Sleeping on the dead grass felt uncomfortable at all, and the extremely tired Bufan was not honest when he slept, and when he stretched out his arms and legs in his sleep, he inadvertently smashed into the stone wall......

"Ouch,!" the sharp pain in his fist woke Bufan up.

Holding his fists, he sat for a long time before he realized that he was sleeping in a grotto in a strange alien planet, not on a soft and moderate mattress.

He got up from the haystack, stretched, the joints on his body clicked, he didn't know how long he had been asleep, all the astronomical parameters of this damn world were different from the earth, but it was certain that it was much longer than twenty-four hours, otherwise he had been busy for so long, why didn't he see it?

The long pickaxe picked open the bushes at the entrance, and Bufan muttered to himself as he walked out.

"Huh, how long is a day in this damn world?" Bufan, who felt like he had slept enough, stared blankly at the sky outside.

The sky outside was not pink as he imagined, but blue-purple before he slept, and the three bright moons hung in the sky at different angles...... That's the planet's moons, and there are so many of them!

What kind of world is this?

There are two stars, there are at least three moons, and the creatures on the ground have a lot of legs, while the intelligent creatures have only two legs, but they have two more arms...... Could it be that the creator of this world likes to have more of everything than others? Well, last night's wolf leg was good, with a few more legs, and it was enjoyable to eat, so I don't know that there is no chicken with four legs......

Bufan was thinking about it in his heart, and his hands were constantly busy.

Even if there are ten satellites in this world, it is none of his business, the top priority is that he must prepare self-defense equipment as soon as possible, and then hunt to fill his stomach, and set up a safe enough place to live, everything must be done with both hands, before he really had no energy, now that he is resting, how can he waste time?

This unknown alien tribe really has some collections, but unfortunately, there are only a few that are really suitable for him to use - different heights and different body structures will of course be different weapons.

Before going to bed, he turned out a lot of them, but there were few that could be used directly, and most of them needed to be carefully transformed.

And before the renovation is completed, no matter what, go in search of food?

That's definitely irrational behavior.

A pickaxe can handle at most for a while, but what if it falls?

Hand-to-hand combat? No, that's death-seeking!

Wild animals are not domestic pets, their claws and teeth are not ornaments for humans to hang on their bodies, but weapons for food!

A fierce beast with fangs and sharp teeth fighting with bare hands? Once or twice is a warrior, three or four times is a reckless man!

Bufan is certainly not a reckless man.

In addition to the few things that are used, there are also some things that can be used after a transformation, and this is what Bufan is busy with at this time.

A mace with a length of nearly two meters was rested on Bufan's lap and kept resting, this thing weighed at least forty catties, and it was the same material as the spearhead found before, and it had not decayed after many years, but most of the tooth thorns on it were broken.

Bufan didn't have tools like an anvil at hand, but that didn't stop him from repairing it. He also had real wolf teeth knocked out of the six-legged wolf's mouth by his side, which was fitting in the groove of the mace.

Well, the reason why he chose this is because he has never played with a long cold weapon, and he had to fight with a long pickaxe before, and it is unrealistic to expect to become a cold weapon master all of a sudden, but there is nothing wrong with wielding a powerful mace.

As for the spearhead, Bufan didn't plan to give up, he was going to have a spear shaft as a spare weapon.

The weapon has been replaced, the armor must also be updated, the metal shin armor can not be taken and used directly, there is no animal skin as a backing for fear that there is no defense, he will cut his legs, for the time being, he can only use the scale bark as the backing, the metal shin armor is tied to the outside, the arm defense is also the same treatment, the torso is more troublesome, in desperation, he can only remove a few metal plates, the front chest and back are tied to such a piece, the effect, it is estimated that it can prevent one or two scratches of the beast, and then it will definitely loosen.

But there is no way, this is already what he can do right now, if he encounters an enemy who can't be stopped...... Then you can only rely on your own ruthlessness.

To be fair, he would have liked to have a well-stocked rifle or submachine gun, even a crossbow, but that would only require the tools and materials at hand, and the ability to make it.

The mace with real wolf teeth is on his shoulder, the spearhead is stuck obliquely behind his waist, and there are three or five daggers of all sizes pinned to his body.

Of course, the premise is not to exceed the strength or power of his individual combat power.

......

Choosing prey, trying to hunt, and feeding one's belly are all sorts of things, and it goes without saying that setting up camps, driving away foreign enemies, and creating a place to rest and sleep - with a secure grotto with four walls, there is only one way to defend in one direction, which is really not a problem for a doctor who has been trained in survival.

The rocky belt is not rich in species, and it is difficult to form a complex food chain, and of course there is no food for large animals, so there are no huge species to stay here, but it is enough for Bufan alone, although his appetite is also growing.

The stream where the meltwater of the snow-capped mountains gathers is very cold, but there are fish suitable for cold water survival, these fish are also fusiform in shape, and they are not called weird, and they are boiled in a cleaned alien pot with a little rock salt, which is really a rare delicacy for a foodie who has eaten the periodic table in another world.

In the following time, except for occasionally going out to hunt some small animals and coming back to make tooth sacrifices, Bufan lived a busy and leisurely life.

Busy is to better understand the world, leisurely because there are no external factors to disturb, he can do whatever he wants.

Most of the time, survival is as simple as that.

Enough food to eat, water to drink, a safe place to rest, and enough weapons to defend yourself are all enough for a less demanding person.

Everything else is nothing but an add-on to the fulfillment of the conditions for survival, such as the reproduction of species, material enjoyment, spiritual entertainment...... Wait a minute.

Bufan was certainly not an ascetic masochist, and he had to survive, at least for a short time, before his scholarly soul began to stir.

The world itself was his first and most important concern.

Although he is not an astrophysicist, how can a world completely different from the earth suppress his desire to explore from time to time?

Up to the double stars in the sky during the day, the moons that feel like topaz at night because of the illusion of color, down to the grass, trees, bricks, and stones that exist on the ground, and the ...... that swim in the water, fly in the sky, and run on the ground Everything is what he has his eye on.

For example, the alien former residence where I live seems primitive, but is it really primitive?

The boulder where the cave is located is very hard, it is the wind erosion and water immersion for many years, but it has changed slightly, what tools did those four-armed aliens use to dig out the grotto?

You must know that there are no traces of an axe on the stone walls of the cave, and there are many small stones with a very regular shape on the outside of the mountain-sized boulders, which are very similar to the shape of the cave - as a doctor of engineering and mechanics, this technique of digging in the rock without damage is simply fascinating to him.

The petroglyphs in the caves are a good source of information, and although the text is incomprehensible, the graphics themselves are the best medium for disseminating information, and it is a good pastime to interpret them when you are bored.

In addition to this, the metal weapon he now wields is also a mystery.

Immortal and stainless for many years, hard and tough, these materials are obviously not naturally formed, so the question is, if the aliens are just a slash-and-burn ignorant group, how do they refine these materials and process these weapons?

You know, aside from the shape of the weapons, the materials of these weapons themselves may be the key to solving certain industrial problems!

New materials, new processes, nothing compares to the appeal of these to a doctor of mechanics!

After looking at the astronomy and alien geography of the four planetary cycles, Bhufan immersed himself in this "primitive" ruin, and spent his days either digging into caves with torches or hammering around huge rocks with a pickaxe.

The stretch of rocky belt covers an area of more than 10 square kilometers, and there are tens of thousands of caves excavated among the boulders, and it is not easy to complete the exploration of them alone.

But for Bufan, this kind of adventure, curiosity, and search that may cover the scope of his own discipline is not too pleasant! New knowledge is the greatest treasure compared to the so-called gold and silver treasures! Even the journey of exploring them is a happy thing!

Just like his repeated quests and arguments in the library of the University of Prussia, just like his repeated attempts to surpass himself in various unfamiliar environments, it is never easy to obtain.

There are no shortcuts on the way to knowledge, every time he knocks on the rock wall, every time he explores the cave, every time he summarizes the gains and losses, he feels that he is one step closer to finding the answer.

Maybe it's really the emperor who pays off, or maybe it's a will, and after the seventeenth planetary cycle, Boufan finally discovered something very interesting.
