.

Everyone behind Xuan held their breath and greeted them together.

The paint had peeled off quite a bit, and the rusty "two cars" were constantly shaking and making a "creaking, creaking" sound as the brakes followed.

Because the carriages were all pitch black, even Lu Xuan had no way to determine whether there were people in these two carriages now.

"Don't bring the demon back, never bring the demon back. ”

The white glasses man behind Lu Xuan couldn't stop muttering, and the other five white engineering suits, although they didn't speak, were obviously more nervous, and their hands holding guns were shaking unconsciously.

Xie Juan next to Gauss, who is usually calm, also looks like a great enemy at this moment.

Cheng Haofeng, the strongest individual soldier from the Black Pages, has become synonymous with "demon" at this time.

"Ding"

After a crisp bell, the two carriages, with a total of four doors in front and behind, opened together.

No one got out of the car, everyone looked at the dark carriage, but they didn't dare to relax in the slightest, who knows what is hidden in the dark?

Lu Xuan carried Qiao Qiao on his back and stepped into the first carriage without hesitation, and the sensor lights in the carriage lit up one after another, illuminating the carriage with snow white.

Inside the carriage, the black seats and aisles on both sides look old, but they are still clean.

"Cheng Haofeng didn't come back with the train, let's come in, the car will start in three minutes, and go to the alien mother queen's lair at the bottom of the black iron mine. ”

Lu Xuan said in a calm voice while picking the most comfortable position for Qiao Qiao and gently placing her on it.

The white engineering uniforms rushed in, and only Xie Juan stood in place without moving.

"Aren't you going to get in the car?" Lu Xuan was a little surprised.

"Lu, I'm worried about a problem right now, and if this problem is not solved, I may not be able to get into this car. Xie Juan smiled charmingly.

"Hmm. ”

"What if our car is halfway through and someone uses a program to forcibly call our car back through the console?"

As soon as Xie Juan's question came out, the faces of the white engineering uniforms in the car suddenly changed.

"Miss Xie's question is critical. If we are called back halfway, we are in trouble. The man with white glasses frowned.

"Well, that's not a problem, the program of the console has been changed by me, and all the instructions will no longer have any effect. Lu Xuan said coldly.

"It's worthy of Lu. Xie Juan walked up with a relieved expression.

"Doot toot!"

The buzzer of the electronic door kept making a rapid sound, signaling that the door was about to close immediately.

"Brush"

The four doors closed together, and all the sensor lights in the carriage went out at the same time, and everyone immediately fell into darkness.

"Lu, what's going on?" the white glasses man's voice was a little panicked.

"To save energy. The sensor light will automatically turn off after the train starts, and there is an emergency light switch in the car, so I recommend not using it easily, the journey is estimated to take more than four hours, so you can take this opportunity to recharge your batteries in the dark. Lu Xuan explained lightly.

The carriage trembled slightly as it started. The crowd in the darkness also shook slowly.

The train started gradually, and the speed increased little by little. The starting point of the crowd grew smaller and smaller in everyone's field of vision, and soon disappeared into the darkness.

The faster the car. Comparatively speaking, the smoother the ride.

So, when I first entered the carriage, I kept ringing in my ears with "clang." The "clang" sound disappeared and was replaced by the whistling sound of driving.

In the endless dark tunnel, an old subway train sped towards the unknown.

In the dark, Lu Xuan closed his eyes, but he was not ready to rest. It's about seizing the time and breaking through yourself.

Because the next opponent, whether it is Cheng Haofeng or the terrifying alien queen, is not something that he can easily shake now.

Previously, in the security base, the three combat aliens that were killed by him using the ancient martial arts ground hammering method, Lu Xuan estimated that their comprehensive combat effectiveness should be the innate thirteenth level A order.

For ancient martial artists, after entering the innate tenth level, it will become very difficult to move up each level, and the difference in strength between each level can be described as the difference between heaven and earth.

For example, the strength of the innate eleventh level is at least five times higher than the innate tenth level, and the innate twelfth level is ten times stronger than the innate eleventh level.

The higher up each level increases, the more exaggerated the change in power becomes.

Therefore, starting from the innate thirteenth level, there has been further refinement, and the innate thirteenth level has a total of three realms, A level, B level, is the primary level, B is the intermediate level, and C is the high level.

In the safety base, the three combat-type aliens who ambushed Lu Xuan were equivalent to the innate thirteenth-level A order of the ancient martial arts level.

Alien Empress, as the first

Debao's most terrifying existence, Lu Xuan conservatively estimated that its strength should be about the fourteenth level of the innate first.

And the strongest individual soldier of the Black Pages, Qiao Qiao's former partner, his strength is not lost to the existence of the alien mother emperor in Lu Xuan's calculations, and his strength is also between the thirteenth and fourteenth levels of the innate nature.

And Lu Xuan himself, the current strength is the 'Ancient Recipe True Qi' cultivation to the innate twelfth level, ** cultivation to the innate eleventh level, these two data "alone" is not eye-catching, but Lu Xuan's strength lies in the synthesis, he combined the true qi cultivation with the ** cultivation, not a simple addition, but a geometric multiple growth, basically close to the innate thirteenth level A level.

Lu Xuan had been able to easily kill three battle aliens with a strength slightly higher than him with a strength close to the innate thirteenth level A before.

It is completely because of his strong ancient martial arts, and the "hammering method" with domineering and overweight strikes as the core.

Although his ancient martial arts "hammering method" is extremely destructive, it is also limited by speed, and it is not difficult for Lu Xuan to annihilate the three combat aliens with the "hammering method" after mastering the proportions.

But if the opponent was the alien queen mother, or Cheng Haofeng, Lu Xuan would not dare to easily cast a domineering but slow thrashing method on them.

So for Lu Xuan, what is pressing at the moment is to improve his own strength.

Time is no longer waiting, and in the speeding train, Lu Xuan, who feels the urgency, makes an extremely bold decision.

The "Star Infinite System" in his body is different from normal, that is, there are two cores.

Lu Xuan's bold decision was to separate the other core and create a new Star Infinity System in his body, that is, to have two Star Infinity Systems exist in his body at the same time.

This decision was not only bold, it could almost be said to be extremely risky.

For hundreds of years, there were almost no ancient martial artists who had two True Qi systems in their bodies.

However, Lu Xuan has never been a reckless person, before he made this decision, he had already gone through countless calculations, and the success rate was 85%.

An 85 percent success rate is not low, but a 15 percent chance of failure almost means that martial arts are completely wasted and the risk of death is high.

After thinking about it repeatedly, Lu Xuan decided to take this risk, and for the sake of the future battle, he could only move forward.

First of all, he completely severed the connection between the "Xingchen Core Power" provided by the brain and the entire Xingchen system, and was supported by the "Xingchen Core Power" at the dantian alone.

The moment the dual core became a single core, the entire star system was greatly affected, and the operation of the stars slowed down rapidly, almost stagnating, but Lu Xuan, who had been prepared for a long time, did not let this stagnation last long, and by constantly absorbing the supplementary true qi stored in the **, the dantian core soon made the entire star system enter a state of equilibrium.

The power of the single-core Star Infinite System is ten percent lower than the original, however, Lu Xuan has calculated that after the second Star Infinite System is successfully built, the power of the two Star Systems combined is conservatively estimated to be at least more than twice that of the original whole.

After the old star system was stabilized, Lu Xuan quickly began to build a new "Star Universe".

The core of his second "universe" is still borne by the brain, but the energy points generated by the brain surround the heart.

That's right, Lu Xuan, who has already tasted the benefits of the dual-core true qi system, has created a new system that is still dual-core, the brain and the heart, to drive this new system together, and the power of the new system is at least three times more than that of the old system.

If the "starry sky" of the old system is white, then the "starry sky" of the new system spawned by the super dual-core is gold.

Around Lu Xuan's heart, thousands of golden energy points became clearer and clearer, and under the destruction of the familiar brain, they slowly ran around the habitual heart.

The second time he built the Xingyu system, the speed of progress was faster than Lu Xuan's own imagination.

In the process of running the energy point, it only took one-fifth of the time last time, an hour, to bloom into starlight.

A new dual-core "Star Infinity" was born.

Although it was only a first-order starlight, success came so easily that Lu Xuan couldn't help but have some doubts.

According to his previous calculations, the architecture of the new system should be relatively difficult, is this time because of his luck?

Lu Xuan soon found out that he was unlucky, and it was very bad, although the new system was very stable, the old system suddenly began to collapse!

If the old system completely collapses, it will set off a chain reaction, and the new system will never survive.

What should we do now? If we return the brain of one of the two cores of the new system to the old system, the new system will definitely not be able to keep it, and if we let the power of the heart add to the old system, I am afraid that it will cause an accelerated collapse.

Lu Xuan's principle has always been, he can't retreat, so go full speed, he gritted his teeth, then go further, and take the risk to the end!
