If the ultimate goal is set to 'improve the root bone', or 'bypass the root bone and quickly improve the four-dimensional attributes'.

So.

The initial idea is that there can be three routes -

The first is to find the treasures of heaven and earth that can enhance the root and bone. This will be the task of the ‘Tian Zi Secret Agent’ that will be formed by ‘Tie Dan Villa’ in the future.

The second is to find the magical skills that can enhance the root and bones. This is the task of the "Di Zi Secret Agent" that "Tiedan Villa" will soon form in the future.

The above two points are limited by the initial construction of "Tiedan Villa", which cannot be carried out for the time being. It is still under preparation, and the plan remains on paper.

But the third way is feasible and can be tried in a short time.

"I am sitting on this huge treasure house of the original fairyland. There are countless exotic flowers and herbs growing in it. There are herbs that are the same as the real beams, and there are also a large number of different herbs with unknown medicinal properties."

"If we could identify the medicinal properties of the exotic flowers and herbs in the original fairyland one by one, and then combine them with various medicinal materials in reality, we might be able to refine a panacea that can enhance the root and bones, or it can increase internal strength faster, and even more

Medicinal decoctions and elixirs with fast growth properties."

If you want to do this, you must have the spirit of Shennong who tasted hundreds of herbs.

Of course Cao Xin was not willing to risk his own life.

He has other methods.

"There are so many evil people in the world. After the initial construction of 'Tiedan Villa', more and more evils, big and small, hidden in the corners of Xijing City were unearthed by Lu Ji and others."

"Instead of killing these people directly, it is better to recycle the waste and give me a trial of the properties of the original fairyland herbs."

But there are two problems in doing this.

First, it is much more difficult to kidnap and arrest people than to directly kill them. Cao Xin is not an official, and ‘Tiedan Villa’ is not a government official. Arresting and taking people cannot be done in a fair and just manner, which will be much more troublesome.

Moreover, it may be easy to capture them alive, but how to transport them quietly from Xijing City?

It's not easy.

also.

Even if it is shipped out, where should it be hidden, how should it be managed, and how should the problem of distance be solved?

There are problems in every aspect.

Cao Xin went over and over on these issues, thought about it several times, investigated by secret agents, and conducted on-site research by himself, and finally formed a preliminary plan, a method that had the best of both worlds——

"Worry-Free Cave!"

…

Xijing City has a population of more than two million, with rich people and nobles everywhere. The wealth and powerful people gather together, giving rise to many industries——

Luxury.

Delicious food and wine.

Gambling brothel.

Cuju horse racing.

This is all common.

But people's hedonic threshold will always increase unknowingly, and there will always be people who pursue more excitement.

So in the darkness, in Wuyou Cave, there are corresponding industries growing.

…

The largest force entrenched in Wuyou Cave is the 'Ghost Fan Tower', which is most famous for its slavish business of human trafficking, training of thin horses.

But apart from the 'main business', no one knows if Guifan Tower has other industries.

For example, gambling houses.

For example, the arena.

Is there a "Ghost Fan Tower"?

Not sure.

But they all exist in Wushou Cave.

These businesses are operating openly and openly in Wuyou Cave, and no one knows their background.

However, being able to operate for a long time shows that the background is not shallow.

Even if it has nothing to do with "Ghost Fan Tower" on the surface, secretly, it may be inextricably linked.

However, no one is digging deeper, or they are pretending to be ignorant. At least on the surface, it has nothing to do with Guifan Tower, but there are still a large number of customers who come here looking for excitement.

Especially the arena.

Fighting with fists and fists, life and death duels are what many rich and noble people who are pampered and lack stimulation like to see.

Here they can release their passion to a great extent, and coupled with gambling, punches and kicks, victory or defeat, life and death, it will make your heart beat faster.

There are ordinary arenas in Xijing City. For example, one of Zheng Boqian's brothers in the martial arts gym went to the boxing gym to fight because his family was poor, just to earn some money to support his family.

It ended with a few broken ribs.

The situation at home is getting worse.

Thanks to Cao Xin's support for Zheng Boqian and Zheng Boqian's help, he was able to survive.

but.

Although this person is miserable and the arena is dangerous, it is set up in Xijing City on the ground after all, so there are many rules to avoid the situation of the arena players being beaten to death on the spot. Generally speaking, only the winner is determined, not life or death. .

Click till then.

Therefore, many people are not satisfied with watching it.

But these are potential customers.

After screening, these people were invited to come to the Wuyou Cave, underground, in the darkness, to watch a more exciting, more brutal, and more bloody unlimited life and death arena.

Here, two people take the stage, one lives and the other dies.

It's a matter of life and death!

In such a life-and-death struggle, even if both parties are ordinary people, the desperate madness, punches and kicks, chickens flying and eggs flying, and blood and flesh flying everywhere can still arouse great excitement in the audience.

In addition, there are fights between beasts and beasts, humans and beasts, women and men, and men and women.

The tricks are different, but equally exciting.

Occasionally, you can see masters fighting.

These masters appear here for various reasons, and the trapped beasts still fight, which is particularly exciting.

‘Xuanwu Cave’ is such an underground boxing gym.

It is located in the north of the city and is one of the largest underground arenas in the "Wuyou Cave".

The ruins of the ancient city have undergone natural evolution and artificial hollowing out and consolidation, and finally formed a cave with a vast space, with a total area of ​​about a thousand square meters and a height of about seven or eight meters. Audience seats are set up around it, and the middle area is a battle arena. .The passages around the cave extend in all directions, like a spider web, and can be exited everywhere, leading to the underground culverts of Xijing City.

It's hard to be surrounded.

This day.

It's business time in Xuanwu Cave.

…

"Wait a minute, who is it?"

An entrance to Xuanwu Cave was brightly lit and guarded, and a dry and skinny old man was stopped.

"Not allowed in?"

The old man's voice was hoarse.

"Let in."

"But seeing as it's your first time here, we need to make our rules clear."

"First, Xuanwu Cave is divided into east and west areas. The admission fee for the west area is 50 taels. The admission fee for the east area is 10 taels. You can enter with a guard."

"Second, weapons are not allowed to be brought in."

"Third, if you don't have a recommendation from a distinguished guest from the East District or an invitation from the Xuanwu Cave, you can only go to the West District. There is no need to verify your identity in the West District. If there is a conflict, the Xuanwu Cave will not be responsible and will not be allowed to enter again in the future."

The rules of Xuanwu Cave are almost like no rules at all.

Open the door to welcome customers from all over the world. If you have money, you can get in.

But there are also precautions to protect the personal and property safety of the real rich. Those with clear identities, rich or noble, are placed in the East District, where all conflicts are prohibited and personal safety is ensured.

The West District is much simpler. All cattle and horses can enter. Xuanwu Cave is not responsible for their safety. They will attack them if they want and kill them if they want. At most, they will be blacklisted and will not be allowed to enter next time.

This is easy to understand.

For example, a character like the old man who doesn't know where to follow is too difficult to control.

Once they are mixed together, if evil takes over and they go on a killing spree inside, killing all the rich and noble patrons, even if they just bump into each other, the Xuanwu Cave signboard will be ruined.
