In the blink of an eye, Zhang Shuo had been in the Wu people's camp for nearly half a month.

Half a month has passed, and only a dozen or so wounded soldiers are still recuperating in the wounded barracks, and the rest of the wounded soldiers, except for two sudden emergencies, have all recovered and left.

In the past half a month, Zhang Shuo has taught Xiao He some knowledge that can be taught orally, which is not only battlefield medicine, but also some knowledge of biology, pharmacology and microbiology that Zhang Shuo has mastered.

In the past half a month, Wu San has come several times and told Zhang Shuo some of the current situation in the outside world, those displaced people who broke through Nanyang County have no intention of crossing the river, they don't seem to look down on the wild land of Nanling, but are marching towards the east of Jiaozhou, and there is a tendency to sweep the southeast.

The war outside did not have any impact on Huangxi Village, but the potatoes and sweet potatoes left by Zhang Shuo were ripe, and every household had a bumper harvest, and Wu San also brought Zhang Shuo the gratitude of the whole village for this.

Now, the xenomorph spiritual power on Red Sleeve's body has been dispelled clean by Zhang Shuo, and after Zhang Shuo's spiritual power infusion, Red Sleeve's cultivation has improved a lot, and his state has never been better.

Red Sleeves' injuries were healed, and the wounded soldiers in the wounded barracks were basically healed, so Zhang Shuo decided that it was time to leave here.

When Zhang Shuo used to cultivate, he could only practice for four or five hours a day, and if he practiced for a while, he would be dizzy, and at that time he thought that cultivation would consume energy, but now after the red sleeves explained, he realized that this was not the case.

In ancient times, the aura was full, and after the monk broke the spiritual aura, absorbing the aura from heaven and earth was as simple as eating and drinking, but now the aura is scarce, and then cultivating like in ancient times, it is natural to consume more energy to absorb the aura of heaven and earth, so Zhang Shuo will have dizziness and brain swelling.

Today's cultivation method has a more refined control of spiritual power, especially after breaking the spiritual aperture, although the spiritual energy absorbed is less than Zhang Shuo's, but it is better than continuous, the water flows for a long time, and you can practice day and night!

After some monks break the spiritual aperture, they can nourish their bodies with endless spiritual power to achieve the effect of Bigu, so they can often retreat for several years without eating or drinking, but Zhang Shuo can't do this step, because Zhang Shuo is extremely consuming when he is practicing, and he can't do this step at all!

Therefore, after the affairs of Nanyang County were basically over, Zhang Shuo planned to go to the Sword Pavilion with Red Sleeves, and then find a suitable exercise to transfer.

In the wounded barracks, Zhang Shuo was conducting the last examination, and he had to leave some medicine for these wounded soldiers, otherwise they would be in trouble if they had wound infections after he left.

"Is Mr. leaving?" After Xiao He came to the wounded barracks, the first thing he said was to ask about the news of Zhang Shuo's departure.

"Yes, I'm leaving tomorrow. Zhang Shuo nodded, he had already informed Situ Weiming of the news that he was leaving early in the morning, and Xiao He was not surprised to know that Zhang Shuo was not surprised.

Xiao He heard Zhang Shuo's answer, lowered his head slightly, and asked in a low voice, "Will Mr. come back?"

"This ......" Xiao He's words made Zhang Shuo stunned, he thought about it carefully, will he come back after leaving here?

Suddenly, Zhang Shuo seemed to have figured out something, he grinned, and said to Xiao He, "Of course I will come back, if I am tired of walking, I will come back." ”

"Really?" Xiao He raised his head, his eyes narrowed into two crescents, and then he took out a red bead from his arms, and said with a smile, "Mr. gave the grace of the industry, Xiao He can't repay it, this is a pendant made by Xiao He himself, I hope Mr. will accept it." ”

Zhang Shuo looked at the pendant handed over by Xiao He, it was a blood-red jade bead the size of an eyeball, a hole was punched in the middle of the jade bead, and it was strung with a black thread that could not be seen in the material, although it was very simple, but the workmanship was very exquisite.

"You have a heart. Zhang Shuo smiled and took the pendant, and naturally put it on his neck, Zhang Shuo liked this nine-year-old girl very much, smart, well-behaved, and very sensible, I believe that every teacher would like to have such a student.

"That's right, Xiao He. After Zhang Shuo put on the pendant, he saw Xiao He standing there in a daze, so he said, "I happen to be free today, what I have taught you these days, if there is anything you don't understand, you can tell me, and I will try my best to answer for you." ”

"Don't you understand?" Xiao He tilted his head, with a thoughtful look on his face, and then said slowly, "Last time, Mr. said that mushrooms are made up of invisible insects, can you elaborate on them?"

When Zhang Shuo taught Xiao He about microorganisms, because there was no microscope, no teaching methods such as pictures and videos, Zhang Shuo described microorganisms as a kind of small insects that were invisible to the naked eye.

"Okay, I'm going to tell you about these invisible little bugs today......"

Zhang Shuo did not talk about the cell structure of fungi in detail, because there was no way for Xiao He to observe it with his own eyes, even if he did, it was useless, Zhang Shuo first started with the growth and reproduction of fungi, and then talked in detail about the classification of fungi and so on.

In the end, Zhang Shuo even extended from hyphae and spores to interesting topics such as fungus blankets, broods, incubators, and the Zerg Empress in interstellar games, of course, Zhang Shuo talked about everything in the game as anecdotes, but Xiao He listened very carefully.

Time passed quickly, the two of them spoke seriously, the other listened carefully, and it was dusk in the blink of an eye, Zhang Shuo finished talking about the last bit of dry goods in his stomach, and finally separated from Xiao He with a look of uncertainty and returned to his bamboo building.

On the other hand, after Xiao He left the wounded barracks, he first chatted with the elder as usual, and then hurriedly returned to his bamboo building.

Xiao He's bamboo building is different from ordinary bamboo buildings, the ground floor of ordinary bamboo buildings is empty, and usually people don't live there, but five or six clay pots are placed on the bottom floor of Xiao He's bamboo building, and each clay pot is tightly covered.

Xiao He opened the lid of a clay pot with ease, and in an instant, a centipede more than half a meter long poked its head out of the jar, this centipede was about the same size as an ordinary grass snake, a pair of serrated teeth kept opening and closing, hideous and terrifying.

Xiao He saw this centipede, not only was she not afraid, but her face was happy, she stretched out her finger and touched the centipede's head lightly, and the centipede actually retracted into the jar very docilely, and there was no longer a fierce atmosphere!

Xiao He pricked his index finger with copper, and a drop of bright red blood dripped from his finger into the clay pot, and the blood dripped onto the centipede's body, melting into the centipede's body at a speed visible to the naked eye, the centipede trembled, and then the whole body coiled into a ball, as if falling into a deep sleep, and no longer moved.

In this way, Xiao He opened one clay pot after another, and dripped blood into each clay pot in turn, and there were toads, snakes and some strange insects in the clay pot, but when it came to the last jar, it turned out to be a mushroom!

"Since Mr. said that you are a worm, then you should also be able to become my Gu......" Xiao He looked at the mushrooms in the clay pot, gently dripped a drop of blood, and then closed the lid and left here with brisk steps.
