Most of the monsters that can stay in the desert city today are here for the secrets of the Sea of Death. With such a big movement from the Sand Clan, many demon beasts and human races naturally thought of this aspect. Even if the Sand Clan didn't agree, they still didn't stop the people who were secretly following up.

In fact, they couldn't hide it if they wanted to, because as soon as the mud layer opened, the restless fire attribute spiritual power overflowed, and the temperature around them was a little hotter than before. This is a bit of an anomaly, and after a long time, it will still be noticed by all parties.

Shi Yu had already prepared for the demon beast to come over, but they never expected that this wait would be three days.

For three days, they tried every way they could think of to get out of here, but it was all in vain. It's like a separate space that has been carved out, and they're completely locked in, and even the Void Breaker has no effect.

At the same time, they heard the movement overhead clearly.

Around the cave, those demon beasts killed very vigorously. And it seems that there is a steady stream of demon beasts joining the battle, and from time to time there will be demon beasts falling into the cave, and the dead will be rolled into ashes by the tongue of fire, and those who are not dead will just struggle a little, and soon follow in the footsteps of the former.

Seeing too many demon beasts falling, Shi Yu's heart also rose little by little.

The reason can't, the heavenly fire in this cave seems to be gradually recovering after devouring the corpses of those demon beasts. The only thing that remains unchanged is that the Zhendao Sword is still nailed to it, preventing it from breaking free.

But this is not the way to go.

After the sound of fighting outside the cave gradually subsided, the moment a demon beast probed into the cave, Shi Yu immediately made a decision, quickly rushed to the center of the heavenly fire, and pulled out the Zhendao sword.

Even if she didn't pull out the Zhendao Sword, the demon beasts outside would kill them. In that case, it is better to end up.

As soon as the Zhendao sword came out, the heavens and the earth were together, and the earth cracked and the mountains collapsed. The heavenly fire burst out in an instant, and it consciously stretched out the tentacles of the fire, and wherever the basic flames went, everything was annihilated with it. This power is stronger than that of the three fire spirits.

Even if Shi Yu and the others were wrapped in fire spirits and swept up by the fire waves, they still spat blood from their mouths, not to mention the demon beasts at the entrance of the cave that were not protected by fire spirits.

The screams were endless, and the demon beasts that won the struggle outside only became the rations of Tianhuo in the end.

And what made Shi Yu and them creepy was that Tianhuo seemed to be eyeing them. After devouring dozens of demon beasts in one go, a pair of eyes appeared in Tinder, staring at the Zhendao Sword deadly.

In order to defend against the demon beast, a very fierce demon was released. I don't know if this choice is right or wrong.

"It's afraid of the sword. Yue Huan stepped up and said, "This Tianhuo was injured by the Zhendao Sword, so it shouldn't be able to recover so quickly." If we reinsert the Zhendao Sword, there may be a glimmer of life. ”

"I'm afraid it won't be so stupid as to let the Terrans hurt it again. Lin Fan shook his head.

Shi Yu handed over the Zhendao Sword to Lin Fan and said, "You are good at using swords, you can wait for the opportunity." You don't necessarily have to reinsert it, even if it hurts a few points. ”

She's already figured out that they'll be able to run one by one later.

As soon as Lin Fan took over the Zhendao Sword, he felt strangely that his saber actually resonated with the Zhendao Sword.

He took out his saber and looked at it, and both swords glowed with red and blue light at the same time. His heart moved, and a thought faintly came to his heart.

"Maybe the two swords can become one. "This is the message that his saber sends to him.

Shi Yu knew that Lin Fan's weapon was a sealed divine weapon, and the Zhendao Sword was also a divine weapon. If these two can be combined into one, does it mean that they will have a higher probability of dealing with Tianhuo?

"It's a pity that my current cultivation is not enough. He barely used the secret method to ascend, and at most he could only ascend to the sixth layer of Returning to Truth. This requires at least the realm of the seventh layer to fuse the two soldiers.

What's more, it will take time to fuse the two soldiers.

After he took out the saber, Skyfire was noticeably more agitated. I'm afraid that Tianhuo won't give him too much time.

The atmosphere was silent for a while.

Tianhuo is still devouring demon beasts there, and its state is getting better and better, and several people can feel it. They are like young animals trapped in a cage, and they can only be slaughtered.

"Cultivate for me, I can help you improve. Su Fanyin, who had never spoken and even looked like a transparent person, suddenly spoke, "I have a secret method that can transfer my spiritual power to you, and it can probably help you improve your cultivation to the next level." Is it enough?"

"One layer?" Lin Fan thought for a moment, "It should be enough." ”

"If your cultivation is enough, how long will it take you to fuse these two swords?" Shi Yu asked the next question.

"A quarter of an hour. Lin Fan wasn't very sure.

"A quarter of an hour ......" Shi Yu groaned, and immediately took out all the spirit stones she could use from the storage bag, "You guys start quickly, I'll drag it out." ”

They can't beat it, and the only thing they can do now is drag.

The spirit stone flew out in an instant, and the formation immediately took effect, and the brilliance flashed, and the formation was completed in the blink of an eye. This is the first time that Shi Yu has used such a fast speed to form a formation, and the speed is so fast that the face and heavenly fire can't catch it, and the spirit stones of the hidden spirit are automatically hidden.

After the first layer of formations was arranged, Shi Yu quickly laid down the second and third, and basically threw out all the formations that could delay time.

"Do you have the Demon Beast Neidan and the Spirit Stone? The higher the level, the better, take them all out. ”

In an emergency, even if others are distressed, they also know that they can't be stingy. Beigong Hongzhu and Yuehuan were very cooperative, and as soon as these things came out, they were quickly consumed by Shi Yu.

However, the cave, which can accommodate more than 100 people, is surrounded by dense hidden formations. And Tianhuo seemed to be in front of them on the surface at this time, but it was really about to break out, but it was actually far away.

Throwing the last formation out, Shi Yu's heart was relieved, and the person was completely paralyzed to the ground.

Hundreds of formations were thrown out like this, and it was the first time she was so bold. However, the benefits are also obvious, her spirit has broken through, and at the same time, the control of the formation is more handy.

The only thing to see now is whether you can leave here alive.

"It's kind of weird. "As the formation separated the heavenly fire, the temperature around it was not as hot as Fang Cai. Pumping space, Beigong Hongzhu looked at Su Fanyin, who was passing on the gong to Lin Fan, but saw that something was wrong.

Both of them had their eyes closed, and their breaths had merged into one. However, Su Fanyin has become old at a speed that is visible to the naked eye.

Shi Yu also looked over, Su Fanyin's hair had begun to turn gray now. Then, the skin became shriveled. The signs of her life were gradually fading as her spiritual power wore away.

Shi Yu hurriedly fetched the vitality spring water and gave it to her, but it only eased for a while, and then continued to grow old as before.

Feeding the spring water again has no effect.

Lin Fan was unconscious of all this. Only the three people next to her watched her grow old little by little.

When Su Fanyin turned into a white-haired old woman, she gradually opened her eyes.

"You ......" Beigong Hongzhu opened her mouth, but she didn't know what to say.

"With me, you can't go. Su Fanyin shook her head, "This is the only thing I can do now." ”
