"Old squad leader, take a look. Put the oil paper in and unfold it. The iron plate is at the innermost part. The TNT explosive package is placed in front of the iron plate. This is..."

In Hufeng Village, Hu Changyi taught the senior squad leader step by step how to set up the directional blasting device, trying his best to make the senior squad leader see carefully and listen clearly.

Having learned from the experience of Qigen Village, and because the 343 Brigade provided 5 telephones and 8 dry batteries, Hu Changyi did not arrange a one-time detonation position covering the entire line.

This time, he selected 14 suitable nodes and arranged 14 explosion zones in this more than three-kilometer ambush area. In each explosion zone, 3 to 5 directional blasting devices merged into a bus.

Because the selected explosion point is far enough away from the mountain road, the directional mines on each node can cover a road section of 100 to 200 meters.

All in all, in the more than three kilometers of river valley, there is only a little more than one kilometer of road section that is not covered by directional mines.

Then, those combat units with elm cannons and large rifles equipped with shotguns took advantage of every opportunity to set up ambushes in these blank areas.

As a result, the entire canyon was covered by this weapon that could fire densely covering projectiles.

And luckily, with so many people operating in and on both sides of the valley, the Japs didn't actually send out sentries to patrol or come out to take a look.

Perhaps the Japanese thought that the Eighth Route Army had already evacuated along with Guo Preserved's troops? Anyway, they didn't care about the situation here.

At this moment, it was already dark, and the Eighth Route Army ambushing on both sides of the valley had chosen their ambush areas, waiting for the Japanese to come.

"At the latest the day after tomorrow, the Japs' troops will pass through here! So, everyone should quickly find a place to rest and get into combat positions early tomorrow morning!"

The messenger at the brigade headquarters sent new orders to each ambushing company, and then each company arranged for the troops to take turns to rest after leaving enough soldiers to guard the front line.

After Hu Changyi taught the old squad leader how to deploy directional mines, he separated from the old squad leader again. Although he was reluctant to let go, we all had their own units and could only separate. When was the next meeting of the semi-automatic meeting?

The guerrillas were assigned to the Seventh Company again, on the hillside south of the valley of Zhongshan Village, only about 200 meters away from the mountain road south of Zhongshan Village on the north side of the valley. The Seventh Company was to the east of the guerrillas, where the valley was more

Narrow, it is the main area for ambush.

"Well, the consumption of iron sand is too great. We must get some iron sand to reserve when we have time!" The guerrillas were arranged to rest in the back.

Hu Changyi, who fell down on the hillside after eating, looked at the twinkling stars in the sky, and then thought about the iron sand that was no longer in the hands of the guerrillas, and couldn't help but secretly lament the lack of supplies.

"I remember reading a novel that traveled back in time to the Northern Song Dynasty. The protagonist built some basic military industrial facilities, and one of them mentioned using crucible colanders to make steel balls. I remember in this chapter some readers said that the steel balls made like that would have a

A little tail or something.”

"So, if you have time and opportunity, give it a try. Don't make any steel balls, just iron balls. The diameter doesn't need to be too big, 3 to 5 mm is enough."

"With that thing, whether it is used to make directional mines, or used as fragments in landmines and grenades, it is a very important material! And even if it is irregular, it is not a problem to have a small tail, but it increases the number of

Lethality. So, you must try it..."

After thinking about these things, Hu Changyi stopped wandering outside and returned to his tent in the woods to prepare for sleep.

Because Dr. Sun was here and Xing Dezheng was still a wounded man, the guerrilla tents had already been set up. The tent area of ​​the friendly forces would become a temporary field medical station, responsible for rescuing the wounded on the battlefield.

Although he knew that there would be fighting tomorrow and the day after tomorrow, he needed to take a good rest to accumulate strength, but Hu Changyi couldn't sleep, so he went outside the tent to breathe some fresh air and saw Zhao Fengnian sitting on a stone.

"Uncle Fengnian, shall we follow the main force of the regiment in the next step?" Hu Changyi asked.

"Yes, Lao Xing can't act on his own here yet. We still have to follow the main force of the group for the time being! But then the main force of the group may not be able to take care of us, and we men will have to rely on ourselves!" Xing Dezheng said.

"Well, I promised Captain Li to make the grenade as soon as possible. We have to think about this next step. The brigade headquarters has also found some workers, and we have to find a way to arrange them!" Hu Changyi said

.

"Don't worry about these, the regiment will make arrangements for you! Just think about how to get the grenades out in large quantities and quickly!" Zhao Fengnian said with a smile on his face in the dark night.

"Hand grenades are easy to make, but increasing their power is difficult! We still have to find a way to make some black powder particles. Best of all, we still have to get better explosives!" Hu Changyi said.

"Don't worry, the organization attaches great importance to the development of military industry! I think we had our own arsenal in the Soviet area, but it disappeared later! We still have some old military industry technicians, and I'm afraid these people are being transferred to our regiment!"

Zhao Fengnian said.

"That's a good relationship! Those people all worked with my father back then, right? I haven't seen them for several years!" Hu Changyi said.

"Okay, go to bed early. I hope there will be more little devils. If they don't come, I'll be sorry for those directional mines you worked so hard for!" Zhao Fengnian said with a smile.

"Well, I also hope to come more! Go to bed..." Hu Changyi said hello and returned to the tent area.

"Brother Ergou, tell us about sheep herding? You said that if our guerrillas have two bases, how about raising some sheep by ourselves?" Hu Changyi found Zhao Ergou and had a cordial conversation. During the conversation, he also

Don't forget to pass on Zhao Ergou a proficient level of 38 big shot shooting skills.

Yes, there are still many people in the guerrillas who have not been transferred to the skills by Hu Changyi, and the design level is very poor. In order to increase the combat effectiveness of the guerrillas, Hu Changyi can only activate the "shoulder tapping trick" again to transfer skills to several guerrillas.

This time Hu Changyi chose Zhao Ergou, Zhao Erbao, Zhao Yuanbao, and Liu Shuquan. By the way, he also spent 40 merit points on Diao Qixian's proficiency-level bayonet stabbing skills, and also spent 50 merit points on buying one for himself.

Proficient in level-one bayonet stabbing techniques.

"Ding... the host spends 40 merit points... the host's current merit points are: 2417 points, soul energy 895/10000."
