For Xu Zhi, this was a very fulfilling winter vacation. Whether it was practicing cultivation or revisiting old places, he felt very happy.
In Hua'an No. 1 Middle School, the first class of senior high school has now become the third class of senior high school.
The boys and girls who were fifteen years old have entered adulthood one after another.
His stature, or perhaps his appearance, gradually left his youthfulness and began to mature.
"Brother Xu Zhi, I have decided to enter the Department of Medicine and become a great doctor. If you are sick, you can come see me often."
"Haha, Baobao, um, come on, work hard."
The ugly duckling at the beginning has turned into the little swan today. Gu Baobao is full of youth, has a rosy face, her figure is slowly growing, and her body is toned. Along the way in the physical education department, she received funding from the Xia family and entered a period of rapid development.
In terms of liberal arts, her qualifications are really great. She is a bit like Xu Zhi in junior high school, relying on liberal arts to be able to rank among the top three in her grade.
Being a doctor is a very good profession. Saving lives and healing the wounded is beneficial to both others and yourself.
It's no problem to look for ancient bags when you're sick, but Xu Zhi doesn't want to go there often, so he doesn't curse himself like that.
-------------------
From time to time, on the portal of Dongfang Village, His Majesty Ruiou’s special commission came, inquiring about the progress of the production of refined salt and refined sugar. It was obvious that His Majesty was really concerned about these two crafts.
Although Xu Zhi also wanted to delay some time and strengthen some chips, he really didn't mean to do this.
Yan Jinbai and Gu Yuxi had a great time solving the questions, but it was very troublesome for him to modify it into a process suitable for Casa Civilization.
Some chemical substances, or the structure of machines, the two worlds are fundamentally different, and some professional vocabulary used in recent years made him very troubled.
This is quite like hydrogen sulfide. Xu Zhi can only use the phrase "gas that smells like rotten eggs" to define it.
In addition to modifications, he also went to Huangmao Li Sidan to buy some chemical samples for reference and comparison.
Whether it can be used in production quickly depends on the strength of Casa's research mages and red dwarves.
On the basis of Casa, it is difficult to purify, separate, dry and screen coarse salt and coarse sugar, but it is not difficult to do. In terms of basic people's livelihood science, the vast differences in the world have not led to serious differences.
For example, it was impossible to provide a high-speed rotary centrifuge to Casa. Xu Zhi could not find a company that sold such machines for a while, and it was difficult to bring large machines there.
The concept, basic structure, operation mode, standard parameters, Xu Zhi's unusual diligence in describing it on paper can be regarded as providing some ideas.
"Call Holpus, San Depus, Sandinac, and Nekama. These things give me a headache."
Even though he had lived for thousands of years, Rio still felt that he was confused. There was too much professional and intellectual content that he could not digest at the moment.
Before the actual results are released, Xu Zhi's several flow charts still need to be handled by red dwarves and specialized research mages.
"Sir Zhizhi, can you understand this?"
"Your Majesty," Xu pointed directly at his head and said: "I have a big head now and have been bombarded with this knowledge for a long time. The knowledge from the sacrifice is completely different from what we know. It is very difficult to transform it into something we can understand.
"
"That's really hard on you."
Rio looked at the data that was a finger thick. To generate so much material, the greenskin had to work hard for a long time. No wonder he never responded to his contract.
This made his little thoughts of complaining fade away a lot.
"Sir Zhizhi, what sacrifice did you make in exchange for such a precious material?"
Mister Bama looked at the information and then at the small sample brought by Xu Zhi. This was carefully considered. As long as there are enough samples, the magicians of Casa can trace the path of its formation, explore the development method, and work.
Much more relaxed.
"A large shield from ancient times, more than eight meters long and three meters wide." Xu Zhi made a few gestures, and successfully took out the shield of the patron saint to block the pot.
"This is a trophy obtained from a black dragon's lair in the Urudin Hills. No one can use it, so they gave it to me. The process was dangerous, and I almost got burned to death."
As soon as Xu Zhi mentioned the name of the place, Rio's liver hurt. He fought with Baron Feng Tajin in that chaotic area, but gained nothing. Two archmages were also killed. Unexpectedly, Xu Zhi was so green.
Pi was lucky enough to find the black dragon's lair.
"There seems to be a black dragon cave in the Urudin Hills, which seems to be the home of the black dragon princess Onike."
Misterbama thought for a while and added that he has business with various races and has also traded with the Black Dragon clan, but it is too cheap and difficult to earn. Some old black dragons' eyes were completely fascinated by gold coins and gems.
Every detail is taken care of, and doing business is very difficult.
"I didn't expect that the shield of the patron saint was in the hands of the black loach of Orang Marassa."
After collecting Titan arrows for a lifetime, a new accessory suddenly appeared. Rio felt very depressed. When he had two pieces, he thought the road to collection was very far away, but three pieces were different. It was just one step away. Who could know?
Will the fourth one appear one day?
The Titans in ancient times held high-imitation versions of Titan arrows, which were extremely powerful and could fight black dragons. Although today's Titans are strong, they can no longer reach their previous peaks.
Fortunately now, one piece after another of the Titan's Arrow components has been sacrificed by the green skin, and nothing is left.
"Please make up for it. Your Majesty, if you have some bone breastplate or mental shield from ancient times, you can make up for my little heart."
Xu Zhi thought for a while and then said: "Recently, Archmage Bob has come to make a contract with me again. He wants to challenge a great wizard to a duel and wants to draw me over to be a helper. I am under great pressure."
Compared with other imaginable items, bone breastplate and mental shield undoubtedly rank at the top. One can be matched with the Thor's Helmet, and can be used in reality to break through cognitive barriers. The other can be specially used for defense.
Sandro's mental shock is quite useful.
As a natural magic contract creature, Xu Zhi was reluctantly included in the list of accessories for single combat.
Appreciating the battle of mages is a very insightful thing, but participating in the duel battle is not wonderful. As a turret type of chaotic magic, it is extremely lethal.
Xu Zhi didn't want to make this contract at first, but the old man Bob took out the master stage theory book of life magic as the contract object, which was very tempting. He felt that he was jealous and had to take the risk.
Although the master stage is far away, it is a good thing to make some preparations in advance. Moreover, he now has the guardian robe, so he should not be killed in a few rounds.
"Bone Breastplate" Rio thought for a moment before saying: "If I can catch the skull of Fon Takin, I might be able to dig out one from him. Undead treasures, only the undead will like them."
"Spiritual shield, this is the treasure that we Kasa mages want to destroy the most. Well, when we find one, we almost want to destroy one. I will leave two for you next time." Rio nodded.
Lawful magic focuses on mental control, and mental shields specialize in defending against mental spells, which are inconsistent with the magicians of Casa and have become the most hated defensive treasures of lawful magicians.
"Arch Mage Bob is really fast. If he were to challenge the Arch Wizard, it would probably be Lei Long from Mount Anon, who is an extremely violent fire mage."
"I have a treasure that even fire mages want to smash. Take it and see if Archmage Bob needs it. If you use it well, you should be able to win more easily."
