Finally, when Mu Lei was dying, maybe he couldn't even look at the sky, suddenly there was a loud thunderbolt on the sunny sky, and a thick lightning bolt slashed into the body of the demonized lava fire dragon. The demonized lava fire dragon was struck by lightning and trembled, and threw Mu Lei out at once, Mu Lei's blood boiled at the moment when he was electrified, and Mu Lei, who was already dying, had been completely restored to his spirit by this lightning. At this moment, the volcano suddenly erupted, and then the temperature of the magma instantly melted all the ice. A sky of water vapor covered the entire volcano. Hot magma flows down the slope of the volcano. The whole mountain, as well as the lava-burned one, had turned red. Mu Lei had already felt the temperature of the earth in the air. However, although Mu Lei survived at this time, his injuries were still serious. However, Mu Lei's own repair ability is also extremely powerful. As long as you find a place to recuperate, it won't take long to recover, but now there is hot magma everywhere, which makes Mu Lei have nowhere to hide. Besides, there is also a demonized lava fire dragon that I don't know where it is now, maybe the lightning before split the demonized lava fire dragon and injured it, and now I don't know where to recuperate. Or maybe it's hiding and preparing to sneak up on you. So Mu Lei had to keep holding in the air. Mu Lei wrapped himself in an elemental phalanx, and then began to slowly recover his physical strength, vitality, and injuries with returning to his roots. With Mu Lei's current injury, it will take a long time to recover. Unless there is a breakthrough.

In this way, Mu Lei persisted for a day and a night, and the next morning, the demonized lava fire dragon suddenly flew up from the volcanic mountain mouth, and the demonized lava fire dragon broke Mu Lei's elemental phalanx with a dragon swing of its tail. Mu Lei was repairing when he suddenly shook, his elemental phalanx was broken by the demonized lava fire dragon, and Mu Lei immediately flashed away, after all, Mu Lei's own injuries were not healed, and Mu Lei didn't want to swing his tail in the magic dragon of the demonized lava fire dragon.

Seeing that Mu Lei flew to his left again, the Demonized Lava Fire Dragon immediately turned his head and sprayed a flame at Mu Lei. The power of this flame seems to be more powerful than yesterday's, Mu Lei didn't dare to greet it and had to flash away again, but this time the demonized lava fire dragon already knew that Mu Lei would definitely dodge, so this time the demonized lava fire dragon shot a red light wave with his eyes in the direction of Mu Lei's flash. Mu Lei saw the red light wave coming towards him and immediately released a move of the light of destruction, originally the power of the light of destruction could completely overshadow the red light wave, but Mu Lei did not even exert half of the power of the light of destruction because of his serious injury, so the red light wave overshadowed the light of destruction at once, and the red light wave instantly shot Mu Lei's right arm through a hole. Now Mu Lei's entire right arm is basically useless. But this is not the end of it, the demonized lava fire dragon immediately flew over and crashed into Mu Lei when he was injured. Mu Lei knew that he was not the opponent of the Demonized Lava Fire Dragon at all, so he had to choose, dodge, but the speed of the Demonized Lava Fire Dragon was too fast, although his fast shadow flash was very fast, but after all, the physical strength consumed by the fast shadow flash was not ordinary, and now Mu Lei's physical strength was almost to the limit. It won't last long. However, even if Mu Lei doesn't grow for long, Mu Lei will continue to hold on, if he doesn't hold on, then there is only a dead end.

Finally, Mu Lei's physical strength was exhausted after an hour, and he was no longer able to cast a quick shadow flash. And the demonized lava fire dragon was still at the same speed, and it was extremely fast to load it to Mu Lei. Mu Lei had no choice but to take out the Flame Battle Dragon Sword and prepare to fight hard in the end. However, even if Mu Lei is in his heyday, he is not necessarily the opponent of the Demon Lava Fire Dragon, not to mention that Mu Lei is now at the end of the strong crossbow.

Just when the demonized lava fire dragon was about to hit Mu Lei, suddenly the earth in front of Mu Lei cracked, and then a fiery red light shot out from the ground, this fiery red light suddenly shook the demonized lava fire dragon away, and then a long sword slowly rose from the ground to the ground, it turned out to be the Flame Sword (Flame Sword, one of the four major artifacts in the legend, with endless divine power, power can destroy the world, of course, it depends on the strength of the user), Mu Lei held the Flame Sword with his right hand that had been abolished。 I don't know why the right arm, which was already unable to move, was able to understand when the Flame Excalibur came out, and he didn't feel the same way at all.

The moment Mu Lei held the Flame Divine Sword, Mu Lei's body instantly returned to its peak state, and it broke through to level 171. Mu Lei tightly grasped the handle of the Flame Divine Sword, feeling the power that could destroy the world and destroy the world. Mu Lei integrated the power of his five elements and the power of the Flame Divine Dragon into the Flame Divine Sword. Unleash a move with all your might, and the Five Elements Wandering Dragon slashes towards the demonized lava fire dragon. The power of the Five Elements Wandering Dragon Slash was amazing, instantly splitting the demonized lava fire dragon into pieces and finally destroying it in ashes.

Mu Lei didn't expect the Flame Divine Sword to be so powerful, and it was able to completely kill the Demonized Lava Fire Dragon in an instant.

Now that Mu Lei has also obtained the source of the five elements, he has also obtained the Flame Divine Sword, and he has also improved his strength, and now it is time to go back. Mu Lei wanted to go back to King Ling Mu and them first, mainly because Mu Lei had asked Ling Muyun, and Mu Lei hadn't solved the demand for a long time. But Mu Lei thought about it in a blink of an eye, even if he went back, he might not find them. Let's go find the rest of the treasures first. It is said that the Extreme Ice and Snow Valley is in the northernmost part of the continent, and there must be treasures there in the place where the Divine Fire Phoenix once lived.

Mu Lei immediately decided to go to the Extreme Ice Valley. Mu Lei used the sword technique to fly quickly in the direction of the Extreme Ice and Snow Valley. Now Mu Lei's strength has increased, and his speed has naturally improved. Now Mu Lei's speed with the sword technique has reached a very fast speed. In particular, the speed of the Flame Excalibur was even faster, and it took less than 10 days to reach the Extreme Ice and Snow Valley. There was no danger along the way, although he encountered a lot of flying spirit beasts, but because Mu Lei's speed was too fast, he couldn't catch up and had to give up. In this way, Mu Lei came to the center of the Extreme Ice and Snow Valley. However, Mu Lei didn't expect to be able to meet the four ancient demonic beasts here.
