The ship fled, and the main gun was fired again.

"Boom!"

The purple pillar of light blasted out again, and in an instant, it arrived in front of the Devouring Demon Worm.

But the Devouring Demon Worm quickly coiled up and hid its head in its body.

"Boom!"

The Devouring Demon Worm was blasted away, and dense wounds and disgusting wounds appeared on the huge worm's body, and thick green blood continued to drip down, and it was almost converging into a small river under it.

It glanced viciously in the direction of the ship, then slammed its head into the ground, and soon disappeared completely underground.

"Xiao Jin, don't let it escape, keep bombarding!"

Cheng Bo hurriedly urged, if this guy is allowed to escape, it will cause great harm to this world.

"Master, the spaceship's energy is already insufficient, and it needs to replenish its energy, and it no longer has enough energy to fire another main cannon!"

Hearing this, Cheng Bo felt very sorry in his heart and asked, "Can the spirit stone be used to charge energy?"

"Yes, as long as the master puts the spirit stone into the energy furnace, the energy can be automatically extracted!"

So, under the guidance of Xiao Jin, Cheng Bo came to the energy room.

"Xiao Jin, how many spirit stones do you need to fully fill the energy of the spaceship?"

"Fifteen million eight hundred and thirty-six!" said Xiao Jin.

More than 100 million spirit stones were nothing to Cheng Bo, and he directly put the spirit stones needed by the spaceship into the energy furnace.

"Master, because the spirit stone is not the purest energy, it needs to be refined, the duration is thirty minutes, once the energy is replenished, you can fire twelve main cannons in succession!"

"Good!"

Cheng Bo nodded, and then probed his spiritual power into the ground.

Spiritual power extends in the soil, and it will be consumed to a certain extent, and it is very unrealistic to use spiritual power to search for the whereabouts of the Devouring Demon Worm underground.

Unless it appears on its own, it is almost impossible to find it.

Days flew by.

The detection light wave on the spaceship shrouded the entire Tiannan Domain, and as long as the Devouring Demon Worm dared to appear, Cheng Bo would immediately get the news.

But for a few days, the guy didn't show up, perhaps, he was recuperating from his injuries.

At the same time, his popularity has been growing wildly in the past few days, making his total popularity already reach more than 52 billion.

Promoted to level ten, it consumed three hundred billion reputations.

To be promoted to level 11, it is estimated that it will take 70 billion, or 80 billion.

In the blink of an eye, another ten days have passed.

Cheng Bo's popularity has grown to 68 billion.

But the Devouring Demon Worm still didn't show up.

Suddenly.

A voice sounded in Cheng Bo's mind, and he hurriedly clicked on the task icon and found that the new task had been refreshed.

"Task, kill the Devouring Demon Worm within one year, succeed, reward three tickets to the eleventh level mall, fail, all professions will drop a realm!"

"Why? I rely on the strength I have gained, why should I be downgraded?"

In this regard, Cheng Bo was very dissatisfied and questioned the system.

The system was very cold and didn't pay attention to him.

In the end, Cheng Bo had no choice but to take on this task, before, he felt that he was no longer too dependent on the system, but now it seems that it is not the case at all, even if he cultivates himself?

If the system wants to strip away his cultivation, he can't do anything about it at all.

Thinking that the system could lead him through various worlds, he suddenly felt that his previous idea was very naïve.

Since life can't resist, then accept it well, but Cheng Bo believes that one day, he can get rid of the control of the system, and now, he just needs to use the function of the system to keep getting stronger.

"Master, the Devouring Demon Worm has appeared!"

Xiao Jin's voice suddenly sounded, and then a map appeared, and the red dots on the map were the location of the Devouring Demon Worm, which was a small city on the edge of the Tiannan Domain.

"How much time does it take to rush over?" Cheng Bo asked in a deep voice.

"At least an hour!" said Kogando.

"Fly with all your might!"

Cheng Bo ordered.

An hour later, Cheng Bo finally arrived at the small city, but the whole small city had become an empty city, and the souls of all living beings were devoured by the devouring demon worm, and in the center of the city, there was a large hole leading to the ground, from which the devouring demon worm escaped.

Slight hesitation.

Cheng Bo put away the spaceship, and then jumped into the hole.

Going 10,000 meters deep into the ground, the entrance of the cave becomes horizontal.

Tens of thousands of meters ahead, an underground river appeared in Cheng Bo's sight.

"What a cunning fellow!"

Cheng Bo frowned and chased forward along the underground river.

But after chasing some distance, he immediately turned back and chased upstream.

Two hours later, he reached the source of the underground river and found another hole in the ground.

So, dodge into the hole and continue to track.

Devouring Demon Worms emit a foul smell all over their bodies, so the strange smell in the cave is very unpleasant, making people feel sick and vomit.

A day later.

Cheng Bo returned to the surface from the underground, because he devoured the demon worm and created a large number of underground passages underground, and deep underground, his spiritual power was also affected by the magnetic field in the center of the earth, so it was difficult to track down the devouring demon insect.

A few days later.

There is another city in the Tiannan Domain that has been devoured by the Devouring Demon Worm, and when Cheng Bo arrived, he was still one step too late, and the other party had already fled.

And the devouring of demon insects also spread rapidly.

The entire Tiannan Domain was panicked, and it was the Zhenjiao Immortals of Tianxiang Palace who released terrifying monsters such as devouring demon insects, so the people of Tianxiang Palace had become rats that everyone shouted and beaten.

As a result, the countless branches of Tianxiang Palace were breached, and the shops were looted.

In just a few days, the branch altar and all the shops in Tianxiang Palace were looted, and countless disciples died.

"Ma Ma Pi!"

Cheng Bo wanted to curse people, maybe it was because the Devouring Demon Worm had suffered a loss at his hands, and he had been fighting guerrilla warfare with him, and every time he devoured the lives of a city creature, he immediately escaped into the ground and hid.

He followed it several times, but found no trace of the other party.

"If it goes on like this, I'm afraid the entire Tiannan Region will be finished!"

Cheng Bo was very worried, and what worried him the most was that once the devouring demon worm swallowed the souls of the entire Tiannan region, how powerful would it be?

True Immortal is just a general term for immortals.

The immortals after the tribulation are called human immortals, and after the human immortals are the earth immortals, after the earth immortals are the heavenly immortals, and after the heavenly immortals are the golden immortals.

When the Devouring Demon Worm had just gotten out of trouble, it was at most in the early stage of human immortals.

Now after devouring the creatures of several cities, it is estimated that it has reached the middle stage of human immortals, or even the late stage, if it is allowed to swallow the souls of the entire Tiannan region, it may be able to promote to earth immortals.

At that point, it will be even more difficult for him to kill the Devouring Worm.

"We have to ask for help!"

Cheng Bo thought secretly, and then, he drove the spaceship straight to the Heavenly Peerless Domain, but first, he went to the Taizhen Immortal Mansion to pick up Han Li and Zhang Ying.

As for the reason, it is very simple, Han Li is the protagonist of this world, and he has great luck.

With him together, the success rate of killing the Devouring Demon Worm will increase a lot.

After Cheng Bo explained the dangers of devouring demon insects to Han Li and Zhang Ying in detail, their expressions became extremely solemn, and their eyes were also full of worry about the Tiannan Region, after all, they were all monks of the Tiannan Region.

"Big brother, what do you want to do?"

Han Li asked.

"I decided to go to the Zhentang Immortal first, ask him to contact a few more immortals, and then go to the Tiannan Region to hunt down that Devouring Demon Insect!" Cheng Bo said, with his strength alone, it was very difficult to kill the Devouring Demon Insect.

Onihudo.

Seeing the three Cheng Bo who suddenly appeared, the hall master Duan Baiyu was not much surprised.

After all, it is not uncommon for a cultivator to retreat for three or five years, not to mention, Uncle Shi is still more optimistic about Cheng Bo, and Duan Baiyu does not take this matter seriously.

"Brother, I'm going to the main hall to meet the immortals of the town hall, I have a big matter to discuss, I hope you can help introduce it!" Cheng Bo directly explained his intention.

A look of embarrassment appeared on Duan Baiyu's face: "Brother, Uncle Shi's temper is not very good, if there is nothing important, you should not disturb him, otherwise, once Uncle Shi is angry, you will suffer!"

Cheng Bo said with a solemn expression: "Brother, this matter is too important, it is related to the survival of the entire Heavenly Peerless Domain, so I have to meet the Zhentang Immortals!"

Duan Baiyu was stunned for a moment, glanced at Cheng Bo deeply, and then nodded: "Okay, I'll take you there!"

A day later.

Cheng Bo and his entourage arrived at the Agni Fire Hall.
