After another three days of rapid marching, Chen Tu and his group finally arrived at their destination, the Ferghana Mountains. The Fergana region is rich in mineral resources and is an important industrial region in the north of the country, where many special metals are produced.

Luo Fei is ready to build a number of interconnected defensive bunkers here to deal with Tianyu's flexible mechanized troops, as the head of the Luo family, Luo Fei also has a certain understanding of the Tianyu Empire, the original population of the Tianyu Empire is only fifteen million, but in the past thirty years of external expansion, they have annexed the United Kingdom of Luluabao, the Kingdom of Luai, and the population of the Kaya Empire has soared to 80 million, and with it, the military strength of the Tianyu Empire has increased.

The Emperor of the Tianyu Empire, Bel Haast, was a great man, and except for the United Kingdom of Luluaburg, the other three countries were conquered under the leadership of Bell. The purpose of the Tianyu Empire is also very clear, it has annexed the Moon Mo Kingdom, and there is no rival around the Tianyu Empire. From this point of view, the melee of the Yuemo Kingdom family is not useless, at least a group of powerful combat troops have been retained.

Luo Fei connected Luo Ning's communication and prepared to tell Luo Ning about the defense construction plan.

"Father, can you ......?"

"Are you kidding you?" Before Luo Ning finished complaining, Luo Fei directly interrupted him. His son Luo Ning knows best, he has no ability at all, and he still wants to take on big responsibilities, that is, he is a little like Luo Fei, that is, he is not afraid of death. "These defensive bunkers must be completed within a week, otherwise military law will deal with them." Luo Fei knew that Luo Ning would not listen to him if he didn't say something cruel.

Luo Ning saw that there was no room for bargaining, so he had no choice but to agree.

The 9th Engineer Corps was tasked with building fifty defensive bunkers, each three kilometers long, stretching from the foot of the Ferghana Mountains to the halfway point of the mountain.

The house group happened to be assigned to build a bunker on a mountain corridor, all the things were made of local materials, the Luo family also distributed some hand saws, shovels and other tools, Chen Tu got the defense construction drawings, the fortifications are very simple, every 500 meters to build a watchtower, the watchtower must be six rats high, and the bunker only needs to be higher than two rats. Chen Tu quickly assigned the task.

Chen Tu put Randy in charge of logging and Chen Tu in charge of building, after all, Chen Tu was more experienced than them in this regard.

On the first night in the Fergana Mountains, all the people in the house group were not really asleep, and the wingmen of the Tianyu Empire flew overhead from time to time, and the sound of air force fire was heard in the sky. In the middle of the night, the sound of artillery fire on this side continued to sound, and everyone was frightened into lying in a part of the bunker that had just been built during the day.

The Tianyu Empire had no intention of attacking, their purpose was simple, it was to harass on a small scale and exhaust the army of the Moon Mo Kingdom. Chen Tu, who knew the situation, found a few people on duty in the second half of the night, and let everyone sleep, after all, he would continue to build fortifications tomorrow.

Although Luo Ning was not interested in building fortifications, he still had to do routine inspections. Of course, Chen Tu was not lazy, so the inspection was completed quickly.

Because it was mountainous and there was no machinery, it was difficult to build fortifications. The men of the Ninth Engineer Corps all felt that it was dark at dawn, and Chen Tu was no exception, and he dug stones with everyone to build fortifications, and his muscles were sore all over his body for two days.

The conflict at night has also become more and more intense, and according to Yuemo's reconnaissance report, the Tianyu Empire has gathered 300,000 elite troops here. There will also be a tentative attack from the Tianyu Empire at night, but they are all blocked by Luo Fei.

At noon on the seventh day, the fortification that Chen Tu was in charge of was finally completed, and all the rats in the house group were cheering. It's finally time to take a break.

Although the fighters in the sky whizz past from time to time, most of them are from the Moon Mo Country, and the two sides are now attacking on a large scale, and there is not much contact.

It was the adjutant of the engineering unit who came to inspect the fortifications, and the adjutant told Chen Tu that the Luo family army will be stationed here tomorrow, and we will have a day to rest, and then, we will build a larger trench in the rear.

What else can Chen Tu say? I want to go home? Chen Tu said that it is our responsibility to defend Yuemo and be loyal to the royal family, and it is our honor to be able to contribute.

The adjutant said that I have experienced a military career since I was a child, and I am also concerned about Yuemo, and now that the country is in trouble, it is a good time for us to make a big move.

The adjutant is really a hero in the army, a model for my generation, and the adjutant is expected to study hard, muster up our ambitions, and fight Tianyu to the end. Chen Tukou is like a river, touting the adjutant, and this adjutant also looks useful.

After inspecting the three kilometers, Chen Tu is already the eldest brother, the eldest brother's call, Chen Tu said that he must go to the eldest brother to drink two drinks if he has the opportunity, and the adjutant said with a smile, junior brother, your eldest brother, my past can still tell you another table. Chen Tu almost bid farewell to the adjutant with tears, Chen Tuxin said, it turned out that this sycophant was unconsciously filmed.

After the acceptance is completed, Chen Tu will take the acceptance order to the logistics office to gather, and after a day of rest there, the second phase of the operation will begin.

However, this will not be able to be started until tomorrow, and the Luo family army will not be able to stay in the fortifications, and the logistics department will not be able to vacate space at all. After all, Tianyu came very suddenly, and the Luo family army was also transferred suddenly, but it also took time for all kinds of supplies to be transferred.

As usual, Chen Tu let everyone have a good rest, and only arranged for 20 rats to be on duty to keep vigil. In the evening, shells explode from time to time, which is normal, after all, it was like this for the past few days.

The Zhao family and the Luo family only arranged 10,000 infantry each at the forefront of the fortifications as a vigilance. After all, there are no fortifications, so pulling the army into the radiation range of the enemy's artillery fire and being harassed by the enemy is undoubtedly reducing the combat effectiveness.

It was a little late in the night, and the front reported to the War Department that a large number of scouts had been found in Tianyu, but instead of hiding, they were releasing cold guns. The front-line troops asked if they wanted to return fire.

The Luo family exchanged views with the head of the Zhao family, and always believed that this was nothing more than harassment, and this kind of harassment would not be broken when the Tianyu Empire did not mobilize enough troops to come over. Because according to the reconnaissance report, Tianyu only mobilized 300,000 troops, in addition, according to the news from the spies in the Tianyu Empire, it has been raining in the main administrative areas of the Tianyu Empire recently, which has brought trouble with the transfer of materials.

"Our primary goal is to monitor the movements of the Tianyu army, and we don't have to pay attention to their harassment." Luo Fei directly gave orders to the troops stationed on the front line. Zhao Liang, the head of the Zhao family, brought the same words to his own army.

Maybe the Tianyu Empire also felt that it was useless to release cold cannons, so it only symbolically fired a few cannons in the first half of the night.

At this time, the night was late, and even the people on duty were tired, and wars often began at this time.
