The primordial era began with the Upper Cave Man.

boom!

A boulder with a diameter of over fifty meters rolled down the mountain and crashed heavily into a crossroads, blocking a narrow valley road. At the same time, it startled a swarm of insects and birds, which fluttered and scurried about in all directions.

Only a ten-foot-tall, one-horned beast stood motionless, showing no sign of panic, lying on the ground and gnawing on the corpse of an eight-legged, headless behemoth.

Tweet!

At that moment, several sharp whistles rang out from both sides of the valley path.

Then several more urgent whistles echoed through the valley.

Waaah!

After a few whistles, a burly figure, half-naked and holding a stone spear, leaped down from the right side of the valley.

"Unicorn! Prepare to die!"

This burly man was none other than Luo Zu. He had gathered the people of the settlement and set up this trap, intending to fight this giant beast, which he had classified as a level six ferocious beast, one-on-one.

According to Luo Zu's classification of wild beasts and ferocious creatures in the mountains, there are six levels. Level one consists of small animals like chicks, ducks, and mice. Even young humans can kill these small animals when they are alone. There are many of these small animals in the mountains, but because they are numerous, very united, and have excellent escape abilities, they are the most difficult to catch.

Level 2 consisted of small herbivores and some small carnivorous predators in the mountains, which were the most common prey of the "Upper Caveman," such as unicorns and six-legged lynxes. Level 3 consisted of wild animals taller than humans, which were also important targets for the "Upper Caveman."

Level four refers to giant beasts over ten feet tall, such as the eight-horned water buffalo. Level five is the large water buffalo captured last time, which was two or three feet tall.

Level six is ​​a giant beast that is even taller, like a small hill.

Although such behemoths were less than ants to the immortals and gods of the primordial world, they were something that the insignificant human race could not afford to provoke. But that was in the past, not the "caveman" after Luo Zu joined the fold.

As for this kind of hierarchical division, although it is somewhat out of place in the prehistoric world, it is also a habit of Luo Zu, a transmigrator. When his horizons broaden and he has connections with the gods, he will ask them how they classify the various things into different levels.

This was Luo Zu's first real battle since emerging from seclusion, and he immediately chose the giant beast that was entrenched next to the "Mountain Cave" settlement.

Luo Zu named it a unicorn. It was over ten zhang tall and nearly thirty zhang long from head to tail, about the size of a train, or even a train would look thin compared to it.

It has hard armor. Even the strongest warrior in the settlement, Ironhead, could not pierce its skin with a spear made of stalactite. Ironhead has the innate ability to make his whole body hard, and his strength was increased three or four times by Professor Luo Zu's breathing technique, but he still failed in front of it.

Fortunately, he was well prepared and Luo Zu had a backup plan to rescue him. However, Tie Touwa also lost a hand, which was torn off by the unicorn.

Ironhead survived, but the others who attacked the unicorn suffered casualties. Two died on the spot, three were crippled, and the rest fled in panic. Some fell into deep ravines and died, while others crashed into rocks and fell into unconsciousness.

Of the eighteen men who ultimately attacked and hunted the unicorn, only twelve returned, and four of them were crippled.

The main reason was that they thought Ironhead would draw the fire, so the main preparations were focused on Ironhead. Their plan was to scare the unicorn into the trap they had dug. But they never expected that the unicorn would not be afraid of their scare at all, and instead charged at the team that made the loud noise.

Imagine a behemoth, comparable to a train, charging head-on at over 80 kilometers per hour.

So in the end, it was the "caveman" hunting team that was terrified by it.

This is why such a tragic event occurred.

The Upper Cavemen continued to keep an eye on it, but did not hunt it down again. However, they gradually uncovered its habits.

Now, it is up to Luo Zu, the de facto leader of the "Cavemen," to avenge this blood feud for his people.

Boom boom boom!

Luo Zu galloped down the mountain, his bare feet crushing the rocks on the road, leaving deep footprints that sounded like muffled thunder.

Ordinary wild beasts would have been terrified and fled in panic, but the unicorn's eyes were bloodshot and it was in a frenzy. Its nostrils, as big as a human brain, were spewing out columns of white mist. It dropped the food in its mouth, and then its ten thick legs stomped neatly on the ground. Swinging its yellowish, sharp unicorn horn, it charged towards Luo Zu.

Rumble!

Suddenly, the rocks seemed to be blown up by explosives, flying and splashing into the sky.

It's very close.

In just three seconds, the man and the beast were only three zhang apart.

Then, when they were only three feet apart, Luo Zu suddenly slid out.

The unicorn was charging forward at great speed, its body unable to make any further changes; its ten thick legs could only continue to gallop forward.

Luo Zu had already used this opportunity to burrow into its lower abdomen.

Its ten legs are all over ten feet long. Even when it plows the ground with its head down, Luo Zu can still slide out from below with its agile movements.

Then, as Luo Zu slid in, he used his spear to thrust it into the unicorn's belly, and a burst of bright red flames bloomed on the unicorn's abdomen, like a fire lotus blossoming in the summer.

boom!

The unicorn exploded the instant the fire lotus bloomed.

Splash!

It was as if a popcorn machine had exploded, with blood and flesh splashing into the sky without restraint, staining half of the verdant mountain red.

After a rain of blood, not only did the strong smell of blood spread, but there was also a faint smell of burning, sometimes masked by the smell of blood, and sometimes wafting into people's mouths and noses.

As for the instigator, Luo Zu, his body had been directly pressed into the soil by the molten flesh and blood from the unicorn explosion, as if he had been buried directly in this pool of blood and flesh.

The "cavemen" watching from the mountaintop stared in astonishment, mouths agape, completely bewildered and unsure how to react.

"Hahahaha!" At this moment, Luo Zu, who was lying in the rotten flesh of the unicorn, leaped up and stood three zhang high, then stood on a messy mountainside and laughed incessantly.

The "caveman" was awakened by Luo Zu's outburst. Bald Fire Boy was the first to jump out of his cover, brandishing his stone spear and shouting, "Boss is awesome! Boss is awesome!"

The other "caveman" immediately echoed: "Boss is awesome! Boss is awesome!"

"..."

This phrase was also taught to them by Luo Zu...

This guy doesn't even teach them anything good.

But Luo Zu thoroughly enjoyed the support; he raised his hands high and shouted:

"Long live humanity!"
