"That's because you haven't come out of the earth and into the universe."

"I don't need to say much about the size of the universe. Countless races exist in the universe. In the whole universe, there are three systems. One is the most primitive cultivation system, which does not attach too much importance to science and technology.

One is the combination of science and technology and cultivation, just like your earth.

And the last one is the science and technology system. In this system, the personal strength may not be very strong, but their intelligence quotient is very terrible. The star warships produced can easily destroy a planet or even a galaxy. "

"In this universe, the size of the planet is divided into five levels, namely, non inflow star, primary star, medium star, advanced star and the most powerful top star.

And the earth, if counted down, can be regarded as an elementary planet. After all, according to my understanding, there are people on your earth who have reached the ability to survive in the universe for a short time.

As for the scientific and technological civilization, they also divided the civilization level into five levels, from the non mainstream civilization to the top civilization.

As far as I know, primary civilization is enough to carry out the universal fulfillment.

Obviously, your earth has not reached this level yet. Naturally, it can only be regarded as close to the primary civilization. "

At this time, Xing Lao also explained to Zhang Fan.

"My God, the earth's current level of science and technology can not even reach the elementary level. How strong is the most advanced civilization and technology?"

Zhang Fan is also a little unimaginable at the moment.

"Ha ha, the strength of the top civilizations is not what you can imagine. It can be said that those civilizations want to destroy the earth, that is, a matter of one second. Sending a star warship at the lowest level can easily destroy the earth directly."

"Although I have lost my memory, according to my calculation, the best one is enough to destroy countless galaxies."

The sails fell silent.

At this moment, he felt his own insignificance, let alone the galaxy, he can not even destroy a mountain.

"Ha ha, you don't have to be discouraged. With the existence of" Xuantian swallowing spirit resolution ", you are likely to become the top-level strong person in the future, and even be able to touch a higher-level secret. Your top priority now is to be able to leave the earth first

Patted the shoulder of a sail, star old smile says.

"By the way, Xing Lao, after you wake up this time, will you continue to sleep after a period of time?"

No longer think about it, Zhang Fan is also looking at the old star in a hurry.

"As long as you don't experience too much consumption, you don't have to sleep. Of course, I can't support your trial space."

Star old words, also let Zhang Fan a sigh of relief, in the heart appears very happy. Then he looked at Mr. Xing:

"that's good. If you are not around, I always feel empty nagging. By the way, Mr. Xing, I found a Patchouli in Gulan college

"Oh? On earth, there is the existence of Bu Tian Zhi? How many years? If it is more than 10000 years old, I can recover some after absorbing it. "

Hearing Zhang Fan mention Bu Tianzhi, Xing Lao is also very surprised.

"Well, only five hundred years."

Zhang Fan sighed and said.

"Ha ha, this has been regarded as a miracle. Bu Tian Zhi, even in the universe, is a powerful elixir. If you can have a plant in Gulan college, it is against the heaven.

However, this kind of elixir can not be forced to ripen, so we can only let it grow slowly, or put it into a special space with time proportion.

Unfortunately, I don't have that strength now. Otherwise, I can change the space of the Star source fragments. If I practice here for one day, it will be enough for the outside world for many days. "

At this time, the old star also showed a pity.
