The aura of the earth's evil spirits is not something that can be formed in a day or two, and if this place of gathering evil can be preserved until now, it can be seen that the quality will not be too high, otherwise, the Jindan Elder who regularly cleans the forbidden land of the crypt would have already collected it.

However, even if it is the lowest level of Earth Evil Qi, one will cost thousands of spirit stones, and it has no price, and once it appears, it will attract the attention of the refiner.

Not to mention anything else, when refining a high-grade magic weapon, adding a wisp of earth-shattering qi, it is possible to obtain a rare top-grade magic weapon, and the value is doubled, and a lowest-level earth-shattering qi is enough to refine ten magic weapons.

Therefore, Li Muchen naturally has no reason to give up, not to mention that this gathering evil place has blocked the real lair of the demon lion, and these evil qi alone is enough to make Li Muchen do it.

Taking out a jade box magic weapon from the storage bag, this is a container used to hold high-level elixirs, with a sealing spell, Li Muchen opened the jade box, cast an exorcism method to inhale a wisp of earth evil qi, and the action was very delicate, so as not to cause the outbreak of earth evil.

It is worthy of the fire and earth evil qi, quite violent, and immediately after being ingested into the jade box, it immediately moved, and a burn mark was burned at the bottom of the jade box, which did not look like a dead thing, and it was full of spirituality as if it had its own consciousness.

The spirit of the earth can become an excellent treasure for refining magic weapons, and this spirituality is also a major reason, with the help of its power, it can quickly cultivate the spirituality of magic weapons, thereby strengthening the quality of magic weapons.

The jade box magic weapon used to contain high-level elixirs is mainly used to prevent the elixir in it from withering and sealing the medicinal properties, and it does not have a very good effect on the earth's evil qi, and the earth's evil qi is indeed dangerous.

In a few breaths, this wisp of earthly evil qi completely dissipated, and by the way, he took away a high-grade magic weapon.

In this way, Li Muchen was a little distressed by the loss of a high-grade magic weapon, but there was indeed no more suitable artifact on his body that could be used to contain the earth's evil qi here, and the spiritual weapon-level storage magic weapon in his hand, one was a medium-grade spiritual weapon pure flow bottle of the water system, and the other was a gourd spiritual weapon of the wood system, and the attributes were not suitable.

Of course, if the value is high enough, it is acceptable to charge the Earth Demon at the cost of a damaged spiritual weapon.

Putting away the damaged jade box magic weapon, Li Muchen did not work in vain, through this wisp of earthly evil, Li Muchen also passed its nature, and probably confirmed its variety.

From the point of view of destructive power, it is a second-grade earth evil, the dark fire system, the main characteristic is the spirit devouring - this is the regular attribute of the earth evil qi, with a burning effect, if it can hurt the enemy, penetrate deep into the bone marrow, and maintain its own existence with the help of the enemy's mana, it must be suppressed as soon as possible.

This kind of earth shatter is absolutely an insoluble existence during the qi refining period, and having a magic weapon with this kind of earth shatter is enough to settle down. But when used in spiritual weapons, in the fighting methods of the cultivators in the foundation building period, the effect is not very good, the toxicity is not strong, and the explosive power is not enough, it is difficult to break through the defense of the cultivators in the foundation building period, and it cannot play a key role, it can only be said that talking is better than nothing.

It is very suitable for some fire poison secret arts, which can greatly increase the power of secret arts, and can have a good effect in battle.

There are a few top-grade spiritual weapons on the body, and there is no need to use them to improve the quality of the spiritual weapons, of course, if the amount collected is enough, it doesn't hurt to refine the Burning Star Sword, which can make this high-grade spiritual weapon a little stronger.

What Li Muchen values most is the corresponding secret arts, there are a lot of secret techniques like the Changqing Sect Library Pavilion, and the power of the spell mainly depends on the quality of the earth's evil qi, and the influence of the spiritual root attribute itself is much smaller, which can make up for the shortcomings in the spell.

At least, this kind of secret technique will not be weaker than the ordinary spell cast by a cultivator who specializes in fire-based exercises, and he can take out his hand.

However, the matter of collecting the earth evil has to be considered in the long run, this is the territory of the sixth-order demon beast and demon lion, and if you want to collect a complete earth evil qi, it is impossible to hide the movement from the master here, this time the infiltration time is long enough, and there is a risk of exposure if you take it down, after testing it, Li Muchen dealt with the traces and exited the valley.

There is still time, and the one-month time limit has only passed a quarter, so there is no need to rush forward.

There are only seventy-two Earth Demon Halls and thirty-six Tiangang Palaces, the total number of Ancient Demon Blood Jade is placed here, the Ancient Demon Blood Jade collected by Li Muchen in the Dixuan Hall is equivalent to the normal five halls, and there are sixth-order demon beasts here, if it can be successful, the harvest will not be less than that of Tiangang Palace, there are fifty trial disciples in the entire Crypt Forbidden Land, no matter how you count it, it is also at the middle and upper level.

Therefore, it is better to explore the combat power of the demon lion first and then consider it, if the strength is too strong, you can only get a little bit of the earth evil qi out, if you can kill it, Li Muchen will naturally not miss it, just the earth evil qi is already worth a lot of money, and the demon lion residence behind the gathering evil land must have more treasures.

In terms of the ancient demon blood jade, it is decided, the Dikui Hall has a guardian formation, although the demon lion has a sixth-order strength, it is impossible to attack the main hall, just sneak in, it is still very simple, of course, it is very troublesome to come out after entering, knowing that someone has entered the treasure storage place, the demon lion is not stupid, just wait for the rabbit outside, if you are not sure to repel the demon lion, in this case, it will be a little difficult to escape.

In the next few days, he figured out the law of the demon lion's movements, and the demonic qi emitted by the Dikui Hall was not continuous, there were intervals, and the demon lion's behavior pattern also cooperated with this, and occasionally went out to hunt.

The rest of the time, he stayed in the lair behind the Gathering Evil Lands to cultivate.

During this period, Li Muchen saw the power of the mutated tail of the demon lion, and during the predation of the demon lion, he did not keep an eye on it, but it could be seen from the traces of the scene.

That brute bull demon beast, only the third order, is not enough to force out the demon lion's hole card, but that time the demon lion seems to be in a bad mood, and there is no idea of hiding his strength in front of the low-level demon beast, so he used this trick.

According to the scorching crack at the scene, thinking about it, while improving the Demon Lion's physique, the Earth Evil Qi also gave it this move, and from this crack that was whipped, Li Muchen clearly sensed the Earth Evil Qi.

On the whole, the strength of the demon lion is not too strong, it is estimated that it is only the cultivation of the early stage of the sixth order, except for the mutated tail, other combat methods are very conventional, however, judging its strength only from the predation situation, it can't be done accurately, according to its performance, after overestimating, with the cooperation of the formation and rune treasure, Li Muchen feels that there is still some chance of winning.

No matter how bad it is, he still has a talisman in his hand, which gives Li Muchen a certain amount of confidence.

I gave myself a divination, but I can't see anything, the level is still too low, in addition to the general trend, the general situation is still unpredictable, from this point of view, nothing has been calculated, it means that it will not be too bad, as long as you don't die, you should be able to avoid risks.

So, Li Muchen got busy, and during this time, he had figured out the surrounding terrain, and now he could lay out the layout in advance.
