In the eyes of the monsters, people are the most delicious food, and they can even help them practice, and the tragedy of monsters eating people is endless, and sometimes even the whole village will be harmed by the monsters.

The soldiers of the Great Li Dynasty can't defeat the monsters at all, if it weren't for the fact that the gods needed the monsters' skin and bones to practice the elixir and took the initiative to kill the monsters, the monster clan would be even more powerful for the world.

This time he entered the Fengshen Mountain, Guo Dalu was most worried about encountering monsters, last time a giant python that had not yet cultivated to human form had already made him anxious, and if he had to meet some powerful monsters, he would burp directly - although Guo Dalu ate Guben Pei Yuan Dan, he was only larger than ordinary manpower and responsive, but he was not at the same level as monsters at all.

Brother Hao told Guo Dalu that the immortals are cultivating the mind and cultivating the inner nature, although they have the ability to move mountains and seas, but their own flesh is not very strong, and they rely on all kinds of spells and magic weapons to cast spells, but the monsters are cultivating the body of the deity, and they can directly call the wind and rain if they fight with their hands, and some immortals are not as good as monsters.

And the monster's reproductive ability is extremely strong, and even will catch mortal women to copulate, giving birth to half-human and half-demon, while the immortals are pure-hearted and have few desires, although there are male and female immortals who cultivate both, but it does not involve physical intercourse, and there are even fewer children who give birth. Although the gods have killed many monsters, the monster clan is still thriving, making waves in the mortal world and harming all living beings.

Guo Dalu attaches great importance to his own life, and he entered the mountain this time to find ores, and he is not here to upgrade and fight monsters, so let Hao Ge'er give full play to his ability to sense monsters, as long as Hao Ge'er feels a little wrong, Guo Dalu immediately turned in without hesitation.

Guo Dalu and his party of four people went around in the Fengshen Mountain, in order to worry about getting lost, they left marks on the trunk and stones with colored markers, which would not be washed away even if they were stained with water, plus a compass in Guo Dalu's hand, he was not afraid of getting lost in the jungle.

On this day, it was getting late, Brother Hao found a creek and pressed the camp, the stupid big man collected some hay and weeds, took out a lighter, lit the fire with a snap, pouted his ass and blew, and the fire quickly became hot.

The stupid big man couldn't put it down and looked at the lighter in his hand, this little thing was given to him by Brother Guo, he only used it once and liked it, this lighter is much easier to use than flint or something, and with a slight movement of his fingers, he can make fire. It's just that Brother Guo said that he doesn't have much of this lighter in his hand, and the liquid in it is actually compressed gas, and if the shell is broken, it will run out, so let yourself use it carefully.

The stupid big man heard Guo Dalu say in class that this gas is a colorless and tasteless thing that surrounds people, and what people breathe is "sheep gas", but the stupid big man can't figure out how the gas can turn into a liquid like water.

In the eyes of the stupid big man, Brother Guo is a fairy, no, more powerful than a fairy, because the fairy did not let his family have enough to eat, and since he met Brother Guo, the mother and little sister of the family are happy every day, and the little sister has never woken up in the middle of the night to cry because she is hungry.

At this time, Li Bo hurried over with a few fish and a hare, stripped and washed them, forked them on a branch, and roasted them on the fire, and after a few moments the aroma came out.

Guo Dalu is next to him, he is drawing, of course, it is not a landscape painting, but a map, since entering the Fengshen Mountain, Guo Dalu has been using the simplest ranging method, drawing a map.

Guo Dalu has not seriously learned the surveying and mapping method, measuring the height of the mountain, and can only use the simplest visual triangulation method, the so-called map was drawn messily by him, but this is much better than the map used in the army of the Great Li Dynasty, Brother Hao has seen the map collected at home before, a river is a thick line bends a few bends, the mountain is a few small steamed buns, the city is a square square, not divided into south, south, north, west, let alone any contour line, in fact, the army of the Great Li Dynasty marched, mainly relying on local guides to lead the way, otherwise, the map is also a black eye。

The stupid big brother greeted Guo Dalu and said, "Brother Guo, it's time to eat." ”

Guo Dalu put away the map, sighed, the book to use the time to hate less, he has always been proud of the knowledge of the 21st century, but really want to use it, but found that many of the things he learned are just scratching the surface, such as he knows the contour line, but how to make his own tools to measure the distance, but he is confused, he also knows the general process and raw materials of glass production, but the specific operation is unknown.

The children in the Yixue school didn't know that Guo Dalu returned to his room after giving them classes, but he became the most diligent student in the world, immersed himself in studying all kinds of books that came from the trash can, hoping that he could master more knowledge of the 21st century, but these books passed through the trash can are not systematic, very fragmented, some are still repetitive, and they are mainly based on nursing knowledge - who let Guo Dalu study in the School of Health. Guo Dalu still has too little knowledge about science and engineering.

Guo Dalu put the map and ballpoint pen in a plastic bag, tied it with a rubber band, and used it to prevent moisture, then sat down next to the fire, took a grilled fish handed over by the stupid big brother, and next to Hao Ge'er had boiled water in a small stainless steel basin, poured it into a disposable plastic cup, and wrapped a leaf to prevent scalding, and brought it to Guo Dalu's hand - needless to say, these things were transmitted from the garbage can.

Guo Dalu was just about to speak, when he suddenly asked: "What about Brother Hao? He said that he was exploring the road ahead, why hasn't he come back yet? The sun is about to set, even if he has a telescope in his hand, he can't see far." ”

As he was talking, there was a commotion in the grove next to him, and Brother Hao came out wearing a camouflage suit made of linen, holding a cardboard box telescope in one hand and a plastic bag in the other, which was full of all kinds of plants.

Li Bo hurriedly greeted him: "Brother Hao, you are back, Brother Guo is worried about you, heh, there are so many plants, we haven't seen them before, it turns out that Brother Hao, you are collecting new varieties of plants again." ”

Brother Hao squatted by the stream to wash his hands, and said with a smile: "Yes, didn't Brother Guo tell us that in this sacred mountain, not only the ore is a treasure, but also this plant is a treasure? If we can find any new varieties of plants that can be used to heal injuries and diseases, it will be a great luck." ”

The doctors of the Great Li Dynasty also used herbs to cure diseases, however, Guo Dalu asked around, so far there is no professional medical book such as "Compendium of Materia Medica", and the prescriptions used by doctors are varied, most of them are ancestral, and they are kept secret, and they cure the disease, that is their own medical skills, and if they can't cure the disease, that is, you have reached your lifespan, and you deserve to die.

When it comes to curing diseases, the more reliable one is the immortal palace in the mortal world, and the immortals will have some leftovers from practicing Dan, which are not beneficial to cultivation, but still contain a little aura, and the handymen who leave the palace will collect these scraps, call them divine medicine holy water, and sell them to rich and noble families at a high price. The scraps of these pills are used to treat headaches and brain fever in the mortal world, which is very effective in eliminating diseases under the medicine.

However, such a panacea is not something that poor people like the villagers of Houlong Village can afford, and the poor can't even afford to eat herbs.

Guo Dalu has modern medicines in his hands, but the source of this medicine is extremely unstable, and the medicines from the trash can are extremely messy, so he can't talk about the right medicine, so Guo Dalu found that he could only rely on herbs.

Guo Dalu studied nursing, not traditional Chinese medicine, but he has a lot of feelings for traditional Chinese medicine - you know, Ms. Tu Youyou, who is famous in Huaxia, is from his hometown, Ms. Tu extracted artemisinin to treat malaria with the technique of traditional Chinese medicine, won the dynamite award, and is the person Guo Dalu admires the most, so for a while, he turned over a lot of Chinese medicine classics and memorized soup songs or something.

Traditional Chinese medicine has made rapid progress in the 21st century, and all kinds of prescriptions have been corrected by famous masters in the past dynasties, and they are very curative, not to mention all kinds of Chinese patent medicines, pill powders, although Guo Dalu has only learned a little fur, but it is not many times stronger than those ancestral famous doctors of the Great Li Dynasty.

Traditional Chinese medicine is inseparable from medicinal herbs, after Guo Dalu entered Fengshen Mountain, he not only did it himself, but also told Brother Hao and others to pay attention to the unknown herbs in the mountain wall and stream, if possible, pick a few samples and let him identify them well.

Guo Dalu looked at the bag full of unknown plants sent by Brother Hao, and blamed: "How many of these herbs grow on the cliffs, it is too dangerous for you to pick alone, how many times have I said it, the four of us want to act together and take care of each other, but you don't listen to me." ”

Brother Hao took a roast rabbit leg handed over by the stupid big man, and said with a smile while gnawing: "It's okay, I'm running around in the mountains and forests when I'm a child, picking a few herbs is just a trivial matter, the stupid big man and donkey skin still stay with Brother Guo to take care of you." ”

Guo Dalu snorted: "What do I want them to take care of? I have eaten the elixir, and now I am much more flexible than you." He said as he rummaged through the herbs that Hao Ge'er had picked.

To be honest, Guo Dalu didn't expect to find any useful herbs from this pile of weeds, it was not easy to find ores, and it was also not easy to find herbs, most of the weeds that Hao Geer and others found were worthless weeds, plus Guo Dalu himself was also a three-legged cat, and he couldn't even guess when he identified herbs, so he traveled all the way, and he had been in the mountains for more than half a month, and he didn't find useful herbs in his memory.

It's just that Brother Hao and the others are enthusiastic, and they still pick herbs they don't know when they see them, and Guo Dalu is not good at dampening their enthusiasm, at this time, Guo Dalu is carefully identifying a bunch of weeds, counting on the blind cat to hit the dead mouse--
