The ten-year temporary management term for the Tongtian River had ended, and Immortal Master Erlang left his duties to Third Crown Prince of the Dragon, leading his troops back to Wanling City.
In front of Sun Wukong, Lord Lao Zi of the Great Monad handed over the Jade Seal, symbolizing the lordship of the Earth Palace, to Immortal Master Erlang.
"Thank you, Lord."
Immortal Master Erlang gave his thanks with a clasped fist.
"I'm glad to be relieved as well."
Lord Lao Zi said cheerfully, having long wished to put down the burden.
Born with the Heavenly Eye, Immortal Master Erlang had the ability to see the minutest detail, which made him perfect for the role of supervision.
With the matter settled, Lord Lao Zi took his leave.
Immortal Master Erlang was concerned about the Plum Mountain Brothers and inquired Sun Wukong about their recent situation.
"They are all doing well; you needn't worry."
Sun Wukong said with a smile, "After the long journey you've had, why not have a meal here first?"
Seeing that Immortal Master Erlang was still somewhat concerned, he added, "After the meal, I shall take you to see them."
"Many thanks to the Great Saint."
Immortal Master Erlang quickly expressed his gratitude.
"Do you have any special food you wish to eat?"
Sun Wukong asked.
Without hesitating, Immortal Master Erlang replied, "Tofu."
"Tofu?"
Sun Wukong showed a puzzled look.
"It's what my troops wish to eat."
Immortal Master Erlang said with a smile.
The Erlang's infantry following him promptly answered, "Tofu is crucial to us; no other taste compares to its deliciousness."
After staying by the Tongtian River for ten years, they truly missed the tofu from Huaguo Mountain.
"In that case..."
Sun Wukong, though not fully understanding, still agreed and instructed his servants, "Cancel the order from the Bull Demon King and arrange for some tofu from the restaurant."
Unexpectedly, no sooner had the words left his mouth than the Erlang's infantry inside the hall burst into uproar.
"The Bull Demon King's noodles!"
"No need! Great Saint, let's just have the noodles after all!"
They said one after another.
Sun Wukong turned back in surprise, "Didn't you say tofu was crucial to your lives?"
"Upon seeing the noodles, we can forgo our lives."
The Erlang's infantry answered.
Sun Wukong gladly agreed.
After a hearty meal, Sun Wukong made arrangements for the Erlang's infantry and then took Immortal Master Erlang to find the Plum Mountain Brothers.
They left Wanling City, flew over two large mountains, and came to a city under construction.
"Eh? What is being built here?"
Immortal Master Erlang asked.
"Academy City."
Sun Wukong answered.
This was the construction site for Academy City; they had gone from planning to breaking ground in just a few months.
Immortal Master Erlang saw that the drainage system underground was already in place, the foundations for some roads and houses were laid, and some areas had already had houses built.
"It's so fast, we only talked about building it at the turn of the year."
Immortal Master Erlang expressed his amazement: "And now it's already taking shape."
"They have experience."
Sun Wukong said with a smile, "With Immortal leading the team here, naturally, the construction is even faster."
Immortal Master Erlang soon saw the Plum Mountain Brothers, who were leading a group of young people in laying down the tracks, busy as bees.
Approaching them, the Plum Mountain Brothers hurried forward to greet them.
"What are you working on?"
Immortal Master Erlang looked over the tracks.
"This is the urban circuit railway."
The Plum Mountain Brothers replied.
The technology for the new mode of transportation had been completed, and now it was undergoing the trial and testing phase.
The Academy City currently under construction provided the perfect testing ground.
The trial track had been laid out, encircling the entire Academy City.
Beneath the tracks, mysterious Runes were carved, all shining brightly.
Immortal Master Erlang opened his Heavenly Eye to see that the Spiritual Power flowing underground was continually charging those Runes.
"The design of these tracks is indeed ingenious; taking them away would indeed be a waste of talent..."
So thought Immortal Master Erlang.
He could tell that the Plum Mountain Brothers really enjoyed their job, so he gave up on the idea of having them join the Earth Palace.
"Great Saint."
Immortal Master Erlang turned to Sun Wukong and said, "I heard that a thousand miles..."
He stopped speaking, afraid that Sun Wukong wasn't free to listen to what he had to say.
The Great Saint really is popular.
Immortal Master Erlang thought.
A group of girls surrounded Sun Wukong, chirping like a happy flock of sparrows.
"Great King, why are you here?"
"Why don't you come to see us?"
The Spider Demons, curious and asking all sorts of questions, appeared out of nowhere.
Sun Wukong, bombarded by questions, regretted not having come in disguise: "What are you doing here?"
"We are looking for Kite Brother!"
The Spider Demons said.
The Kite Brother they were looking for was Elder Jin Chan.
They all spoke at once, and after a while, Sun Wukong finally understood.
Apparently, Elder Jin Chan was supposed to teach them today, but he went out for a drink of water during the class and never came back, so the Spider Demons climbed over the academy's wall to look for him.
"Kite Brother is so much fun, he always loves to play hide and seek with us."
The Spider Demons said with giggles, "We look for him every day."
He was just lost.
Sun Wukong thought, but could the Spider Demons really find Elder Jin Chan?
As soon as the thought crossed his mind, the seven little ones suddenly seemed to discover something and turned their heads to look in one direction.
"Found him!"
They cheered and ran toward the direction of the forest.
Curious, Sun Wukong looked in the same direction and soon saw the Spider Demons returning with a rice dumpling wrapped up in spider silk.
"Kite Brother, we won! You be our kite!"
The Spider Demons said, holding up the dumpling.
Sun Wukong watched as they skillfully prepared to throw Elder Jin Chan into the air. Elder Jin Chan, upon seeing Sun Wukong, quickly sent a plea for help with his eyes.
Sun Wukong glanced at the seven Spider Demons and decided to pretend he didn't see, turning back to look at the rail track.
Just a moment of not paying attention, and the scene on the track surprised him.
General Guo Shen was lying on the track again.
The Plum Mountain Brothers were about to demonstrate the efficacy of the rail tower to Immortal Master Erlang.
"Wait—"
Seeing that the Runes weren't activated yet, Sun Wukong intervened, "Why involve General Guo Shen again?"
"The test carriage was damaged from the impact, Great Saint."
The Plum Mountain Brothers answered, "Now, only General Guo Shen is left."
Sun Wukong frowned.
"No problem, Great Saint."
General Guo Shen said, "This track is circular; given my light weight, it's impossible for me to derail."
Sun Wukong looked skeptical, but since General Guo Shen himself said so, it was hard for him to object.
Dressed in Rune Clothes, General Guo Shen levitated on the track, starting to accelerate slowly.
"The speed control really has improved."
Sun Wukong thought to himself.
General Guo Shen's speed was gradually increasing, smoothly gliding into the distance.
However, at that moment, the Spider Demons flying kites spotted General Guo Shen and suddenly jumped onto him.
"This is bad—"
A cry of alarm came from the Plum Mountain Brothers.
They couldn't turn off the track in time, and when the Runes below sensed the increase in weight, they ramped up the thrust. General Guo Shen whooshed and skimmed along the track.
"Aaah!"
The girls' screams sounded a bit excited.
Sun Wukong and Immortal Master Erlang watched the scene in a daze.
The Heavenly Book spoke of a form of entertainment called "roller coaster," which seems to be just like this.
Sun Wukong thought then watched as General Guo Shen swiftly shrank to a dot in the distance, still pulling a high-speed flying kite in the sky.
"The weight of the General now..."
He suddenly remembered to ask, "Could it derail?"
The Plum Mountain Brothers wiped their sweat.
"Shouldn't... I guess..."
Their voices lacked confidence.
