Of the three options, only the third option fits Lin Xun's sneak attack plan.

As for the second option, air combat, Lin Xun speculated that the 'Black Thorn Demon' also has the ability to fly.

If he chooses to fight in the air, the Valkyrie will not be able to attack during the ride, which is equivalent to weakening the output and cutting off an arm.

With this in mind, he gave the Valkyrie the order to attack, and then pressed the third option.

[You raise your staff and recite the incantation......]

['Battle Angel - Valkyrie' pulled out the longbow and chanted a melody, the characters on the surface of the arrow flowed, and the white light flickered......]

[She releases her bowstring, and a white light pierces the darkness, and arrows shoot swiftly towards that little warm light.] 】

[A flash of white light, a howl that resounded through the abyssal ground echoed in your ears.] 】

You pronounce the last syllable of the incantation. 】

[The bright starlight gathers in front of you, and the golden thunder wanders around the starlight......]

[In the blink of an eye, endless starlight blooms!] 】

[The bottom of the entire abyss is as bright as day, and you can clearly see the true face of the 'Black Thorn Demon'......]

[It resembles a giant snake magnified thousands of times, with long black spines on its back, four huge black wings covering most of the body of the winding snake, and two huge heads connected to the body of the snake. 】

[One head has a strange face similar to a human face, and the warm light like a lantern hangs from the top of the head, and the other head has a fierce and hideous snake head.] 】

[In the starlight bloom, the 'Blackthorn Demon' seems to have been slightly injured, and its strange face is full of pain. 】

[And the other snake head, opening its big mouth and revealing its fangs, is rapidly attacking you......]

Lin Xun gave instructions to the Valkyrie according to the tactics he had planned in advance.

As long as Valkyrie steps forward to contain the boss, he can hide in the rear and output steadily.

['Battle Angel - Valkyrie' fluttered her wings and flew into the air, and she shot arrows in an attempt to attract the attention of the 'Black Thorn Demon'. 】

[Blood flowers bloomed on the 'Black Thorn Demon', and the huge snake head did not pause at all, and rushed straight towards you!] 】

“…… This boss doesn't play according to the routine! ”

He never expected that the usual tried and tested tactics would fail.

The 'Blackthorn Demon' completely ignored the Valkyrie's attack and tried to kill him hiding in the rear.

Lin Xun took a deep breath and did not panic at all.

Because he is 'cautious by nature', he also prepared a set of Plan B.

[You raise your hand and the 'Pre-Stored Spell Ring' shines brightly......]

[The 'Knowledge Grating' rises from the ground and protects you firmly!] 】

[In the bloody wind blowing in your face, you calmly open a pink eye......]

[Special Skill 'Joy Smoke' is activated!] 】

[The huge snake's head stiffens suddenly......]

[You take the opportunity to quickly retreat to a safe distance, and wave your hand to raise a 'knowledge grating' to protect yourself.] 】

You're feeling a little tired! 】

Lin Xun smiled slightly.

The strength of the demon boss is indeed strong, and even the legendary skill Meteor Light can only cause 'some injuries' to it.

However, the body of the master can be controlled and output at the same time, although it is very mentally consuming, but it is enough to beat the boss into a half-crippled state.

As expected, when the fatigue value was about to run out, he replaced the overworked growth shell and switched the earth giant to make up for it.

The tactics were perfect!

[The giant serpent's head still froze in the distance, you raise your staff and recite the incantation again......]

【……】

[You are chanting a spell, suddenly notice that something is wrong, the snake head that seems to be frozen in the distance is motionless, but the snake letter in its mouth is still swallowing. 】

[You seem to see a hint of a playful gaze coming from the vertical pupils of the snake's head......]

[A huge strange face peeks out from the darkness behind you, and it bites the 'knowledge grating' and swallows you into its belly!] 】

[A dark ...... in front of your eyes]

【……】

[You're dead!] 】

？？？

"Wang Defa? I'm just going back to the city for free? ”

Lin Xun's eyes widened, a little incredulous.

[Ordinary geist reborn in the Multivision Association......]

The bad news is that he died, and the good news is that Valkyrie did not die.

He reviews the texts before his death for clues.

The 'Black Thorn Demon''s defense doesn't seem to be very strong, and the Valkyrie's attack can easily break through the defense.

The Legendary skill 'Falling Starlight' hits the enemy and deals a lot of damage.

According to the usual rhythm, even if the containment plan fails, he can use the alternate plan to control and output at the same time, and deal a huge amount of damage.

'Joy Smoke' did control the boss, but the control time was not satisfactory, and it could not support him to release the light of the meteor.

On top of that, one boss is controlled, while the other is able to move freely.

This was far more than he expected.

"How do I kill the Blackthorn Demon?"

Lin Xun fell into deep thought.

He opens his inventory to find items.

After looking through it for a long time, I couldn't find the relevant props that can restrain the boss.

"Could it be that the 'Calling Eye of the Overlord' is needed here?"

A powerful prop that can be used as a hole card, Lin Xun is reluctant to use it like this.

If there is another way to overthrow the boss, he will definitely save the hole card items.

Suddenly, an eyeball in the inventory that had not yet been transplanted came into view.

['Eyeballs of the Shadow Demon King' (Epic)...... This item needs to be used with the vacant eye socket, and after use, there will be a certain chance to obtain, and the special effect 'Dark Shadow'. 】

His eyes lit up, and he hurriedly went straight to the 'Eyeball Laboratory' on the second floor of the building.

[You step into the 'Eyeball Laboratory'......]

[Bennet, wearing a beak mask, is in front of the experimental table, operating the experimental equipment, it seems that he has learned the knowledge of 'eye fusion', and tries the relevant experimental techniques normally. 】

[When it saw you coming, it quickly put down the work in its hand and asked if you needed an eye transplant? 】

[You nod and pull out the 'Shadow Demon King's Eyeball' and hand it to it......]

【……】

The transplant did not go well.

The 'Eyeballs of the King of Shadow Demons' that Lin Xun obtained were two.

He wanted to know the specific effect of the name 'Dark Shadow' first, so he only transplanted one eye into the Faye's body.

As a result, the Arch's body did not gain the special effect of 'Dark Shadows'.

He did not believe in evil and repeatedly had eye transplants removed, but the results were the same.

At Bennett's reminder, he learns that there are two possibilities for this to happen.

One is that the strange power contained in the eyeball is too small to support the body to comprehend the special effects, and perhaps another identical eyeball can be obtained to the operation.

The second is that the strange power contained in the eyeball does not match the body, resulting in the body being unable to assimilate the power in the eyeball.

Lin Xun could only try to change the body and transplant it continuously, which made Bennett tired enough.

When a pair of eyes are transplanted to the dancer's body, he finally understands the 'dark shadows'.

['Shadow of Darkness' (special effect), Shadow Demons of the Underworld can move quickly in the darkness, making it impossible to catch their shadows.] The eyes, which are the essence of concentrated shadow demon power, certainly have the same effect. 】

[Obtaining this effect will strengthen your stealth skills, making it difficult to see]

[This enhancement effect is linked to the brightness of the current environment, and your invisibility effect will be greatly enhanced in a dim environment.] 】

Lin Xun had mixed blessings.

Happily, the most practical stealth skill has finally been strengthened, and the dancer has been given a chance to appear again.

The worry is that 'Dark Shadows' does not help much in attacking the underground demon boss.

Unless the dancer can kill the boss in one hit, it will still appear after the attack, wasting a little soul strength in vain.

"If the master has stealth skills that can adapt to the enhancement effect of the eyeballs, then the demon boss is not ready to be captured."

After the master released the skill, he ran away incognito, lurked to a safe distance, and then cast a spell and chanted a spell...... This cycle is equivalent to joining the 'Wind Spirit Moon Shadow Sect', which is no different from opening the hanging.

However, the enhancement effect of the eyeballs is linked to the brightness of the environment, and if it is in a brightly lit area, the enhancement effect will be greatly reduced.

Lin Xun pondered for a long time, but he still didn't think of a way to attack the demon boss.

He thought about it for a long time and decided to use the most primitive method - Lida Flying Bricks.

If you can't kill the boss, it means that he is not strong enough, and in the face of absolute strength, there is no need for restraint skills, restraint props and the like.

"Maybe the demon boss is a boss that has to be pushed hard, and there is no way to skip class."

At this time, there was still more than half an hour left before the soul strength returned to two points.

If you want to reshape the body of the master, you have to wait until half an hour later to fight the boss.

Counting the spirituality in his pocket, he has saved 590,000 yuan, which is quite a huge amount of money.

Among them, the contribution of the 'Obstacle Trolls' is indispensable, which greatly increases the thickness of his wallet.

There are so many spiritualities that just happen to hit the stuck level, and it is too much to say if you don't strengthen your strength.

Lin Xun took advantage of the fact that his soul strength had not yet recovered and teleported back to the library.

【……】

[You step forward and touch the 'Book of Trading', and ordinary spirits resonate with the book......]

In the strategy chapter, the Netherworld game will automatically block the available items related to the content of the chapter.

It's not realistic to rely on buying and selling strategy items in the Book of Trades.

However, where there are rules, there are loopholes, and the Apostolic Council is very intimate to launch relevant services for the registered apostles.

The item trading section of the Apostle Forum has a channel for purchasing designated items.

The official has made a lot of money by relying on the trading channels, and it is very rich......

Lin Xun rummaged through the book of transactions.

Since he has not yet completed the fourth difficulty, the items displayed in the book are all items that do not exceed this difficulty.

There are very few epic equipment in the book of trade, and he only saw three pieces of epic + level equipment when he rummaged through all the top equipment.

Compared to the value of the more than 100,000 spirits of epic-level weapons, there are only two Epic+-level armor in the Book of Transactions, one for 380,000 and one for 450,000.

And the Epic + weapon called 'Sword of Victory and Oath (Replica)' has a price of a series of 9s, which is only 1 point away from the million-dollar price......

"I'm really ...... You sell it so expensive, who can afford the four difficulty apostles? ”

Lin Xun scolded and scolded, looking for arrows for the Valkyrie.

Most of the equipment on his body is epic, and changing two epic+level weapons and armor will not bring a qualitative improvement.

It's better to use spirituality to buy a few powerful arrows for the Valkyrie, which will bring a big boost.

Lin Xun has a lot of money in his pocket, and he finds arrows and sorts them directly in descending order of selling price, and only buys the most expensive and awesome arrows.

Looking at the arrows that were ranked first, he directly closed the sales channel.

"Who do you look down on...... Twenty-nine thousand arrows can match the Valkyrie? ”

He clicked on the auction channel and continued to look for arrows.

There are not many arrows sold in the auction channel, and the prices are high and low.

Suddenly, an arrow locked his gaze.

[Arrow of the Crusade against the Dragon (Epic Arrow), a bloodstained thick arrow, the arrow is not sharp but very rough and blunt. This seemingly ordinary arrow has killed several evil dragons, and its deep layers are infested with dragon blood. 】

[Using this arrow, after being shot, the evil dragon soul will be blessed, so that the power of the arrow will be greatly increased.] 】

[This arrow is only suitable for heavy bows such as longbows and giant bows.] 】

[The starting price of the item: 50,000, and the price increase is not less than 5,000 spirituality each time.] 】

[Current price of the item: 71000, remaining auction time 0:21:36]

Lin Xun clicked on the arrow and faced the pop-up option of whether to participate in the price increase.

He didn't hesitate to click on the price increase, and increased the price to 80,000 spirits.

The price of high-grade arrows is not low, although it is not as good as the bow itself, but it can reach up to half or even more than half the price of the same level.

The epic bow in the library costs about 100,000 and less than 200,000.

The selling price of this powerful arrow is not too high.

Lin Xun waited patiently after bidding.

He wasn't worried that someone would raise the price at the last second to buy the arrow.

Just because after he made his bid, the text showed that the remaining auction time had changed from twenty-one minutes to an hour.

After a long wait, when there were only ten minutes left in the auction time, someone raised the price to 85,000.

Lin Xun was too lazy to grind, so he directly increased the price to 100,000 spirituality.

He's still in a hurry to go back to the chapter to push the boss.

I waited a long time again, and until the countdown was over, no one made any more bids.

The price of 100,000 spirits seems to have scared off a bunch of buyers who were waiting to buy.

Lin Xun successfully harvested a powerful arrow.

Satisfied, return to the Hell chapter and insert the 'Arrow of the Crusade against the Dragon' into the Valkyrie's quiver.

Everything is ready, and he decides to change his position and push the boss!

【……】

['Battle Angel - Valkyrie' takes you slowly down to the ground.] 】

[The bottom of the abyss is full of foul-smelling silt, and the black lacquer mud floods your ankles and reaches the middle of your calves.] 】

[You vaguely see a faint warm light in the boundless darkness in the distance.] 】

[Resurrection from the dead, you know in your heart that it is the 'Ancient Abyss Demon, the Black Thorn Demon' to lure food. 】

What should you do? 】

Once again, the game text pops up with three options.

Lin Xun ignored the options given by the underworld game and attacked directly!

[You raise two staffs and recite the incantation silently......]

【……】

['Battle Angel - Valkyrie' draws a thick arrow from her back and places it on top of the longbow......]

[She looked at the little warm light in the darkness, hummed a moving melody, and slowly closed her eyes. 】

[Countless tiny characters flowed around the 'Arrow of the Evil Dragon', and then a white light flashed......]

[The dragon roars through the abyss!] 】

[The arrow turned into a pure white dragon and shot towards the 'Black Thorn Demon'! 】

You pronounce the last syllable of the incantation. 】

[Bright starlight illuminates the boundless darkness!] 】

[Starlight and the pure white dragon hit that hideous monster face together, and under the powerful attack, the head instantly turned into ashes!] 】

['Blackthorn Demon' has been injured a lot!] 】

[The hideous snake head attacked you, and in the bloody wind, you calmly opened a pink eye. 】

[Special Skill 'Joy Smoke' is activated!] 】

[The huge snake's head freezes suddenly......]

Now is the time!

Lin Xun narrowed his eyes and quickly switched his body.

[You are possessed by the body of the 'Sunken Earth Giant'! 】

[Your size has risen suddenly, and in the blink of an eye, you will become a giant who stands tall in the sky! 】

[You open a red eye.] 】

[Special Skill 'Burning Eyes' is activated!] 】

[The 'Ancient Dragon's Tooth Giant Stick' in his hand ignited a raging fire, and the flame of the 'Unquenchable Flame' illuminated the darkness. 】

[You let out an earth-shattering roar, brandished the murder weapon in your hand, and smashed it at the 'Black Thorn Demon'. 】

[The terrifying wind pressure enveloped the monstrous flames and smashed into the behemoth serpentine monster.] 】

['Battle Angel - Valkyrie' took advantage of the light of the fire, pulled the longbow, and launched an attack on the demon's other snake head......]

[The 'Black Thorn Demon' was wounded again, and the wriggling snake body wrapped you in a group, and your giant-like body was like a young child in front of the ancient abyss demon. 】

[During the entanglement and squeezing, your bones make an overwhelming clicking sound, and you scream angrily and exert all your strength, but you can't break free from the shackles of the demon.] 】

[The Valkyrie frequently shoots arrows at the 'Black Thorn Demon', but she can't attract its attention, and the snake demon still entangles you to death.] 】

[You gradually feel severe bone pain all over your body, difficulty breathing......]

You realize that death is coming! 】

[The 'Black Thorn Demon' raised its head high, opened its huge mouth full of fangs, and came from above to devour you......]

[When you raise the head of the snake, you suddenly notice that there is a huge blood-red spot on its abdomen. 】

[You open a big pale eye......]

[Special Skill 'Weakness Insight' Activated!] 】

[Your knowledge is not as good as the enemy, and the judgment is ......]

[Due to the blessing effect of the same kind of eyeballs, the judgment is successful! 】

[You have detected the Achilles heel of the 'Blackthorn Demon'! 】

[Your next attack will have a high chance of hitting its weak point!] 】

['Battle Angel - Valkyrie' quickly pulls the bowstring and shoots at the blood-red spots on the demon's belly.] 】

[The serpentine demon spreads its four black giant wings and wraps itself around its Achilles' heel. 】

[The 'Black Thorn Demon' flicked its giant tail and whipped the Valkyrie in mid-air, but it still didn't let go of its entanglement around you.] 】

[You have severe pain all over your body, difficulty breathing, and your limbs gradually weaken......]

[The snake demon swallows you into the belly......]

【……】

[You're dead!] 】

Lin Xun put down his phone and breathed a long sigh of relief.

Because of his shallow knowledge, after several times when his knowledge was not as good as the enemy's judgment, his 'Weak Insight' was almost forgotten by him.

Unexpectedly, after transplanting the eyeballs of the 'Ancient King Crimson Dragon', even if the amount of knowledge is not as good as that of the enemy, there is still a probability that the judgment will be successful.

"It's the first time I've fallen twice in the same monster's hands...... It's a record-break. ”

Lin Xun sighed, but he was not discouraged in the slightest.

Because he's found a way to take down the 'Blackthorn Demon'!
