signed a contract to borrow 200,000 yuan again, and paid an advance payment of 10,000 yuan, Xiao Zhang began to upgrade overnight.

This time it is a large-scale upgrade, using the waste military robot provided by Li Minhao as the fuselage, using Gu Yueyang's waste mecha M4-grade alloy as an explosion-proof shield, supplemented by spare parts provided by Zhao Jinlong, and then renovating the disassembled core cabin, exporting all the memory chip source code programs of the cleaning robot, implanting them in memory chips with larger storage capacity and faster computing speed, and then using the dual-core excitation system to implant two sets of core cabins in each robot, making it a second-level combat robot in the real sense.

This only completes the preliminary work.

Next, more than 20 "round stool" robots began to shape each new "cleaner" variant, removing the masculine camouflage on the outside, smoothing out the edges and corners, and replacing them with more confusing and cute dazzling green cartoon pattern clothing, white on the top and green on the bottom, white shirts, green school skirts, foreign wigs, painted with curved eyebrows, and a group of cute robot girls.

The third step was Old Man Huo's turn, he activated the biological clock, implanted the photon density sensing program and the reflective detection program into the memory chip of the robot girl, and welded a positioning tracking chip and a panoramic information collection chip into the robot girl's body.

In the last step, Xiao Zhang implanted the high-energy particle detection program and the life force photon excitation program into the robot girl's memory chip, added several combat programs, and completed the entire upgrade process.

Xiao Zhang participated in the whole process, and under the teaching of the little old man, he made a robot girl by himself, through these operations, he quickly became familiar with the upgrade process, and also learned a lot of system design knowledge, which improved the level of mecha modification and robot production to a large level, and many source code programs that were originally incomprehensible also began to be integrated.

Tired and happy.

He loved the wonderful feeling of rapid progress.

He also made more advanced improvements to the 741, in addition to the military-grade fuselage and large-capacity photon rod, and put on a small mecha with a gold dress and gold skirt. This set of women's mecha came from Gu Yueyang's storage room, which should have been used by Gu Xiang'er, and was abandoned because the head armor was damaged. It took Old Man Huo a full hour to repair and modify it, and it was properly worn on the 741 fuselage.

In the 741 combat program, the overclocking photon system, dual-core excitation system, and golden ape rapid movement system have been added, and after this modification, its comprehensive combat effectiveness is as high as level four or above, which has far exceeded the power of ordinary second-level combat robots.

…

The night was hazy, and the first rays of dawn appeared in the east.

After a busy night, 101 all-round composite robot girls were neatly arranged in front of the A01 door, led by a blonde cute girl in a golden skirt, with the word 741 marked on the right hem of the golden skirt. The other hundred are little cute girls in white school skirts, numbered from 001 to 100.

Xiao Zhang and Old Man Huo each had a pair of panda eyes, smiling at their masterpieces.

The cute little beauty looked around the team, turned to look at Xiao Zhang, straightened her chest and abdomen, and said in a slightly hoarse voice: "Report to the boss, all the upgraded combat robots have been assembled, please instruct!" ”

"Ahem! 741, pay attention to the impact, you are still nominally a hard cleaner, not a combat robot. Moreover, you have not passed the test, and if you pretend to be a combat robot, you will be confiscated by the school. Xiao Zhang grinned.

The cute little beauty bowed slightly, and replied with her chest straightened again: "Yes!" We are cleaners, who are responsible for the sanitation of the campus and the boss in emergencies. ”

"Good. Go ahead, go back to your scheduled position, remember, if you are capable, you must take the cleaning work seriously, don't mess with me, and report to me as soon as you find out. Xiao Zhang waved his hand and couldn't help but straighten up.

The little beauty of the cute girl replied loudly, waved her hand at the little cute girls, and in a few flashes, she got out of the underground hangar.

It wasn't until the last little cute girl disappeared that Xiao Zhang withdrew his gaze.

"Dr. Huo, do you think that if Director Qiao knew that I had engaged in such a group of perverted super cleaners, would he have fired me directly?"

Old man Huo shook his head: "No." As long as you give him the 5A environmental protection certification, you have made a space robot, and he will not care about you. I still know a little bit about this little fat man, his character is not bad, he is not slippery, he is a little hard-working, and he is not eclectic, otherwise, he will not accept you to Harvard. ”

Xiao Zhang pondered for a moment: "Dr. Huo, you said that we have found out the reason for the decrease in photons, how can we improve it next, and how can we improve it?" ”

"Boy, let's take it one step at a time, increasing the photon content is a complex project that requires a lot of effort. At the same time, I expect that this time you will not face a fool like Hu Fugui, but an organized team, and it will not be so easy to defeat them. Okay, the old man is tired, and before dawn, I'll squint for a while. After Old Man Huo finished speaking, he yawned, fell into the beach chair at the door, and fell asleep.

…

Xiao Zhang hesitated for two seconds, then turned around and walked into his courtyard.

Pushing open the bedroom door, the girl in the silver dress had woken up, her dress was neatly dressed, most of the puffiness on her body had disappeared, the corners of her mouth were still cleared, her little head was lowered, her short hair covered most of her small face, and she was leaning on the edge of the couch, sobbing and wiping small tears.

Hearing the sound of the door opening, the girl in the silver dress raised her head in shock, shrunk her body, and tightened the corners of her skirt with her little hands, like a frightened bird.

"All right?" Xiao Zhang leaned against the door frame, tilted his head and asked coldly.

The girl in the silver dress was silent for eight or nine seconds before nodding her head.

"Okay, let's go back, I didn't close my eyes all night, and I'm sleepy." Xiao Zhang was very polite, and he was not ready to be polite to her, after all, this girl used to be full of hatred towards herself, who knows what her relationship with the little is.

The girl in the silver dress instantly turned red, trembled up, staggered a step, and walked to the door with her hands on the wall. It can be seen that although her internal injuries are fine, her qi and blood are vacuum, and she cannot recover overnight.

Xiao Zhang turned sideways, got out of the way, and watched the girl in the silver skirt bow her head and leave.

The girl in the silver dress walked to the door, suddenly stopped, bit her little lip, turned around and bowed to him: "Thank you for saving me!" ”

"There's no need, it's because I'm soft-hearted and cheap, and I can't look at the dead. Come back, I'll give you another word of advice, don't follow the little, that's not a good thing. Xiao Zhang waved his hand and sneered.

The girl in the silver dress gritted her teeth and nodded, and said angrily: "Yes, he is a beast!" I listened to his nonsense, fell into his trap, and finally harmed others and myself, I, I confess to you! ”

Xiao Zhang's face stretched a little: "Well, it's good to understand." It's not too late to regret it now, go back and study hard, in terms of your qualifications, in the third year of high school, few people are your opponents. ”

After listening to Xiao Zhang's words, the girl in the silver dress relaxed a lot, and her mood was much better, she wiped the tears on her face with her skirt sleeves, and floated a little smile: "Xiao ...... Senior, my name is Jiang Yue, do you know how my brother and Xue Fei are doing? ”

"Oh? Who is your brother? Xiao Zhang was slightly stunned. Xue Fei knew that in the alleyway of the Eastern District, Xue Fei was sitting on the second blue-armored locomotive, and his arms were unloaded with a photon cannon.

"His name is Jiang Zhou, a student in the second (1) class of high school, and he is the leader of the blue-armored motorcade......" Jiang Yue said weakly.

Xiao Zhang stroked his forehead and quickly guessed who Jiang Yue's brother was.

It should be the man on the first blue-armored chariot who has been chasing his ass, but that guy seems to have been beaten down by himself, and he also hit the parapet, and the death or injury is unknown, and it is estimated that the situation is worse than Xue Fei.

Seeing that Jiang Yue had been staring at him, Xiao Zhang shrugged his shoulders and said indifferently: "Your brother chased me too fiercely, and finally crashed into the protective wall of the isolation belt, I don't know the specific situation." As for Xue Fei, he was shot twice by me, and he was greeted on the arm, and he didn't die again. I warned him on the three-hall arena, and I saw him deal with me again without mercy. ”

Jiang Yue's little face turned white instantly, bowed to Xiao Zhang, covered her little face and turned around and ran out.
