The two of them quietly got on the road and felt into the valley.

"Lord, the lights in this valley are bright, and there is a faint sound of iron, and they are actually building weapons day and night."

In the second half of the night, the two finally touched the mouth of the valley, and they could see that there were lights everywhere inside, and there were bursts of iron.

"There are dozens of people guarding the mouth of this valley, and it will be difficult for us to get in, so it seems that we have to find other ways." When they arrived at the mouth of the valley, Zhang Yu and the others saw dozens of people guarding there, and it was not so easy to get in.

The two had no choice but to return.

The first day was fruitless, Zhang Yu and they were not discouraged, they simply rested, and waited for the next day to come out to observe after dawn.

The entire valley was still relatively well defended, and Zhang Yu was divided into two directions to reconnoitre.

After searching for a long time, Zhang Yu did not find a way to enter the valley.

"My lord, I found a path behind the valley, and there is a cliff to go down, which is a little more dangerous." At the appointed time, Ling Cao found Zhang Yu and said.

"Let's go, go over and have a look." Zhang Yu knew that dragging it out like this was not a solution, so he decided to take a look, and if he could, he would take a risk.

When he arrived at the place where Ling Cao found, Zhang Yu saw that it was indeed a cliff, fortunately it was not high, it was only twenty or thirty meters, but it was relatively steep.

The cliff is located in the middle of the valley, and if you go down from here, you can just avoid the guards and most of the patrols at the mouth of the valley.

On top of that, there is a lot of shelter underneath, and when viewed from above, there is a lot of ore, dry firewood, vehicles, and various huts underneath.

This provided Zhang Yu with a place to hide, so Zhang Yu decided to go down from here.

"Let's go back and get two rattans, and we'll go down from here." Zhang Yu made a decisive decision and said.

Ling Cao nodded, looking at the still brightly lit valley below, revealing a strange look.

The two of them found some rattan nearby, and then tied the rattans tightly together, and after more than half an hour, they made two ropes that could go down.

"Lord, I'll go down first, and then you can go down when it's safe." Tie the rope to the thick trunk, Ling Cao said to Zhang Yu.

Zhang Yu shook his head and said, "No, it's night now, it's relatively remote here, let's go down together, it's good to take care of it." ”

After Zhang Yu finished speaking, he pulled the rattan and found that it was very tight, so he directly faced the cliff and went down slowly.

Ling Cao saw that Zhang Yu had already started to act, so he didn't say much, and followed Zhang Yu down.

The two of them went down slowly, their figures hidden in the dark night, and they were not discovered by the yellow turbans.

"Bang~"

With a soft sound, Zhang Yu fell to the ground, and then he hurriedly looked around, and there was no yellow scarf around.

Then Ling Cao also landed.

"Let's go."

Zhang Yu whispered to Ling Cao, and the two of them went one after the other and touched into the valley.

"Lord, I didn't expect that the precautions in this valley are so sparse, and there is not even a patrol." After walking for a while, Zhang Yu and Ling Cao shuttled through the valley, but they were never discovered.

Zhang Yu can understand that this is in the deep mountains, and the valley is surrounded by mountains on three sides, and there is only one valley mouth, and they have heavily guarded the valley mouth, so they are naturally not so strict with the precautions in this valley.

There are two very important factors among them, that is, the level of the yellow scarves is not high, and it is generally organized by a group of farmers, and there are not many people who can write in the entire yellow scarves.

Another important reason is that the imperial court has not discovered their conspiracy at this time, so there is no need to guard too closely.

Zhang Yu and the others walked around inside for a long time, and many places inside were building weapons, and a lot of ores, wood and other things were piled up in the open air.

"My lord, this is an iron ore."

Ling Cao saw that there were a lot of yellow turbans busy, and they were transporting a large amount of ore from the valley.

"It's no wonder they're setting up a place to craft weapons, it's really convenient." Zhang Yu looked around, looked at this huge arsenal, and couldn't help but sigh.

"Lord, be careful."

Ling Cao saw the yellow scarf carrying materials approaching, and hurriedly reminded Zhang Yu, and the two of them quickly hid in the ore pile.

"Ling Cao, when I got here, there were too many yellow scarves coming and going, either transporting ore or wood, as well as finished weapons." The two hid for a long time, but they didn't find a chance.

"Yes, my lord, if they work day and night like this, we won't have a chance to check the situation inside." Ling Cao said.

Zhang Yu thought for a while and said: "Actually, it doesn't mean much to us to investigate the specific situation, because even if we find out the situation, it is impossible to report to the official or break through here." ”

"However, if we can gather more information, it will be of great significance for us to deal with the Yellow Turbans in the future."

Zhang Yu's meaning was obvious, that is, to tell Ling Cao that there was no need to take risks, and that he could collect as much as he could.

Ling Cao nodded secretly and did not respond.

After a while, Zhang Yu said: "There is a cart over there, let's push some ore and go in openly." ”

Zhang Yu looked around and saw the cart on the side, so he came up with an idea.

After a while, Zhang Yu and Ling Cao appeared pushing a cart of ore, because they were wearing ordinary people's clothes, and there were yellow scarves on their heads, which looked like two yellow scarves, so they didn't arouse other people's ideas.

The two of them made a few trips to the iron ore to take a general look at the surrounding environment, as well as the workshops here.

It can be said that the people who built the weapons inside were a group of peasants, and few of them knew how to strike iron, because there were a lot of waste products on the ground.

It is understandable that this yellow turban would never dare to recruit blacksmiths on a large scale.

And because the blacksmith has a skill, plus the offerings of some families, he can barely eat, so he does not mix with them.

"We're going to push this cart of ore in and look for an opportunity to sneak into the valley and have a look." Zhang Yu and the others are now in the middle of the valley at most, and there are any secrets inside, he really wants to go in and find out.

"You two come here." Zhang Yu and the others had just pulled the iron ore into the workshop, and they were stopped when they were about to come out.

"Did you find out?"

Zhang Yu and Ling Cao froze, their hearts pounding involuntarily.

"Hurry up, grind." The man cried out again.

took a deep breath, it's a blessing or a curse, it's a curse that can't be avoided.

Zhang Yu turned around with Ling Cao and walked towards the yellow scarf that stopped them.

Ling Cao pinned his left hand to the back and secretly touched the short blade inserted in his lower back.

Zhang Yu's eyes looked around, thinking about where they were going to kill them after the incident.

The sound of striking iron was still everywhere, but Zhang Yu and Ling Cao could hear the sound of their own heartbeat.

Approaching step by step, what the result would be, Zhang Yu tried to calm himself down, thinking about how they would get out once they were discovered.
