Following Ouyang Lan's footsteps back home, it was not only Xu Fei who was waiting for him at the table, but also Gege Ai Qingyi, who had already lost his family and identity, Xu Fei couldn't blame the culprit of all this, the expectant mother Xu Fei who was full of happiness.

After dinner, Xu Fei watched the boredom of the four beauties and began to play mahjong, he was very worried that his future baby would like the sound of rubbing hemp.

He looked at it for a while, and the notes on the faces of several girls began to grow, and he was bored and simply hid back in his office and remembered the abilities that the system had added;

Thinking of what kind of life space was forcibly deducted from 3,000 merit points after being the most reckless, what is that thing doing now, opening a farm or raising spirit beasts? He is on the earth, there is neither spirit grass nor spirit beasts, is it possible to grow cabbage in it to eat?

"Hey...... There are some strange things popping up in this system at any time, can't you give a detailed introduction, it seems that I have to ask Master in the future, this thing is so weird, it can still make people......" Xu Fei leaned back on the sofa and said lazily.

Just when he thought that creating man was the evolution of a machine, in a place in the system space that Xu Fei could not see, a three-legged tripod was slowly rotating, and a few tiny particles of dust fell from a large cloud of dark yellow soil in the air;

In a pool next to the big ding, a drop of water with the tip of a needle and the dust fell into the tripod, but in the middle of the big tripod was a drop of bright red blood, the dust and water droplets and blood beads quickly fused together, and then the blood beads began to tumble and continue to grow bigger.

And next to the system storage space, white lights are interspersed back and forth. A small bubble appeared first, and as one white light after another was thrown, the bubble also expanded rapidly as if it had been inflated.

Of course, Xu Fei couldn't see all this. He was bored for a while and began to plan, and each of the things that could be exchanged behind it would have a set of means of production and technical parameters, and if it was taken out, as long as someone who understood it learned, the explosiveness of this knowledge would be incomparably huge;

Just like those electronic products, transistors are still used in the world, but the integrated circuits of later generations have been developed for countless generations, and if they are manufactured now. That will make the technology of the world advance by leaps and bounds for decades.

Should things that are far ahead of this era be exchanged? Xu Fei struggled in his heart, he hadn't taken out the things that could promote technology and calculation in the computer before, because he was afraid that the explosion of science and technology would affect his plan.

"Forget it...... Or exchange those weapons and equipment from the late World War II for them to study. Isn't there now five third-level intelligences that can be exchanged, and I will exchange dozens of second-level intelligences and first-level intelligence, so that they can take those knowledgeable young people to learn and tackle key problems;

If this can quickly break through the barriers of technology and develop rapidly, then it proves that my worries are useless. But sooner or later, I'll have to exchange for that Nimitz-class aircraft carrier. It's such a big bunch of open and windy. ”

In the end, Xu Fei still didn't plan to exchange future high-performance weapons for the troops, but he was more lenient on military radios, and those radios were equipped with remote detonation devices, even if they fell into the hands of the enemy and were not detonated by the other party, he would remotely detonate them with radio waves, so at least that future technology would not be revealed.

The next day, there was nothing to do, and this place, which had become the military headquarters, became very lively, and hundreds of military personnel came and went and shuttled everywhere, which did not affect Xu Fei, and he spent a day recording the materials to be exchanged. At the end of his calculations, his remaining merit points were only enough to buy some simple and ordinary gadgets.

"It's half past six...... It's time to go in and see what's going on? Xu Fei, who had eaten dinner, sat on the sofa in the office and frowned.

"Attention hosts. The special artifact you wear cannot enter the system space unless you use your essence blood to make him make a preliminary confession and take it into your body. Just as Xu Fei was about to link the system to enter, the system's coquettish voice appeared directly in his mind.

"Why? Essence Blood Recognizes the Lord...... Okay, call up the inventory of essence blood to confess the master. Xu Fei said indifferently.

A ball of essence blood suddenly appeared in front of Xu Fei, he took the bell from his neck that he had bought for five cents from Beiping, and then reached out and wrapped the bell in a move.

"Buzz ......"

When the bell was covered in sperm blood, it began to vibrate automatically, trying to burst out of the sperm and blood mass, but it was like an invisible barrier around it, and it could only stay in place and keep vibrating.

"Squeak Squeak......"

When the essence blood merged into the bell, there was a slight squeak, and when all the essence blood disappeared, the bell swished into Xu Fei's body.

"Hey, this guy ran to the middle of the dantian to stay with him, what is this thing? The Shadowless Knife ran so far to hide, Nima, isn't it just a bell, the Shadowless Knife is a high-grade magic weapon, and at most it is a spiritual weapon, so it won't let him hide in the corner, right?

Could it be that this bell is still a fairy weapon? Quack Quack ...... is developed, and actually got a fairy weapon on the earth, can it be said that the immortals in the legends of the ancestors really existed? Xu Fei scanned his dantian with his divine sense and laughed wildly in his heart.

Xu Fei probed a few times with his divine sense, but there was no way to make contact with the bell, and he couldn't help but ask himself curiously:

"How does this thing work? Why can't I poke it with my divine sense? ”

"The host level is too low, and the divine consciousness can't even enter the first layer of prohibition, if you want to use the bell initially, the host should be in the primordial infancy." The system's voice suddenly spoke out after Xu Fei muttered to himself.

"Oh...... In this way, my level is still low, and I am also a tribulation or Mahayana master of those who have immortal weapons at every turn, and I am still a little person in the heartbeat period, Khan!

…… By the way, are you the administrator of the system? Can you solve my doubts? Xu Fei asked curiously after muttering a few words.

"I'm not a system administrator, I'm just the spirit of this merit exchange system, but I don't know anything about your exchange functions, and now I'm in the seal, and I need you to ascend before I can unlock the seal." The voice in the system was still speaking quietly and gracefully.

"Machine spirit, I've seen it in the novel, it's the soul of a high-level magic weapon, you don't know what the system is and what it does, so do you have a name?" Xu Fei blinked and asked inquiringly.

"The machine spirit doesn't have a name, can the host give me a name? As for the system exchange function, I can only know the things on a certain layer when the seal is unlocked, but if the host needs anything in the future, I can help you exchange it directly in the future, without you having to enter the system space in person. The timid voice that seemed like a little girl appeared in Xu Fei's mind again. (To be continued......)
