Compared to Istanbul, it is clear that no other city in the Safavid Empire, including the capital, was of that size. Therefore, when preparing for a blasting attack, the 600 naval blasting shells within a continuous range of 20 miles, even though the power of a single projectile was much smaller, was still not completely concentrated in the area of Isfahan's outer defense line, and some of the enemy's barracks in the vicinity of the city were also prepared for the blasting attack under the condition of increasing the amount of charge and reinforcing the projectile shell to a certain extent.

Because training is more adequate in peacetime and even wartime. The prepared projectiles were also of higher quality this time, so when the continuous blasting attacks were unfolded, the precise lead explosion control not only ensured that the three hundred or so projectiles covered the enemy's troop concentration area in the adjacent city wall defense line, but also effectively covered the "inner defense line" at a distance of about sixty or seventy paces

When the sky was just dawning, the explosions that unfolded one after another seemed to be neat thunder, and two halo-like things exploded near the entire outer defense line of Isfahan, and the violent sound and even the explosion wave intertwined with each other to form a joint force, so that the officers and soldiers of the Safavid Dynasty on duty were either blown up in the flesh and blood, or lost their reaction for a while under the loud sound and vibration. At about the same time, attacking teams from all directions began to blast the city, making it easy to do so when most of the defenders near the walls were almost incapacitated. There weren't too many shouts of killing, just the distinctive explosion of shotguns, black powder grenades, and even the terrifying sound of scraping through the air.

In this way, a total of 70,000 standing troops and even 50,000 mobilized troops, a total of 120,000 troops, soon suffered a devastating blow under this series of explosive attacks and the subsequent purging attacks. The casualties and losses exceeded 100,000.

And that's not all, a lot of artillery and even trebuchets and other defensive equipment that had been hoarded on the front line near the city defense also had a chance to lose out in this situation, and the defenders of the entire city suffered a heavy blow again in this round of confrontation, and their strength was greatly reduced.

Before the sky was fully lit up, such a powerful blow also caused some forces in the city to retreat one after another near the city's defense line. Taking advantage of this opportunity, the new guard battalion did not stop, redeployed a lot of artillery and even baggage as quickly as possible, and occupied the entire periphery of Isfahan City.

Under these circumstances, as the sky began to lighten, direct artillery fire from all directions on the castle soon took control of a distance of about five hundred paces within a mile and a half in the direction of the city wall. At this point, most of the remaining resistance forces in the enemy city, which was originally about eight miles in radius, had to be pushed into an area of about three or four square miles, which was difficult to effectively and directly cover within the range of artillery attacks.

It was under such circumstances that the continuous artillery preparations were resumed. Compared to the reconnaissance hot air balloon in Istanbul, which guided the artillery to carry out projectile attacks, the efficiency of direct fire at a distance that was not too long was significantly improved. At least it can launch a direct attack on some of the larger building targets.

In the next five hours, about 10 hours, the 200 steel-clad guns attached to the team fired more than 40,000 shells one after another, of which about 60 percent were solid shells specifically aimed at building targets, and about 40 percent were super heavy shotguns of about 67 taels or a dozen taels.

Under the relatively more precise firing, even the fire spread out at a distance of about two or three miles was finally extremely effective, and the remnants of the enemy who retreated into the central area suffered more than 50,000 casualties in a short period of time.

Of course, these losses were not entirely caused by the gunners, and the officers and men of the new guard battalion that had been pushed forward to the area of the blockade line also repelled the enemy's attacks many times throughout the day, inflicting tens of thousands of casualties on the opponent.

At this point, the opportunity to obtain decent terms of surrender through recalcitrant resistance no longer seems to exist. In order to save firepower to the greatest extent and avoid excessive casualties, Xiao Xuan still gave the opponents in the city a chance to surrender at this time, and restricted the defenders in the city to unconditionally surrender in the designated place before dark.

It was different from the resolute resistance that had been brought about by some drastic measures in Ottoman territory. In this desperate situation, some people, from Abbas II to the Prime Minister and even the Presbyterian Church, finally chose to surrender in the face of this almost irresistible firepower, from the armed people to the regular army, a contingent of about 90,000 people finally came out, abandoned all weapons and equipment as required, and began to be fully screened and questioned, and the hiding places began to be checked.

Although it is much less than the amount of land floating wealth in the area around Istanbul, the army from Isfahan is still very fast to live all kinds of hard currencies worth tens of millions of taels of silver and even craftsmen of a small scale.

In this way, in the summer and autumn of the nineteenth year of Chongzhen, taking advantage of the end of the typhoon season, the concentrated cargo ships carried hard currency with a total scale of about 60 million taels and even other goods worth about 80 million taels embarked on the journey home. In order to ensure that there were no accidents with these goods, Xiao Xuan finally decided to take the risk of returning by water.

When the fleet was in the South China Sea, it was still unlucky to encounter a storm at sea, but fortunately, it seems that it was already autumn, and the storm did not cause much damage to the entire fleet. Finally, in late autumn, a large fleet of ships arrived in the Matsue area.

In addition to the fleet led by Xiao Xuan himself, a large number of sea ships carrying grain and even other materials also arrived from many places such as Nanyang, Tianzhu, and Dongying.

Therefore, in the entire nineteenth year of Chongzhen, a total of 190 million taels worth of goods were transported in. If we exclude the "victorious dividend", that is, the part that is not sustainable, there are also about 150 million taels of overseas colonial income that have been sent. On average, the benefits received by each population in the sea are worth about one tael. The huge benefits brought by such gains have also begun to unconsciously change the value system of the whole of China, which seems to be somewhat left-leaning since ancient times. To a large extent, the meaning of the soldier and even the Son of Heaven also has a completely different connotation from the past.

Of course, what few people are proud of is that this seems to be a long way from Xiao Xuan's goal.
