Seeing that it was getting late, Zhang Han cupped his hands and said, "It's getting late, so I won't disturb the Taoist priest anymore. I'll take my leave."
Cao Yi suddenly thought of some details about going to sea and stopped him: "Wait a minute, Pindao has something to discuss with the general."
Zhang Han looked confused.
"It's not convenient here, let's find a place to talk." Cao Yi looked at the dark military tents surrounding him.
Upon hearing this, Zhang Han glanced around and finally stopped at a slightly larger military tent in the southeast: "There is an empty military tent over there."
The two walked over.
Go inside and light the oil lamp.
Seeing that in addition to the bed, there was a soft red lacquered small table, Cao Yi thought of someone: "Is this place prepared for Lu Sheng?"
Zhang Han nodded: "Yes, but we don't need it now."
Cao Yi walked to the soft couch, took off his shoes, got up, knelt down and sat down. I don’t know since when, Cao Yi has become accustomed to sitting on his knees.
Zhang Han also took off his boots and sat down on his knees.
Cao Yi started talking: "The first thing to do when going to sea is fresh water. Fresh water is the water you usually drink. It is very difficult to find fresh water in the vast sea. Even if you find it, it is not easy to store it. So before setting off, the general must load every ship with it." If it is full of wine, the wine will be durable and not easy to spoil. When it rains, you can also use the wine jar to catch the water.”
"Doesn't that mean I have to drink every day?"
Zhang Han, who was full of thoughts about marching men not drinking alcohol, reacted a little bit when he heard Cao Yi's words.
Cao Yi glanced at Zhang Han and said, "It's better than dying of thirst."
Zhang Han was not a stubborn person. He nodded and said, "Han, I will definitely keep your words in mind."
Cao Yi said the second thing: "The sea is vast and the direction is difficult to distinguish. If you are not careful, you may get lost in the endless sea. There is a compass here in Pindao, and the general carries it with him."
After saying that, he took out a compass from the gourd that he bought when he left the world of Xunlong Jue.
Zhang Han took it in his hand, looked at it for a while, and showed an incomprehensible expression.
Cao Yi pointed to the letters above and said: "This represents south, this represents north. If you don't remember, you can use a dagger to carve small seal characters now."
Hearing this, Zhang Han pulled out a dagger from his waist and started carving.
Cao Yi looked at the busy Zhang Han and remembered an object similar to a compass, Si Nan. It is said that it was invented by the State of Zhao during the Warring States Period.
The first mention of Sinan is in "Guiguzi·Mou Chapter 10". The article says: Therefore, the people of Zheng took the jade and carried it in Sinan's chariot, so he was not confused.
Traditionally, Sinan is believed to be in the shape of a spoon.
In the 1950s, an academician surnamed Qian was entrusted by someone to try to make a spoon-shaped Sinan from natural magnets, but he failed because the natural magnets had a small magnetic moment and large friction at the bottom. After that, Mr. Wang Zhenduo used tungsten steel as a restoration object and magnetized it in an artificial electromagnetic field.
Many scholars have questioned that Sinan is not spoon-shaped, and the National History Museum no longer displays the model of Sinan.
"It's carved"
Zhang Han put down the dagger.
Upon seeing this, Cao Yi said the third thing: "If people don't eat vegetables for a long time, they will get sick. Pindao's suggestion is to bring more soybeans and mung beans, that is, squid and swine beans, and soak some at intervals."
This time, Zhang Han nodded without thinking: "No"
Cao Yi thought for a while, and there was nothing else to do, so he said softly: "That's it. General, go back and rest."
Zhang Han got off his knees, put on his boots, said goodbye and left. As soon as he walked outside, he heard Cao Yi's voice again: "I'll come again tomorrow morning. I have something to give to the general."
Zhang Han responded and left.
In the military tent, Cao Yi had a few more healing charms in his hand. I've been very busy recently, so I haven't drawn any symbols, and I don't have many stored symbols.
"I originally planned to select a few disciples, let's talk about it tomorrow."
After Cao Yi finished speaking, he returned to the table, took out the corresponding tools for drawing talismans, placed them on the table, and began to draw talisman.
Healing charms, corpse-killing charms, psychic charms, Lin characters, and thunder charms are all drawn, but the main ones are healing charms.
Because I drew enough, the speed is much faster than before.
In the middle of the night, Cao Yi's expression suddenly changed, and there was not much spiritual energy stored in his body.
Pour out the jade from the purple, gold, and red gourds, and you will find that they are basically all used.
After thinking for a while, Cao Yi suddenly thought of something - Tianxing.
Yesterday, only half of the immortality formation was built on Mount Tai, and there was still half left.
As soon as I thought about it, a sapphire blue stone that exuded bright light and was breathtakingly beautiful floated out of the gourd with a breath of fresh air.
Cao Yi put his hand on it and started the "Gold Liquid Returning Pill Method". I don’t know if the Tianxing has a self-protection function, but it is much slower than absorbing the spiritual energy in the jadeite. Even after absorbing it for an hour, I didn’t absorb much. But the advantage is that the amount is large and you can suck it slowly.
At some point, it was dawn. Cao Yi, who had been practicing for half the night, walked out of the military tent and saw the sun rising from the horizon. Thousands of rays of rays of light shone on the endless wilderness, covering the earth with a golden glow.
"Taoist Master"
Zhang Han came, holding several scrolls in his hands.
Cao Yi glanced at it and asked, "What is the general holding?"
Zhang Han said: "Your Majesty gave me a map and several pictures of God-given things. Your Majesty asked Han to show them to the Taoist Priest."
Cao Yi took Zhang Han to the military tent and looked at them one by one. The map was a map of the Pacific Ocean, much more detailed than the one yesterday. It was a gift from heaven, or rather, potatoes, sweet potatoes, and corn, and the drawings were also very similar.
The first emperor in Chinese history had good painting skills.
After reading it, he closed it and Cao Yi said: "It doesn't matter whether you bring the corn belt back or not. You must bring back the potatoes and sweet potatoes."
Compared with corn, potatoes, and sweet potatoes, which consume too much land fertility and have little advantage in yield, it is more important.
Zhang Han shook his head resolutely: "Since His Majesty has decreed, Han will definitely bring back all three kinds of God-given things."
Cao Yi didn't say anything more after hearing this.
He picked up a wooden box containing a hundred healing charms on the table and said, "It is inevitable that you will encounter poisons on the road. The charms inside can save your life at critical moments."
Zhang Han knew how powerful Cao Yi was, so he took it respectfully: "Thank you, Taoist Master, for the generous gift."
"Go ahead"
Cao Yi waved his hand.
Zhang Han left with the wooden box and several scrolls.
In the following time, Cao Yi did morning lessons and read scriptures.
When it was three poles on the mountain, the soldiers brought breakfast. Halfway through his meal, Cao Yi heard a noise outside, put down his chopsticks, and walked out.
Within sight, a slightly fat alchemist was being beaten by a group of alchemists.
Just as Cao Yi was about to go over, a thin monkey-like alchemist rushed over and knocked down two alchemists, but he was quickly overthrown by the alchemists.
"stop"
Cao Yi shouted loudly.
"Here comes another nosy"
"Take care"
…
The alchemists rushed towards their savior.
Cao Yi knocked dozens of alchemists to the ground effortlessly like swatting flies.
The two alchemists, one fat and one thin, helped each other to stand up, with joyful expressions on their bruised and swollen faces: "Sir, you saved our lives again."
