Shi Lang traveled for fifteen days, in the world of cultivators, time passed at the speed of light. Using the navigation from the satellite feed, his journey became simpler. On the way, he took time to send back a video message to his people in the caged realm.
He asked them to send some pictures and videos of themselves as he missed them. After Amelia passed away, he thought his heart was dead, but now that he has rediscovered his path, he knew that there was more to the world and human emotions than what he initially thought.
Closing his heart temporarily allowed him to grow stronger and grow around the pain that gnawed at him, but now that he was used to the pain, it was time for him to let others help him heal and stand back up to keep the last words of his wife.
Shi Lang traveled at a rather modest pace, unlike before, this time around he visited many small places. He wanted to try and see if he could comprehend something about the laws while observing the people. He spotted a few good seedlings but he decided to not intervene in their paths.
Firstly, he did not have the time to guide them. Secondly, this place was the territory of the seven families, he did not wish to get noticed. Although, he was travelling low key, if he got into trouble with the elders of any house then given how pompous the big family members were, it would escalate into a blood battle.
After half a month, Shi Lang arrived at the entrance of a magnificent city and found himself astounded. The walls of the city were made up of metallic substance which looked similar to cast iron. However, Shi Lang could sense spiritual energy coursing through the wall.
Lou Shin appeared next to him and said, "The spirit star iron walls, as astounding as ever."
Shi Lang asked, "What is this metal?"
Lou Shin replied to his questions, "Frontier City used to be the capital of an old dynasty, and it was called the Spirit Star City. The metal you see before you is actually a compound made with Spirit Star clay and the most common Star Iron. These walls are tens of thousands of years old."
Shi Lang was surprised, he did not expect these walls to have such a history behind them. He asked, "You said these walls are a compound, so does that mean we can create them as long as we have the necessary material?"
Lou Shin smiled and said, "If that was possible, we would have been able to have such walls around every town in the easter continent."
She thought Shi Lang was a bit naive to ask such a thing. She continued when he was left speechless, "The Spirit Star Clay is the base material of this compound and sadly, it does not exist in this plane anymore."
Shi Lang was shocked and Lou Shin said, "In there last stand against the ten thousand races, the army of the ruling dynasty marched wearing armors of the Spirit Star Iron, however, none of them came back. The spirit star iron is capable of blocking out space. So, the ten thousand races could never find their way in.
Shi Lang nodded to the explanation and asked, "Can I ask, why you are looking for me?"
Yang Harwing smiled and said, "You helped us take down that Void Barbarian Wolf. We have to pay you appropriately."
Shi Lang thought about it and nodded as he called them over to sit down. The little girl returned with two plates, and found four more guests. She was confused and Shi Lang said, "Get some for them as well kiddo. Tell me how much is it?"
The little girl replied, "Two silver coins."
Shi Lang was surprised and took out a small spirit stone, he said, "I do not have coins on me but only spirit stones. Do you accept them here?"
The little girl nodded and said, "Mortals cannot accept spirit stones, but they can convert them to coins within a days time to avoid deductions."
Shi Lang nodded and handed her the spirit stone. Yang Xiaoling watched the girl walk away and asked, "Daoist Shura, why did you stop in the mortal level of the city?"
Shi Lang shook his head but did not reply to her question, his comprehension was his own and he had no obligation to tell her anything. Lou Shin observed the two and said, "I am leaving, take care."
Shi Lang nodded and Yang Harwing asked after Lou Shin left, "Was that your Dao Companion?"
Shi Lang radiated a wave of killing intent at the mention of this, but he regained control quickly as he replied, "She is my elder sister."
Yang disciples were shocked by the sudden wave of killing intent but they calmed down quickly. Yang Xiaoling eased up the mood by talking and Shi Lang found out many things about the Frontier City. It turned out that the city was divided in two levels, one was for the mortals and the other was for the cultivators.
The cultivators resided in the core of the city as the spiritual energy was highly concentrated there, and that place was mainly occupied by the members of the seven families. The mortal level bustled with travelers who supported the income and household of the mortals.
In the upper realm, a body formation or a nascent soul cultivator was regarded as a mortal, because unless you have crossed the spirit sovereign realm, you could be killed as easy as killing an ant in this world.
