"You're leaving?" Cheng Lin was stunned.

The Great Sword Master smiled bitterly: "Yes, the people on the ship came once yesterday to report the situation, the food on the ship is bottoming out, and it can't be replenished near the island, so many people, we have to return to the shore and replenish the food." ”

"Can't let them go on their own?"

"The fog outside this fairy island is extremely strange, which can make the fairy island disappear in hiding, and once the fleet leaves, it will be difficult to find it again, and ...... The most critical point is...... It is also close to the return time agreed by His Majesty the Emperor, if you don't return...... The relatives of the entire fleet will face the great crime of exterminating the Nine Clans......"

Yu Fu shook his head and said in a low voice: "So, no matter what, we can only leave." ”

Cheng Lin was silent.

So it seems that they really can't wait any longer.

Moreover, according to the current progress, I want to wait for the fairy sword to be born, I don't know what year or month.

Especially...... According to the experience summarized so far, it seems that everyone can only obtain one spell when it comes to obtaining spells, at least, Yu Fu and the Great Sword Master have only obtained one spell during this time.

In other words, if they continue to decipher, they will no longer be able to obtain anything, even if they wait for the immortal sword to be born, with Cheng Lin here, there is probably nothing to do with them.

In a sense, they should have left three months ago.

"I'll send you away."

Cheng Lin said.

"Okay."

Yu Fu did not refuse, and several people came to the beach again.

"You're going to stay and decipher?" Yu Fu looked at Cheng Lin, hesitated, and said, "According to our current progress, the three of us are still so struggling, only your own words remain...... I'm afraid it's even more difficult, I know you have a lot of secrets, but it's probably not easy to solve the puzzle of opening immortals, or you leave with us? When I return to the national capital, I will play your majesty, and when the time comes, I will gather all the imperial scholars and come here again, and maybe I will succeed. ”

Cheng Lin shook his head and just said, "I'll stay here and continue." ”

"In that case...... Take care. ”

Yu Fu didn't say anything more, turned around and got on the boat, stood on the deck, waved his hand at Cheng Lin with the great sword master, and then pulled up the sails, and the keel ship slowly withdrew from the white mist and disappeared into Cheng Lin's field of vision.

Cheng Lin waved his hand quietly and said goodbye to them.

After three months of living together, they are already friends.

So Cheng Lin didn't force them to stay.

When the big ship disappeared completely, Cheng Lin put down his hand, and then turned to look at the silent island.

"Now, I'm alone."

He muttered, went straight back to the mountain behind the sect, next to the island in the middle of the lake, sat on the dirt floor, and continued to start the decipherment work.

There were two fewer people, and at first, Cheng Lin was a little unaccustomed to it, but soon, he got used to it.

Loneliness wasn't too foreign to him.

It's just that this time the loneliness is a little thorough.

……

The sun rises and the moon sets.

Another month passed.

Cheng Lin's decipherment got bogged down.

The absence of two people is not simply a two-thirds reduction in the speed of decipherment.

Deciphering by a single person, the lack of communication and communication, the impact is huge.

Cheng Lin was not lazy, and meditated on the island in the lake every day, but the effect was not optimistic.

For a whole month.

It was only then that he pushed the progress from 54% to 56%.

There is certainly a reason why there are fewer people, but there is also another more important factor, that is, the further you go, the more difficult it is to capture the law of field flickering.

Cheng Lin had no assistance, so he could only rely on his own brain and use branches to mark and calculate on the ground.

And there is no effective way to decipher, all that can be done is continuous trial and error, at first he still relied on a hard work to support, but slowly, he finally and inevitably relaxed.

It's not lazy, but reason clearly sends him a signal:

"It's just an impossible task."

After another failed attempt, Cheng Lin withdrew his hand from the immortal stone, watched the field inside light and extinguished, and said.

There was no frustration or madness on his face, just a calm and earnest recounting of the fact.

"I can still use 2% in a month now, but the further I go, the slower it will be, and in the end, when my brain and computing speed reach the ceiling, the time spent will become useless, just like asking an ancient man with only an abacus to calculate pi, even if he tries his life's energy, it is limited after all, and it is not even as good as the number of digits calculated by a supercomputer in minutes."

"So, it's not a question of effort or not, it's a problem that is beyond my ability."

Cheng Lin's tone was firm and serious, there was no one else on the island, and the remnant souls of the He Immortals were not considered human, so he said these words to the deduction program.

He didn't understand what was going on this time.

According to past experience, the difficulty of the tasks given in the deduction is basically very low, or in other words, when facing those tasks that are beyond his ability, the program will help him, such as giving him an artifact to split the river in the flood world, and giving him a magic skill to make hundreds of millions of cold soil bloom.

But this time was different.

More than four months have passed since the deduction time, and the deduction program still does not give him any additional help or hints.

Just gave him a basically impossible task.

Cheng Lin's reason told him that it was pointless to persevere, and it had no other effect than to drag down his spirit.

Yes, he is more comfortable with solitude than others, but it is also limited, if he wants to decipher this island for a few years, ten years...... Cheng Lin was not sure if he would have a nervous breakdown and commit suicide.

This is highly likely.

So......

"I admit defeat, whether it is judged that I failed in the mission, or whether I failed in this deduction, it is okay, let's end it."

Cheng Lin said.

This is the first time he has taken the initiative to ask for the end of the deduction, and he is very unwilling, after all, he has already put so much effort into it, and it has never been Cheng Lin's habit to give up halfway, but the problem is that it is not courage to do it knowing that it cannot be done, but stupidity.

Instead of dragging it out, it's better to admit defeat.

[After careful thinking, you feel that you can't complete the puzzle of the He Immortals, and you have the intention of giving up, but once you give up, your previous efforts will be in vain]

Information comes to mind.

Cheng Lin was unmoved: "I choose to give up." ”

[You still insist, but when you think about it, you always feel that you may have missed something, and you decide to think carefully about the whole process of deduction, maybe a certain detail hides the key to solving the puzzle]

“？！”

Cheng Lin was taken aback.

What does this mean?

Remind? Prompt?

This couldn't be more obvious, Cheng Linxin said Do you want to give me a hint as for being so obscure?

Then he suddenly became annoyed: "So, there is a hint here?" Why didn't you tell me sooner? It took me four months of hard work to say?! ”

[You didn't ask before]

Cheng Lin: "......"

"Click."

The green tendons in his hands floated up, breaking the bare broken tree next to him, as if only in this way could he vent the depression in his heart.

Ahh

What is this called!!

Cheng Lin suddenly broke out of anger, it was all right!

Four months!

It's been four months of hard work, but now you told me there was a shortcut, and I didn't say it before because I didn't ask......

Cheng Lin's body trembled, he looked up at the sky, took a deep breath, and it took a long time before he finally suppressed the collapse in his heart.

"Calm down! Be calm! ”

Cheng Lin kept hypnotizing himself, after all, he was in the deduction, and it was useless for him to be angry on the territory of the program, at this moment, he suddenly understood the mentality of Yu Fu and the Great Sword Master facing him before, it was exactly the same!

People are under the eaves and have to bow their heads!

Cheng Lin was angry, but fortunately, he finally calmed down quickly.

At this point, nothing else matters, the key is how to find the "key" to solve the puzzle.

"Keys? Detail? Sort out the whole deduction? ”

Cheng Lin forced himself to calm down, sat cross-legged on the ground, and began to recall all the processes of this deduction.

The fog of fairy island?

The pile of broken artifacts you picked up?

Yu Fu and the Great Sword Master?

A broken mountain gate?

The projection of the Hexian people?

……

In the past few months, the scenes of his experience have been fast-forwarded in his mind like a movie, and Cheng Lin has been constantly recalling the whole process and looking for clues, but he has never found anything.

At this time, it was night, and the moonlight penetrated through the mist overhead, shining on the valley.

The night is thick, and the valley is also covered with a rich night.

There was a small fire burning in front of Cheng Lin, and the wood was burned into a red charcoal fire, which was very beautiful.

There are unknown mosquitoes flying around the fire.

The fairy stone above the ancient well exudes a soft glow, which illuminates the nearby island in the middle of the lake and a river, and the scenery is quiet and beautiful.

Cheng Lin only felt that his head was as big as a fight.

Details are the easiest to overlook, and he has no clue for a while.

"Or is it not after landing on Immortal Island at all? According to the number of paths in the program, it is possible to hide the key somewhere, is it a change in the previous tens of thousands of years? Hezhen people soared? Five hundred years? Or go further......"

Cheng Lin muttered, clueless.

He raised his head and subconsciously looked at the sky, his mind spreading to the universe.

It's a pity that the fog covers the sky of Xiandao, so even if the night is good tonight, he can still barely see the vague moon ring, and as for the starlight, it is invisible.

Starlight......

Starlight?

Starlight!

Suddenly, Cheng Lin had a flash of inspiration in his mind and grasped the fleeting inspiration!

His breath tightened suddenly, and the "movie" playing in his head replayed to the very beginning, before the deduction began.

He suddenly got up, took out his phone in his pocket, pressed it, and found that there was no power, he hurriedly jumped up, returned to the safe house, and found a power bank in his backpack.

Fortunately, in the past few months, in order to concentrate on deciphering, he has not played with his mobile phone at all.

The power bank is still powered!

Plugging in the phone, Cheng Lin nervously pressed the boot button, and after entering the desktop, he quickly clicked on the icon of the deduction program!

The moment you enter, the familiar red button is in a gray non-clickable state.

Cheng Lin didn't pay attention to it at all, just stared at the background picture of the software.

That piece, dynamic, constantly moving, with the stars constantly twinkling in the starry sky!

Raising his head, he compared it to the flickering aura field on the fairy stone.

Cheng Lin was silent for a long time, and suddenly looked up to the sky and sighed.

This prompts...... It's too deep, isn't it......"
