(Quick knowledge: The new measurement data of the diameter of the Milky Way is 15~200,000 light years.) We are inside the Milky Way, and it's hard to really see how big the Milky Way is. It can only be observed indirectly, or by analogy using the galaxy next door. Different observation methods, means, and calculation methods will have great errors)

The starry sky of the Chengtian Galaxy is beautiful, with a faint haze. That's because of the power of the majestic stars.

Ever since the stars of the Celestial Star were transformed, the power of the majestic stars has permeated the entire galaxy. Years have passed, and the enveloping area of the power of the stars is as wide as 0.6 light-years in diameter.

When a large amount of star power reaches this location, it will stop advancing.

The power of the stars, aura, etc., cannot be moved by itself. They rush out of the star with the solar wind, etc. And when the solar wind stops moving forward due to the gravitational pull of the stars, the aura naturally stops moving forward.

Here, because the solar wind stops advancing, a large number of particles, aura, etc. are piled up here.

At a distance of about 0.3 light-years from the star, a relatively conspicuous, invisible shell that can be detected by instruments appears - this shell is called the stellar shell.

The stellar shell is also the limit range of the star's magnetic field. Behind the shell, behind the direction of the star's rotation, a tail two light-years long is dragged.

Transforming a star is really not comparable to transforming a planet. The aura layer of Tian Yuan Star is only more than 200 kilometers high, and the density of aura can only meet the needs of cultivation at about 60 kilometers.

The aura range of the Chengtian Galaxy is as wide as 0.6 light years, and the density of the aura meets the needs of cultivation, with a radius of as many as 5.7 billion kilometers - this radius is the average orbital radius of the outermost planet of the Chengtian Star System, the Iron Throne Star.

Because of its relatively large size and gravitational pull, the Iron Constellation Star has attracted a lot of aura to converge on the surface of the planet. Therefore, the density of aura on the surface of the Iron Throne planet is very impressive. Coupled with technologies such as the Spirit Gathering Array, Dayang Group has created a cold medicine field here.

What is grown here is some super low-temperature medicinal herbs and even living organisms. Most of these ultra-low temperature life forms are small and grow extremely slowly, and many of them are provided by the Sufeng Clan.

And the entire Chengtian galaxy has almost been transformed into an interstellar medicine field. Some space plants obtained from the Su Feng Clan, as well as some plants transformed by Zhou Xueyao, grew healthily in the starry sky.

In the rich aura environment, let them grow wildly. To take care of these plants, it is enough to provide the necessary minerals, water, etc. Some plants are directly entangled in the comet and rely on the comet's nutrients to grow.

In just a few years, the Chengtian Galaxy has produced the first batch of medicinal materials here. Just a month ago, the Chengtian Galaxy produced a full 2 million tons of pills below the Yuan Infant level!

And today, the 2 million tons of elixir have finally been packed, and a huge fleet has set off.

At this time, there were still negotiations on Tianyuan Star, and the people in charge of negotiations in the Ocean Group did not know what was happening here in Chengtian Star.

Zhang Hao took the senior management of the Dayang Group and watched the fleet go away.

The new technology allows the acceleration of the battleship to reach 1,000 meters per second, which is almost three times the technology of the Red River civilization!

The science and technology of Dayang Group are bearing brilliant fruits one after another.

However, because there is a lot of aura here, the acceleration of the battleship is still affected a little. Finally, after a day and a half, the battleship reached the speed required for time travel, and then the battleship ...... Suddenly disappeared from the starry sky, without a trace!

Combined with the teleportation technology, as well as some of the technologies of the Sufeng Clan, the Ocean Group has developed a real, warship teleportation technology. This teleportation is not fast, and theoretically only one-third the speed of light. But the most important thing is stealth!

The dispatch of the fleet by the Ocean Group this time is top secret.

Chengtian Star is the rear of the Ocean Group, and the entire starry sky is shrouded in aura, and a little arrangement can form a hidden enchantment. And before the fleet left the aura layer, it entered the chrono travel, and there was no trace at all.

At this point, the first real interstellar commercial exchange of Dayang Group has officially begun. And in this exchange, Dayang Group finally made up its mind and completely put aside those pig teammates who were dragging their feet.

This time, the person in charge of the fleet is Dugu Junjie. Compared with other captains, Dugu Junjie's military ability, communication ability, adaptability, etc., are all superior. The commander's ability is not as good as Murong Shan's, but this time he doesn't need the commander's ability. Moreover, Murong Mountain is an important pillar of the Dayang Group and cannot be left easily.

Watching the fleet leave, Zhang Hao couldn't help but sigh in a low voice: The United Nations ...... Hmph, rotten wood can't be carved, and the wall of dung can't be smashed!

After sending off the fleet, Zhang Hao finally had the mood and time to wander around. It's been a long time since I've been to Chengtianxing, and Zhang Hao can't help but want to visit.

At this time, the celestial star system, because of the accumulation of a large number of aura of the power of the stars, faint and ethereal, a layer of light blue 'gauze' appeared on the surface of the entire star, and the solar wind continued to lift a corner of the sarra, and the gauze would rush into the starry sky with the solar wind.

Maybe the so-called Wizard of the Clouds is nothing more than that.

The surfaces of the three planets closest to the stars have condensed a large amount of aura through gravity. At this time, the three planets were almost in the same line, and Zhang Hao saw the hazy beauty of the three planets at a glance with the powerful eyes of the cultivators.

Beyond the atmosphere, there is also a circle of aura. The entire planet is enveloped in a rich aura.

In the starry sky, from time to time, there are oversized 'greenhouses' floating by, which are planted with a large number of relatively delicate space medicinal materials.

There are also many vines and miscellaneous bushes, etc., which are rooted in comets and drifting in space. These tough, true space plants, which can draw nutrients from comets, can directly receive stellar glow that is not filtered by magnetic fields.

Suddenly, an asteroid with a diameter of about 100 kilometers quickly floated in the distance. The orbit of this asteroid crosses somewhat with that of the second planet. However, the technical staff of Dayang Group are also constantly supervising and fine-tuning to ensure safety.

This asteroid has an irregular ellipse, and the surface of the asteroid is no longer visible in its original color. A large number of vines, shrubs, lichens and other types of vegetation grow on the surface.

One of the vines took root on the planet, and its vines floated in the starry sky, dragging thousands of miles in length and parting endlessly. It is a gourd-like plant with leaves up to 100 meters in size and a series of large and small gourds on the vines. In some places, you can hang a dozen gourds in one go, clustered like cherries.

These gourds are large and small, small three or five meters, large tens of meters, hundreds of meters. A little bit of spiritual light flickered on the surface of the gourd.

"Is this the starry gourd you cultivated recently?" Zhang Hao asked Zhou Xueyao next to him.

"This is the fairy gourd!" Zhou Xueyao glared at Zhang Hao angrily, "I only told you the name for the twelfth time yesterday!"

"Oh...... This space hoist is good. It's about to be harvested, how much can be harvested in the first batch...... Ahh......h
