Seeing that it was getting late, Zhang Han bowed and said, "It's getting late, so Han won't bother Taoist Master, say goodbye."

Cao Yi suddenly thought of some details about going to sea and stopped him, "Let's go, I have something to talk to the general."

Zhang Han showed doubts on his face.

"It's not convenient here, so find a place to talk." Cao Yi looked at the dark military tent around him.

Upon hearing this, Zhang Han glanced at him and finally stopped on a slightly larger military tent in the southeast: "There is an empty military tent over there."

The two walked over.

Enter and light the oil lamp.

Seeing that there was a small red paint table inside, Cao Yi thought of someone: "Is this something that was prepared for Lu Sheng?"

Zhang Han nodded: "No, but it's not available now."

Cao Yi walked to the edge of the soft couch, took off his shoes, went up, and knelt down. I don’t know when, but Cao Yi was used to kneeling down.

When Zhang Han also took off his boots and sat down on his knees.

Cao Yi opened up the conversation: "The first thing to do when going to sea is freshwater. Danshui is the water you usually drink. It is very difficult to find freshwater in the vast ocean. Even if it is found, it is not easy to store. So before departure, the general needs to fill each ship with wine. The wine is resistant to drinking and not easy to break. When it rains, he can also use a jar of wine to collect water."

"Wouldn't you have to drink every day?"

Zhang Han, who was full of creeds of marching people not drinking, reacted a little loudly 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, so he nodded and said, "Han, please keep the words of Mr. In mind."

Cao Yi said the second thing again: "The sea is vast and the direction is difficult to tell. If you are not careful, you may be lost in the endless sea. I have a compass here, and the general will carry it with you."

After saying that, I took out a compass from the gourd and bought when I left the Dragon Search World.

Zhang Han took it into his hand, looked at it for a while, and showed an inexplicable expression.

Cao Yi pointed to the letter above and said, "This represents the south and this represents the north. If you can't remember, you can use a dagger to carve the small seal script now."

Upon hearing this, Zhang Han pulled out a dagger from his waist and carved it.

Cao Yi looked at the busy Zhang Han and remembered an object similar to the compass, Si Nan. It is said that it was invented by Zhao State in the Warring States Period.

The first time I mentioned Si Nan was "Guiguzi·The Tenth Chapter", and the article said: Therefore, when the people of Zheng took jade, they carried Si Nan's carriage, so that they were not confused.

Traditionally, Sinan is believed to be in the shape of a spoon.

In the 1950s, an academician named Qian was entrusted to try to make a spoon-shaped Sinan with natural magnets, but because the natural magnets are small and the bottom friction is large, it is unsuccessful. Later, Mr. Wang Zhenduo used tungsten steel as a restoration to magnetize in an artificial electromagnetic field.

Many scholars questioned that Sinan is not in the shape of a spoon, and the National History Museum no longer displays Sinan's model.

"Carried"

Zhang Han put down his dagger.

Cao Yi said the third thing: "People who don't eat vegetables for a long time will get sick. My advice is to carry more soybeans and mung beans, that is, soybeans and beans, and soak some every once in a while."

This time, Zhang Han nodded without thinking: "No"

Cao Yi thought about it and found that there was nothing else. From the soft collapse, he said: "Just come here, General, go back and rest."

Zhang Han got off the soft collapse, put on his boots, said goodbye and left. As soon as he walked outside, he heard Cao Yi's voice again: "Come again tomorrow morning, I have something to send to the general."

Zhang Han responded and left.

In the military tent, Cao Yi has a few more talismans in his hand. He has been busy recently and has not drawn talismans, so he has not stored many talismans.

"I originally planned to choose a few disciples, let's talk about it tomorrow."

After Cao Yi finished speaking, he returned to the soft collapse, took out the corresponding talisman drawing tool and placed it on the table, and started drawing talismans.

The disease treatment talisman, the corpse-suppressing talisman, the spiritual talisman, the character and the thunder talisman are all drawn, but the disease treatment talisman is mainly used.

Because of enough drawings, the speed is much faster than before.

When the painting reached the middle of the night, Cao Yi's face suddenly changed, and there was not much spiritual energy stored in his body.

Pour out the jade from the purple gold and red gourd, and the result is basically all used.

After thinking for a while, Cao Yi suddenly thought of something - Tianxing.

Yesterday, I only used half of the formation of the immortality formation on Mount Tai, and there were still half.

As soon as my thoughts moved, a piece of royal blue emitted a dazzling light. The thrillingly beautiful stone floated out of the gourd with a clear air.

Cao Yi put his hand on it and ran the "Golden Liquid Return to the Alchemy Method". I don't know if Tianxing has a self-protection function, which is much slower than absorbing the spiritual energy in jade. After sucking for an hour, he didn't absorb much. However, the advantage is that it is large in quantity, and you can slowly absorb it.

At some point, it was dawn. Cao Yi, who had been practicing in the middle of the night, walked out of the military tent and saw the sun rising from the horizon. Tens of thousands of rays of light shining on the vast wilderness, paving a layer of golden light to the earth.

"Tao Master"

Zhang Han came, holding a few scrolls in his hand.

Cao Yi glanced at him and asked, "What is the general holding?"

Zhang Han said: "Your Majesty gave you a map and several portraits of god-given things. Your Majesty asked Han to bring it to the Taoist Priest for a look."

Cao Yi brought Zhang Han to the military tent and looked at it one by one. The map was a map of the Pacific Ocean, which was much more detailed than yesterday. The gods were given, or potatoes, sweet potatoes, and corn, and the drawings were also very similar.

This first emperor in Chinese history has good painting skills.

After reading it, Cao Yi told me: "It doesn't matter if the corn is brought back. You must bring back the potatoes and sweet potatoes."

Compared with corn, potatoes and sweet potatoes that consume too much land fertility and produce no big advantage in yield are more important.

Zhang Han shook his head firmly: "Since Your Majesty has the order, Han will bring all three kinds of gifts from heaven."

Cao Yi didn't say anything more when he heard this.

He picked up a wooden box containing a hundred talismans on the table and said, "It is inevitable to encounter poisonous substances on the road. The talisman inside can save your lives at critical moments."

Zhang Han knew Cao Yi's power and respectfully took it: "Thank you for the generous gift of Taoist priest."

"Go"

Cao Yi waved his hand.

Zhang Han left with a wooden box and a few scrolls.

In the following time, Cao Yi did morning classes and read scriptures.

When the Sun Mountain was three o'clock, the soldiers brought breakfast. When Cao Yi was halfway through eating, he heard a noisy sound outside, put down his chopsticks and walked out.

In sight, a slightly fat alchemist was beaten by a group of alchemists.

Cao Yi was about to go over, when a thin alchemist rushed over and knocked down two alchemists, but was soon overturned by the alchemists.

"stop"

Cao Yi shouted.

"One other nosy"

"Call it"

...

The alchemists rushed towards their savior.

Cao Yi was like shooting flies, knocking dozens of alchemists to the ground effortlessly.
