Although he was not worried about zombies, Chu Bai quickly checked the other rooms, there were no zombies in the billiard room, and there were eleven in the game room. All the zombies were obediently cowering in the corner, even if Chu Bai walked in front of them and raised the butcher axe, he still did not resist. Chu Bai didn't kill them, but cut off the zombies' hands and dragged them all to the table tennis room.

"Why do you still have two heads?" Yun'er helped Chu Bai move ten zombies to the table tennis room, and Chu Bai didn't care when she saw that there were still two zombies in the game room.

"Ten heads are enough, you go and kill those two, hurry up." Chu Bai had enough of the zombies and began to look at the patterns on the box.

"Oh. Although she was confused, Yun'er obeyed Chu Baiyan. Trotting to kill zombies, she has become obsessed with the refreshing feeling of killing zombies.

"Be sure to open an energy card, preferably with this knife." Chu Bai looked at the ten square spaces on the stone box, and stared closely at the black card in one of the spaces.

Soon Yun'er came back, with a satisfied look on her face, looking at the ten zombies lying on the ground.

"Don't think about these ten, it takes ten points of energy to open the welfare treasure chest once, and a zombie only has one point of energy. These ten heads can be opened just once. Let's look at it next. Chu Bai quickly opened the scoop of the ten zombies, the boxes flickered one after another, and the ten spaces flashed with a burst of golden light, and a pack of Kang Shuaifu instant noodles was suspended in front of the box.

After listening to Chu Bai's words, Yun'er knew that the comfortable feeling when killing zombies should be caused by absorbing energy.

"!" Chu Bai took the instant noodles, his face was ugly, and he cursed, bad luck, and opened a pack of instant noodles.

"That's what you call the good stuff? I'm really speechless, I just want to eat instant noodles and get them in the supermarket, as for the fee, it's so big. Yun'er was getting bolder and bigger, and seeing Chu Bai's bitter face, she actually made a joke.

Chu Bai ignored her, took out a duck head from his backpack and split it with an axe, and took out the white crystal nucleus inside. Yun'er's eyes lit up, "It turned out that there was something in it, so I said, how can my Prince Charming be so heavy and like to eat duck heads." ”

Chu Bai gritted his teeth and threw the white crystal nucleus into the treasure chest, the white light of the treasure chest was bright, and the hundred energy in the crystal nucleus made the ten grids flash ten times with golden light. A pack of instant noodles is suspended in front of the treasure chest, a total of ten items, and the next one will only appear after taking one.

"Instant noodles and instant noodles are instant noodles" three packs of instant noodles in a row, and Chu Bai was about to go crazy. Suddenly, his eyes lit up, and an object that was clearly different from instant noodles appeared. It was a large bottle of peasant women's spring, Chu Bai just wanted to scold his mother and continue to look forward to the next item. This time it wasn't something to eat, but a black gas stove.

"This broken box is very thoughtful, and there will be fragrant instant noodles to eat!" Yuna was pleasantly surprised, she hadn't eaten hot food for a day. But looking at Chu Bai's bitter gourd face, it was not good to be too happy.

Chu Bai was desperate, and then a delicate silver pistol floated out in front of the box, which made Chu Bai feel a little comforted, but the pistol didn't mean much to him. took the small pistol and handed it directly to Yun'er behind him. Looking at the small silver-white pistol with delicate patterns, Yun'er's eyes were full of stars, she was very happy, and stepped forward to tiptoe and kissed Chu Bai on the face.

"Well, it's not a loss."

Then the box opened out an arm guard and two cans, and there was one last chance left, and Chu Bai was very nervous. A finger-sized glass bottle appeared, containing a green liquid, which was an immunity potion, which could make ordinary people immune to wound infections after zombie scratches and bites.

"If you drink it, you won't have to worry about zombies biting you." Chu Bai asked Yun'er to drink the immunity medicine in one gulp, and personally put the arm guard on her hand. I was very depressed in my heart, and I was busy for a long time, and I was all cheap for this woman.

Chu Bai gave her all the things, Yun'er was embarrassed, looking at Chu Bai's depressed face, she knew that he didn't get what he wanted. She felt uncomfortable in her heart, she wanted to comfort Chu Bai but didn't know what to say, so she could only hug Chu Bai's waist tightly.

"That's right! Don't you still have a duck head? You're so badly lucky, let me try. Yun'er let go of Chu Bai and looked at Chu Bai playfully.

"Okay, let's try it." Chu Bai was very helpless, took out another duck head, took out the crystal nucleus, and was reluctant to hand it to Yun'er. You must know that it is a full hundred energies, how can Chu Bai give it, there are only three in total, he has already used one just now, and now he wants to use another one.

Yun'er saw Chu Bai's appearance as a miser, snatched the crystal nucleus and threw it into the treasure chest, thinking that it was not just a crystal nucleus, as for being so stingy. Seeing her generous appearance, Chu Bai secretly scolded a loser woman in his heart, but he didn't know that a woman was a creature who was not afraid of spending money.

The white light was bright, and the golden light shimmered. Chu Bai and Yun'er stared intently at the treasure chest. A black card gradually appeared, Yun'er was speechless, what did she do, a playing card? Chu Bai was overjoyed, snatched the card, and then smirked.

"What are you laughing at? Show people something. Yun'er looked at Chu Bai smiling like a fool, grabbed the card and pinched it in her hand to look at it. The cards are about the same size as the playing cards, the whole body is pitch black, there is a big number "0" on both sides, and the material is very hard.

"This is an energy card, it can absorb the energy of the zombie when it dies and the energy in the crystal nucleus, and the number above is as much as it sucks. We can use it to collect and pay for energy. Whoever first touches it has been its owner until he dies. Chu Bai thought to himself that Yun'er was getting bigger and smaller, and it seemed that he had to find some time to train well.

"Cut! What's the use of this! I'm still comfortable absorbing my own energy. Why give it energy! ”

Chu Bai looked at Yun'er with Shabi's expression, and she was so angry that her teeth itched. He didn't want to explain, energy cards were a necessity. When zombies die, humans can directly absorb energy, but once zombies evolve, crystal nuclei will be formed, and humans cannot directly absorb energy from crystal nuclei, and must be transferred by energy cards to absorb them.

Once you miss the stage of low-level zombies everywhere at the beginning of the apocalypse, the zombies will evolve into crystal nuclei entrenched in the city in the future, and it will be difficult for ordinary people to evolve directly by hunting zombies, and they can only exchange resources far exceeding a hundred energy from the base for a chance to evolve with energy cards. In Chu Bai's previous life, it was at a great cost that he changed from the base to an energy card evolution.

The energy card is like a credit card in the last days, which can collect energy and pay for energy.

"Wow! Chu Bai, look, there's a knife! Yuna exclaimed in surprise.

"Huh?" Chu Bai got the energy card, and was immersed in great joy and forgot the treasure chest for a while.

A long pitch-black knife floated silently, emitting a cold black light.

Chu Bai trembled and took off the long knife, which was less than one meter long, with a handle twenty centimeters long and a blade of more than three centimeters wide. The blade is pitch black throughout, and the handle grip is a dark red matte material. Although Chu Bai couldn't tell what material the long knife was, it didn't affect him at all to see the sharpness and tenacity of the long knife. At first glance, the crimson handle with the straight jet-black blade makes it look very good, and the bigger is also very tall. Chu Bai held the long knife and shook a few knife flowers, it felt very good, and he couldn't help but sigh: "Appearance is combat effectiveness!" ”

The long knife fascinated Chu Bai, but couldn't charm Yun'er, she was not interested in the knife, at most she felt that the appearance was okay, not ugly. Regardless of the stupid Chu Bai, she always paid attention to the treasure chest, and there were still eight items in the back that did not come out. I didn't expect it to be all instant noodles and mineral water, so isn't there anything else to eat in this box?

There was only one last item left, and Chu Bai also relieved himself from the joy of getting the long knife, looked at the instant noodle mineral water at Yun'er's feet, smiled, and kissed Yun'er. Yun'er was not shy, and kissed Chu Bai instead. Chu Bai was very useful, looking forward to the last item.

A small blue carton floated in front of the two of them, with the English letters "durex" on it, Yun'er blushed, snorted lightly, turned around, Chu Bai smiled and reached out to take the carton and stuffed it into the backpack, staring at Yun'er's back with burning eyes.
