At the beginning of August 2161, on the continent of Eden on Proxima Centauri B, Joseph, carrying a large backpack and quiver, and a bow and arrow, headed west-northwest from the eastern part of the Origin Plain and the southwestern part of the Hodkingkaster landform area, aiming for the Guizhou Plateau.

Since the continent of Eden is always facing Proxima Centauri, the star of Proxima Centauri, planet B, the direction of the "sunshine" is basically fixed, and people can easily judge the general direction through the growth of large trees.

It took 10 Earth days for Joseph to cross a large forest on the Plains of Origin, and then saw an endless swamp appear in front of him.

When he was the commander of the advance force, he had reviewed the briefings submitted by the expeditionary force on time, and the expeditionary force had almost slaughtered all the beasts and even the slightly larger herbivores that he had just crossed the forest.

And poisonous snakes, venomous lizards and whatever, no one in the human base has encountered them over the years.

As for poisonous insects, Proxima Centauri B is quite numerous.

According to the regulations, the botanists in the advance army will make specimens of the stems and leaves of plants known on Proxima Centauri B, and indicate their medicinal value, and display them in the botanical hall of the base.

Joseph, while studying the more virulent drugs, also remembered in passing which plant stems and leaves were feared by various insects native to Proxima B.

So whenever he saw plants that were insect resistant, he would pick, dry, grind them into powder, mix them, and apply them to his body and clothes.

This kind of insecticide created by Joseph has a very obvious effect, especially when he is sleeping in the woodland, all kinds of insects within a radius of more than ten meters dare not approach.

Joseph also had a discussion with David about why Proxima Centauri B had not found a venomous snake.

David believes that in the evolutionary history of snakes on the earth, from the appearance of snakes 135 million years ago, it was not until the Miocene of the 3rd Cenozoic Era that venomous snakes appeared in the Miocene, which can be described as extremely long.

The current ecosystem of Proxima Centauri B is very similar to the late Cretaceous period of the Mesozoic Era, although practice has shown that there are many errors, such as the discovery of primates and the absence of large dinosaurs.

However, the idea that Proxima Centauri B's current geological age is similar to that of the Cretaceous period of the Earth is still mainstream among all scientists in the Advance Army.

As for poisonous lizards, on Earth, although there are some poisonous lizards that are contemporaneous with the dinosaurs. Strangely, however, no fanged lizards have ever been found on Proxima Centauri.

This is also the reason why Joseph only worries about being hunted by other humans in the forest, and is not too worried about being attacked by beasts and poisonous snakes.

But this swamp, which is about 300 kilometers wide, is much more than the daily "outing" of people on the base, and scientific research reports show that this swamp is full of predators.

As a result, many well-known and unknown beasts of prey may be waiting somewhere deep in the swamp, waiting for all kinds of prey to enter their sphere of influence.

But Joseph, who knew this, was not so afraid to enter this dangerous swamp.

In ancient times, after being bullied by beasts for millions of years, humans finally learned to use their brains instead of relying solely on strength to deal with beasts.

The ancestor of modern humans--- Homo sapiens, hibernated in the Saharan Desert of Africa more than 100,000 years ago.

About 100,000 years ago, the air in the equatorial region was heated and the Sahara region was freed from the control of the subtropical high pressure zone, and the heavy precipitation turned the Sahara Desert into a grassy savannah.

So Homo sapiens began to march beyond the Sahara and into the world, which in turn led to a reshuffle of the global ecosystem, and in just a few thousand years, many species such as the saber-toothed tiger were eaten up by the relatively "short and weak" Homo sapiens.

In Joseph's view, the uncivilized ancient humans of the old ancestors can kill all the way from Africa to the Americas, Australia and other places, and they are proud of the rivers and lakes.

On this planet where giant beasts have never been discovered, even if you are alone, you can brave the world to the end of the world where you want to go.

But he seems to have overlooked the fact that Homo sapiens dominates the world, relying more on teamwork than on tools.

During a break through the forest, Joseph made a rugged crossbow.

Because there was no condition to make iron, Joseph's crossbow was far worse than the "David's crossbow" in Muma's hand.

Most of the crossbows made in the history of human beings on earth are mostly divided into three parts: "arm", "bow", and "machine".

The "arm" is generally wooden, the "bow" is horizontal to the front of the arm, and the "machine" is mounted at the back of the arm. The most important part of the crossbow is the "machine", which is generally made of metal.

Therefore, under Joseph's current conditions, there was no way to make a decent crossbow machine, so he could only use a thick wooden rod as a crossbow arm, another thinner wooden stick with a certain elasticity tied to the crossbow arm with a rope as a crossbow bow, and an animal tendon as a crossbow string.

As for how to solve the problem of not having a metal crossbow machine, Joseph used a stone knife to slowly pull a small hole in the back of the crossbow arm and drive it into a thin wooden nail. Find a small Y-shaped stick of suitable size, fork it on the bottom of the wooden peg, and tie it with string. A small wooden stick is tied to the crossbow arm below the junction of the three prongs of the Y-shaped stick.

Every time the "Joseph crossbow" is fired, the crossbow string should be pulled back, the string should be hooked with a wooden nail, the arrow should be loaded, and then the lever principle should be used to press down the rear end of the Y-shaped wooden stick and the fork on the Y-shaped wooden stick, and the crossbow string should be broken upwards to make the crossbow string detach from the wooden nail and move forward to drive the crossbow arrow to fly away from the crossbow body.

Somewhere in the forest, Joseph was lucky enough to encounter a mutilated, feline-like white skeleton of the "Tiger of Eden" with several black holes in its ribs.

It was an animal the size of a cheetah on Earth, with a black coat. However, its outer skin is the same as that of some animals on Proxima Centauri B, with tiny scales similar to that of lizards, and its mouth is also four-petaled, each with a set of teeth.

At the same time, its stout black tail is very long, almost the same as its body length, and at the end of the tail, it is a bare white hard pointed bone, 30 centimeters long and five centimeters wide, like a double-edged dagger, very sharp.

The four sets of teeth of the "Eden Tiger" are somewhat similar to those of the Earth Tiger, except that the front teeth of the "Eden Tiger" are not the four of the Earth Tiger's four but two and wider, and each set of teeth has six sharp fangs.

This "tiger" is one of the largest and most ferocious beasts known on the continent of Eden, and its brain is more developed than cold-blooded animals such as "Siwa", so there are basically no natural predators, and even "Siwa" has to retreat when it sees it, until humans arrive on this continent.
