When you're immersed in something, you never feel the passage of time anymore.

At first, Lu Fan just wanted to crack this rune space, but with the study, Lu Fan slowly immersed himself in this rune space, he never thought that the rune could still be used like this.

Half a month's time is fleeting, Lu Fan has been sitting on the edge of the rune space for half a month like an old monk, not even eating, just looking at this rune space fixedly.

Occasionally, he would raise his right hand and gesture in the air, at the beginning, Lu Fan's gesture was like a mortal writing in the air, there was no difference at all, but slowly, occasionally some fiery red lines appeared under Lu Fan's hands, if you look closely, these lines are somewhat similar to those lines in this rune space.

It's just that at this time, the rune lines under Lu Fan's hands are still very incomplete, and only occasionally one stroke appears, like a flash in the pan.

When Master Chiyan saw Lu Fan's movements, his heart was full of horror, he was also studying this space, and even, it was longer than Lu Fan's research, although he also had some gains, but he couldn't do it like Lu Fan.

At first, he was still an apprentice because he looked at Lu Fan more pleasing to the eye, and felt that Lu Fan's qualifications were okay, and there was even a trace of gratitude because Lu Fan was willing to help Xiaoying, so he made Lu Fan an apprentice, but now, he even felt that he might be lucky to have Lu Fan as an apprentice.

And with Lu Fan's continuous attempts, the rune lines under his command have begun to become more and more perfect, and some runes have even begun to have some power.

It's just that these runes tend to dissipate the moment the energy fluctuates, and they don't last.

Suddenly, Bai Zhi, who was cultivating, opened her eyes, although this place was full of fire energy, and the water energy was pitiful, Bai Zhi still did not give up cultivation, but just now, she felt that the energy around her body was surging madly in one direction, and that direction was the direction where Lu Fan was.

Bai Zhi could feel it, and Master Chiyan naturally felt it too, and he also looked in Lu Fan's direction.

I saw that at this time, there was a strange line in front of Lu Fan's body, these lines seemed to be cast with gold and fixed in the air, and this was also the source of those energy surges, as if this strange line was a bottomless pit.

Lu Fan, who had already remained seated, also had a hint of joy on his face at this time, and after trying so many times, he finally succeeded.

However, the next moment, the joy on his face turned to horror, and he pushed his right hand, as if pushing a fragile piece of porcelain, pushing the runic lines in front of him to the side.

Boom......

The rune lines were only withdrawn more than a meter away, and a violent explosion occurred, and Lu Fan was at the edge of the rune space at this time, and this explosion also exploded on the invisible barrier, making a dull impact sound.

Lu Fan, on the other hand, was blown up and flew out, and only stumbled up after a while, covering his ears, his hair was messy, and he couldn't even stand on his feet.

"Haha......"

Seeing Lu Fan's embarrassed appearance, the little girl Xiaoying couldn't help but laugh happily.

Lu Fan couldn't help but touch his nose with some embarrassment, if he hadn't reacted in time just now, I'm afraid that even if he didn't die, he would have been injured.

What he had just drawn was originally a rune structure in this rune space, and he hadn't figured out the role of this rune structure until the rune was formed, and he didn't understand that this rune structure could actually attract free energy between heaven and earth.

This was also the reason for his smile before, however, this structure could obviously only absorb energy, not store or use, so when the energy exceeded the limit of what it could bear, it naturally exploded.

To Lu Fan's surprise, the power of this explosion was not much worse than his energy cone, but the energy was more dispersed, which was a bit regrettable, but this kind of means of using rune attacks consumed very little energy, but it made Lu Fan have another trick again.

"Did you find anything?"

Looking at Lu Fan's happy expression, Master Chiyan couldn't help but ask, and Lu Fan had already taken out a bun and a bottle of water from the space button at this time, and gobbled up food into his stomach.

He hadn't felt hungry before, but once he came to his senses, the belated hunger made him feel like he could eat a cow.

After swallowing a steamed bun quickly, Lu Fan felt a little better, but when he heard the master's question, Lu Fan was also a little embarrassed, because, although he knew all the runes in this rune space.

But the basic rune structure composed of these runes was basically unknown to him, let alone had any effect.

After more than half a month of research, his only gain was that he found that the original rune could also be used in this way, not only could it be engraved on the material to become a rune weapon, but it could also generate a rune array out of thin air for battle.

"The structure of these runes is too complicated, I still can't figure it out for a while, but I have some clue now, as long as I am given time, I will definitely be able to crack this space, Master rest assured."

At this moment, Lu Fan's heart is full of confidence, a good start is a success, although this rune space is extremely complicated, but as long as he is given time, he can completely study it, and at the same time as cracking this space, his progress is also huge, which also benefits him immensely.

"Okay, you don't have to be too anxious, but in the days to come, you can follow me to learn some methods of using flames, and don't pull down your cultivation while studying."

Master Chiyan seemed to be so calm forever, nodded lightly to Lu Fan, and didn't say anything, he didn't try to attack the invisible barrier again these days.

Bai Zhi glanced at Lu Fan, and stopped talking, but after seeing Lu Fan excitedly falling into this rune space, she finally swallowed back the words that went to her throat.

In the days that followed, Lu Fan studied the rune space, and every time Lu Fan studied, some magical lines appeared in his hands from time to time, some of these lines could spit out flames, some could form a layer of ice, and some could summon a gust of wind, and Lu Fan had a lot of fun.

However, this time he did not fall into that state of concentration again, and would spend a lot of time every day learning the use of flame abilities with Master Chiyan, with Master Chiyan's experience, often a sentence or two of guidance would make Lu Fan suddenly enlightened, and it was not even possible to make a surprise discovery.

Previously, because Lu Fan's combat power far surpassed cultivation, the fire ability became less useful, but as his understanding of the fire ability deepened, the fire ability became his killer weapon again.

He also didn't pull down his cultivation, at this time he had already tempered a full fourteen spines, the only thing that made him regret was that he didn't have the slightest intention of breaking through to the three-star entry level, which made him a little anxious.
