"Are you free for the evening? Last time I had something to ask for leave, please help me take care of the experiment, I haven't had time to thank you, I'll treat you to dinner in the evening! Sun Chengli's face remained unchanged, and he immediately found another reason to invite Shang Ke to dinner.

In modern society, beauty is a scarce resource. Not to mention this kind of beauty who devotes herself to science and engineering and works in a laboratory.

As long as there is the slightest possibility, Sun Chengli will not let go of the opportunity to be courteous.

"No need, I was just a gesture last time, in fact, Bei Yang mainly helped you take care of it, if you want to invite him to dinner, just invite him!" Shang Ke had a smile on his face, but he refused very simply.

Sun Chengli glanced at Bei Yang next to him, and a trace of unhappiness flashed in his eyes.

"It's okay, let's go together, it's just going to be lively!"

Although he was unwilling to spend money to invite Bei Yang to dinner, Sun Chengli knew in his heart that if he didn't call Bei Yang together, Shang Ke would not agree to his invitation at all.

It's just a small experimental assistant, and it shouldn't affect his plans to pick up girls.

"Yo, I've heard someone outside that someone wants to invite you to dinner, who wants to invite you to dinner?"

At this moment, the door of the laboratory was pushed open again, and a beautiful woman walked in from the outside, wearing a red checkered long-sleeved shirt on a white background, a short black skirt underneath, long hair with a shawl, orange lips slightly curled, as if smiling, and a pair of eyes like water waves.

Standing next to Shang Ke, it is like two pearls, reflecting each other.

Seeing the two girls standing together, Sun Chengli's expression was suddenly stunned, obviously amazed, and Bei Yang on the side couldn't help but look up more.

The girl who just came in was named Tang Ya, Shang Ke's best friend, the two were classmates in college and graduate school, and now they are working in another biology laboratory in this building, so they often come to Shang Ke.

"Last time I asked for leave, thanks to Shang Ke and Bei Yang for helping me take care of the experiment, so I want to invite them to dinner to express my gratitude, Tang Ya, do you want to go with you?" Sun Chengli asked with a smile.

Tang Ya's posture is not inferior to Shang Ke, Sun Chengli is very happy to invite her to have dinner together, maybe the east will not be bright and the west will be bright, if you can't catch up with Shang Ke, it will be good to be able to catch up with Tang Ya!

"I don't have time, you guys go eat by yourself!" At this moment, Bei Yang on the side spoke.

After finishing speaking, Bei Yang turned around and walked to the side.

Although it is pleasant to eat with two beautiful women, it is not so pleasant to be used as a gunman.

Seeing Bei Yang so faceless, a touch of annoyance flashed in Sun Chengli's eyes.

"Sun Chengli, it seems that your meal is not delicious! In this case, then Shang Ke and I won't go, we have to go to the world of two tonight! Right, baby? Tang Ya put her arm around Shang Ke's shoulders and said with a smile.

Shang Ke swung his shoulders and broke away from Tang Ya's hand, his face was slightly red: "Tang Ya, what nonsense are you talking about!" ”

Then, Shang Ke turned his head to look at Sun Chengli again: "I'm sorry, I may not have time to ...... tonight."

"It's okay......" Sun Chengli smiled reluctantly and walked away.

"The toad wants to eat swan meat and chase my baby, but it's still far away!" Looking at Sun Chengli, Tang Ya muttered quietly, and then she turned her head to look at Shang Ke, with a smile on her face that was not bad and kind, "Come, let my husband take a bite!" ”

"Don't make a fuss! I'm going to work! Shang Ke patted Tang Ya's forehead and said angrily.

Tang Ya talked to Shang Ke again and left, after all, she also had to go to work, and she couldn't stay in this laboratory all the time.

In the corner of the laboratory, Bei Yang was sitting on a chair.

"Although I already have special abilities and items now, I am still just an ordinary person, and I will be injured and killed, compared to the iron armored corpse, my body is too fragile."

Bei Yang looked at the small wound on his right index finger and thought silently in his heart.

Just now, when he was sorting out the broken test tube, he suddenly felt a pain in his fingers, and when he raised his hand, he found that his fingers had been cut.

He can manipulate the iron-armored corpse to break through a wall, but he is so fragile that even the glass can cut through his skin, this obvious difference makes Bei Yang feel a sense of urgency for his own strengthening.

"There are runes to strengthen the puppet in the puppet technique, and there are also means to strengthen the zombie in the alchemy, but these two methods, the puppet technique strengthens some dead things, and the alchemy strengthens only the corpse, and it must not be directly used on myself."

"Now I don't have a puppet in my hand, the puppet enhancement rune will be talked about later, now let's study the enhancement methods in alchemy for the time being."

Soon, Beiyang identified the top priorities for now.

That evening, in the laboratory.

Everyone else had already left work, and Bei Yang stood in front of the experimental table, holding a blade in his hand, and an iron-armored corpse wearing a Qing Dynasty official uniform stood next to him.

He planned to cut some flesh from the iron-armored corpse, slice it and observe it, compare it with normal human cells, and see if he could use the methods of alchemy on living people.

Bei Yang held the blade between his two fingers and slashed across the arm of the ironclad corpse, but not to mention the wound, there was not even a white mark.

Seeing this result, Bei Yang's brows furrowed, and he once again grabbed the blade and cut at the arm of the iron-armored corpse, this time his strength increased a lot.

Syllable!

With a crisp sound, the blade in Bei Yang's hand broke in two, and there was still no scar on the arm of the iron-armored corpse.

Looking at the dark and shiny body of the iron-armored corpse, Bei Yang thought for a while, and as soon as his mind moved, there was suddenly an extra wooden sword in his hand, which was the hundred-year-old peachwood sword.

With a wave of the peachwood sword in Bei Yang's hand, it slashed directly from the arm of the iron-armored corpse, and a small piece of meat flew directly from the iron-armored corpse's body, and at the same time, the iron-armored corpse also let out a low roar of pain.

After waving his hand to put away the iron-armored corpse, Bei Yang picked up the piece of meat with tweezers, cleaned it, and put it in a petri dish.

Cut off a little bit with a mahogany sword to use as experimental material, and set the rest aside and save it.

Subsequently, after several treatments, Bei Yang made several temporary mounts of this experimental material and observed them through a microscope.

Under the microscope, all the cells on the mount were transparent and colorless, and none of the cells were stained.

The cells are not stained, which is a manifestation of living cells, but these cells are derived from the ironclad corpse, which is a corpse that has been dead for more than twenty years.

"Because of some mysterious factors, are the zombie cells still alive?" A thoughtful look flashed in Bei Yang's eyes.

Immediately, he took a piece and placed it on the mahogany sword, and after a few seconds, he re-stained the piece, and as a result, all the cells were stained.

This means that all the cells on the mount are dead!
