Undead buff: I am really invincible

Take out a knife from the backpack, Lin Feng cut open the head of the alien beast and took out the crystal core.

The crystal core is the crystal formed by the essence of the alien beast.

The alien beast is not a species of this world.

Thousands of years ago, there was no martial arts practice, and humans only developed technology.

But in the first year of martial arts, huge space cracks appeared all over the world.

Endless alien beasts emerged from the cracks, wreaking havoc on the human world.

The powerful technological weapons lost their deterrence and could not kill the alien beasts.

Just when humans were about to become extinct, humans discovered that the ancient martial arts that could not be practiced before had exerted a powerful power.

After 50 years of martial arts, humans began to counterattack.

After joint research around the world, the first practice method, 18 body training methods, was finally launched, and the era of national practice began.

Later, martial arts masters discovered that the crystal core in the mind of the alien beast had the effect of increasing the speed of practice. The higher the level of the crystal core, the greater the effect.

Moreover, many precious medicinal materials and minerals appeared in the wilderness, which were very useful to humans, and humans began to counterattack.

After 200 years of martial arts, humans finally regained their place in the world.

Cities rose from the ground, with protective shields inside to resist the attacks of alien beasts.

However, humans only have the power to protect themselves. The city belongs to humans, and the outside belongs to alien beasts.

If humans want to leave the city, they must have strong strength.

Therefore, warriors have become the noblest profession of humans.

Lin Feng is a warrior of the fourth level of body refining.

There are nine levels of body refining, which are respectively tempering the skin, flesh, tendons, bones, marrow, five internal organs, six internal organs, twelve meridians, and Ren and Du meridians.

After the whole body is tempered, and the Dantian is finally opened, it can break through to the Qi Sea Realm.

Lin Feng went out of the city this time because of the actual combat trial of the martial arts school.

The trial is not an exam, but a real fight with alien beasts, which will kill people.

Lin Feng's father died at the hands of alien beasts. From then on, Lin Feng vowed to kill all the alien beasts.

...

Lin Feng took off all the crystal cores, ignored the tattered clothes on his body, and sat on the ground.

After killing more than a dozen fourth-grade beasts, Lin Feng had 520 energy points and could continue to upgrade.

Click the upgrade button, the energy points decreased, and Lin Feng's flesh began to be tempered.

After the flesh was tempered to perfection, Lin Feng still had 300 energy points, and he could continue to upgrade and continue to temper the tendons.

Soon, the tendons were also tempered to perfection.

As the blood and qi were circulated, a faint white fluorescence appeared on Lin Feng's skin, which attracted attention. This was the performance of perfect body refining.

Feeling the power in his body, Lin Feng couldn't help but sigh: "I don't know how much I suffered when I was refining my body. Although it's very easy now, I always feel that something is missing, painful, I miss the feeling of pain so much."

After the training, Lin Feng walked towards the valley entrance.

Looking around, there was no one at the valley entrance, and Chen Qiang and others had already left.

"Chen Qiang, Hu Xia, you are all ready to die." Lin Feng was furious.

Lin Feng was a vengeful person. They dared to kill Lin Feng. The three of them were already dead in Lin Feng's heart.

There was still a week before the end of the trial.

Lin Feng was in no hurry to go back. If he wanted to kill the strange beasts, the wilderness area was the best place. Lin Feng was not going to waste it.

Lin Feng now had a perfect third-grade cultivation, and with the power of the black iron battle body, he could burst out 700kg of power.

In addition to the increased defense of the black iron battle body, Lin Feng was not afraid even if he faced an ordinary seventh-grade warrior.

[By the way, the best app for reading and listening to books at present, install the latest version. ]

Heading deep into the wilderness area, Lin Feng was going to find a few strange beast gathering places to earn some energy points.

If he looked for them one by one, it would be a waste of time.
