"What the hell is this?"

"Brimstone locks, this is the legendary brimstone locks. Kou Feng said firmly. Although he had not seen it before, the refining method of the sulfur lock had long been lost. There are still finished locks in existence, but they are all used in their own treasure troves. This kind of lock will really explode if it is smashed.

"It's actually a sulfur lock!Can you open it?" Yin Susu frowned.

"You can try, but I can't guarantee it!" Kou Feng said truthfully.

"Okay! I'll leave it to you. The rest of the people all stepped back a bit. As Yin Susu finished speaking, everyone left the pit and took a few steps back. Only Kou Feng and Xu Ling were left in the pit.

"Second brother, in fact, I can do it myself!"

"Big brother, don't be stupid! I don't know what you're thinking? If you can't open it after three tests, it will explode! Besides, I don't know if anyone has tried it before us, so how can I rest assured if you let you get it yourself!"

"Second child, listen to me. If we all die, who will avenge the old thief's revenge? Besides, since I am the eldest brother, you should listen to me. I'll let you go now as a big brother!" Kou Feng said as he stared at Xu Ling.

"Big brother, you ......"

"Either go, or don't recognize me as a big brother!" Kou Feng said firmly.

"I, hey, I'm leaving, can't I go?" Xu Ling said with difficulty. "You must pay attention to safety, if not, we are trying to find a way, don't take risks!"

"Second brother, don't worry!, big brother's life is not so easy to die!" Kou Feng finished speaking, staring at Xu Ling and exiting the pit. He took a deep breath and crouched down to carefully examine the brimstone locks. Then he took out a filament from his body, which was the thickness of three hairs, and it was made of a variety of metal alloys, which were both hard and elastic.

Kou Feng lifted the sulfur lock in one hand, and with the other hand held the wire tremblingly and reached into the keyhole. The wire was controlled by Kou Feng's unique technique, flicking up and down in the keyhole, while Kou Feng pricked up his ears to listen to the sound coming from inside the lock. It didn't take long for Kou Feng to have sweat oozing from his head, but he didn't realize it, listening intently to the sound in the lock, and finally he heard the snapping sound he wanted. Not only was Kou Feng overjoyed, he gently pulled out the wire, and then began to make the keys in the order he heard them.

The wire was still alive in Kou Feng's hand, and after being bent around a few times by him, it took on the shape of a key. Closing his eyes and thinking about it, to make sure nothing was missing, Kou Feng gritted his teeth and stuck the simple key into the keyhole and stuck it all the way to the end. As the key turned, there was a clicking sound in the lock. Then there was a click, and the brimstone lock was actually opened by him.

Kou Feng exhaled a long breath of turbidity. He carefully removed the brimstone lock and placed it on the sandy ground to the side. Only then did he realize that his front heart and back were cold, and it turned out that sweat had already soaked through his clothes.

"My lord, I am glad that I did not disgrace my life. The brimstone lock has been lifted!" Kou Feng said to Yin Susu.

"You're very good!" Yin Susu said with a smile. "Now that the lock is open, let's see what's down there!"

"Big brother, are you okay?"

"Second brother, are you still expecting me to have an accident?"

"If something happens to you, I won't be alive!"

"Haha. What a foolish thing to say! Let's go and see. ”

By this time, two people had jumped into the pit, and they lifted the iron door with all their might. However, as soon as the iron gate was lifted less than half a meter, two short arrows flew out from under the iron gate. "Be careful!" Wang Yuan's sharp eyes hurriedly reminded him after seeing it, but it was still too late. The short arrow went straight into the chests of the two men.

"Ahh

"Ahh Yin Susu squatted in front of the two to check, only to see them foaming at the mouth, their faces were pale, and she couldn't help but say, "What a domineering poison!"

The rest of the people are a little worried, but it is impossible to let them retreat. Yin Susu called two more of his men over and said to them, "You two go and open this iron gate." ”

"Wait. Wang Yuan Lao Liu said. "Who has the rope?"

"I've got it here!" Xu Ling said on the side.

"Okay, give me the rope!" Wang Yuan took the rope from Xu Ling's hand and jumped into the pit. He tied the rope to the nose of the iron door, then jumped out and said, "Don't hold the door with your hands, just pull the rope together!"

The two men's eyes lit up, and they grabbed the rope and pulled it back. The iron door creaked and slowly lifted. Suddenly there was a whooshing sound, and three more short arrows were shot out of it. It's up to me to let these two use ropes, or they wouldn't have survived. The iron door was completely opened, leaking a dark passage to the underground, and there was a staircase path with no end in sight.

"Zhou Bin, you lead people to guard it above, can we go down like this, King of Bats?"

"Virtuous niece, take me down slowly, and explore the way first. I've always felt that this road is not that simple. The Blue-Winged Bat King said.

"That's fine, it's just bothering you. After Yin Susu finished speaking, the Blue Winged Bat King shook the cloak behind his back, and his body flew into the passage like a puff of smoke. The people above looked anxiously at the passage, but after waiting for most of the hour, the Blue Winged Bat King did not come back. Yin Susu was a little anxious, and she said to Wang Yuan, "Why has the Bat King been gone for so long?

"The Wheel Light Gong Bat King is alone in the world, and it is estimated that he is trapped if he hasn't come out yet!" Wang Yuan frowned.

"I think so, I can't wait. Let's go down too!"

"Good. But you can't go down!"

"Why, the shopkeeper, you also look down on women?"

"What do you say? Am I such a superficial person? But it's complicated down there, and we need someone to answer it up there. It will help you more to stay on it than to go down, and besides, these people above only listen to you, and it is not easy for others to speak. Wang Yuan explained.

"Then who's going to lead the team?"

"Me!" of course I led the team down. "Inn, don't lie to me, you must protect me if you are in danger!"

"Don't worry, slave, you can't die easily with me!"

"Then let the Empty Daoist and Lady Zhou take someone to accompany you. Yin Susu said and looked at the two. Both of them nodded, they had brought back the treasure map, and they had long wanted to go down and take a look.

After they had discussed it, they took out the torches they had brought with them and lit them, and two of their men opened the way, and a group of five people walked down the steps.

It didn't go far before it was a turn, and he didn't go too far after turning around, and the scene in front of him really scared Wang Yuan. I saw that the bones of one place were paved all over the road ahead, and I am afraid that there are dozens of people if not a hundred. Although they were all reduced to bones, it could be seen that they had been killed by hidden weapons shot from the walls on both sides, and they had been dead for an unknown number of years.

"Is this the Trap?" muttered the Empty Path Man.
