Ten days after entering Montenegro, Xu Dao stayed in the cave for ten days.

It wasn't until the eleventh day that he officially left the cave and began to wander among the ghosts of the Black Mountain.

But even when he left the cave mansion, Xu Dao used the Yin God to control the Gu worms to escape, not with his physical body.

The body was placed in the cave by him, and the Gu worms were taken care of, and all kinds of protective measures were used.

Once something really happens, there is a formation and a warning from the Nanke mayfly, Xu Dao will instantly return to the Yin God and return to the cave to protect his body.

At the same time, he also left half of the grasshoppers around the cave, and the remaining half was rolled up and brought out by the Yin God as a means.

Xu Dao ran away, although only half of the grasshoppers were brought out, but their number was as high as 150,000 or 60,000.

And all of them are huge, wasp-like, crowded together, densely packed, and can eat up a piece of forest and grass in a moment.

He possessed the body of a certain mayfly and watched the army of grasshoppers in a clearing far away from the cave.

The flying mayflies hovered him up and down, like a tornado more than ten feet high, and all the plants and trees that were wrapped in it would disappear in the blink of an eye.

It was like a wriggling beast, strange and hideous, and its whole body revealed a feeling of hunger, wanting to eat everything.

This was the first time Xu Dao had seen so many grasshoppers gathered, and he was also shocked and stunned.

But immediately, Xu Dao was overjoyed.

"Such a huge swarm of mayflies should be another powerful reliance on me in addition to the evil qi sword box!"

Moreover, Xu Dao's own cultivation has also broken through to the middle stage of qi refining, and as long as he refines yang qi, he can continue to grow his Dao line.

For a while, Xu Dao was full of ambition.

He thought to himself that he could no longer be cautious, or he could walk wantonly among the ghosts and ghosts of the Black Mountain like the powerful ghost disciples he had seen before, plundering what he needed.

However, Xu Dao still suppressed his excitement, he did not choose to rush directly to the central area of Montenegro, but wandered around the outer area first, and marched inward.

Along.

Xu Dao encountered a lot of demons such as corpse rats, ghost clams, and bloodthirsty mosquitoes.

Among them, a huge number of them with deep qi were all bypassed by him temporarily.

The lone and weak ones were immediately swarmed by the grasshoppers, and in a moment they were eaten cleanly, turning into rations for all the mayflies.

In this black mountain, the Nanke mayfly in Xu Dao's hand showed its ferocity for the first time.

The corpse comes to gnaw the corpse, the demon comes to kill the demon, and the ghost comes to eat the ghost.

Walking out of the cave, Xu Dao drove the insect swarm through the forests and valleys, and there was almost no grass in the places he passed, and only some powerful demons and ghosts would be let go.

However, the more he advanced towards the place where the aura was strong, the more demons and ghosts Xu Dao encountered, and the stronger his strength became.

But at the same time, the flesh and blood of the demons and demons he obtained also became more and more refined, and the grasshoppers ate it, which could increase the size and strength of the grasshoppers.

Xu Dao saw the power of the grasshopper swarm, so he let the grasshopper group devour the spiritual materials, and began to consciously capture the demons and ghosts and feed them to the grasshoppers.

In about a day's work, he left the cave for nearly a hundred miles, and most of the 156,000 grasshoppers under his command had been lost, and only 50,000 or 60,000 remained.

But these fifty or sixty thousand are all left after the elimination of the weak, all of them are fierce and bloodthirsty, and there is demonic energy in their bodies, and they are already qi-refining level monsters.

Although they are very weak and can only prey on monsters like corpse rats, thousands of them can fight and kill the monsters in the early stage of qi refining when they work together, which is quite fierce.

So Xu Dao used them to try to hunt down more powerful demons.

The chosen target is a bear with an astonishing corpse.

I don't know what the specific type of Xiong Zhen is called, but its muscles, bones, and fur are as tough as steel, strong and strong, running like thunder, and can also spit out black gas, rotten flesh and bones, comparable to a Taoist in the middle stage of qi refining.

But under the bite of the grasshoppers in the sky, the bear has no way to do it.

The dense grasshoppers landed on its body, constantly burrowing into its seven orifices, and the thick corpse qi on its body did nothing.

Wait until thousands of mayflies have successfully burrowed into its body and gnawed at its flesh and blood together.

In less than a quarter of an hour, the Xiong Zhen in the middle stage of Qi refining was devoured alive by the swarm of mayflies.

During this period, the number of damage caused by the swarm was less than 3,000.

And after this battle, the other grasshoppers got the benefits again, and all of them grew fat and strong, and the corpses were full of energy.

Seeing this, Xu Dao knew even more about the power of this batch of Gu worms under his command.

As he guessed, with this mayfly in his hand, his strength could be comparable to that of a Daoist in the late stage of Qi refining, and he could easily kill the demons and Daoists in the middle stage of Qi refining.

For a moment, Xu Dao was still thinking in his heart:

"Nanke mayflies are so powerful, if I raise millions, tens of millions, or even hundreds of millions, I can also fight and kill the foundation building realm......"

But when he thought about it, he immediately came to his senses.

Although the Nanke mayfly reproduces quite quickly, not every grasshopper that breeds is very powerful.

Its growth consumes corresponding resources, if it only eats grass and trees, its strength is like that of ordinary ants, it can not fly more than ten zhang, and its strength is not more than a grain of rice.

And if you want to only have demon qi, you must feed the corpse qi and aura, and the flesh and blood of demon beasts.

With so much demon beast flesh and blood, if it were placed outside of Montenegro, Xu Dao would not be able to afford it.

That is, in the Black Mountain, there are many spiritual things and demons everywhere, so he can raise such a batch of fierce Gu worms by chance.

And the grasshopper can't grow its strength unscrupulously, each of them has an upper limit, and at most it can grow to the same level as the ant king.

Once they reach the realm of the Ant King, the other mayflies can no longer increase their strength by devouring flesh and blood.

Combing, Xu Dao looked at the Nanke mayflies in front of him, and suddenly found that their aura was already similar to that of the ant king, and they should be about to reach their limit.

Once the limit is reached, if Xu Dao wants to increase the power of his insect swarm, he must return to the cave and cultivate a new batch of grasshoppers.

After combing it out, Xu Daodun knew how to use the Nanke mayfly.

He looked at the dark but extremely strong aura of the Black Mountain Ghost in front of him, and his heart was pleasantly surprised.

"You have to take this opportunity to hurry up and cultivate Nanke grasshoppers, the more qi-refining level grasshoppers, the better, if you can have dozens or even millions when you go out of the mountain, then you will make a lot of money!"

For a while, Xu Dao's idea of contacting other Taoists was much weaker.

Compared to improving his own cultivation, it seems that cultivating Nanke Grasshopper has increased his strength a little more.

However, the former is the fundamental, and the latter is only external...... But correspondingly, the opportunity in front of us is also not to be missed, and the time will never come.

Harnessing the remaining Gu worms, Xu Dao hesitated as he continued to wander in the Black Mountain.

When he found several Daoist breaths, another group of Daoists appeared in his sight. The other party was dressed in a Taoist robe with white lines on a black background, and he looked like a Taoist disciple with white bones.

Looking at the White Bone Guan Daoist in front of him, Xu Dao suddenly thought about it, and he could control the Gu worm and fly over.

He decided to choose both!
