The 'internal forces' seem to be these 'qi' in the body.

Try it and see if it works.

Forget it, it's too late today, there are still many things to do tomorrow, and it's a bit of a loss to take it now.

After all the things at hand are done, let's concentrate on eating Qi Refining Pills and cultivating.

After Lu Chao confirmed that the curtains were closed, he turned on a small light, picked up another book, "A Brief History of Martial Arts", and read it.

After reading a few pages, Lu Chao's eyes widened with a surprised expression.

"Is this a novel?"

After repeated study and thinking, Lu Chao finally came to a conclusion.

This is not a novel, but the real history of martial arts development in the high martial arts world where the martial artist is!

That warrior, the warrior who killed an adult wolf with one punch, judging from the description in the book, is indeed not the person who was 'hijacked' from the same world as Lu Chao.

The world where the warrior is located belongs to a parallel world on Earth!

That's why the banknotes found in his safe are so weird.

"A Brief History of Martial Arts" describes the history of the development of martial arts in their world.

These histories are obviously completely different from the histories that Lu Chao knows.

The reason for this difference is that the earth of the world where the man lives has discovered an interstellar gate during the excavation of an ancient mausoleum decades ago!

A kind of interstellar portal that can only teleport lifeforms (corpses) and special alien minerals and ancient ruins treasures.

The scientists' research inadvertently triggered one of the stargates, and then one after another stargates on Earth were activated by this stargate.

The Stargate cannot be closed after activation, at least with the human technology of their world.

The Stargate connects to distant galaxies, so far away that Earth technology can't even observe them.

Connected to some of the planets in those galaxies, the dark energy on those planets is extremely rich, and there are actually footprints of ancient humans! But most of them are relics from hundreds of thousands of years ago, or even more ancient times.

Governments send teams into their countries' interstellar portals to find the true origins of humanity, as well as the various available extraterrestrial minerals and treasures in ancient ruins.

All kinds of thermal weapons, electronic products, and corresponding equipment and tools cannot be teleported through the stargate, and even if they are carried on the body, they will turn into metal dust after the teleportation is completed.

Even the clothes on human bodies disappear on their own.

After repeated attempts, the humans of Earth discovered that only lifeforms, corpses, alien minerals, and some special treasures found could be teleported through the Star Gate.

The team sent can only make clothes from local materials after arriving, as well as a variety of primitive tools to explore and colonize the destination planet.

Some small colonial towns were quickly established on the alien planet, and just when the colonial towns were about to develop their basic technology, the alien base was suddenly attacked by a large-scale alien beast.

The black wolf that Lu Chao saw before was a kind of alien beast.

With no thermal weapons, no weapons of mass destruction, and humanity's colonies were destroyed overnight under the attack of alien beasts with dark energy armor, these terrifying cosmic races even used the stargate to break into Earth and wreak havoc on it.

The dark energy armor possessed by the alien beast, that is, the black mist-like thing outside the black wolf's body, could not be broken by human firearms at all, and it was necessary to use high-powered missiles and even nuclear bombs to clear the field to prevent the invasion of the alien beast army.

In subsequent research, scientists found that with the opening of the interstellar gates, the rich dark energy in the distant universe planets also escaped into the Earth's atmosphere with these interstellar gates.

The dark energy claimed by scientists is called aura by cultivators in Huaguo, and elemental power by demon cultivators in Europe.

A cultivated martial artist can use his fist to penetrate the armor of the alien beast that invades the earth with his fist, which is much more effective than a thermal weapon, and will not cause damage to the human world.

In order to move the battlefield outward, resist the invasion of these cosmic races, and compete for the mineral resources of the alien planet and the treasures left by ancient humans in the ruins, human beings began to train warriors on a large scale with military formation, and sent them to the interstellar gate to the alien planets in the distant galaxy to fight against the alien beasts.

There are huge deposits of dark energy on alien planets, and the number of alien beasts living on alien planets is extremely large, and the number of alien beasts on any planet has reached tens of billions.

Some high-level alien beasts have condensed dark energy crystal nuclei in their bodies, which are valuable resources used by humans for cultivation and making various pills, and have also become the focus of human warriors.

After being studied by scientists, the carcasses of ordinary alien beasts have been confirmed to be non-toxic and harmless, and can be eaten.

However, eating the meat of the alien beast can not increase the cultivation of the martial arts, but the meat of the alien beast tastes particularly delicious. In the beginning, these hunted beasts sold for sky-high prices on Earth, becoming special offerings on the tables of the privileged and wealthy.

With the increase in the number of warriors and the expansion of colonies, the number of killed alien beast corpses brought back to the earth is increasing, and the price of alien beast meat has gradually become more affordable, and it has even been placed in supermarkets and become a delicacy on the table of ordinary people.

"I knew that the meat of that beast was so delicious, I should have kept a piece to taste." Lu Chao couldn't help but regret a little after seeing this.

After cursoryly flipping through the first few chapters of "A Brief History of Martial Arts", Lu Chao speculated that the world where the martial artist was located was closer to the world in the dimensional space where he was now, and there were strange beasts that could be cultivated.

Maybe there's a dark energy vein in the woods.

Speaking of which, if that warrior didn't die, it would be better to survive in this wood.

The warrior's family was not attacked at night that night, and after the warrior figured out the situation in the woods and took appropriate countermeasures, their family's chances of survival were definitely higher than that of Lu Chao's father and daughter.

It's a pity that he died.

Fortunately, he brought the basic training technique "Body Forging Technique" and the basic combat method "Concussion Fist", which happened to be left to Lu Chao. also brought a copy of "A Brief History of Martial Arts", which let Lu Chao know what their so-called martial arts cultivation was all about.

Lu Chao remembered that there seemed to be these books for sale in the supermarket, but the prices were all more than tens of thousands of gold coins, which was not something he could afford at all.
