Find the complete story of the halo

In the distant future ... mankind has established a huge interstellar empire, and the United Nations Security Council with the earth as the core rules the whole human society. Immigrants have traveled all over the solar system and some nearby galaxies. On the way of interstellar migration, human beings fought against the alien interstellar alliance from Orion galaxy.

Humans know very little about the interstellar alliance, except that it is an alliance of six or seven races (or even more) who believe in the same religion. They followed their mysterious religious beliefs and firmly believed that the pace of human exploration trampled on this belief, so they vowed to destroy mankind.

In 2552 AD, the war between human beings and the Star Alliance reached a white-hot stage, and human beings with relatively backward technology have been at a disadvantage in the war. That year, Qu Rui, an important colonial planet of mankind, fell under the sudden attack of the Star Alliance. In the battle, a destroyer named "Autumn Wind Wharf" successfully escaped from danger. According to the Cole Agreement, all ships must ensure that the Star Alliance can't find the earth. The "Autumn Wind Pier" came to a mysterious artificial ring "halo" through "blind jump". This halo is 10000 km in diameter, with mountains, water and plants ... the same climate change as the earth.

The second raid of the Star Alliance fleet made the autumn wind wharf unable to resist. Captain Keith decisively ordered everyone to evacuate to Halo, and the only Spartan John (known as the "Chief Sergeant") on Qiufeng Wharf came to Halo with the artificial intelligence of Qiufeng Wharf.

Because of the different landing sites, the sergeant needs to find the remaining human forces and rescue Captain Case who has been captured by the Alliance.

After several encounters, the sergeant successfully rescued Captain Keith and discovered the mysterious use of the halo-the pioneer made it and used it to trap the heterogeneous zerg, a kind of tenacious parasitic alien. Even wise pioneers are afraid of the existence of this alien.

At this time, Captain Keith, who went to the rainforest to find the enemy's arsenal, disappeared again. The sergeant led a small group of people to rescue him, but he was caught in a triangle melee with the Star Alliance and the Zerg. In times of crisis, the evil spark of Halo's artificial intelligence 343 appeared in front of the sergeant, claiming that he could find a way to destroy the Zerg. Under his command, the sergeant went all the way to the library indexer at the core of the control room and opened the aura.

Unexpectedly, the so-called elimination of the Zerg by 343 Evil Spark turned out to be the elimination of the parasitic body of the Zerg-all living things in the galaxy. The sergeant had to break through the encirclement and destroy the three pulse transmitters necessary to start the halo. In order to prevent the evil spark of 343 from starting the halo in other ways, the sergeant found Captain Case, who had been parasitic by the Zerg, under the guidance of Kotana, and got the chip from Captain Case to detonate the Qiufeng Wharf nuclear power plant. After destroying the dissolution reaction device at Qiufeng Wharf, a powerful nuclear explosion destroyed everything in the halo. Sergeant and Cotana escaped from the halo in a long sword interceptor. ...
