don't open your eyes [unlimited]

It was this light that stopped Ling Su and Zhuang Die from leaving.

"Isn't it "Divine Comedy"?" Song Huaimin walked over, "Dante's time, there should be no such technology."

He leaned on the periscope and tried to look in, but he could only see a black patch, and he shook his head slightly to meet Ling Su's gaze, and stepped back.

"Dante lived at the end of the thirteenth century, and the modern periscope was invented at the beginning of the twentieth century." Ling Su thought for a while, "Although there were similar devices in ancient my country during the Western Han Dynasty, the precision of this thing is at least in the After the second industrial revolution."

Zhuang Die quickly took out his small notebook and took notes with his headlamp.

Although this is not the first time he has seen Ling Su's knowledge base, Song Huaimin still couldn't help feeling: "How do you keep so many things in your mind..."

Ling Su rubbed the tip of his nose and smiled. He was about to say a few words of habitual modesty when he caught Zhuang Die's gaze and uncontrollably opened his screen: "It's actually very simple."

Song Huaimin's complexion changed suddenly, and he rushed over to separate Zhuang Die from him, but he was still a step too late, and took out the earplugs regretfully.

It is inconvenient to take notes here, Zhuang Die directly took out the recorder: "Why is it so simple?"

"Dante is one of the three giants of the Renaissance and an important pioneer of the Renaissance. Remember that the Renaissance is from the 14th to the 17th centuries. It is very easy to judge the years in which a bunch of great writers and artists lived."

Ling Su explained enthusiastically: "As for the periscope, its upgrade is destined to be accompanied by war. Just remember the time of the two modern world wars."

The time of ebb tide is limited, Ling Su didn't stop wasting time.After carefully observing the periscope buried in the rock wall, he continued to pick up the flashlight and walk ahead to lead the way.

"If you still work as a kindergarten teaching assistant in the future, you can tell the children about "Huainan Wanbi Shu". Remember this book by remembering Liu An, the king of Huainan. Liu An is the one who 'one person attains the Tao and ascends to heaven'."

Ling Su kept an eye on the surrounding environment at all times, and continued to tell Zhuang Die: "Although Liu An himself intended to cultivate immortality, he accidentally turned himself and his disciples into physicists and chemists. There are prototypes of periscopes in the book, and also Proposed artificial ice making, ice penetration to make fire, magnet repelling, wet copper smelting..."

Zhuang Die himself also likes to read books, but he just memorizes them all in one go, and searches them one by one when he uses them, which is a bit of a waste of time.

It was the first time he heard Ling Su's method, and he was very interested: "Just like reasoning, as long as you remember one, you can remember a whole bunch."

Finally finding someone willing to listen to his ramblings, Ling Su nodded happily: "That's it, actually—"

Zhuang Difei quickly applied what he learned: "As long as I remember you, I can remember everything related to you."

Ling Su stopped suddenly.

Song Huaimin was walking forward with his ears covered, when he realized that the person in front stopped suddenly, he was startled: "What's going on? Is there something wrong?!"

"...No." Ling Su waved his hand after a while, cleared his throat, and smiled, "Yes."

The latter word was addressed to Zhuang Die, Ling Su couldn't help raising his hand, and rubbed the little curly hair that was close at hand twice.

Ling Su looked directly into Zhuang Die's eyes, and answered seriously, "Yes."

Zhuang Die also felt that he had summed up this sentence very well, so he opened his notebook and wrote it down, and continued to follow Ling Su without stopping.

Song Huaimin walked for a while and took off his earplugs, only to realize that Ling Su was too quiet.

Zhuang Die kept his head buried in whispers all the way, he was trying to connect the things he had memorized with Ling Su's method, immersed in his memory palace and had a great time.

One of his hands was honestly held by Ling Su. Although it was a bit difficult to walk on the increasingly narrow road, the risk of stepping on stones and falling was completely eliminated.

Ling Su circled Zhuang Die's wrist with one hand, and while giving a reminder as usual, he carefully led Zhuang Die around all the uneven areas.

Holding a flashlight and walking alone at the end, Vice Captain Song was silent for a while, put his hands in his pockets, and shut his mouth firmly.

The vice-captain turned up his collar coldly, dispelling the meaningless thought of "Should I care about Ling Su?" that popped up suddenly.

……

After discovering the periscope, the trio focused more on the cliff face.

The fog on the sea was getting thicker and thicker, and the distance that the light of the flashlight could travel was significantly shorter than before. However, after careful observation, several people still found many traces that should not belong to this small island itself.

There are broken pieces of iron sheet in the crevices of the rocks, rusty iron brazing pokes out in the shadows, and a small piece of degummed wire is hidden in the sparse weeds.

As an experienced guide, Ling Su led Zhuang Die steadily all the way, but he tripped and fell face down on the ground, and even found a nearly complete anchor chain.

Startled by Ling Su's fall on the ground, Song Huaimin hurried over: "Does it matter?"

"It's okay." Zhuang Die pulled Ling Su in time, and stabilized his body with one hand on the ground, "Looking at it this way, there really was a submarine here."

The reason why he was tripped was not entirely Lingsu's own problem - no one would have imagined that there would be a huge iron chain protruding across the ground on the edge of this dark island.

The lighting devices of the three were mainly based on the rock wall beside them, and Ling Su walked in the front, and he was firmly hit by the trick.

"It's completely rusted to death." Ling Su tried to shake the giant iron chain, but found that it couldn't move at all, "One end is fixed in the sea..."

He straightened up and took a complete photo along the iron chain with a flashlight.

The rusty steel giant was silent in the night, as if growing directly from the stone wall in front, extending all the way into the cold sea water, and disappearing into the unknown depths.

"It's not just it." Song Huaimin actually wanted to ask just now, "If we go on further, we will soon extend into the sea, right?"

The road under the feet of several people became more and more slippery. In many places, water could emerge as soon as they stepped on it, and occasionally there were waves crashing up.

Although the place where the flashlight can shine is still land, but if you continue to walk, I am afraid that it will not be long before the road ahead will be completely submerged by sea water.

Ling Su pondered for a moment, then looked at Zhuang Die: "How far have we traveled?"

"It's not easy to walk here. My stride is 55 centimeters." Zhuang Die thought for a while, "After discovering the periscope, we walked 790 seven steps, which is 980 eight meters rounded up."

Behind a few people, the way they came was hidden in the thicker fog, and there was something vaguely whimpering in the wind that seemed to come from the bottom of the sea.

"Do you want to walk a little longer? Just walk faster when you go back." Song Huaimin guessed what Ling Su was thinking, "Do you want to take this road because you think there is something on this road?"

Ling Su simply shook his head: "It's because I don't think I can find anything on this road."

Song Huaimin's eyes widened, he almost suspected that he had heard wrong: "Huh?"

Under Zhuang Die's comparison, Ling Su has gradually begun to have a clear understanding of his luck and character.He waved his hand with mixed feelings, and sighed vicissitudes of life: "Old Song, you won't understand this kind of thing..."

It's useless to talk about this kind of thing, Ling Su stretched out his hand to test the depth of the water, and then looked at the rock wall beside him.

In the case of a serious lack of reference objects and the fact that the sea surface is almost integrated with the thick fog and cannot be leveled, they can hardly judge whether the road is gradually descending or the tide has already risen.

If it was the former, they would still have plenty of time—but if it was the latter, it would be risking their lives to go any further.

Not to mention, as they moved forward, their mental power was still being consumed, and up to now they had lost about 10% out of thin air.

Song Huaimin entered the Dream Realm earlier than they did. Even though Ling Su had managed to divert his attention and relax, the current health bar was still not optimistic.

Ling Su shook his head, he stood up, and was about to take the lead and turn back directly, but unexpectedly, a sudden change happened at this moment.

A violent explosion completely broke the silent night on the island.

The sound of the explosion was far away, but at the same time, the dazzling glare was faintly visible here.At the same time as the roar sounded, the howling of some extremely tragic and sharp beasts also shook the entire island.

Song Huaimin's expression sank: "That forest..."

Only the insiders directly under the "cocoon" can cause an explosion of this level-they have access to the core part of the cocoon, and the weapons they carry are far more powerful than the special incident handling team facing the public.

Those two people will cause an explosion in the jungle, indicating that they have encountered enemies that cannot be dealt with by ordinary means.

Ling Su nodded, and quickly pulled Zhuang Die by his side, leaning against the rock wall to listen to the movement on the other side.

Although the explosion was violent, compared with the entire island, the consequences it could cause were not serious—but the fierce beast, whether it was irritated or injured, seemed to have completely fallen into a frenzy.

There is no noise interference, and the thick trees can be clearly heard breaking under the impact, and more directly uprooted.The reef crumbled and rolled, and the terrifying sound was heard along the ground from the other side of the island.

The island was shaking, and the shaking became more and more violent, and it was even difficult to stand still, and gravel began to roll down from above their heads.

Ling Su squatted down, folded his hands as a cushion, and sent Song Huaimin to the high ground first.

The way they came was soon blocked by landslide rocks, and the howls of wild beasts became louder and louder, and the whole island trembled amidst the roars.

Ling Su looked at Zhuang Die, motioning him to imitate Song Huaimin's movements.

Zhuang Die stepped on Ling Su's folded hands. He stood firm and was about to climb up the rock wall when he saw something strange from the corner of his eye.

The long-corroded huge anchor chain, which was as thick as an arm even with the iron ring, suddenly swung up under several degrees of tremendous force, and smashed towards Zhuang Die head-on.

The sea water was lifted high and smashed down fiercely.

……

The expected blow did not land on him.

Zhuang Die opened his eyes, and Ling Su wrapped him in his arms.

There seemed to be an invisible transparent shield around them. This shield forcibly bounced off the iron chain, and also separated the turbulent cold sea water, and even the sound became extremely distant.

Ling Su half-kneeled in front of Zhuang Die, tightly protecting Zhuang Die, his gaze slightly lowered.His expression was unusual, and there was a certain clear indifference in his pupils, which reminded Zhuang Die of the scalpel he always played with.

Ling Su played with the scalpel hand.

The sharp blade danced dexterously between the fingers, overflowing with a little cold light, and was quickly licked clean by the flames...

Zhuang Die came back to his senses and looked at the little flames jumping in front of him.

Ling Su just finished snapping his fingers and was looking at him with a smile.

The waves fell back behind them, Ling Su put his arms on his side, and the two of them were already drenched by the sea water.

In the chilling howling wind, Zhuang Die looked over Ling Su's left shoulder, and found the trace of the anchor chain rolling over the rock wall - if Ling Su didn't throw him down in time, Zhuang Die's position just now was doomed to be destroyed. Hit it right.

Everything just now was like an illusion that appeared and disappeared without warning.

"Little curly hair." Ling Su asked, "You remember the captain, don't you?"

Zhuang Die nodded in his palm.

Ling Su followed suit with a smile. He leaned over to Zhuang Die's forehead, put his hands around the back of Zhuang Die's head, and gently rubbed the wet curly hair on that head.

He maintained this movement for a while before letting go of Zhuang Die and retreating slightly.

"Let's connect the knowledge points, the first thing that Zhuang Die must remember..."

Ling Su looked into Zhuang Die's eyes, and gave him the handful of unquenchable flames: "Captain is super powerful, there is a solution for everything."
