Hundreds of thousands of meters is hundreds of kilometers, this is not an underground passage to run all, the ground is full of hard dirt and rocks, and even harder metal ores, maybe there are even more terrifying deposits. For most people in Tyrande Big 6, the underground is a mysterious and unknown world, and even those powerful legendary powerhouses don't know much about the situation in the Big 6 underground.

Not to mention that this mining area is extremely mysterious, shrouded in magical magical powers, and no one can predict what will happen underground.

After Mu En merges, he can cast the "Earth Walking Technique", which is probably the only way to go down to hundreds of thousands of meters underground, but he still faces a big problem. His earth-walking skills could not be sustained indefinitely, supporting him to hundreds of kilometers deep underground.

The standard movement distance of this spell is five kilometers, which means that as long as you successfully cast this spell, you can advance at least five kilometers underground, of course, the mage himself, bloodline, and equipment bonuses will have a certain impact on the final effect, and if you want to continue to advance underground, you must spend a lot of mana, and the magic power of the same magic can only support the earth's magic to continue to advance about two kilometers.

All spells have this problem, if you want to forcibly increase the power of a third-level spell to level four or five, then the mana you consume will increase dramatically, so it is rare to see a mage forcibly raise a low-level mage to a high-level spell, and if Mu En wants to cast a low-level spell to reach the ground, it will consume a lot of mana.

Of course, Mu En obtained the epic equipment of "Endless Magic", and it happened that a few days ago, Mu En stored a lot of magic power in it, and now it seems that it may be able to be used.

But the more important issue is that Mu En's "Earth Walking Technique" must be guaranteed to be in a state of integration with Xiaobei. The duration of the merge is not only related to Kien's magic power, but also affected by many factors such as Kien's physique, level, and mental power. Judging from the last time Mu En used the "Earth Movement Technique" to break through the blockade of the barbarian army, it was very remarkable that he could advance thirty kilometers underground at a time.

So if Mu En really plans to go underground now. He could only divide the long journey into many sections. But the ground is full of dense rock and soil, and there is no room for Mu En to rest, he will be squeezed and suffocated to death by the dense rock and soil, which is really a kind of aggrieved way to die.

The control of the air is not a problem, but there must be enough resting space underground, otherwise the terrifying underground pressure in the depths is also unbearable for Mu En, especially when I heard that the excavated soil in this place will reappear out of thin air, and the further down you go, the faster it will recover!

Looking for a monster that can burrow quickly?

Thinking of this, Mu En's heart suddenly moved, and he vaguely remembered that when he was in the underground world, he had caught an underground demonic beast that was very powerful.

His consciousness sank into space, and with the help of Xiao Ling, he really found the demonic beast. The second-level "dark spotted mouse", it was precisely because of the movement caused by this demonic beast attacking the caveman tribe that Mu En appeared in the tribe of Ra, and now he and his brother can eat the food made of mushroom wheat every day, although it has little effect, but it can also gradually change the magic physique of several people every day, which is a good thing that even many divisions can't enjoy, maybe after a while, everyone can become an elite mage.

In the introduction to the Warcraft Illustrated Book, it is said that this kind of Warcraft drills holes very quickly, and can even drill extremely in metal, and Mu En used the enslavement contract to control the dark spot book rat and then tested it in the dimensional space. This kind of demonic beast's ability to make holes is indeed very terrifying, if it is in the ordinary underground, not to mention one Muen, even if it is ten Muen. This dark spotted mouse can also create enough space for them in a minute or two.

No wonder there are so many Warcraft that can make holes, and there is no separate introduction to the hole-making skills of these Warcraft, but the hole-punching skills of the Dark Spotted Beast alone are written in the Warcraft Illustrated Book.

However, this kind of monster is very rare in the terrestrial world. In the underground world, it is rare to be caught because of their ability to drill holes, and it is lucky that Mu En can catch this guy.

However, the dirt that is dug up in this magical place will be filled up quickly. In order to ensure stability, Mu En gritted his teeth and used the little remaining power essence in the space on this dark spot technique. After the second-level Dark Spotted Rat was upgraded to Level 3, it did not grow much in size, but its ability to burrow became more terrifying, nearly four times faster than that of the second-level Dark Spotted Rat.

How deep the ground is, those scholars didn't have a letter at the beginning, but it will take more than twenty days just to go, and it is very inconvenient to use the earth movement technique when he comes back, so Mu En found a way to drag Edwin to send a magic message to Audrey, saying that he needed a teleportation scroll.

The portal spell is a master-level spell, and the teleportation scroll is a very precious thing for ordinary people, but for an epic mage like Audrey, he just needs some relatively precious materials, and Audrey even hopes to advance to the legend is on Mu En, how can he be reluctant to have a teleportation scroll.

Two days later, after Audrey took the time to deliver the teleportation scroll, he encouraged Mu En a few words and left in a hurry.

Mu En simply explained the matter to Nehwal and the others, and then escaped underground with Xiaobei.

Twenty-five kilometers underground, Mu En felt that there were still a few minutes to unfit the state, and he was afraid that it would be too late to release the dark spotted rat from the space in advance, only to see the third-level dark spotted rat turn into a gray-black breeze, and quickly slash its claws around Mu En to send those dirt to its mouth, and in just two minutes, an underground space about ten meters long, five meters wide, and four meters high was formed, if it was a second-level dark spotted rat, it would be much slower, and only a quarter of the space could be planed out in the same time, and the essence of Mu En's power was still worth the money。

Mu En observed that the space that had been dug up was indeed shrinking rapidly with the naked eye, and after about twenty-four hours, the space would be completely covered, and it would only take a few more hours for the dark spotted rat to dig up again every few hours to ensure enough space.

It took a full five minutes to summon the dark spotted rat from Mu En, and Mu En's merger state was naturally lifted, which made Mu En secretly regret that if he continued to move forward with the Earth Movement Technique, he would be able to advance at least five kilometers or more.

I don't know how deep it is to reach the ground, and Mu En can only perform the Earth Movement once a day, if it is five kilometers a day, then twenty days will be a hundred kilometers less, and he will have to stay underground for a few more days.

Therefore, Mu En decided to accurately record the time of each merger and the time it takes for the dark spotted mouse to dig out a small space for one person from the next day, and make full use of every minute of the merger.

Alone in the underground Muen, it is okay to be idle anyway, so he decided to learn the new enchantment formula "Mage's Gift" obtained at the birthday party, this enchantment scroll has been in his space for a long time, if he can make Zuò successfully, his staff's bonus to magic will be greatly increased, and it will also help him go deeper into the ground faster.

Although he is only an intermediate mage, he has a very high talent in enchantment, and now he has been able to make high-level enchantment scrolls "Magic Source" is proof, of course, every enchantment formula is extremely complicated, and every learning a "enchantment formula" is a headache, not to mention that this "mage gift" in Mu En's hand is a high-level enchantment formula, and it is an extremely rare double-effect enchantment.

After a night, Mu En's brain was burned so painfully, and he tried several times but failed, and still couldn't master this enchanted scroll, but he wasn't in a hurry at all, this time he was alone in the underground for a long time, just find something to do for himself, otherwise this kind of boring days will suffocate people crazy.

The next day, he persevered to 29 kilometers, and sure enough, after a minute, he automatically released the fit state.

This night, he still didn't learn the "Mage's Gift" enchantment formula, and wasted a lot of high-level materials, which is really a branch of magic that burns money.

......

For five consecutive days, Mu En traveled a total of more than 140 kilometers through the boring underground and studied the enchantment scroll, and the monotonous life made him feel bored, but fortunately, during the rest of the fifth day, he finally succeeded in making the first "Mage's Gift" enchantment scroll.

It's a pity that his skills are not good, and his skills are not very skilled, and the original high-level double-effect scroll was reduced by him by one level, and the first scroll he made was enchanted on the staff to increase the spell casting degree by 27% and the spell power by 28%.

However, the success of the scroll means that he has mastered the core content of this "enchantment formula", and the rest can improve the effect of the scroll as long as he continues to accumulate experience and proficiency.

Anyway, it's okay, after successfully learning the "Mage's Gift", the joyful Mu En continued to make this kind of scroll, and when the magic power was consumed, he relied on his perverted magic power to restore his magic power, in order to make a better effect of the enchantment scroll, the magic power in the "Endless Magic" ring is used to save his life, and he will not use it lightly unless he has to.

"39% spell casting degree and 44% spell power! Whew!" After more than ten hours of continuous spell making, Mu En also felt extremely mentally exhausted, this scroll in his hand was the strongest increase in spell power, although the bonus of spell casting was a little unsatisfactory, but what Mu En urgently needed now was to increase the effect of the spell, which could allow his earth movement to go further.

A few days ago, Mu En analyzed his own situation, and he roughly estimated that if he didn't count any spell effect bonuses, he would only be able to travel about 22 kilometers in the Earth Movement during the merger period. The primary dragon bloodline can increase the spell effect by 2o%, the combination can increase the spell effect by 1o%, and the effect of the illusory real staff is mainly in its two special effects, and its enhancement to spells is negligible.

If this enchanted scroll is enchanted on the Illusory Real Staff, it will be nearly 1o kilometers more, which may save a lot of time, if only I had known to prepare more magic equipment to increase the power of the spell, Mu En thought secretly.

This is great news for Mu En, who has been bored underground for a long time, and it can save a lot of time. (To be continued!)
