The trio spent three days in the Green Swamp area before completing the 20-square-kilometer map expansion.

After sorting out and sealing all the information gathered by the mission, Fang Di handed the small bag containing all the information to Qianshan.

"What are you doing for me?" Qianshan wondered.

Fang Di sighed helplessly: "Because you are the most powerful existence in the team, these things are much safer on you than on me and Shanshan, you don't want these things to be lost here, right?" ”

Thinking about it, Qianshan took the thing and put it in the safest pocket on his body, sealed it and patted it: "Then I'll help take it, remember to ask me when I go back." ”

"Don't worry, I can't forget it." Fang Di smiled, "Okay, now that the task on our side is completed, we can leave at any time." ”

"This mission is fortunate to have a thousand mountains, and it is many times smoother than expected, but unfortunately, no power stones have been found." Chu Shanshan said.

"What kind of power stone can't measure the stone, let's go, we should go too, I feel that this protective suit on my body is slow, I have been bitten through several holes here in the past two days, go back first, at least I have to change a set of equipment first, change a suitable weapon." Qianshan said.

"Okay, then let's go back directly, what about the cave?" Chu Shanshan asked.

Fang Di looked at the thousand mountains.

Qianshan asked, "By the way?" ”

"By the way." Fang Di replied, "When I go back, I can just pass near the cave area, and the cave is in the area where it enters the mountain of the grassland. ”

"Okay, let's stop by and have a look then, and we won't have to run again."

"Okay, then let's find a place to rest for a while, then get back to where we came, and start the journey back."

Fang Di took the map in his hand and drew it, and then the three of them found a relatively quiet and safe place to rest......

There is no map available, and there is no positioning device, so if you want to go back, you have to go back to where you came from, and follow the original route, which is the safest way to go.

If they went straight back from their current location, they would probably lose their way in this area, after all, they had also traveled a long way along the edge of the green swamp in the three days of expanding the map.

After not much rest, it was dark, so the three of them set up a simple tent in place for the night, and the next morning, the three of them began to return.

Qianshan didn't look at the surrounding plants carefully when he came all the way, but now that the task is completed, the mood is relaxed, so the three of them are not in a hurry to go back a day or two in advance, so on the way, Qianshan has enough time to pay attention to the various plants around him.

Actually, Fang Di is also quite strange, before he came, Qianshan couldn't even recognize ginseng, and after he came here, he became like he knew everything, but he didn't ask, maybe he really didn't know ginseng.

Along the way, Qianshan would squat on the edge of a plant from time to time to take a second look, but basically he would not collect it by hand.

The reasons for not collecting are very simple, one is that the value is very low, the second is that it is also available on the earth, and the third is that it is very common.

If you meet a very rare Qianshan, you will naturally not be stupid enough to leave it alone, even if you don't need it at the moment, you will take it with you.

It's a pity that very rare medicinal materials can basically be regarded as heavenly and earthly treasures or pseudo-heavenly and earthly treasures, which are so easy to meet.

In a few days, the three of them crossed the grassland all the way back to the vicinity of the high mountain.

Fang Di unfolded the map and looked at it, pointed to the side and said, "Go over there, it will take about half a day to get to the place." ”

Qianshan nodded: "Let's go, go over and have a look." ”

The journey was smooth, and it was many times easier than when I went back without even encountering a large beast.

At the same time, Qianshan also found a lot of medicinal materials, but he only moved three times along the way, and collected three very high medicinal materials, all of which can be used in medicinal baths.

Half a day later, the three of them came to the foot of a hill that was not very high, and the cave was halfway up the hill.

"Here we are." Chu Shanshan pointed to a cave halfway up the mountain, which was only more than half a person high.

The mountain was not high or steep, and the three of them quickly climbed to the edge of the cave entrance.

Fang Di looked inside, "There shouldn't be anyone else coming, the stones we put are fine, they haven't been moved." ”

Chu Shanshan also followed and looked inside, "It's true." ”

Qianshan looked inside and saw that there were several stones in the middle of the entrance to the cave, and Fang Flute lightly touched those stones with his weapon, and the stones immediately fell to the side.

"It's really a lot of consideration, so it seems that there shouldn't even be beasts or anything like that." Qianshan said.

"Looks like yes, that's for the best." Fang Di nodded, and then untied his safety rope and fixed it to the boulder on one side, "I'll take the lead." ”

Qianshan immediately stopped him and waved his hand: "As always, it's better for me to go first, you and I will be behind me, if there is something to pay attention to, you tell me, in case there is a danger, I am not afraid." ”

Chu Shanshan nodded: "Qianshan is much more powerful than the two of us, in case there is a snake or something, he is not afraid, he can't bite at all." ”

In the past few days, the two of them have seen the power of Qianshan, not to mention that ordinary snakes are not dangerous to him, even larger beasts can't bite his arms and legs.

However, Chu Shanshan also pinched Qianshan's arm and found that it was not very different from theirs, of course, she knew that Qianshan must have done it on purpose, and the cultivator was a cultivator, much stronger than the two of them.

Qianshan smiled, fixed his safety rope, and then took the lead into the cave, Fang Di followed, and Chu Shanshan observed the situation outside before he followed in.

The entrance to the cave is small, but once inside, it is much more spacious.

After entering, Qianshan found that the entire belly of this hill was basically empty, and there was light streaming through the top, plus there were a lot of crystals in the cave, so the light in the belly of the mountain was not dark, and you could see the surrounding situation clearly.

"The last time you came here was just to find a crystal for someone else?" Qianshan looked at the crystals around him, and couldn't help but secretly say, a lot!

Around, under the feet, above the head, there are translucent crystals everywhere, which look fluorescent and shiny, very beautiful, and not only one color, it is like entering a crystal palace, like a dream.

"What a beautiful place!" Qianshan couldn't help but sigh.

Chu Shanshan smiled: "Yes, it's beautiful!" When you walk for a while, you just find a nice crystal and take it with you, it's very heavy, but it's not very valuable. ”

Indeed, the value of the crystal is average, but the better quality is also quite valuable, but there is no means of transportation here, otherwise it can make a windfall if you take it out.

However, in Qianshan's opinion, it is better not to destroy such a magical place, and I hope it can exist here forever.

Follow the cave into the belly of the mountain, in which there is a slightly wider road, but it is not very long, only a few tens of meters.

Fang Di pointed to a position on the right and said, "Over there, be careful, it's dark down there, it's a hollow." ”

Qianshan nodded, and walked in the direction he was pointing.

With a safety rope on your body, you don't need to worry too much.

Slowly came to the corner of the wall on one side, and a gap appeared in the ground on this side, about five meters in diameter, and when you looked down, in addition to the crystals that were still numerous, you could see a touch of purple in the center of the bottom.

This pit should be quite deep, the last time Fang Di and Chu Shanshan came over, they only discovered its existence, but they didn't dare to go down directly, because the lighting tools were not prepared, and it was very dangerous to go down.

If there is an unknown beast hidden underneath, it will be equivalent to a sheep falling into the mouth of a tiger and sending it to death.

After looking at it for a long time, Qianshan scratched his head and turned around and said: "It's not a way to look at it this way, it's okay to go down and look at it in general, but first we need lighting." ”

"Go out and get two torches?" Fang Di asked.

Qianshan nodded: "It's necessary, let's put down a torch first, see if there is oxygen below, and also see what kind of environment it is down here, if the torch is put down and extinguished directly, we can go directly, if we can't go down, at least not now." ”

Chu Shanshan responded: "Let's go, let's go out together, it may not be safe to stay here alone." ”

While speaking, the three of them came out of the cave.

Although they had no lighting tools, making torches was fairly straightforward, and each of them had portable fire-making equipment on top of their protective suits, including a small bag of long-lasting fire oil and a piece of tarpaulin.

Chiyama found two sticks and began to make torches.

While doing it, Qianshan asked: "Don't I remember that in ancient times, there was a thing called a fire fold, and there was a thing like a pen holder, just pull it out and blow it twice?" No matter how bad the cold fireworks are, it should be possible to bring them in, right? Why not do something? ”

"Cold fireworks can't work, the process of transferring space-time nodes will be natural, someone has already tried it." Chu Shanshan said: "As for the fire excerpt you said, I really don't know what it is. ”

"There are also fire folds, but they are still a little short of our portable fire device, and they are not durable, and the portability is small, and the effect is almost the same." Fang Di explained.

Qianshan thought about it too, "What about the old-fashioned clamshell lighter?" This thing at least lit up...... Well, it doesn't seem to be very convenient either. “

Fang Di laughed: "What you can think of has already been thought of, they will try all kinds of ways in order to make money, and now the equipment we hold is relatively advanced." ”

Between words, two torches! Vinegar - slip literature is released the fastest! It has been made, and the torch does not use too much special oil, but adds some according to the instructions of the square flute, saying that it is enough to maintain the torch for about an hour.

Qianshan was slightly embarrassed: "It's that I'm thinking too much, let's go, let's go in." ”

Chu Shanshan took out a slender rope from her waist, tied it to one end of the torch, and then handed the rest to Qianshan: "Take the other end of the rope purple, put it down for a while, if you are pulled by something, you let go immediately, so as not to be dragged down, this kind of rope is very strong, don't tie it to your hands." ”

"Understood."

Qianshan responded, and Fang Di returned to the cave again with a torch, while Chu Shanshan stayed at the entrance of the cave this time to be on guard.

Returning to the edge of the gray cave, Qianshan looked down, turned back to Fang Di and said, "You can stand back, I'll come." ”

"Then be careful." Fang Di turned around and returned to the center of the mountain, paying attention to the situation around him.

Qianshan shook off the rope, then began to put the torch down little by little, and the scene in the cave began to come into view little by little.

The rope is a specialty, and the oil is also a specialty, and occasionally when the fire burns the rope, it will not pose a threat to the rope, let alone burn the stick, which is very convenient.

As the torches were lowered little by little, Qianshan was surprised to find that this cave with a diameter of five meters was actually straight up and down, and the walls of the cave were surrounded by crystals of different shapes.

At first, it was completely transparent, and after a little lower, it was pink crystal, then red crystal, then turquoise, until it was more than ten meters under, and it was already difficult to distinguish the color of the crystal under the firelight.

The rope continued to be lowered, and the torch was still not extinguished, indicating that there was oxygen underneath, otherwise the torch would have been extinguished long ago.

After dropping down another five meters or so, the space below seemed to expand suddenly, and the firelight could no longer reflect the surrounding cave walls, and Qianshan was also keenly aware of this.

Continuing to loosen the rope, the torch slowly fell, and gradually Qianshan saw that the torch fell to the ground, and there were crystal-like things of different sizes around him.

Qianshan took out the binoculars on his body, looked down, and immediately took a breath.

"Shhhh

"What's wrong?" Fang Di walked over.

Qianshan handed the telescope to Fang Flute, pulled the safety rope behind his back with one hand and said, "Be careful, look down, the torch is still burning." ”

Fang Di stepped forward, squatted cautiously on the side, looked down, and was immediately surprised: "What a big crystal, it looks like a crystal forest, it's so spectacular...... Ay? The space down there seems to be a lot of space, and you pull the torch up a bit. ”

Qianshan pulled up the torch and illuminated the surroundings a little.

Fang Di took a closer look and exclaimed, "It is indeed an underground space, and there is a lot of water underneath...... Depend on! There really are power stones! So much! ”

As he spoke, Fang Di handed the telescope to Qianshan, stretched out his hand to help him carry the torch, pointed to the bottom and said, "Look, a little bit on the right." ”

Qianshan took the telescope and looked down for a moment, and sure enough, he found a pile of purple glowing stones next to a huge crystal pillar.

The surface of these stones is shrouded in a layer of lilac, emitting a faint purple light, which looks beautiful and mysterious.

"Is this a power stone?" Qianshan asked.

"That's right!"
