When the Unicorn starship approached the earth, the starship had actually received a lot of identification signals, some from the Atlanta Federation military, and some from the governments of the earth, but Lu Fan did not respond to these identification signals out of consideration for the overall situation, and even let the Unicorn starship enter a stealth state, before sailing into the northern hemisphere of the earth's atmosphere and flying towards the direction of the Taihang Mountains.

Flying over the eagle falling cliff, looking down at the deep cliff from 10,000 meters above, you can still see the mist that does not disperse all year round shrouded the bottom of the cliff, and the whole cliff valley is dressed up like a dream, like a mysterious realm like a fairy valley.

The surface is illusory, and the valley below the fog layer is in the low world, Lu Fan has already seen it, it is just a bone world, and its true face will only make people tremble when they see it.

The huge hull of the Unicorn naturally couldn't fly directly to the bottom of the cliff, so Lu Fan had to choose to enter the underground base with Auberding and join Auberdin's real body.

Lu Fan blocked Medusa's idea of wanting to follow, feeling that it was unnecessary and a waste of time, at the speed of him and Auberdin, hundreds of kilometers deep underground, it was only a few breaths.

Climbing into the cabin of the Silver Wing, the fuselage that is now only more than three meters high, just a few ups and downs, it went deep into the white fog that could not be seen, and the gray world realm of the brain also sensed that Auberding was following closely behind the Silver Wing, and it also penetrated the dense fog.

The second time he came to Lu Fan, he was familiar with the way, and after landing at the bottom of the cliff, he didn't even look at the dry bones and remains that had remained unchanged for ten thousand years, and directly found the slender passage and jumped down.

When Lu Fan first entered the underground base of the Holy Spirit Empire, he entered in the flesh. There were also many accidents during this period, and this entry, because the Silver Wing had shrunk to a size of three meters, it was naturally much easier to enter the passage, and what he didn't expect was that the Silver Wing had just jumped into the passage, and there was a clear and palpable tremor. Through the hatch, you can see that the limbs of the Silver Wing squirm rapidly, and then instantly turn into a sharpened shape like a bullet. After sliding in, head underground.

Lu Fan was a little surprised, after Lisa tinkered with the Silver Wing. I actually put my own body in, and the effect is really good, and it can almost be called a change from the heart, similar to the existence of a transformer.

A little touched by Lisa's sacrifice, but Lu Fan sincerely believes that since the body had a breakthrough last time, the role of the mecha has become dispensable, and often piloting the mecha is just a habit that Lu Fan can hardly suppress.

In a matter of minutes, the bullet-like body of the Silver Wing had reached the deepest point of 100 kilometers. The familiar eerie bronze coffin scene instantly rushed Lu Fan's eyes.

In the past, Lu Fan was still a little curious about these tightly sealed giant bronze coffins, but after learning that they were only containers for the Holy Spirit Empire's cultivated creatures, this curiosity was extinguished. All that's left is that caution.

Holy Spirit Empire Biological Base, intelligent life, these two words add up, it does not mean that it is Lu Fan's trust, on the contrary, some manifestations of Oberding's clone. He couldn't help but be wary.

If it is an intelligent life, it will have selfishness and live alone in the ground for tens of millions of years, although because of the program arranged by the Holy Spirit man, it cannot come out freely, but it does not mean that it has no ideas.

Finding an opportunity to get out of trouble is the simplest reason, and this opportunity may be on Lu Fan, which can be seen from the performance of Auberdine along the way.

No matter what Auberdine had in mind, Lu Fan's purpose in coming to the biological base was just to understand the background information of the original battle with the Holy Spirit Empire in the universe and the last time he was driven out of the galaxy enemy.

If Auberdine only wanted to get out of the biological base, Lu Fan would even help within his ability, but not secretly as he did now. …,

Lu Fan also knew that Auberding had mentioned before that only if the Holy Spirit Power in his body reached a certain standard, he would naturally be recognized as the owner of the base, which had been set by the Holy Spirit Empire in ancient times.

But for the improvement of the Holy Spirit Power, Lu Fan hardly has any targets to refer to, and he has no systematic cultivation materials, so he is undoubtedly fishing for the moon in the well by groping on his own.

At this time, Auberdine behind him had already walked up to Lu Fan silently, and said, "Lord Holy Spirit, I have already made contact with the main body in the base, and the arrival of the 'Hades' has already known the Dao, but since you are not nearby, it can't make an accurate choice." ”

"Hades?"

"Is it an unknown enemy from the Silver Heart?"

"Lord Holy Spirit, yes, because they come from darkness, and the Holy Spirit Empire calls them 'Hades.'"

Now that Auberding has made contact, there is no need for Lu Fan to enter the center of the base, as long as he gets the information of the 'underworld', this underground trip will be considered a successful completion.

"Can I pass them on to Lisa?"

"No problem, after the 'Hades' appeared, the base body has activated the emergency permission, and it is completely possible to copy these materials to you, and please wait a while, Lord Holy Spirit, I will connect to the base mastermind database." Auberdine walked to the vicinity of a copper coffin with an expressionless face, and pressed one on the coffin surface, and in an instant, mysterious characters lit up on the coffin surface, floating up and down Oberding's arm.

When he was young, Auberdine greeted Lu Fan and asked him to drive the Silver Wing to the side of the giant bronze coffin, and put his other hand directly on the shell of the mecha.

"Master, I have accepted the information of the 'underworld', and there are also some methods of the Holy Spirit people to deal with the 'underworld'."

"See how the 'underworld' is dealt with in the data?" Lu Fan asked hurriedly.

"Master, wait a minute, it will take a while to decipher the words of the Holy Spirit Man."

"Well, let's go back to the ground first." Lu Fan manipulated the Silver Wing and turned around and left the underground hall full of giant containers, and swept towards the entrance of the cave where he came.

"Wait, Lord Holy Spirit!" Auberdine called out sharply behind him.

Stopping the mecha's flying footsteps, Lu Fan turned around and asked, "What's the matter?" ”

"Lord Holy Spirit, Auberdine will not go out with you for the time being this time, because with the arrival of the 'Underworld', I will definitely let the main body improve some combat capabilities, and soon, I will automatically come to Lord Holy Spirit." Oberding rarely bowed to Lu Fan and said respectfully.

Lu Fan didn't care if Auberdine had any secrets, nodded calmly and said, "Okay, after the transformation, come to me by yourself, and I will stay on the earth for a little time." ”

"Definitely! Lord Holy Spirit, the base already has a code to identify the Unicorn, and as long as Lord Holy Spirit does not leave the earth, I can find Lord Saint at any time. ”

"Hmm......" Lu Fan didn't say anything more, and directly drove the Silver Wing out of the passage, and after breaking away from the dense fog at the bottom of the cliff, it didn't take long for him to return to the unicorn hovering over 10,000 meters.

After the Silver Wing was reduced, whether it was flexibility, mobility, or ease of operation, it was much stronger than at the beginning, which made Lu Fan even have an illusion, as if the Silver Wing was an extension of his body. Of course, this is Lisa's role as a mecha shell, the mysterious metal command has a hearty performance, which has been exerted by Lisa to the extreme, coupled with the fact that Lu Fan's master and servant have the same mind, which makes Lu Fan in many cases, he doesn't need to work hard to control the mecha to run, and the armor moves at will, which is the state of the Silver Wing at the moment.

However, this still failed to make Lu Fan feel convenient, in fact, after having the crystallization ability of the Jingyuan clan, Lu Fan already thought that auxiliary vehicles such as mecha were likely to become a burden in the future, and the combat time of taking a mecha was undoubtedly much longer than that of the physical body, but every time Lu Fan fought, there was always a feeling of unfinished business. …,

Lu Fan had an idea, so he simply gave up the mecha and let Lisa wrap it directly around him, becoming a auxiliary armor that could be used at will, so that he could not only use the indestructible crystallized spear, but also use Lisa's characteristics to surprise the attack.

Walking into the command center of the Unicorn, a pair of expectant eyes swept over together, and Su Mei and Sunset rushed directly to Lu Fan's side and asked anxiously: "Lu Fan, how is the situation?" ”

"It's going well, I've gotten the information of the Silver Heart's enemy from the main body of the biological base, Oberding, Lisa is deciphering the Holy Spirit text, everyone be calm, there will be an answer in a while." Lu Fan waved his hand and pulled Sunset and Su Mei back to his command chair, and the two of them sat on the seats next to them.

"Zhilu said that you are anxious, why am I not! But I will still think about it from the good side, as you all know, the federal government, for the sake of my face, would have kept the list of your relatives secret, so that in case of emergencies, it could be prioritized. ”

"Lu Fan, even the Federation can't do anything, so in the end we can only choose to retreat, we are still worried."

"I'm still worried about Jiang Yu and Jiayi, are they in a hurry? Only by finding the coordinates of the retreat of the Federation will it be possible for us to look for them. Lu Fan sighed and said with a gloomy face.

"Didn't the Federation leave a lot of guard mecha troops with them? Will they know the truth? Sunset stretched out her hand to block Su Mei's exit, and asked Lu Fan in a tactful tone.

"You've also seen the Federation starships that have stalled outside of space, and there is no record of them even on the destroyers responsible for tail sweeping! During the war, the Atlanta Federation still had a strong secrecy about the retreat coordinates, and only by finding a backup shelter could the coordinates encrypted by the Federation be found. ”

Lu Fan breathed a sigh of relief, and then said: "Now, the guard mecha troops left on the earth may be a plate of scattered sand, and we must find it, but we can't waste time, and after Lisa finishes deciphering the information obtained from the underground base and is fully prepared, we will act." ”

"Auberdine didn't mention the Unknown Enemy at all?" (Your support is my biggest motivation.) )
