After Chu He really took out four hundred high-grade spirit stones, the young lady who had a good identity at a glance suddenly had nothing to say.

In fact, she didn't want to let go of Tianxin Fruit like this, especially since it took her a while to cut the price from five hundred to four hundred, if this person really didn't return it, wouldn't she be bargaining for others for nothing?

But after all, this was what she promised herself, no matter how reluctant she was, she could only watch Chu He take the Tianxin Fruit away.

As for Chu He, although he didn't find anything good during the trip to Fang City, and he pressed out four hundred high-grade spirit stones for nothing, he was still quite satisfied with the overall result.

Knowing that there would be a trade fair at the end of the month, he could go over and see if he could come across some good materials, and he also got an interesting lock box, which he just took back to study well.

You must know that Chu He's Nine Turns Heart Demon Sword also contains extremely powerful Tianxin Fruit energy, but it was forcibly refined into Lang Huan's Heart Sword by Chu He at the beginning, and it was completely sealed.

And today, some of this power is used to integrate the demons into the sword, but some of it is still in the sword.

Chu He had tried to derive this part of the power, but unfortunately the power of the Heavenly Heart Fruit was too domineering, even if it had been refined into the sword, it was not something that Chu He could control, and as soon as it was drawn out, it would be the result of a complete explosion.

If he can study the principle of this spirit locking box, maybe Chu He will be able to control this power, and he will be able to have one more killer feature.

While thinking about these things in his mind, Chu He quickly returned to the inn, and Cao Jie was still practicing hard, repeating the practice of the mental method over and over again, trying to make the body remember the route of this true qi.

After encouraging Cao Jie a few words, Chu He went straight back to his room and began to study the lock spirit box.

"What is the principle of the locking spirit box to block the spiritual energy? The first thing to determine is whether this box blocks all the flow of spiritual energy inside and outside, or whether it is a container designed only for the Heavenly Heart Fruit. ”

Chu He quickly found a breakthrough in the study of the lock spirit box, and then followed this line of thought. It's not the first time he's sat down for this kind of thing, in fact, Yao Ji often finds similar jobs for him to do.

I have to say that Yao Ji is indeed a very good teacher. When she found that Chu He's momentum and understanding were not high, but her thinking was extremely rigorous, she changed the way she taught.

She began to teach Chu He the principles of Dao techniques, and then found some strange Dao techniques, or gadgets composed of strange Dao techniques, for Chu He to study, so that Chu He could decipher the principles of their composition.

In this process, Chu He inevitably came into contact with all aspects of knowledge, including alchemy, refining, formations, talismans, etc., and Yao Ji was able to answer them one by one, which shows the breadth of his knowledge field.

After several years of cultivation by Yao Ji, Chu He's cultivation literacy has been very high, and his level of seeing problems and understanding the essence of cultivation even surpasses some Jindan real people.

In all aspects derived from cultivation, Chu He has also dabbled in most of them, but the level is far from reaching the level of becoming a teacher.

Among these knowledges, Chu He was most interested in the formation and refining weapons. Because the cooperation of these two is the basis for most of the magic weapons and props in this world.

The same is true of the lock spirit box in front of Chu He now, the production of this box can be said to be rough, Chu He concluded that this should be something made by someone casually, and it is definitely not the work of a professional refiner.

"It's possible that the stall owner, Xiong Daoren, did it himself. Chu He can imagine such a scene: after Xiong Daoren found a Tianxin fruit, he didn't dare to pick it because he had no way to preserve it, so he had to make a temporary container and come out.

But on second thought, something is wrong. If this is the case, Xiong Daoren can make another lock spirit box, and Chu He and the young lady don't have to be so entangled.

In this way, the container should have been prepared.

But after a closer inspection, Chu He found that this box was indeed exclusive to Tianxin Fruit, and it was specially made for Tianxin Fruit. Its effect was only to isolate the overflow of the power of the Heavenly Heart Fruit, but it could not isolate other aura.

What's going on? With such a highly targeted container, it is impossible for Xiong Dao people to prepare it before discovering the Heavenly Heart Fruit, right?

Could it be that after Xiong Daoren found the Tianxin Fruit, he specially went back to find this container?

The possibility of such a situation is really small...... Chu He just briefly checked the lock spirit box for a while, and many questions arose in his heart. However, he could not find answers to these questions, so he had to continue researching.

Unbeknownst to him, there was an invisible net in front of him, and his hand was about to touch it.

In a place where Chu He couldn't see, Xiong Daoren put away the things on the stall and slowly walked out of the market. After making sure that no one was following, he cautiously walked into an alley, and his figure completely disappeared into the shadows.

There's already a man in black waiting for him.

"How is it? Did Tianxin Fruit and the box get in Miss Gongsun's hands?" As soon as the man in black saw Xiong Daoren, he couldn't wait to speak.

Xiong Daoren shook his head with a pale face, and said hatefully: "No." Before Miss Gongsun appeared, someone recognized the Tianxin Fruit, and he wanted to buy the box, and I suspect he saw something. ”

"This can't be!" exclaimed the man in black, "That box was handmade by Master Lin himself, although it was only a rush product, but the quality was absolutely passable." Even Master Lin himself said that it takes a good study to see the trickiness in it, how can anyone see the problem at a glance?"

Xiong Daoren kept his face calm and did not speak, and the man in black had to ask what the result was.

"After I sold the Tianxin Fruit to Miss Gongsun, I was afraid that the person would find Miss Gongsun in private and they would see the flaws together, so I pretended that the box had been sold to someone else, and specially waited for him to come, who knew the result would be ......"

"The result?"

As a result, the man took out four hundred spirit stones and mortgaged the Heavenly Heart Fruit into his own hands. Xiong Daoren said with a look of annoyance.

"This ......" The man in black couldn't speak, he couldn't figure out how the plan that had been arranged above could have become like this, "Who is that person?

Xiong Daoren was startled, and hurriedly stopped him and said, "No! Absolutely not! You kill him now, who will return the Tianxin Fruit and the box to Miss Gongsun?"

"But what if he really sees the flaw?" the man in black asked rhetorically, leaving Xiong Daoren speechless.

The two were silent for a long time, and Xiong Daoren suddenly said: "I remember, that person came in with a little boy from the Tokuma Gym, it is likely that he is a monk from other places, temporarily residing in the Tokuma Gym, we might as well start from there......"
