Distance: 1700 light-years outside the solar system;

Time: 67 million years ago.

Three million years have passed, and the planet is prosperous again, with lush greenery and a richer variety of animals, in addition to those giant animals and birds, there are also some smaller animals.

The tenacious and great Red Iron Divine Tree once again sheltered and nurtured the human seed of the Prince Star, and although most of the human buildings were destroyed in that natural disaster, the Red Iron Divine Tree, the altar, and the bronze statue of Futie on Shitie Mountain survived.

The appearance of the Iron Guards has not changed much, except that they look closer to humans, their eyes are no longer so abrupt, their ears are no longer so high and pointed, and the signs of feathers between the ribs have completely disappeared.

Compared to before, the speed of evolution of the Taizi Star civilization has accelerated significantly, and it only took 3 million years for them to evolve to the gunpowder age.

From the original musket bird gun, step by step to the later projectile cannon.

The range of the cannon on Prince is not too far, because Prince is a metal planet, and the gravity of 3G, just like restricting the movement of animals, also limits the range of projectiles.

The Futie people believed that all of this was a gift from the Red Iron Sacred Tree, and they became more devout in their worship of the Sacred Tree.

As for the earliest four-feather sword, it has long been missing, only the four-feather heavenly sword cast later is still in the hand of the bronze statue of Futie; They believe that this is the power of their protector, the god of the dark starry night.

There was still war between the Futetsu people, and at one point there were several large-scale clashes between several tribes, with both sides using giant artillery.

Thousands of cannons were fired in formation, and each artillery battle caused hundreds of thousands of casualties, both samurai and innocent civilians.

Later, the people who died under the artillery fire were more than a million, and later, the Futie people woke up and decided to stop the artillery battle and reduce unnecessary deaths of people on both sides.

They thought that since they were all descendants of the Red Iron God Tree, it was not suitable for them to fight against each other anymore, so they reverted to the ancient aristocratic method and replaced bloody battles with competitions.

In each dispute, the two sides pull out their cannons and play a game, with an arbitration committee setting the rules and schedule for the final decision.

Sometimes the power of the game is to set up a patch of grass targets in the target area, and compete to see who has the most targets to knock down.

Sometimes the accuracy of the game is to set a fixed target in the target area to see who can hit more accurately.

After the dispute was resolved, everyone went to the altar collectively to worship the Red Iron God Tree and the Futie God Statue to express their gratitude and protection to the gods.

In a harmonious atmosphere, the Taizi Star civilization is developing rapidly.

The last time they escaped from the black hole, both Prince Star and Stellar Hem were hit hard.

Prince Star was exposed to intense radiation from the black hole, which damaged the Earth's core, causing a decrease in the core's ability to store energy.

As for Hem Star, its structure has been damaged due to the strong pulling, and its ability to emit light and heat has also been greatly affected.

At this time, the solar radiation heat of Hem Star alone cannot reach the energy balance of Prince Star itself, and every once in a while, Prince Star needs to replenish energy, otherwise it will endanger the internal operation of the planet.

Energy replenishment is generally carried out at the time of the solar eclipse of the star star.

At this time, Hem Star will form a gravitational field behind Butani, which will help Butany gather energy and inject it into the core of Prince Prince in the form of radiation.

The last energy replenishment was carried out when the Iron Man forged the Four Feathers Heavenly Sword, and now the Prince Star needs to replenish it for the second time.

The lessons of the Bronze Age extinction forced Butani to be more cautious and adopt new tactics this time.

Butany has carefully chosen the place of infusion: a barren and inhabited mountainous area on Prince Prince.

He also moved away from using extremely high-energy gamma rays, instead using relatively mild X-rays, although this would take longer to complete.

This partial solar eclipse lasted for a whole month, and the Futie people on Prince Star left everything behind, lit a bonfire, lit torches, and knelt down at the foot of Shitie Mountain intently, praying, worshipping, and guarding for a whole month.

The continuous darkness has finally passed, and the energy replenishment of Prince Star is complete.

There were no volcanoes, no earthquakes, no tsunamis; Except for a month of dark nights, everything was fine.

The sun regained its light, and Prince was once again full of energy.

At the foot of the mountain, the iron men sang and danced merrily, day and night, until their shoes were torn and the ground was crushed.

In order to express their admiration for the sacred tree and the statues of the gods, the Futieren cast more unrestrained and exquisite bronze ritual vessels.

Some of the ritual vessels, still divided into two rows, are placed at the foot of the hill in front of the altar.

Most of the ritual vessels, along with some animal sacrifices, were buried around Shitieshan after a grand sacrificial ritual for the gods to enjoy in the other world.
