After advancing to the 6th order, Chu Xun's strength has been qualitatively improved. Not only has his strength, defense, and resilience become more terrifying, but his speed has also increased dramatically, fueled by the already gigantic flesh wings.

Rumble!

But this is not a game after all, and the huge improvement in all aspects also makes Chu Xun unable to perfectly control his body for a while. At this moment, I saw that he had just waved his wings with all his might, and the whole person rushed out of the energy enveloping range of the crystal pillar, and then slammed into the outer wall of the energy base, smashing the outer wall of the base that was several meters thick and covered with a layer of alloy metal.

With such speed and such power, Chu Xun has completely turned into a destruction machine for violent demolition!

"Damn, the improvement is too big, I can't adapt to it at all!" Standing up from the fragments of the collapsed outer wall, Chu Xun's face suddenly became extremely ugly.

Like the underground bases built by humans, the underground bases of Bone City are also in a classic beehive design. Although this design maximizes the use of underground space and ensures the stability of the underground base, it also makes the underground base twisted and full of corner passages.

And with Chu Xun's current speed, once he launched a charge, it would be almost difficult for him to control his ability to pass freely in this intricate underground base. But if he slowed down, it would be an impossible task to break out of the underground base and break through the Scarlet City's energy shield in just 30 seconds!

"The host, after calculation, with the current strength and speed of the speed, can completely break through the main body of the building of the underground base, and directly make a way out of the underground base in a straight line, which is faster than leaving the underground base according to the original path!"

At this moment, the system prompt sounded again rapidly.

"yes,, I'm in a hurry!" Hearing the prompt of the system, Chu Xun suddenly realized, let him take a deep breath, squatted slightly with his legs, and at the same time the wings behind his back began to accumulate.

"Warning: Base nukes will detonate in 25 seconds!"

"Warning: The energy system will self-destruct in 25 seconds!"

Rumble!

Almost at the same time as the piercing siren sounded again, a violent roar also resounded throughout the underground space, and at the same time, the entire underground base began to tremble slightly, as if it had been stepped on by some giant.

At the same time, the ground under Chu Xun's body also exploded, as if a nuclear bomb had been detonated in advance, and a huge pit was blasted out by that indescribable terrifying force, and at the same time, countless pieces of rubble were also shot out like shrapnel from cannonballs, bombarding everything around them into potholes and shattered.

With the help of the terrifying power coming from the ground, as well as the help brought by the sudden waving of the wings behind his back, Chu Xun's whole person disappeared in place almost at the moment when the ground shattered, and turned into a black streamer, and finally like a broken bamboo, he began to continuously break through layer after layer of underground base compartments in bursts of violent and dense roars, and finally successfully penetrated the entire underground base, as well as the tough rock layer hundreds of meters above the base, and rushed out of the surface!

"Warning: Base nuclear weapons will detonate in 10 seconds!"

"Warning: The energy system will self-destruct in 10 seconds!"

And it wasn't until he burst out of the surface that the shrill sirens sounded again.

In just 15 seconds, Chu Xun broke through the underground base and rock formations that were nearly a thousand meters thick, and rushed out of the surface, such terrifying strength and speed were simply terrifying!

But even so, Chu Xun's time is becoming more and more insufficient! Therefore, after rushing out of the surface, Chu Xun almost did not hesitate, he waved his wings behind his back again, soared into the sky, and rushed towards the azure energy shield in the sky, which had obviously become a little faint!

With only 10 seconds left for the Underground Base's nuclear weapons and energy systems to detonate at the same time, he must defeat the Energy Shield in those 10 seconds, and get as far away from here as possible!

"Break it for me!"

In just the blink of an eye, Chu Xun disappeared from the ground, and then appeared in front of the azure energy shield, and swung his right fist, smashing it the energy shield.

Rumble!

The terrifying power unreservedly slammed into the azure energy shield along Chu Xun's right fist, and made a loud roar. Subsequently, the energy shield that enveloped the entire Blood Bone City also began to tremble violently as if it had been punched hard by some giant, and countless ripples of energy like water ripples appeared, and a large number of electric sparks also burst out, obviously suffering huge damage!

But after all, this is the energy shield of a million-level city, and the strength of the defense is even a hundred or even a thousand times that of the energy shield of Chu City and Wolf Tooth City. So even if the energy of the shield had been greatly weakened at this moment, it was not something that Chu Xun could easily break with one punch.

And more importantly, Chu Xun is still facing the same problem at this moment as in the 5th Order period, that is, his strength is too strong and his body is "too weak". At this moment, under Chu Xun's unreserved bombardment, although the energy shield was seriously damaged, the ensuing shock force caused Chu Xun's right fist to collapse violently, the exoskeleton armor exploded almost instantly, and the arm muscles under the armor were completely torn, shooting out light red acid blood.

Even if it weren't for the energy conversion system that helped him absorb most of the shock force, I'm afraid that his current injuries would have become more serious!

"Malegobi's, break it for Lao Tzu!" However, Chu Xun couldn't care about the injury on his right arm at this moment, and while the ripples of the energy shield had not faded away, Chu Xun also used the power fed back from the energy conversion system and the huge momentum brought by waving his wings, roared angrily, and swung his left fist with all his might, smashing towards the turbulent energy shield!

Now the alarm that originally sounded once every 5 seconds has become 1 second 1, so Chu Xun can also clearly know that his time is only the last 8 seconds!

And at this moment, his right arm has been severely traumatized, so if the punch of this left arm can't break through this energy shield, this is afraid that it will be the last punch of his life!

Rumble!

However, fortunately, at this moment, under Chu Xun's full outburst, his strength was no longer lost to a 7th-order strong system ability, and he even had a victory. And in the face of the continuous attacks of such a terrifying force, the energy shield, which had been greatly weakened, finally couldn't support it, and began to completely distort and turbulent in a violent roar, and finally completely collapsed and exploded!

Burst!

The violent shock wave caused by the explosion of the energy shield, as well as the shock from the punch just now, made Chu Xun's left fist also follow in the footsteps of his right fist, which was seriously damaged and almost scrapped. At the same time, his internal organs were also damaged by the shock wave and the anti-shock force, so that he couldn't help but spurt out a mouthful of blood, and the man was even swept backwards, slamming into a building, completely smashing it to pieces.

And at this moment, the piercing countdown has been counted down to 5 seconds!

"Grass!" Hearing that the countdown was getting less and less, Chu Xun's face changed again in the ruins of the building, and then he waved his wings violently, directly sweeping away the wreckage of the surrounding buildings, blowing them away, and then the whole person kicked the ground violently, spread his wings, and turned into a black streamer at a very fast speed, rushing towards the sky.

Under the reckless full acceleration, Chu Xun's speed has reached at least 3 times the speed of sound, and the speed per second has even exceeded 1000 meters!

But even with such an astonishing speed, it is still a fool's dream to get out of the enveloping range of a nuclear weapon explosion in just 5 seconds, and it is completely impossible!

Countdown to 5 seconds, 1000 meters!

Countdown to 4 seconds, 2000 meters!

Countdown to 3 seconds, 3000 meters!

Countdown to 2 seconds, 4000 meters!

Countdown to 1 second, 5000 meters!

Under Chu Xun's full flight, it only took 5 seconds for him to fly high in the air, and at the same time, the air friction caused by the violent acceleration also made his body exude a steaming heat, which was completely different from the high altitude where the cold wind was howling!

And almost at the same time that Chu Xun rushed up to an altitude of 5,000 meters, a huge "sun" suddenly appeared in the Blood Bone City, which had almost become a small point under him, and this "sun" was still getting bigger and bigger, bigger and bigger!

"Damn it!" Looking at the incandescent "sun" below, which was gradually getting bigger, Chu Xun's face changed drastically, and then he subconsciously wrapped himself around the fleshy wings behind him, ready to withstand the impact of a nuclear explosion!

Life and death, in this moment!
