The maintenance car quickly repaired the base car that was working all night, and according to the agreement, he took Yi Xiaofan back the same way.

The canyon is not long, but the stone mountains on both sides are more than 200 meters high, showing a fiery red landform. Some drought-tolerant plants can be seen in the canyon, such as the three-storey cactus.

It took the troops more than ten minutes to pass through the canyon, and at this time, a path formed by long-term crushing appeared in front of Yi Xiaofan's eyes.

"There's a way!"

If there is a road, it means that people often pass by here, and there are also signs of population activity, so it seems that this trip was not in vain.

"The base of the Black Eagle Empire is about three kilometers down this road." Ye Wuxiu pointed to the main road and said.

"Thank you! Please, see you again in the future. ”

Yi Xiaofan turned around and said that he was going to attack the Black Eagle Empire base, and it was difficult for him to operate it if there were outsiders there.

"Okay! Dude withdrew first, thank you today! ”

Ye Wuxiu entered the canyon again with the base car, and it seemed that he was still planning to go south.

The troops marched three kilometers to the north, and sure enough, they saw a base, compared to the rebels that Yi Xiaofan had dealt with before, the base of the Black Eagle Empire was a level higher. Yi Xiaofan felt close and found that a tank factory had been built in the base, and more than twenty Grizzly tanks were lined up in the open space outside the tank factory at one time. Moreover, on the periphery of the base, Yi Xiaofan also found steel-concrete walls, which were four meters high to protect each building and increase the difficulty of the attack.

At each of the three entrances to the base, the Black Hawk Empire had built four machine-gun bunkers, in addition to an anti-aircraft turret behind the walls at each of the four corners of the base.

"This defense is simply against the sky!"

In addition to the twenty Grizzly Bear tanks and these defensive buildings, Yi Xiaofan found a mine not far behind the base, and the piles in this mine were no longer golden ores, but colorful colored ores!

There is information about colored ore in the official website, and the gold content of mining is twice that of ordinary ore, which means that the super-space-time mining vehicle can get 1,000 funds for collecting a car, which is equivalent to only 2.5 hours to get 500 capital ore, which is half the time compared to ordinary mines.

At this time, there are two mining trucks operating, Yi Xiaofan's heart is itching at the moment, if this mine is occupied, he will not worry about the source of funds in the short term.

"Assault!"

In the face of such a base with extremely strong defensive capabilities, without the addition of new troops, any combat plan will be futile, and it can only be fought in a hard-fought war of attrition.

"Attack!"

After Yi Xiaofan arranged the troops on the three-dimensional map, he launched an attack on the base, and his own troops would act according to the attack route and target formulated by Yi Xiaofan.

As soon as the five Grizzly tanks appeared near the base, the Black Hawk Empire alarm suddenly sounded, and the Grizzly tanks that had just come off the assembly line near the tank factory rushed over.

Yi Xiaofan let the Grizzly Bear tank act as a meat shield, and the three armed assault vehicles attacked with all their might. The power of the four machine-gun bunkers was comparable to that of fifty Allied soldiers, and after half a minute of firefighting, his Grizzly tanks exploded one after another, leaving only two tanks after taking one machine-gun bunker.

In order to increase the output, Yi Xiaofan asked the engineer to leave the infantry chariot, and three multi-purpose infantry chariots also joined the attack. Two minutes later, Yi Xiaofan's troops were completely wiped out under the cluster attack of the bunkers and the opponent's twenty tanks, but three of the bunkers in the Black Eagle Empire's base were eliminated by it.

Yi Xiaofan retreated to the periphery to transfer out the overview, and spent 11,200 points to build sixteen Grizzly Bear tanks at one time and let them go here immediately.

An hour and a half later, sixteen brand-new Grizzly Bear tanks emerged from the canyon and headed straight for the Black Hawk Empire base. Although the Grizzly Bear tank is slow, its lethality against heavy armor is much higher than that of armed assault vehicles.

Yi Xiaofan ordered the Grizzly Bear Tank to set fire to the remaining machine gun bunker, and finally took the main gate after losing two tanks, and the Grizzly Bear tanks on both sides finally pinched each other face to face.

Due to the weakness of the troops, coupled with the consumption of two anti-aircraft missiles, Yi Xiaofan's 14 tanks were all wiped out again after replacing the 9 tanks of the Black Hawk Empire, but fortunately, the kill reward balanced Yi Xiaofan's battle loss ratio, and more than 3,000 funds could be regarded as a 9-9 tie with the enemy.

In another two hours, sixteen Grizzly Tanks and three mining vehicles made a comeback, and this time in order to reduce the losses of Grizzly Tanks, Yi Xiaofan sent mining vehicles. The Mining Cart is added as a meat shield and can reduce the damage of the Grizzly Tank.

The three mining trucks marched into the base entrance in unison, instantly attracting all enemy firepower, and the Grizzly Tanks followed were a fierce bombardment of the Black Hawk Empire's tank troops.

At this point, the situation seems to be reversed, and the three Chrono Mining Vehicles are like three machine-gun bunkers with no attack capabilities, but more than double their HP. Although the armor type is only medium armor, it is enough for the Black Eagle Empire to fight for half a day.

Bang bang bang!!

At the moment when the three mining vehicles exploded, Yi Xiaofan's Grizzly Bear tank had already destroyed the enemy tank force and began to attack the anti-aircraft missiles on both sides. At this time, Yi Xiaofan finally breathed a sigh of relief, although he suffered heavy losses in this battle, as long as he could control the mine, everything was worth it.

After cleaning up the two anti-aircraft missiles, Yi Xiaofan then knocked out the front end of the tank factory and barracks, and before dark, Yi Xiaofan let the troops withdraw to the entrance. He now has just over 9,000 funds left, which is not enough to build another fleet of tanks, and he must be careful at this time.

After thinking about it, Yi Xiaofan organized a maintenance vehicle and came over with a newly built mining vehicle. Without tank firepower, coupled with the attraction of firepower from minecarts, Yi Xiaofan's attack on the machine gun bunkers on the left and right sides was much smoother. With the help of the repair vehicle and timely repairs, he managed to take out all the defenses of the base at the cost of six Grizzly tanks.

destroyed all the buildings of the base overnight, and Yi Xiaofan finally recovered more than 7,000 funds, but he did not demolish the wall. This mine is too far away from the main base, and if someone wants to attack the mine, he can't immediately support it, so he plans to open a sub-base here after the upgrade.

After knocking out the Black Eagle Empire mining cart parked in the mine, Yi Xiaofan began to arrange for the main base to come out of the mining truck to collect here, but the distance was sixty or seventy kilometers apart, and it took two hours for the mining truck to come over, so in addition to the one mine truck left on the side of the main base, he arranged for four other vehicles to come here to collect. In this way, even if the ore stored here is exhausted, the two mines can provide 3,000 points of capital per hour.

After doing this, when Yi Xiaofan was about to go offline to sleep, he suddenly remembered that he hadn't added an excellent friend, so he called up the friend menu and searched for the Eight Immortals Table to add him to the friend list. As soon as he submitted the friend application, Excellence actually agreed in seconds, and sent a voice request.

"Table, what are you doing here?"

"Don't mention it, the ore refinery was built just now, and now it's all over the world looking for ore." Yi Xiaofan has a bug, and he can't experience the torment of waiting for the construction to be completed, but it is indeed very troublesome to find a mine, although his development speed is shocking, he is not worried about the mine this afternoon.

"It's hard to find a mine, it took me an afternoon to find a mine, and there are still heavy troops from the Black Eagle Empire, so I don't have a chance to start at all."

"But no, I also encountered two mines, either the rebels or the Black Eagle Empire, and it is very difficult to find natural ownerless mines."

Yi Xiaofan chatted for a few sentences and returned to the topic and said: "At noon today, I want to ask you, how much is a diamond black market now?" ”

"Brother! Do you know how hot Backfire is right now? According to preliminary official statistics, the number of players whose base vehicles were destroyed after the launch of the server today reached 11 million. The diamonds on the major black market three-party trading websites have been speculated to a maximum of 5,000 yuan, and they are definitely priceless! ”

"Five thousand!" Yi Xiaofan was taken aback, this was enough to pay his rent for two months, and at the same time, he thought of letting that player leave this afternoon, and he couldn't help but regret itchy, and the five thousand yuan in his hand actually flew away.

"Of course, this price will definitely fall in the future, but in two weeks, the price of diamonds will definitely not come down. After two weeks, the player should have the initial ability to attack, and if multiple players join forces to attack the system forces or other players, the diamond should be easy to get their hands on. ”

If you are excellent, you are very market acumen, and Yi Xiaofan feels that he should take advantage of the inflated price of diamonds in the past two weeks to set up some money to improve the living environment.
