The succubus that appeared tonight was more difficult to deal with than Liu Yanyu who was possessed by a monster during the day. Yu Qinzhu was obviously trapped in a tough battle.

"I just hope Sister Yu has other trump cards in her hand that can turn the tables..." Bai Mufan thought optimistically.

After a moment, the movement outside suddenly stopped.

Bai Mufan was nervous and said to himself: "It's over? Did Sister Yu win?"

He just thought of this when a graceful figure suddenly ran into the basement from outside. Bai Mufan looked over nervously and couldn't help but breathe a sigh of relief. It was Yu Qinzhu.

But then his heart hangs again, because Yu Qinzhu's appearance is not good-looking at this moment. In addition to the blood hole on her shoulder, there are also a few deep bone-deep claw marks on her back and arms. It seems that it was injured by the succubus' claws. The blood gushing out of the wound has dyed most of the golden armor on her body red!

Moreover, the armor on her body was extremely damaged, and most of the places were completely broken, and only a small number of armors barely insisted on protecting the key points.

No matter how you look at this look, you have experienced a hard battle. Looking at Yu Qinzhu's solemn expression, it is obvious that the succubus has not been solved by her!

After Yu Qinzhu rushed into the basement, he closed the door with his backhand as soon as possible, and then took out an inconspicuous black flag from his body.

She activates the power of the martial soul with a serious expression, allowing the power of the martial soul to flow, slowly entering the black small flag.

"Buzz!"

The black flag suddenly shone brightly, and the flag fluttered automatically without wind. The light flowed on it, extremely gorgeous, making the basement bright!

The flag was trembling, and the amplitude became larger and larger, which made Yu Qinzhu's arms numb, but she did not hold on to the small black flag, and naturally let go of her hand and threw it into the center of the basement.

Bai Mufan came to his senses, and quickly moved away from his position, then watched the black flag rotate and land with curiosity, suddenly expanding and becoming larger, rotating in place, and then suddenly shot out the small black flag on all four sides, and inserted it on the four walls of southeast, west and north!

Most of the small flags on the walls were deeply penetrated into the walls, only the flag at the top was exposed outside, buzzing.

Bai Mufan looked closely and saw that the four divine beasts, such as the blue dragon, white tiger, vermilion bird and black womb, slowly appeared on the flags flying on the four small flags!

"Swish, swish, swish!"

Four faint lights suddenly projected from the small flags on the four walls, closely connected to the large black flag in the center. Countless dense golden symbols slowly emerged on the black flag!

Bai Mufan couldn't help but look at it, but found that he couldn't understand any of the symbols on the flag. He just felt that these ghost paintings looked inexplicably comfortable, which is commonly known as "pleasing to see".

At this time, Yu Qinzhu, who was standing on the top of the building, suddenly shook his body and fell forward. Bai Mufan hurriedly ran over to catch her, but felt that Yu Qinzhu's body was extremely heavy, and he couldn't help but take several steps back, and then he barely stabilized the center of gravity and did not fall.

"Sister Yu, are you seriously injured?" Bai Mufan looked at her worriedly.

Yu Qinzhu shook her head, and she stood firm and said, "This kind of injury is very fatal to ordinary people, but it can be withstand it for warriors like me. Our warriors have many times more vitality than ordinary people. As long as they are not serious injuries that hurt the heart and other key parts, they can hold on for a long time and even slowly recover. However, although the succubus left me this injury, she couldn't have a good time. I tore off one of her wings and broke several nails."

Seeing that she didn't seem to be holding on, Bai Mufan felt relieved. He turned his head to look at the five big, four small flags in the basement, and couldn't help but ask curiously: "Sister Yu, what are these flags?"

"This is the simplest four-simile formation. In the middle is the main formation eye, and the walls are the East Qinglong, the West White Tiger, the South Vermillion Bird, and the North Xuanwu. Maintain the power of the four-simile, guard the four directions, and resist the attack of foreign enemies." Yu Qinzhu explained: "This is the last trump card on me. The four-simile formation can temporarily put this basement in a safe situation, making it impossible for the succubus outside to attack."

Bai Mufan nodded in a clear way, and he could understand the Four Symbols and the Formation.

"Bang!"

At this time, a loud noise suddenly came from outside the basement door, as if the succubus was hitting the door hard outside!

He looked at the door nervously, and saw the black flags of the North Xuanwu and the West White Tiger near the door suddenly glowed slightly, and an invisible barrier emerged, covering the door, resolving all the forces from outside the door, making the wooden door that looked extremely ordinary persist intact!

Bai Mufan was a little surprised, and then he breathed a sigh of relief. Is this the power of the Four Symbol Formation? It turns out that the effect is amazing!

Yu Qinzhu slowly sat down against the wall. She looked at the door of the basement that was constantly rippling, and said with a serious expression: "That succubus is very strong. The time it can last for this simple formation is limited. She can only protect us temporarily. Sooner or later, she will use up the energy in the formation and attack in. However, this is my last resort. During the period of delay, I will try my best to recover from my state and injury, but I do not carry healing drugs on my body. The degree of recovery in just a few hours is extremely limited, so it is best if someone can detect the abnormality here and come to support it."

Hearing this sentence, Bai Mufan couldn't help but feel guilty and whispered: "I'm sorry, Sister Yu, although the phone you asked me to call was called, I was broken by the succubus before I could explain the situation there..."

"No, this is definitely not your fault with Brother Bai. It is because my lack of ability and failed to block that succubus, which gave her the opportunity to approach you and take away the phone." Yu Qinzhu shook her head and said in a low voice: "I didn't even notice when the succubus sneaked into your bedroom in time. If that guy hadn't been too confident, and Brother Bai, you have been persisting for a while and have not been controlled by that guy, otherwise the succubus would have succeeded now."

She clenched her fists quietly, with a hint of reluctance and self-blame on her face.
