It was naturally impossible to imitate the past Lan Si and keep a greater god's high-level Godhead in a person's body for a long time. No one could endure that.
But even such a short fusion period was still enough to boost the fusion target to an unimaginable level.
After Gu Nan checked Vivian's condition, he immediately let her go to try her hand at godslaying. In reality, as the first person to successfully fuse with the Nightmare Godhead, her fusion was very incomplete, and her strength barely reached Tier 6.
It wouldn't be easy for her to kill the similarly Tier 6 Goddess of Radiance.
But this was no longer important, because Vivian's greatest value was to disrupt the Godhead's stable structure. After that, the fusion success rate of all subsequent subjects would be greatly improved, and Gu Nan would be able to produce enough blasphemers.
Speaking of which, the current situation was much better than in the game. In the past, there was no greater god's Godhead as material for him to cultivate blasphemers with.
Things wouldn't have gone as smoothly if he only used a Tier 10 Godhead as the blueprint.
...
In the days that followed, Gu Nan remained inside his own Divine Kingdom, waiting for the Blasphemer Project to yield results, and at the same time, he was also advancing another project.
This project was to compare information from the Scholar Temple against his own memories and analyze which historical events may have been caused by the intervention of the Myriad Heavens.
Since he visited the Gap World and read the game data saved from back then, Gu Nan naturally wouldn't overlook anything thanks to his vastly improved memorization ability.
Gu Nan didn't rely on anyone else to perform the analysis and comparison work, personally completing every step of the project.
Daoist Yellow Springs said he saw Jiu Po, but Gu Nan knew all too well that the other party's avatar—the God of Twilight—never appeared in the game. Instead, the NPC related to Zero appeared as normal.
In other words, Gu Nan first noticed the other party precisely because the actual history here did not match the one from his memories.
If people who came from the Gap World could all see a part of history, then how could these discrepancies be explained?
After having the two sides' information for comparison, Gu Nan's work proceeded smoothly. It was only by observing the entire history of the World of Gods that Gu Nan made new discoveries.
There were actually quite a few extra gods like the God of Twilight, but most of them didn't have clear titles unique to gods, and even their appearances in the World of Gods were short-lived.
This group mainly appeared during the Third Divine War and remained so until now. They were clearly Star Rulers from the Myriad Heavens.
However, like the former God of Twilight, due to their low levels, their influence on the general trend of history was insignificant, and the changes to history were merely limited to the local regions.
Especially after the Fourth Divine War, the entire World of Gods was reshuffled, and Star Rulers withdrew en-masse, making the current World of Gods similar to the one from Gu Nan's memories.
"Not a single person from the Myriad Heavens appeared in the game…" After Gu Nan came to this conclusion, he couldn't help slowly standing up.
This conspicuous regularity that completely separated and isolated the two worlds from each other couldn't possibly be mere coincidence.
'The Gap World probably holds other secrets. It's impossible for Daoist Yellow Springs to stay in the gap between two worlds for thousands of years just for some tranquility.' Gu Nan had a suspicion in his mind.
Gu Nan had contact with Jiu Po and knew that back when Daoist Yellow Springs left, he claimed to be looking for his "hometown".
But no matter what, ultimately, Gu Nan still needed to increase his strength.
If Gu Nan was already at Tier 15 right now or even post-Third Round, then he could simply take over the two major worlds, gathering both worlds' power to investigate the gap between the worlds and explore the secrets inside.
Just when Gu Nan was thinking about his next steps, Yan Xiaoxiao suddenly projected a human form and came up to him.
"Teacher, something happened." Yan Xiaoxiao's face was unusually grave. "An Tiansheng died, and Lan Si and Xie Yun were also heavily injured."
Gu Nan slowly turned his head, his face expressionless. "Who did it?"
"Cloud Dream Heaven… But the root of this matter still lies in the incident with Imperial Glory Heaven," Yan Xiaoxiao explained as concisely as possible.
The matter wasn't complicated.
Although Gu Nan cut his Divine Kingdom off from the outside world, people inside the Divine Kingdom would still go out to carry out trade and daily tasks.
And some people from the player army, like An Tiansheng and Xie Yun, also spent most of their time outside the Divine Kingdom.
This incident involved a relatively important trade where a batch of top-tier resources needed to be transported, so Red Tail invited Lan Si, An Tiansheng, and Xie Yun to jointly keep watch.
But even with such a lineup, they still received a powerful blow. The attacker was none other than Cloud Dream Heaven.
"Cloud Dream Heaven is connected to Imperial Glory Heaven?" Gu Nan raised an eyebrow.
"The previous Star Ruler of Imperial Glory Heaven used to be good friends with Dream Immortal. It was also during the battle that caused Dream Immortal to fall into a deep slumber that he suffered irreparable injuries."
Yan Xiaoxiao had obviously investigated thoroughly and sorted out the whole incident.
Finally, she added, "In addition, we found out that the Heaven-God Alliance might have been involved behind the scenes here as well…"
But Gu Nan stood up and interrupted her, "That's no longer important."
...
Cloud Dream Heaven.
Standing in front of Dream Immortal was Huo Kui. After hearing about the conflict between the two sides, he rushed to Cloud Dream Heaven as soon as possible.
"This matter is not simple." Huo Kui said, "Taisheng is not someone who likes to rely on others. She didn't ask you for help before, so why would she suddenly do it now?"
Dream Immortal smiled faintly. "I know. But I watched Taisheng grow up. Now that things have come to this, I have no reason to stay out of it."
Huo Kui was still trying to dissuade her, "Gu Nan's massacre of Imperial Glory Heaven happened before he ascended to Unified Dao. Now…"
"No one said this is revenge." Dream Immortal sneered, "It's just a normal conflict. If Gu Nan is dissatisfied, then he can talk to me."
Huo Kui couldn't help giving a deep sigh. He knew his old friend was determined to oppose Gu Nan.
But she had clearly witnessed Gu Nan's power. Back then, she didn't even take revenge for her son's death, yet she was now taking action just for an outsider?
Huo Kui glanced at Dream Immortal's calm face again, then finally nodded slightly.
Seeing that he finally understood her intentions, Dream Immortal couldn't help smiling. But just when she was about to speak, her expression suddenly changed.
"Gu Nan went to Imperial Glory Heaven!" A cold glint flashed through Dream Immortal's eyes. "Is he planning to attack Taisheng, just like this?"
It would be too shameless for a mighty Unified Dao bigshot to attack directly without any evidence.
"You'd better head to Imperial Glory Heaven immediately." Huo Kui, who had witnessed Gu Nan's rise and knew his style, couldn't help saying, "He's indeed capable of such a thing."
On the other side, in the Imperial Glory Heaven that was just rebuilt not long ago.
An enormous shadow greatsword tens of thousands of meters long fell like a meteorite and smashed into Immortal Empress Taisheng's just-rebuilt palace.
"Gu Nan!"
