This is one of the important reasons why Li hengxuan didn't smelt the age sword for so long.

At the beginning, the Dragon lost his strength, and now he is not in the world.

"Come on, let's go after him."

Li hengxuan smiles and chases the Dragon forward.

At this time, the speed of time sword is extremely fast, even higher than the general peak of Emperor Wu. He can't catch up without breaking the boundary boat.

But now in the cave world, he has an absolute advantage, does not need to break the boat, as fast as you want.

After a while, Li hengxuan and the magic dragon came to the back of the years sword. At this time, Li hengxuan did not accelerate, but hung far behind the years sword.

He will consume the power of the sword of time.

Although this is in the cave world, Li hengxuan is not afraid of years sword attacking himself. He can use the world power of the cave world to suppress years sword when years sword is used.

But Li hengxuan can't use the power of Dongtian world at ordinary times.

In this cave world, cave world will take the initiative to protect Li hengxuan's safety, but it will not help Li hengxuan deal with other things.

So he will consume the power of the sword of time.

When his strength is exhausted, it is the best time for Li hengxuan to start.

Li hengxuan chased him like this, hanging far behind the years sword, watching the years sword run away. Anyway, he didn't need to consume Xuanqi to fly here.

"I'll see how long you can fly!" Li hengxuan is smiling and confident.

But obviously, he underestimated the strength of the time sword. Until the third day passed, the time sword still showed no sign of slowing down. On the contrary, it became faster and faster.

The Dragon whispered: "master, I think you seem to have a wrong idea. It's just a sword. It doesn't have any burden, but the flight cost is very little."

"No, I'm right. No matter how little it costs, it's also a waste. And we don't need to consume it at all, but I didn't expect its durability to be so strong! "

Li Heng Xuan shook his head and said, "look again."

He chose to wait until the seventh day to see where the limit of time sword was.

Li hengxuan's patience is almost exhausted, and the sword of the years ahead is still flying like that without any sign of slowing down. It seems that its energy is endless.

"It seems that I underestimated the sword."

Li hengxuan sighed in a low voice and said, "it's beyond my imagination. It's hard to imagine who made it into a sword at the beginning, although the casting technique is not very clever."

When he first got the sword, some people didn't look up to the people who melted it into a sword.

It is considered that the refining level is too low to match such good raw materials.

You should know that the raw materials that contain the power of rules have never been found in the whole Kyushu. This is the only piece that Li hengxuan saw. But now he knows that no matter what the method is, he may not have a high level of skill in refining this raw material, but it is a kind of strength in itself.

"It's said that this sword came into being in ancient times. I'm afraid it was the magic weapon of a strong Taoist."

Li hengxuan sighed in his heart.

That era is too far away. Countless brilliant creatures and things in that era are annihilated with time.

This sword has been preserved, and it can't be underestimated.

"Master, what shall we do now? It has awakened the "spirit". I don't think even if I and Jiuyan Xinhuo are willing to fight together, they may not be able to win him. Besides, now Jiuyan Xinhuo is still sleeping in the master's Qihai, and has not really awakened his spirit. "

The Dragon looked worried.

At the beginning, she also vowed that it was very simple.

As sky fire, refining magic weapon is the basic function of sky fire.

But now she knows that, like Li hengxuan, she thought it too simple at the beginning.

In particular, the current state of Jiuyan Xinhuo is the same as that of the sword of these years. They are all trying to awaken the "spirit" without success. They only have some simple self-consciousness. Even, the magic dragon faintly felt that the time sword might awaken the spirit a little higher than the nine flame heart fire.

She then said: "years sword is not nine flame heart fire, the original master can deal with nine flame heart fire with gentle means, because it can coexist. The master can let him grow up slowly in the sea of Qi, so as to integrate the power of Jiuyan Xinhuo first. But the time sword is different. The master wants to refine it into a new magic weapon, so he has to temper the original sword spirit! "

"I know."

Li hengxuan also frowned.

Sword spirit, sword spirit, that is to say, the sword awakens when it becomes a sword, not when it comes to raw materials. Therefore, it will never allow Li hengxuan to melt this sword into the original raw materials to create a pair of boxing.

This is tantamount to erasing the existence of the sword spirit, and the two sides are absolutely irreconcilable opposites."The current situation is that it is impossible to melt the sword without erasing the spirit of the time sword. However, if we use the emperor chopping sword now, it will be very bad for the back."

Li hengxuan frowns. He wants to use the sword to kill the emperor.

Just as he used to merge the "sword spirit" in front of him in the tianjianzong trial cave, he used the sword spirit to suppress the time sword.

Although the original sword spirit and this sword spirit are not the same thing, one is the talent and treasure, the other is the consciousness of living beings.

But both of them are swords, and both of them depend on swords.

The sword spirit who cuts the emperor's sword has a great deterrent to this kind of thing.

It's just that time sword is very different. He intended to wait until the time when the power of time sword spirit was almost consumed, and then he began to chop the emperor sword to wipe out the time sword spirit. This is the best time.

Otherwise, variables are easy to appear.

"Wait a minute. I don't believe that the sword spirit in these years really has infinite energy."

In the end, Li hengxuan decided to wait.

He and the magic dragon are still following the time sword, but they are not close to each other. They want to consume the time sword first.

Unconsciously, seven days passed.

Today, it has been half a month since Li hengxuan came into the cave world, but the years ahead are still the same, and the speed has no trend of attenuation.

The Dragon whispered: "master, you can't wait any longer. Now the situation outside is changing day by day. We can't waste too much time on this sword. If it doesn't work, we'd better wait for the master to step up to Emperor Wu in the future and spend the emperor's disaster. At that time, there will be an essential transformation of the master's spirit. I believe we can take the sword of the years. "
