Just as Lu Ban was thinking, the glowing strange thing gradually dimmed, and the old man's suspended body fell to the ground gently. Lu Ban saw that the old man was still closed, so he waited patiently. After a long time, the old man opened his eyes and felt that he had indeed absorbed some vitality, and he couldn't help but laugh twice. After that, the old man said to Lu Ban with a little joy: "Master Lu, you have a total of six woods for this strange thing, and just now one wood resonates with me, this may be the biggest opportunity in my life, I hope to exchange this wood with me with you." No matter what you want, or what I am asked to do, as long as I have what I have or what I am able to do, I will do my best to ask the master to fulfill it. After speaking, the old man made a bow to Lu Ban.

The old man's actions startled Lu Ban, after all, the old man was a cultivator with great power, and his status was high. After thinking about it again, Lu Ban replied: "The predecessors have a fate with this wood, so I will give this thing to the seniors, just hoping that the seniors can save my family when they are in danger." The old man immediately agreed and gave Lu Ban a bone whistle, "This whistle is my spiritual weapon in my early years, and it has my spiritual imprint." When Master Lu is in danger, this whistle automatically releases the barrier, which can resist the full force attack below the Yuan Infant. When I encounter the transformation period, I can also protect the master for a while, and I will come to the rescue with all my might. "Lu Ban thanked his predecessors. Lu Ban also gave the old man a salute.

The old man waved his hand, "I should thank the master for giving me the opportunity to see the new world." I don't know where this strange thing came from. ”

Lu Ban thought about it for a long time, "At the beginning, I made a toy called Lu Ban Lock, but I don't know what happened, some strange things happened when I was done, and Lu Ban Lock became such a strange thing." ”

The old man didn't delve into it further, "Everything has its own reason for its existence, and the master doesn't have to be entangled." As for the remaining few strange things, I suggested that the master keep them properly and not fall into the wrong hands, and the old man took his leave. The old man said goodbye and left.

Looking at the few strange things left on the ground, Lu Ban decided to keep today's secret and made a lot of preparations just in case. However, Lu Ban still underestimated the attraction of Yuan Qi to cultivators. Once a cultivator who has attained the consummation of the Divine Transformation Stage has absorbed enough vitality, he or she will enter the Nine Transformations Tribulation Period. When advancing to the Tribulation Period, the mortal world will descend on the Three Thousand Days of Thunder Tribulation Void for a period of three days, intended to alert cultivators.

The old man who visited Lu Ban before was a cultivator who had completed the transformation period. With the help of one of the trees locked by Lu Ban, the old man's body contained a sufficient amount of vitality in a few months, and he stepped into the Nine Turns Tribulation Period in one fell swoop. On this day, it was like the end of the world, and the sky was full of terrifying lightning. Ordinary people thought that they had offended the heavens, so they began to organize sacrifices for peace. Many cultivators did not know what it was after seeing the vision of the sky, and those thunder and lightning seemed terrifying but did not have the slightest energy breath, and cultivators above the heartbeat period rose into the air one after another to check it, but they could not come to a convincing conclusion, and could only infer that this vision would not cause harm to everyone.

As the reaction caused by the vision in the cultivators became more and more great, some of the great powers who lived in seclusion came out of the mountain, and among them there were many cultivators who had completed the stage of incarnation. These strongest practitioners of the present generation have an uncontrollable restlessness in their bodies when they see the vision of the sky, a situation that has not occurred in their hundreds of years of practice. These powers began to communicate with each other through sound transmission. "Could this be the Heavenly Thunder Tribulation of the Forging Body, but isn't the vitality gone, how can there still be a cultivator of the Tribulation and the Three-Step Void Immortal". "This is an illusion, it should be someone who has been promoted to the Tribulation Period by some means. "Could it be that the Metaverse is real, and now it has reappeared? "If the Metaverse appears, why can't we feel the vitality, this person must have obtained the vitality from some external object. ”............

The appearance of the suspected Yuan Qi has injected a booster into the entire world of cultivators, and everyone is looking for clues about the Yuan Qi. Eventually, the Luban lock surfaced. For the sake of Lu Ban's safety, the old man warned all the cultivators not to endanger Lu Ban and his family. Because they were the first to enter the Tribulation Period, under his warning, many cultivators did not dare to be strong against Lu Ban on the surface, so they had to outwit them in private. After this incident, the strange thing "Luban lock" flowed into the world in a scattered way.

Over the past few decades, the mystery of Luban's lock has gradually been solved by many practitioners. Luban locks are made of ebony wood and are divided into six yuan wood, which are gold yuan wood, fire yuan wood, water yuan wood, earth yuan wood, yang yuan wood and yin yuan wood. The six-element wood itself contains wood attributes that harmonize the five elements of yin and yang, but not every practitioner can resonate with the six-element wood. Liuyuan Wood only resonates with cultivators with the same attributes as oneself, and only with one practitioner for a period of time, unless the practitioner dies or is the cultivator's heir. Wood attribute cultivators can't resonate with the six-element wood, but they can obtain a small amount of the six-element wood's vitality.

After a few more years, some people suddenly wondered what would happen if the six-yuan wood merged. By chance, the six cultivators who held the six-yuan wood came together, but no matter how hard they tried, they couldn't synthesize the Luban lock. The most successful one was the combination of three pieces of six-element wood, and as a result, everyone was instantly fanned out by an invisible force. Some people say that this is the power of the mortal world, and that those who do not want the practitioner to get out of its grasp. There are also people who say that Liuyuanmu has consciousness and is resisting the merger. And more people think that the six-yuan wood is related to the disappearance of the Metaverse, thinking that it is a lock, locking the Metaverse outside the mortal world, and it is also a key, and the moment the six-yuan wood combination becomes a Luban lock, it can open the door of the Metaverse. In the thousands of years since then, cultivators have tried everything to make the six-element wood merge, but they have all failed. Gradually, the vitality generated by the six-element wood became less and less, and all the cultivators had no hope that it would be able to merge, and from then on, the six-element wood gradually disappeared into the world.

Slowly, with the passage of time, the cultivators basically chose to hide in the red dust rivers and lakes, no longer participating in secular disputes, and no longer seeking opportunities to become immortals. Fast forward to the 90s of the 20th century. One day, a family surnamed Ji living in an ancient courtyard in the imperial capital gave birth to a child, and the whole courtyard was filled with a joy. The child was lying on the small bed specially prepared by the family, and the old man placed an old-looking wooden block with some shiny, which was out of place with other things. The old man's cloudy eyes brightened from time to time, as if expecting something to happen. As the minutes passed, the old man was slowly disappointed, but soon relieved. "It's good that nothing happened, so it's safe. The old man muttered to himself. Then the old man gathered his family and said, "This child is called Tianyu, as for that piece of wood, it is about to become a mortal wood, so stay by Tianyu's side, after all, this is also handed down by the ancestors." Then the old man dismissed everyone, and came to the child's side and muttered, "Tianyu, as the descendant of our Ji family, no matter what difficulties you encounter in the future, you must believe in yourself, the road ahead may be difficult, but you must not turn back, you must insist on going on, great-grandfather believes that you can do it." With that, the old man got up and left. At this moment, the wood block, which had not been unusual for decades, emitted a faint light.
