Chapter 133 The Last Hope, the Purple Light Curtain Opens!

Although King Kong didn't know what Lin Yuan's final solution was, he always had unconditional trust in Lin Yuan.

Soon, Lin Yuan brought King Kong to the entrance of the underground world.

At this moment, Lin Yuan's ears suddenly heard a shrill scream!

Lin Yuan instantly determined the source of the wailing sound...it was the undead beast summoned by Frius!

He obviously didn't expect that the giant undead beast would be killed so easily after he had only been away for about a quarter of an hour!

Fortunately, he took advantage of the stalemate between those strong men and chose to escape back to Skull Island without hesitation.

Otherwise, it was probably him who died there!

"walk into!"

Lin Yuan didn't waste any time and immediately entered the underground world.

Then, he took King Kong and headed towards the Black Palace at the fastest speed.

The last way to protect Skull Island is here!

It is not easy to keep up with Lin Yuan's speed.

After arriving at the Black Palace, King Kong was so tired that he was breathing heavily.

Lin Yuan took a deep breath and stepped into it.

After entering the deepest hall, he immediately stretched out his giant claws and held the purple crystal that had been placed in the center of the hall in his hand.

This purple crystal is the key to his success in defending Skull Island!

After obtaining the purple crystal, Lin Yuan immediately said silently in his heart: "System, I choose to redeem the planet-level energy shield!"

"Ding, congratulations to the host for successfully redeeming the planet-level energy shield. 10,000,000 evolution points will be deducted."

Lin Yuan didn't hesitate at all, and directly spent 10 million evolution points to redeem an item from the system mall!

The next second, a special device with a full sense of technology appeared in front of Lin Yuan.

This is the planetary energy shield.

However, to drive this device, an energy core is needed.

Moreover, the greater the energy contained in the energy core, the more powerful the protective shield formed.

And Lin Yuan wanted to use this purple crystal in the black palace to provide energy for the protective shield in front of him!

If he had no choice, Lin Yuan would definitely not do this.

Because, once the purple crystal is used as the energy core of the energy shield, the entire underground world will be equivalent to completely losing its energy source.

In other words, the energy in the underground world will be quickly depleted.

Under this situation, giant beasts such as King Kong, Shura Demon Wolf, and Holy Tiger King, and even Lin Yuan, will evolve extremely slowly due to lack of energy.

Although doing so can indeed protect Skull Island from invasion by powerful humans in the short term, for the giant beasts on Skull Island, it is nothing more than a slow death.

This is also the reason why Lin Yuan has never chosen to activate this plan.

But now, no matter how unwilling he is, he has to choose to use this method.

Because, with his current strength, it is simply impossible to compete with the strongest among humans.

In fact, he has another option, which is to abandon Skull Island and dive directly into the deep sea.

For Lin Yuan, perhaps this is the best choice.

After all, the target of this group of strong human beings is not him at all, but just the secret realm on Skull Island.

If Lin Yuan abandoned the island and fled without posing a threat to human society, it would be almost impossible for a strong human being to deliberately pursue him.

Just like this time, even if Lin Yuan escaped back to Skull Island under their noses, the strong humans did not react at all.

However, although this is the best way, it does not mean that Lin Yuan will choose to do this.

Because...he can't do it.

These giant beasts on Skull Island may not have too complicated emotions, but to Lin Yuan, they are all companions.

King Kong, Shura Demonic Wolf, Holy Tiger King, Winged King, Long-legged Spider Monster...

If Lin Yuan was to let these giant beasts die in front of him, he would never be able to do it.

Therefore, even if it may be chronic death, Lin Yuan must seize this last glimmer of hope!

Doing something you know you can't do is, at the very least, better than having no hope at all!

Lin Yuan just wants to live this life again without any burden!

Therefore, without any hesitation, Lin Yuan directly put the purple crystal in his hand into the device in front of him!

"Click!"

The groove of the protective cover device automatically recognized the shape of the purple crystal and fit it in perfectly!

The next second, an invisible energy pulse, with the protective shield device as the core, swept towards the surroundings!

Such significant energy fluctuations, not to mention Lin Yuan and King Kong who were closest to the protective shield device, even all the giant beasts on Skull Island felt it and raised their heads in surprise.

In their sight, a semicircular purple energy shield appeared above Skull Island, like a giant upside-down bowl, covering the entire Skull Island!

No one of the giant beasts knew why the purple light curtain in front of them appeared out of thin air.

After doing all this, Lin Yuan couldn't help but breathed a sigh of relief.

In this way, at least in a short period of time, he would not have to worry about Skull Island being destroyed by strong humans.

Lin Yuan once asked the system how many attacks the planet-level protective energy shield could withstand.

The answer given by the system is that it depends on the energy core placed in the device.

If the purple crystal in the black palace is used as the core, it can withstand hundreds of full-force attacks from planet-level experts!

It is precisely because of this that the price of this planetary protective shield is so expensive!

Moreover, this was even under the condition that Lin Yuan did not choose to purchase the energy core.

To activate this device, the quality of the energy core is extremely high. Even the cheapest one requires 30 million evolution points.

As for higher quality, it will just be more expensive!

This shows how precious the purple crystal in the black palace is.

According to the concept of the system, only those with enough strength to destroy an ordinary planet can be called a planet-level powerhouse!

In other words, the protective shield currently covering the entire Skull Island can withstand at least hundreds of attacks that are enough to destroy the earth!

If hundreds of SSS-level experts join forces to attack, it will take at least a full year to break through this protective shield!

Lin Yuan didn't know if there were any planet-level experts on Earth.

However, even if there were, the other party would never take action because of a mere secret realm.

Therefore, in Lin Yuan's opinion, no matter what, this purple protective shield can last for several months at least.

And all he has to do is to come up with a complete solution to this predicament in the past few months!
