Although a wave of assaults failed to kill the Elder of the Deep Sea Fishmen, Hu Siming's results were still quite impressive. The low-level fishmen killed several of them, and the fishmen thugs and blood witches also killed one each, which was equivalent to the loss of a third of the backbone of the fishman tribe.

If it weren't for the decisiveness of the Deep Sea Fishman Elder's retreat, Hu Siming would have been able to leave two more.

However, the previous victory was only a small victory. The Elder of the Deep Sea Fishmen is still there, and the Fishmen's dragon turtles, blood witches, and fish-people thugs are still there. If it is a field battle, Hu Siming's current strength can already have the upper hand. But after they retreated to the reef base, their shape became the same as before. Again, one side has the advantage in troops, but the other side has the advantage of bases and towers. If you attack it, it's hard to say the result.

The Fish-Man's Guardian Tower, which has slightly lower durability than the Arrow Tower, but has a higher attack power. The four Guardian Towers are enough to wipe out Hu Siming's superiority in strength. What's more, there are still many Mugol slaves in the fish-man tribe. Although they were only a little stronger than the untransformed Terran farmers, they could not hold up the number of them, at least ten.

If one of them is not done well, if he rushes in, Hu Siming will be directly damaged under the defense tower like the first and second waves of fish-man troops.

He didn't want to take that risk.

After regrouping his troops and letting the priest heal those units that were not up to their health, Hu Siming took them around the reef base in a proud circle. But unfortunately, the Elder of the Deep Sea Fishmen had no plans to come out. It calmly led its troops behind the Guardian Tower, while amassing resources to train new Fish-Man Thugs and Mugol Priests.

The huge dragon turtle was also placed in front of the four defense towers.

If Hu Siming wants to storm the defense tower, he must first encounter this huge dragon turtle!

Realizing that the battle could not be ended in a short time, Hu Siming led his troops to retreat a little back, ready for a protracted battle. Anyway, during his expedition, the double mines in the base were still operating. During this time, a lot of resources have been accumulated. He wasn't worried that the Fish-Man Tribe would be able to turn around, but mainly worried about how to break through the Fish-Man Tribe's defenses.

The current situation is like the highland in the compulsory course.

The hero on one side has already taken control of the situation and pressed the opponent on the high ground, but he has never been able to attack. If you can't break the road, even if you have an advantage, you can't turn it into a victory.

Is there any way to do it?

Hu Siming looked at the shallow sea a hundred meters away, and his brain spun rapidly. Perhaps, I can go back and hire a warship with goblin artillery?

The attack range of the battleship is 100 miles longer than that of the defense tower, which is almost enough to suppress the range. It's just that the location of the base chosen by the fish-man tribe is excellent, and there are a large number of coral reefs in the shallow sea. The human troops themselves have to endure a 20% deceleration when advancing in the shallow sea, and with such a complex terrain, it is difficult for the troops to deploy, even if they really use the warship to suppress and bypass the frontal landing in the shallow sea, they may not have much advantage.

After all, there is no limit to the speed of a fishman in shallow water.

In this case, there is only one path you can choose, and that is to continue to expand your army, and focus on training units with siege capabilities!

The giant turtles and dragon turtles of the fish-man tribe have amazing defensive capabilities, and the attack type is also siege, which is designed to destroy buildings. In the setting of the battlefield, the Terrans who can fight against them naturally also have special siege units. Previously, because there were knights and spellbreakers, Hu Siming felt that there was no need to train such a bulky thing, so he didn't make it. But now that the fish-man turtle can't shrink, he can only think about attacking.

After giving the order remotely, a logging farmer at the main base stopped collecting and began to build a workshop!

The workshop, according to the background set in the rehearsal battle, is a new building obtained by the Terrans after fusing some of the goblin technology. This can train the Terran's most resistant and sturdy mechanical unit, the Steam Tank.

【Steam Tank】

A high-level Terran class and a mechanical siege unit.

Durability is 950 points, Attack damage is 48-57 (siege damage), Armor is 6 points, Base Movement Speed is 240 points, and it cannot restore durability on its own. Has the passive trait: Magic Armor Lv1.

Magic Armor Lv1: Reduces physical damage taken by 20%.

With a whopping 950 durability and 6 armor, the Steam Tank is a more perverted meat shield than the Knight. The Magic Armor trait reduces physical damage taken by 20%. Even the dragon turtle that has just entered the fish-man clan in front of it has the power to fight. Also, its attack type is Siege, which can deal excess damage to the Fish-Man Guardian Tower. The only drawback is that it is expensive, slow-moving, and unable to recover on its own.

It seems that this is the most inferior point of the dragon tortoise, but it may not be the case in actual combat.

The Dragon Turtle is a magical beast with a good life recovery ability. After a battle, you only need to rest for a few minutes to recover a lot of health. Steam tanks, on the other hand, cannot, and no matter how long they are broken, they will not get better on their own. However, the characteristics of the mechanical unit allow it to be repaired. As long as Hu Siming is willing to let the peasants repair the steam tank under attack at any cost, he can make this bulky machine exert stronger combat power.

As long as two, no, in order to ensure a success, Hu Siming decided to train three steam tanks, and then take the farmers in the main base to defeat the fish-people in one wave!

Because the workshop is also a high-level functional building, the speed of construction is a little slow. Hu Siming didn't want to give the fishman too much time to breathe, so he transferred two more farmers and began to cultivate together.

Nearly twice as fast as construction!

Although this means consuming a third more resources, Hu Simin has a double mine. Rich!

If it weren't for the three of them to repair together, they would have basically approached the fastest construction speed, and he would never mind pulling in two more farmers. When a new fish-man mob was added to the fish-man tribe's side, the workshop next to Hu Simin's main base sounded the steam whistle of Ulala, and it was officially put into use.

Hu Siming didn't say a word, immediately invested resources, and joined the training sequence of three steam tanks in a company.

Before the arrival of the steam tank, Hu Siming did not plan to engage the fish-men again. After pulling a safe enough distance, he hesitated and personally took the boat back to the main base, ready to pick them up. There is no way to do it, the Steam Tank only moves at a speed of 240 points, which is slower than the Dragon Turtle. There was no acceleration aura to destroy the horn of Miè, and they ran to the goblin dock on their own, I don't know how long it would take.

Moreover, Hu Siming is also ready to take this opportunity to return to the base to buy something in the mysterious treasure room.

A wave with a steam tank, which will undoubtedly be his final blow. It would be a waste to keep the remaining resources, and he wanted to procure as much as possible to increase his chances of winning the battle. If you can defeat the Fish-Man Tribe with minimal losses, maybe the final battle total score can be even higher.

The mysterious treasure room, held by four chains and suspended above the ground, has a lot of good things. Among them, the mini primary defensive arrow tower is a good item. Because it is a ready-made tower base, the speed of forming after putting it down is faster than the speed of taking farmers to repair it first. When the steam tank attracts the attention of the fishman, Hu Siming can put down three defensive arrow towers in a row and directly set up the defense line to the door of the fishman's house. In addition, a recovery scroll that restores 200 HP is also essential. Halfway through the fight, he realized that the priest's treatment was not enough, so he immediately stepped back and recovered for a while, and then continued to fight.

The three primary arrow towers, plus a recovery scroll, consumed all the resources collected by Hu Siming during this time.

However, as long as it can add even a 10% chance of victory to the final general attack, it will be worth it!

At this time, accompanied by the sudden sound of a steam tank and a thick white vapor, the first steam tank ran out of the workshop. Its shape is similar to that of a real-world tank, but it is much smaller. Of course, in comparison, this four-meter-long, thousand-pound tracked tank is still a behemoth that can compete with the dragon tortoise. Because the ground near the base was just ordinary flat land, after the steam tank was driven, it left a long track trail on the ground.

However, under the influence of the laws of the academy, these traces only existed for more than ten seconds before gradually calming down and disappearing.

After waiting a little anxiously for two minutes, Hu Simin gathered all the siege troops and set off with three steam tanks and at least six peasants!

Accelerated by the Horn of Destruction, the Steam Tank sped up a lot, crossed the island with a roar, and was carried by a sailboat hired by Hu Siming, officially joining the battle sequence on the front line. And by this time, the Fish-Man Tribe had added another Fish-Man Thug and Mugor Priest.

Their strength has largely recovered to the situation before the war.

If it weren't for the resources collected by a single mine that limited the speed of development, maybe when Hu Siming arrived with a steam tank, he would find that the strength of the fish-people would become stronger. Fortunately, this scene did not appear, and Hu Siming, who had almost suppressed all his strength, still maintained a sufficient advantage over the fishmen.

"Kill, kill, kill!"

As all the troops pressed again, Hu Siming's raised right hand struggled down and launched the final general attack!

All the Terran forces, including infantry, musketeers, witches and witches, and even the peasants brought by Hu Siming, moved together, led by three huge steam tanks, and rushed head-on into the defense line of the reef base with the momentum of stepping on a flat foot. Almost at 700 range, the Fish-Man Tribe's Guardian Tower was resurrected, spitting water arrows at the Steam Tank.

However, it doesn't hurt or itch!

With 950 durability, 6 armor, and passive damage reduction, the Steam Tank has incredible defense. The three tanks easily withstood two salvos, rushed to the bottom of the tower, and began to attack with impunity.

Musketeers and knights swarmed up, boosted by the priest's psychic fire, to assist the steam tanks in their demolition of buildings
