What is the opening of the spirit cage wasteland for a leisure system?

"Although I feel like it might be a bit stupid to ask, do you have any extra water to make another cup of coffee?"

Bai Yuekui looked at Ye Xiwen eagerly, with anticipation in his eyes!
At this moment, Ye Xiwen was drinking coffee happily, holding the cup with both hands, and shrugged slightly!

"I think it's only enough for me, but you can boil some more water!"

"Okay! I really shouldn't have asked this question!"

Bai Yuekui supported his forehead, then stretched out his jade hand to pick up the cup!Silently drinking the tasteless tea!
Boom boom boom!

There was a sound from the earth, and a dull sound came out!
The expressions of Bai Yuekui and Ye Xiwen tensed instantly!
Raise your eyes and sweep away into the distance!

At this moment, the war is about to break out!
The base that was shielded by spirit stones finally revealed its appearance under the intrusion of many polar devouring beasts!

As the Lingshi Formation was broken through, the outside world was like a layer of camouflage tulle faded away, and the sensation of the Pole Devouring Beast was instantly strong,

They rushed towards the interior of the base one after another!

And inside the base,
At this moment, a large number of people are guarding the site, almost all of them are junior genetic fighters!

The combat power is very high, and almost all exist with one against a hundred!All hands are Leiyin overclocking knives,

Just formed a circle around the periphery, waving the overclocking knife in the hand,

The offensive methods of those polar devouring beasts are very rough, they just rely on numbers to crush them, without any strategy at all!

Looking back at the base, the genetic fighters had a neat line of defense, and their advances and retreats were well-founded, but the number was extremely unequal to that of the polar-devouring beasts, and the two were at a stalemate here for a while!

In the center of the base, Ye Xiwen's old acquaintance, Jackney, is in charge of commanding!
His body has already been transformed into a Tier [-] genetic warrior, and his abilities have made great breakthroughs in all aspects!

The energy and blood on his body was much stronger than that of a Tier [-] fighter, Ye Xiwen felt an urge to go forward and devour it!
Beside Jackney, there is still the Tiandi Xuanhuang gang of four!

It's just that at this time, their strength has once again increased a bit, reaching the peak state of the second order,
It is almost comparable to the third-order genetic warrior!
Ye Xiwen was speechless for a while when he saw the people in front of him.

"How many genetic fighters are there in this Nirvana base! Why can't they always kill them all!"

Bai Yuekui kept his eyes on the battlefield, but at the same time answered Ye Xiwen's question!

"Nirvana's experimental specimens will almost back up dozens or hundreds of clones at the same time. The purpose is to continuously optimize the genes and select high-quality gene chains from them!!"

"Oh, I see!!"

Ye Xiwen nodded when he heard the words, and had a general understanding of this in his heart.

This gene optimization program also has to follow the rules of step-by-step, it doesn't happen overnight!
It takes a lot of time and resources to cultivate from the primary to the second level, and even more from the second to the third level.
This is also the fundamental reason why there is only Jackney, a Tier [-] genetic warrior, in the Nirvana base!

Now that we are in the last days, even if the Nirvana base has sufficient resources, they are still limited. It is also extremely limited to create enough genetic fighters in a short period of time.

And a large number of reserve clones ensure the output of the number of genetic warriors!

now,

The duck-clawed beast waved its arm,
More than a dozen large polar devouring beasts began to march towards the base along the herd.

In the base, Jackney also waved,
Seven or eight second-level genetic fighters were also ready to go in no time, carrying the Leiyin overfrequency knife, jumped in front of the junior fighters and slashed with their knives!

This scene seemed familiar, making Ye Xiwen seem to have returned to the past, the glorious years of playing tower defense games!
The scene in front of me is like a live-action tower defense game!

moment,

The large pole devouring beast that came with the beast tide has already pushed to the front of the base formation,
Opening his bloody mouth, he bit the second-order genetic warrior in front of him,
Those second-order genetic fighters are very flexible, swinging their bodies, wandering around the pole devouring beast,

Two second-tier fighters stabbed the overclocking knife into the mouth of the beast, and then used the knife to cut both sides of the beast's mouth,

At the same time as the wound was opened, a Tier [-] fighter quickly got into the mouth of the Pole Devourer,
The knife in his hand was in the mouth of the Pole Devouring Beast, extending all the way to the belly, with a burst of slashing,
The pain caused the Pole Devourer to howl,

Until a certain moment, a certain knife of the second-tier warrior chopped up the beast's consonance seed, and then the flesh and blood of the beast turned into a pool of black blood!
And those remaining polar devouring beasts are also unwilling to be lonely,
I saw one of them, grabbed a second-tier fighter, and slammed it on the ground several times, weakening the resistance of the second-tier fighter.

Then put it in the mouth, and there was a click, click, click,
From the corner of the big mouth, a burst of viscous red liquid spewed out from time to time,

Crunchy, chicken flavored!
For a time, both sides hurt each other!

Seeing this, the duck-clawed beast waved its arm again,
The several metamorphic and devouring beasts beside them also started to move!
Then Jackney saw a change in the metamorphic polar devouring beast,
With the same wave of the arm,
Seeing Tiandi Xuanhuang's four-person gang was dispatched, they all clenched their weapons tightly and rushed towards the front line of the battlefield.

Seeing this scene, Ye Xiwen felt a little suffocated, almost spat out a mouthful of old blood!

Bai Yuekui's complexion also changed slightly,
Come on, isn't this a tower defense game?Does the Pole Devourer only know how to attack?

What about your strategy when you attacked the Mutian base?
How good was it to play throwing with one hand at that time, and how about the transformed laser to clear the way?

Why is it only attacking and pushing towers here?

"Boss, are these extreme devouring beasts out of their minds?"

"It doesn't look like it! They are all acting according to instinct!"

Bai Yuekui frowned slightly, then seemed to have figured something out, and then turned his gaze to Ye Xiwen!

At this time, Ye Xiwen also set his sights on Bai Yuekui!

The two looked at each other and came to a speechless conclusion!

"It's not that the Pole Devourer's brain is out of whack! It's the Chan Tao who commanded the fight against the Mutian base. His IQ is too high!"

Ye Xiwen looked at Jackney and the duck-clawed beast who were pointing to the country, and his heart was filled with turmoil.

"It's a good offensive and defensive battle, and it has turned into a tower defense game. The IQ of these two! It's worrying!"

On the battlefield,
The metamorphic and devouring beast still advances to the base along the tide of beasts, and it will not hurt its own pan-formed polar-devouring beast at all!
Seeing Ye Xiwen was speechless for a while,
Please, please, hurry up!

Don't stretch the battle line too long, you bastard!

If you don't do it again, I can't help but do it!

Tianyou, Diqing, Xuandaoliu, and Huang Yingming had no intention of doing anything at all.

Instead, standing in front of the junior fighters like the former second-tier fighters, they looked at the metamorphosis and devouring beasts that were advancing, with a look of contempt on their faces!

This made Ye Xiwen feel a tightness in his lower abdomen, and he had an urge to hit someone, which seemed to be unstoppable!
What a sarcasm, what a sarcasm!You stepped forward to deal with them, hey! !
