Rules of Forbidden Zone 10:

The first rule is, no arguing back. If someone insults you, you must accept it.

The second rule is, on the first night after entering, tell Forbidden Zone a secret that only you know.

The third rule is, you must kill a living creature once a day.

This is a secret Old Master Li once gave to Qing Chen.

But these three are not all the rules of Forbidden Zone 10; there is also an unknown fourth rule.

This fourth rule is Knight's masterpiece.

Forbidden Zone 10 used to be Fire Pit's pasture, with many useful and rare plants and animals.

At that time, Forbidden Zone 10 only had three rules. Fire Pit, who mastered these three rules, could move freely and happily inside.

Even with just Wind Jun pollen applied, no wild animals attacked them, allowing them to freely harvest the exotic flowers and plants within the Forbidden Zone.

Later, the Knight Order, to claim the Dragon Fish within Forbidden Zone 10 for themselves, captured a Koshima family expert and planted them in the Forbidden Zone, forcibly creating the fourth rule.

Since then, Fire Pit has been unable to go to Forbidden Zone 10.

Until now, Fire Pit still doesn't understand what the fourth rule is. Every time, the Grand Elder has to go and try it personally, then get bitten all over by poisonous insects.

If the Grand Elder wasn't already A-Class, and hadn't gone deep into the Forbidden Zone, they would have been poisoned to death long ago.

Planting rules is very particular. You need to know who the person planted is, what kind of person they were in life, what they liked best, and what they hated most, to grasp the direction of exploring the rules.

Knight did this extremely secretly; outsiders knew nothing about it.

They didn't even know how this fourth rule came about; they thought someone had accidentally died inside.

What's more, after Knight secretly planted that Koshima family expert, when the fourth rule was born, he specially went to the southwest snowy mountains to advise Fire Pit not to go there anymore, saying safety first.

He even had a heart-to-heart talk with the previous generation's Grand Elder, advising the Grand Elder not to risk their life for money.

That appearance of "I'm so concerned about your safety" almost made the previous generation's Fire Pit Grand Elder furious.

If you really care about Fire Pit, why do you do such a wicked thing?!

Only then did Fire Pit know that Knight was scheming against them.

Later, Fire Pit couldn't figure out the fourth rule, and that fourth rule was extremely effective in trapping people, so they sold two of the three rules to the Chen Family, hoping to trick the Chen Family.

Shadow laughed in the carriage: "Actually, the tea I grow is also picked from Forbidden Zone 10. At that time, the Chen Family was also cunning. They knew that Forbidden Zone 10 had many treasures, and they knew that there couldn't be only two rules, and Fire Pit couldn't be that kind-hearted, so they publicized the two rules they bought."

Shadow: "As soon as the two Forbidden Zone rules came out, it deceived many Wildlanders, Wilderness Hunters, and Federation Metahumans to go for gold, resulting in countless casualties, and finally tested the third rule. But what the fourth rule is, no one knows to this day. Qing Chen, your master must have told you what the fourth rule is."

Qing Chen looked at the Steam Train ceiling: "What? I don't know anything."

"It's okay," Shadow said with a smile, "Xiao Mengqian is an ordinary person. If he doesn't know the rules, he will surely die when he goes in. You'll have to tell me sooner or later; I'm not in a hurry."

Qing Chen changed the subject and asked, "How was Forbidden Zone 10 formed?"

Shadow said with a smile, "Forbidden Zone 10 is a very legendary place, formed by a Demi-God who fell there."

"Which Demi-God?" Qing Chen asked in doubt.

"The founder of the Hu Family Intelligence Agency, Hu Shuo," Shadow said, "He died a natural death of old age, but his tomb was chosen in that place. Forbidden Zone 10 was numbered quite early; at that time, the Federation didn't know that B-Class or higher Metahumans would form Forbidden Zones after death. So, the first rule should have been formed by Hu Shuo. Some people say it's because he had a very bad temper, so he didn't like others arguing with him."

"Who formed the second rule?" Qing Chen asked.

"It was an Awakened One named Zhang Baogen. It is said that he was an orphan adopted by Hu Shuo, and also the second chairman of the Hu Family Intelligence Agency after Hu Shuo. After his death, he asked people to bury him next to Hu Shuo to accompany this elder who had shown kindness to him," Shadow said.

"What about the third rule?" Qing Chen felt strange. What kind of person would leave a rule that requires killing a living creature every day?

Shadow said, "It's not clear who left the third rule. It's said to be an A-Class expert who went to pan for gold and was killed by the rules deep inside... From this, you can also see how dangerous the depths of Forbidden Zone 10 are."

Forbidden Zones numbered in the top ten are the ten most dangerous places in the Federation. You can search online to see the legendary stories of these 10 Forbidden Zones, just like the Bermuda Triangle, Lop Nur, and Kunlun that Outer World has been talking about for hundreds of years.

Of course, the most dangerous are numbers 001 and 002, and many people go there to explore every year.

After the time-travel events, Time Travelers, out of curiosity about the Inner World, also yearn to explore these places on foot...

...

...

At this time, the Guardians' Union members who boarded the train earlier began to share their food on the train. Someone came to give Shadow two apples, a handful of melon seeds, a bag of oranges, and a bunch of bananas.

It looks like they're out on a picnic.

It has to be said that the current Home Families are in good spirits, looking energetic.

Ma Jingjing and others looked at this scene and muttered in a low voice, "What's the relationship between these people?"

Yi Wenbo shook his head: "I don't know..."

The Golden Family member named Wang Dingye came over and sat next to Qing Chen and whispered, "Family member, the Black Family Member asked you to meet us. Is there anything else to tell us?"

Although there is a clear hierarchy in the Guardians' Union, the organizational guidelines advocate equality for all, so this Golden Family member didn't put on airs for Qing Chen, a Blue Family Member, but was instead exceptionally friendly.

In Luo Wanya's words: "The Guardians' Union helps each other and treats everyone equally. You Golden Family members are not bureaucrats but protectors of the Guardians' Union. When you encounter danger, you should be the first to protect the Blue Family Members, Green Family Members, White Family Members behind you..."

Overall, the Guardians' Union doesn't have the bureaucratic problems of large organizations yet. Because everyone is fresh blood, the atmosphere is very harmonious.

It may change in the future, but not yet.

Qing Chen smiled, "You're going to City 13 to develop a property company, right?"

Wang Dingye laughed, "Yes."

"Do you have a lot of money on you?" Qing Chen asked.

"Ah, this," Wang Dingye thought that Qing Chen wanted to borrow money, so he said hesitantly, "The Black Family Member said that City 22 is getting better, and life will be better in the future. But everyone is still struggling, and we don't have much money on us. This time, we traveled a long distance with the Great Leader. The gold coins were pooled together from everyone's jewelry, and the fruits were gifts from Home Families in the neighborhood. Fortunately, we met you, and we still have more than ten gold coins left... I was planning to use these ten gold coins to buy some weapons in City 13, but if you need them, I... I can give you half! After all, you helped us get free tickets."

Qing Chen smiled and took out three gold coins from his pocket and handed them to Wang Dingye, "I don't need your money. I'm afraid you won't have enough money to spend. You also work hard for our Guardians' Union. You must not suffer too much when you're out. The price of medicines in the Federation has recently risen again, and if anyone gets injured, it's good to have some money for medical treatment. Also, take some money to buy some medicine in advance."

In the future, when various Conglomerates discover the threat of the Guardians' Union, they will definitely try to cut off all the supplies of the Guardians' Union.

This day won't be too far away, so Qing Chen asked Luo Wanya to consciously and in batches buy medicines from the city and store them in safe places.

Even if the medicine expires, we can't wait until we need it and then find we don't have any.

This is also a precaution.

At this moment, Wang Dingye looked at the three gold coins in his hand and was immediately moved. This is family!

What pure family!

Taking a Steam Train ride, not only didn't spend any money but also got three gold coins!

Qing Chen said in a low voice, "All right, go back and rest quickly. We're almost at City 13, and you still have a tough battle ahead. Also, don't be too enthusiastic towards me; my identity is hidden, and it will be inconvenient to act if my family identity is discovered."

"Okay!" Wang Dingye moved and returned to his team to sit down.

On the other side, Ma Jingjing and others watched this scene. They didn't know that Qing Chen knew these people, and they didn't know that these people were from the Guardians' Union.

They only saw Wang Dingye taking the fruit over, and then Qing Chen gave them three shiny gold coins...

Ma Jingjing and others looked at each other.

"Why did that kid give these people gold coins?" Yi Wenbo asked in doubt.

"I don't know. I just saw him take the fruit over and then get gold coins back. Do you think we can also exchange the gold coins?" Xiao Yu said.

This is like the story of the golden axe and silver axe. As long as you are sincere enough, you will be rewarded...

To be honest, with their understanding, they couldn't explain why fruits could be exchanged for gold coins.

Yi Wenbo immediately took a pile of fruits and peanuts towards Qing Chen. He put the fruits on Qing Chen's table and said with a smile, "We have a lot of things, so we'll share some with you."

After saying that, he waited silently.

Qing Chen looked up at him for two seconds, "Thank you."

Yi Wenbo stood there waiting for a while... That's it? Where's the gold coin?

Qing Chen asked with a smile, "Anything else?"

"No... nothing," Yi Wenbo was stunned for a moment and turned to leave.

What the hell is this? Forget about not getting the gold coin back, but I also spent some fruit; am I being foolish?!

Back at his seat, Ma Jingjing whispered, "Did you get anything in return?"

Yi Wenbo said expressionlessly, "A thank you."

At this moment, three Airships suddenly flew over from the distant sky and quickly passed the Steam Train, continuing to fly south.

Each one was a military Class B Airship, and each was carrying a full load of ammunition.

Qing Chen looked at the Airships from afar and said, "Strange, there's no unit marking paint on these three Airships. Are there any civilian Class B Airships in the Federation?"

Class B Airships are military and must be painted with battle numbers.

Shadow smiled, "They erased the numbers, naturally, they don't want to be discovered who killed you."

"Killed me?" Qing Chen was stunned, "How did they know my whereabouts?
