"I don't know if there are many missiles, I remember that I used a lot of them half a month ago, and if I consumed them halfway, I may not be able to stop these zombies for long."

Clusters of firelight rose in Lu Tian's eyes, all representing that the weapons of the base were disappearing little by little, turning into light and heat, ending its life in a few seconds.

In addition to the previous ones, Lu Tian quickly collected more than 2,000 orange energy points, which was also the first time that there were so many.

"Xiao Qi, how long will it take for space debris to be refined?"

"It's going to be about ten years!"

Lu Tian shook his hand and split a zombie in half, indicating that he was in a bad mood.

"Xiao Qi, if I consume energy, can I speed up the refining speed of space debris a little?"

"Yes, but it's costly, and it's not worth it for the owner at the moment."

Lu Tian was a little surprised, he didn't have enough energy points before, of course he wouldn't think about it, but now he asked casually, it's really okay.

"Tell me how to calculate it!"

He was in a hurry.

"10 orange energy points can be reduced by about one day, and the better the consumption, the greater the consumption, the reduction will be 5,000 in the first year, and the cost will double every year after that, that is, 10,000 in the second year, 20,000 in the third year, and then 40,000, 80,000, master, you need at least more than 155,000 orange energy points to reduce the time by half, if you want to completely refine, at least 5,115,000 orange energy points or even more, this is 5 points of cyan energy, does the master know what this concept is?"

"What concept?"

"This is equivalent to the power of a god, enough to buy hundreds of living planets like the earth."

Xiao Qi is right, it is indeed a bit difficult to use these energy to accelerate the formation, but he can't use these energy points for the time being, why not use the extra energy points on this, this is a long-term investment.

"Is there more energy on Earth than that now?"

"Of course, the power contained in the center of the earth alone far exceeds this number, the total amount of vitality between heaven and earth also exceeds this number, and even the energy contained in the crystal nucleus of the Huaxia zombie also exceeds this number, but it is difficult for the master to collect so much energy alone. Wouldn't it be nice to wait ten years for the owner to do it without other consumption? ”

Although Xiao Qi said this, he thought about it, and decided to use the energy points on it, this is not his eagerness, but a long-term problem, if he can solve this trouble as soon as possible, maybe he will be able to earn these back in a few years.

"Xiao Qi, how much time can 2000 orange energy points be reduced?"

"180 days, about half a year."

Xiao Qi didn't persuade again, it lived a long time, and he didn't quite understand why the owner couldn't wait for just ten years, and this time it usually took a nap and passed.

"Okay, use it directly, and then tell me how long it will take to succeed in refining!"

"Yes, master. Drops ~ consume 2000 orange energy points, leaving 16.1111 orange energy points. ”

Then Lu Tian got some information, knowing that the energy stored for more than half a month was gone in an instant, and his heart twitched slightly, fortunately, this is not money, and he will not go to eat soil.

However, thinking that the war was not over here, and he should still be able to get a lot of energy that met the standards, he quickly put this depression aside.

"Master, there are still 3,500 days, 11 hours, 20 minutes, and 41 seconds before the end of space debris refining."

"Yes, it's a twentieth reduction, and it's good to take the first step."

He was not afraid of a long time, he was afraid that there would be no end, and now that he knew how to speed up the refining speed, of course he would not be discouraged.

"Xiao Qi, can consuming your shot reduce the time?"

"No, this is the seal left by the old master, Xiao Qi doesn't dare to move, everything can only rely on the master himself, this is also what the old master meant at that time."

Lu Tian was slightly disappointed, and he didn't think much about it, there are some things that can't be relied on by others.

"It's a pity that I don't have a doppelganger technique, otherwise I can go to other parts of the base and even other bases to collect energy."

Lu Tian sighed, if he could go to the provincial capital or even the former first-tier cities to collect energy, he would definitely be able to speed up greatly.

"Yes, master, why can't you be separated?"

Xiao Qi heard Lu Tian's words and expressed his objection.

"I forgot that you have a lot of things here, do you have one gas and three clears?"

He also came to be interested, this Xiao Qi has the information of the endless universe, it is an unimaginable treasure house, and it is estimated that he has not even finished reading the tip of the iceberg.

"This is the top Taoist technique in Chinese mythology, Xiao Qi does not have the original version here, but there are many of the same effects, not only can be turned into three, but also into four and five into thousands of thousands, that is, the master of your realm is not enough, and you can't cultivate."

Sure enough, this little seven is lazy, and rarely takes the initiative to say the good things he has, so he has to rely on himself to discover them, or remind them in turn.

"Since there are those who can't cultivate, there must be those who can be cultivated, right?"

"Well, Xiao Qi recommends cultivating the art of puppetry, the requirements are relatively low, and there are raw materials."

"Puppetry? The raw material can't be these zombies, right? ”

Zombies don't have many brains, and they seem to be the best thing to control.

"Well, puppetry is a cross between the way of cultivation and the way of technology, according to the meaning of the earthlings, it is also one of the three thousand avenues, it is similar to and different from pure technological robots, because this thing can only be produced by cultivators, and technology alone will not work."

"It's a product between two extremes, if the puppet evolves to the point where it can be cultivated, it can be classified as a cultivator, and if it is only pure rational, it can be regarded as a programme-controlled machine, so it has a wide range of applications, and it is very popular in that kind of civilization."

"Puppets can be classified according to autonomous consciousness, and those that do not have a little autonomy are similar to robots, the higher the autonomous consciousness, the better their flexibility, and if they reach 100%, they will be similar to the Transformers that the owner knows."

"The other classifications, like many other things, are also classified by power, powerful puppets are stronger than gods, and weak ones may not be as good as ordinary humans on earth."

"According to the degree of processing, it can be divided into natural, primary processing, and deep processing, according to the form, it can be divided into beast-shaped, insect-shaped, and human-like, according to the role, it can be divided into combat type, household type, and according to the applicable environment, it can be divided into land combat type, air combat type, space type, underwater type, multi-functional type, and ......"

Xiao Qi talked for more than ten minutes, Lu Tian killed dozens of zombies, and the missiles in the sky were also consumed about the same, so he only talked a little about the introduction of the puppet, seeing that Xiao Qi still wanted to say something, Lu Tian had to open his mouth to stop it.

"Xiao Qi, don't talk about it yet, pass those materials to my head, I'll read it myself."

"Oh, master, this is a new road, master doesn't need to pay too much attention, avoid distraction and waste of time, just understand it."

"You can introduce the kind of puppet technique that suits me, isn't it going to use zombies?"

"This kind of puppet technique is most suitable for the current situation, and the owner only needs to select the zombies that meet the requirements, and then you can use it."

"What are the conditions, can these ordinary zombies be?"

"No, ordinary zombies can't withstand the master's puppetry, they must be advanced, at least above level three, and the more advanced the better, so the success rate will be higher."

"How many energy points do I need to redeem?"

"200 orange energy points."

"I should have left a little bit just now."

Lu Tian said with some pity, if he exchanged it now, he could have studied it earlier.

"If I succeed, it seems that I can only kill zombies to collect energy cores, Xiao Qi, can you absorb energy through puppets?"

"Yes, but there will be an additional 10% processing fee."

Lu Tian cut off the three zombies that climbed up with a single sword, and it seemed that he had been killing zombies all the time and would not attract the attention of others.

"Why can it be absorbed by a puppet, can't you only absorb energy within a 2 km radius?"

"I am based on the master's spiritual power, and I can absorb wherever the master's spiritual power can reach."

In other words, if you can control the golem to run to other bases, you can also collect energy.

"Well, I see, let's wait until the war is over to do it, I don't think I can finish it in a short time."

Lu Tian is not in a hurry, now he still has a task, and he can't get out of it for the time being.

The helicopter gunship in the sky stopped for a moment, then turned around and headed back.

The light of the fire gradually decreased, the sound of the explosion also disappeared, and the howl of the zombies took over again, and the sky gradually brightened, and the silhouette of the distance could already be seen.

There is still a large black shadow approaching, all zombies, the missiles just now could not scare them, nor did they stop their steps, the zombies are still continuing.

"Everyone be careful, a new wave of zombies is coming."

Yun Ding's face was tired, and he understood that he couldn't bear it.

The zombie hordes didn't use any tactics, they kept piling up with numbers, just with this one method, how could a mere line of defense be stopped.

The battle between the two sides entered a white heat, and the city walls were full of zombies, and the speed of climbing up gradually exceeded the speed of killing.

Bang~

There was a muffled sound, something smashed on the city wall, Lu Tian turned his head to see that several big guys were mixed in the zombie group, picking up things in their hands and throwing them on the city wall.

Mutant zombies have finally appeared!

The screams came one after another, and one by one the soldiers were killed by the speed-type mutant zombies hiding in the ordinary zombie group, the fire suppression was reduced, and more zombies climbed the wall.

One by one, the power-type zombies ran to the city wall, and did not climb up, but kept hitting the city wall, their strength was greater than that of a cow, and they didn't know that they were tired, and the city wall began to crumble.

Rumble~

A violent explosion sounded beside him, and several soldiers and the transcendents next to him were smashed into bloody mud by a piece of concrete, and a two-meter-high mouth in the distance still maintained a spitting posture.

With the assault of mutant zombies, the entire defense line is in chaos. Especially the guy who hits the city wall is the most threatening.

"Gotta kill those big guys, don't let them knock them out!"
