Traveling through the doomsday, I become the largest supplier

In the small rental house rented by Zhou Feng in modern times, the space was slightly distorted, and the dusty Zhou Feng appeared in the room. Looking at everything familiar, Zhou Feng couldn't help but confirm that this was not a dream, until he heard the roar of cars peculiar to the city, he was sure that all this was a real journey to the end of the world.

Just like the first time, Zhou Feng couldn't help laughing, ignoring the mud and dust on his body, he threw himself directly onto the bed and screamed and roared. He dragged the chest from under the bed containing the gold from the first sale, opened it and poured it all over the bed, illuminating the room with a golden glow. Then, he threw the gold and crystals obtained from the second transaction on the bed from the space library, and the more he looked at it, the more excited he became, and even picked up the Type 95 and waved it. The way he is now, if someone breaks in and sees it, they will definitely think that he is a robber.

Compared to the dazzling gold, a dozen white and a few blue crystals are much softer. After being excited, Zhou Feng suddenly remembered that these crystals were dug out of the zombie's head, and he immediately felt disgusted, so he took the crystals from the bed and threw them on the small dining table next to the bed.

It was only now that Zhou Feng had time to study what happened today. Judging from the changes in the space-time ring, it must be related to these crystals, otherwise it would not have changed from a level 0 unactivated state to a level 1 activated state after the crystals were discovered.

Zhou Feng wanted to figure out a few functions of the Space-Time Ring's Level 1 state, so he focused his attention on the gray experience bar. He discovered that the Spacetime Ring could be upgraded, but he didn't know how, as he traded twice and crossed twice, but the experience bar didn't change at all.

Zhou Feng suspected that the upgrade was related to the crystal, so he endured his nausea and picked up a blue crystal to observe carefully. The crystals are oval-shaped, resembling sapphire, and very hard. Under the sun, there seems to be a blue liquid flowing inside the crystal, and it seems to contain some kind of energy.

"This is an unknown gem at all!" Zhou Feng thought to himself. For the sake of safety, he did not dare to bring the crystals back to modern times, and decided to make a fortune through gold and other items. Zhou Feng studied for a while, but still had no clue. He put the crystals into the storage space, there was no reaction, and then thought "use the crystals" with his mind.

Sure enough, as Zhou Feng thought, the space-time ring reacted to his thoughts. An information panel appeared in his mind, displaying the "Use Level 1 White Crystal, Confirm/Cancel" select button. In order to verify the correctness, Zhou Feng hesitated, but still chose to confirm with his mind. With his confirmation, the white crystal in his hand disappeared out of thin air, and in the original gray experience bar, the experience point increased by 0.1%, indicating that it was still 99.9% away from leveling.

Zhou Feng swallowed his saliva and said, "I didn't expect that the upgrade of this ring really depends on the crystallization in the zombie's head. He suddenly thought of something, sighed, and fell heavily on the bed with his head up to the sky, "Paralyzed, this ...... It's all money!"

After figuring out the mystery of the ring upgrade, Zhou Feng was in a good mood. He used another white crystal, and the experience bar showed that it had 99.8% left. After several experiments, Zhou Feng finally determined that 1 white crystal could increase the experience value of the space-time ring by 0.1%. To reach level 2, you need 1,000 white crystals, which is 1,000 zombies.

"Fortunately, 1,000 white crystals are not difficult to get, and you can upgrade them as long as you resell them ten or so times. Zhou Feng thought for a while, took out another blue crystal, and chose to use it. The experience bar immediately increased by 1%, leaving 98.8% to level up. It is clear that blue crystals are 10 times more powerful than white crystals. Since there were no crystals above green, Zhou Feng did not know that the green crystals were several times that of the blue crystals.

100 blue crystals can be upgraded, which is still very easy for now. But Zhou Feng is not optimistic, the first level will need 100 blue crystals, what about the second level? How much will it take? There will definitely be a third and fourth level, or even more. In this way, the crystallization required is undoubtedly astronomical.

Now Zhou Feng understands that the space-time ring is not a tool for people to make money, but a tool for people to help it upgrade. After studying the problem of the experience bar, what puzzled Zhou Feng the most was the first-level DNA enhancement function. So far, the Temporal Ring has only provided two accessory features: time-traveling and storage. The end times are full of threats from zombies and humans, and they may die at any time, doesn't this ring worry about their own safety? Maybe the first-level DNA enhancement refers to enhancing the genetic ability to make oneself stronger. The idea is crazy, but well understood.

Zhou Feng licked his lips and decided to test whether this function was really as he had guessed. If it is true, then he is no longer a weak person and can escape the fate of being bullied. Zhou Feng was the target of bullying when he was in elementary school, although he did not leave a psychological shadow, but he was very unhappy in his heart. This happens to me once in a while after work. Even when he had a girlfriend, he was secretly ridiculed as frail and sickly. These past events flashed through Zhou Feng's mind, and he took a deep breath and said, "Activate the first-level DNA enhancement!"

After Zhou Feng issued a mental command, the first-level DNA enhancement in the space-time ring was not activated and became active. Zhou Feng immediately felt his blood boiling, every cell in his body felt as if he had been pricked by a needle, and the soreness instantly spread throughout his body. This soreness was fleeting, but Zhou Feng could clearly feel that his body was full of powerful strength. He jumped up in the rental house with excitement.

In order to test his strength, Zhou Feng took out an iron rod and folded it with both hands, and the two-finger-wide iron rod was bent under the huge force, and then twisted into a twist by him. After many tests, Zhou Feng determined that his strength, physical strength, senses, and reflexes had all increased by a factor of three.

"The first-level DNA enhancement can increase one's ability by three times, so how many times will the second-level DNA enhancement increase?" Zhou Feng hadn't tried it and couldn't know, but he was sure that with the upgrade of the space-time ring, his ability would become stronger and stronger. At present, three times the strength is slightly stronger than a strong man, which is enough for the thin Zhou Feng. But he is not satisfied, the danger of the last days is too strong, although he can fight one against two, but he can't fight ten with one, one against hundred, and his life is still very fragile in front of guns.

"We must speed up the transaction volume and increase the level of the space-time ring as soon as possible, so that we can have the capital to save our lives. Zhou Feng understood the cruelty of the end times, and he was not carried away by the effects brought by the first-level DNA enhancement. Although wealth such as gold is very tempting, he knows that he can only enjoy wealth if he is alive, so until he has enough strength, it is his development strategy to keep the necessary low profile.
