When there was still a distance of more than ten zhang from the archway, Shi An stopped and quietly hid in a dark corner.

With the lesson of the last time, he did not dare to use his divine sense, only watched with his eyes, and on the other side of the archway, fifty zhang away, the four disciples guarding the mountain gate were constantly wandering back and forth patrolling, very vigilant.

Shi quietly observed for a while, and just when the four of them happened to leave a dead corner in the archway, he immediately threw out a small stone slab and a Tianmu array plate, and hid to the side, watching the scene reflected on the jade screen.

The small stone slab and the fist-sized Tianmu array disk have reached the kill range of the archway, and a halo the size of a grinding disc appeared on the top of the archway, and after the sound of "Zilala" thunder and lightning gathering, I saw a straight thunderbolt shoot out from the middle and hit the stone slab, with a crisp sound of "pop", the stone slab was shattered, and during this time, the Tianmu array disk continued to rush forward for a distance.

After a breath, the thunder and lightning sound of "Zilala" sounded again, and that aura also emitted a thunderbolt again, hitting the Tianmu Array that had fallen to the ground. At the moment of destruction, Shi An finally saw clearly that the corner of the lower part of the gatehouse was where the formation was, and he also saw the formation that could stop the formation.

"Bang" made another crisp sound, and the jade screen in front of Shi An's eyes was pitch black, and the Tianmu array turned into powder.

The sound alarmed the disciples who were patrolling, and they all stopped and looked at the archway.

"It's all right, there must be two more birds passing by, so let's go on patrol, brothers. The leader on duty today is still Meng Chuan, and seeing that there is nothing special, he said with a big grin.

Seeing that they were leaving, Shi An recalled the time interval between the lightning strikes just now, carefully calculated the distance, and finally gritted his teeth, untied the Dongtian Stone, saw where the formation eye of the archway was, and after throwing a small stone slab and Dongtian Stone again, he also flew towards the archway with his divine sense.

The thunderbolt continued to attack, and a crisp "snap" sounded again.

Meng Chuan and the others were just surprised that they kept passing by the birds tonight, but they didn't stop, and he muttered: "What's the matter today, could it be that the birds are also rushing to the market? ”

Shi An couldn't hear these words.

At this time, he was in the cave stone. The result of that throw just now was that the small stone slab was unexpectedly struck into ashes by lightning, and when the power of thunder and lightning was formed for the second time, he had already jumped into the Dongtian Stone and landed firmly next to the formation in the lower part of the archway, only an arm's length away from that formation. When the Cave Stone disappeared, the thunder and lightning just arrived here, but it was empty.

He meditated in the cave for a while, firstly, to prevent Meng Chuan and the others from intensifying their patrols when they suspected the movement just now, and secondly, to calm his tense nerves so that he could take the next step.

For half an hour, he deduced the next steps many times, and when there were no problems, he shot again.

This time out of the hole, he still used a small stone slab as a backhand preparation, at the moment of throwing the stone slab, Shi An, who jumped out of the cave, had already touched the spiritual source at the eye of the array with his right hand, and before the "Zilala" thunder and lightning gathered, a spirit stone had been taken down by him.

Shi An in the dark looked around, Meng Chuan and the others in the distance did not notice anything unusual, and were still patrolling in a decent manner, so he put his mind at ease and carefully watched the structure of the formation.

What he got in his hand was a medium-grade golden spirit stone, and there were eight spirit sources in the formation, except for a high-grade ordinary spirit stone, the remaining seven were all medium-grade spirit stones, but there were no thunder spirit stones that Shi An expected, but two medium-grade golden spirit stones, two medium-grade wood spirit stones, two medium-grade fire spirit stones, and one medium-grade earth spirit stone.

He carefully observed the entire formation diagram and each formation symbol, and as expected, this formation was the "Mixed Yuan Array", and no modifications were made.

In the identification function area of this formation, he found the formation that recorded the breath of the person who was allowed to pass, this formation had six rune grooves, Shi An understood that this was a total of six kinds of breath that could enter and exit, four of which were thinner and were simple single straight lines, two were thicker, and there were several forks beyond the straight line.

He silently calculated in his heart that there were four types of people who could enter and leave Wuluobao at any time, namely inner disciples, elders, castle masters and guests, all of whom had their own waist cards, and the aura carried by these waist cards was naturally very different, which should correspond to the four thinner runes. Outer disciples can only enter at a special time, and the rune that records the breath must have one more function to control the entry and exit time than other runes, and this rune is bound to be more complicated, and it is inevitable to add some forks. Shi An hadn't studied this kind of rune, so he couldn't understand it at all.

What kind of person's waist card is recorded with a complex rune left, and what is the time of control? Shi An couldn't figure it out, and the current situation didn't allow him to think too much about it.

took out the talisman knife, and on this array talisman he carved the fifth path according to the four runes according to the gourd drawing, and took out the obsidian card that the monk Jingyi gave him to hang on his waist, and sent the breath in it into the fifth rune, and the rune flashed and returned to calm, Shi An knew that this breath had been recorded. He secretly rejoiced in his heart: it would not be so troublesome to enter and exit this place in the future.

There was no special structure anymore, Shi An put the golden spirit stone back as it was, and with a soft "buzz", this formation was restarted.

As he expected, the formation after recording his obsidian waist card breath no longer paid any attention to his existence as an outsider.

It only took more than an hour to complete the purpose of probing the formation, although he didn't know why that formation would release thunder and lightning, but all the details were already in his eyes, and he believed that it wouldn't take long for him to figure it out.

Shi An, who was in a good mood, walked the way he came.

Passing by the Prison Dragon Cave again, he was moved, why didn't he go in to see the female prisoner again, maybe he could get some secrets from this as the remnant of the rebel castle.

Still using the "Boundary Array Disk" to enter, with the experience of the last time, this time Shi An walked straight to the center of the mountain room.

The female cultivator was still unconscious, and Shi An still gave her a trace of wood aura, and then waited for her to wake up leisurely.

"Is that you?" Shi Sakura asked in a faint voice when she saw someone in front of her.

"If you're talking about the one who used the water shield to keep your spittle out, you're right. Shi An replied teasingly.

"Why are you here again?" Shi Sakura didn't seem to have the strength to open her eyes again, and asked with her eyes down.

"I'm fine this time, I'm here to see you. Shi An said half-truthfully.

"Can you show me your face?" asked Shi Sakura after a moment's breath.

"Wait a minute. Shi An did not refuse, and then quickly carved a "shading array" around the two with a talisman knife, and then lit up a piece of fluorite and placed it between the two.

When he saw the nun's condition clearly, he couldn't help but gasp.

There is an extra layer of skin than a skeleton This is Shi An's first impression when he sees her, a black power suit that should be close to her body seems to be like a fat burqa, exuding a pungent smell of rotting flesh, and the dense fat white maggots are wriggling happily, making people feel indescribably disgusting.

Shi Sakura's face was extremely pale, her barely open dark eyes were sunk deep into the sockets, her cheeks collapsed, and her cheekbones were unusually prominent, and a thumb-thick iron chain surrounded her neck, apparently piercing the lute bone.

In Shi Sakura's eyes, the monk in front of him was tall, and his tight-fitting black night suit showed his sturdiness even more. Although his face is not handsome, the shrewdness of his smart eyes is unforgettable, and his long beard gives the impression of perseverance and courage.

Shi Ying's pupils dilated suddenly, and she asked in a trembling voice, "Do you have the surname Shi?" or Hai?"

Seeing her extremely excited expression, Shi An'an was full of doubts, but he still replied honestly: "My surname is Shi, and my name is Shi An." ”
