Walking through a pile of rubble, one finally got a clear look at the object, a tall stone statue that was beneath the pile of rubble, most of which had been covered in rubble and dirt, and even then, the exposed part of the ground was nearly three or four meters high.

There used to be some paint on its surface, but now only a few bits of color can be seen over time.

Even after an unknown amount of time, the stone carvers could still vaguely recognize its appearance.

It was a dinosaur that had never been seen before, and its teeth could tell that it was a herbivorous dinosaur.

"Lang, what is this, how did it end up here." Lin Huo looked at the huge stone sculpture in horror and asked suspiciously.

Wang Lang shook his head and looked around it carefully.

The others were obviously interested in this thing as well, but their duty was to disperse around the stone sculpture and remain vigilant.

Wang Lang frowned, the appearance of this stone carving proves that the civilization that once appeared here has an extremely advanced carving technology, and it can make such a large stone carving, which primitive people can't do at all.

Looking at the ruins of this city, Wang Lang couldn't help but ask himself: "What happened here, this civilization seems to have disappeared without a trace overnight, does the bronze handicraft that appeared in the copper mine have anything to do with this civilization?" ”

With the appearance of various relics of this unknown civilization, Wang Lang became more and more curious about it, but Wang Lang is not an archaeologist, so he can't tell how many years ago this place, but judging from the degree of stone weathering, he conservatively guesses that this civilization has disappeared for at least a thousand years.

As it darkened, the expedition rested under a somewhat intact wall.

"Chief, was this once inhabited by humans?" Kong Yi asked.

Wang Lang shook his head and said: "I don't know, but it doesn't matter to us whether there were people living here before, they have disappeared, and this place will be called the Lost City in the future, so let's come here again if we have the chance!" ”

Although this lost city is mysterious, for everyone, the main concern is when they will be able to return to the tribe.

After a night's rest, the expedition continued its journey.

Half a day later, when everyone passed by a waterfall, they made a new discovery.

"Lang, there's tin ore here." Lin Huo said in surprise.

Wang Lang looked at the faintly shining metallic stones in the river, and smiled almost from ear to ear, these exposed tin ore proved that the output here will definitely not be less.

"It seems that we really have an unexpected harvest this time, remember the location here, return to not lag behind, and immediately send someone to mine." Wang Lang said excitedly.

People have long known that copper with tin is far from being comparable to pure copper, and the current bronze weapons of the tribe are only Wang Lang's short sword and the dagger in Jianya's hand.

But now that these tins have been discovered, of course Lin Huo and the others know what it means.

Thinking of having a bronze weapon of their own in the future, the two of them flushed with excitement.

Although tin ore was discovered, people could not mine it now, so everyone just picked up a small piece of tin ore nearby, took it with them, and continued to the northeast.

After a day's walk north, the expedition finally came out of the jungle and saw the familiar grassland.

"We're finally out there!" Lin Huo said excitedly.

"Chief, where are we going this time?" Kong Yi asked.

Wang Lang looked at the direction, and then said, "Heading north, we just need to walk along the edge of the forest, and we should be able to return to the tribe." ”

Coming out of the jungle and boosting the morale of the expedition team, this adventure is of great significance to them, as long as they return to the tribe, everyone can make a note in the credit book, even if they can't immediately be equal to the old people of the tribe, but at least one name is in hand.

A day later, the expedition finally saw the familiar lake.

At this moment, on the lake, several huge rafts are quietly standing in the middle of the lake, and you can faintly see that there are people moving on the rafts.

The bark of the tree, who was directing the fishing, saw an unknown team appear in the south, and he was shocked, and he didn't care about the harvest this time, so he hurriedly asked people to collect the net and row the raft towards the shore.

When the raft gradually came to the shore, after the bark saw that this team was Wang Lang and them, his tense nerves suddenly relaxed.

Before the raft could dock, the bark was picked off the raft and walked quickly towards Wang Lang.

"Chief, you're finally back." Bark said happily.

"What, what's going on in the tribe?" Wang Lang asked.

Bark shook his head and said, "It's not a big deal, it's just that everyone is very worried about you. ”

Wang Lang nodded and said, "Let's go, this time the harvest is not small, go back and talk about it, the soldiers are tired." ”

Bark smiled, and hurriedly asked his subordinates to take what the expedition had brought back, and everyone returned to the tribe together.

The return of the expedition team brought the lifeless tribe to life.

Curious people asked the soldiers returning from the expedition about what they had seen along the way.

Wang Lang summoned the big and small leaders and gathered them for a meeting.

"This expedition was a great success, and we want to turn our development goals to this jungle in the future." Wang Lang said slowly.

"Chief, what about our training?" Kong Yi asked.

"Let's put aside the training for a while, the current level of the soldiers is enough to deal with a war, and our most urgent task is to develop this jungle." Wang Lang said.

"Chief, are we really going to build roads?" Kong Yi asked.

Wang Lang nodded and said, "The road must be repaired, without the road, we can't make use of those fruits and tin ore at all." ”

"Then which road do we build first?" Lin Huo asked.

Wang Lang thought for a while and said, "I have decided to send half of my men to the tin mine from tomorrow, first use a basket to transport tin ore back, and after preparing enough tools, I will build these two roads at the same time." ”

After discussing for a while, the others also agreed with Wang Lang's approach, as long as the tools were all bronze, the efficiency of cutting down trees would be greatly increased many times, and it was not impossible to build two roads at the same time.

"Since you have no opinion, you can go and tell your soldiers, select the right manpower, and tomorrow Lin Huo will lead the team to collect tin ore." Wang Lang said solemnly.

"Yes!" Everyone responded in unison.
