This cave is more distinctive, the current distance is like a gourd mouth, the more inside, the opening, it seems to be smaller.

The four of them cautiously continued to walk inside.

"Extinguish the flashlight and light the torch!"

The space has become a lot smaller, Song Shan pondered for a moment, and said in a low voice.

The force of the torch is not only to illuminate, but also to test the oxygen in the air, if there is not enough oxygen, the torch will easily go out, which is equivalent to telling them that they can't go inside.

Even if Song Shan's physique has been tempered countless times by the Origin Ding, it is impossible for him to survive in an environment without oxygen, and he will die directly if he is suffocated.

This is very important.

"Good!"

They came down this time, but they were well prepared, and in addition to eating and drinking, the backpack was like a treasure chest, and many tools were available.

A torch was lit, and the light of the fire illuminated the cave, and the road ahead became brighter.

"Inside, it seems that the space is getting smaller and smaller!"

Xu Shaowu said in a low voice: "The space between the top and bottom is only less than two meters, if it is a little shorter, I'm afraid we will have to climb over!"

"Walk inside for another hour, and if there is no harvest, we will withdraw!"

Song Shan gritted his teeth, the increasingly dangerous environment made him have to become sensible.

"Hmm!"

The four of them nodded, they had never been afraid of them on the battlefield, and naturally they would not be afraid of this environment, but they were just unnecessary sacrifices, and naturally they did not need to be persistent.

After ten minutes of walking, suddenly, something was squirming on the ground.

"What's that?"

Lao Qi was the first to find out, and hurriedly took a few steps back.

"Ants like?"

Xu Shaowu looked at it and swallowed a mouthful of saliva.

"Boss, your ants are so big!" Zuo Sen glanced at it and shivered a little.

The group of crawling animals in front of him, the small ones at least had their thumbs laughing, and the largest ones could even be comparable to half a fist, who was so big with ants.

"Ants indeed!"

Song Shan squinted, a scorching light flashed in his eyes, and said: "This kind of ant is a very magical ant, in the legend, from the underworld, the royal family of the Hades ant, the ant among the ants, should have been extinct a long time ago, but I didn't expect it to appear here!"

"They're blocking the road in front now, what are we going to do?"

Xu Shaowu asked in a low voice.

On the road ahead, groups of ants lined up in groups, as if a team was arrayed, blocking their way forward.

"Can't disturb them!"

Song Shan thought for a while and said: "This kind of ant has a very strong attack power, once it is alarmed, they will attack wildly, one or two is no problem, three or five is no problem, and even dozens of ants are easy to deal with, but a swarm of swarms up, thousands of them, we may not even be able to escape!"

"And now turn back?"

Zuo Sen asked Song Shan tentatively.

"No way!"

Song Shan shook his head and said: "There is also a legend that where there are Hades ants, there will be heart washing grass, and the heart washing grass can only be raised by the side of the yellow spring water, so we are not far from the yellow spring water, and it may be ahead!"

The Pluto ant itself is a heart-washing plant, a companion animal, and the premise of the existence of this ant is that there must be a heart-washing plant.

And the heart-washing grass can only grow by irrigation with yellow spring water.

Any wild heartgrass must grow next to the Yellow Spring.

"Just give up, I'm not reconciled!"

Song Shan thought for a while: "You stay here, I want to find a way to get over!"

"No way!"

Xu Shaowu immediately objected: "Boss, we came in to protect you, not to stand here and watch you go on an adventure, either go back together or go over together!"

"Old Xu?"

Song Shan frowned, he said that he wanted to go over, so he naturally did it with confidence.

"Boss, I know you have the ability, but you also have to give us a chance to be worthy of your salary!" Xu Shaowu was very persistent.

"Okay!"

Song Shan was helpless, he knew that if he was just alone, he would definitely not be able to move, so he had to say: "On the ground, we can't walk, now we can find a way to pass through the air!"

"Is this okay?"

Xu Shaowu's eyes lit up.

"Old Seven, you took out the crossbow!"

"Good!"

"Zuo Sen, to make a hook, you must accurately settle on the ground and connect the two sides!"

"Hmm!"

Xu Shaowu, as a special soldier, is extremely first-class in terms of survival ability in the field or penetration ability.

It only took fifteen minutes before and after, and it was ready.

Zuo Sen picked up the crossbow in his hand, and behind the crossbow arrow, there was a rope, which was a special arrow, once the arrow entered the wall, a hook would burst out from inside, hooking the wall tightly.

"That direction!"

Xu Shaowu used a strong light flashlight to shine it, pointed to the stone wall of a cave in front of him, and said: "You must hit it, otherwise you can't hook it, it won't matter!"

"Hmm!"

Zuo Sen took aim, this is his best job, and he naturally can't go wrong.

Shout!

A sharp arrow, with a rope, leaped out, and with a bang, it pierced through the stone wall at least thirty meters in front of it.

Zuo Sen quickly tied the other end of the rope to find something tight.

They tried to pull it, and Zuo Sen said: "Boss, it's not very stable, I suspect that the rock on the opposite side is not very strong, and it will easily collapse that arrow!"

The two ends are connected, like a rope across the middle, which needs to be fixed on both sides in a position, and now they can't be very sure that the opposite side is stable.

"What are the chances?"

"Twenty percent!" Zuo Sen assessed and said.

"Boss, this rope can indeed slide through, but there is at least a twenty percent chance that it will fall!" Xu Shaowu said to Song Shan in a low voice: "It's more dangerous!"

"On the contrary, there is an 80% chance that it will pass safely!"

Song Shan thought for a while and said, "Pass!"

He didn't want to give up the opportunity, so he could only take risks, but he didn't just rely on two brave words in his heart, he also needed to have a plan.

"These pills, a bottle of detoxification, a bottle of miasma, if it doesn't work, first you have to eat the antidote pill, and then crush the obstacle avoidance pill and sprinkle it on your body!"

Song Shan said instructively.

Hades ants are not easy to deal with, this is still a highly poisonous thing, an ant is not very toxic, but if it is bitten by a group of ants, without timely treatment, it will die immediately.

"Remember, you can't take any chances, if you can't, go back, I'm sure I'll be able to get over on my own!"

Song Shan instructed again.

"Yes!"

The three of them looked at each other and nodded.

Xu Shaowu finally began to arrange: "Zuo Sen stays, let's go over, Zuo Sen, you have to fix the rope here, this is our way out!"

"Understood!"

Zuo Sen retired for a short time, and subconsciously performed a military salute, in the army, an order is an order, which cannot be refuted.

"Old Seven, you go first, I'll break later!"

Xu Shaowu continued.

"Yes, Boss!"

Lao Qi hung the hook on the rope directly at once, and slowly slipped towards the inside along the rope, one high and one low on both sides, but the rope was tilted in the direction of the inside, which made them not very laborious.

In order to ensure that he did not anger the Hades ants under his feet, Lao Qi was also very careful to crawl along the rope, and did not dare to relax at all.

It took a full ten minutes for him to land on the opposite side.

"Boss, it's safe here for the time being!"

He didn't dare to respond too loudly, for fear that he would shout and alarm the surrounding ants, so he had to take out the walkie-talkie in his backpack and said in a low voice.

"Then you put the sling and continue to fix it!" Xu Shaowu also said on the walkie-talkie.

"Good!"

Lao Qi began to fix the mouth of the hanging rope on the opposite side.

"Boss, you go up, face down, just like climbing a tree, just climb over at once, just do it!"

Xu Shaowu carefully said the preparatory action.

Song Shan took a deep breath, hung the hook up, and then crawled inside along the rope with both hands and feet.

Although he is not as agile as Xu Shaowu, he is not bad in terms of physical fitness, and he is quite fast, and it took more than ten minutes to climb to the opposite side.

Zuo Sen stayed to answer, so Xu Shaowu was left.

Xu Shaowu climbed on the hanging rope, crawling, crawling, and soon crawled to the middle, he glanced down, and there was a little scary to see, the giant ants, swarming, made him shudder.

He took a deep breath and was about to continue climbing, but at this moment, suddenly a small ant came out of nowhere and climbed on the rope.

Immediately after, two, three, uncountable ants climbed onto the rope.

"Not good!"

Everyone's pupils changed color.

"Lao Xu, let go!"

Song Shan let out a low snort.

Xu Shaowu reacted quickly and let go directly, otherwise he would have been bitten by ants at this time, but as soon as he let go, he would have fallen into the ant nest below.

At a height of about 1.5 meters, you can stand up, and you will definitely not be able to fall if you fall, but if you fall into an ant nest, it is inevitable.

Xu Shaowu stepped on it and killed several ants, but a group of ants rushed up frantically, he jumped directly, and between jumps, he ate the antidote pill, and also crushed the miasma pill.

The smell was originally designed to restrain snakes, insects, rats and ants.

The giant ants around it were pushed away at once, forming a vacuum belt within a radius of about thirty miles, although Xu Shaowu avoided it thrillingly.

But it can be regarded as trapped, not back and forth, the previous rope has been bitten off by a group of ants, and it can't be used at all.

"Seventh, go on!"

said that it was slow at this time, and it was fast at this time, Zuo Sen reacted the fastest, he directly took out a bundle of ropes, threw it hard, and Lao Qi followed it easily.

Pulling on both sides, a new lanyard was quickly formed.

"Boss, quick!"

Xu Shaowu's eyes lit up, he jumped up directly, hit it with his strength, and with the help of the pulley, he smoothly rushed into his mouth.

"Whew!"

At this moment, he breathed a sigh of relief, this level was over, and he patted his chest: "It's so thrilling!"

Song Shan smiled bitterly, fortunately Xu Shaowu was fine, otherwise he would have felt a little guilty.

Zuo Sen and Lao Qi, the two of them got the new sling rope right, and sprinkled a set of medicinal powder on the rope, although these medicinal powders, although they can't prevent ants, but they are also disgusted by ants and can avoid ants.

At this time, Song Shan glanced around.

What catches the eye is a piece of grass, a dense patch of grass.

He was right.

Where there are Pluto ants, there will definitely be heart-washing grass.

"This is a baby!"

Although he came to find Huangquan water, it was a stroke of luck to meet a treasure like heartwashing grass, and naturally he couldn't miss it.

He carefully dug out a few plants, sealed them, and put them in his backpack, but in fact, they had already thrown them into the origin space while Xu Shaowu and Lao Qi were not paying attention.

The transplantation conditions of this kind of heartwash grass are harsh, and it must be re-established in the shortest possible time, otherwise it will wither, and it is the most difficult grass to plant.

"Boss, is this grass very precious?"

Lao Qi looked at Song Shan's cautious appearance and couldn't help but ask.

"Of course baby!"

Song Shan said: "Have you ever heard of Meng Po soup?"

"This is a Chinese person, have you heard of it!"

"It is rumored that Meng Po soup is made from this thing!" Song Shan smiled.

"No, it won't!"

Xu Shaowu swallowed a few mouthfuls of saliva.

"It's just a legend, I don't know if there is a legend or not, so whether it's or not, I don't know, but the emptiness doesn't come to the wind, sometimes, the legend of this kind of thing, it depends on how you look at it!"

Song Shan analyzed: "When you believe, then it exists, when you don't believe it, maybe he is fictional!"

There is no answer to this question at present, even he can't figure it out for himself, what happened to him is very bizarre, yes, but the world has not changed.

Maybe he didn't understand the world thoroughly.

Anyway, in the worldview, it is difficult to have a myth.

"Aside from the legend, this heartwashing grass is also an ancient plant, the force is not small, it can stabilize the heart, enhance the heart's beating power, for some people with heart disease, it is a life-saving medicine, you say it is worth it!"

Song Shan said.

"That's really valuable!" Old Qi's eyes brightened, and he said, "Then let's dig up this piece back!"

"It's too much!"

Song Shan shook his head: "And even if I take it all back, there won't be much, as long as I can cultivate it myself, I will have as much as I want!"

After putting away the heart-washing grass, Song Shan began to do business: "Look around, there should be a water source, the yellow spring water must be around here, look carefully!"

"Good!"

Xu Shaowu and Lao Qi nodded.

They went along the grass of the heart-washing grass and looked carefully at the ground.

Yellow spring water was not found.

But Song Shan found many, many unique plants, which was an eye-opener for him.

"Scarlet Begonia Flowers!"

"Yin Qi Lily!"

“......”

These kinds of plants, according to the records, should be plants that live in the underworld, they do not need sunlight, only need to be shrouded in cloudy air, they can grow.

This made Song Shan even more sure that there might be a yellow spring in this vicinity, and without the moisture of the yellow spring water, it would be impossible to grow so many plants in the underworld.

Song Shan was not welcome, each unique plant had a very strong research value, and he directly transplanted them into his origin world.

"Boss, Huangquan Water has been found!"

A cry reverberated in the dark space.
