Chapter 123: When I looked back, I had already embraced the towering giant tree.

The La's eyes glead brightly as he circled the wooden ladder created by Han Cheng. While spinning, he occasionally touched the ladder and sotis grabbed one end, lifting it and vigorously shaking it. The sturdy ladder remained unaffected, showing no signs of loosening.

The more he did this, the brighter La's eyes beca as he discovered a new direction. In the past, the only thods he knew for connecting two things were using ropes or vines that could be used like ropes. However, now, the Divine Child has created a remarkably sturdy ladder without tying with ropes.

For the passionate craftsman like the La, this accomplishnt was comparable to the night of adulthood, when he opened a new door to a whole new world.

"Divine Child!"

Growing more excited as he thought about it, the La released the ladder and respectfully saluted Han Cheng, calling out with excitent.

This act of respect was how the mbers of the Green Sparrow Tribe expressed their admiration for Han Cheng. Even the highly respected Shaman rarely received such treatnt.

The Shaman, too, was observing the ladder. In his perspective, the ladder created by the Divine Child was indeed more exquisite than those tied with ropes. However, it didn't reach the level of excitent that would make him ecstatic.

The La wouldn't be so thrilled for nothing.

This was the cognitive bias brought about by different professions.

For example, the clay tablet that brought joy to the Shaman for inscribing words was just decent in the eyes of the La.

As an enthusiastic craftsman, Han Cheng mostly left the ladder-making process to himself. He only provided guidance when there were certain aspects the La didn't understand.

It's worth ntioning that Han Cheng had already created a ruler.

With the increasing production of various items, there needed to be certain standards to ensure the aesthetics and easy replacent of damaged parts. Additionally, Han Cheng wanted a relatively accurate asuring tool.

The ruler was simple to make. He found so straight wooden sticks and removed the outer bark, leaving the white inner part. He estimated a length of ten centiters first. Then, using this ten-centiter piece as a standard, he extended it step by step to create rulers of one ter, one and a half ters, or even two and a half ters.

After estimating the distance of ten centiters, he evenly marked the ruler with zero to ten, with numbers labeled at each centiter. After finishing the markings, he rubbed a bit of wood charcoal on them, instantly making the initially unclear marks clear.

Likewise, using this ten-centiter wooden stick as a reference, he accurately marked other sticks of different lengths to the centiter. He made another small vertical mark in the middle of each centiter, indicating half a centiter.

For the current Green Sparrow Tribe, accuracy to the centiter was already sufficient. Although Han Cheng's estimated ten-centiter distance might differ sowhat from the exact ten centiters in the future, he wasn't worried. His standard would be accurate as long as he could maintain this standard and ensure that the rulers produced later were the sa length as the initial ten-centiter piece.

So, Han Cheng took great care to preserve the initially asured ten-centiter wooden segnt.

After discussing the importance of this tool with the Shaman and stressing its significance, the Shaman, not entirely grasping the Divine Child's words, placed it on the sacred stone tablet in front of the totem pole, where the feathered crown and bone staff were kept. This place was the holiest and safest in the entire Green Sparrow Tribe.

The Shaman didn't fully understand why the seemingly ordinary wooden stick suddenly beca so important, but since the Divine Child regarded it with such gravity, it couldn't be wrong.

Manufacturing rulers was a ticulous task that couldn't afford any negligence. To craft these tools properly, Han Cheng dedicated several days, working continuously, before finally completing the task.

However, rulers made from wooden sticks had shortcomings, particularly in length. They were suitable for asuring shorter objects, but they beca extrely inconvenient to use once the length increased.

Therefore, the tape asure ca into existence.

The materials for the tape asure were simple

twisted ropes.

Han Cheng cut two lengths of rope, one asuring ten ters and the other five ters, both asured using the previously standardized ruler.

Starting from the beginning, every ten centiters, he tied a small knot with a single strand of rope grass. At the one-ter mark, he used a thin rope made by twisting two strands together and tied a large knot. This perfectly solved the issue of leaving markings on the rope.

These two tape asures were mainly used to asure large distances, such as the foundations of the courtyard wall and the gaps between house beams. They didn't require extre precision, and markings every ten centiters were sufficient.

The finished tape asures were wrapped around short wooden sticks. When in use, they could be pulled out; when not, they could be wrapped around the sticks again.

To familiarize the tribe mbers with the concept of rulers and teach them how to use these tools, Han Cheng put considerable effort into explaining, using nurous words to gradually make them accept and understand what rulers were and how to use them.

In understanding and using rulers, the fastest learner was not Stone, who had an innate talent for Chinese and characters, but La.

This might be related to his engagent in weaving fish traps, rafts, fences, and other items over the past year. Since these things required specific dinsions, his frequent exposure naturally made him comprehend and use rulers faster than the average person.

Next were Hei Wa, the tribe's top potter, and then Shi Tou.

Among the people in the tribe, Han Cheng admired La the most.

Due to the injury to his leg, he had experienced the sorrow of becoming a burden. Therefore, when Han Cheng appeared and brought him so hope, he clung to it desperately.

In this way, after more than a year had passed, looking back, it would be surprising to find that he had acquired so much, much of which far exceeded the abilities of an ordinary person.

La held a piece of charcoal in one hand and a one-ter ruler in the other, gesturing and muttering softly as he laid it flat on the ground against a wooden post. After a while, he would leave marks on the wooden post using the black charcoal.

He appeared sowhat like a woodworker from the future.

He was finding the points where he needed to create mortises.

To manufacture a wooden ladder, the mortises on the two side pillars used to insert the crossbars had to align; otherwise, when it was ti to fit the crossbars, they would either not fit or be loosely attached.

He was imrsed in his work, unaware of the approving look in Han Cheng's eyes as he stood on the side.
