The primordial era began with the Upper Cave Man.

Chapter 144 Soul Searching, Mind Extraction, and Memory Capture: The Spiritual Brain Level Up

"The Sword of Annihilation, through the combined deduction of all the demon gods... will naturally restrain all witch races, including the Ancestral Witches," Huang Liulang said weakly yet insanely.

"However, to forge the Sword of Annihilation, one ingredient is missing. The demon gods couldn't deduce it, nor could the Heavenly Emperor and the Eastern Emperor calculate it, but I have found it."

"He's a human." Seeing him becoming increasingly arrogant, Luo Zu reached out and grabbed his frail soul form.

"Yes, it's you humans."

"But I can kill you at any time now, so what if you find out?" Luo Zu said calmly.

"As soon as I discovered it, I reported it to my grandfather. What do you think?" Huang Liulang's faint senses were fixed on Luo Zu, as if he was looking forward to Luo Zu's reaction.

Korozu remained expressionless, seemingly unmoved.

But Huang Liulang didn't care about any of that, and just kept saying to himself, "You humans all have to die. Even if you kill me, you'll have to come and join me. It won't be long, it won't be long. I'll be waiting for you."

"No rush." ​​Luo Zu still didn't kill him directly.

As for this news, Luo Zu had no way to verify it. Only when the demon race came knocking on his door one day would he be able to find out the result by asking them.

They still need to hurry up with their cultivation. These great figures will definitely need time to deduce. If they want to use the human race as a catalyst to refine the Witch Sword, they need to deduce even more carefully. After all, it involves great figures like the Ancestral Witches, who will definitely calculate carefully.

Of course, these thoughts were just wishful thinking on Luo Zu's part. At this moment, he could only think positively, and he was not sure what the outcome would be.

"Fine, I'll expend some effort today to extract your soul and examine your memories." After thinking it over, Luo Zu realized that daydreaming wasn't a solution, so he decided to take action directly. He was proficient in over 3,600 immortal techniques, some of which concerned the spirit and soul.

Seeing that Huang Liulang's soul was already empty and teetering on the brink of collapse, as if it were about to be scattered at any moment, he felt that he didn't need to waste any more time with him. Before, his soul was still intact, and even the Celestial Immortal level soul spirit Luo Zu had difficulty breaking through. Now, after being tormented by Luo Zu for more than half a year, his soul was already broken and could hardly stop his soul-searching immortal technique.

Therefore, Luo Zu doesn't need to be polite with him.

This giant weasel is no loss, but we can't let it kill the human race.

As Luo Zu unleashed his immortal technique, it was now a "Great Immortal Technique," a combination of Luo Zu's seven spiritual and soul-related immortal techniques.

After this magical technique was completed, Huang Liulang's manic laughter came to an abrupt halt.

His soul began to dissipate, and the spiritual fluctuations within him gradually subsided, but just as his spirit was about to perish...

令！

A shout escaped from Luo Zu's mouth, but it was silent, yet it seemed as if the word he uttered echoed endlessly throughout the immortal realm.

Then Huang Liulang's spiritual energy suddenly surged, and the crashing sound was the response of the spiritual energy storm in the immortal realm being broken open.

Then Huang Liulang's spirit completely collapsed, and the group disbanded.

Luo Zu, standing quietly in front of him, watched all of this unfold.

"This guy is lying to me." A slight smile appeared on Luo Zu's expressionless face.

The Extinction Sword is indeed a real thing, and he did discover that humans could use it to complete the Extinction Sword. However, he has not yet reported this to his demon god grandfather, because he is not sure and needs to experiment with it himself before reporting it.

However, he was not the only demon to discover this. He had an accomplice who had planned to go directly to the Chuxiong tribe to capture human slaves for experiments after the great battle. However, he was severely injured first and then tried to cross this land to return to the Chuxiong tribe, but he was trapped here.

Previously, he had planned to use his own Yellow Sand Pearl to create a clone identical to himself, but he never expected to be captured by Luo Zu and brought here, where he suffered endless torment.

As for his accomplice, who went with him, he too suffered a severe injury...

They're probably dead by now.

Of course, this is not foolproof. Without witnessing his death firsthand, without personally killing him until his soul was scattered, how could Luo Zu be certain that he was dead?

Therefore, Luo Zu decided to first write a letter to inquire about the lost one, then obtain a certificate from the Wu tribe, step onto the battlefield, and search for that fellow based on the mountain and landforms in the weasel's memory.

As for what to do with the "caveman"...

Tie Tou has also reached the Refining Spirit Return to Emptiness stage, and Huo Wa is following closely behind. Now, there are capable people in the tribe. Moreover, establishing diplomatic relations with the Re Wu tribe and becoming allies can also provide some protection. We can discuss with the Re Wu tribe about having them send people to patrol Luoxiang from time to time.

Moreover, before that, Luo Zu would first clear out the surrounding giant beasts and then sweep away those demon beast clans, so that the living environment of the "caveman" could be under control.

Besides, he won't be away for too long, maybe ten days to half a month, or at most half a year.

They might even leave early and return late.

However, before that, a message needs to be sent to the lost, which is simple; the Wu tribe's earth vein communication method can be used.

Before that, he still needed to refine the Exquisite White Aperture Purple Gold Pill.

I already have one, but the more of these things the better.

It's a pity he can't refine the top-grade Earthly Fiend Pill.

The main reason is still the lack of raw materials.

There isn't enough uranium metal in the veins of Luoxiang Mountain to refine the top-grade Earthly Fiend Pill. As for the next best thing, it's not good enough to refine such a high-grade Earthly Fiend Pill.

As for refining hydrogen bomb pills, Luo Zu did not use any methods and left it in the contingency plan for the time being.

However, the Reiki brain can now be upgraded.

The new template has already been constructed by Luo Zu, and now all Luo Zu needs to do is convert the current spiritual energy brain one by one.

"My daily schedule is packed, I've become my own death knell," Luo Zu sighed.

It was because the matter of the Demon-Slaying Sword came so suddenly that he had to bring forward the things he had done before.

"A good mind is essential for a battle of wits; you can't lack it, you absolutely can't lack it."

The structure of the new Reiki brain is not unusual; it still uses Reiki storms to transport various thoughts and ideas and store a great deal of knowledge and memory.

However, the spiritual energy storm will transform into tiny particles that closely follow the accelerated movement of the runes, so the speed of transmitting thoughts will be faster and the efficiency will be higher, while the storage capacity will remain unchanged.

This speed of thinking will be three times that of the original spiritual brain and 4.5 times that of the previous dharma brain.

If each Reiki Brain has improved so much, what kind of improvement will occur when all seventy-two Reiki Brains are combined?

However, this transformation will also take three days.

With his mind focused, Luo Zu received Wu's reply.

"This demon has been severely injured by me and has escaped into Xiyun Marsh. I have already mobilized the witch clan in Xiyun Marsh to pursue it."
