After feeding the cannons, Chen Yang enters the training room, takes out all the precious materials from Hei Xie Jiao, puts them on the ground, and analyzes them.

Claws can be used to refine shoes;

teeth can be used to refine stab weapons, such as cones and forks;

horns can be used to refine sword weapons after being dissolved;

whiskers can be used to refine whip weapons;

Chen Yang looked at it one by one and found that any part of the black dragon was enough to make a top-grade earthenware.

If taken together, even the next level of heaven utensils can be refined.

Of course, with Chen Yang's current experience in refining utensils, he is still reluctant to make utensils.

However, we can try to refine the best earth ware.

He put away all the other materials, leaving only the horns of the black dragon.

The black dragon has a huge body, and its horns are half a meter in diameter. Its body is black, smooth and glossy. It can even reflect the shadow of human beings.

It's a waste to use such a large material for refining utensils. Chen Yang only takes part of it, which is enough.

What's more, he plans to use the black lightsaber as the protoembryo and use the horns of the black dragon to upgrade the level of the black lightsaber.

Therefore, the consumption of materials should be less.

Of course, to refine the utensil, only the horns are not enough, and some other auxiliary materials are needed.

Chen Yang thinks about it, and he has finished the task of the task hall. He can just go to get the contribution points, and then exchange the materials he needs in the trading hall.

After thinking about this, he went out of the training room and called upstairs, "elder martial sister Yu, I'm going to get contribution points. Do you want to go with me?"

Yu Ziwen poked her head out of the stairs and said to Chen Yang, "although the task has been completed, she has helped the Li family to relieve the crisis. But I didn't contribute to this mission, and you saved my life. You can get the 1000 contribution points by yourself. "

Chen Yang shook his head and said, "it's no good. We're working together. Registration is also registered together. It's against the rules for me to collect contribution points by myself."

Yu Ziwen was silent. She waved her token and threw it out. She said, "you go to hand in the task. Just have my token. However, give me a symbolic contribution point, the other contribution points belong to you. "

With that, without waiting for Chen Yang to answer, the figure of Yu Ziwen disappeared from the stairway.

Chen Yang took the token and felt helpless.

He found that after returning from Fenglin island this time, Yu Ziwen's attitude to herself seemed even colder.

Women have such a situation, it must be because of emotional change.

Chen Yang was too lazy to think much. He left Tianzi No. 27 and went to the trading hall. He took a look at the refining materials he needed and calculated that he needed 436 contribution points in total.

"It's not too far off the mark. It's acceptable."

Chen Yang nodded and went to the task hall to hand in the task.

Seeing that he is holding Yu Ziwen's token, the disciple who is responsible for dividing the contribution points looks surprised. Yu Ziwen's token is handed to Chen Yang. It seems that she trusts Chen Yang very much.

Although he guessed about the relationship between Chen Yang and Yu Ziwen, the disciple didn't talk too much to avoid offending Chen Yang.

There are many disciples like him who stay in Yaoling branch.

They used to be formal disciples, but because of their general qualifications and old age, they should have left the Yaoling branch, but they volunteered to stay and do some miscellaneous work in exchange for cultivation resources.

These people, collectively known as the students in the courtyard, have a low status in the Yaoling branch.

In this case, of course, they do not want to offend Chen Yang and Yu Ziwen.

Chen Yang put two tokens on the table and said, "give me 436 contribution points, and give the rest to elder martial sister Yu."

There was a look of doubt in his eyes, but he didn't ask much and did it immediately.

Chen Yang took the token and went to the trading hall next door to change the refining materials. Then he returned to Tianzi No. 27.

"Sister fish."

According to the agreement with Yu Ziwen, Chen Yang can't go upstairs. He can only shout at the top of the stairs.

After a while, Yu Ziwen appeared.

Her face was flushed and she was sweating. It was obvious that she was practicing, and she was practicing to the key point.

"Your token."

Chen Yang throws the token. Yu Ziwen catches it and releases her true Qi. Her current number of contribution points appears on the token.

"2164."

After seeing it clearly, Yu Ziwen frowned and said to Chen Yang, "it's just a little bit. How can you give me 563 more contribution points?"

Chen Yang said with a smile: "you are a woman, of course I want to be humble."

"I don't need your humility."

Fish purple Wen coldly returned a sentence, turn round to go upstairs, way: "these contribution points, I will think of a way to return to you.". I don't like to owe people. "Chen Yang curled his lips and cried: "elder martial sister Yu, don't hurry. I want to ask why you are so cold. I don't seem to have provoked you."

Yu Ziwen's steps stopped and she didn't say much. Her figure disappeared at the corner of the stairs.

Chen Yang shook his head helplessly and turned to enter the training room.

Considering that the smelter might fail, he prepared a total of three materials for the smelter.

He took out the four elephant cauldron, put the horns of the black dragon in first, and released the purple hell inflammation, which was under the four elephant cauldron, and intended to dissolve some of the horns.

This step is beyond his expectation.

The black dragon's horns are very solid. It took three days to dissolve enough liquid.

Most of the remaining horns, Chen Yang income Najie.

Then he took out the other materials and began to mix them. He melted them together.

First melting, failure.

Chen Yang had been psychologically prepared, so he was not very disappointed.

However, the three days spent dissolving the horns of the black and evil Jiaos were wasted.

He spent another three days dissolving enough horns to begin fusing other materials.

This process took another two days.

This time, everything went well.

Then, he took out the black lightsaber, put it into the four elephant tripod, and fused the melted materials into the black lightsaber.

This stage is the most difficult to control.

Because the black lightsaber has long been formed, it is much more difficult to upgrade than to refine new weapons.

Chen Yang has feelings for the black lightsaber, otherwise, he would not choose to do so.

Fortunately, in the end, the black lightsaber was successfully refined.

In the four elephant tripod, there was a sharp momentum with a faint smell of black and evil Jiaos, which inspired Chen Yang's spirit.

"Good thing!"

He looked happy. Although he didn't see the black lightsaber, he decided that it was definitely beyond his expectation.

"Chen Yang, vice president is looking for you."

But before Chen Yang could carve runes for the black light sword, Yu Ziwen's voice sounded outside.

Strange. What's the vice president looking for?

Chen Yang is puzzled. He hasn't even seen the vice president of Yaoling branch. The other party suddenly looks for him. It's really strange.
