Yanping was captured, and the central part of China was relocated to the inner fortress of the Taihang Mountains, relying on a large army, air force, and complex terrain to deal with the possible attack of the Jean army.

With the transfer of the central organization, Yuan Hao and his MS research team also left Yanshan and came to a base located in the depths of Taihang Mountain.

The base was originally a strategic warehouse for the storage of obsolete munitions. Although the Earth Federation has been established, the envy, jealousy, and fear of Huaxia from other countries in the Earth Federation have made Huaxia's situation not very good. Driven by this sense of crisis, Huaxia people have the idea of thrift and thrift, and a part of the "obsolete" weapons will be sealed into the corresponding warehouses every year.

The base in Yanshan where Yuan Hao used to stay did this kind of work, and the base in Taihang Mountain where he is now is doing the same thing.

Mao Xinglan handed over this completely hollowed-out base to Yuan Hao, who took Sima and them to visit the environment of the base, and was surprised to find that this base could be used as a military exposition. The base's warehouses are dominated by army weapons, with equipment ranging from the late 20th century to the mid-21st century before UC, and then to the early UC weapons, which pre-UC 61.

After UC0061, the Federal Army carried out the so-called 60s Armaments Enhancement Program, which was actually also an armaments integration program:

In order to develop armaments and reduce logistical troubles, the federal army integrated the original three major weapons and equipment systems of the United States, Russia, and China, canceled a large number of army equipment and armed the army, carried out simple planning and upgrading, and determined the basic equipment of the federal army at present: Type 61 combat vehicles, Type 74 hovercraft, Panpan-class land warships, wired missile launchers, self-propelled assault support guns, and so on......

In short, after UC0061, the armies of the various member countries of the Earth Federation have the same equipment, except for the inner temperament, on the surface, the Federation Army has become a real one.

"So...... The weapons here are the last essence of the Chinese style...... It's a heavy nostalgia. Zhou Yunchang, who accompanied Yuan Hao to visit the base, said with emotion.

"Can all the weapons here be used?" Yuan Hao looked at these old grandfather weapons one by one, and it was said that he was much older than him, and suddenly asked such a question.

"......Naturally," Zhou Yunchang assured: "This is a state-level combat readiness warehouse, and everything in it has been carefully maintained." Although it is an old-fashioned thing, it is still possible to use it when it comes out. ”

"If that's the case...... Yuan Hao held his chin and muttered for a while, "Maybe there are some useful things in here that we can take out and use against MS." ”

As he spoke, Yuan Hao's eyes flashed with an inexplicable essence.

"What? Use these old grandfather's weapons to deal with high-tech like MS? You're not kidding, are you?" Yuan Hao's words made Zhou Yunchang feel very surprised.

"The key to weapons is to see whether they are suitable for use, not simply to say that they are not advanced. In fact, we are now in a situation somewhat similar to the old World War II. In this environment of pursuing 'close-quarter' combat, high-precision guided weapons cannot be used, and perhaps more primitive artillery is suitable for us.

Of course, in order to tear apart Zaguna's decent armor, the ammunition of these guns needs to be further improved. We need to make him even more murderous. Yuan Hao explained with a smile.

Zhou Yunchang saw a certain cold evil taste in his calm words.

Zhou Yunchang gasped, he knew that Yuan Hao was serious about discussing this issue with him, so he had no way to call the shots, so he could only quickly inform him of this idea.

Soon, Mao Xinglan looked for Yuan Hao and asked about this matter: "Using a grandfather-level weapon to deal with Zagu, this matter is also up to ......you" Mao Xinglan looked at him seriously: "Do you think this matter is feasible?"

"Rifles can kill, and artillery can kill...... An army with only rifles is an army capable of countering rifles and artillery...... Although it was a bit troublesome, we didn't fight such a battle. Don't forget our first battle of the founding of the country!" Yuan Hao reminded Mao Xinglan with a smile.

"Well, that's not unreasonable. Mao Xinglan nodded understandingly: "But if it doesn't work, you have to have a solid record." He held his chin and thought for a long time, and finally said, "This way, I'll find a chance for you to try your hand...... You can try to improve something first...... If you change it to work, then we will naturally give you more support in this regard. ”

"In that case, I'll wait for your news. Yuan Hao smiled, didn't say anything, turned around and left.

Looking at Yuan Hao's firm steps, Mao Xinglan's heart moved, and he immediately dialed the base below and opened the relevant authority for Yuan Hao.

AFTER YUAN HAO LEARNED THAT HE HAD OBTAINED PERMISSION, HE HURRIEDLY SENT SOMEONE TO TRANSPORT THREE TYPE 30 350MM CALIBER SELF-PROPELLED ROCKET LAUNCHERS BACK TO HIS TRANSFORMATION FACTORY.

After that, for several days, Yuan Hao honestly stayed in the factory to transform his old toys.

IT IS SAID THAT IT IS A TRANSFORMATION, BUT IN FACT, IT DOES NOT USE ANY MEANS, BUT IT IS TO MATCH THE EXISTING SATELLITE DATA WITH DOZENS OF 350MM CALIBER ROCKETS, REPLACE THE RELEVANT COMPUTING CHIPS, INPUT THE LATEST TERRAIN DATA, AND SO ON......

In short, Yuan Hao only changed the arrow body itself as little as possible, and made it more suitable for the current situation through software matching, and replaced the charge in the arrow body medicine room, and filled it with the new gunpowder used by the federal army in active service.

After this series of simple replacements, under the computer simulation provided by the Huaxia military, the newly improved Type 30 350 mm caliber self-propelled rocket launcher has increased its firepower by 150% compared with the original, and has the ability to destroy Zagu.

“...... That's pretty much it. With the power of the 350mm rocket launcher, even if it doesn't hit Zagu directly, as long as it explodes at a certain distance around them, it can pose enough threat to them. Rocket artillery is not guided, perhaps its guidance does not rely on radar, satellites, but on the matching of the terrain.

As long as we make relevant preparations in advance, we can set up the corresponding battlefield. I think these old man's bazookas should give some of the megalomaniacal Jean soldiers a little bit of color. When introducing his urgently modified old man's "cannon" to Mao Xinglan, Yuan Hao said such words with a smile.

This is also a fairly objective analysis. Yuan Hao explained the advantages and disadvantages of rocket artillery very clearly, Mao Xinglan listened and thought in his heart, and suddenly understood how to use such a powerful weapon with great power but low hitting accuracy.

"As long as you don't know what to do, you should still be a little troublesome. Mao Xinglan held her chin and groaned for a while, and finally decided: "Choose a target, let's try!"

The target, in fact, is still a good choice.

The continuous rout of the Federation Army, and the soaring advance of the Jean Army, made these men driving Zagu very confident. Although somewhat cautious, the Guien Army in the Huaxia Theater controlled most of the North China Plain and the Bohai Rim as the Chinese Theater Federation Army retreated, which is said to be the essence of northern China's industry.

However, Jean's army can only do this, although they have Zagu, but this MS is not very many, only 500 MS, with the relevant infantry, officers, technicians and miscellaneous soldiers who accompanied the orbital locomotive landing, the entire generation of Jean in North China has only 40,000 troops.

This was already a heavy army for Jean, but it was nothing to the vast territory of China, and even to the vast North China Plain.

So after Jean expanded in North China, the first thing to do was not to continue to expand his control area, but to arm the existing control area - what is mine is mine, no one can take it, Jean's people are very heroic. Almost at the same time as controlling the key points, they organized the corresponding personnel to produce in the mines and factories.

Jean is located on SIDE3 on the far side of the Moon, which is not a good place for all colonies. Jean is divided into citizens and citizens, citizens are noble and elegant, and have a sense of honor, while citizens bear heavy taxes, which are a group of people who are afraid of haha. After seeing the prosperity of the earth, and secretly hearing that Jean could not occupy this place forever, they did not have so much tenderness for the exploitation of the earth's mines and the production organization of the factory.

Jean needs resources, and Jean's independence needs more resources, so the Federation's resource points, the Federation's factories rotate under Jean's control for eighteen hours in a row - and news of Jean's tyranny has come from all over the country.

Simply speaking of Jean, it's time to start farming!

From an attacker to a defender, Jean's defensive layout in the area of Yanshan and Taihang Mountain also unfolded.

Five hundred Zagu were scattered almost three hundred and set up defensive zones in a direction of thousands of miles. Confident in their own strength, most of them used three, five, and ten Zagu as a garrison area, and cooperated with hundreds or thousands of infantry to deploy defenses. They all believed that with such a force, they would be able to defend against the harassment of the Federation's rout.

They are confident, but the reality is not so simple.

The army in the Huaxia region has retreated, but this retreat is not a retreat. Some soldiers with different tasks remained, lurking in the mountains and reporting the movements of the Jean Army to the headquarters of the Huaxia Theater in the Taihang Mountains.

They set up a defensive line: one Zagu squad with a company to control the small strongholds, two Zagu squads with a battalion in the medium cities, three Zagu squads and one regiment in the large cities - and they began to organize the resumption of production in the mines and factories, forcing the workers to work for long hours.

In just a few days, someone was already dying of exhaustion, and Jean ignored it. He thinks that we earthlings are really like pigs and dogs. After receiving the report from the front, Mao Xinglan immediately convened a combat meeting, and in the star-studded conference room, he sneered and informed his subordinates of the situation.

"Take cities and mines as points and move through roads...... This tactic is very much like the key defense in World War II, and it also has a bit of a cage policy. "It didn't take long for someone to see through that.

"They want to settle down now, so we won't let them settle down. We must let these cosmic people know that the earth is our earth, not a place where they can go wild at will. Mao Xinglan said menacingly.

"So where do we fight?"

"Do we have a way to deal with the other party, Zagu?"

Mao Xinglan wanted to fight, and the generals below were naturally excited, as a soldier, who would like to keep retreating. It turned out that there was no one in the lead, and they were frightened by the monsters of the Jean Army. Now that the troops had regrouped, they thought about it carefully, and it seemed that the terrible Zagu was not so terrible anymore. However, those two problems still need to be solved before the fight.

"Let's fight here......" Mao Xinglan rubbed the map.

"Yi County?" The generals surrounded him: "Yi County controls the Bauhinia Pass, which is very important now to shorten the combat distance. Yi County is in the hands of Jean, and our Taihang base will be threatened...... If we can recapture Yi County, then the protective ring of the entire Taihang Mountain will become even stronger. ”

This is indeed a good goal, and it is also very useful for the side.

But......

What about Zagu? Those green giants aren't that easy to deal with.

"Well, this!" Mao Xinglan groaned for a moment and looked at the back of the conference room, and finally fixed his eyes on Yuan Hao, who was dragged by him to participate in this meeting. He didn't speak, just shook a glance at Yuan Hao, motioning for him to open his mouth to explain the matter.

"I'll leave it to us! I can wipe them out with a large-caliber rocket from fifty kilometers away! The 350mm large-caliber rocket launcher is equipped with a new warhead, which is enough to destroy the 400mm-thick super-hard high-tech steel armor that Zagu is used for. Yuan Hao raised his hole cards flatly.

"What? Do we have this chance to kill Zagu too? Great...... It would be great if it could actually be done. Everyone was very happy to hear that.

"Okay...... Since there is a way to deal with Zagu, let's make tactical arrangements. Mao Xinglan slapped the table and widened her eyes: "Yi Qiu, your Third Infantry Division needs to arrive at the Bauhinia Pass at 3 a.m. on the 20th...... You are the vanguard of this operation, I will give you the full strength to make a single decision, if the Bauhinia Pass is seriously damaged and Zagu is destroyed, you must occupy the pass as soon as possible to open the way for the follow-up mechanized troops. ”

"Understood!" a forty-year-old square-faced man with the rank of brigadier general stood up and replied loudly.

"Then there is the second sequence of tank troops...... "Mao Xinglan arranged their respective tasks in an orderly manner, when that unit would set off and enter the corresponding positions...... That troop was arranged in the first few sequences, and he arranged them all very well.

After this, the sky has become clear. Taihang Mountain, which had been silent for a long time, suddenly made a big move, and countless radio waves flowed up and down Taihang Mountain, looking like a big war was launched. This frightened the North China Front of the Jean Army enough.

"Is the Huaxia Military Region ready to launch a big counterattack? Is it such a big scene?" The commander of the Jean Army was suddenly shocked. He hurriedly ordered his electronic decoding department to analyze the secrets of the other party's telecommunication signals, but in the end he got a disappointing situation: "Potatoes, potatoes, tomatoes, what the hell are they?"

Jean Jun didn't understand, so he was naturally nervous half to death.
