After receiving a large order, Tang Zhen was naturally very happy. After taking the time to pass it home, he found the phone number of a slingshot seller on the Internet and ordered 10,000 ordinary cold-formed slingshots.

This kind of ordinary slingshot is easy to process, because Tang Zhen doesn't have too many requirements for the material, so he only needs to use ordinary round steel with a simple workbench to make it.

Then it is polished and polished, and the slingshot is completed.

The price of ordinary slingshots is cheap, 10,000 pieces are less than 100,000 yuan, and then Tang Zhen ordered a large number of rubber bands and steel balls, and requested that they be shipped as soon as possible.

After finishing all this, Tang Zhen returned to the Loucheng World.

The slingshots he brought were sold out, and many people came to ask if they were in stock. What Tang Zhen didn't know was that when he left, another wave of death birds struck.However, because there were hundreds of slingshots in the town of Wanderers, the thousands of dead birds that had struck were quickly killed.

Contrary to Tang Zhen's expectation, the special agent of Black Rock City who was staying in the town of Wanderers also found him on his head and wanted to order 5,000 slingshots from him, as well as a large number of steel balls.

What Tang Zhen didn't know was that at this time, Black Rock City had been besieged by nearly 100,000 dead birds. These monsters were flying around Black Rock City endlessly like a huge black cloud.

In order to prevent death birds from entering Black Rock City, all doors and windows have been closed, but even so, many residents are still injured.

If you are injured by this strange bird, you will definitely die. For this reason, the ruler of Black Rock City had to throw these residents who became zombies out to prevent the entire building from collapsing from the inside.

The appearance of the slingshot made the Black Rock City commissioner see the hope of relieving the death bird crisis. For this reason, he specifically found Tang Zhen and asked him to provide goods as soon as possible.

The Black Rock City Commissioner even promised that if the crisis in Black Rock City can be resolved, Black Rock City will never forget his credit and even give him the qualifications of a reserve resident!

Tang Zhen didn't care about the resident status of Black Rock City, but he had to care about a business worth tens of thousands of brains.

The commissioner of Black Rock City was very refreshed, and directly paid ten third-level brains, which was equivalent to 1,000 first-level brains.

Tang Zhen estimated the time and promised to deliver the goods in three days. Although the other party was a bit dissatisfied, he couldn't help it. After all, he ordered too many quantities, and it is normal for Tang Zhen to delay delivery for a few days.

After sending away the special commissioner from Black Rock City, Tang Zhen was able to cleanse for a while.

This time the big sales of slingshots were a bit beyond his expectation. After counting the total sales, it actually exceeded 15,000 brains.These brain beads are equal to 150,000 gold coins in the app mall, which is not a small income for Tang Zhen!

But this time, he was not eager to absorb the brain beads, but put it in the storage space for emergency needs.

While thinking about the matter in his heart, Murong Ziyan walked into the cave. He looked at Tang Zhen and smiled, and then asked in a caring tone, "The matter has been resolved, right?"

"Relax, it's okay!"

Tang Zhen smiled indifferently, indicating that he was fine.

Murong Ziyan nodded, stepped forward to hold Tang Zhen's arm, and nestled her head in his arms and said, "You have to be more careful when you encounter such a thing in the future. The last time you were injured, I was terrified."

Tang Zhen nodded, patted Murong Ziyan on the shoulder and said, "I know, I will pay attention to it in the future. Go and cook. I'm a little hungry."

Murong Ziyan nodded obediently, turned and walked out of the cave, Tang Zhen's expression looked very relaxed.

After a short while, Qianlong came back. As soon as he saw Tang Zhen, he punched him on the shoulder and asked with concern: "I think that guy hasn't come back these days. I think it has been solved by you. No, I'm not hurt, right?"

Tang Zhen nodded, and said with lingering fear: "The process was a bit thrilling, and I was almost overwhelmed by that bastard, but fortunately, that guy has been killed by me, and his gang can't come back."

Qianlong nodded: "Since you have killed your beard, the team behind him will definitely not let it go easily. We must be careful during this period. By the way, are there anyone nearby when you do it? If we...?"

When talking about this, Qianlong made a pose of cutting his throat.

Tang Zhen shook his head and said, "Don't worry, no one should see it. Even if someone hears the sound, they shouldn't see my face. It should be fine."

The topic ended, and the two chatted about the dead bird again.

Black Rock City.

Countless death birds are like a huge black torrent, circling around the entire building city, and at the same time they are looking for a gap into the building city.All the windows were blocked, and the archers shot one arrow after another from the narrow hole specially left.

It's just that this kind of attack is not worth mentioning for the huge number of death birds. Moreover, the number of arrows in Black Rock City is limited, and it is almost consumed at present.

The entire Black Rock City fell into a panic and confused mood. Although the residents were still working, they always seemed absent-minded. In the homes of those who died, a low sob could be heard from time to time.

Xiao Rui left home as usual, and his sister went to work. Because of being besieged by the death bird, her work place was temporarily changed to a bow and arrow manufacturing workshop, and arrows were produced day and night.

It’s just that I heard from my sister that the raw materials such as arrow shaft feather glue are almost consumed, I am afraid that in one day of production, the entire Black Rock City will not be able to produce another arrow.

The death birds seem to be endless. Their calls make people sleepless at night, and even Xiao Rui is not able to sleep well. From time to time, a few birds hit the window and make a "boom" crash.

Yesterday the teacher informed them that today they will go to the top floor of the city to replace the exhausted Black Rock City monk and shoot the dead bird.

There are thousands of students in their school, and the minors under the age of 18 in the entire Black Rock City are concentrated, but for the consideration of cultivation, all the students who participated in the defensive battle this time were students with a cultivation level of two or higher.

After arriving at the school, after the call-up, everyone climbed up the stairs together and crossed the iron gate that they were forbidden to pass through on weekdays.

After climbing for a while, when passing a floor, Xiao Rui vaguely heard that the guy who bullied himself was bragging to his companions, saying that there was a treasure house at the end of this floor. He once heard grandpa say that the entire Black Rock City Your baby is hidden here!

Xiao Rui's heart jumped when he heard this and secretly wrote down the information.

At the same time, a mysterious person who can be invisible suddenly appeared in his heart. It was this guy who gave him a thousand brains and used it to purchase a lot of auxiliary materials. Today's cultivation base has touched the threshold of level three!

If you don't know this important piece of information, how many brains will you get from that guy?
