The system is the proficiency panel

At noon, in the City Lord's Mansion of Xuantian City, an old man and a young man were waiting outside for Luo Youran's summons. From the expression on his face, it could be seen that the old man was very reluctant.

"Taihua, do you really have to make that steamed dish?"

"Grandpa, it's a steam locomotive."

Yang Taihua spoke up helplessly and corrected the old man's mistake, but this attitude made the old man even more unhappy.

"So why did you get that thing? Although you don't have the talent for cultivation and can't become a cultivator, it's very simple for our Yang family to guarantee you a lifetime of wealth and glory. I wouldn't have let you go to any school. After more than ten years of study, you have learned to talk back to your grandfather, and now you still want to..."

Just as the old man was chattering on and on, a maid in the Qi training stage came out from the City Lord's Mansion, saluted to the old man and said.

"Uncle Yang, the city lord agrees to see you. Go in now."

"it is good."

Led by the maid, they passed the front hall, entered the City Lord's Mansion, and stopped at a quiet palace. From inside, they heard Luo Youran's clear and pleasant voice.

"come in."

The two old men quickened their pace and entered.

At this moment, Luo Youran was sitting in front of an imperial desk looking at the design drawing in her hand. She was wearing a light blue long dress, with her black hair draped over her shoulders. Her face was delicate and refined, her skin was as white and smooth as snow, there was a sense of nobility between her eyebrows, and her big watery eyes sparkled with wisdom. Her simple and elegant dress made her look even more beautiful and elegant.

"See the City Lord."

The two men bowed in unison, their voices extremely respectful, showing their humility.

"Well, get up."

Luo Youran raised his eyes and glanced at the two of them, then lowered his head and continued to look through the design drawings in his hand.

"Yang Yong, did you design this steam locomotive? Tell me how far you can go."

"To the city lord, this was designed by my grandson Yang Taihua. I can provide some advice, or he can make the decision himself."

The old man Yang Yong pointed at Yang Taihua and began to explain, then turned the topic to Yang Taihua.

"City Lord."

Yang Taihua bowed respectfully to Luo Youran, and then began to explain his ideas.

"The steam locomotive is made up of a huge steam-powered furnace. Originally, the furnace was going to use wood and coal as fuel, but after my grandfather's improvement, it can directly absorb the spiritual energy between heaven and earth as fuel, generate high temperature to make water evaporate and expand to generate power, and then use levers, pistons and other things to make the train move. The speed can reach at least 100 kilometers per hour."

"This is what I and several classmates who graduated from school learned about the principles of steam engines and imitated the steam locomotives on the Blue Water Planet. It has no effect on monks, but it can greatly facilitate the travel and transportation of mortals. I hope to get the support of the city lord."

After listening to Yang Taihua's explanation, Luo Youran put down the drawings in his hand and nodded.

"I'll think about it, you guys go down."

"Yes, City Lord."

Yang Yong and the other man responded and turned to leave.

After Luo Youran looked at the design drawing again, he took out a piece of paper and began to plan the future implementation of the steam engine. For example, he needed to build some ironworks and give mortals something to do. It was impossible for the monks to complete it all. There would not be enough time. Moreover, he also had to arrange for the monks to reopen the road for the trains to run.

……

Tianshu City.

"Ningxue is in seclusion practicing?"

Lin Ji asked Hu Lingling in surprise, and after getting her confirmation, he decided to leave first and not disturb Xiao Ningxue's practice.

"If Ningxue comes out of confinement, remember to ask her to find me."

Hu Lingling nodded, and Lin Ji turned and left to go to Luo Youran.

After leaving, Lin Ji patrolled over the sky above Xuantian City. Xuantian City has changed a lot compared to before. Now it is the center of the East Continent. The outer city has expanded several times. The roads are wide and a large number of mortals live here. Merchants gather here to sell supplies. The school seems a bit empty because it is too large. The inner city has not changed much. After all, there are not many cultivators. Seeing such a prosperous scene, Lin Ji was quite satisfied.

Arriving at the City Lord's Mansion, Lin Ji went straight into the palace where Luo Youran was. At first sight, he saw the dignified and elegant girl sitting in the center of the palace.

The sudden sound of footsteps in the palace caught Luo Youran's attention. He looked up at the door and saw Lin Ji slowly walking towards him.

"Master, you are back from the Sword Sect!"

After seeing Lin Ji, Luo Youran's eyes lit up, and she stood up and looked at him with a smile on her face.

"Well, I gained a lot from this trip. I am in the third state of mind."

He walked over to Luo Youran and sat down beside her, then picked her up and placed her on his lap, looking at the beauty in his arms with an attitude of enjoyment.

"Three artistic conceptions, congratulations, Master!"

Luo Youran happily hugged Lin Ji's neck and kissed her on the lips. After they were intimate for a while, Lin Ji took out the savings rings he brought from the World of Beasts and placed them on the table. Under Luo Youran's curious gaze, he chose two and handed them to her.

"These are all wood-attributed cultivation resources. They should allow you to condense the wood realm within 20 years."

"Give the remaining rings to the Equipment Refining Factory, the Alchemy Palace, and Tianshu City respectively, and let them study them on their own. Also, write back to Misty Forest and tell them that I will visit you in three days."

"Master, are you going alone? It's too dangerous."

Seeing that Lin Ji seemed to be going alone, Luo Youran said with some concern, after all, the Misty Forest is the territory of the demon clan.

Lin Ji smiled, gently stroked Luo Youran's fair and delicate skin, and spoke softly.

"Don't worry, it's okay."

Seeing Lin Ji's determination, Luo Youran stopped trying to persuade him and nodded. Then she briefly told Lin Ji what had happened in the past few days. Then Lin Ji left and went back to his room to study the space crystal.

......

The three days passed quickly and arrived in the blink of an eye. On this day, Lin Ji got up early, practiced sword for a while, said goodbye to Luo Youran, and went directly to the Misty Forest.

During these three days, the managers of the Equipment Refining Factory and the Alchemy Palace all came to thank Lin Ji for the things he had sent, especially Ye Hui, the Palace Master of the Alchemy Palace, who gave him a special pill as a token of his gratitude. After all, many of the spiritual plants that Lin Ji brought back were not found on Kaiyang Star and were priceless treasures, so Ye Hui transplanted these spiritual plants personally to ensure that there were no mistakes.

As for Tianshu City, Xiao Ningxue was still in seclusion, and no one else dared to overstep her authority. In addition, the relationship between Lin Ji and Xiao Ningxue was known to all the cultivators in the entire Xuantian Empire, so no one was sent to see Lin Ji.

After studying the space crystal for a while, Lin Ji discovered that he could indeed replenish the energy inside, but the speed was too slow. It would take at least 5 years to fully replenish it without interfering with his cultivation, so he could only do it slowly.

Lin Ji arrived above the misty forest without any obstruction. At this time, a figure approached quickly from a distance. It was Feng Tian. When it saw Lin Ji, it was stunned for a moment, and then spoke. Although it was a male, its voice was indeed the most pleasant Lin Ji had ever heard.

"Lin Ji, come with me, the ancestor has been waiting for a long time."

Hearing this, Lin Ji did not hesitate, nodded in agreement, followed Feng Tian's footsteps, and flew away into the distance.

More than ten seconds later, Lin Ji entered the central area of ​​the misty forest under the guidance of Feng Tian. The first thing he saw was the huge ancient phoenix tree. The ancient phoenix tree was towering and towering, with luxuriant branches and leaves, and its roots were rooted in the ground, covering half of the sky. It stood like a huge mountain, surrounded by many small ancient trees, and looked quite spectacular.

Feng Tian flew to the ancient tree first, landed on the ground and bowed respectfully to the ancient tree. It was really strange for a bird's body that had not yet transformed to do this. Then Feng Tian spoke to the ancient Wutong tree in front of him.

"Ancestor, Xuantian Sect's Taoist Lin Ji has arrived."

As soon as he finished speaking, the branches of the ancient Wutong tree began to shake gently, the crown of the tree swayed, and a breeze blew out from it, blowing Lin Ji's clothes fluttering and his hair dancing. He felt a powerful pressure coming towards him, making him feel breathless. As expected of him, he was the second strongest man in the East Continent. This should be the reason why he restrained himself.

"Feng Tian, ​​you go down, Lin Ji just stays here."

Then, an old voice sounded, and Feng Tian quickly responded when he heard the voice.

"Yes."

Then Feng Tian flew towards the crown of the ancient Wutong tree and disappeared from Lin Ji's field of vision in the blink of an eye. Facing the ancient Wutong tree alone, to be honest, he felt a little pressured, but that was all, and he didn't show any fear or anything.

"I wonder what the senior wants to talk to me about?"

Lin Ji looked at the ancient sycamore tree in front of him and asked in a humble manner.
