The eldest son's brain death had been confirmed as irreversible, which was both good news and bad news. The good news was that there was no need to worry about the eldest son suddenly recovering and then swinging around to give the surviving Pathfinder civilization a hard time. The bad news was that Hao Ren couldn't use "treatment" to restore the sanity of this planet's eldest son—this was one of his original plans, to find the eldest son's diseased brain core and then try to cure it. What if this eldest son wasn't completely insane? After all, it was difficult to completely kill a mythical creature that had completely merged with the planet. It was almost equivalent to destroying the planet as well.

However, Hao Ren had to abandon his treatment plan now—the patient's brain was gone...

The Tortoise Rock Platform returned to the surface, and the drone swarm had already built a temporary front-line base on the planet's surface: a silver-white alloy ground covered the land that had once been destroyed by artillery fire, covering up those ugly and terrifying cracks and craters. High command towers and various factories and laboratory facilities rose from this silver-white land. Although they were just modular temporary facilities, they gave this desolate place a bit of a "civilized" atmosphere.

This front-line base was located next to the Great Rift, on the battlefield of the Fortress's Last Stand, adorning the vast scorched earth plain like a silver bright spot. It didn't take the drone swarm too long to build such an outpost—they directly transferred the prefabricated modules from the space factory to the planet's surface via hyperspace teleportation, and simply connected them after placing them in the designated location. The prefabricated modules could complete the unfolding, deformation, welding, and "growth" of internal facilities within a few hours. When the Tortoise Rock Platform went to the Earth's core, there was only a chaotic collection of construction machinery here, but when it returned, it was a small but complete base.

The spaceship docked at the base's small airport, and Nolan finally enjoyed a long-awaited port overhaul: this was the first maintenance since she came to this godforsaken X-cluster and was almost cut in two. The ship girl cheerfully set off fireworks on the bridge for half an hour, but Hao Ren was having a headache in the temporary base's command center, staring at the holographic projection.

The holographic projection showed a detailed map of the planet's structure. Through several exploded views, viewers could clearly understand the planet's internal status quo. It could be seen that the interior of this planet, which coexisted with the eldest son, had been completely transformed. The eldest son's biological tissue could be found in the rock layer, the magma layer, and even the Earth's core. This ancient mythical creature had almost "eaten away" the planet. His tentacles had replaced more than sixty percent of the planet's internal support structure, and those huge cavities and faults were almost entirely maintained by those tentacles.

If the goddess hadn't considered the survival of mortal races when designing the eldest son as a "biological guardian," giving the eldest son a tendency to move towards the Earth's core and avoid damaging the planet's surface structure and resource reserves, this planet would probably present an abnormally terrifying image.

"Let's not talk about whether we have enough firepower, even if we do, we can't kill him," Izhaks said in a muffled voice. "The eldest son has completely merged with the planet, and what's even worse is that the eldest son once 'opened up' the planet three thousand years ago, which led to a third of the planet's structure still being cracked. There are faults everywhere, and all of them are relying on those tentacles to maintain the planet's structural stability. Once the eldest son completely dies, this planet will fall apart within a hundred years—the Pathfinders probably don't want to see this scene."

"Actually, the Pathfinders can immigrate, right?" Nangong Sanba tried to say. "Although they haven't found a suitable place to immigrate, we can help them find one—our detectors are more advanced than theirs. And the Pathfinders are all robots, as long as the mineral reserves are rich and the temperature isn't too different, their environmental adaptability is much stronger than carbon-based creatures. There should be many places where they can immigrate."

Hao Ren glanced at him: "I'll blow up your house and then tell you, 'You can just move, I'll introduce you to a new house if you can't find one'—what would you think?"

Nangong Sanba thought for a moment: "I live in your house now..."

Hao Ren: "...Damn it, I forgot about that."

Vivian sighed as she looked at the two unreliable guys: "Hey, you two are unreliable. Actually, what Nangong Sanba said is also a way. If you really face life and death, moving is better than dying, but then again, this kind of immigration can only be a choice when there's really no other way. As long as there are other options, you can't just blow up this planet. The Pathfinders have deep feelings for their mother planet—especially now that humans have left, they can't possibly watch their mother planet be destroyed, because this planet is the last memory their creators left them."

"How about slapping him in the face with a lullaby?" Lily said, gently swaying her tail. "We can't wake him up and we can't kill him, so let him sleep hard."

"Let's not talk about how much engineering it would take to evenly bury the lullaby device in every corner inside this planet. Even if we can solve the technical problems, this plan won't work," Hao Ren waved his hand. "The lullaby device has limitations. It can only suppress part of the eldest son's nerve activity, but it can't completely control him. After the lullaby is activated, the eldest son's tentacles may still have short-term twitches or other 'conditioned reflexes'. And long-term exposure to the lullaby will also cause the eldest son's body to atrophy and the strength of his physiological structure to decrease, which will still cause the planet to be at risk of falling apart."

Lily shook her head a little irritably: "This won't work and that won't work, then why don't we just build a brain for the eldest son with a nerve controller and a giant computer like we did on Purgatory Star, Landlord, do you remember? The natives there even built a city around the eldest son's artificial brain and go there to pilgrimage every day..."

Hao Ren stroked his chin: "Your suggestion is not bad, but building an 'artificial brain core' is not a matter of a day or two. This project is too big, even larger than the project on Purgatory Star—the reason why that eldest son on Purgatory Star lost consciousness was because he was sealed by the demon god Vivian. He didn't actually have much damage in his physiological structure. He could live by installing an external brain circuit, but this eldest son was knocked silly by a meteorite. Not only is his brain gone, but even a large part of his central nervous system is rotten. If we were to do an operation, wouldn't we have to dig out a third of the planet?"

As his voice fell, the picture on the holographic projection also changed. The rocks, water, and magma on the planet model all disappeared, leaving only the eldest son's biological tissue, and various different colored color codes marked the state of these tissues and organs. Among them, the brain core and the accessory organs around the brain core were marked with black, which represented necrosis. Even a large number of nerve structures around the brain core were marked with dark red of varying shades: that was a sign of reduced function due to poisoning.

Gunmiao lay on the table, staring eagerly at the tangled mass of tentacles and sarcoma structures in mid-air, raised her hand and said, "It looks like a hairball, meow!"

The corner of Hao Ren's mouth twitched: "Why is this thing here?"

"She was running around in the base. I was afraid that something would happen to her if she ran outside, so I brought her here," Vivian handed a small dried fish to the silly cat to shut her up, and then continued, "Actually, I have an idea."

"Just say it," Hao Ren nodded. "Every idea is useful."

"Zohm... isn't he missing a body?" Vivian tapped the table lightly with her finger. "If we can let Zohm take on the function of the thinking center, how much can the workload be reduced?"

Lily's eyes widened when she heard Vivian's suggestion: "Wow! Bat, your brain hole is no smaller than mine!"

Hao Ren was awakened by Vivian's idea: "Your idea is stable! This can save at least seventy or eighty percent of the project—the most difficult part of building an artificial brain core is this thinking center. The eldest sons are, after all, demigods, and their mental structures are too complex. In fact, the artificial brain on Purgatory Star only simulated a part of the brain core's physiological functions. But if we can let Zohm take over the eldest son's body here, his efficiency will definitely be stronger than the cottage version we made on Purgatory!"

In fact, if there wasn't a layer of reality walls separating Purgatory Star and Tanagrus, Hao Ren would have wanted Zohm to take over that body on Purgatory Star.

"But Zohm is now the ecological supervisor of Tanagrus, he can't leave that place, right?" Nangong Wuyue interjected at this time. "And it's far from Tanagrus here. It always feels inappropriate to dismantle an attached tower of the Crystal Core Research Station and transport it here..."

Because he lost his physical body, Zohm can now only reside in the giant computer of the Crystal Core Research Station in the form of consciousness. In addition to the antenna array and energy unit required for his external connection, the entire system occupies the volume of an entire auxiliary building. To move it over, you would have to cut off about a quarter of the Crystal Core Research Station.

In addition, another point mentioned by Nangong Wuyue is also a problem: Zohm is now taking care of Tanagrus, and he is currently the only surviving rational eldest son in this universe. He simply can't leave.

But Lily thought for a while and suddenly came up with an idea: "How about remote control?"

Seeing the husky girl's big shining eyes, Hao Ren knew that this guy had another flash of inspiration: "Remote control?"

"Didn't we solve the communication interference problem in the X-cluster by relying on building drone fortresses all the way? The communication link from here to the Crystal Core Research Station is smooth, right? We can connect a bunch of artificial nerves to this planet's eldest son, but not build a host, but connect the artificial nerves to the transceiver, and let Zohm use the Crystal Core Research Station's high-power antenna to connect to the transceiver here—just like the drone swarm's thinking network, relying on wireless communication to think, wouldn't that work?"

After Lily finished speaking, she looked at Hao Ren with her big golden eyes, her tail wagging behind her, with a look of "You hurry up and praise me, you hurry up and praise me," her thoughts were simply as easy to understand as a child.

But the solution she proposed was not simple at all—this guy went to Peking University four times not just to eat in the cafeteria...

"The feasibility is quite high. As long as we can ensure smooth wireless communication, it's easy for Zohm's consciousness to extend here," Hao Ren nodded, giving an affirmative answer, and praised the dog girl by the way, "Good idea, very smart."

"That's right, I'm smart!" Lily's tail almost reached the sky. "And I think if this technology is successful, we can do this in the future. As long as we find an eldest son who is still alive, we can directly cut off his brain, and then, before a new brain grows out, install a bunch of artificial nerves and signal base stations for him to let Zohm live in. As long as Zohm can still control it, we can get a large number of network backups for him. We can also give this technology a name, called Cloud Brain..."
