As time passed, the purple dragon formed by the convergence of countless star seals did not know how far it had extended in the secret realm, nor how many places it had sealed the secret realm, Tang Chen only felt that the special star power emerging from the entrance of the secret realm was gradually decreasing.

This means that the seal is valid.

Seven days later, at the entrance of the secret realm, the special star power was no longer bubbling out, only a very small bit leaked out of it, and if you didn't feel it very seriously, it would almost be imperceptible.

These days, the sound of wind and thunder in the void has never stopped, and now the sound is extremely terrifying, "booming and booming" as if tens of thousands of thunders are exploding at the same time.

Not only that, Tang Chen also saw countless black cracks of different sizes appear in the void, and the entire sky looked like a piece of jade that was about to shatter, which was shocking!

"Those are all spatial cracks, right? It seems that the time for the purple cow to leave is not far away......"

Tang Chen looked at the void worriedly, thinking with mixed feelings in his heart.

"Click......"

At this moment, an earth-shattering loud bang suddenly erupted, and the cracks in the void suddenly exploded and shattered, revealing the nothingness of a black hole, and a huge suction force came from it, as if it was about to swallow everything below.

"Woo woo woo ......"

Suddenly, the wind roared, flying sand and rocks, and leaves flying, all rolled into the air, converging into a stream of sand and dust, surging into the pitch-black nothingness.

Tang Chen stood there, feeling that he was almost swept away by this suction, and hurriedly used the realm imperial technique "Mountains and Rivers Seal" to build a field with a radius of 100 meters, forming a relatively independent and stable space, which barely shielded this suction.

As soon as he finished doing this, he heard the voice of the purple cow's soul sense: "It's not good! The secret realm is not completely sealed! Put away the secret key! By the way, be careful......"

Before he could finish speaking, the huge purple cow in the void had already disappeared.

And at the moment when the purple cow disappeared, the magical suction force also disappeared, as if the shattered void was quickly bridged, and in just a few breaths, it returned to its original state.

At the same time, a thumb-sized purple bull-shaped jade plaque fell from the air, Tang Chen's heart moved, and a palm made of star power condensed roared out, grabbed the jade plaque, and received it in his hand.

There is no doubt that this jade plate must be the key to unlock the seal of the secret realm.

Tang Chen carefully put away the secret key, and then looked around, the entrance to the secret realm had disappeared, and only an extremely faint trace of special star power seeped out.

The trees, grasses, and other things in the valley were destroyed by the previous suction, and the eyes were full of desolation, especially the towering ancient tree, which was originally lush and green, but now the leaves of the tree had fallen away, and only the bare trunk remained......

"Purple Cow, take care, I hope I will have a chance to see you in the future!"

Tang Chen prayed silently in his heart, then rode on the white tiger and ran towards Hanyang City without hurrying.

On the back of the tiger, he activated the communication star device and sent a message to Chen Jun to inform him of the news of his safety, and by the way, he also learned about the situation in Hanyang City in the past seven days.

As expected, the movement made by the purple cow was too big and lasted for a long time, not only Hanyang City, but also Qingshan City, which was said to be hundreds of miles away, also saw the vision in the sky, and all kinds of speculation followed.

Some people say that this is a sign of the appearance of the Supreme Treasure, some people say that this is a vision of the transformation of the emperor beast, and some people even say that this is the image of the ascension of the emperor beast......

Tang Chen listened to Chen Jun's narration, and faintly felt that something was wrong in his heart, such a big movement, I am afraid that it would attract the attention of many forces, if people discovered the entrance to the secret realm that was not completely closed, it would be terrible.

"Senior brother, where are you, do you know what happened?" Chen Jun couldn't help but ask.

Tang Chen disappeared for seven days in a row, although he would send a message every day to report safety, but as soon as Chen Jun thought of him staying with the mysterious purple cow, he couldn't help but connect the visions that had happened in the past few days with them......

Tang Chen was silent for a moment and replied, "I'm on my way back, everything will be said when I go back." ”

Immediately, he terminated the communication, and at the same time, the white tiger stopped, and turned back to run to the entrance of the secret realm.

From the moment he entered the valley, he took out the Exploration Compass and tried to use it to find the entrance to the secret realm.

When the star power is injected to activate the Exploration Compass, the compass's hands flicker, which is a reaction to detecting spatial fluctuations.

After a few breaths, the pointer will stabilize and swing back and forth within a range, which means that there is likely to be a secret space in the direction covered by this range, and you can search forward along the midline of the pointer swing range.

So, Tang Chen held the compass and walked along the middle line.

As he continued to advance, the range of the compass pointer swing became smaller and smaller, which showed that the direction of his search was correct, and the spatial fluctuations in front of him became stronger and clearer.

Half an hour later, according to the instructions of the compass, he came to the entrance of the secret realm, and the journey was very smooth.

Tang Chen's face suddenly became ugly, the purple cow did not hesitate to be squeezed out of this space and cast the sealing technique, but he still couldn't hide the secret realm, this is really frustrating!

Now because of the outbreak of earth-shattering visions, this place is bound to attract the attention of many parties, and in such a small area, it may be difficult for the secret realm not to be discovered.

"Something has to be done......"

Tang Chen secretly thought that the best way could only be to set up a star array that could isolate spatial fluctuations, so that even if there was a realm exploration compass, I am afraid that it would not be detected.

However, once the star array is deployed, if someone with a higher level of star array cultivation comes here, it is inevitable that traces of the star array will be found.

"Let's set up a combination of isolation, concealment, and illusion, and whoever can see the clues of this array must at least be the Imperial Star Array Master. At present, it can only be like this, it can cover up one more day is a day, and when the strength is improved in the future, you can also find another way......"

Then, Tang Chen spent nearly an hour conceiving an ultra-small combination array with a coverage area of only about five meters, and then began to refine the array disc and set out the array.

During this period, Chen Jun saw that he had not returned for a long time, and sent a message to inquire about the situation, but Tang Chen deduced that there was still a little matter to deal with, and he would talk about it in detail after he returned.

After another hour, Tang Chen finally finished laying out the combination array that fused the three major effects of isolation, concealment, and illusion, and when he tried again with the Realm Exploration Compass, he really couldn't detect spatial fluctuations anymore, and as for the naked eye and soul sense search, not to mention, he couldn't see the slightest flaw at all.
