After taking note of some of Ziyang Taixuan's questions, Yang Tian deliberated and asked some common knowledge questions of this world.
This made Huie and Chanchan look at Yang Tian as if they were looking at an alien.
Because Yang Tian had accepted the mission, the Runes Division still arranged a place for Yang Tian even though they thought it was impossible.
It was a simple and crude room, but it had been tidied up by Karcha.
Karst was determined to follow Yang Tian because he felt that Yang Tian's future was limitless. When Yang Tian rises in the future, he would be able to enjoy all the benefits he could get from Yang Tian's fingers.
He rested for a night.
The next day, Yang Tian did not go to Ziyang Taixuan's room. Instead, under Karcha's guidance, he went to the bank and exchanged ten Life Crystals for Lice Crystals.
When Yang Tian was in the mine, the Louse Crystal he collected was the size of a grain of rice and was in the form of light purple granules. The Louse Crystal that the bank exchanged for had been processed using a special method and had two different shapes.
One was long, about five centimeters long and as thick as a finger.
The other was round, twice the size of a grain of rice.
One Returnance Life Crystal could be exchanged for fifty long Lice Crystals or two hundred and fifty round Lice Crystals.
In other words, fifty round Lice Crystals were equivalent to one long Lice Crystal.
The long Lice Crystals were usually used for large transactions, while the round Lice Crystals could be used to buy items of lower value.
Yang Tian exchanged for five hundred round Lice Crystals and four hundred long Lice Crystals.
Other than exchanging for Lice Crystals, there was also a special paper currency that could be used in the entire Flame Domain.
Most ordinary humans in the clan used paper currency.
Cultivators were rich and had storage tools, so it was more convenient for them to use Lice Crystals.
But for ordinary humans, without storage tools, Lice Crystals would fall off easily and were inconvenient to carry around.
The wages of Karst and the others were also paid in paper money.
Of course, they could also exchange paper for Lice Crystals of equal value.
Karst had a storage ring with a small storage space. Every time he received his salary, he would immediately exchange it for lice crystals.
He had stayed in the Hui E Family for more than ten years, but the number of lice crystals he had accumulated wasn't even one-tenth of what Yang Tian had.
There were a total of 18 Life Crystals. Yang Tian exchanged ten of them while the remaining eight were reserved for the Little Blue Dragon.
Although the Little Blue Dragon had consumed eight Returnance life crystals and the energy it had obtained was not enough for it to break through, it was still better than nothing.
For example, if he was tired after a battle, he could use it to replenish the energy of the Little Blue Dragon.
Hearing Yang Tian telling the Little Blue Dragon that he would leave eight Life Crystals for it as snacks, Karcha was envious. The Little Blue Dragon responded to Karcha's proud gaze.
Every time he looked at Karst, the Little Blue Dragon would think of that fatty from Juliang City.
"Actually, before the beast tide, the clan's land was very prosperous. There were shops everywhere, and the people on the streets were all huddled together …"
As they walked, Ka Cha described the scene of the beast horde to Yang Tian after seeing the ruins around them.
"The clan's land is so big, and there are so many people. What do they eat?" Yang Tian asked curiously after Karst finished.
Karst said, "Farming!
A small Lice Crystal can be dissolved in water using a special method. In a month's time, a 'Strong Grain' can produce enough grain for a family of three.
As for other food, some of them are grown like Strong Grains, some of them are harvested by cultivators from faraway forests, and some of them are obtained from hunting exotic beasts. "
Yang Tian finally remembered that when he ate, there would be a large piece of food that was slightly smaller than a football. It tasted like a sweet potato.
So this was Strong Grain.
Strong Grain had a purple outer shell. After peeling it off, there were snow-white crystals inside, just like pearls.
They were soft and soft in the mouth, and had a sweet taste.
An ordinary person would need to eat about two of them every day to maintain the energy needed for a day's work.
"Quickly take me to have a look!" Yang Tian urged Karst out of curiosity.
Karst nodded, and led Yang Tian to the center of the clan's land.
After passing through the fourth wall, they saw a Strong Grain Tree that was thicker than an adult's thigh.
The leaves of this kind of tree were very thick, light green, and palm-sized. The trees were densely packed with Strong Grains. There were at least several hundred Strong Grains on each tree.
The tree's skill bar was very hard. It was thinner than a finger, and more than ten Strong Grains could be hung on it. It looked very strong.
This was probably the origin of this tree's name!
The Strong Grains produced by this tree could support an adult for at least half a year.
Looking at the roots of the trees, they were surrounded by bluestones. There was black soil inside, and it was obvious that it had just been loosened.
"What are the conditions for this kind of tree to grow?" Yang Tian asked curiously.
Karst said, "It doesn't have high requirements. It only needs sunlight for a moment every day.
However, it is afraid of the cold. "
"Can it be grown underground?" Yang Tian asked again.
Karst said, "If it can receive sunlight, it will be okay."
The 'sunlight' here was the same as the sunlight on Earth. It was the light from the stars in the sky.
After seeing this kind of tree, Yang Tian felt that the people in this world were very fortunate. They didn't need to worry about food.
No wonder people didn't get sick. This food was truly green. It absorbed the energy of the Lice Crystal to grow. When ordinary people ate this kind of food, it was the same as indirectly absorbing the energy of the Lice Crystal.
Although the amount wasn't much, it could still keep people healthy.
In the next few days, Yang Tian wandered around the clan's land.
Because the design of the underground city had to consider the production and living conditions of the people.
Just like the Strong Grains, the construction of the underground city had to use runes to project the light of the stars into the city. Only then could the Strong Grains grow.
…
Seven days of the ten days agreed with Huie Miaomiao quickly passed.
On the eighth day, Yang Tian went out for a walk and then went to Ziyang Tai Xuan's' workshop '.
When Yang Tian went out these days, although only Karst followed him, there was someone watching Yang Tian all the time.
At this time, the strange program had finished the design.
Yang Tian entered Ziyang Tai Xuan's room. There was no one inside.
After searching for a long time, Yang Tian finally found a few large, blank pieces of paper.
The clan's land model in the middle of the room had been removed. Yang Tian could use it to draw.
Of course, the drawing process was a strange program that controlled Yang Tian's body to draw on the blueprint.
Yang Tian and Karst had just laid out the paper when the door was pushed open.
The first to enter was Ziyang Tai Xuan, followed by an unfamiliar old man in a red robe. Then came Huie Chanchan, followed by a large group of people from the Rune Division.
Ziyang Tai Xuan didn't say anything. The unfamiliar old man came in front of Yang Tian and said to Yang Tian, "Don't hurry to draw the design. Defeat me first. I want to fight with you!
If you lose, leave the Rune Division immediately.
If you win, I will listen to you. "
"Good!
Good! "
Huie and Chanchan clapped their hands and cheered.
Yang Tian scratched his head and stared at the unfamiliar old man with wide eyes … What was going on!
