The Dahan naval fleet departed from Cam Ranh Bay, continued south, and then turned west.

It has gradually entered the border area between the Ninan Kingdom and the Funan Kingdom, and the relationship between the two largest countries in Southeast Asia is very delicate.

Liu Bei's Rinan Kingdom was built on the basis of inheriting the original Linyi Kingdom, and the Linyi Kingdom and the Funan Kingdom were mortal enemies for hundreds of years.

However, the Ninan Kingdom became an ally of the Han Empire, and the Funan Kingdom was also an ally of the Han Empire, but the two sides had many conflicts of interest in this area, such as territory, such as coastlines, islands, and more importantly, maritime trade.

The Han Empire could only maintain neutrality between the two of them, with Cam Ranh Bay in Ninan and the more important naval base Pizong in Funan.

With the help of a large number of local natives, Pizong has built a large military port and a large number of camps, docks, ship repair yards and other ground buildings.

A small fleet of four Chang'an-class warships and four reconnaissance ships are stationed here all year round.

There are also two large coastal batteries built around the base, which are built by the navy as a permanent base, and the geographical location is extremely important, and it is also exactly halfway from Panyu to Minagara, so it is essential to supply fresh water, food, ammunition, etc.

In order to develop and build here, there are many Han immigrants and local natives around the base to carry out tuntian construction.

Now that the influence of the Funan Kingdom here has become smaller and smaller, and the power of the Ninan Kingdom has gradually penetrated in, how can the natives of Southeast Asia compare to Pang Tong's strategy?

The Grand Fleet is not yet fully stationed, after all, there are too many of them, and most of the ships are still anchored in the open sea of Pizon, supplying fresh water and food, which can still be guaranteed.

And when you get here, you don't need a guide from the Nisan Kingdom, the Han Navy can navigate by itself, and further west from here is the range of activities of the Indian Ocean Fleet.

In the Indian Ocean, there is no fleet that can be compared with the Han navy, and even pirates hide far away when they see ships flying the Han flag, and they dare not rob the merchant ships of the Han Dynasty.

Lu Su is not merciless in his attack on pirates, and he has always chased them to the ends of the earth to exterminate them.

The Indians, Kushans, Arabs, and Persians on the coast of the Indian Ocean are all submissive to the Indian Ocean Fleet of the Han Navy, and it is already a situation where the Han Navy is dominant.

The Pizong garrison sent a reconnaissance ship and several sailors familiar with the shipping lanes to serve as guides for the Grand Fleet, and Gan Ning did not stop long, but continued to move westward.

This time the Grand Fleet was moving exactly along the same route as the first attack on Minagara, and the ports in the Indian Ocean along the way did not dare to let the Grand Army anchor and replenish, they had never seen such a large fleet.

The greatest advantage of the fleet along the coastline is that it can avoid storms in the Indian Ocean, which is not much more frequent than the Pacific Ocean, but the coastal areas are much calmer.

Minaggara is one of the largest ports in the Indian Ocean, and almost all of the expeditionary fleets of the Han Empire were anchored in the bay, and of course many merchant ships were driven out of the port and anchored in the new port area.

Lu Su had already rushed back to Minaggara from Alexandria, where he personally greeted Lu Bu's arrival, along with Osidemos, the number one general of His Majesty Mags of the Kushan Empire.

Although the Kushan Empire had essentially split into two parts, the Eastern and Western Empires, the Han Empire was still officially recognized by the Kushan Empire, which was ruled by Mags.

Lu Su reported to Lü Bu the latest information on Egypt and the Mediterranean region, especially the recent situation of the Roman Empire.

The Roman Empire was doing its best to build a new navy, and the coastal ports of Italy and various ports on the Greek peninsula were all working hard to build new warships.

The Roman Empire even donated most of the statues in the temples to smelt steel and bronze, and to build cannons and muskets.

The Romans obtained from the Persians the blueprints of the Chang'an-class, especially the watertight compartment and keel method, and captured Persian shipbuilders.

Although these Persian craftsmen were not as skilled as the Han craftsmen, they had systematically learned the shipbuilding methods of the Han Dynasty, so they quickly helped the Roman Empire build the first new ship of 500 tons according to the drawings.

However, the Romans were not satisfied, they already knew that the Han Dynasty had a huge ship with greater tonnage and fierce firepower than this kind of warship, so they asked the Roman and Persian shipbuilders to develop larger and newer warships as soon as possible.

The easiest way is to enlarge the Chang'an class in equal proportions, but how can shipbuilding be so simple?

The 1,000-ton warship, which they built in equal proportions, was blown down and capsized by a strong wind during sea trials, and many people were killed and injured.

However, after all, the Romans were also a country with an advanced civilization, they just didn't have advanced ideas, and now with ready-made drawings to guide the way, the Romans quickly figured out a set of their own.

After several failures, the Romans finally succeeded in building a thousand-ton sail warship, and could guarantee a salvo of artillery on one side without affecting the hull structure and stability, which can be described as rapid progress.

The army of the Roman Empire was changing rapidly, and in order to prevent the invasion of the Han Dynasty, they formed two large armies, the eastern and western armies, which were responsible for guarding Rome itself, that is, the Italian peninsula.

The Eastern Army was stationed on the Greek Peninsula, and the headquarters of the Legion was set up in Byzantium, where it practiced day and night to prepare for the enemy.

The Emperor of the Roman Empire, Caracalla, personally served as the commander of the Grand Legion of the West, responsible for the defense of the homeland.

Lucis was the commander of the Grand Legion of the East, which had sixty Roman legions and auxiliaries, in addition to some northern barbarian armies as auxiliaries.

The Roman legions have all completed the armament of muskets, and most of the auxiliary legions have also been replaced with muskets, and the rest are mostly shield bearers.

The army of the northern barbarians maintained the characteristics of their cold weapons, with 30,000 cavalry, including 10,000 heavily armored cavalry, and 30,000 crossbowmen, wearing leather armor.

However, I heard that the archery skills of these barbarian crossbowmen are very good, and they are nine out of ten within a hundred zhang.

Lucis believed that if the Han Empire launched an attack, it was very unlikely that it would attack Italy mainland directly from the sea, after all, the navy would win or lose.

Nine times out of ten, it would have to be fought through the straits of Byzantium, and it would be safer to attack the Roman Empire by land.

Lucis's lieutenant Marcus agreed with him, and asked himself to be the governor of Thrace, guarding Adrianado behind the Byzantines, ensuring the rear of the Great Army and preventing the Han army from rushing through the Byzantines.
