At noon, the temporary headquarters was set up in the commanding heights of Tengchong City, Wenxing Tower, and the grass mustard Taro was deploying the city defense focus to adjust the center of defense, and the well-trained Japanese army was rapidly deploying the defense according to the order, and the Feifeng Mountain in the south of the city had been occupied by thunder, and Tengchong had lost the barrier that could be relied on, so the grass mustard had to readjust the center of gravity of the defense, and more soldiers were arranged in the bunker group to strengthen the ground defense. Thunder has a powerful group of heavy artillery, but Cao Kei believes that the bunker group outside the city will not be destroyed by heavy artillery, and he believes in the strength of the Imperial Engineer.

In Zhao Zhi's headquarters outside the city, except for Zhao Zhi, who was still leisurely drinking tea, all the people were anxiously waiting, in order to attract the attention of the Japanese troops in the fort group outside the city, several feints organized by Thunder had certain casualties. Although few soldiers were actually killed, the unfavorable situation of the battle made many Jewish soldiers feel emotionally manic, and the officers feared that the troops would eventually lose control.

"Okay, since you don't want to wait, let's start" Seeing that the officers in the command headquarters had begun to fidget, Zhao Zhi put down his teacup and immediately gave the order for a general attack. According to the prior contact signal, the 105-mm American-made howitzer group fired several sets of smoke bombs into Tengchong City, and used the smoke bombs in the siege battle.

"Ready, ready, they're going to attack" The sharp drop in visibility panicked the Japanese officers in charge of the city's defense, and some of the officers and commanders shouted hysterically, making their soldiers wide-eyed and on guard. The sound of artillery shells breaking through the air in the sky gave the Japanese troops a very bad premonition, it was the sound of light mortar shells breaking through the air, and the enemy was carrying out close-range artillery attacks under the cover of smoke.

In the muffled sound of explosions, the Japanese troops had already begun to enter the bunkers according to the prior defensive measures, and in the eyes of the Japanese troops, the approaching artillery bombardment must have been the prelude to the onslaught of the enemy. What puzzled the Japanese army was why the enemy fired smoke bombs. Did they think they could block the view of the Imperial soldiers with smoke grenades so that their troops could attack? Didn't they know that the wind would blow away the smoke, not to mention that the enemy's smoke bombs seemed to be missed, and the bunker group outside the city still had a good line of sight, and any movement of the enemy army could be clearly seen in the bunker.

Cao Jiao took a cigarette from his subordinates, lit it and took a deep breath, believing that with the 2,000 Japanese troops in Tengchong City, the city was connected to the incomparably strong city defenses, especially those households. The streets and streets are the same group of street forts, dark trenches, and bunkers, and he is absolutely confident that he will hold on for 7 days. Once reinforcements arrive, he will be the hero of the battle, and may even earn the rank of major general he has been dreaming of for a long time.

When the Zhaigongfang position fell, Cao Jiao had already sent a distress signal to the front army, and the front army instructed Cao Ji to defend Tengchong no matter what, and the reinforcements came back from Longling and Songshan. But one night passed, the situation changed, not only Tengchong was besieged, but even Longling and Songshan were also surrounded, not to mention sending reinforcements to rescue Tengchong City, even Longling and Songshan themselves could not protect themselves. Cao Jiao had to contact the front army again by radio, and half an hour later, he got a guarantee that the front army would send troops to help Tengchong, but Cao Jiao had to hold Tengchong for 7 days.

"Fire, fire" The machine guns placed outside Tengchong City began to shoot according to the officer's orders, and the rain of bullets rushed towards the bunker group of the Japanese army on the opposite side, and from time to time a few mortar shells or grenade grenades smashed over, coupled with the neighing and shouting of the Jewish soldiers lying in the trench, the Japanese soldiers who entered the bunker group shot back one after another, thinking that the enemy was attacking.

"Sir, as we expected, the Japanese army has already stationed troops in the bunker, but looking at their firepower distribution, it seems that the number of people is not too much" Xiao Ziyun, who ran in from outside the headquarters, was still carrying a telescope in his hand. This is Xiao Ziyun's own application to Zhao Zhi, judging the number of enemy troops according to the enemy's firepower points, this is a compulsory course for Thunder officers, Xiao Ziyun wants to learn more battlefield experience from those senior Jewish officers.

"Don't wait, order the fighters to take off" Several secret airfields have already been built on the east bank of the Nu River, and although they are still very simple, it is not a problem to take off and land fighters. The order was issued only ten minutes later, a bomber appeared in the sky above Tengchong under the escort of two fighters, the appearance of the fighter plane made the Tengchong Japanese army riot, but the grass mustard withdrawn from the Wenxing tower was still steady as usual, as early as when he was stationed in Tengchong, the grass mustard had already thought of the problem of air defense, he did not have air defense firepower, but he had people under him, so he built bunkers and fortifications at the same time, but also built a lot of air defense bunkers.

The bombers flying over Tengchong did not care whether the Japanese troops below had air raid bunkers or not, and they received orders to use new bombs to kill the Japanese monkeys below. Winters was now concentrating on the bombardier, and the smoke indicator area was approaching the center of his bombardier's scale. An experienced bombardier, Winters served in the British Air Force for many years, participated in a number of actual air strikes, and had little clouds over targets, good visibility, and no anti-aircraft artillery. There are no fighter planes, such an environment is obviously Winters' favorite, and after calmly pulling down the bomb handle, Winters is so excited that he yells in the headphones.

Four silver bombs fell from the sky, and the officers who were watching the battle in the headquarters were also holding binoculars, and Yan Wudao shouted excitedly, "It's down, the bomb is down, look, the bomb is down!" Everyone's eyes almost watched the bomb land, but everyone was surprised to find that the Japanese bunker group between Fengshan and Tengchong City did not explode. Before everyone could start speculating, the earth suddenly shook violently, and in the dense detonation of the white firelight, a large wave of violent contraction appeared in the distant air.

In the flames rising from the sky, bursts of violent shock waves mixed with suffocating heat Lang were rapidly devouring everything with the momentum that swept the heavens and the earth. These corrosive flames glowed with a scorching white light, as if the end of the world had come. With the end of the blast wave, the expected skyrocketing fire did not appear. The direction of Tengchong City was as silent as a dead city, and the steaming geothermal heat made people from miles away feel unbearable, and the forward troops reported that the temperature on the front was too high. The troops could not get close to the troops with breathing difficulties, and a Jewish company arranged at the front had to be withdrawn.

The breeze brought gusts of heat, but the officers in the command still didn't feel the temperature, and a cold, almost creepy feeling was spreading. Yan Wudao, who had always been brave and outstanding, also came back to his senses for a long time, and asked Zhao Zhi with a surprised expression on his face, "Sir, this is the new type of bomb you said?" "In the distance, the place that was originally green became pitch black at this moment, and the entire mountain was shrouded in steam, like the legendary Earth Flame Mountain, and Yan Wudao saw with his own eyes a Japanese steel helmet that appeared in the telescope turned into molten iron.

Zhao Zhi, who was also in shock, nodded his head and replied, "The effect of this new type of bomb is indeed very huge, and it is also greatly beyond my expectations, I didn't expect the power of this thing to be so great" The officers were excited with expressions, in their opinion, this kind of artistic conception into the actual combat of the new bomb is simply a sharp weapon for attacking the city, and it will be used directly when encountering the stronghold of the Japanese army in the future, which can be described as invincible.

Seeing that everyone's eyes were all focused on himself, Zhao Zhi said expressionlessly, "This new type of bomb is only in the experimental stage, and has not yet been mass-produced. And special shells must be used intensively in a small area, if prepared in advance. Once the Japanese are familiar with the characteristics of special ammunition, then the effect will be greatly reduced."

The power of the new Thunder bomb obviously exceeded the expectations of the Japanese army, most of the Japanese officers and soldiers hiding in the bunker fortifications died of high temperature burning and suffocation, because the air was heated and burned, although the Japanese officers and soldiers hiding in the underground fortifications avoided the attack wave and the flame heat, but could not escape the pervasive hot air, their respiratory tract was scalded by the hot and hot air and caused suffocation, their deaths were extremely horrific, many Japanese officers and soldiers used their fingers to break their throats to no avail.

The walls not far from the bunkers were burned by flames, and the Japanese troops hidden on the walls fled in all directions, while the Thunder troops scattered on the two flanks outside the city took the opportunity to launch a general attack. Enduring the boiling heat, the Jewish soldiers poured into Tengchong City like beasts along the gap in the dynamite-blown wall. The sound of intensive shooting resounded in the sky, and more and more Jewish soldiers entered Tengchong City, and began to divide and outflank the Japanese defense forces according to the pre-divided area, and the mercenary troops under the command of Yan Wudao naturally rushed to the front line.

The troops had already entered Tengchong City, but the officers who walked out of the headquarters and marched towards Tengchong City were stunned by the tragic scene in front of them, the bunker fortifications of the Japanese army had been dilapidated, there was no groaning of the wounded, and there were charred corpses and curling green smoke everywhere, the whole soil seemed to be burned, and people stepped on it, and their feet were hot and uncomfortable. "Okay, it seems that our loot is gone" Looking at the iron tools that have been turned into molten iron, the officers' faces can't help but show a trace of chagrin, the power of this bomb is not small, but this thing is too domineering, it actually destroyed the weapons of the Japanese army, and the loot will be a problem in the future.
