Bright Sword Military System

The Japanese's retreat of [-] kilometers was just the beginning. Then the Eighth Route Army used several tactics to fight for several days, forcing the Japanese back a hundred kilometers.

Only then did the Eighth Route Army stop to take a breath.

There are at least several advantages to defeating the Eighth Route Army along the way:

The first is to place Chifeng, a strategic location in depth, so that it is not as vulnerable to enemy attacks as before.

The second step was to add several lines of defense, including the transformation of the Japanese defense line, and a total of five lines of defense were built.

Again, it is to give the militia troops a chance to train... Many problems were exposed during the attack, mainly the problem that the militiamen rushed too hard when they started the war.

This phenomenon is common among recruits. Perhaps out of excitement or revenge, the commander rushes forward with all his strength as soon as the commander gives the order to attack. As a result, he loses the strength to move forward within two seconds.

If it is a charge or general attack on the enemy's position, there is no problem in charging like this.

But this battle is a sustained attack to push the enemy's front line south. It has to be fought for several days. To charge with all your strength from the beginning is almost like sprinting with all your strength in the early stages of a marathon.

The battles of the past few days can be said to have taught these new recruits a lesson.

The most important thing is to solve the problem of Japanese soldiers crossing from mountainous areas.

Or it can be said that Wang Xuexin's initiative disrupted the Japanese's combat plan.

Now even if the Japanese penetrate, they will not be able to hit Chifeng directly in one step. After all the hardships, their intersecting troops may only pose a threat to one of the Eighth Route Army's defense lines.

This allowed Wang Xuexin to implement his "petroleum plan" in the north.

Wang Xuexin first asked people to find a piece of terrain suitable for defense... It was a basin more than [-] kilometers north of Xinjing near the Daxingan Mountains. It faced Shandong on three sides and connected to the open plains to the northeast. There were about a hundred households living in the basin called Ping'an Village. , meaning peace and tranquility.

This place is obviously easy to defend but difficult to attack. As long as a trench is built in the northeast and the artillery and machine guns are placed on the high ground... with sufficient ammunition, not many Japanese can get in.

At the same time, the water source in the village is still a well.

The good thing about a well is that it has no upstream water source, so it is impossible for the Japanese to cut it off at the source or poison it.

The only bad thing is that the ventilation in this basin is not very good and it is easy to be attacked by Japanese gas bombs.

If this gas bomb were hit inside, I'm afraid it wouldn't be able to float away for several hours.

However, this problem is not difficult to solve. Wang Xuexin drew a line outside the basin with his finger and said: "Deploy two more defense lines outside here and push the defense line five kilometers out!"

The range of the mortars used by the Japanese to fire poison gas bombs is 3.8 kilometers, which makes it difficult for the Japanese poison gas bombs to hit the basin directly.

In addition, the Eighth Route Army's artillery reconnaissance radar and artillery can also be deployed on high ground to suppress the Japanese.

The basin in the rear is actually equivalent to the supply center and ammunition depot of the front line of defense. It can be advanced, attacked, retreated or defended.

Finally, the garrison was equipped with gas masks, and the basin was ready for gas prevention.

After everything was ready, Wang Xuexin sent the exploration team to Ping'an Village.The next day, Wang Xuexin made an appointment with the geologist who came from Yingjiang.

The leader is a professor named Imos. He has a beard and looks like he is in his fifties... However, it is not easy to tell the age of Westerners. Their facial features are more three-dimensional, and the traces left by time on their faces are relatively different. obvious.

"Professor!" Wang Xuexin asked straight to the point: "I wonder what you think about the theory of oil generation in terrestrial phases?"

Imos glanced at Wang Xuexin with a mocking look and said, "I am their leader, so I know what is going on! This is just a show, isn't it?"

"Maybe!" Wang Xuexin nodded.

"So why don't we just do it!" Imos said: "I mean, skip the unnecessary steps, you do your thing, I will do mine!"

"Of course!" Wang Xuexin replied calmly: "But, I'm worried that the theory you put forward is not enough to deceive the Japanese, so I want to hear it!"

"Okay!" Amos replied helplessly: "Let's put it this way, I don't believe a word of the so-called 'terrestrial phase produces oil' theory, but in order to cooperate with your actions, I will publish the theory you want!"

Wang Xuexin saw a hint of reluctance on Amos's face.

At first, Wang Xuexin felt a little strange. Why was he unwilling to serve the country?
But after thinking about it, I realized that this matter involves academic issues.

One day, the moment Amos's remarks are proven to be false... No matter for whatever reason, he will be stained with "academic fraud," and others will only half-believe what he says in the future.

Wang Xuexin found it a bit funny. Imos must have never expected that the theory he published would be truly correct and about to be confirmed.

"Are you going to publish China's 'terrestrial oil generation theory'?" Wang Xuexin asked.

"You can say that!" Amos nodded: "Otherwise, what else would there be?"

"Perhaps we can add something different!" Wang Xuexin pushed the topographic map of Ping'an Village in front of Imos, pointed with his finger, and said, "Basin, professor, do you think there may be oil in the basin?"

Amos glanced at the map and seemed to understand something: "Of course, there is probably oil in the basin, even though it is far away from the coast!"

"Why?" Wang Xuexin asked again.

"Uh..." Amos was at a loss for words. After all, he needed to have a complete and convincing theory, with strict logic and no loopholes. This was not something that could be imagined in a short while.

"Is there a possibility?" Wang Xuexin said while drawing carelessly on the topographic map: "The reason why a basin is a basin is because its middle part has continued to sink for a long time. This makes it continue to remove plants growing on the ground. And the huge thick sediments formed when animal carcasses were brought into the ground, and over time these sediments formed oil!"

Emmaus's eyes couldn't help but light up, and he looked at Wang Xuexin with a bit of surprise.

Then he thought carefully, nodded and said: "Yes, it is completely possible!"

"In addition!" Wang Xuexin added: "Basins are often rich in groundwater, and oil is lighter than water. The flow of groundwater will bring these oil particles to gather higher in the waterway, which is the anticlinal direction of the basin. So Are you right?"

These words shocked Professor Imos to the extreme. He was stunned for a while with his mouth half open, and then asked: "You, you... also do research on geology? How did you come up with this!"
