"Actually, it's all the help of the old man, the old man has re-improved the light body formula, and made a second modification to the light body formula according to the meridians in these primitive human bodies, and because when the old man transformed, it was based on the prototype of those primitive people with the smallest number of meridians, so no matter what the number of meridians in the body is, these primitive people can cultivate the improved version of the light body formula."

While talking Yan Feishuang, he handed Zhou Ran a tube of bamboo slips, the thickness of this bamboo slip was much thicker than the blank bamboo slips that Zhou Ran used to record his content, and then Yan Feishuang turned around and pointed not far from the open space, where there was a wooden box, which was one of the containers Zhou Ran made in his spare time during this time, and there were twenty or thirty bamboo slips piled up in it.

"This is the old gentleman's improved light-weight technique, all of which are just the content of a total of exercises," Yan Feishuang also showed a somewhat helpless look on his face when he said this.

She is also from the Beacon Era, although the level of the Beacon Age is basically not comparable to modern times, but at least one thing is still good, that is, there is quite a practical straw paper.

At least there is no big problem in recording some of the content, and it is definitely more convenient than these bamboo slips, knowing that the book that recorded the light body recipe before was only half a centimeter thick, and now the light body recipe improved by the old man actually took twenty or thirty bamboo slips to record.

The most important thing is that after pointing out the direction to Zhou Ran just now, Yan Feishuang also subconsciously added a sentence, saying that it was the old man's improved exercises, and the content was about half less than the original.

Feeling the need to put the issue of straw paper on the agenda, Zhou Ran scratched his head helplessly, and then he took the bucket of bamboo slips in his hand and walked to the side of the wooden box, as an item, if you only get a part of it, there is no way to see the detailed information.

[Light Body Trick Change: Waste-level Exercises. The innate martial artist used his rich martial arts experience to forcibly transform this set of basic exercises suitable for ordinary people in the Beacon Fire Era into a light body exercise that could be practiced by the primitive people of the primitive era. Practicing this technique can greatly reduce one's own weight and increase the weight during long-distance travel, run faster, and consume less stamina, but it is only suitable for long-distance travel, and there is no obvious advantage in tossing and turning in close combat. 】

Zhou Ran put down the bucket of bamboo slips in his hand, nodded slowly, in short, it was the same as he thought, to put it bluntly, he retained the original ability of the light body technique, and then changed it from a person who was suitable for the Beacon Era to a primitive person who was suitable for the Primordial Era, and there was no other effect other than that.

Although it seems to be very ordinary, in fact, this ability can be called very strong, for example, Zhou Ran, if the current Zhou Ran only calculates the total amount of internal qi, it can be regarded as reaching the innate level, but if he is asked to modify it, he really can't do it.

If he was asked to modify the basic exercises of cultivation, he might be able to give it a try, after all, when he was practicing the Qi Era, he spent more energy on his own cultivation, and in the Beacon Fire Era, he was so focused on only studying his own tattered and mixed Yuan Gong, resulting in no advantage or advantage at all in this regard.

The only place where he can show is that the speed at which he masters this technique is not slower than a few generals in other camps, as for really letting him modify it, he can't do it, he nodded with some admiration, and Zhou Ran felt more and more that it was really fortunate to be able to recruit the old man through the bonfire.

The mere fact of modifying the exercises alone could prove the value of the old man, not to mention that he could refine so many kinds of pills, and even be able to teach people other kinds of martial arts.

Although it is said that teaching martial arts, this kind of ability is not used by ordinary people, but this thing is useful for geniuses, and it just so happens that in Zhou Ran's territory, even Zhou Ran himself or even fierce, can barely be called a genius.

Patting the huge wooden box, Zhou Ran turned his head and nodded at Yan Feishuang, and then said softly: "In short, the task of teaching the exercise of light body decision will be handed over to you, you must get it done, if these wild stone spearmen can all practice this light body exercise, then when they go out for hunting and long-distance running, it will be a big problem." ”

If they can really cultivate the successful light-weight exercises, then the research of the chariot is not so anxious, in addition to the main ability of the chariot is to charge and cause a very strong sense of momentum and oppression to the enemy, the rest of the main function is to stay on the cargo, and the chariot that pulls the cargo and the chariot responsible for the charge must be different in small details.

It is definitely impossible for the two to be combined, so Zhou Ran can only focus on researching one of them first, and he used to focus on these research vehicles, but now it seems that he can focus on the trucks carrying goods first.

Thinking of this, Zhou Ran felt more and more relaxed, but he didn't expect to just come out and take a turn, and he solved another problem, when he passed by the bonfire, he picked up a large piece of barbecue meat from the surroundings, and then took a bucket of water, Zhou Ran did not stop on the road, and solved the problem of his lunch while walking, and when he just arrived at the river, he saw at a glance the small bamboo shed that was still piled up by the river.

This small bamboo shed is a small bamboo shed built around the earthen stove after Zhou Ran got the earthen stove some time ago, after all, there is no problem with this earthen stove whether it is dried in the sun or shade, as long as it is guaranteed that all the moisture in it is lost, and the entire earthen stove is kept transparent inside and outside.

But if there is no moisture prevention measures and the rain is caused, the whole earthen stove is basically scrapped in an instant, so he built such a small bamboo shed to shelter from the rain, and now it seems that the effect is still good, after all, it just rained two days ago.

Walked into the bamboo shed, Zhou Ran squatted next to the earthen stove, began to study left and right, after about 4 days of air drying, this earthen stove can basically be regarded as internal and external, put his hand into the inside of the earthen stove, can only feel some cool air and a slight breeze, there is no feeling of moisture.

Zhou Ran's perception ability was already very strong at this time, and after he attached a thin layer of flame internal qi to his hand, this perception of moisture was particularly strong, as if he could feel it now, the breeze blowing on his cheeks mixed with the moisture coming from the water surface by the river.

But there is no such moisture in the earthen furnace, which also makes Zhou Ran breathe a sigh of relief, at least ensure that the first step of the earthen furnace, there is no problem with air drying, in this case, then you can try the next steps, as long as you ensure that this earth furnace has no problem with the heat resistance of the foundation, you can start to officially smelt metal.
