It is still the new iron castle city, in the core of the city, in a huge oval building.


    Optimus Prime stood quietly on a metal platform more than ten meters away, which was like a huge bed. At this time, his teacher, the former leader of the Autobot camp and the former king of premes - the natural enemy.


    A special protective glass completely isolates the metal table.


    Optimus Prime''s adjutant, the ambulance, the most famous medical officer in the Autobot camp, is busy in front of the metal platform.


    The ambulance is maintaining the body of the natural enemy!


    Who knows what happened to the former king of premes in more than 100 years after his disappearance.


    His body was badly damaged, and all kinds of wounds made him look almost like death.


    To make matters worse, the natural enemy also got the most feared disease of Cybertron - Cosmic rust.


    This is an extremely terrible disease for Cybertron people.


    Like all kinds of terrorist infectious diseases on earth, cosmic rust is also caused by a magical subminiature virus. Scientists on Cybertron named that subminiature virus [rust source bacteria].


    [rust source bacteria] can survive in extremely harsh environments. For example, the oldest [rust source bacteria] found on Cybertron has been proved to come from the universe.


    They fell to Cybertron with a meteorite and eventually led to the terrible catastrophe that almost wiped out the Autobots and Decepticons.


    That''s why cosmic rust is named!


    [rust source bacteria] they feed on a special substance in the metal. The metal eaten by them will produce a very violent oxidation reaction, resulting in serious rust.


    The reason why Cybertron civilization has not been eliminated by cosmic rust is also due to the special body of Cybertron people.


    [rust source bacteria] feed on a special molecule in metal. Cybertron scientists found that almost all metal elements they know, including artificial alloys, become very vulnerable to [rust source bacteria].


    However, scientists in Cybertron also found that [rust source bacteria] were not interested in pure energy bodies, and even showed extremely strong rejection.


    Although most of Cybertron''s body is composed of metal, the core fire is an energy body very different from cognition.


    It was the energy spilled from the fire that maintained the body function that Decepticons and Autobots struggled to resist the cosmic rust.


    Rao is so, Decepticons and Autobots still paid an extremely painful price.


    The first civil war on Cybertron would end hastily, which was the result of the invasion of cosmic rust.


    It can be imagined that in the face of this extremely difficult disease, the pressure of the ambulance is much greater.


    In fact, since the Autobots found the natural enemy on the moon and brought him back to earth in the crashed spacecraft a few days ago, the ambulance has been checking and dealing with the dying natural enemy.


    He is one of the few Autobots who have known that the energy in Optimus Prime''s [leadership module] is on the verge of depletion.


    Therefore, some injuries that can be solved by surgery and save the consumption of [leadership module] as much as possible will be completed by the ambulance as much as possible.


    The purpose is only to save more lives when necessary.


    The rescue work that lasted for several days came to an end with the ambulance''s hands gradually returning to their original appearance.


    In front of the special glass isolation door, the ambulance walked out of the blue special energy door and looked at Optimus Prime and nodded slightly.


    "Leader, your Majesty''s body maintenance has come to an end. I have dealt with most of his injuries, and the rust has been controlled within a certain range. I will be ready to replenish energy for his fire. I believe that with your Majesty''s strength, you can fully recover in a month or two!"


    Optimus Prime frowned slightly and asked, "it takes so long? I''d better wake up the teacher directly with [leadership module]."


    The ambulance quickly advised him, "leader, after the war on the back of the moon, the energy in the [leadership module] has become less and less. You''d better leave it to treat more companions when needed!"


    Tin met with him and cross cannon privately not long ago. The topic was about Optimus Prime and natural enemies.


    Ambulances are old qualified Autobots like tin.


    However, unlike Tin''s disdain for Optimus Prime at the beginning, he recognized this gentle and modest young leader long ago.


    When the horizontal cannon defected from the Decepticon army to the Autobot camp, if Optimus Prime pleaded, the natural enemy who hated the Decepticon would kill the bold soldier on the spot.


    Therefore, after a little contact, the three Optimus Prime aides and confidants reached a consensus.


    In order to maintain Optimus Prime''s leadership position and have many doubts about the easy return of the natural enemy, the three Autobots agreed that the awakening time of the natural enemy should be appropriately delayed in order to squeeze out more time to investigate whether there is a Decepticon conspiracy behind it.


    Now, based on this consensus, the ambulance is trying to prevent Optimus Prime from using the [leadership module] to directly wake up the natural enemy.


    Optimus Prime hesitated a little when he heard the speech. The energy in the [leadership module] is indeed on the verge of depletion. It''s not that Optimus Prime hasn''t thought of a solution.


    Jack, his chief scientist, is currently analyzing the essence of the energy in the [leadership module] and studying what means to supplement the special energy in the [leadership module].


    At present, the jack has achieved certain results. According to his test, the [leadership module] can indeed absorb external energy to supplement itself, but perhaps the energy in the [leadership module] is too advanced. Even the high-purity energy solution purified by the Autobots has little supplementary effect on the [leadership module].


    [leadership module] has the ability to awaken death fighters. This alone is enough to demonstrate its value.


    This is also the reason why Optimus Prime will hesitate, because he already wants to revive the dead Autobots, and the routine operation of the ambulance cannot be done.


    Seeing the hesitation on his face, the ambulance approached and advised again: "leader, there are too many suspicious things about why his Majesty''s ship crashed on the moon, why the Decepticons didn''t take or kill him, and why they suddenly stopped pursuing at that time."


    "Both tin and I doubt that Decepticons are plotting. So I suggest you be more cautious."


    "New iron castle city, but our last home!"


    As soon as he said this, Optimus Prime couldn''t help recalling all the suspicious things he had encountered on the back of the moon.


    He took a deep look at the natural enemies lying on the metal Taiwanese businessmen, thought for a moment, and then nodded slowly.


    "I see!"
