Han Cheng was preparing for a significant move, and while outside, Eldest senior brother and the others, who had just received a kick, were feeling much better than before.

After years of living in the tribe, everyone had grown accustomed to the Divine Son's temperament. They had also grown used to being kicked by him.

So much so that if someone failed at a task and didn’t receive a kick from the Divine Son, they would feel strangely uneasy.

Today, although the Divine Son hadn’t given a definitive answer about not tearing down the wall, he had at least postponed the matter. That was enough to ease some of their concerns—for now.

That night, most of the people in the tribe didn’t sleep soundly. Some even woke from nightmares, only to sigh in relief upon realizing the wall was still standing.

But that sense of security vanished when they recalled the large "DEMOLISH" character the Divine Son had written outside the wall earlier that day.

Although the Divine Son had promised to build a new, taller, and stronger wall after tearing down the current one, many people still felt uneasy.

After all, constructing a wall could not be done overnight. From the time the old wall was torn down to the completion of the new one, the tribe would be without its protective barrier for a long period.

And when they thought of the horrors they had seen in their dreams just a while ago, sleep became an impossible luxury.

Han Cheng was lying on the heated brick bed inside his room, staring into the darkness.

After helping Little Pea relieve himself into a clay chamber pot, Han Cheng found himself too preoccupied with his thoughts to sleep.

It was time to shock these people!

He lay there thinking through his plans for a while longer. Once everything cleared his mind, sleepiness finally overcame him, and he drifted off.

The following day, as soon as he woke up, Han Cheng went straight to find the paper that Shi Tou had recently made.

Of course, it wasn’t because he urgently needed to use the toilet. He needed the paper for something far more critical—drawing!

That’s right—drawing!

This was the move he was going to unleash.

Last night, he had already made up his mind. He was going to draw out the layout for the tribe!

Doing this allowed him to visualize everything more clearly and make better planning decisions.

His goal was to design a new settlement that was practical and aesthetically pleasing.

Unlike the current chaotic layout, where buildings were erected wherever there was space, he wanted the new village to be well-organized and structured.

And most importantly, once the blueprint was complete, he could adequately stun these ignorant villagers!

They thought their current way of living was acceptable, but that was only because they hadn’t seen anything better.

Once they saw the plan laid out before them, they would surely change their minds!

Han Cheng thought smugly to himself.

The paper in the tribe wasn’t huge—each sheet was about 1.2 meters long and 60 centimeters wide.

Given Han Cheng’s rather crude drawing skills, such small sheets weren’t enough to contain the entire blueprint for the Green Sparrow Tribe’s redesign.

So after flipping through the paper, tearing off a few sheets, and taking a quick trip to the toilet, Han Cheng returned and called for Shi Tou and Lame.

He instructed Lame to build a 1.2-meter-wide by 2-meter-long frame for drying paper.

Compared to the endlessly inquisitive Shi Tou, who kept asking what this giant sheet of paper was for and what a blueprint was, Lame was far more efficient—he just got to work without a word.

Looking at Shi Tou, who kept bombarding him with questions, Han Cheng suddenly had the urge to tell him a story—about his neighbor who lived to be ninety and still had a strong, healthy body…

But worried that shutting him down would kill his enthusiasm, Han Cheng had no choice but to endure Shi Tou’s endless barrage of questions and explain things to him bit by bit.

Finally, when Lame finished making the oversized paper-drying frame, Han Cheng shoved it into Shi Tou’s arms and urged him to hurry up and start making paper. As for Han Cheng himself, he took the first chance to escape.

Now, he truly understood why Tang Seng had subdued Sun Wukong.

Watching the Divine Son hurriedly leave, Shi Tou blinked with a bit of grievance. He still had so many questions: why did the Divine Son run away so fast?

Though he felt a little disappointed, he still carried the newly crafted frame and ran off to make paper.

After all, the Divine Son had just told him many things he had never heard before, which only made his curiosity burn even stronger.

So he wanted to finish making the high-quality paper as soon as possible and then see what the Divine Son was up to.

A workman must first sharpen his tools to do his job well.

Despite practicing for a few years, Han Cheng still lacked the best drawing skills. If he wanted to create a blueprint that would truly impress the tribe, he needed proper tools.

Once he had walked safely away, Han Cheng stealthily turned back.

After ensuring Shi Tou was already busy with paper-making, he quietly returned and found Lame again.

He asked Lame to craft a set of tools—rulers and compasses.

As for a right-angle triangle ruler, that was easy enough to make as long as he had a compass.

He could always form a right triangle by using the diameter of a circle as the hypotenuse and picking any point on the circle’s edge.

He could easily construct an isosceles right triangle if he marked two perpendicular diameters within the same circle.

Such tricks were no challenge for Han Cheng.

Taking the compass and ruler, he quickly sketched a few lines on the paper, and two different right triangles appeared. As for crafting wooden rulers based on these sketches—that was Lame’s job.

With the paper and tools sorted, the next step was up to Han Cheng himself.

His next task was to make pigments.

Given his artistic limitations, simple charcoal sketches wouldn’t be enough. If he wanted to shock the tribe's people correctly, he needed to add color to his drawings.

It was the same principle as a mediocre chef relying heavily on spices to make food taste better.

Fortunately, there was no need to worry about getting pigments. Though Han Cheng was a humanities student, he knew that red, yellow, and blue were the primary colors from which all others could be mixed.

Blue pigment was no issue—"Green is derived from indigo but is bluer than indigo; ice is formed from water but is colder than water." This ancient saying already hinted at a method to extract blue pigment.

People often say, "Master math and science, and you can travel the world without fear." But as it turned out, mastering classical literature was just as valuable.

So far, Han Cheng has already gleaned three practical techniques from ancient texts: rammed earth construction, wooden wheels, and blue pigment extraction.

As for yellow pigment, that wasn’t a concern either. Near the tribe, there was a patch of gardenia plants…
