Creed of the heavens

Undying Slash is a Japanese sword with more than enough sharpness but low strength.

After obtaining the Divine Weapon Xuanyuan Sword, Lu Xiao positioned the Immortal Slash, which has a special attack effect on dragons and undead creatures, as a functional weapon, and its frequency of use will inevitably decrease in the future.

After completing the two world missions, the system left Lu Xiao with plenty of time, with a one-year return buffer.

After saying goodbye to Chen Jingchou and Yu Xiaoxue who were about to go south, Lu Xiao and Yongzhen headed north all the way. They planned to check on Yu'er before leaving.

Dayanling, the former residence of the Tuoba tribe.

After 10 years of turmoil at the end of the Sui Dynasty, Dayanling had long been deserted, and the nomadic Tuoba tribe headed north to escape the war under the leadership of Yue'er.

However, grassland peoples such as Tiele and Turks were also unstable, and there were endless internal struggles. The Tuoba tribe could only struggle to survive among the big tribes.

When Zhang Lie and Yue'er found the Tuoba tribe in the depths of the grassland, Yue'er was almost unable to hold on, and could only barely keep the tribe from being annexed.

There are very few Xianbei people who still belong to the Tuoba tribe, and almost everyone has a different heart.

In 626 AD, that is, last year, Li Shimin, who was called Tian Khan by the grassland people, was forced to make a bridge alliance with Jieli Khan in Weishui, which is the famous Weishui alliance in history.

At this time, the Turks were powerful, and Datang, who had not yet sorted out his internal affairs, decided to hide his strength and bide his time.

Li Shimin deeply remembered the shame of the Weishui Alliance, and made up his mind to return this shame to Jieli Khan in the future.

The invincible Turks became more and more domineering on the grassland, and countless small tribes were annexed by the Jieli Khan tribe, and the Tuoba tribe was just one of them.

When Zhang Lie, who had been away for ten years, rushed back to the tribe, the Tuoba tribe had accumulated so much that it was hard to return, and even Zhang Lie could not reunite the people who had their own ghosts.

Zhang Lie, who had lost his ideal of fighting for the world, didn't want to pay any attention to these ungrateful Tuoba clansmen. After handing over the power of the patriarch, he took the Tuoba sisters and drifted away.

When Lu Xiao and Yongzhen were looking for the early Tuoba tribe, they happened to meet three people who were about to leave after finishing their chores, and learned from them what happened to the Tuoba tribe in the past ten years.

After all, she was born and raised her own tribe, and the soft-spoken Yue'er is not as free and easy as her sassy younger sister.

She looked very depressed, thinking that she had failed Zhang Lie's expectations and failed to manage the tribe well during the time when Zhang Lie was busy saving the land of China.

Zhang Lie tried every means to comfort Yue'er but couldn't heal the sadness and guilt in Yue'er's heart in a short time. He decided to travel around the world with his wife and put all these unhappy things aside.

The brother-in-law intends to live a two-person world with his sister, and it is naturally inconvenient for Yuer, who has grown up, to follow behind them as an oil bottle.

Just when Lu Xiao and Yongzhen came to check on the situation, Yu'er bid farewell to her sister and brother-in-law.

Yu'er has a bright and cheerful personality, and she had a bad habit of being impulsive earlier. After being polished by Lu Xiao and Yongzhen, the unnecessary edges and corners in her character have been smoothed out a lot.

When taking Yu'er all the way south to the Western Regions, Lu Xiao asked her about her next plan.

"Yongzhen and I are scheduled to travel far away within a year, and we probably won't return to the Central Plains in the future. What are your plans?"

"Um"

Yu'er thought about it for a while: "The turbulent grassland is not suitable for staying for the time being. I plan to travel in the Western Regions first."

Yu'er spread her hands mockingly: "My temper is a bit incompatible with the reserved Central Plains people. Perhaps it is the best choice to stay in the Western Regions for activities."

"Alright."

Lu Xiao rubbed Yu'er's hair encouragingly: "The Western Regions have completely different customs and customs from the Central Plains. Perhaps here, you can carry forward the ideas I passed on to you."

The Western Regions first generally referred to the vast land west of Yumen Pass and Yangguan. In the Sui and Tang Dynasties, the concept of the Western Regions was further expanded. When Tang Xuanzong Li Longji was in power, a complete military government system such as Beiting Dufu and Anxi Duhu was established.

In modern terms, the Western Regions are my country's Xinjiang Autonomous Region and Central Asia. There are a large number of small countries in this area, and it is an important area that the Silk Road passes through.

Going west through the Western Regions is the Arab Empire with strong military strength. China calls it the Great Food Kingdom and the birthplace of the Assassin Order.

Lu Xiao doesn't know how Yu'er will develop in the future. If she really develops the Assassin organization in the Western Regions, it may in turn affect the Dashi Kingdom, and in disguise, the Assassin organization will use a different style in this world. Way to rise.

It seems interesting to think about it carefully, but Lu Xiao is not sure whether Yu'er can finally achieve his vision.

Calculated according to the time in the human world, Yu'er is 27 years old this year, but her mental age is still at 17, and she still needs a lot of practice and experience.

Lu Xiao, who was worried about her apprenticeship, spent the rest of the year on Yu'er.

Climbing, assassination, free running, underwater breathing, archery, close combat, Lu Xiao taught Yu'er all the assassin skills she had mastered without reservation.

The competitive Yu'er absorbed the knowledge and skills taught by Lu Xiao like a sponge, and Yong Zhen also taught her some knowledge about identifying drugs in her spare time.

Pharmacology is extensive and profound, and it is impossible for Yu'er to learn everything in just one year.

Yongzhen just told her the characteristics of some healing medicines, so that Yu'er can collect medicines for treatment after being injured in the wild.

In Shiguo of the Western Regions, Lu Xiao saw a satisfied smile on Lu Xiao's face as she witnessed Yu'er silently sneaking into the mansion and executing a small local official in Yurou Township.

"It's time to leave."

Yu'er returned smoothly without causing any commotion, and was greeted by Lu Xiao and Yongzhen's encouragement and praise, as well as farewell.

Pointing Yu'er's forehead with her finger, Lu Xiao smiled and said to Yu'er who was showing reluctance: "You have already graduated as a teacher, and you don't need a mentor to guide you all the time."

"Keep in mind the philosophy of the Assassin Organization. If one day I hear that you have deviated from the purpose of the organization, I will come back from afar and take everything from you with my own hands."

Yu'er nodded solemnly and said: "Everything is false, and everything is allowed."

"We serve the light and work in the dark."

"We are assassins."

Chapter 420 System leak

After finishing their experience in the world of Scar of Sky, Lu Xiao and Yongzhen returned to the main world.

"call"

In the mission world, Lu Xiao never dared to relax his vigilance. As soon as he returned to the tranquil and peaceful main world, he immediately let go of the tense nerves all over his body.

"Welcome back, two, is the trip going well?"

Aletheia issued a synthesized voice through the computer speakers, greeting Lu Xiao and Yong Zhen who had just returned.

"Fortunately."

Lu Xiao sat up from the bed and stretched her neck: "It's the first time I entered the oriental magic world. I'm not used to it, but I finally completed the task smoothly."

"By the way, where is your body?"

Lu Xiao looked at Aletheia who appeared on the computer screen in doubt: "Would it be possible to check the information again?"

"of course not."

Aletheia pointed down: "I'm still debugging equipment in the underground laboratory, and it's only been a second since you left. Where do you think I can go?"
