"Purple Flame Bullet, Desolate Rank Advanced Skill, Upgradeable, Upgrade Condition, One Fire in the Center of the Earth, Current Stage, Beginner, Next Stage, First Layer, Progress Value 0/40. ”

Fire in the center of the earth, what is this?

Sounds like something underground?

Wait, this name seems to have been seen somewhere

Lin Feng frowned, constantly thinking about where he had ever seen this word?

Suddenly, a flash of lightning struck in my mind.

He knew, he knew where he had seen the word.

Without saying a word, I directly opened the interface of the prestige and honor exchange huàn system, looked at the series of patterns, and searched for it.

Sure enough, near the lower right corner of the screen, Lin Feng saw the four big characters "Fire in the Center of the Earth", and there was a pattern like a flame under those four big words, thinking that this was the Fire in the Center of the Earth.

Looking at the amount of XP required to redeem the huàn item, the words "10,000 Fame" and "1,000 Honor" float below the pattern.

"What! 10,000 reputation points!"

Lin Feng exclaimed, 10,000 prestige points! You must know that he has been mixed up for several months, and now it is only more than 90,000 prestige points and more than 1,100 honor points, this is because he has recently made such a big thing, which has greatly increased his prestige and honor, otherwise, it will be even less.

However, with all his savings, he could only buy ten of such things.

It's so expensive!

However, although Lin Feng complained in his heart that this thing was very expensive, but. He finally used 10,000 reputation points to exchange this fire in the center of the earth.

At the moment of success, a fiery red flame appeared in Lin Feng's hand. It was beating up and down, as if it were alive. However, to Lin Feng's surprise, this fire in the center of the earth did not have a trace of temperature.

Then, Lin Feng opened the character attribute interface and lightly clicked the "Purple Flame Bullet" with his hand.

"Purple Flame Bullet, a high-level mystical skill of the desolate rank, can be upgraded, upgrade conditions, a fire in the center of the earth. Current Stage, Beginner, Next Stage, Level 1, Progress 0/40. ”

"Ding, I found that the conditions for upgrading are met, has the host decided to upgrade?"

"Upgrade!" Lin Feng said without hesitation.

Just kidding, if he wasn't here to level up, why did he spend 10,000 reputation points on this thing?

"Ding. The upgrade was successful!"

As soon as this sound fell, Lin Feng felt that the purple flame bullet in his mind seemed to have undergone some changes.

Purple Flame Bullet (Level 1), a low-level mystical technique of the Hong Rank, condenses a purple energy ball on the palm of the hand that is completely different from ordinary energy balls. This ball of energy is not only extremely hot, but also quite powerful.

The content of cultivation is also unchanged, and it is divided into three layers. The first layer can condense a slightly lighter purple flame bullet. The power is 8 times its own strength, the second layer. Condense a slightly thicker energy ball, which has 16 times the power of its own strength, and the third layer, condense a richly colored energy ball, which has 50 times the power of its own strength.

What the!

50 times?

When Lin Feng saw that last amplification effect, he almost bit his tongue, he was not mistaken, it turned out to be 50 times the power!

Lin Feng didn't expect that just by using a fire in the center of the earth to upgrade an ordinary desolate rank advanced mystical technique, he would actually be able to make the amplification effect of this mystical skill reach the Cheng dù sent by the system, which was really a little surprising to him!

Wait, if he continued to upgrade this mystical technique, wouldn't he be able to get the most powerful Hong-rank intermediate mystical technique, or even the Hong-rank high-level mystical technique?

Thinking of this, even with Lin Feng's state of mind, his breathing couldn't help but become short, and his eyes emitted a blazing light.

Without saying a word, he clicked on the "Purple Flame Bomb" again.

"Purple Flame Bullet, Hong-level low-level mystical technique, upgradeable, upgrade conditions, ten pieces of fire in the center of the earth, current stage, beginner, next stage, first layer, progress value 0/1000. ”

What the!

Ten pieces?

Lin Feng was dumbfounded for a while!

He didn't expect that after the Purple Flame Bullet was upgraded to the low level of the Hong Rank, it would cost ten Earth's Heart Fire to upgrade again, even if he exchanged all his prestige and honor now, he could only exchange it for nine, and there was still such a one, so he didn't bring it to play, right?

At this moment, Lin Feng felt a deep pain!

"Hehe, forget it, wait for a day or two for the prestige and honor to be enough. Lin Feng smiled bitterly and thought helplessly.

Next, Lin Feng didn't hesitate too much, and directly piled those two mystical techniques into Dacheng with Xuanyuan stones.

It's not much, these two mystical techniques cost him a total of more than 600 medium-grade Xuanyuan stones, and for him, it's just a drizzle.

After putting away the things on the table, Lin Feng took out a space bag from the backpack space, all the contents of this space bag were Xuanyuan stones, for the convenience of cultivation, every time he got the Xuanyuan stones, he would get those Xuanyuan stones into a space bag.

Now, there are already tens of thousands of medium-grade Xuanyuan stones in this space bag in his hand, and most of these Xuanyuan stones were obtained by him by robbing the Qinglan Sect, I have to say that robbing this industry is really a profiteering industry.

Without thinking too much, Lin Feng directly took out the Xuanyuan Stones from the space bag and put them in his hand, and began to absorb them.

Ten pieces!

Twenty!

Fifty!

One hundred!

Three hundred!

Unconsciously, Lin Feng had already absorbed eight hundred and ninety medium-grade Xuanyuan stones, and after taking out ten medium-grade Xuanyuan stones again and absorbing them.

"Ding, the experience value is full, congratulations to the host for breaking through to the fifth level of Xuanling. ”

A warm current instantly gushed out of his heart and poured into his whole body, and a sense of comfort made Lin Feng sigh involuntarily, and the fatigue of his whole body also disappeared completely at this moment, and the spirit of the whole person reached the peak state.

After upgrading, Lin Feng did not pause in his hand, and directly took out ten medium-grade Xuanyuan Stones from the space bag again and absorbed them.

One hundred!

Five hundred!

A thousand!

Fourteen hundred, fifteen hundred, sixteen hundred, just as Lin Feng had absorbed the sixteenth hundred, suddenly, there was a dinging sound in his mind again.

"Ding, the experience points are full, congratulations to the host for breaking through to the sixth level of Xuanling. ”

At the moment when this voice sounded, Lin Feng once again felt the warm current that was both familiar and unfamiliar in his body, and the bones of his whole body crackled, and a sense of strength followed.

After experiencing the pleasure of the upgrade, Lin Feng did not pause, and once again took out the Xuanyuan stones from the space bag in his hand and absorbed them

Time passed little by little.

I don't know how long it took.

Suddenly.

"Ding, the experience points are full, congratulations to the host for breaking through to the seventh level of the Xuanling. ”

At this moment, Lin Feng knew that he had absorbed 3,200 mid-grade Xuanyuan Stones, and his cultivation was also Cheng Dù (to be continued...... who had broken through to the seventh level of Xuanling)
