In a small clearing, the old man pointed to his feet, "That shipwreck is right under our feet."

"Underfoot?" Mu Chunfeng jumped without a lack of determination: "Uncle, are you sure? It's a real piece of land under your feet. If we're down there, how are we going to get down?"

"That's not right!" Yang Ming sensed something, and he stuck the Mo Li knife on the ground beside him: "It's indeed empty down here." He looked at the old man, "Uncle, where is the entrance here?"

"I haven't been here in a long time, old man, and I can't remember where the entrance is." The old man shook his head apologetically.

"How so?" Mu Chunfeng was stunned for a while.

"Truth be told, this was originally just a vacant lot, but now there are trees growing all around, so it's not that easy to find." The old man explained.

Yang Ming smiled lightly: "It's okay, if you don't want to go down, uncle, just wait here." With that, Yang Ming began to look around.

"It's fine." The old man obviously didn't want to go down, so he quickly nodded in agreement.

A moment later, Yang Ming found a cave in a bush.

He hurriedly called Mu Chunfeng and the old man: "Uncle, is this the entrance?"

The old man brushed aside the bushes, looked at them fixedly, and then nodded in confirmation, "My lord, this is it."

Yang Ming and Mu Chunfeng looked at each other: "Okay, uncle, you just wait here, you don't have to worry about the rest."

The old man nodded, "Okay, my lord, be careful."

"Mu Gongzi, I'll go down first, you follow me." Yang Ming admonished, and his figure went into the cave.

The cave was very dark, but it couldn't affect Yang Ming at all, and after crawling through the cave passage dozens of zhang long, Yang Ming sensed a large space.

He leaned out slowly and muttered, "There's a boat ahead."

As he spoke, he took out the Night Pearl, and for a while, there was a glimmer of light in the originally dark cave.

After a brief glance around, seeing that it was not in danger, he beckoned Mu Chunfeng: "Mu Gongzi, come in."

Hearing Yang Ming's words, Mu Chunfeng also sped up. After a while, he walked out of the cave.

"Sir, you're really putting your resources to good use." Looking at the night pearl in Yang Ming's hand, a trace of regret rose in Mu Chunfeng's heart. This thing is usually an ornament, but in such an environment, it is undoubtedly the best illuminator.

As he spoke, Yang Ming handed the Night Pearl to him: "I can see more clearly in the dark, you are holding it and following behind me, even if I lose it, I can find you quickly."

Mu Chunfeng took the night pearl and promised, "Okay, listen to Mr."

Yang Ming thought for a moment and advised, "If you feel unwell, or if you hear a wail in your ears, retreat immediately." After hearing the old man and Lu Yu's narration, Yang Ming didn't dare to take risks at will, even if he believed in science, his life was still more important. This sentence is not only for Mu Chunfeng, but also for himself.

"Sir, do you feel like it's stuffy here?" Mu Chunfeng's forehead already appeared with sweat the size of a bean: "It stands to reason that this is underground, it shouldn't be so hot, it seems to smell of sulfur."

Yang Ming shook his head and explained, "This is a karst cave, which was originally washed out by water, and there seems to be a hot spring nearby." In the darkness, Yang Ming could only see at a limited distance, and he could only barely see the outline of the ship now.

"There should be a volcano around here."

Mu Chunfeng suddenly remembered something: "Sir, there is indeed a volcano to the east dozens of nautical miles away. I think this must be a branch."

Yang Ming nodded and didn't think about it anymore. Such an environment is nothing to him, as long as he ensures that Mu Chunfeng does not have problems.

"Mu Gongzi, since this place is close to the volcano, maybe there are natural crystals in this cave, we will walk against the rock wall later, if you see it, take some with you."

"Sir, but lack of money?" Mu Chunfeng thought about it and asked.

Yang understood him, "Whether there is a shortage of money or not, since you are here

Here, let's take some souvenirs back with you."

"Souvenirs?" Mu Chunfeng muttered, then nodded, "I understand."

With that, the two walked slowly in the direction of the sunken ship, and Yang Ming also asked Mu Chunfeng's physical condition from time to time. Everything is fine.

"Sir, there seems to be something above our heads." Mu Chunfeng said nervously. The light of the Night Pearl could not travel far, and he could only see a rough outline.

"It's a bat." Yang Ming said, "There should be other entrances here, otherwise such a big ship would not have sailed in."

As he spoke, Yang Ming used his true qi, and a strong wind blew up in an instant, blowing away all those bats.

"These bats are always going to get in the way, and it's scary to pop out of nowhere."

After staying for a while, seeing that all the bats had flown away, Yang Ming and the two continued to walk forward.

The road was unimpeded, and they soon came to the shipwreck. Looking at the reddish-brown attachment on the hull of the boat, Yang Ming reached out and touched it, "Huh? Rust?"

"Sir, this is an iron ship." Mu Chunfeng patted the hull of the boat and gave the answer.

The ship's laughter is no different from that of a cedar longship, the only difference being that the ship is not made of wood.

"No wonder they've been able to sail for so long, they used iron ships, that makes sense." Mu Chunfeng said thoughtfully.

Yang Ming touched his chin and asked, "You don't seem surprised at all."

"Surprised?" Mu Chunfeng was puzzled: "Sir, why is Mu surprised?"

"It's an iron ship!" Yang Ming emphasized, "It seems that Beili can't make an iron ship until now, and the same is true for Nanjue. Not to mention hundreds of years ago."

"That's right!" Only then did Mu Chunfeng notice: "What is the origin of that person, he can actually make an iron ship! How did he keep the iron suspended in the water?"

Seeing that Mu Chunfeng's reaction became a little sluggish, Yang Ming hurriedly asked, "Mu Gongzi, is there any discomfort?"

At this time, Mu Chunfeng was already sweating profusely, and he nodded: "Sir, it seems to be getting more and more stuffy here, and Mu is a little out of breath."

Hearing this, Yang Ming hurriedly wrapped Mu Chunfeng with his true qi, "How is it now?"

Mu Chunfeng took a few deep breaths and said with a relaxed face, "It's much better now."

"Do you know where the ship's number is?" Yang Ming asked, it would be much better to determine the ship's port number first, and then look for the ship's departure record.

Mu Chunfeng thought for a moment and said, "Generally, the ship's side number will be engraved under the bow, except for pirate ships."

"Okay." After a general glance at the position of the bow of the boat, Yang Ming hurriedly walked over with Mu Chunfeng.

It's just that the bow of the ship has long been corroded by rust, and it is difficult to see clearly in the limited light of the night pearl.

"Let's step back a bit."

Retreating to ten zhang, this is already the limit of Yang Ming's ability to see things clearly in the dark night.

Even though the handwriting is very illegible, you can still make out the general text on the ship.

Moli!
