Under the city of Jining, the Third Army took the initiative to shrink the front, giving up most of the southern territory of Shandong Province, except for some resistance in Xuzhou and other important cities, delaying time, the rest of the time the Third Army never thought about the gains and losses of one city and one place.

This is similar to the previous Ming Dynasty's various soldiers and horses against the attack of the Hong Dynasty's army, but it is completely different after careful study.

The strategic similarity between the two armies before and after is that when they retreat, they will coerce the people in the garrison to retreat together, and the walls will be cleared; But the difference is also very big, that is, the Hong Dynasty army really wants to garrison a place to resist, so the Hong Dynasty army wants to capture, but it needs to damage countless soldiers at the cost of damage, and even if the Hong Dynasty army uses Xuzhou City as a base to resist the Ming army's attack, it should not be dragged when it should be abandoned.

Although, among them, the Ming Dynasty army captured more than ten artillery pieces of the Third Army Artillery Regiment, plus the original Ming Army's own, and finally when attacking Xuzhou, the Ming Dynasty army completely suppressed the defenders of Xuzhou of the Third Army for the first time in terms of the number and power of artillery fire.

However, it is undeniable that the army commanded by Zhang Huangyan actually used artillery under the city of Xuzhou, although the city walls and gates of Xuzhou City, which had been broken and had not been completely perfected, were broken after more than ten days, but if they really had to dig deeper, if the huge territory in Xuzhou City was used as a position, the officers and men of the Third Army may not be able to continue to stalemate with the Ming army in the city for more than ten days, giving the Ming army huge casualties.

However, on the day when the city wall of Xuzhou City was broken, the Third Army suddenly broke through from the city without losing most of the territory in the city, and did not think about fighting the Ming army in the city.

It wasn't until it arrived in Jining City, when the Third Army contracted the defensive line in its hands, oh hello, and had nearly 40,000 troops in its hands at this time, that the army commander Kong Youde ordered to be stationed on the spot in Jining City, and various defensive offensives were quickly built in place.

However, at this time, more than two months have passed since the time of Xiangcheng's attack and defense of the battlefield, and the time has entered the time of summer, and it is ten minutes in May.

On the city wall of Jining City, many places seem mottled, which is the fortifications that have been rebuilt with cement and steel in these years after the Third Army opened the Jining city defense with artillery fire.

The blue bricks and ashlar are intertwined with cement concrete, and they look like patches patched together in tattered clothes.

But don't underestimate the city walls built of these concrete, with the Hongchao R&D Institute in recent years, there is no difference between the cement of this era and the cement of later generations, perhaps just some special cement materials in later generations.

At this time, on the city wall of Jining City, there was a cannon sticking out of the city wall, almost at the same level as the horizon.

In the watchtower above the city gate, Kong Youde and Bai Guangen and other generals came up to observe at leisure, and only killed the Ming Dynasty army under the city during the day today.

"This is a bit excessive, they Ming Dynasty people are unforgiving, occupy so much of our territory, now in their hands Oh hello, at this time the number of troops is only 150,000, and they still want to attack our Jining City, where do they get their confidence?"

Since Bai Guangen was released to abandon the dark and surrender to the Ming Dynasty to join the Hong Dynasty, returned to the Military Department of Bengang Academy to re-study, and graduated with good grades, he was arranged to return to the Third Army and serve as the commander of the Fourth Brigade of the Third Army.

Although in the Ming Dynasty, he Bai Guangen was already a military attache of the second grade, and he could be regarded as a powerful officer in any place, but when he arrived in the army of the Hong Dynasty, he could only control one of the brigade commanders of 10,000 soldiers and horses, and the gap was self-evident.

Under the subtle noise of the dual-electrode thruster like a buzzer, Wuzhi 30 was like a ghost in the night sky, dragging its slender blue ionic wind tail and moving quickly in the direction of the Northwest Institute of Biology in Xinjing City.

In the cabin, together with Zhang Song, the nine members of the Falcon Commando Team are all closing their eyes at this time, except for the guy Maoyan, as a sniper who should be the most calm, he is the most lively in the team, and the most idle guy on weekdays, even at this time, he does not forget to look around, sometimes picking up the game console in his hand to play two, and sometimes overlooking the entire night sky through the fuselage glass.

"Five kilometers from the target, you still have three minutes to prepare!"

In the cab, the driver reminded them in time and pulled Zhang Song back from closing his eyes and recuperating.

"Dress up!!"

"Prepare for a plunge!!"

The well-trained team members quickly completed all the preparations for putting on protective suits and equipping them with weapons, and as the three cables hung down, the nine team members glided down the open hatch and landed smoothly on the open grass.

Wuzhi 30 drew a circle above his head, and the pilot gave instructions to the cabin crew through the headset.

"Action!"

The helicopter hovered at a height of 10 meters, and after Zhang Song gave an order, several team members rushed out and climbed a cable that fell from the sky, skillfully descended to the ground, and made a guard action.

Ninety seconds later, Wu Zhi 30 disappeared into the night sky with a slight hiss that pierced the air, leaving only Zhang Song and his party of nine warriors on the open ground.

"Determine your bearings and go!"

Zhang Song did not stop on the ground, and after judging the position on the wrist brace indicator, they walked quickly and silently along the position of Zhang Yao in the indicator.

The tallest building in the institute is only four stories high, and due to safety considerations, there are no more buildings blocking the surrounding area, which makes it look extremely empty, which brings great help to Zhang Song's actions.

"Cat's eye, you and glasses are so hot, asking you to find the commanding heights and control the surrounding environment."

Soon arrived at the main building of the research institute, Zhang Song began to assign tasks.

"Understood!"

Chen Liang, who is giggling on weekdays, looks particularly quiet on the battlefield at this time, which makes people feel a little stable.

"The others came with me to the institute."

"Remember, the virus has leaked in the research institute, and everyone must remember to ensure that the protective clothing on their bodies is not damaged when you act!"

"Understood!"

The six team members replied in a low voice.

The hall of the research institute was empty, and according to the information obtained before, the staff on the ground building had been placed on the fourth floor of the building to check their bodies, and Zhang Song's target was in the underground laboratory more than a hundred meters deep.

Through the temporarily assigned permissions, Zhang Song and the others started the elevator to go deep underground, feeling the feeling of weightlessness brought by the rapid sinking, but Zhang Song and they had already arrived at the corresponding floor in half a minute.

"Click!"

The sound of the safety bolt opening was completed before the elevator opened, and as the elevator door slowly opened, Zhang Song and several team members around him had already raised their assault rifles, aiming beyond the elevator door.
