In the third month after Lu Qing began his retreat, Lu Mingchao set out from Jade Smoky Mountain with several family monks, aiming at one of the three threats that Lu Qing had left behind that must be eliminated.

It was an iron red worm swarm, the insect mother was a kind of demon beast that could reach the second order, and its own combat strength was not strong, but the most difficult thing was that there were usually thousands of iron red worms around a worm mother.

Ordinary iron red insects are not much of a threat, and the demonic power contained in their bodies is pitiful, only two palm-sized insects, which may not even be able to defeat a wild cat.

But if the number becomes thousands, it will be troublesome.

Moreover, after all, it is a demon beast species, when the number gathers to a certain extent, and there is the command of the insect mother, the demon power in the body of all the iron red insects will resonate, and the threat will be much greater.

However, before Lu Mingchao set off, he had received sufficient intelligence information and pointed out the location of the nest of this insect swarm. At the same time, according to the magic weapons and means she possessed, she also thought of a relatively easy way to deal with this swarm.

The four family cultivators she brought out were all people who practiced qi at the seventh level or above. None of these four people practiced fire and wood attribute exercises. These two attributes, which are used to deal with fire-attribute demon beasts such as iron red worms, will be restrained and will not have a good effect.

Before approaching the wormhole area, Lu Mingchao asked all the monks to start paying attention to the surrounding environment, and once they found the iron red worm, they must be dealt with and eliminated immediately.

This kind of insect swarm does not have the ability to remotely sense the death of a group member. As long as the bugs don't find out about them and spread the news, they can sneak in without the mother bugs noticing.

After getting closer to a certain level, the insects begin to become more and more dense, and the difficulty of cleaning up in advance becomes higher.

Lu Mingchao didn't force it to do so, after she estimated the distance, she turned on a spell she had mastered—the Cloud Mist Technique.

Under the cover of the large thick fog that was summoned, the monks advanced faster, and under the clouds, the iron red worms that also detected the enemy through vision were greatly reduced, and the detection range was greatly reduced, so they didn't have to worry too much about being discovered by the insects in advance. On the contrary, it is the perception effect within the cloud and mist provided by the cloud technique, and it can also find some insects one step ahead.

With the lowest level of wisdom of these insects, they can't understand that the dense fog that suddenly appears is composed of magic.

In this place, foggy weather is not impossible.

After clearing the path of the bugs that were bound to be disposed of, they rushed to the entrance of the wormhole.

This entrance, which appears to be about two meters in diameter, is immeasurably deep. It is difficult for ordinary people to enter it, and the insect ** part has also undergone the unique reinforcement ability of the iron red worm, so it is not easy to collapse and bury the insect colony alive in the ground.

But Lu Mingchao had another way.

She took out her 'Cloud Gathering Gu Cup', summoned a water mist, and transformed it into a highly corrosive poisonous mist through a magic weapon, urging it to pour into the wormhole.

At first, there was no reaction, but she didn't find it strange.

The insect swarm has built a nest underground, I am afraid it will be very large and complicated, and it will take some time for the poisonous fog to spread, so there is no need to rush too much.

Lu Mingchao had already been prepared, knowing that this would be a protracted battle, so he didn't push the poisonous mist too hard, but just maintained a relatively gentle output efficiency. She also held a spirit stone in her hand, and while exporting the poisonous mist, she also absorbed and refined the spiritual energy from the spirit stone to replenish it.

Then, insects came out of the mouth of the cave, most of them staggering, and all of them were wiped out by the monks who were guarding outside the cave. Similarly, some homing insects were also poisoned.

Three hours later, they could faintly feel something change underground.

"Get ready! the most difficult level is coming!" Lu Mingchao reminded, and at the same time, she herself suddenly strengthened her spiritual power output, and the poisonous mist that poured out of the Gathering Cloud Transformation Gu Cup became more and darker.

The other four monks were all vigilant.

Sure enough, after a while, a large number of insect swarms suddenly poured out of the wormhole!

The insects that rushed to the outermost were all swaying, and many of them fell to the ground when they rushed.

But these bugs still have instincts, and their formation of rushing outward is kept very tight, and a large number of bugs on the periphery have withstood the erosion of the poisonous mist by dying, but they have ensured the state of the bugs inside.

The dense swarm of insects looks a little terrifying, they open their teeth and claws, and the mouthparts that look a little hideous, if they bite someone, they will also bite off a piece of meat, and they will also inject fire poison.

The four Qi cultivators had a drill before they set off, and they were a little nervous at this time, but they weren't too scared.

The two water monks joined forces to drum up the water spiritual power and briefly summoned a large water source.

Qi cultivators' abilities are limited, and the water they summon can only be like a stream, but it is barely enough. This water poured into the cave, hindering the pace of the swarm to continue to advance, and some peripheral insects were even directly washed away and washed away.

Lu Mingling, who was also in the team, hurriedly took this opportunity to hold a black iron magic sword in his hand, and with words in his mouth, he summoned thunder and lightning.

Like Lu Chaoxi, he cultivated the Mingyang Thunder Classic, and he was one of the most outstanding disciples in the Ming character generation of the family. Although he has not yet reached the foundation building, he can't cultivate such a big move as the 'Xuanyin Yang Thunder Mantra', but with the strength of the seventh layer of qi refining, it is not a big problem to recruit some currents.

The electric current flew with the tip of the sword into the water, spreading and destroying a large number of insects.

And the one with the highest killing efficiency must be Lu Mingchao himself.

She no longer kept her hand, and after she launched the poisonous mist strongly, the power of the poisonous mist was much higher. And when the water flow is injected, her poisonous mist is combined with the water flow, rapidly spreading and strengthening.

This wave of insect swarms was disintegrated before they could break out of the wormhole.

A large number of insect corpses even blocked the entrance to the nest.

The earth-walking monk who didn't make a move just now urged his spiritual power to clear the entrance of the cave, and then Lu Mingchao began to pour poison into it again.

This process later lasted two whole days.

During this time, the resistance of the swarm came several times, but it was far from being as strong as the first time, and it was getting weaker and weaker.

In fact, by the eighth hour, there were no more bugs running out. After eight hours of continuous poisoning in the worm's nest, I am afraid that it has already been filled with extremely corrosive poisonous mist.

But the mother worm never appeared.

A few people were not careless, they sat down at the entrance of the wormhole, each took out a spirit stone, absorbed spiritual power from it, and while recovering from the state, they were also guarding the nest. Lu Mingchao also continued to pour poison into the wormhole from time to time to maintain the concentration of toxins inside.
