"I know the first-level wind blade scroll, but what is this spirit-level experience pill?" Lin Feng looked at the green round pill pattern, and he didn't know for a while, so he didn't know what this spirit-level experience pill was for?

However, listening to this name, he had a faint guess in his heart, although it was not necessarily correct, but it should not be far from his answer.

"Spirit-level experience pill, taking one can increase 10 million experience points. ”

Sure enough, seeing this information, Lin Feng knew that he had not guessed wrong, this spirit-level experience pill was really used to increase his experience, but he was a little surprised, he never thought that just one pill could increase 10 million experience points, and if there were a hundred pills, it would be 1 billion experience points, and this 1 billion experience was beyond his expectations.

In other words, this time, he not only got nearly 1 billion experience points by killing monsters, but also obtained 1 billion experience points from the items he obtained, a total of nearly 2 billion experience points.

By the way, he still remembered that he also obtained a black iron level treasure chest, which has not been opened yet, and he doesn't know what is in it?

Lin Feng took this black iron-level treasure chest out of the backpack space.

I saw a dark box appear in front of Lin Feng, this box was about 50 cm long, about 30 cm wide, and 20 cm high, and the box was engraved with some runes that Lin Feng had never seen before, and he didn't know what the origin of these runes was.

The first moment he saw this box, Lin Feng didn't use that black iron level key to open this box, but was about to do an experiment, he pressed one end of the box with his hand, wanting to see if he could use brute force to open this box.

"It seems that this box can't be opened with brute force, so I can rest assured, even if this box is obtained by someone stronger than me in the future, if he doesn't have the key, he will definitely not be able to open this box. ”

Lin Feng had already used nearly ten percent of his strength, but he still couldn't open this box.

This made him a little shocked, you must know that with the strength that he has reached the Xuanling level realm, with a strength of nearly 5 million catties, if it was an ordinary box, he would have been pinched into powder a long time ago, but now he can't even open this treasure chest, which shows how terrifying this box is.

However, this also shows one thing, that is, without the key, it is absolutely impossible to open this box.

Lin Feng took out a black key from the backpack space, this key was very simple, a bit like the key in ancient times, and the color of the whole body was pitch black, and I didn't know what material it was made of, and the hardness was the same as the black box, and it couldn't be bent by brute force.

"Hehe, if you don't want to be in a hurry to see what is in the black box, it is estimated that it is a good choice to use this key as a weapon, at least the hardness of this key is definitely better than any weapon. ”

Lin Feng played with the black key, thinking about the scene where he used a key that was only about ten centimeters long to kill the four, he was absolutely amused, and couldn't help but shake his head, "But in this way, it is estimated that it will be regarded as a psychopath, how can anyone use a key as their own weapon?"

Without thinking much about it, he directly inserted the black key into the hole slowly, and Lin Feng's heart was also raised at this moment, and he looked at it intently.

With a click, the black box opened, and then turned into a little starlight, dissipating into the void with the wind, leaving only a stack of red runes in its place.

"Ding, the Black Iron Level Treasure Chest is opened, congratulations to the host for obtaining 20 primary experience runes. ”

As soon as he heard this voice, Lin Feng's face suddenly collapsed.

Beginner Experience Charm!

He wanted this to be a fart, and in an instant, the mood of anticipation fell to the bottom, as the so-called greater hope, the greater the disappointment, and his mood at the moment can be described as terrible.

Even if the things in this treasure chest are primary transformation cards, it's fine, but this treasure chest gave him the most rubbish primary experience talisman, what's the use of him coming, he is upgrading by absorbing and transforming the lower grade Xuanyuan stone, and not by killing monsters to upgrade

Wait, killing monsters Lin Feng suddenly thought of something.

By the way, he rarely uses this experience charm in the outside world, mainly because the experience gained from killing those monsters in the outside world is so low and small that he doesn't use this primary experience charm at all.

But now, he has opened the copy function, and there are a lot of monsters in it, just enough to use these experience charms to increase his experience, although the experience increase of the primary experience charm is only 20%, but if you kill monsters to get 1 billion, 20%, then you can get at least 200 million!

It's 200 million once, but what about five? Isn't that 1 billion?

This is only an easy level copy, what if it's a hard level?

How many will there be?

Lin Feng, who had figured it out for a while, couldn't help but feel a little relieved, and his whole person seemed to be much more yang, no longer as depressed as before.

"In the dungeon before, the strength after cultivating the mystical technique is naturally different from the strength after not cultivating the mystical technique, which shows the importance of the mystical technique, it seems that you need to cultivate some other mystical techniques. ”

After putting those junior experience talismans into the backpack space, Lin Feng began to calm down and think about what he still needed to improve, after breaking through to the Xuanling realm, the amplification effect of the exercises was no longer useful to him.

Cultivating exercises, that is just a means to increase your strength in the early stage of cultivation, after reaching the Xuanling realm, no matter what kind of exercises you have cultivated before, there is no increase in strength.

The only thing that can have an amplification effect can only be the Xuan Technique, and only by cultivating the Xuan Technique can the strength be greatly increased.

It's just that now, among the mystical techniques that Lin Feng has learned, there are only the low-level mystical skills of the Meteor Flame and the low-level mystical technique of the Flood Rank of Heaven and Earth Fury, and among the two, only the Meteor Flame has learned the great success, and the Arcane Flame is only a beginner, and he has not even entered the first layer, and he can't use this mystical skill at the beginner stage at all.

"Well, it's just 1000 progress points, if converted into a low-grade Xuanyuan stone, that is 100 pieces, okay, it's not much anyway, I'll take a look at how many progress points are needed to cultivate to the second layer after upgrading?"

Lin Feng opened the character attribute interface, came to the Xuanji column, looked at the progress value of "0/1000", nodded slightly, and 100 lower-grade Xuanyuan Stones were thrown into it like this.

"Ding, Hong-level low-level mystical technique, Heaven and Earth Fury cultivation stage upgrade, current stage, first layer, next stage, second layer, current progress 0/6000. ”

After Lin Feng saw this information, he was stunned for a moment, it turned out that the progress value required to cultivate to the next stage was only 6 times that of the previous stage, and he immediately muttered a little, "It doesn't seem to be a lot, it's okay, anyway, it only needs 600 lower-grade Xuanyuan Stones, which is not a lot for my stock of more than 4,000." ”

Without saying a word, Lin Feng once again put more than 600 lower-grade Xuanyuan Stones into the cultivation of this Xuanyuan.

"Ding, Hong-level low-level mystical technique, Heaven and Earth Fury cultivation stage upgrade, current stage, second layer, next stage, third layer, current progress 0/120000. ”

"What!"

When Lin Feng saw the progress value required by that information, he couldn't help but exclaim, his eyes were in a daze, he never thought that he would need so many progress points to cultivate from the second layer to the third layer.

120,000!

If it was replaced with a lower-grade Xuanyuan Stone, it would require 12,000 pieces, and so many lower-grade Xuanyuan Stones would be enough for him to ascend to the second level of Xuanling.

However, when he saw the six words "Hong-rank low-level Xuanji", he also came back to his senses slightly, how to say that this is also a Hong-level Xuanxuan, and it is reasonable that so many Xuanyuan stones are needed to cultivate to Dacheng.

Looking at the progress in front of him, Lin Feng shook his head helplessly, although he had already understood, but the need for so many Xuanyuan Stones was not enough for his current net worth of three or four thousand.

"It seems that this mystical technique can only be cultivated to the second level at this stage!" Lin Feng said with a helpless sigh.

However, it's okay, if you cultivate to the second layer, your strength can also increase by 16 times, which is comparable to the amplification effect of those who have cultivated the advanced mystical skills of the desolate rank to Dacheng. Lin Feng thought with some self-comfort.

Immediately after, Lin Feng opened the backpack space, and then took out three scrolls.

Needless to say, each of these three scrolls is a cultivation scroll.

The first scroll was a defensive mystical technique, which was originally obtained from the hands of the two elders of Zhao Lengsheng, and it was called the Great Sea Immeasurable!

And the second scroll was a body-type mystical technique, which was obtained from the hands of Sun Yuan and Sun Zhen, the two Xuanling seventh-level elders, called Phantom.

As for the last one, it was also obtained from the hands of the Sun family elders, a desolate mid-level palm type mystical technique, called Broken Mountains and Rivers.

These three mystical techniques are all the mystical techniques that Lin Feng has cultivated at this stage, no matter whether they are good or bad, he plans to learn them all in one go, as the saying goes, many skills are not pressing, and one more mystical technique is always good.

Lin Feng didn't say a word, he directly opened the three scrolls, and suddenly three bright lights flew into his eyebrows at the same time, and at the same time, he also remembered the prompt sound of the system in his mind.

"Ding, I found a low-level mystical technique of the desolate level, did the host decide to learn it?"

"Ding, I found a low-level mystical technique of the desolate level, did the host decide to learn it?"

"Ding, if you discover a Desolate Intermediate Occult Technique, has the host decided to learn it?"

Lin Feng took a deep breath, his tone was firm, and he continued to speak.

"Yes!"
