Lin Lei, who was working overtime, traveled to another world holding a mouse. As a result, Xuantian Mountain where he was at this time was suffering from the disaster of annihilation. At this time, the cross-border weapons arsenal was accidentally activated. Just use items from other worlds to exchange for powerful weapons! Embedded in the soil is the magic weapon used in the Nascent Soul stage - Qingfeng Sword. What is used to roast the chicken is the magic weapon used in the Yuanying stage - the deep sea cold iron spear. Sitting under the buttocks is the magic weapon used in the Yuanying stage - the Five Elements Kaishan Seal. There was even a magic weapon used in the transformation stage - Wentian Ruler, which he used to stir the fire. Seeing that the barrier of the consecrated beads was about to be broken, he was seriously injured. The weapon I exchanged is too powerful and I can't use it. What should I do?
