The next morning, accompanied by crisp bird chirps, Su Bai slowly opened his black eyes.
He stretched lazily, looked around, and finding the fox eared girl absent. He called out in his mind, [System, check in and open the Assistance Package.]
[Ding! Congratulations Host, check in successful!]
[Ding! Congratulations, Host has received Low Grade Assistance: one nail care tool kit.]
Su Bai weighed the small box in his hand, murmuring. “Well, this is useful.”
He opened the box and found quite a variety of tools inside – ones for trimming toenails, nail filing, and ear cleaning. The tool kit was truly complete.
“Well, look at this.” Su Bai picked up the ear cleaning tool and started using it. The sensation was naturally quite pleasant.
It had been a long ti since he had properly cleaned his ears, this tool ca at a good ti.
A few minutes later, after Su Bai finished taking care of his ears and nails, the fox eared girl ca in.
“Shaman, you woke up so early.” Yu Ying’s soft voice called out.
*ow~*
She had gone to the greenhouse early in the morning to check on the wheat’s growth. She also took Su Bai’s laundry to wash them, and then went to check on the sheep pen and cattle pen. Rolly had followed along,
Cats were sensitive animals. When Yu Ying got up in the morning, Rolly had risen with her and stuck close to her.
“Sleep early, wake up early.” Su Bai poured himself a cup of water.
Last night, for so unknown reason, he felt tired for the first ti. Previously, he would just go to sleep on his own, not because he felt tired.
At first, he thought his Physique had changed and specifically checked on his Attribute Panel, but found his Physique was still fine. As for why he felt tired, it was probably a normal occurrence. However, it was just so rare for him that he found it odd.
“I’ll prepare breakfast for you, Shaman. You can rest a bit more.” Yu Ying turned to prepare the food.
Su Bai sat down and looked through the glass manufacturing guide. The cent houses were now mostly built. So, glass now needed to be made.
Looking at the dense content in the book, he sighed. [This won’t be easy!]
Glass was not sothing that can be casually manufactured by hand. It was a genuinely difficult task.
Besides the difficulty in collecting materials and getting the proportions right, the most important part was the manufacturing process.
Moreover, the materials for glass were not easy to collect. Too many things were needed.
“Shaman, what’s wrong?” Yu Ying heard Su Bai’s murmuring.
“Nothing, I was just thinking about how to make glass…” Su Bai shook his head.
Yu Ying nodded – she did not understand the word ‘glass’, so she just continued preparing breakfast.
“I would need quartz sand, soda ash, listone, and more to make glass. So are easy to find, but others…” Su Bai muttered.
Glass was generally made from various inorganic minerals like silica sand from quartz, borax, boric acid, barite, barium carbonate, listone, feldspar, soda ash as its main materials. Additional auxiliary materials were also needed. Its main components were silicon dioxide and other oxides. ŕáꞐő𝔟ĚS
Making glass was certainly not simple. Just gathering the required materials would take quite so ti.
“But these pictures in the book look familiar…” Su Bai murmured.
The pictures in the glass manufacturing guide were simple, just diagrams of raw materials with so annotations.
The material nas were the sa as on Earth, though their appearance was slightly different.
[Perhaps they looked different in this era, but their actual chemical structure is the sa?]
“Wait!” Su Bai put down the book and went to search through several large boxes, murmuring. “I rember the Old Shaman left many stones, maybe sothing here will be useful.”
After the Old Shaman passed away, he had taken so ti to sort through the boxes and found many strange stones.
His knowledge base was not that extensive though. So, he only recognized one-third of the stones, with most remaining unidentified.
After searching, various stones appeared on the table, different in colour and size.
“No wonder they looked so familiar… the Old Shaman had them all along…” Su Bai excitedly said.
He did not know why the Old Shaman had these stones. [People of this era probably do not know anything about minerals. Even if they know so stones are hard enough to make weapons, no one should be aware of their true uses. So stones could be used to make rcury, so for dicine, others for accessories, and so on. These products are all unfamiliar to those of the Primitive Era. So, why did the Old Shaman bother collecting so many strange stones when he did not understand their uses?]
[It is even stranger that when the Tribe was attacked by the Black Snake Tribe, they still managed to take these stones away while escaping? This suggests these stones are important… but for what?]
“Shaman, why did you take out all these stones again?” Yu Ying ca over with a bowl of noodles.
“They will be very useful/” Su Bai smiled and started eating the noodles.
He quickly finished eating and continued examining the stones.
The cent houses were being built faster and faster, and glass needed to be fired in ti. Otherwise, the reserved window spaces would be problematic, and it would be colder when it rained.
[With these ingredients, we need to follow the designed formula. We need to properly weigh and mix the various materials evenly to complete the proportions. Unfortunately, we still have not developed scales…] Su Bai frowned. [Haa… Trying to make glass in the primitive era is truly not easy. The tools alone are a major limitation.]
“Okay, let’s take things step by step. Let’s make a balance scale first. Otherwise, I would not be able to proceed with a ton of other things.” Su Bai murmured.
Making a scale was not difficult. It was very simple and could be done in about ten minutes.
The needed materials included a fra with grooves at both ends, two cups or containers of the sa size and weight, and vines.
Make two identical small holes near the rim of each cup, with the holes parallel to each other. Then cut two sturdy vines of equal length.
Thread one vine through both holes of each cup and tie it securely – when done, the cup should look like a small bucket.
The final step was hanging the cups in the grooves at both ends of the fra, with both cups at the sa height.
If uneven, adjust the rope length to complete the balance scale.
The main principle of making a balance scale was the lever principle – with the fulcrum allowing rotation under equal force.
