Recognizing the difference in strength between herself and Lu Xiao, Tuoba Yu'er put away her competitiveness.

Since there is no direct conflict with Yuwen Tuo for the time being, she lacks a real sense of Yuwen Tuo's strength evaluation, but is more interested in the immortals in Lu Xiao's words.

"Is there really an immortal in this world?"

Lu Xiao nodded: "Yes, it's just that there is a spatial barrier between the place where they live and the Xuanyuan Realm where we are located, and they can't be reached through conventional means. ”

Tuoba Yuer has lived in the tribe of her hometown since she was a child, and everything she knows about the outside world stays in the stories told by her brother-in-law Zhang Lie.

Zhang Lie is not an idle person, he is a bearded guest among the rumored Three Heroes of Wind and Dust in the late Sui Dynasty and early Tang Dynasty, and he has a good relationship with Li Jing and Red Whisk Girl, who are also the Three Heroes of Wind and Dust.

In the chaotic times at the end of the Sui Dynasty, there were countless people who were interested in the world, and Zhang Lie was also one of them.

Over the years, he has been secretly recruiting troops and horses, and has gone to the Central Plains many times to recruit talents, and Li Jing and the Red Whisk Girl also met in this process.

Tuoba Yu'er's world used to be very small, and she thought that the tribe she lived in was the center of the world.

Stepping out of the familiar range of activities of the tribe, Yu'er knew for the first time that the world was so vast, and the martial arts she was proud of were nothing in the vast world.

Lu Xiao single-handedly caused a stir in Yang Guang's heavily defended fleet, and Tuoba Yu'er, who was determined to assassinate the Dog Emperor, wanted to learn infiltration techniques and martial arts from him.

But with a strong nature, she didn't know how to ask a stranger for advice for a while, so she could only deliberately attract Lu Xiao's attention in a clumsy way, and cheekily follow him to act together.

has experienced many worlds in a row, and Lu Xiao can be regarded as having read countless people, and he can see at a glance the true meaning hidden behind Tuoba Yuer's awkward way of self-presentation.

In the process of going downstream, Lu Xiao didn't mind instructing Tuoba Yu'er, at least teaching her the most basic latent skills, and providing some experience and advice on her knife skills.

The oriental martial arts that Lu Xiao initially learned were also knife techniques, and under the strict training of Skaha, Lu Xiao's use of various knife weapons had already been touched.

While the specifications of the knives differ, there is no decisive difference in usage.

"Your knife technique is a little too aggressive, the long-handled lancet is indeed a typical example of attacking instead of defending, but you must at least leave a little leeway for yourself to change your moves before making a move."

"And the big open and close moves don't fit your style perfectly, it's best to make some improvements according to the actual situation in actual combat."

After all, it was just a meeting in Pingshui, and Lu Xiao did not give in-depth guidance to Tuoba Yu'er, but only gave her point-to-point guidance in the direction of the progress of martial arts in the future.

Lu Xiao, who has the passive skill of Spiegel to stop water, has already gone ahead of most people in martial arts, if he is based on skills alone, Lu Xiao thinks that he will never lose to Yuwen Tuo.

But sometimes the crushing of power is so helpless, before obtaining a weapon equal to Xuanyuan Sword, Lu Xiao does not plan to provoke Yuwen Tuo again.

……

The metal bird that Lu Xiao handed over to Yongzhen contained part of his soul, which could establish a faint connection between the two.

This metal bird can not only find Lu Xiao's location on its own after being released, but Lu Xiao can also find Yongzhen's whereabouts in turn.

As Lu Xiao expected, during the transportation of Shending, someone suddenly released a false news, and the person who got Shending could win the world.

When he broke into the lower reaches of the Yellow River, Shending was robbed by a bandit known as the Demon King of the World.

When Lu Xiao took the boat all the way west, Yongzhen, who set off first, had already heard the relevant information about Shennongding, and traced it all the way to a poor village called Douzikeng.

The Demon King built by the Demon King of the Mixed World is located in the hill behind the bean pit, and compared to other loosely disciplined cottages, the thieves of the Demon King will not rob the poor people, but will only stare at the rich merchants and high-ranking officials to rob.

The villagers of Douzikeng have never been attacked by the Demon King, but have lived a barely peaceful life under the protection of this group of bandits.

Before parting, Lu Xiao made some disguise modifications to Yongzhen, making her appearance look more neutral, and it was difficult to distinguish men and women without careful observation.

After arriving at the bean pit, Yongzhen followed the advice given by Lu Xiao and came to the inn in the village to obtain information as soon as possible.

Taverns and inns are mixed places, and people from the nine streams of the triangle will first go to the inn to stay after entering the village, and then go to the first floor of the inn to drink and brag.

Yongzhen, who drank silently, pricked up his ears in the inn to listen to the conversations of the other guests.

Most of the conversations were just the neighborhoods of Zhang's family, Li Jiaxiao, but there was also some information related to the Demon King.

"It is said that the demon king of the mixed world on the mountain has recently made a big business, and he only returned triumphantly by beating gongs and drums a few days ago, and it seems that he has snatched something important from the hands of officers and soldiers."

"Whatever, it has nothing to do with us anyway, and Grandpa Demon King won't steal anything from the village, I hope he can stay in the mountains to protect us."

"Hi~ In this world, the officers and soldiers are like thieves, but the bandits protect the peace of the village, which really makes people laugh."

"Don't talk about it, drink and drink, anyway, I can't count on the emperor who spends all day drinking."

Yongzhen quietly picked up the bowl and took a sip of cold water.

'In the last years of the Sui Dynasty in the land of China, it really rose up as recorded in the history books. ’

'The demon king of the mixed world on the mountain should be the one who left a lot of ink in the history of the late Sui and early Tang dynasties, right? ’

The Japanese samurai class during the Warring States period had to learn Sinology from an early age, and the Tang Dynasty was the one they knew the most.

When the Tang Dynasty was strong, Japan sent a large number of envoys to the land of China, so that they could learn the advanced technology and knowledge of the Celestial Empire, and bring them back to their home country after being localized by local scholars, and transformed into their own things.

The most typical example is the Taidao that Yongzhen hangs around his waist, which was developed by Japan through the study and improvement of the Tang knife.

Over the years, Taidao has gradually become a symbol of Japan, but many people are unaware of the origin of Taitoji.

The standard weapons of the Tang Dynasty are almost in the same vein as the Sui Dynasty, and although the Yongzhen Taidao is slightly different from the popular horizontal knife of the Sui and Tang dynasties in terms of arc, it does not attract any unusual attention.

As the adopted daughter of pharmacist Daoxuan, Yongzhen has read a lot of sinology in addition to studying pharmacology since she was a child, and she also knows a lot about the history of the Sui and Tang dynasties.

Cheng Biting Jin, the demon king of the mixed world, this person often appears in various dramas, the most famous is his iconic three-plate axe.

Cheng Biting Jin is his real name, after the founding of the Tang Dynasty, the Demon King of the Mixed World began to adopt his heart, and changed his name to Cheng Zhijie, and was successively awarded the title of Su Guogong and Lu Guogong, one of the twenty-four heroes of Lingyan Pavilion.

"Demon King, let's go investigate overnight tonight, hoping to find a secret passage into the cottage." ’

……

After getting the necessary information, Yongzhen slipped out of the inn and into the back mountain of the bean pit that night.

The scale of the Demon King is not large, and Yongzhen took advantage of the night to carefully search near the cottage, but he never got any gains.

Even in the middle of the night, there were several energetic bandits standing in front of the cottage.

'The defense is so tight that it is impossible to sneak in from the main entrance. ’

Yongzhen didn't have the breath-blocking ability like Lu Xiao, so he could only give up entering through the main entrance and find another way.

'Huh? ’

On the way down the mountain road, Yongjin found a waterhole in the middle of the mountain.

Looking at the waterhole and thinking for a moment, Yongzhen dived into the water with a light movement, using the water system Guigu Dao technique to create a cavitation around his body that could store oxygen for a short time.

Sure enough. ’

Yongzhen just had the idea of giving it a try, but he didn't expect to really find a passage to the inside of the cottage underwater.

Coming ashore again through the waterway, Yongzhen found himself through the main entrance of the cottage and came to a small cave.

'The secret passage to the core area of the cottage? ’
