If you are lucky, you can find some other characters with medical skills, or even teach medical skills, then the old man's pharmaceutical skills will definitely be able to improve.

As for other good things, there are not a few, the clay medicine furnace is indeed only the lowest level, and it can't even be called the existence of the medicine furnace, but with it, it is indeed alchemy that has become a possibility.

Zhou Ran was holding a large number of small bamboo tubes and porcelain bottles in his arms, which were full of various types of medicines that the old man had given him, most of which were related to healing or rejuvenation.

After all, many medicinal materials are not complete now, and he can only try drugs with similar properties, more than a dozen prescriptions, and in the end only three or four of them succeeded, but the effects of these three or four kinds of drugs are not bad.

"Okay, that's pretty much it, you take them all back, remember to take one every other cycle, after eating, you have to do a lot of training, if you eat all the bottles, your physique should be able to rise again by about 5 points, you must remember to eat it as soon as possible, the medicinal power of this pill is not very strong, and when your physique exceeds 30 points, I'm afraid it will have no effect."

"As for the spirit snake blood, I still have to study it for a while, old man, the effect in this spirit snake blood is very strong, I am afraid that if the matching medicinal materials are not very matched, the effect of the pill produced may not be as good as imagined, and I don't know when I will have to wait until the next time I want to encounter such a high-grade material."

While talking, the old man stretched out his hand with some discouragement, and smashed the clay medicine stove on the side, of course, he didn't really use force, but it looked very scary: "And you kid, hurry up and find a way to bring the old man a similar medicine stove for me, it is a medicine furnace made of soil, you see the old man, I have only practiced more than a dozen times, and there are already cracks on it!" ”

Zhou Ran showed a look of surprise, he went around and went around to the back of the clay medicine furnace, and saw a few cracks on it at a glance, he squatted down and took a closer look, and found that this should be the old man's long-term use, injecting too much flame attribute internal qi into it, and being scorched by the temperature of the flame too many times, which led to such a situation in the clay medicine furnace.

So Zhou Ran really has nothing to say, because in the final analysis, the clay medicine furnace he made is too unbuilt, and it is clear that it is his problem, so in desperation, Zhou Ran had to nod and promise to bring a new and better medicine furnace to the old man.

To be honest, he also intends to do this, this time after coming back for a long time, he does not plan to go out again, at least in a cycle or two, he will nest in his territory to open treasure chests, and by the way, make some carpentry things.

Now there are a lot of materials accumulated on hand, and as for the task of hunting primitive tribes, it is enough to hand it over to the other three generals, they only need to take turns to go out once, and one or two will go out.

After all, the frequency of refreshes has dropped very much recently, even if you only go out one or two and take those wild stone spearmen around a few times, you can also empty all the primordial tribes that have been refreshed around, and if you want to refresh them again, you may have to wait for another cycle or two.

Zhou Ran didn't want to waste all his time wandering around in the wilderness, he had to take advantage of this time to strengthen the combat effectiveness in the territory more, and not only these things, he also had to put the issue of training cavalry on his daily basis.

The bighorn birds have produced a lot of numbers in the animal pen recently, but they are all walking around in the animal pen every day, eating insects or grass on the ground, and then running wildly with other little companions in the animal pen, life is very carefree, and Zhou Ran, who is standing outside the animal pen, feels very worried.

The strength of these bighorns is just too great. Some time ago, after he saw that these bighorn birds had almost trained a lot of numbers, he asked the two wild stone spearmen to try to ride into a bighorn bird to feel if they could quickly comprehend riding skills and other abilities.

However, the result was very tragic, although the bighorn bird could not be called unruly, but it did not like to have other creatures riding on its body, only to see it directly come and throw one of the primitive people away.

And the second one rode up was even worse, the bighorn bird jumped up directly like a wild horse, landed on the ground with his back, and broke both legs of the primitive man, he is still lying on the bed to recuperate, if it weren't for the new old man in the territory, an expert who has mastered pharmaceutical technology, and even has the internal qi that can heal injuries with medical properties, then the primitive man may not be able to fight anymore.

It is precisely because of such a thing that the domestication of the bighorn bird has come to an end temporarily. Zhou Ran has been worrying about how to train the bighorn bird into a mount for a while.

But after having the previous hand-cart incident, he realized that it was not necessary to train the Bighorn Bird as a mount, and it was also a good choice to train them to carry goods or pull carts.

In ancient history, there was actually such a thing as a chariot, which was probably a small car made of wood and metal, with two or four wheels underneath, usually four wheels, and a metal fence on top of the car.

And then there are up and down positions, and in the back of this small cart can stand a few warriors with spears in their hands, or warriors with bows and arrows, and in front of them there are some creatures like horses that are responsible for pulling the cart, which was called a chariot in the old days.

Zhou Ran now just wants to research a similar chariot or something, this kind of chariot not only moves very fast at critical times, has very high mobility, but also can bring great pressure to the enemy when running.

The most important thing is that if it is not used for fighting, it can also be used to carry goods and the like, a large board car can also carry at least 2~4 tons, and there is no problem with pulling two or three giant saber-toothed tigers.

Of course, it is not so simple to make such a small chariot, or an ancient version of the tank, Zhou Ran is just an idea now, he first went to the animal pen to look at these bighorn birds, made sure that they were in good health, and then pulled one out of it.

The chariot would definitely not be able to be solved for a while, and he wanted to try it first, if it was not used as a mount, but only to carry loads, if it could be successful.
