"Alice, help me see what that glimmer of fire is, can it be used by me?" Qin Feng asked Alice in the sea of knowledge.

Although Qin Feng was the creator of this "martial arts" world in his previous life, in the face of this world that has become more and more deviated, Qin Feng suddenly found that in this world, there are still many things that he, the author, does not know - this ...... What a painful realization!

"This ...... It should be the remnant of the 'Void Black Flame' - this fierce bird should have entered the birthplace of the Void Black Flame by chance, found the breath of the Void Black Flame, and then used its own energy as the medium, which contained this trace of the 'Void Black Flame', this thing...... Amazing!" Alice said with some amazement after thinking for a moment.

"Void Black Flame?" Qin Feng asked in amazement, "What is that?"

"Void Black Flame, according to legend, is the flame born from the first ray of darkness at the beginning of heaven and earth, with unpredictable divine might!" Alice gave Qin Feng a visual metaphor after pondering for a while, "If you sell this trace of Void Black Flame to this system, you can directly get 50,000 years, and if it is this trace of fire on the Void Black Flame Original, you can directly exchange it for 500,000 years in the system, and if it is a complete Void Black Flame, the value is really incalculable- At the current level of the system, it is estimated that you will not be able to exchange for such 'high-end goods', and you will have to upgrade the system two or three more times, in that case...... I guess that's it!"

"Two or three more upgrades?" Qin Feng couldn't help but complain angrily to Alice in the sea of knowledge, "Ten thousand years at a time, two or three more times, then it will take another twenty or thirty thousand years?"

"Uh...... Wrong!" After hearing Qin Feng's words, Alice said with a somewhat wry smile, "Ten thousand years is only the amount of time needed for the first upgrade, and when you upgrade the system for the second time, the amount of time required at that time should be twenty thousand years, and the third time...... It's 50,000 years - that is, even if you get the full 'Void Black Flame', you have at least 70,000 years to upgrade the system first, and then ...... Seven hundred points of system integration can not be less, so ...... Master, you have to continue to work hard and continue to work hard to earn time!"

"Oh my God!" Qin Feng couldn't help but sigh, "You might as well kill me with a sword!"

"Master, the system has now been upgraded to one level, therefore, the system's 'trading mall' has also been opened, you can take this opportunity to do business and earn time, there is no need to just rely on simple tasks in exchange for time like before!" Alice kindly reminded Qin Fengdao.

"I want to, too, but ...... In this hellish place, I have to find someone who is willing to do business with me first, right? You don't know that the few people who survived this trial are still avoiding me in order to 'pass' my useless 'ghost catching props' - if it's somewhere else, it's a big deal to kill them directly to do business with them, but now in this dangerous 'Dragon Roar Valley', I can't go on a rampage and forcibly arrest them, right? Don't catch them at that time, but attract some powerful existence, in that case, it will be too much to gain and lose. Qin Feng said very helplessly, after all, in this dangerous and abnormal ghost place, God knows what the "consequences" of impulsiveness will cause, so ...... It's better to move forward obscenely and develop obscenely!

For Qin Feng, in this "Dragon Roaring Valley", it is too much to restrain him, and when he and Mu Shuiqing leave this place, it will really be a dragon entering the sea - when that time comes, Qin Feng is confident that he will let Mu Shuiqing reach the level of "Emperor Realm" in the shortest possible time, and he, Qin Feng, will also follow closely and catch up with his Qing'er in a shorter time.

"That'...... Master, this 'Void Black Flame', you ...... Do you want to sell it?" Alice interrupted Qin Feng's deep groan and asked cautiously.

"What do you think...... Should I trade it to the system or should I raise it myself for a while?" Qin Feng consulted Alice's opinion.

"Uh...... To tell the truth, this 'Void Black Flame' is indeed a rare treasure, but unfortunately, this 'Void Black Flame' is not pure, it is just a fire light nurtured by the breath of the 'Void Black Flame'...... Compared to the owner who already has black gravel, there is really no value in cultivating it anymore - after all, this trace of 'Void Black Flame' breath has been contaminated with its qi because of the relationship between being nurtured by that fierce bird, master, you insert it halfway to continue to cultivate, although its growth space is still huge, but ...... But it will never be possible to really condense it into the flame in the darkness at the beginning of heaven and earth!" Alice carefully analyzed for Qin Feng and said, "Instead of continuing to cultivate this 'Void Black Flame', the master should devote himself to cultivating those black gravels! You know, if these black gravels can grow to the top, although they are not as good as the 'Void Black Flame' in their complete state, their potential is far more than this trace of miscellaneous fire at the moment!"

"That'...... Just redeemed it?" At this time, Qin Feng still felt a little pity, after all, the predecessor of this glimmer of fire, but the flame born from the first ray of darkness at the beginning of heaven and earth, turned it into time like this, and always felt ...... Some are reluctant.

"No hurry!" Unexpectedly, Alice, who let Qin Feng exchange this trace of firelight, stopped Qin Feng's direct exchange behavior, and then, in Qin Feng's somewhat puzzled expression, Alice slowly explained, "Although the growth space of this trace of fire is not top-notch, but in terms of its current energy, it is still somewhat useful for you, the master-before exchanging it for time, you might as well squeeze all its remaining value to avoid waste!"

"That'...... Will squeezing its surplus value affect its final exchange value?" Qin Feng asked with some hesitation.

"Of course not!" Alice gave Qin Feng a reassuring answer.

"That'...... What should I do now?" Qin Feng couldn't help but ask Alice curiously—for such a big flash of fire, Qin Feng wanted to know its residual value...... How far can it go!
