lot of rusty pipes still make a "hiss" noise at the joints, spurting evil steam.


    Countless pipes crisscross, converging into a huge and strange machine.


    There is no language in the world that can describe the horror of this machine.


    It''s like it''s made up of 10000 gears, and it''s also involved in a lot of chains, bearings, springs and components that Gus can''t name - huotuotuo is the devil who climbs out of hell.


    Inside the machine, there are several strange stoves burning, releasing a lot of hot steam.


    Steam through the pipeline transmission and convergence, are severely compressed to the front of the machine, a slightly larger than the heart, inlaid with a large number of rivets and valves on the metal ball.


    And in front of this metal ball


    Gus''s sister, grey, wearing a pair of goggles and greasy canvas overalls, is kneeling there devoutly, chanting evil incantations.


    Though he had already guessed it, Gus''s heart still fell into the abyss.


    My sister is really a believer in the power of machinery and steam.


    Compared with Qin Yi, who has just been burned, her sister''s depravity is only a hundred times deeper. I''m afraid her soul has long been sucked away by the mechanical demon and steam demon.


    What remains in the world is just an evil body.


    Gus is in a dilemma. He doesn''t know if he should escape. He reports to his uncle in time to save his sister''s devastated soul.


    But when he thought that Qin Yi had just been burned into a toad, he couldn''t move.


    At this time, the sister''s words after ending the spell made Gus as numb as lightning.


    "Dad, see? I''ve made it. I''ve found the answer you''ve been looking for all your life!"


    Grey was so excited that she laughed wildly in the shrill sound of steam. "This is the purest steam power. This is the most powerful power in the world, which is superior to all the" fist power. "


    With the last word finished, grey seemed determined to die. She clenched her teeth and hit the metal ball with a hammer.


    "Chi"


    The metal ball gave out a shrill whistling sound, spurting out a thick fog like steam, and in an instant, enveloped the whole secret room.


    Such appalling evil finally broke Gus''s nerves. He screamed and rolled down the stairs into the secret room.


    "Who?"


    Grey was also shocked. Without looking back, she punched Gus like a boa constrictor coming out of the hole.


    When she found out that the intruder was her brother, it was too late for her to stop, "boom", and this blow hit the floor of the secret room, making a hole like a honeycomb.


    "Gus?"


    My sister''s face became very ugly.


    "Sister, sister!"


    The younger brother began to cry in frustration.


    "Cough, cough, cough!"


    Without waiting for the two brothers and sisters to explain everything clearly, there was a strange cough in the deep steam, in the corner of the secret room, where nothing was supposed to be.


    A thin and short figure emerged from the steam.


    "Who!"


    Grey''s eyes widened and her face was shocked.


    No one knows the structure of this secret room better than her. There is no other way out here except for the ladder that my brother fell down.


    How could a third man come out of the deep steam?


    Gus is scared to embrace her sister''s thigh, hiding behind her sister, looking at the "people" in the fog.


    This is a very ugly child.


    At the age of at most six or seven, the hair is yellow and the skin is black. At first glance, it looks like a malformed bean sprout. The over inflated head will break off from the slender neck at any time.


    The little guy seems harmless, but Gus and grey dare not take it lightly.


    Especially when they saw the ugly kid''s feet, they felt numb and couldn''t believe their eyes.


    Ugly kid has no legs.


    From the waist down, his body drags a bunch of rich steam all the way to the strange metal ball.


    It''s as if he''s made of dense steam, coming out of a metal ball.


    Gus thought of the secret rituals of some heretics mentioned by his uncle.


    With a deep shiver, he stammered: "elder sister, you are not calling the ''steam devil''


    "How, how possible?"


    Even if grey was a believer in the power of machinery and steam, she was scared out of her mind by the ugly kid and said, "I''m just extracting the purest power of steam. How can this happen? Hey, kid, what are you


    Grey waved her hammer to the ugly kid she had summoned.


    "Come on, if you have something to say, put down the hammer first. I''m very timid and can''t stand the threat."


    The ugly kid looked around curiously, as if he had never seen such a world before. After watching for a long time, he returned to Gus and grey with a deep look beyond his age. He said with a smile, "although I don''t quite understand what you mean by" steam devil ", I''m sure it''s not that thing. Let me introduce myself. My name is LV Qingchen. What about you?"
