077 Base Defense 1! ( Fourth update)

Ten days flew by. During these ten days, Ya Gan and others finally broke through their limits under the continuous supply of materials from the federal government. Among them, the ones whose strength has improved the most are Yagan and Luo Zheng. Although they are all fourth-order, they have broken through the fifth-order barrier with others with sufficient crystal drills and material assistance and become real sixth-order strongmen.

Until this moment, the advantages of the mercenaries in the magic training field have also been completely demonstrated. At the low and middle levels, as long as the mercenaries have enough crystal drills, their strength can be improved at a miraculous speed. However, the only regret is that it cost an unimaginable price to break through the sixth level in a short time, which not only consumes a whole five million crystal diamond reserves and a large amount of materials of the Federation, but also squandered five million crystal drills and a group of props worth three million yuan in the underground battle. To be honest, if these crystal diamonds and props are used rationally, it is not impossible for others to even upgrade to the seventh level. However, now that time is limited, they can only forcibly improve their strength in this way.

Great effort is equal to great harvest, which is the eternal truth in the training ground of gods and demons. Exactly 13 million crystal diamonds have been exchanged for the leap of Zhou Feng's team. Among them, Zeng Yike, Murong Yu and Zeng Rou not only raised their strength to the sixth level, but also strengthened their bloodline to the Golden Titan bloodline, high-level shadow elf bloodline and natural druid bloodline respectively. After the promotion, Zeng Yike's strength has not only been greatly improved, but also the lightning support special effects are also urgent for the Thunder Thunderbolt special effects. Any enemy attacked by Zeng Yike or by Zeng Yike will be attacked by thunder. The strength of the thunder attack is related to Zeng Yike's strength, and there is a certain chance to give the enemy a paralysis effect.

After Murong Yu's bloodline was promoted to the high-level shadow elf bloodline, it also had a huge qualitative change. First of all, the passive special effect of her shadow invisibility has become an active special effect of lostness. Once it is used, it can enter the stealth state under any circumstances, and more importantly, the priority of this stealth state is extremely high. Some detection magic props or skills can't be detected. And lost and hidden can also increase Murong Yu's movement speed and attack speed by 50% in the stealth state, making her a real killer.

Zeng Rou's natural Druid bloodline is slightly different. The natural Druid bloodline not only improves Zeng Rou's ability, but also gives Zeng Rou a special deformation effect, so that she can be transformed into three forms: cheetah form, eagle form and giant bear form. Among them, the cheetah form can have stealth ability, while the eagle form can make Zeng Rou have the ability to fly. As for the giant bear form, it can improve Zeng Rou's strength and defense. With these three forms of body protection, Zeng Rou's survivability on the battlefield has undoubtedly been greatly improved.

As for the feeling, the bloodline of Zeng Yurou and Luo Zheng has not changed, because the bloodline of the three of them cannot be promoted. If they want to change the bloodline, they need to reset the bloodline, so it is impossible and there is no need to improve their bloodline for the time being. The remaining Lania finally exchanged for pure blood potion and turned herself into a pure blood clan, thus getting a series of blood clan talents, which greatly improved her strength.

However, although the strength has been greatly improved, the mood of Ya Gan and others is not too excited. After all, most of the huge wealth that could have allowed them reach the peak of the sixth level or even break through the seventh level has been wasted by them. In other way, everyone will feel distressed and pity. And this opportunity can be encountered but not sought. This time, they have exhausted the federal reserve supplies. If they want it again, they can only think about the federal war reserve materials. However, even bold people can't help but put away this idea. You should know that crystal drills are also extremely cherished wealth for the Federation, and it is an excellent energy source in addition to improving the strength of soldiers. Even the proton generator that supports the defense system of the three major bases uses the crystal drill as the energy body, so this crystal drill must not be moved in any case.

Another piece of news that makes people feel heavy is that the main force of the Zerg has gradually been under the city in these ten days, and the three human shelters of Flame, Hanbing and Thunder have been completely blocked by a huge encirclement. At this moment, the three shelters are completely occupied by the Zerg, whether in heaven or underground or underground, and as soon as the time comes, the Zerg will immediately launch a general attack and flock to them.

After learning that Yagan and others had successfully broken through, Kurt Kings and others were surprised and immediately gave them an order to station in groups to guard the three fortresses of Thunder, Flame and Ice. According to the return of the remaining clone soldiers in front, they can also stop Zerg reinforcements from all over the country for about ten days, plus the time on the road is only 20 days. This is the most critical 20 days. They must put as much pressure on the Zerg army as possible during these 20 days, so that they can continuously send the army to the three major bases. The more Zergs are sent from the mother's nest, the more empty the strength of the mother's nest will be, and the greater the success rate of their actions will be.

After receiving Kurt Kings' order, Ya Sen and others were also divided into three groups, stationed in three shelters. Among them, Rania, Zeng Yurou and Zeng Yi were stationed in the Flame Fortress, while Ya Gan and Murong Yu were stationed in the Cold Fortress. As for the Thunder Fortress, Zeng Rou and Luo Zheng led a group of mutants and strong men. Because although the defense power of the Thunder Fortress is the strongest, the Zerg who besieged the Thunder Fortress at the same time are also several times that of the other two major fortresses. It seems that the brain worms have long known the location of the human commander, so they mainly attack the city.

With the passage of time, the Zerg army finally launched a full-scale attack on the third day of Yagan and others breaking the barrier. Suddenly, the overwhelming Zergs, like the darkness covering the sky and the land, rushed towards the three bases with indescribable horror.

——————

The ice fortress is the strongest defense and the weakest counterattack ability among the three human bases. The ice defense system of the fortress can turn the fortress within 10,000 meters into a bitter cold place. The closer it is to the city wall, the lower the temperature will be. And when the enemy enters within a thousand meters of the city wall, what awaits them is an absolute zero that can freeze steel into pieces - minus 273.15℃.

Moreover, the absolute zero of the ice fortress is different from the absolute zero in the general sense. The science and technology of the wasteland world has reached the extent that it can almost use technology to create magic elements. This low temperature of -273.15℃ can not only freeze the other party's body, but also has a magic effect of "extinguishing". Once it is completely frozen, the frozen object will soon be re-degraded into the simplest cold air, and even the scum will not be left. And the cold air turned into this corpse will once again become the supporting energy of the ice defense system. It is extremely difficult to break through such a cycle.

However, although the ice defense system of the ice fortress is strong, it still can't stop the hundreds of millions of Zerg troops. Because even if the magic special effects of [Destroy] can turn those Zerg into flying ash, the speed of their destruction can't be compared with the Flame Fortress and the Thunder Fortress anyway. Under the continuous crazy impact of the Zerg, the ice fortress was soon surrounded by different forms of ice sculptures. The other Zergs stepped on the ice sculptures made by their companions and rushed towards the walls of the ice fortress like sea tides.

The first wave of swiftworms and flying insects rushed to the wall. Although their speed has been greatly reduced under the erosion of the cold, their number is too much. Soon countless Zerg climbed up the wall and began to wave sharp claws at the clone soldiers on the wall. However, what is more troublesome is that the temperature on the wall has returned to normal, so once these insects rush on the wall, they can quickly get rid of the slow effect of the cold and play a terrible lethal effect.

"Damn bug..."

Looking at the Zerg who rushed up to the city wall, a cold murder flashed in his eyes. Although the strength of these veloci and flying insects is low, the number is too much. Although the ice fortress has fired a large number of incendiary bombs and high-explosive bombs, and caused nearly tens of millions of terrible casualties to the Zerg. But these tens of millions of Zerg corpses were quickly covered and devoured by more Zerg, and then became the energy in these Zerg's bodies, supporting them to resist the cold attack, so as to rush up the wall at a faster speed.

Devour the same kind, and use the corpses of the same kind as energy to temporarily improve your defense against external attacks. This attribute is not terrible for other Zerg, but it has become the most terrible talent ability for a large number of Zerg such as Veloci and Flying Bug. This is also the real horror of the Zerg cannon fodder tactics. The more you kill, the stronger these bugs will be until you kill all the bugs, or you are destroyed by the bugs.

"Start secondary defense measures!"

Just as more and more Zerg rushed up to the wall, and the endless ice sculptures also besieged the wall, the feeling that had obtained the command of the ice fortress also opened the intelligent brain controller given by Kurt Kings, and connected the intelligent brain to issue voice commands. As his voice fell, an extremely chill suddenly shot out from around the wall. At the same time, the originally illusory cold air suddenly condensed and turned into a huge ice sheet to cover the whole area of 10,000 meters.

Although the ice defense system does not have the ability to fight back, it is not so easy to break it.

"Everyone's speed to empty the Zerg around the base!"

Looking at the large number of Zergs separated by the ice cover around the fortress, a sarcastic smile also appeared on his cold face. Then he raised the miniature electromagnetic pulse gun in his hand and aimed at the Zerg who were still hitting the city wall and pulled the trigger, so with the spark of blue flames, a large number of Zerg were also affected by these small The energy-chemical bullet was directly torn into pieces. Then the laser beam penetrated one Zerg after another, and the Zerg, who lost their vitality, could not resist the erosion of cold air. In the blink of an eye, they were frozen into pieces and then disappeared.

The best way to deal with the Zerg cannon fodder tactics is to completely destroy them and don't even leave the corpses!

hong hong hong hong!

However, just as Yagan and others were frantically cleaning up the Zerg in the ice sheet, bursts of violent roars suddenly sounded from the sky. Then only countless bone spurs, molten pulp and venom bombarded the huge ice sheet like a storm, bombarding the ice sheet one pit after another. At the same time, a large number of melee worms such as vecic worms, flying insects and even golden beetles are constantly gnawing and attacking around the ice sheet. Although they were soon frozen into ice sculptures by the absolute low temperature attached to the ice sheet, there were still endless cracks in the ice sheet under the crazy impact of the Zerg.

"What crazy guys..."

Looking at the remote Zergs in the distance who are constantly spraying thorns, molten slurry and venom, and the swift insects that have to dig out a piece of broken ice for their lives, their eyes have become cold again.

The ice base with the strongest defense has been under so much pressure. It can be imagined that the situation of the Flame Base and the Thunder Base will not be much better.

Support for 20 days... This is not a very easy task.
