A group of air fighters flew directly towards the Yundian Fortress. They wanted to take advantage of the fact that the main force of the sky fleet was still in the City of Sin to launch a sneak attack on the fortress and let the Rune Kingdom taste the feeling of being attacked. However, what they didn't know was that after Jiang Feng's comprehensive transformation, the defense of the Yundian Fortress was no joke.
After the large-scale defense system was activated, the solid defense barrier directly covered the entire mountain. The powerful missiles and various artillery shells from the fighter jets bombarded it and exploded like fireworks. The rebound force field behind the defense barrier directly bounced away all the explosive impacts. The entire fortress can be said to be as immovable as a mountain.
The fierce bombardment of fighter planes could not do anything about the powerful defense of the fortress, but the laser cannons and photon cannons inside the fortress in the defense barrier could shoot at these fighter planes without any hindrance.
After losing several fighters and failing to achieve any results, the remaining fighters had no choice but to retreat. However, the pilots did not notice that there were tiny reconnaissance eyes in the sky above them that were tracking their return route.
These reconnaissance eyes were covered with interference runes and could not be detected by ordinary detection. After these fighters returned to the base, Jiang Feng controlled the sky aircraft carrier and brought the sky fleet to the sky above this extremely hidden base at night.
After that, a battle broke out without any suspense. After a large number of jamming bombs were dropped, precision strikes began. A large number of fighter jets parked below were destroyed, and all defensive weapons were blown into scrap metal. After the defense system of this base was completely broken, one rune mecha after another began to come on the scene to clean up the personnel inside. The entire base was controlled by the combat team in a very short time.
Although there are several executioners responsible for defense here, their strength is just so-so for Jiang Feng now. Facing the attack from more than a dozen rune mechas, the only way out is death.
Finally, Jiang Feng began to collect internal information about the Huanglong Group. All useful materials were moved away, and after the fleet left, the entire base was completely destroyed by the reserved bombs.
All this was completed in a very short time. It was not until dawn that the top management of the Huanglong Group discovered that something had happened to the base. When they sent people to check, they saw only a huge ruin. There was no living person at all, and all the useful things inside had been moved out.
After this lesson, the Huanglong Group never chose to act rashly again. They secretly began to send a large number of executioners to collect information about the Rune Kingdom, and at the same time communicated with other forces to prepare to give the Rune Kingdom a fatal blow when the opportunity came.
Jiang Feng certainly didn't know about these, but he could still guess that Huanglong Group wanted to take revenge on them. Could he still expect them to be grateful after suffering two losses in a row?
So he quickened his pace without hesitation. The number of people in that sinful gathering place was constantly decreasing. The entire Yundian Fortress had maintained a population of about 10,000. New people came in every day, and people were also sent to the South American base every day.
After this battle, some large forces recognized Jiang Feng's strength and finally agreed to his request. Various materials began to gather from various forces to the Yundian Fortress, and then were transported back to the South American base, and finally turned into powerful sky battleships returning to the Yundian Fortress.
Their strength grew rapidly like a snowball. The number of sky battleships gradually reached hundreds, and the total number of personnel in various bases increased to 120,000!
A large number of people who were willing to become combat team members began training in the rear. The reserve forces and trained psychics left by Jiang Feng also became formal team members. Now the number of combat team members has exceeded a thousand!
Moreover, the rune mechas have been rushed into production and the number has reached 300. Coupled with the growing number of metal termites, their power on the ground has become extremely powerful.
A month later, all the survivors were completely absorbed by them, and the population of Yundian Fortress remained at a constant of 5,000.
