After solving this hidden danger in his heart, Lin Quan, who was in a relaxed mood, also became idle for a while. After meditating for a while, he suddenly remembered that he hadn't taken good care of the Tai Chi space for a long time. It was rare to be in a good mood, and Lin Quan followed his heart and directly entered the Tai Chi space.

..................

With the continuous improvement of his cultivation, the Tai Chi space is also constantly changing.

Now the size of the entire space has reached a radius of 100 zhang. Although Lin Quan couldn't calculate the height of the space accurately, according to his judgment, based on his previous experience, it should have reached the number of fifty zhang. After the space was larger, there were more cultivation of various spirit grasses, spirit valleys, and spirit trees. In addition, the fish and shrimp in the four large ponds and some small animals that he specially stocked form a paradise full of life and vitality.

The only thing that made him not very satisfied was that the "Yin Yang Tower" in the middle of the space did not become a corresponding height of ten zhang after reaching a height of nine zhang as his cultivation broke through to the tenth floor. This made him disappointed and a little conjectural.

The height of the tower remains the same, and the size of the tower naturally does not change. In this way, it also means that the size of the black soil where spiritual grass can be planted in the tower is also only nine zhang square. Originally, he had always thought that this magical "Yin-Yang Tower" would also grow like the Tai Chi space with the improvement of his cultivation. This result made him sullen for a while after successfully breaking through to the tenth layer of condensation.

Eventually, though, he saw it. Manpower is sometimes poor! Sacred objects such as Tai Chi Space and Yin-Yang Pagoda are inherently hard to find. Being able to get it by yourself is already a great opportunity, how can you still ask for too much? What's more, the path of cultivating immortals is originally to cultivate the mind and body, and external objects are external objects after all. If we blindly rely on and rely on external things, we will eventually go astray.

After understanding this truth, Lin Quan's state of mind has been further improved. The Dao Heart has also become more stable.

With nothing to do, he first took a turn in the "Yin-Yang Tower". Then it took some mental power to sort out all the items that were a little messy in the entire space. Just as he was about to leave, a black jade box covered in mystical patterns in the corner caught his eye.

"Hey, this is ......" Lin Quan's heart moved, and he casually sucked it into his palm.

At first glance, the black jade box looks very ordinary, and it is easy for uninformed people to regard it as an ordinary worldly object. However, Lin Quan immediately remembered that this jade box was the "Unmysterious Box" passed down by Du Hongbot.

"Uncle Du, it's been more than seven years since Tiannan was separated. Where are you now, and are you well?"

Reaching out and gently stroking the cold jade box, Lin Quan fell into a short period of deep thought, and his eyes revealed a strong sense of longing.

"Master, no matter where you are now, the disciple will definitely try his best to find you. Even if it's just in case...... I will do my best to complete what you have to say. After the consciousness returned to the body, Lin Quan secretly made up his mind with the "Unmysterious Box" in his hand.

Since there was a Tai Chi space, Lin Quan has always collected the "Unmysterious Machine Box" in order to take good care of this thing. Now when he saw this thing again, he realized that he had unconsciously reached the conditions for opening this casing. Therefore, he can't wait to open it.

He had already guessed that what Du Hongbo was going to do when he left the Su family alone must be related to Weixuan's lineage, and if he wanted to understand the ins and outs of the whole thing, he could only find the answer by opening the receiver and taking out the things that Du Hongbo wanted to hand over to him.

There are two major difficulties in opening the "Unmysterious Box". The first is, of course, that you must use your own wood and earth spiritual power to crack the array lock on the receiver one by one according to the essentials of the Unxuan Array Dao Technique. The second is that after successfully cracking the formation, it is necessary to use the unique technique of the unmysterious mechanism to open a hidden lock. The two complement each other and are indispensable.

After studying this receiver over and over again for more than two hours, Lin Quan finally figured out the array lock and mechanism lock on it. After knowing this, he carefully began to crack it.

After a short while, he completely cracked the two hidden locks on the receiver. Next, after taking a deep breath, he flexibly moved the ten fingers of both hands on both sides of the receiver at the same time, only to hear a soft "click". The receiver finally opened.

After successfully opening the casing, Lin Quan did not rush to inspect the treasures inside, but instead held up the jade box with great interest and studied it. He wondered why this "Unmystified Box" could become the inheritance of the Unmystified Lineage, and once locked, it would be so difficult to open.

"Oh, that's so clever with the double lock on this receiver. It's no wonder that Uncle Du and their pulse have declined, and no one has been able to successfully open this casing for so many years. If I don't have the ability to use both of my heart, I'm afraid that my cultivation will not reach the condensation period, and I can only sigh with joy. ”

It took Lin Quan more than half an hour to roughly figure out the wonder of this unmysterious box. To put it simply, this casing is mainly based on the particularity of the material to make two interrelated "locks" with one spirit and one custom. The first "lock" is naturally a formation lock that requires the use of spiritual power to crack, and the second "lock" is a mechanism lock that requires the use of specific techniques. If you want to open these two different locks at the same time, you must cultivate both the Array Dao Technique and the Mechanism Technique, and your own cultivation must not be too weak. Then, if you just do this, you have to use the dual-purpose talent to press both locks at the same time to finally get your wish. Otherwise, the entire receiver and the treasures stored inside will self-destruct.

With so many restrictions, Du Hongbo, who had long since declined, naturally no longer had the ability to open this casing. What's more, the last step also requires the use of dual-purpose talents. This also explains why Du Hongbo has been looking for a disciple with a dual-purpose talent. ]

After fiddling with the "Unmysterious Receiver", Lin Quan focused on the items in the receiver.

There is not much space in the receiver, and there are two items in total. The first is a quaint gray-black bracelet, and the other is a small white storage bag.

After a little discernment, Lin Quan understood that the small storage bag was left by Du Hongbo, and the gray-black bracelet with a simple style should be a treasure left by the elders before the Xuan Dynasty.

Lin Quan opened the storage bag first.

There are a total of three jade slips and two jade boxes inside. The first jade box only contained an old talisman seal, but Lin Quan couldn't tell the name and purpose of this talisman seal. In desperation, he could only secretly keep in mind the characteristics of this strange talisman in his heart, and wait for the opportunity to inquire slowly in the future. As for the second jade box, there are two "Yin Yang Traceless Pills", as well as a Dan Fang of the Yin and Yang Traceless Pills.

"It seems that the key is still in these three jade slips. Lin Quan was a little excited, and after he put away the two jade boxes, he immediately picked up the three jade slips and put them on his forehead one by one to examine them carefully.

Among the three jade slips, the first one records all the classics of the UnXuan Array Dao Technique and the Mechanism Technique that Du Hongbo has left in this branch, and the second is Du Hongbo's experience and experience in cultivating immortals for a hundred years. As for the last jade slip, it was forbidden to be placed, and if Lin Quan didn't have a condensation stage cultivation, he couldn't view it at all.

This result made Lin Quan feel a sense of loss. After working hard for a long time, how do you know that the problem is back to square one, although it is impossible to talk about nothing, but what he is most concerned about is Du Hongbo's whereabouts and explaining his own affairs.

"Well, it seems that I will have to wait until I have successfully advanced to the condensation stage. Lin Quan shook his head, a thoughtful look on his face.

Things that can only be known if there is a condensation period cultivation are indeed useless to him now. In addition, judging from Du Chongbo's arrangement, Lin Quan also knew the difficulty of this task, and now he could only work hard to strengthen his strength.

After putting this matter aside for the time being, Lin Quan's gaze shifted to the simple gray-black bracelet. After Lin Quan's identification, he found that this quaint bracelet was actually the space bracelet used by the ancient monks. However, when he used his spiritual sense, he could only let out a wry smile again, and it turned out that this thing was also banned. Based on his previous experience, Lin Quan preliminarily judged that the requirements for opening this space bracelet were higher, and it was not up to him to what extent it would go.

"It seems that my cultivation is still too low. ”

After working for nearly a night and only getting such a result, Lin Quan's heart was full of bitterness. However, since Du Hongbo and the predecessors of Weixuan have set standards, he can only temporarily break some thoughts in his heart.
