Roxy: "Haha, who told you you can't stay in Orario for long?"
Esdeath: "Are the monsters in the Underground City very strong?"
Roxy: "The upper levels are relatively weak, but the further down you go, the stronger the monsters become. Yesterday, Lin Che single-handedly killed the Floor Boss Goliath on the 17th floor!"
Esdeath: "Is the Floor Boss very powerful?"
Roxy: "Yes, it has Lv4 strength, enough to rival ordinary Servants in the Type-Moon World."
Esdeath: "With so many powerful monsters, I can definitely kill to my heart's content. I want to go to Orario now too."
Hestia: "Next time, wait until they return from their expedition.".
After entering the Underground City, they didn't waste time on the upper levels, and went straight down according to the map.
When they encountered monsters along the way, Saeko Busujima, Irisviel, Sera, Lisellote, and Jiu Yu Wu Mi would deal with them.
These Lv1 small monsters were perfect for them to practice on.
Anyway, with Lin Che and others watching their backs, there was no need to worry about safety.
After half a day, everyone arrived at the eighteenth floor.
Lin Che and the others had been here yesterday, so it wasn't a big deal.
But it was the first time for Roxy and the others, and they were all stunned by the scenery here.
Not only her, but the friends watching the live broadcast in the group were also extremely surprised.
Who would have thought that there would be such beautiful scenery in the underground world.
After resting on the eighteenth floor, they continued to go deeper.
The environment on the nineteenth floor was similar to the eighteenth floor, mainly Forest.
According to the guild data, from this floor onwards, up to the twenty-fourth floor, it is collectively called the 'Great Tree Maze'.
Because it is a Forest environment, there are many plant-type monsters.
For example, Dark Mushrooms, poisonous mushrooms that spread poisonous spores everywhere.
In addition, there were also many traps.
Everyone walked in the damp and dim Forest, feeling very uncomfortable.
Roxy couldn't help but say, "If we set a fire, can we burn all the monsters on the entire floor?"
"Please stop your dangerous thoughts. Once a fire starts, this floor will become a huge oven. We will either be roasted to death or suffocated by smoke!" Lin Che glared at her, his eyes looking as if he was looking at an idiot.
Roxy's little face blushed, and she argued, "We have ice magic and barrier magic, which can block high temperatures and smoke."
This time, before Lin Che could speak, Merlin answered for him, "But did you forget about 'abnormal state'? If the floor is severely damaged, the Underground City will refresh a monster called 'Zagnate'!"
Roxy was speechless and stopped talking.
In fact, with their current strength, they could completely kill Zagnate.
But that was without any burdens, with Lin Che and Roxy, plus Merlin and the other three Servants.
With five people working together, let alone Lv6 monsters, they could even fight Lv7 ones.
But not now, there were still ordinary people like Saeko Busujima and Jiu Yu Wu Mi in the team.
Since entering the thirteenth floor, Saeko Busujima and the others had not made a move.
There was no way, they couldn't deal with Lv2 monsters yet.
Roxy seemed to see the disappointed expressions of Saeko Busujima and Jiu Yu Wu Mi, so she came to their side and said, "In my world, besides magic, there is another cultivation system called Fighting Spirit. Do you want to cultivate it?"
Saeko Busujima's eyes lit up when she heard this and said, "Can I become strong quickly?"
Roxy nodded and said, "Yes, the so-called Fighting Spirit is a method of using Demon Power. By wrapping Fighting Spirit around your entire body, you can strengthen your physical functions!"
"I'll learn!" Saeko Busujima said directly.
"I'll learn too!" Jiu Yu Wu Mi also said.
Not only her, but even Sera and Lisellote also expressed their desire to learn Fighting Spirit.
Although they were advanced artificial humans and were given personalities, they had some basic martial arts and magic, but in Orario, they were still too weak!
Not only that, their talents were also limited, and they might not even be able to grow into advanced adventurers in the future.
The only way was to learn cultivation systems from other worlds, so as to complement each other, just like Lin Che.
"Alright, but it's best to learn Fighting Spirit together with a set of martial arts. The most famous martial arts in our world are the three major sword styles, namely Sword God Style, Water God Style, and North God Style. I'll teach you all of them!" Roxy was also generous, and immediately took out paper and pen, writing as she walked.
The Fighting Spirit cultivation method and the three major sword styles were not secrets in the Jobless Reincarnation world, and were basically public, so everyone could learn them.
Of course, the three major sword styles circulating outside were all basic. The ultimate techniques were top secrets.
For example, Sword God Style, you can learn the basics, but the ultimate techniques of Sword God Style, "Soundless Sword", "Light Sword", and "Light Return", require you to go to the Sword Sacred Land and learn from the Sword God himself.
Roxy naturally did not have the ultimate techniques of the three major sword styles, but she did have the basic cultivation methods.
She felt that Saeko Busujima had high talent in swordsmanship and should be able to quickly learn the three major sword styles.
Although Lin Che was walking in front of the team, leading the way, with his current strength, he naturally heard Roxy's words.
He was actually very envious of the three major sword styles and Fighting Spirit method from the Jobless Reincarnation world.
He originally planned to ask Roxy for them after a while, but he didn't expect her to take them out herself.
Since that was the case, he also had to learn them.
He had Crested Martial Art, and any martial art or skill could be integrated into it, so the three major sword styles were naturally not a problem!
Roxy quickly finished writing the cultivation methods for the three major sword styles and Fighting Spirit.
She handed them to Saeko Busujima and said, "You can read them yourselves. Actually, I don't know anything about swordsmanship."
Saeko Busujima took it and read the three major sword styles carefully, and immediately revealed a look of ecstasy.
From this moment on, she found her path of cultivation!
Jiu Yu Wu Mi was a little disappointed, she used a bow and arrow and didn't practice swordsmanship.
However, fortunately, Fighting Spirit did not distinguish between weapons, it was simply a physical enhancement.
Because Roxy was live streaming, Hestia, who was watching at home, also learned about the three major sword styles and the Fighting Spirit method.
So she sent a private message to Lin Che.
Hestia: "A Che Jun, our Familia now has so many cultivation methods, should we integrate them and provide them to all Familia members for cultivation?"
Lin Che: "Yes, these cultivation methods are the foundation for the rise of our Familia, but they cannot be given to all Familia members for cultivation, only to the core members!"
God Familia members can change their allegiance. If they recruit more Familia members in the future, and they come into contact with these cultivation methods, and then leave the Familia and join other Familias, what should they do?
At that time, the secrets of the Hestia Familia would be exposed!
Hestia: "You are right, I will start organizing them now!"
Then she sent a message to Roxy, asking her for the cultivation methods of the three major sword styles and Fighting Spirit.
Next, she began writing in the basement of the church.
The magic of the Type-Moon World, the magic of the Fairy Tail world, and the magic of the Jobless Reincarnation world were all compiled into a book, named [Demonic Arts Codex]!
In the future, if there were new magic, they could continue to add to it.
Then, the three major sword styles and the Fighting Spirit method were all compiled into a book, named [Martial God Chapter]!
Lin Che wanted to give Hestia the hundreds of martial arts that Luo Hao taught him, but with Luo Hao's personality, if he taught the martial arts she taught him without her permission, something would definitely happen!
If the matter escalated, his sister-brother relationship with her would also come to an end.
However, he couldn't give out the martial arts, but Merlin and Artoria could.
One was a Britain Sword Saint, and the other was the legendary Arthur. Their Western martial arts could also be recorded in the [Martial God Chapter].
Lin Che told Hestia his idea, which made her eyes light up.
It was just that Merlin and the others were not Chat Group members and could not be contacted.
Hestia set her sights on the friends in the group and began to private message them one by one, trading for their martial arts and magic.
Finally, she traded for "Ninja Taijutsu" from Tsunade, "Requip Magic" from Erza, and "Balutasu Tribe Martial Arts" and "Empire Military Martial Arts" from Esdeath!
Then she compiled all these magic, taijutsu, and martial arts into the [Demonic Arts Codex] and [Martial God Chapter].
It was a pity that Luo Hao was unwilling to trade, otherwise, with her knowledge of martial arts, the [Martial God Chapter] could have been completely filled.
...
The sky gradually darkened. Lin Che and his group had spent a day and had already reached the twenty-fourth floor!
One more floor down was the Water Maze of the [New World].
Lin Che was not in a hurry to go down, but set up tents near the entrance of the next floor, planning to spend the night here.
There were a total of five tents. Lin Che, as the only male, enjoyed one tent by himself.
The remaining four tents were shared by the girls.
The tents were arranged in a circle, with the stronger ones staying on the outer ring and the weaker ones on the inside.
In addition, the stronger ones had to take turns keeping watch at night.
Merlin and Morgan took the first half of the night, while Artoria, Roxy, and Lin Che took the second half.
Five people, each taking turns on watch for two hours.
After the tent was set up, Lin Che took out ingredients and water from the Unlimited Blade Works space and handed them over to Sera and Lisellote to cook.
He himself went to find Roxy.
At this moment, Roxy was teaching Saeko Busujima and Jiu Yu Wu Mi the Fighting Spirit method.
Lin Che came over and also started to learn.
From Roxy's explanation, he quickly understood the cultivation method.
He sat cross-legged and began to control his Demon Power to wrap around his body, integrate into his flesh and blood, and strengthen his skills.
