Ranju leads a simple charge, Big mom forced had around 400 pirates in it many of who didn't have DF. With his 1100 men, the battle was easily won. With No casualties, Ranju division returned. Leo seeing the situation under control. Leo went back to his division. Reports of both the forces which went to capture Blackbeard and Impel down came in with both teams completing their missions.
Luffy who was at Impel down was already informed about the situation by one of Leo's subordinated decided to come with them. Meanwhile, the rest of the world went into chaos. With most of the Marine forces gone everyone wanted to take advantage, Arcnologia who was assigned under the five elder was given command over the marine forced by the elders who then at first decided to regroup the rest of the forces at Mary Geoise under the pretext of protecting the Celestial dragon as priority which was approved by the Elders who also ordered all the CP units to report in. Leo got the report of everything via Hope which overlooked all situations. Leo orders all his forces to retreat to the seven island nation of theirs where future directions will be given, Meanwhile, all the probes which were left on top of each island were given weaponization permission to kill anyone who disturbs the peace order thus putting limitations to Chaos which was happening all around the world.
Soon all his forces gather and Leo announced the list of islands where 2 members of the force would be sent to who will ensure peace on the Islands and introduce and democracy, education system and such to the normal people there. After the complete survey of the world, Leo had estimated 956 islands are present on the planet which were divided into 2 parts by the red line, first ending at Mary Geoise and then journey to final island Rafteal. Only around 500 of the island were inhabited by people with only 400 or so were Marine were present with 170 or so being part of it forming world government while the island which was not part were either hidden or were in such state which didn't interest the World government but still have some influence in them in one way or another. Thus 1000 member of the alliance were dispatched with criteria which would be best suited for the island and its condition. Language difference was also cracked by the probes which had deciphered it while observing the islands for years.
After dealing with the matter of public, Leo instructed the remaining 1080 to formulate a team of 3 which will work on the next part of the plan.
The 6 surrounding Islands were connected via bridge to the center Island and then Weaponized with Nuclear warheads created via Arc of embodiment. The members of Marine, Kaido, Big mom and Blackbeard forces that were captured were hanged from these bridges in such a manner that they were submerged into the water and were under the constant watch of sea kings from beneath while their DF power was useless in the water and without either leg or hands to do something making escape utterly impossible. Instructions were sent to both the shadow team with CP unit and Arcnologia in Marine to let all the forces infest with nanotech. the secondary shadow unit was also sent into the Mary Geoise who were then using Arcnologia authority placed under Celestial dragons directly as their servants, the secondary shadow unit infected all the celestial dragons with the unit with Nanotech, Leo's aim was simply to end the conflict in one go he created 10 backups using various weapons and such in preparation of the final fight as he didn't know what to expect from the lesser god of this world or its control over the heavenly energy which was one of the main reason's why he didn't eat any devil fruit, He didn't want to have any drawbacks while fighting the final battle.
The 2 person team went on to each island and multiplied the probes in the sky by 5 and introduced the Order of Roger, All kingdoms were given 2 choices Follow the order or Fall due to order. Many kings and big pirates in there arrogance chose to fight the order believing that 2 people send before them didn't have the capabilities to fight their entire nation or armies but even before they could reject or surprise attack the 2 people team, the probes in the sky erased the entire Kingdom via Nuclear weapon. Islands were whipped out of existence by the probes.
Leo had neither the patients nor reason to negotiate with people. The probe was present there for more than 10 years or so thus Leo using various AI who was in charge of the Probes knew the value of each island and nature of the people on it. The people who were found to be useful or somewhat innocent such as Children's and such were collected and secured by the two men team whose main mission was such. Out of 500 islands, around 300 after watching the fate of the Marines and with the help of Whitebeard and Shanks who acted as peacekeepers agreed to join and come under the banner of the order. 120 islands which were in conflict in some manners and refused were destroyed with innocent people being rescued. 80 Islands that were hidden from the worlds that even the Marine didn't know about were negotiated with and made to join the order.
Meanwhile, The five elders under the command of IM instructed all their CP units to go and infiltrate Leo's forces in some manner but any ships which would leave the Mary Geoise were destroyed by the Helicarrier which Leo had placed around the entire Mary Geoise trapping it into a bubble. Luffy and ace were sent to train under shark and whitebeard respectively. Revolutionary forces also stopped all its operations to watch the work of the order. IM or the lesser god due to his impositions and hunger of power order the Elders to find a way to find and end Leo and his forces to re-establish the order of world government.
Vagapunk, the top scientist of the world government was also put under the hunt list by Leo, Sengoku under the effect of Leo's powers revealed that Vagapunk was kept in secret within the boundaries of Mary Geoise under the constant eye of the elders and thus was hidden away from even him. Arcnologia was instructed to look into the matter of Vagapunk.
The forces of order took about 2 months to complete the formation and then making nations join it. Leo completing all preparations decide that the time for the final war is here. Order all his men to regroup at the 7 nation island while also sending orders to whitebeard and Shanks to gather all their forces. Whitebeard and Shanks knowing and seeing Leo's work of bringing order decided to join in. All the person who was either deemed weak were send back to the eastern sea by Leo which included Luffy and Ace.
Leo planned everything to the last detail 3 person team will go after an individual member of the enemy forces. Whitebeard and Shark forces will act as the first wave of attack which will draw the enemy out while Secondary wave consisted of Automata who will be the suicide boom squad of the force that will render and work to destroy all which are deemed as more dangerous during the first wave. Then the forces of Leo will start attacking.
With the battle of the Mary Geoise approaching All the alliance forces of Shark and Whitebeard were instructed to be gathered near the formal Marine Headquarters which was destroyed in the first war. Leo increased the number of Insight Helicarrier from 21 to 46 which were already modified as per the previous models. 10 Helicarriers were already present around Mary Geoise forming a bubble. 1080 personal were divided into 360 units which were then assigned to individual Helicarrier. Meanwhile, 900 members were assigned under the divided into 3 units of 250 under Leo, 300 under Madara and 350 under Ranju who will attack by sea using the main battleships which were used in Marineford and other wars while 33 subdivisional ships were given to Automata who will use them to fight off the enemy forces.
As per the information Arcnologia had provided Leo, the forces which were hidden in the Holy Land Marijoa numbered around 9000 strong while Sengoku also informed him that Elders were also in possession of one of the ancient weapon Uranus which is capable of destroying any island it is used on. Arcnologia had also sent information regarding the weapon describing it as a canon of the sort which gathers heavily energy from the surrounding and releases it in focus destroying everything which it hits.
Leo instructed all his Helicarrier forces to move out and gather within the Helicarrier which were already present there while he along with his 3 main battleships and Automata forces moved to Marinford to join Whitebeard and Shark forces.
