Surprise! The boss of the last days, reborn before the engagement

The entrance of Ghost Doctor Valley is shrouded in a hazy mist. The sunlight shines through the gauze-like mist, sprinkling on the verdant mountains and winding paths, adding a bit of mystery and vitality to this quiet valley.

Chu Yiyi stood at the entrance of the valley with a deep gaze, having a silent conversation with the system in her heart.

She thought to herself, "System, is there a hybrid formation in the mall that combines a psychedelic formation, a trap formation, and a killing formation?"

The familiar and mechanical voice of the system then rang in her mind: "Yes, host. This mixed formation is divided into several levels. The low level requires 3,000 points, the middle level 6,000, the high level 9,000, and the ultimate version requires 12,000 points."

Chu Yiyi heard this and a sly smile appeared on her lips. She thought to herself, "Tongzi, we have such a good relationship. I will give you 10,000 points for this ultimate mixed formation, right?"

The system seemed to be able to sense Chu Yiyi's expectations, but it still maintained its businesslike attitude: "Host, Tongzi can allow you to owe 2,000 points first, but you must pay it back within seven days.

It's not that Tongzi is unwilling to give you a discount, but it's controlled by the main system, and Tongzi can't do anything about it."

Chu Yiyi sighed softly, but then regained her determination: "Okay, then you can give me more tasks! I will pay back the points as soon as possible."

The system agreed, and then a message came: "The ultimate hybrid formation has been successfully exchanged for the host, and the item has been sent to the system backpack.

The system has deducted 12,000 points, and the host's current remaining points are negative 2,000. Please work hard to complete the task to repay the points. "

Chu Yiyi took out the mixed array disk that was emitting a faint glow from the system backpack and asked: "How do I use this mixed array disk?"

System: "You drop a drop of blood on the array plate. After it recognizes the master, it will do whatever you want. No matter where you are, you can see the situation at the entrance of Ghost Doctor Valley, and you can also control the mixed array. The array plate can make you invisible."

Chu Yiyi sighed: "No wonder it's so expensive...there is indeed a reason why it's expensive."

She followed the system's instructions, gently bit her fingertips, and dripped a drop of blood onto the formation disk.

In an instant, the light seemed to come alive, spinning around her fingertips, and finally turning into a tiny stream of light and merging into her body.

As this stream of light merged, a subtle connection was established between Chu Yiyi and the formation disk.

She could clearly feel every subtle change in the formation disk, and could even foresee the amazing power it was about to display.

"So that's how it is..." Chu Yiyi murmured to herself, her eyes gleaming with excitement and anticipation. She raised her hand slightly, and saw that the array disk seemed to have disappeared into her palm.

Chu Yiyi held in her hand an invisible array disk that was gleaming with light. She was focused as she gently placed the array disk on the ground.

As a subtle buzzing sound was heard, the entire Ghost Doctor Valley seemed to be shrouded in an invisible force.

The familiar voice of the system sounded in her mind, analyzing the power of the formation disk for her, "The protection range of the formation disk has completely covered the Ghost Doctor Valley. From now on, as long as you are in the valley, you will be safe even if a large army approaches.

First of all, the enemy will not be able to find the entrance to the valley, even if they enter the valley by mistake, without the permission of the host or the people in the valley.

They will be forever lost in the formation, and the final killing formation is enough to turn anyone who dares to invade into cannon fodder."

After hearing this, Chu Yiyi nodded slightly, expressing her satisfaction with the defensive power of the magic disk. She knew very well that in this turbulent ancient world, having such a powerful protective force would undoubtedly be a solid barrier for the Ghost Doctor Valley.
