Everyone's on a time-travel adventure! I'm raising city beasts in a post-apocalyptic world

In the end, 10 people chose to become the Demon Suppressors and Zhao Gao's subordinates. Lin Feng, considering Zhao Gao's loyalty and the fact that he had earned a lot of Ghost Crystals for him, provided them with a large number of mutated beast sacrifices, which raised the Demon Suppressors' strength to level 4 in one go. They transformed from ordinary mortals into Black Iron Humans with a lifespan of 800 years and each person's strength exceeded 10 tons.

The Black Iron level possesses a special power, different from the spiritual energy of the Awakened. It is a power similar to the power of blood and qi. This power is more effective against the supernatural and can cause greater damage to the supernatural. However, the main purpose of this power is to enhance one's own foundation.

The way to improve your strength is also very simple: refine. Refine your foundation and increase your own source. Consume mutated beast meat, fruits, and grains that can increase attributes. Basically, any food that can increase attributes can increase your level progress. You can also refine the power of your source. To put it simply, you can add points using your professional experience points.

Once you reach your limit, you can naturally level up. This is where the differences between professions come into play. For example, in life professions, the experience required for each level up is basically fixed. Of course, if a lucky person obtains rare and precious materials, making their foundation deeper, or is appointed a position by Lin Feng, the experience required for leveling up will increase. However, in return, after each level up, their strength will be much greater than that of others.

It takes 100 experience points to go from level 0 to level 1, and the same applies to levels 2 and 3. However, when you go to level 4, it's a transformation from a mortal to an iron-level character, and the number of experience points increases a hundredfold, requiring a full 10000 points.

The upgrade requirements for combat professions are several times higher than those for life professions, but the power after transformation is also different. After a life profession transforms into Black Iron, its lifespan can be increased to 800 years, and its basic strength can reach a terrifying value of 5 tons. However, compared with other powerful professions, especially in terms of combat power, the difference is like night and day.

Professionals also have simple ways to gain experience.

Life professions, such as blacksmithing, grant one point of professional experience for each successful crafting of a weapon or tool of the corresponding level. This experience is reduced by a factor of 10 for each lower level. Once you reach the Black Iron level, crafting ordinary weapons grants no experience.

The same applies to combat professions. Each kill of a creature of the same level grants 1 point, with the points decreasing by 10 times for each lower level. After reaching Iron Level 4, hunting mortal creatures below level 4 grants no experience.

Since Lin Feng reached Black Iron Level 5, the method of obtaining evolution points has changed. He now gains 1 Black Iron level evolution point for each level 4 Black Iron level creature he kills, and 10 points for level 5...

However, killing mortal creatures below level 4 only yields 1 ordinary evolution point, which cannot be used for the evolution of Black Iron-level natal beasts. It can be used as energy to meet the daily needs of the beasts, but the consumption is very high, especially for Little Xuan, who is a major energy consumer.

If it weren't for the Gold-Eating Ants searching the entire map for ores and scrap steel to prepare enough food for him, he would have to consume 4 ordinary evolution points every day, which is equivalent to hunting 4 mortal creatures every day.

Lin Feng specially brought a bunch of snacks to coax Bai Zhirou. This girl was indeed not very bright; she told him everything as soon as she saw the snacks. If it were just a few days after he transmigrated, Lin Feng would have tricked her into eating him long ago...

Her profession is Frost Sword Immortal. After she reaches the Black Iron level, she needs a full 5000 experience points to level up, which means she has to kill 5000 monsters of the same level to advance to the next level. In contrast, Zhao Gao only needs 1000 points to advance to the next level, and Black Iron level life professions require even less, only 100 points.

As for how much experience Lin Feng himself needs...

Sigh, it's all tears when I think about it, better not to talk about it...

Fortunately, evolving his destined beast will give him a large amount of essence (attribute points), propelling him to level up quickly...

Of course, if awakened individuals are not afraid of side effects, absorbing the Mysterious Crystal is undoubtedly the fastest way to level up. However, the higher the level, the greater the side effects and the more terrifying the consequences. Non-awakened individuals, even if they become professionals, still cannot absorb the Mysterious Crystal.

There is only one outcome: either die or become a new, bizarre creature.

Of course, Lin Feng did try to upgrade using the Ghost Crystal. As for the consequences of absorbing the Ghost Crystal, none of the girls who were playing the zither and dancing escaped. He ate them all in one night and sang songs all night long.

Soon, Zhao Gao brought over a Japanese minor leader, who had a bruised and swollen face and a broken arm. Zhao Gao shoved him towards Lin Feng.

"Your Majesty, I have found out."

Zhao Gao kicked the leader so hard that he knelt on the ground. The man grimaced in pain but dared not make a sound.

"This group of Japanese came from a large caravan called the Osaka Caravan. According to him, there were at least 4 people in that camp, and there were more than one caravan like this in the area, but four."

Lin Feng raised an eyebrow: "Four? Go on..."

Zhao Gao nodded: "They have an emperor who possesses a strange object, what is it called...?"

He kicked the petty thug: "What's your name?"

The junior leader answered tremblingly, "Sir, it's called the Amaterasu Mirror. It can contact all the Japanese within a thousand miles. As long as the Japanese are within this range, the Emperor can sense them and communicate with them. We were all summoned by the Emperor and moved in four separate caravans..."

Lin Feng stroked his chin, deep in thought.

"Anything else?"

"And... there's also an Onmyoji by the Emperor's side... who possesses an ancient scroll of sealing demons, capable of mass-producing scrolls that seal away the supernatural, sealing those supernatural beings within the scrolls, and then parasitizing the sealed supernatural beings within people's bodies... thus, one can... one can master the power of the supernatural... and become a demon tamer..."

Those who had gathered around to listen gasped in shock.

"Depend on……"

"Controlling the bizarre, this...?"

Lin Feng frowned. Using strange power? This ability is too strong! He had just found the power to become a professional, but the Japanese had actually obtained the power to become a master of strange things. But is strange things so easy to control?

So he asked, "And the price?"

Snapped……

"Speak..." the underling said hastily after being slapped by Zhao Gao again.

"After parasitizing a supernatural entity, it consumes a person's life force... The more times the supernatural entity is used, the faster it is consumed... That's why supernatural beings don't live long... To reduce the mortality rate, supernatural beings let the supernatural entity devour other people as nourishment... So... So they're capturing people everywhere..."

After he finished speaking, he didn't dare to look up at Lin Feng.

Lin Feng didn't speak immediately. He looked at the distant wilderness and remained silent for a while. He finally understood why he rarely saw other Blue Star people's caravans after entering this area. It wasn't that they didn't come, but that they came and failed to leave, leaving only scattered caravans of survivors.

If I'm not mistaken, they were all captured by the Japanese and used as nourishment for some strange creature.

"Take him away and sacrifice him!"

Zhao Gao responded and dragged the minor leader away.

Wang Lie walked up to Lin Feng with a solemn expression: "Four caravans, each with a scale of over 100,000, and they possess a unique artifact that connects all the Japanese, plus the means to mass-produce the Master of Deception... This is a scale that we can no longer confront head-on."

Lin Feng turned to look at him: "I didn't say I wanted to confront him head-on."

"So what are your plans?"

Lin Feng: "Keep developing. They outnumber us, so a head-on confrontation would be suicide. They can't stay together forever. With so many people, food, drink, and shelter are a huge problem. They'll have to come out to find supplies eventually, and there will be times when they're alone. Then... hehe..."
