Outside the cave, on both sides of the creek there are many large pieces of gold, which are not pure in texture and have many impurities in them, presumably quartz-like associated stones.

Qin Fengyi was holding a machete and was about to open this red wooden box, the wooden box had been hidden in the cave for an unknown amount of time, the metal lock on it had become rotten, and he didn't need a key to open this box, just cut it with a knife!

"Click~!"

"Open it, let's see what's inside?" Lin Qingxue was quite interested in the unknown, and was jumping in front of the wooden box.

"Don't worry, you guys stand back first, I'll take a look!" Qin Fengyi carefully picked open the box with a machete, and there were 2 things lying in the box, one of which was a piece of metal that Qin Fengyi had been trying to find!

The other half of the metal key!

The other is a special fur, like another part of a treasure map!

"Key!" Qin Fengyi picked up the strangely textured metal in the treasure chest, "I finally found the other half of the key!"

"The other half of the key is actually hidden here!" Han Xuening kept the other half of the key, and the beautiful teacher carefully took out the other half and handed it to Qin Fengyi, and then he slowly spliced it together.

There are two gaps between the two keys, and the fit is quite high, and after they are connected together, there is no gap or anything like that.

"Finally...... Finally found ...... Hahaha, the secret room of the ancient city!" Qin Fengyi looked at the metal key in his hand, this key had a strange shape, and it should be able to open the door of the secret room of the ancient city.

"Qin ...... Fengyi ...... Let's take a look at the treasure map!" Han Xuening took out the treasure map she had now collected, put it together with the one she had just found, and found some other maps, which had buildings on them.

"What's wrong with the treasure map?" Looking at the treasure map, Qin Fengyi's face became gloomy.

The heart of the island!

The treasure map depicts the center of the island, with a huge cross drawn on it, and a skull, which seems to be a dangerous place.

What is it?

Is it forbidden to be civilized?

On Saturdays and Sundays, they leached out of the caves, and every time they came out, they would bring out a large piece of gold, which looked quite good, not some scattered gold ore, but a whole piece of gold.

"Damn, so much gold, to say the least, there are several tons, right?" Lin Qingxue was frightened by the metal carried out by the giant apes, this ......

"Is this a gold mine?" Han Xue stared at the dark cave, where the river was slowly flowing, and there were many small pieces of gold ore washed out by the water.

"Well, that's where the treasure on the treasure map is. Qin Fengyi said lightly, he had studied in the gold mine cave just now, and the road leading to the canyon was blocked by falling rocks, and if he wanted to pass from that side, Qiao cleaned up the falling rocks.

"All right, Saturday and Sunday! Now dig the channel of the canal and see where the river goes. Qin Fengyi looked at the gold on the ground, it had already accumulated a lot, these could be brought back and smelted later.

"Woo woo wow~!" the giant apes knelt on the ground very obediently, and then used iron pickaxes to dig the barrier of the canal, and then blocked the original channel of the river.

"Boom~!" The river flows down the dug canal and connects to a very low-lying location, and then the river flows downstream, and it seems to flow into the cactus field on the side of the bamboo forest.

"We ...... Go back?" Lin Qingxue asked, pursing her lips.

"Go back!" Qin Fengyi looked at the prehistoric salamander corpse on the ground, "This can be brought back to taste." ”

"I just want to know what it tastes like. "Lin Qingxue is not the first time to come to a desert island, she has experienced so much, and her mentality has become very tenacious.

"Amphibian, in vitro fertilization...... Maybe it's the same as frogs. "Qin Fengyi used to eat roasted frog legs when he was a child, and there were many frogs in the big ponds in the countryside, and in the summer, those bear children would use pins to make a hook and catch frogs with woolen line.

Frog fishing is much more convenient than fishing, just put the hook on the frog's mouth and shake it, he will stick out his tongue and swallow the hook, at this time just need to quickly pull the frog up.

When I was a child, the frog caught only ate the legs, generally cut off the frog legs with a knife, and let the upper body disappear by itself, it is also said that the silkworms are cruel, the frogs that lose their legs will crawl slowly with their forelimbs, and the fat frog legs are simply barbecued to make a delicious meal for rural children.

Because of eating roast frog legs, many bear children were beaten, and Qin Fengyi was beaten by his mother many times.

Adults find it cruel...... As everyone knows, they also did such things when they were children, and the reason why children do it is because they learn it from adults.

Cut off a few pieces of salamander meat, this guy's tail is quite good, Qin Fengyi carried two white and tender big tails, and rushed back with a mighty team.

On Saturdays and Sundays, he carried huge gold nuggets weighing hundreds of pounds and followed behind his master.

The way back is not far, just walk back along the river.

The canal that had just been dug was decent at first, but in the second half of the road, it began to become crooked because of the topography, and finally, the end of the river was infinitely close to the shelter, on the side of the cactus field, only a dozen meters away from the shelter.

"This river should be able to flow for a long time, right?" Lin Qingxue looked at the turbid freshwater river, and the river water poured into the sea, once again stirring up the more turbid river.

"I don't know...... Let's take a look at the situation, if you really can't do it, let the giant apes dig a big well!" Qin Fengyi has studied again, the geology on the side of the bamboo forest is quite good, it is basically muddy land, and a lot of water can be stored in the open well here.

When I came to the shelter, I had to start working again, this time Qin Fengyi wanted to make Zhuge Repeater, anyway, there is a lot of gold here, according to the amount of gold, you can make three sets!

"Take a break and continue to carry the gold back and forth. "Qin Fengyi arranged a job for the giant ape, these guys are strong and suitable for hard work.

The lethality of the Zhuge Repeater is very strong, but the weight is a little too heavy, but it can be used by the giant ape, these two guys are 100% loyal to themselves, and arming them is equivalent to strengthening themselves.

Just do it, light the fire and open the kiln!

A few hours later, a repeater was complete!

[Host crafts Zhuge Repeater, forging proficiency +80]

Gold is also a metal, this thing is quite lethal after forging and sharpening, in order to improve the penetration, Qin Fengyi deliberately made a few arrow blades with iron tools, and only need to be connected with gold.

"Saturday! You can try it!" Qin Fengyi looked at his invention with great satisfaction, and called a giant ape over and asked it to use this crossbow arrow made of hundreds of catties of pure gold.
