"Damn, Xiao Kai, you are a bully on this cliff"

"Anchor: Silly, you have a gun"

"Poor primitives"

"Neanderthal Leader: Lao Tzu's TM is finished?"

"Lao Tzu bets five cents, what that Neanderthal wanted to say before he died must be that his mother sells batches"

"Anchor, your festival is shattered"

"Neanderthals: I've never seen anyone so brazen!"

The Neanderthal leader fell in a pool of blood, was shot by Li Kai in the bull's-eye, and was killed on the spot, but those online viewers with strong hearts complained one after another, saying that they felt sorry for the Neanderthal leader who was killed by one shot, that guy is so strong and strong, with a fierce face, at first glance he is a standard villain, and he is fully qualified to compete with the anchor, at least tens of thousands of words must be played (water) to end, but I didn't expect Li Kai to raise his hand and solve it with one shot, which is really exciting...

"Time is of the essence, so we have to do it quickly. Li Kai laughed dryly and explained to the audience. He won't tell everyone that he didn't dare to fight the Neanderthal leader alone because he didn't know the bottom of his heart.

Obviously there is a gun, why bother with it, am I a civilized person, okay, this is Li Kai's inner monologue.

"Wow!"

And after seeing Li Kai easily kill his leader, the remaining Neanderthals suddenly collapsed, and the black sword tiger immediately raised its tiger claws and directly slapped the two Neanderthals to death, and the remaining Neanderthals fled into the dense forest without looking back.

"Hmph. ”

Li Kai snorted coldly, the leader of the Neanderthals was dead, so he didn't chase these little shrimps anymore, stepped forward, and stepped on the bone spear that was regarded as a holy weapon by the Neanderthals.

[System Prompt]: You have completed the hidden mission, and the task reward is now issued.

The next moment he stepped on the broken bone spear, a system prompt appeared, which made Li Kai feel happy, and this time the task was finally completed.

A familiar white light appeared out of thin air, condensed and fell on his hand, it was a test tube syringe similar to the pet culture liquid he had obtained before, the only difference was that this tube of liquid was red, like agate, crystal clear, revealing a sense of showiness.

[Name]: Gene Complement Agent (Veterinary Use)

[Type]: Special (consumable)

[Function]: After use, the genetic defects of the organism can be completed, and the specific degree is subject to the qualification of the organism itself

[Scope of use]: Carbon-based organisms (except humans)

"Big Black, it's yours. Li Kai's expression on his face was already immune to the last sentence of the introduction, and he shook the test tube at the black sword tiger.

Obviously, except for the Black Sword Tiger, Li Kai really didn't know who to use it for.

Oh, by the way, there is also Xiao Hei, but this little guy is still 65 million years ago, even if he wants to take it, he can't do anything, not to mention, Li Kai has already given it the pet culture liquid.

[System Prompt]: The [Pet Slot] function has been turned on, and the host can check it on the "Main Page".

[System Prompt]: You have obtained the Genetic Supplement Potion (Veterine)*1, enable the [Pet Slot] function, and exchange for Gold*100

Before Li Kai could take a closer look, two more system prompts appeared in front of him, but this was not over yet, and before he could go to see if this pet pen was the same as he imagined, a ball of golden light appeared.

[System Prompt]: The conditions for completing the special reward have been met, and the special reward will be issued.

An obsidian-like broken crystal floated in front of Li Kai's eyes, and he couldn't help but spread out his palm, because the palm of his right hand was inlaid with an identical crystal.

After the new crystal appeared, the crystal that was originally hidden by Li Kai revealed itself in his palm, and the two crystals emitted a hazy shimmer, as if echoing each other.

[System Prompt]: Does the host choose to receive the new Prehistoric Heart (Fragment)?(Yes/No)

Since one has been bound, what else can Li Kai say, the natural choice is.

Sou~!

The fragment turned into a streamer of light, drilled into his palm, and fused with the previous fragment of the prehistoric heart, which was extremely weird, but fortunately, Li Kai had already experienced it once, so it was not strange, and he moved his fingers a little, and he was still flexible, and Li Kai hid it again.

However, with the new crystals fused, the information of the Prehistoric Heart Fragment has changed somewhat.

Name: Prehistoric Heart (Fragment)

[Attribution]: Li Kai

[Type]: Mysterious

[Energy value]: 0/100 (uncharged)

[Function]: Open the space-time gate (inactive), unknown

[Attributes]: Cretaceous world affinity +20, Quaternary world affinity +20

"Although the energy value has increased, and there is also an additional Quaternary world affinity, what is the use of this?" Li Kai was very puzzled, although this prehistoric heart fragment looked very mysterious, but it was not of any use at all, how to make it play a real role, Li Kai did not know.

As for why it is the affinity of the Quaternary, it is not difficult to understand, because the 10,000 years before the history of Li Kai belongs to the Pleistocene period of the Quaternary of the Cenozoic Era.

But the system did not answer this question, and Li Kai couldn't think of it even if he broke his head, so he simply stopped thinking about it.

His eyes looked at the main interface in front of him, and in addition to the host information, taskbar, and exchange shop on the main interface, there was indeed an additional function of a pet bar.

After clicking on it, Li Kai saw a pet bar interface similar to an online game, which displayed the words pet name, attributes, qualifications, etc., but it was blank and there were no pets.

[System Prompt]: The pet bar function has been opened, and it can currently accommodate 0/3 pets, Note: Only the creature (except humans) and the host have a friendship value of 100/100 to be included in the pet bar.

"Great!"

Li Kai laughed out loud at that time, this was simply the reward he wanted the most at the moment, he could keep the Black Sword Tiger by his side, and he didn't have to worry about it surviving alone in the Ice Age.

"Ah~"

However, just when Li Kai fell into Meizizi's fantasy, a faint human shout in the distance made him suddenly jump up and slap himself on the head.

He had been chasing down the Neanderthal leader before, and he rode the Black Sword Tiger and chased it out, but the group of saber-toothed tigers and cave lions were still there, and without the Black Sword Tigers, God knows if they would slaughter primitives like they killed Neanderthals.

"Dahei, quick, let's go back quickly!"

Li Kai didn't dare to think about it anymore, and rode back quickly on the Black Sword Tiger, and the previous joy was instantly dispersed.

"Roar~"

As if sensing Li Kai's anxious mood, the Black Sword Tiger roared and ran wildly in the dense forest.

......

At this time, the Neanderthal tribe was filled with fire, and the tents were lit up with flames, lighting up half of the sky.

But fortunately, the fire did not spread to the surrounding area and did not cause a forest fire, otherwise most of the creatures in the dense forest, including primitive people, would have been buried in the fire.

"Roar~!"

After the Neanderthals died and fled, the saber-toothed tigers and cave lions who lost their targets really set their sights on the primitive people of the Tushi tribe, they did not have the high spirituality of the black sword tiger, the black sword tiger was gone, the wildness prevailed, and they launched an attack on the primitive people of the Tushi tribe.

Fortunately, Batu was the first to wake up and wake up the kneeling tribesmen, so that everyone could resist, otherwise even if they were bitten to death by fierce beasts, this group of primitive people might also be regarded as a sacrifice to the totem.

Now they retreated into the circle of fire, relying on torches and spears to barely force back the approaching saber-toothed tigers and cave lions, hoping to wait for Li Kai's return.
