The "buzzing" sound was the sound of Wan Jian Coffin trying to seize these swords, and the swords resisting. ¡°Oh, it would be great if we could give birth to a weapon spirit. Baotian couldn't help but sigh, if there was a weapon spirit, the power of the magic weapon would be doubled. At least when facing the enemy, he won't be so stubborn. As soon as Bao Tian thought about it, Wan Jian Coffin changed his strategy according to his thoughts. The black light still enveloped the entire sword tomb, but the fight for the swords changed to one by one. Come one by one, pick the soft persimmons first. It is indeed impossible for the Wanjian Coffin to deal with that spiritual weapon. It is also a bit tricky to deal with the top-grade magic weapon, but it can deal with other high-grade magic weapons first. Let¡¯s start with the third-grade magic weapon. Black Light is like a shameless thief who specializes in stealing from the old, weak, sick and disabled. As expected, this move was done beautifully. The sounds of "swish, swish, swish" sounded one after another, and third-grade swords were constantly being sucked into the Wanjian Coffin. This is no longer something that Wan Jiancoffin can accomplish independently. Baotian is basically controlling the entire process. Bao Tian was distracted and said to Tang Xiao and Jin Feng Yuan: "Exit first. Don't enter this cave unless I call you." Both Tang Xiao and Jin Feng Yuan knew how powerful they were. The sword coffin was in time, but they were afraid that they would have been injured by the vertical and horizontal sword energy. Now they both saw that Baotian was fighting hundreds of swords. Tang Xiao and Jinfeng Yuan could not help, so they had no choice but to obey Baotian's order, and one person and one ape exited the cave. go. With the two of them gone, Baotian no longer has anything to worry about. He simply sat down cross-legged and concentrated on controlling the Wan Jian Coffin to collect the swords one by one. After collecting all the third-grade swords, Baotian immediately forcibly controlled the Wanjian coffin to withdraw the black light. The coffin lid automatically closed with a "snap", and then there was a violent vibration inside, as if it was trapped inside. The beast was struggling to get out. As soon as the black light was withdrawn, the sword energy that had just been restrained was released again. At this time, Baotian had already released circles of golden flames. This spell had been named [Nine Yang Fire Lotus] by him. Fire overcomes metal. The sword energy was completely restrained by the Nine Yang Fire Lotus, and was smelted without a trace at the slightest contact. At this time, the worst swords on the sword tomb were all second-grade swords. Now that he had gained some spirituality, he knew that Baotian was powerful, so he didn't dare to use his sword energy on him anymore. Naturally, the Nine-Yang Fire Lotus that covers the sky cannot last indefinitely, so I accepted the Nine-Yang Fire Lotus. Unexpectedly, while Yu Wei was still there, there was no sword energy coming back. At this moment, Baotian controlled the Wanjian Coffin and began to refine those third-grade swords. You must know that there are at least hundreds of swords trapped in it, so it must be a protracted battle. I don¡¯t know how long it took, but the violent vibrations in the Wanjian coffin became weaker and weaker. Finally, there was no movement at all in Wan Jian Coffin. At the same time, Baotian could clearly feel the changes in Wan Jian Coffin. Weird patterns began to appear on the Wanjian coffin. The patterns were so mysterious, profound, grand, and ancient that even Baotian couldn't identify them. The lines seem to be sketched out on their own, extending and changing bit by bit. But it only covers one corner and that's it. Then Wan Jian Coffin suddenly expanded with a "whoosh" sound. It was originally just a small iron coffin the size of a palm. Now it was four feet long and two feet wide. It had grown several times and it really looked like a coffin. . This is not just an increase in body size, Baotian can clearly feel Wan Jian Coffin's joy - Wan Jian Coffin has been upgraded! After devouring hundreds of third-grade swords, the Wanjian Coffin was finally directly upgraded from a top-grade magic weapon to a spiritual weapon! Although it is only the lowest level ninth-grade spiritual weapon, a spiritual weapon is a spiritual weapon, and the best magic weapon can be shattered simply by relying on level oppression. Baotian couldn't help but be overjoyed. He had originally thought that the Wanjian Coffin could be upgraded, or that it was more than just a magical weapon, but now it turned out to be true. He was also worried that the Wanjian Coffin would not be able to break through the spiritual weapon. After all, there was a huge gap from the magical weapon to the spiritual weapon, so it would be so easy to break through. In fact, it¡¯s not easy. If he hadn¡¯t encountered this sword tomb, God knows when Baotian would have been able to collect hundreds of third-grade swords to supplement Wanjian Coffin. Most importantly, this is just the beginning! Baotian hurriedly swallowed a marching pill, not planning to rest, and wanted to work hard. He once again controlled the Wan Jian Coffin to release black light. After the upgrade, it was no longer black light, but now black light. Although it is still dark, it looks much more domineering. Moreover, Baotian can feel that the power of this black cloud is definitely ten times that of the black light. Heixia is much thicker than Black Light. It looks like an upside-down waterfall. It rolls towards the sword tomb with a "boom". This time it is really menacing!  Without saying anything else, he first rolled up all the second-grade swords. At this time, those second-grade swords were just a piece of cake and had no ability to resist at all. But after the coffin board was closed, these second-grade swords realized that something was wrong and began to resist desperately. The Wanjian coffin began to tremble again, but it was not violent at all. The level of suppression was here. Next is another long refining process, but this time the time is much shorter than the last time. Although there were hundreds of second-grade swords, Wanjian Coffin was no longer what it used to be after upgrading its spiritual weapon. Baotian felt much more relaxed. When the second-grade swords were completely refined, Baotian saw that the strange lines on the Wanjian coffin began to automatically outline again, but it seemed that the energy was not enough, and this time it extended to one corner and stopped. However, the Wanjian Coffin is a little bigger, reaching five feet in length. Naturally, this is not just an increase in size, Baotian knows that Wanjian Coffin has been upgraded to an eighth-grade spiritual weapon at this time. Bao Tiantian was overjoyed. It had been a long time since he got the Wanjian Coffin, but it had always been a top-quality magical weapon and he had never been able to break through. Gradually, he felt that it was no longer as useful as the Fire Dragon Rope. But I didn¡¯t expect that Wan Jian Coffin would now have a second life. If you don¡¯t upgrade it, it will be upgraded to three levels in a row. Is there a rhythm? Baotian was so excited that he couldn¡¯t even take a break and continued working. Controlling Wan Jian Coffin, he began to collect the first-grade swords, but this time he was disappointed by Baotian. He could feel that Wan Jian Coffin was very powerful, but he could not continue to break through. Unwilling to be reconciled, Baotian continued to struggle. After collecting all the top-quality swords, the Wanjian Coffin was finally upgraded this time. He grew up a foot and was upgraded to a seventh-grade spiritual weapon. It seems that this spiritual weapon is getting harder and harder to upgrade as you go up, but Baotian is not giving up. Now he only has the last spiritual weapon sword left. If he keeps this spiritual weapon sword, he might still be able to upgrade it. . ??????????????? Originally, Wan Jian Coffin¡¯s attempt to shake this spiritual sword was simply a dream. However, after devouring so many swords and upgrading them to seventh-grade spiritual weapons, the Wanjian Coffin was even higher than that spiritual weapon sword. Although the height is limited, high is still high. It can be cleaned up, it just takes a little more work. After Hei Xia was released, he started a fierce fight with the spiritual weapon sword. Bao Tian obviously felt that it was a bit like a dragon and tiger fighting. The spiritual weapon sword "buzzed" and the sword mound made of stones was shaken. It shattered, rock dust flew everywhere, and even the underground stone walls were cracked with several thick ravines. But after all, the spiritual weapon sword is weak alone, and Wan Jian Coffin has Baotian as the behind-the-scenes commander, who is of a higher level. It didn¡¯t take long for the spiritual weapon sword to be forcibly pulled into Wan Jian Coffin. "Bata!" Wan Jian's coffin lid was heard, like an impatient old bachelor who lured a little girl into bed. And the fierce struggle of the spiritual weapon sword in the coffin of ten thousand swords can be described as an old bachelor tearing the little girl's clothes on the bed. The little girl refused to obey, and the old bachelor was so hungry and thirsty. In short, even Bao Tian, ??who was watching maliciously, was breaking out in a cold sweat. It turns out that this spiritual weapon sword is called [Qingzhi Sword], and it is an eighth-grade spiritual weapon. Fortunately, Wanjian Coffin has now been upgraded to the seventh level, and finally, with a slight advantage, he was able to bow the Qingzhi Sword to the Overlord. When the Wanjian Coffin was successful, the entire coffin was buzzing with joy. The coffin boards were opening and closing like an old bachelor who had succeeded and was grinning from ear to ear. At the same time, the Ten Thousand Swords Coffin grew to an adult size of eight feet long and three feet wide. The jet-black coffin board, with its weird and obscure lines and rigid edges and corners, all exudes domineering power. Baotian was also happy from ear to ear. Although Wan Jian Coffin failed to break through in the end, he still maintained the level of the seventh-grade spiritual weapon. But with his strength, Baotian believed that it was definitely a low-grade spiritual weapon that could walk sideways. What a crow¡¯s mouth, Baotian couldn¡¯t help but complain that he was thinking of getting promoted to three levels in a row before, but now he was promoted to three levels in a row. If I had known earlier, I would have planned to upgrade to four levels in a row, no, five levels! Baotian happily checked the contents of Wan Jian¡¯s coffin. He was really pleased. This hard work was finally worth it. Now there are 540 third-grade swords, 320 second-grade swords, 109 first-grade swords, and thirty top-grade swords in the Wanjian Coffin. There is an eighth-grade spiritual weapon, the Qingzhi Sword, which is really a great harvest! ?????????????????????????????????????????????????????? out of the Green Poison Sword, Qiuhong Sword, and White Rainbow Sword in the Wanjian Coffin, Bao Tian didn't even look down on it, and simply didn't bother to hear their names. What makes Bao Tian even more overjoyed is that the second level of restrictions on Wanjian Coffin has been opened! Baotian got the Ten Thousand Swords Coffin, and just after refining it, he realized that the Ten Thousand Swords Coffin had six levels of restrictions in total. The first level of restriction is to swallow sword-like magic weapons. Then again and againI couldn't open the second level of restriction, but unexpectedly it was opened naturally at this time. "The second level of restriction is exactly what Baotian can use, and that is the fusion sword formation. Baotian originally chose the "Nine Yang Jue" and "Flying Fire Meteor Sword Formation" from the Fazang Pagoda. He had already practiced the Nine Yang Jue, but he had never been able to master the Flying Fire Meteor Sword Formation. Baotian¡¯s original idea was to use the swords in the Wanjian Coffin to practice the Flying Bolide Sword Formation. He thought that the conditions were met, but who knew that it would not work. He thought he had made a loss-making deal, but he didn't expect that it wasn't the Wanjian Coffin that failed, but the restriction that hadn't been opened. Now that the restriction has been lifted, the powerful technique of the Flying Fire Meteor Sword Formation can finally be practiced. So Baotian started a new round of retreat. He was eager to integrate the Flying Fire Meteor Sword Formation and the Wanjian Coffin. In fact, the main reason was that he still had powerful enemies outside. Abaoji is very powerful, and Abaoji enters the realm very quickly relying on swallowing. When he came in, Abaoji's strength was comparable to the legendary realm. Who knows how powerful he is now? Baotian is not worried about Tang Xiao. Tang Xiao and Jinfeng Yuan are together, and there will be no chance of their opponents in the entire underground tomb. Moreover, Tang Xiao was already in the early stage of the psychic realm, and his lifespan could reach two hundred. Baotian was not worried about being in seclusion for a long time. He saw that Tang Xiao had turned into a middle-aged woman
