The voice of the weapon spirit sounded, and the test was passed. Gu Zheng knew it without the tool spirit reminding him, but what is the true meaning of this cooking part?

Is there still part of the truth?

"The reward, the prehistoric space has been doubled, has been distributed!"

The expansion of prehistoric space doubles each time, but this doubling is not doubling the area, but the distance.

The prehistoric space is almost square. Each time it is doubled, it is equivalent to a four-fold expansion of the area. For example, the original area is one meter times one meter. After the expansion, one meter becomes two meters, which is the range of two meters times two meters.

.

In fact, the ancient space in Guzheng is already quite large. It was only a few dozen square meters in the beginning. After two expansions, it has grown to nearly a thousand square meters. In addition to things for planting and breeding, many things can be put there.

.

After taking out most of the Kongkongmen treasures obtained last time, the place became even emptier. Gu Zheng was still thinking about whether to build a small house in it if the prehistoric space expanded again in the future, although he only spent a short time there every day.

, but there is a small house where you can also have a good rest.

The spiritual power in the ancient space is very abundant. Even sleeping here can increase a lot of spiritual power.

"Reward, fifty ordinary immortal pills!"

The voice of the weapon spirit sounded again, and Gu Zheng was stunned for a moment. Fifty pills. This time the weapon spirit was very generous. He actually rewarded fifty immortal essence pills. Although it was not a medium level, it was not bad.

Today's Gu Zheng is not at the beginning when he didn't understand anything. He is very clear about the value of Xianyuan Dan. It is enough for him to take it all the time to increase his immortal power. This is something that other elixirs cannot do.

"Reward, ten space stones!"

The weapon spirit told the reward again. The space stone is a kind of material that can be used to repair the chaos tower. This time the weapon spirit released another one.

The rewards are good and generous, and Gu Zheng is also very satisfied.

After receiving the reward and completing the test, Gu Zheng finally felt relieved. He no longer had to worry about the prehistoric space being taken back. After getting used to the various conveniences of the prehistoric space, Gu Zheng was really afraid of losing it.

All the rewards were given to Gu Zheng, which made Gu Zheng feel very good. This test was completed ahead of schedule, with one day left...
