The primordial era began with the Upper Cave Man.

The newly cultivated cocoons of the insect mother have little activity, but according to Luo Zu's experiments, their allure to insects is still deadly. The insects will go crazy for them, just like snakes in estrus, constantly seeking out mates and frantically seeking to mate.

The allure emanating from the mother insect's cocoon is far more sophisticated. It's as if the mere smell of the mother insect's cocoon triggers a feeling of hunger that has lasted for centuries, and the mother insect's cocoon is the only food that can help them escape this hunger.

As for how to control the swarm of insects using it, just like that gorilla did, Luo Zu has not yet found a way.

However, the insect mother cocoon is only effective against ordinary insects, but not against insect demons. Perhaps there are more advanced insect mother cocoons that can be used to manipulate insect demons.

The main purpose of the cocoon that Luo Zu cultivated was for the hometown of the "Upper Caveman"—the valley!

The ancestor of Luo has now given this valley a name: Great Dragon Valley.

Although the Great Dragon Valley is no longer suitable for human life, it is not good for the ancestral land to be occupied like this. Moreover, the giant worm is also a considerable threat to the "Upper Caveman". If it is left unchecked, it may expand its territory in the future and even launch a sneak attack on the "Upper Caveman", which would be a disaster.

How can I allow someone else to snore beside my bed?

No doubt about it, let's do it!

According to Luo Zu's observation, the burrowing worm was indeed an insect, and not very intelligent. It was a ferocious beast with special powers, whose mind was full of eating and digging.

It loves to eat carrion and, by some instinct, it can command ghosts to help it capture and lure food.

In addition, it also spews out the terrestrial acid stored in its body from underground.

As for its exact size, Luo Zu has not yet determined it.

Although his Yang God's illusory form can burrow into the earth, hundreds of feet deep, that land is completely polluted by the earth evil stirred up by worms from beneath the ground. If Luo Zu were to invade it, it would likely cause unpredictable and terrible consequences.

As for the consequences, the worst-case scenario is that Luo Zu's Yang spirit will be corrupted, and the best-case scenario... is that there will be no consequences.

In addition, according to Luo Zu's observations over the past year, the area affected by the Earthly Fiend pollution is still expanding. Previously, it only affected the river valley, but now it has spread to the outer areas and even to the surrounding mountains.

It's about ten kilometers away, and only about twenty kilometers away from the settlement of the "Upper Cavemans," so this can't go on.

"Year 36 of the Primordial Era! July 8th!"

The so-called Primordial Era was established by Luo Zu himself, starting from the time of his birth. The calculation of the sun and moon was also roughly done by Luo Zu himself. As for achieving the same level of precision as in his previous life, Luo Zu would probably have to put in much more effort to calculate. However, Luo Zu doesn't have that much time now, so he didn't come up with the Twelve Earthly Branches, Heavenly Stems and Earthly Branches. He only created a rough set of eras and dates.

When Luo Zu has more time in the future, he will conduct a more serious study of these units of time and make more detailed distinctions.

"A record of today's expedition to Great Dragon Valley!"

Luo Zu is writing in his diary. Normal people don't write diaries, but Luo Zu is writing the records of a "caveman".

Written in the shamanic script, recorded on newly invented straw paper, and stored in a cool, dry cave, where the mountain breeze blows through every day to prevent it from getting moldy and rotting, and from being eaten by termites and woodworms.

While the use of straw paper was groundbreaking, it was rather outdated for such a mythical and ancient era.

According to Tang, the legacy of the lich has already been uploaded to the "cloud".

The demon race records its history and culture on the stars in the sky, just like the great law of worshipping the sun and moon for all living beings, which can be borrowed by all demons.

The Wu tribe, on the other hand, records their Wu culture in their bloodline, and as long as they reach a certain age, they can pass on these ancient memories one by one.

Due to their organizational structure and sphere of influence, those Xuanmen cultivators can only pass on their knowledge through "jade slips" or through certain texts.

In short, everyone's methods are diverse, but only the human race's civilization carriers have been updated to straw paper.

Therefore, the development of the human race still has a long way to go.

Let's get back to the point.

After recording his actions, Luo Zuzu began to act.

He stepped out of the cave and looked at the action team in front of him.

This is a special operation. Luo Zu has gathered the elite among the "Cavemen" and explained his purpose and the dangers of the Great Dragon Worm to them, so that they would support him. Only then did he begin to plan the next steps, and now it is time to put it into action.

"Gentlemen, for the future of humanity!"

"For humanity!!"

A group of people were drinking together.

The operation began immediately.

Iron-headed boy, Fire boy, Second boy, Stream, Mountain, Pig, Rock, Ridge, Ah-ne.

Including Luo Zu, there are ten people in total.

Each of them had refined their essence into qi and, under the tutelage of Luo Zu, mastered some spells, reaching level five. Although they could not directly harm the Great Dragon Worm, they could still assist Luo Zu in the subsequent battle.

The tasks for the ten people had been arranged long ago.

Iron-Headed Boy was proficient in earth and metal elemental magic. Later, he mastered more earth elemental spells, which allowed him to create a muddy area about thirty meters square, or to make the land hard. He, Yue, Yan, and Ling would then control the soil together to control the giant dragon worm.

Of course, if the size of the giant dragon worm exceeds their expectations, that is, its length of three kilometers, then the four of them will no longer carry out this order.

Huowa is proficient in fire magic. Under Luo Zu's urging, he has now refined his essence into qi and has gained extraordinary control over fire magic. Xi and Zhi follow him to control fire magic. Xi is good at wind magic and Zhi is good at wood magic. The two of them help Huowa drive the dragon worm in the right direction in the next mission.

With the supernatural power of seeing a thousand miles, Erwa also learned mental control techniques after refining his essence into qi. Because of his strong talent in mental matters, Luo Zu believed that his speed of refining qi into spirit might be much faster than that of other "caveman" people.

At that time, Erwa's main task, in addition to monitoring and observing the dragon worm, will also be to help Luozu cast illusions on it in order to control it.

However, if he finds that the dragon worm is uncontrollable, he will only need to monitor and observe it.

As for Luo Zu, his task was to use the No. 1 Cocoon of the Insect Mother to lure the Great Dragon Worm into a trap.

As for where the trap is?

It was the vast lake that Kuafu created by his footsteps.

According to Luo Zu's observation, for some unknown reason, this giant dragon worm was not afraid of the rainwater flowing from the other side of the lake.

Luo Zu suspected that the reason for this was likely due to the flesh and blood of the four-legged creatures that fought here that day, which had seeped into the valley.

It was this discovery that led Luo Zu to choose that lake. Another reason was that he also observed that the large fish in the lake had been hunting near the shore recently, and had appeared on the shore closest to this place.
