The system is the proficiency panel

Tieling City, a city in the Xuantian Empire, was named after its rich iron ore resources.

At this time, outside the city, in addition to the road that Lin Ji had ordered to be opened for mortals, a new road appeared at a higher position on the side. This road leading to Xuantian City was opened yesterday by a cultivator who had established his foundation in the realm of artistic conception. After the cultivator finished opening the road, he said goodbye to the Yang family and left, going back to report to Luo Youran.

"Taihua, is the ironworks almost finished?"

Yang Yong, standing on the city wall, looked at the road stretching out below and asked his grandson who had just come up behind him. Yang Taihua walked forward a few steps and said.

"It's almost done. It will probably be finished tomorrow. Then we can move the ironmaking equipment given to us by the refinery. The monks are building it too fast..."

Yang Taihua's tone was a little frustrated. Although he was born into a family of cultivators, he had no aptitude for cultivation and his family members seldom showed their strength in order to take care of his mentality. So he was not very clear about the strength of the cultivators. It was not until these few days when he had frequent contact with cultivators while building roads and factories that he realized how big the gap between mortals and cultivators was.

"Taihua, don't be so depressed. Although you don't have the aptitude to practice, you are very talented in learning those things from the star. Look, Lord Luo even supports you in developing steam locomotives."

"Grandpa, I understand the truth, but it will take some time to recover."

Hearing the sermon, Yang Taihua kicked the city wall impatiently, making Yang Yong shake his head helplessly.

"Taihua, let's go and see how the mortals we recruited are. These people will go to the ironworks in the future, so we have to select them carefully."

After saying this, Yang Yong was the first to walk down the city wall, and Yang Taihua hurriedly followed.

……

Misty forest.

After returning from the Trial Tower, Lin Ji continued to practice for a while. When the sun rose, he heard birds singing outside the house. He opened the window and looked outside. A white bird landed on the window, looked at him curiously for a few seconds, and then said.

"Master Daozi, these are the spiritual fruits that King Bluebird asked me to deliver. They are all in this storage bag."

Feiniao handed over the savings bag respectfully, and after Lin Ji took the savings bag and left, Lin Ji turned around and left the house and came to the yard. He found a place to sit down and began to enjoy the spiritual fruit. The taste of this spiritual fruit was excellent, even better than the ones cultivated by the Xuantian Empire.

After eating the spiritual fruit, Lin Ji looked at the quiet lake in front of him and the forest behind him. The trees were lush and green, and there was no end in sight. He got up and left, wanting to look around in the center of the misty forest.

Just as Lin Ji was leaving the lake area, the tall figure of the blue bird descended from the sky and landed behind Lin Ji. For some reason, she seemed to be in a good mood, with a smile on her face.

"Does Michiko want to take a walk in the Misty Forest?"

Hearing this, Lin Ji turned and looked at Qingniao and said.

"That's right. The center of the Misty Forest is a forbidden area for human cultivators. There aren't even many books describing it. It's normal for me to be a little curious. Does the Demon King want to stop me?"

For the sake of the shapeshifting technique, Blue Bird ignored Lin Ji's last words that made the demon unhappy, and still answered with a smile.

"Of course not, it's just that the Misty Forest is huge and it's easy to lose track of where you want to go without a guide. Why don't you come together and I'll lead the way?"

"Then I'll trouble you. I want to visit the territories of several demon kings."

Hearing Lin Ji's suggestion, Qingniao nodded.

"Of course, no problem. The closest Jindan demon king is called Xuanmu. His child Xuanlin once had a conflict with Daozi. I wonder if you still remember? Let's go."

After saying that, Qingniao led the way in front, and Lin Ji followed closely behind, all the way to the area where Xuanmu was. On the way, he discovered that Qingniao's personality was actually very cheerful, without any of the airs of a demon king, and chatting with him would not be boring.

Along the way, Lin Ji learned that the territory of the demon king Xuanmu was just to the north of this area. After slowing down for half an hour, Lin Ji saw the words "Beihai" engraved on a huge rock. The handwriting was a bit rough but it exuded an aura unique to Jindan. There was also a formation behind the huge rock, which made Lin Ji unable to know the scene behind it.

"North Sea? If the map is correct, this place is still some distance from the sea."

Seeing the name engraved on the boulder, Lin Ji couldn't help but stop and ask in confusion.

"You'll know when you get in."

Without further explanation, Qingniao turned and walked towards the direction of the North Sea. Lin Ji could only follow. After entering the formation, his vision suddenly became wider. In front of Lin Ji was a coastline with a width of about 100 meters. In the distance were endless blue waves and some islands.

"This was originally a forest. More than a hundred years ago, when I was not yet a golden elixir, Xuanmu said that since I had the appearance of a black tortoise, of course I had to live by the sea. I asked the ancestor for permission to open the sea. After frequent harassment, he got his wish. With one punch, he punched from here to the Endless Sea, through one seventh of the East Continent, and led the sea water into the Misty Forest. After a hundred years, it became what it is now."

Bluebird explained while looking at the sea in the distance. At this time, Lin Ji noticed a black dot appearing in the distance, and then a strong man came in front of the two of them. When he stopped, the North Sea behind them reacted and split into two halves in the middle, forming two huge waves that hit both sides.

"Bluebird, how come you have time to come to Beihai? Don't you usually stay at home? Um, is this person next to you... a Taoist from Xuantian Sect?"

The burly man first greeted Bluebird, then looked at Lin Ji and asked tentatively.

"That's right. Daozi's name is Lin Ji. I'll show him around the Misty Forest. Xuanmu, how about we visit you now?"

Qingniao pointed to Lin Ji standing aside and introduced him, then paid attention to Xuanmu Cave. Xuanmu stayed at the bottom of the sea all year round and often left the Misty Forest to go to the Endless Sea to practice and search for treasures. There must be good things there. If he asked for a few things from here, the ancestor would give Lin Ji less at that time.

"Of course, Michiko, this way please."

Hearing Qingniao's cunning words, Xuanmu, who had watched her grow up, knew that she was thinking of something bad, but Xuanmu still agreed immediately. After all, the demon clan would become a vassal in the future, and he would definitely not be as free as he is now. He would need to obey Lin Ji, so it would be good to build a good relationship first.

The three of them walked on the waves and headed towards the largest island in the sea. Xuan Mu introduced the things about the North Sea to Lin Ji as they walked.

As they got farther and farther away from the land, the number of monsters in the sea increased sharply, but they were basically all practicing Qi cultivation. Among them, the most numerous were turtle monsters. They sensed the breath of the Demon King and did not dare to come over to disturb them, so they all watched from a distance.

Soon the three of them arrived at an island. The island covered a large area and was shrouded in a layer of light blue mist. This mist was not an ordinary mist, but was condensed from spiritual energy, which was very beneficial for cultivation. This was Xuanmu's cave.

"Daozi, the place above the island is where I usually entertain guests. It has a beautiful environment. The seabed below is where I usually practice and live. Daozi, which one do you want to see?"

Xuanmu pointed at the island and introduced it. From his tone, it seemed that he wanted to go to the island to take a look. Lin Ji was just about to follow his wish when the blue bird next to him suddenly kicked the sea surface with its bare feet, splashing waves, and then spoke as if nothing had happened.

"Look at what I'm doing, Michiko, you choose!"

"Xuan Yao King, let's go to the place where you practice. I'm sure the spiritual energy there must be more abundant than on the island."

Lin Ji said with a smile, and Xuan Mu naturally agreed, but he still glared at Qingniao without leaving a trace, and then the three of them dived into the sea.
