The system is the proficiency panel

Feng Tian and the three demon kings were a little worried about how to improve its strength.

Magical weapon? No, it can only improve strength to a limited extent. According to the current strength gap between Feng Tian and Lin Ji, it cannot make up for it.

They thought of several ways in succession but none of them worked. The gap between the first and second realms was too difficult to make up. Originally, Feng Tian had the ability to be reborn from the ashes and deal with the second realm, but Lin Ji could control the speed of time, which directly made them give up this idea. Feng Tian's strength was not as good as Lin Ji's, and because of his time ability, his speed was half as slow. If a fight really broke out, did the three demon kings doubt that Feng Tian could live for one second every time he was resurrected?

Looking at the expressions of the monsters, the ancient Wutong tree spoke.

"Give Feng Tian one tenth of my wood heart. This way, he will be able to comprehend the artistic conception of wood in a short period of time."

"Ancestor, Mu Xin is one of your origins, and the injury Mu Xin suffered last time has not yet fully recovered. How can you cut it again and give it to Feng Tian to use, and one tenth of it? I object!"

Hearing what the ancient Wutong tree said, Bluebird reacted strongly and immediately opposed this idea. Bluebird had been living on the crown of the ancient Wutong tree since the beginning of her cultivation. The ancient Wutong tree watched her cultivate from Qi training all the way to the Golden Core stage. The relationship between the two was like that of father and daughter. Bluebird could be said to be the princess of the Misty Forest, until Feng Tian appeared...

So when Qingniao found out that the ancient Wutong tree had used a small piece of wood heart to exchange for phoenix blood for Feng Tian to use, she was already very unhappy. Fortunately, Feng Tian worked hard and successfully built the foundation of his artistic conception soon after using the phoenix blood. Only then did she slowly let the matter go. She didn't expect that he would need the wood heart again now.

"Qingniao, calm down. Right now, the only thing that can quickly improve Fengtian's cultivation without side effects is my Mu Xin. And I can fully recover in a few decades, so don't worry."

The ancient Wutong tree explained to the bluebird in a gentle tone that as a bird, the bluebird's figure after transformation was very tall, and her body was wrapped in a layer of green feathers, which was very beautiful. Hearing the words of the ancient Wutong tree, she flew to the ancient tree unwillingly and continued to speak in a coquettish voice that did not match her age and body shape.

"Ancestor, one-tenth of Mu Xin! The last time I gave that person from Xuantian Sect, it was just a little bit. With Feng Tian's talent, even if he is not as good as that Lin Ji, he should not need so much! Even if you can give him something, give less."

Looking at Blue Bird's current appearance, the two demon kings did not have much reaction. They were much older than Blue Bird and had watched her grow up since she was a child. This kind of thing was not surprising to them. But Feng Tian was stunned. It was the first time he encountered such a situation.

"I have made up my mind. That's it. Let's go back and think about the terms of negotiation with Xuantian Sect."

After saying that, the ancient Wutong tree fell silent again. No matter what the blue bird said, it did not answer. She could only give Feng Tian a fierce look, then left and flew to the crown of the ancient Wutong tree.

"Feng Tian, ​​practice hard and don't let the old ancestor down."

Shanjun spoke rarely, then left with Xuanlin. Fengtian took one last look at the huge ancient phoenix tree in front of him and turned to leave.

……

Ten days later.

As the sky brightened, in the Xuantian City Lord's Mansion, Lin Ji, who had just finished training, called out the panel to check.

Lin Ji:

Cultivation: Foundation Building (Second Artistic Realm)

Skills: Time and Space (Space Movement: 25/100) Water (Purification: 70/100)

Power: Spacetime (spacetime domain, space tearing) Water (control)

Artistic conception: Sword (four kinds of power) Wood (three kinds of power)

'When I went to the Sword Sect, I was almost able to comprehend Water Power: Purification, and my proficiency in spatial movement increased at a good rate. I really don't know what it would feel like to comprehend the realm of time and space!'

Thinking of this, Lin Ji stood up and left the City Lord's Mansion, heading for Tianshu City. Six days ago, the equipment refining factory handed over the manufactured Trial Tower jade pendant to the Tianshu City array master, asking them to complete the final process of drawing a small array. According to the time Xiao Ningxue told him, it should be almost finished, so it was time to go and take a look.

In a high-rise wooden building in Tianshu City, a young female formation master placed the completed jade pendant in her hand into the jade box beside her. She stretched her waist to relieve her physical fatigue. She had been drawing formations for six consecutive days. Because most formation masters also had to study interstellar teleportation formations, they had to do this due to insufficient manpower. However, today it would finally be completed and she could be relieved.

At this time, a voice came from the front.

"Everyone, hand over your completed jade pendants. Daozi will come to pick them up today. Those who haven't finished yet, hurry up!"

The person who spoke was Hu Lingling, Xiao Ningxue's assistant. After all, it was impossible for Xiao Ningxue to personally handle the small matter of inspecting the jade pendant, so this task naturally fell on Hu Lingling.

Twenty jade boxes flew towards Hu Lingling in an orderly manner. According to the assigned task, each jade box contained fifty jade pendants. Hu Lingling scanned them with her mental power, and after confirming that there was no mistake in the number, she put the jade box into her storage ring and prepared to leave. At this time, the female formation master just now asked.

"Lingling, what is this jade pendant used for? It needs to be engraved with several soul detection formations."

Hu Lingling looked at the person who was speaking and found that it was Yao Yan, with whom she had always had a good relationship. After thinking for a while, she answered her.

"Sister Yao, I don't know either. The city lord didn't tell me. He just told me to collect them and bring them back. I won't talk any more. The city lord is still waiting for me! You can go and rest after completing the task. The spirit stones will be distributed to you all later."

After saying that, Hu Lingling slipped away, leaving more than 20 formation masters on the floor guessing what the jade pendant was used for.

When Hu Lingling arrived at the City Lord's Mansion, Lin Ji was already chatting and drinking tea with Xiao Ningxue, waiting for her arrival.

"Join Daozi, City Lord!"

"Lingling, where's the jade pendant?"

Xiao Ningxue stopped chatting and asked Hu Lingling, who immediately took out twenty jade boxes and suspended them in the air before speaking.

"I have checked, there are 1000 in total, please have a look, City Lord."

Xiao Ningxue checked all the jade boxes again and confirmed that they all had formations engraved on them. Then she asked Hu Lingling to leave and turned to Lin Ji who was drinking tea and said.

"Brother, when are you going to announce the existence of the Trial Tower?"

"I have asked You Ran to send a message to summon all the city lords to meet at Xuantian City in three days. I will then introduce the Trial Tower to them."

Lin Ji put down the teacup and replied, "This tea tastes good, better than the one from the Blood Demon Sect. I don't know what kind it is," Xiao Ningxue asked in some confusion.

"Brother, why don't you just start production? Send it out for testing like this."

"Just in case there are any loopholes, we need to test it. The test time will be until I return from Jianzong, which is about half a month. If there are no problems by then, we can start formal production."

Although he said he was testing, Lin Ji knew that half a month was too short and he would not be able to find any problems. He just hoped that he could try his luck and maybe find some loopholes.
