I was a village chief in a primitive society

After Su Bai finished breakfast, he continued busy with his own affairs. The four great inventions were also fully presented in the Yanlong tribe.

The first was papermaking, then gunpowder, and finally printing and the compass.

The compass is not difficult to make. The main material is magnet.

The principle is to install a magnetic needle on a shaft. The magnetic needle can rotate freely under the action of the natural geomagnetic field and remain in the tangent direction of the magnetic meridian.

The north pole of the magnetic needle points to the north magnetic pole, and this property is mainly used to identify the direction.

The emergence of magnet orienting devices has enabled people to shift from the passive orientation of observing celestial bodies to the active orientation of geomagnetic orientation.

On the other side of the earth, compasses are often used in navigation, geodesy, travel and military affairs.

Su Bai wanted the warriors and other members of the tribe to better identify the direction of the tribe when they went out.

After all, sometimes people's intuition can be wrong, and the tracks in the forest can be easily destroyed.

Especially during the rainy season, if you go out somewhere along the original route, but it keeps raining, the marks you made before are destroyed.

Or maybe the surrounding environment has changed, and it is difficult to identify the direction of the tribe at this time.

"Wu, what is this? Yuying asked curiously

"I'm doing gene conversion."Su Bai looked at the bottles and jars on the table with satisfaction.

"Wu, what is gene conversion? And why do we need to use so many seeds?"Yu Ying shook her pink fox tail.

There were many kinds of seeds on the table, including wheat seeds, rice seeds, various fruit seeds, etc.

"For example, is this sour fruit a bit sour?"Su Bai took the lead in picking up a sour fruit.

"Yes, it’s sour that makes you frown after eating it."Yu Ying nodded without hesitation.

She even showed a bit of disgust. For no other reason, this sour fruit is so sour that she can't eat it.

Of course, this is just for her, and there are many people. Like to eat very sour food

"Isn’t this orange a little sweet? And it's a little too sweet."Su Bai picked up the orange from the table.

This orange was produced from the seeds he planted in the system, cultivated and grown.

It may be due to the geographical environment, plus the problem of the seeds provided by the system.

The system gave them The oranges grown from the seeds are extremely sweet, so sweet that it chokes the throat.

Su Bai doesn't like this very much, because after eating one or two pieces, he can't stand the sweetness, especially It makes the throat greasy.

But for other people in the tribe, it doesn't matter. They rarely eat such sweet fruits.

In addition, they bite the fruit with the skin, and the spicy taste of the orange peel neutralizes the sweetness. They Still very accepting

"Yes, this orange is a bit sweet and can only be canned."Yu Ying still nodded.

Fox-eared lady still liked eating oranges at first, but after the production increased, the quantity also increased.

Sometimes she would feel tired after eating too much, mainly because the sugar content was too high..

Under the leadership of Su Bai, the tribe began to launch canned foods, which contained a variety of pickled foods.

Not only meat, but also some vegetables were also pickled in the jars, and finally some canned fruits.

"So if we combine the two, will the oranges produced not be cloyingly sweet?"Su Bai smiled.

He wanted to explain it step by step so that the other party could understand it faster.

"So, this is indeed a good idea, but it shouldn’t be possible, right?"

Of course Yuying thinks it's good to combine the flavors of the two fruits, but it's a bit difficult to implement.

"Little fool, forget it, I am good at witchcraft."The corner of Su Bai's mouth rose slightly.

He had already developed a talent skill some time ago, which is the extraction and conversion technique.

However, because he was busy with many things, he did not implement this talent skill specifically.

It just happened that there were not many in the past two days. In addition, the rainy season has arrived, so I can put my work aside for the time being.

The main reason is that I saw the oranges on the table during breakfast, and then I thought of using this talent skill.

"Yes, Wu seems to have said that something similar is witchcraft before."

Yu Ying scratched the back of her head in embarrassment and muttered,"The witch guild has so many witchcrafts, I didn't think about it at once."

"Be good, go and do your work first."Su Bai's tone was particularly gentle.

He always spoke very gently to Fox-Eared Lady, mainly because he wanted to make her change her personality quickly.

"If Wu needs anything, he can come to me."Yu Ying nodded happily.

Su Bai moved his fingers, preparing to start the extraction and conversion technique. There were also a lot of seeds on the table.

That means there are still many things to experiment with, not just oranges and sour fruits, but also Even wheat has to find a way.

Su Bai wants to combine wheat with Pennisetum. The ears of Pennisetum are particularly large, much larger than ordinary wheat.

If this advantage of Pennisetum can be converted When it comes to wheat, the wheat will also produce a large bunch of ears.

In addition, the same is true for rice. All three must be tested.

Of course, vegetables and the like are not spared, and some plants are not spared at all. They are not afraid of insects.

Except when there is heavy ice and snow, their leaves are always bright green.

There is no sign of insect damage on them. In the primitive era, there were no insect repellents such as pesticides.

Su Bai could only improve in this aspect. Anyway, there is no need to use the extraction and conversion technique in vain.

He stretched out his hands, placed one hand on the orange, and placed the other hand on the sour fruit, and began to perform the extraction and conversion technique. A series of sapphire blue lights lit up from the palms of his hands, After that, the two fruits separated into a small chain of royal blue light.

The two small chains of royal blue light slowly joined together, as if two ropes were twisted together.

The whole process lasted for a full minute. , it was not until the sapphire blue light slowly dissipated that Su Bai withdrew his hand.

He picked up the sour fruit and the orange and weighed them, and found that they were indeed a little different from their original weights.

"Try it first to see how it tastes, and then you’ll know if it’s successful."Su Bai peeled the orange peel.

He took out a piece and put it into his mouth, chewed it several times and nodded with satisfaction. It was obvious that the experiment was successful.

Su Bai put the sour fruit aside and did not try the sour fruit. The taste.

Because the extraction and conversion technique is to extract the benefits of one thing and convert it into another thing.

Su Bai has already extracted the acidity of sour fruits, but the sweetness of oranges has not been extracted.

So the current sourness If it's still the same as before, there's no need to try..........................................
