Chapter 78: The Great Gathering in the Underground City

Sang Chu, Mu Xue, and Sang Jingwen went straight into the underground city.

At that moment, Grandma Lin was tending to the plants by herself. When she saw them coming, she greeted them with a big smile. “Sangsang, you’re back!”

“Yes, Grandma, I’m back.”

Grandma Lin looked at her granddaughter and Mu Xue, smiling as she said, “There’s nothing to worry about here. It’s very safe, so you can rest easy.”

Sang Chu glanced around the dim underground city. Even though she’d already installed a lot of lighting, the place was just too big.

She took out a dragon pearl, thinking she’d need many to light up the whole place, so she’d prepared to use all of them for the underground city. But unexpectedly, as soon as she took out one, the entire underground city lit up as bright as day.

Mu Xue’s eyes widened. “Wow, this pearl is so bright!”

The sudden burst of light stung Grandma Lin’s eyes, and she quickly shielded them with her hand. “Sangsang, what is that?”

Mu Xue was also curious. “Yeah, what is it? How is it so bright?”

Sang Chu had the construction robot install a holder for the dragon pearl in midair, then placed the pearl on it. “This is a dragon pearl. I thought I’d need a lot to light up the place, but it turns out just one is enough for the whole underground city.”

Suddenly, Mu Xue grabbed Grandma’s hand and ran into one of the houses. She opened the window and shouted excitedly, “Sangsang, Grandma, Brother Wen, it’s so bright in here too! It’s just like daytime!”

Hearing her, Sang Chu and Sang Jingwen couldn’t help but laugh. They supported Grandma and walked over to where Mu Xue was.

Once inside, they realized Mu Xue was right.

Sang Jingwen said, “It really is bright!”

Mu Xue asked, “Sangsang, can this dragon pearl keep shining forever?”

Sang Chu nodded. “Yes, it can. But when it’s not in use, it needs to be soaked in spiritual spring water. I’ll head out now and bring back some spiritual soil and spring water. I’ll finish setting up the underground city first, and then I’ll take care of the rest.”

“Okay, Grandma, Brother Wen, let’s hurry up and go!” Mu Xue was very excited. It felt just like before the apocalypse—even though they were underground, life now was almost no different from before!

Sang Chu had the construction robot create planting beds, then dumped the spiritual soil she’d dug from Butterfly Valley onto the ground. The robot quickly finished the setup.

At this time, Mu Xue took out some watermelon seeds and looked at Sang Chu. “Sangsang, should we transplant these plants now?”

“Sure.”

The four of them worked together, planting the seeds. “Grandma, you just need to keep an eye on these. As long as they can grow on their own, it’s fine.”

“Don’t worry, I’ll take good care of them!” Grandma Lin said confidently.

Sang Chu smiled and then placed a water spirit bead into the pool the robot had just built. “Grandma, you can use this water for daily needs and even drink it. It’s all spiritual spring water—it’s good for your health.”

Seeing the water and soil, Grandma Lin, who had spent most of her life farming, was very happy. “Good, good, I understand!”

Mu Xue squatted by the pool, watching the robot build several water troughs. She asked, “Sangsang, why are you making so many water troughs?”

“I’ve also dug a well. The pool is for Grandma’s daily use. The water troughs are connected to the fields, so when we need to water the crops, we just open the valve and the water will flow out. The well water is for drinking and other needs.”

Grandma Lin pointed to a sealed pool nearby. “Sangsang, what about that one?”

“Grandma, that pool is for soaking the dragon pearls. The pearls need to be kept in spiritual spring water to keep shining. Otherwise, they’ll lose their light. Grandma, I might not always be in the underground city, so I’ll have to trouble you to take care of them.”

Grandma Lin patted her hand. “It’s no trouble at all. I’m already very happy that I can help. I know you’re busy, so I’ll guard this place well. No matter what happens, I’ll protect it. You don’t have to worry about anything!”

Mu Xue and Sang Chu leaned against Grandma, one on each side. “Grandma, you’re the best.”

Watching this scene, Sang Jingwen felt like he’d gone back to his childhood. At that moment, Lu Minli contacted him. “Sangsang, Minli says she’s already picked up the ability user and is on her way here. It’s just that it’s too bright now, so she’s using off-road mode and might be delayed a bit.”

Sang Chu said, “That’s fine. While we have time, there’s something I want to talk to you about.”

Earlier, she’d had Little Guang (the light-type robot) set up the cultivation chamber from the demon realm in the underground city. She led Sang Jingwen to the chamber.

“Brother, Grandma, this is something I got from the demon realm. Even though I don’t have spiritual roots myself, as long as you have even a trace of spiritual root, you can find a suitable cultivation technique and method. Who knows, you might even awaken an ability. Even if you don’t, you’ll be immune to all those weird viruses after the apocalypse, as long as you’re an ordinary person.”

What she meant was, even if you don’t have energy, you won’t suddenly die from exhaustion.

What she feared most now was that her brother or grandma would suddenly die because they weren’t ability users or were too weak. If that happened, everything she’d done would be meaningless.

Sang Jingwen looked at the strange chamber and hesitated. “Sis, this…”

“Sangsang, I think I’ll pass. But your brother should try.”

Grandma Lin felt she was too old. Even if she could cultivate, she probably wouldn’t get far. It was better to let Sang Jingwen try.

He didn’t know that ordinary people could suddenly die, and Sang Chu didn’t plan to tell him. After all, she wasn’t sure if her brother or grandma could cultivate.

“Grandma, you don’t have to do anything. Anyone can use this. I had the robot set it up. You and my brother just need to sit on those white seats and close your eyes.”

Grandma Lin hesitated. “This…”

Sang Jingwen walked over and sat on the white seat. “Grandma, Sangsang, Xiaoxue and I all need you. Let’s do it together!”

Mu Xue chimed in, “That’s right, Grandma. I’ve done so much just so our family can always be together. Come on, let’s try!”

Looking at her grandchildren, Grandma Lin sighed. “Alright, but I won’t get my hopes up.”

Sang Chu said, “Don’t worry, Grandma. If it works, great. If not, I’ll go first.”

After Grandma Lin and Sang Jingwen sat down, Sang Chu immediately activated all the spiritual roots and guided the spiritual energy.

As long as Grandma Lin and Sang Jingwen had even a trace of spiritual root, under the guidance of the spiritual energy, they’d be able to find a suitable cultivation method.

But as time passed, there was no progress at all.

Mu Xue anxiously looked at Sang Chu. “Sangsang, Grandma and Brother Jingwen…”"
