The old man who was grabbed by Luo Hao slapped Luo Hao's hand, took out two colonel collar badges from the pocket of his white coat, and pretended to be angry and said: "You kid is not big or small, but I am also a two-haired four!" ”

"Yes, Director Zhang!" Luo Hao hurriedly stood up and saluted.

However, this short solemnity did not last for a few seconds, and Luo Hao and the colonel laughed at the same time.

The colonel, who was called "Director Zhang" by Luo Hao, nodded at Luo Hao and scolded with a smile: "You slippery head, you are still so naughty!" ”

Luo Hao hooked the colonel's shoulder, introduced Zhou Bai, Xu Xudong, Situ Kong, and Li Yifeng, and said, "This is Lao Zhangtou, the head of the research institute. ”

"Hello Chief!"

Zhou Bai, Xu Xudong, Situ Kong, and Li Yifeng hurriedly saluted the colonel.

The colonel waved his hand at the four people and said, "Don't be so restrained, you just like Luo Xiaohao, just call me 'Lao Zhangtou', everyone in this institute calls me that." This kid and I are not old or small, I am used to it, anyway, I don't take my two cents and four as an official, my two collar badges are in my pockets more than the time on the collar, and it is estimated that I am the most unseemly colonel in the whole army. ”

"Where can I be? I have a lot of respect for you. ”

Although Luo Hao said this, his hand still hooked Lao Zhangtou's shoulder, and said to Zhou Bai, Xu Xudong and the four of them: "Lao Zhangtou is very good at light weapons research, you can mention it to him if you have special weapon needs, but remember to bring good wine and good cigarettes when you come." ”

"It's good to drink and smoke?" Lao Zhangtou flicked on Luo Hao's head, made a tiger face, and said: "You kid has taken me from childhood to adulthood, how many treasures have you taken from me, and have you ever given me good wine and cigarettes?" ”

"Isn't that owed?" Luo Hao replied with a smile.

"Owe!? Say more every time! ”

Lao Zhangtou looked at Luo Hao, blew his beard and glared: "You kid said by himself, how much cigarettes and how much wine do you owe me?" ”

Luo Hao scratched the back of his head, smiled dryly, and didn't answer. Every time Luo Hao came here to get something, he said that he owed it every time, and he couldn't remember how much he owed.

"Old Zhangtou, what good things do you have for me this time?" Luo Hao just wanted to reach out and pull Lao Zhangtou's beard, but before his hand could touch Lao Zhangtou's beard, he slapped it away with his hand and said, "I really prepared something good for you this time, and everyone has a share!" ”

Hearing Lao Zhangtou's words, Qi Fan and Chen Yingtian couldn't help but raise their eyebrows slightly, because they knew that what Lao Zhangtou took out in his hand was definitely not ordinary.

Lao Zhangtou took more than a dozen people directly down to the second floor of the institute by elevator, located in the second floor of the institute ten meters underground, everywhere you can see the staff of the institute wearing goggles and white coats, when they see Lao Zhangtou, they will stop and nod hello to him, and these staff members are also called "Lao Zhangtou", not "director", or "chief".

Lao Zhangtou took Luo Hao and the others into the research institute on the second floor, a room enclosed with bulletproof glass, and two silver-white metal suitcases were placed on the table in the room.

Lao Zhangtou asked Luo Hao, "Luo Xiaohao, do you remember the katana you brought in last time for me to study?" ”

After the two unusually sharp short knives were brought back from Nanxian Kingdom and handed over to the research institute for study, Luo Hao gradually forgot about them, and now that Lao Zhangtou mentioned this, Luo Hao remembered it. Looking at Lao Zhangtou with some surprise, he asked, "Have you researched it?" ”

Lao Zhangtou had a tiger face, and said a little unhappy, "What is this called?" Who am I? The person in charge of the Longyin Army's Weapons and Equipment Research Institute is not in vain! ”

Lao Zhangtou opened a metal suitcase, took out a fighting saber with a scabbard from it and threw it to Luo Hao, "This is the new dragon tooth saber, are you still satisfied with it?" ”

Luo Hao pulled out the newly created dragon tooth saber from the scabbard and looked at it in his hand.

The new Dragon's Tooth Saber is no different from the original Dragon's Tooth Saber in length, with a hollow handle that allows you to place a medicine box, and after the medicine is used, you can pull out the medicine box, attach a folding steel rod, and use the knife as a spear.

The new Dragon's Tooth Saber has a pitch-black blade, and even the blade position is black, just like the black Seal Flower Short Knife. Although he couldn't see the blade of the saber, Luo Hao didn't doubt the sharpness of the knife in his hand at all. And on the body of the knife, Luo Hao's action code is also engraved with a laser, Crazy Dragon!

"Although they don't have a good impression of the country of Neon Country, their forging skills in cold weapons are really good!"

Lao Zhangtou also took out a saber from the box, played with it in his hand, and said: "After research, we found that it is not simply made of metal, but also mixed with some special ore components, and after analysis, this composition comes from volcanic lava, which can make the blade harder and sharper!" However, the ore of this volcanic lava is very difficult to refine, even if the entire working group works day and night in three shifts, only 500 grams of this special ore can be extracted, but fortunately, before you set off on this mission, your dragon's tooth saber was made. ”

"How much has this new Dragon's Tooth Saber improved from before?" Luo Hao took the knife in his hand and asked.

Lao Zhangtou took out a solid steel rod the thickness of his little finger and handed it to Luo Hao, "Just try it." ”

Luo Hao held the dragon's tooth saber in his forehand and slashed it against the steel rod, only to hear the sound of "dang", one end of the steel rod was directly cut off by the knife, and the incision was smooth and flat, but on the other hand, the dragon's tooth saber in his hand was not damaged in the slightest!

"Good knife, really good knife!" Luo Hao was overjoyed. His original Dragon's Tooth Saber was lost in Wanagoga, and now he fills the gap in his melee weapons.

Luo Hao put the knife back in the scabbard and asked Lao Zhangtou, "How is that ninja suit?" ”

"Difficult!"

Lao Zhangtou frowned slightly, and said: "That thing is more complex than a knife, it will take a while to study it thoroughly, the only thing that can be determined at present is that the ninja suit is definitely not an ordinary plant fiber fabric, if you can study its composition and then apply it to body armor, you can maintain the current performance of body armor, the quality of the body armor we are equipped with will be greatly reduced, and it is more likely that it will be made into bulletproof camouflage clothing!" ”

"Old Zhangtou, if you tell me about this kind of thing, I don't understand it, and the research will be all handed over to you anyway." Luo Hao hooked Lao Zhangtou's shoulders and said, "Next time, I'll bring you good cigarettes and wine." ”

Lao Zhangtou pursed his lips disdainfully and said, "I don't care about your kid's good cigarettes and wine, just get me some treasures for me to study next time." ”

"Deal!"
