With the two holes in the rock wall, looking at the Dragon extraordinary in this scene, I couldn''t help moving slightly. The size of the hole coincided with the key box he just took out.


    "It seems that this should be the keyhole."


    Long Bufan thought so and saw Yang Liya take out two hexagonal key boxes, one red gold and the other gray.


    In the center of the red gold key box, there is a sun totem, while the gray white key box is a moon sculpture.


    "The key box is divided into yin and Yang. Red gold is Yang and gray is Yin. Only when the two attributes of yin and yang are integrated can the rock wall array be started."


    With a smile of joy on her lips, Yang Liya put the two key boxes into the hole, and then her slender fingers gently pressed the sun and moon totem in the center of the two key boxes.


    "Pa ~!"


    With a soft sound, the key box suddenly opened slowly and automatically like a machine. Then, six triangular pieces were displayed from the edge of the key box, emitting two obscure energies of yin and Yang.


    After a few breaths, the rune array on the red rock wall suddenly moved faster and faster, and flashed a bright red light.


    The original red rock wall was also slowly sunken under the surprised eyes of long Bufan and others, revealing a hole more than two feet high, and even a red staircase slowly extending to the depths of darkness.


    Obviously, what appeared in front of long Bufan''s eyes was that the exit of historic sites and treasures had been completely opened.


    "Success!" Yang Liya glanced at Yang Yu and their beautiful eyes flapped with uncontrollable excitement. The legacy of the Yang family has been inherited for hundreds of years. Today, it is finally a complete return to the family.


    As long as she has this resource, her family hopes to revive, and there is no need to decline and lose the face of her ancestors.


    Looking at the dim hole, five people and a mink were ready to go, but long Bufan suddenly stepped down, and his spiritual consciousness suddenly extended to the rear.


    "Be careful!"


    Immediately, the dragon''s extraordinary mind suddenly flashed a cold air. After drinking, his body jumped more than ten feet away from the side like a spring.


    "Whoosh!!!"


    Just as long Bufan''s body bounced away, the roaring wind sounded at the silent cliff. Then, dozens of iron arrows with cold awn burst out from behind as fast as lightning.


    Those iron arrows are different from the arrows used by the army. They are extremely large. Each iron arrow is as thick as an arm, like a spear, and contains amazing yuan force fluctuations.


    With such a fast iron arrow and a sneak attack, although long Bufan can react in time and avoid, the four people, Yang Liya, Yang Yu, black tiger and Eagle nose, do not have the reaction ability accumulated by long Bufan in countless bloody battles.


    The fierce arrow shadow spread all over the world, Yuan Li rushed, and finally enveloped the four people.


    "Ah ah...!"


    Several screams rang out one after another. Yang Yu and the four of them were shot through their bodies by an iron arrow or their heads were shot and exploded. They died on the spot. Their death was extremely miserable and fell in a pool of blood.


    The rest of the failed iron arrows went deep into the ground, and the dark tail of the arrow was exposed outside, shaking hard under the aftershock of power.
