The fire was raging, but it was not weakened in the slightest on the surface of the lake, as if even the lake water was burning together, and under the influence of the explosion etching, the explosion was even more violent, and the flames splashed everywhere.

For Zhang Sheng, who has won several key victories with fire, this scene in front of him is the most beautiful picture in the world!

[System - If you successfully use fire attack on the battlefield, you will be rewarded with +5 Intelligence.] 】

One by one, the demon army that was directly ignited, or ignited by the flame splash, let out a terrible scream, and jumped into the lake one after another, but the effect was not good, because they were either contaminated with fire oil or poisonous flame bombs.

The attack of the fireship was not concentrated in one point, but scattered and impacted multiple areas, and the fire was spreading at the moment, but the pontoon bridge was not directly burned, and the Dao Dao spirit pattern appeared, emitting a dense spiritual light, and it was not surprising that the wooden rows connected into the pontoon bridge were engraved with protective etchings.

On regular battlefields, psionic technology is very common, and the relationship between a novice lord and a rebel or bandit can only be regarded as a game at best.

Protective etching is for objects rather than living creatures, and is used for city defenses, field fortifications, camps, ...... It is mainly aimed at the protection of important building facilities. In this high-martial world, even mountains can be flattened, let alone city walls, and if the city you have worked so hard to manage is not protected, it may not take less than a month to be demolished, and the defense of the city cannot be fought at all.

The same is true of warships, which can be torn to shreds by the aftermath of a great battle between the two sides without protection. For lords, the importance of protective etching is self-evident!

In addition to the ability of the psionic researcher, the effect of protective etching also depends on the scale of the etching, and its essence is to share the damage, and the more connected spirit pattern groups, the stronger the protection effect.

But there is no absolute insoluble solution, and since the psionic researcher has researched the protective etching, he will naturally study the corresponding restraint means.

Fire oil cannot be extinguished with water when it burns violently, but it can be quickly disposed of whether it is covered with sand or directly attacked by a general.

The flotilla advanced and the catapults placed on the building ships were also etched to strengthen the power of the throwing rod, which was equivalent to increasing the maximum range, but due to the limitations of time and materials, it was not possible to configure more powerful and suitable ammunition for throwing, so it could only continue to use poison and flame shells. It's just that the accuracy is still worrying, after all, the catapult is only a rudimentary weapon of war, and many fundamental problems cannot be changed by etching.

I regret it, I have to buy the [Liuyan Burst Crossbow] that Ren Changsheng sold at the beginning, and at most two rounds can open a gap in the pontoon. But who would have thought that they would be drawn into the war so early?

At this time, a demon general on the pontoon bridge jumped high and flew a poisonous flame bullet, bent his bow and arrows in the process of falling, and the arrows flew towards Yan Guo who was standing with Qin Liangyu under the light of the fire, who made her dress beautifully! In the case that the commander of the enemy army cannot be determined, whoever is the most coquettish in the enemy will strike first, this is the consensus!

Zhang Sheng also opened his bow, this was the first time he encountered an enemy general on the battlefield to greet him with a bow and arrow, which was a good opportunity for him to brush up on the title task. But......

Failed!

The two arrows did not intersect in the air, and each flew to the opposite side, and Yan Guo slapped away the oncoming arrows with a bang.

Zhang Sheng silently put down the longbow, this is normal, there are few people in the entire classical history who can play the fancy operation of arrows and arrows, not to mention that it is still night, and the fire is dazzling. Besides, no one knew his true purpose, in fact, he just wanted to shoot a calibration so that the bow and arrow regiment could fire a salvo.

"Burst arrow ready, forty-degree projectile!"

There weren't many bursting arrows made by Lu Chen'an before, less than five hundred, but the ten psionic researchers in Zhenyuan City on the ship had been rushing to make them in the past few days, enough to shoot two rounds.

The explosion of the Burst Arrow produces a spirit explosion impact, which belongs to the category that can be offset by the power of the army, similar to the class trait [Aura Arrow], but the power is not enough [Aura Arrow], before the explosion is generated, the arrow itself belongs to the entity, which can produce effective damage.

Fifteen kilometers is already beyond the normal extension of the strength of the army, even if it is barely done, the huge consumption will drag down a large army, and the reason why the demon army can maintain it all the time is because of those soldiers who are constantly marching on the pontoon bridge. These soldiers are like a link, "linking" the demon army on both sides of the strait into a whole, so that this kind of operation becomes the internal dispatch of the army, rather than extending outward.

The fire and exploding arrows temporarily stopped the demonic army's crossing of the lake, and at the same time drained the army protecting the pontoon. The fleet approached the south bank of the Great Lake, avoiding the main force of the demon army on the north shore far away, and pressed directly against the pontoon bridge.

It also has protective etching, but the large building boat is not something that a small pontoon bridge can stop!

Qin Yuliang also opened up the strength of his army at this moment, adding a second layer of protection to the fleet.

At the same time, small boats came from the north, similar to the simple fireboats used in Jiaolong Village before, but the boats were carrying demon troops, not flammable materials, in addition to rafts, such small boats and rafts did not have the qualifications to intercept the building boats, and could only attack! Unfortunately, it was still a step too slow, and the three building boats forcibly crashed into three gaps from the pontoon bridge, and the two sections of the remnant bridge that had lost their connection slowly drifted away under the attraction of the current.

In an instant, a huge gap of two or three hundred meters appeared in the middle of the golden road above the big lake, the demon army on both sides of the strait was cut off, and the main general of the demon army also gave up at the first time to continue to guard the pontoon bridge with the power of the army, there is no point in continuing to drag down the army.

The plan was successful!

But almost at the same time, several black shadows forcibly jumped onto the boat, and there were also figures on the boat and the bamboo raft who kept jumping, hooking the side of the boat one by one, and a large number of figures climbed along the hook rope, trying to board the boat.

Yan Guo jumped high and swept violently at a black shadow that had not yet fallen, and the phoenix wings were gilded with a screaming sound, as if the air was bursting. The general held an axe and spear in his hand and hurriedly resisted, but as the two soldiers collided, the axe and spear were directly knocked out, the tiger's mouth burst, and the body also flew towards the air with huge force, and at the same time, the phoenix wings and gold boring blade that was more than thirty centimeters long cut a long wound in his chest and abdomen, and blood was sprinkled.

As he screamed, an arrow pierced his throat under the cover of the night, stopping the screams.

[System - If you successfully shoot an enemy general with a "dark arrow" on the battlefield, you will be rewarded with +2 Force.] 】

It's so cool to pick up this head!

Zhang Sheng is in a happy mood, the previous embarrassment is gone, this is the right way to open.

Yan Guo, who had stepped into the threshold of internal qi retreat, was more violent than before, although under the cover of the power of the army, many of the means of internal qi separation from the body were greatly reduced, but her physical fitness was further improved, like a humanoid beast, more exaggerated than the demon general strengthened by the abyss breath.

But now is not the time to talk about these, according to the battle plan, this time should be on the south bank, first clear the demon army that crossed Jiaolong Lake before, the most important thing is that the general's [water battle] is C, there is no bonus, and once you land, it belongs to the field, Qin Yuliang is S, and the soldiers can get 30% of the overall strengthening.

As for the lake, just hand it over to Fengqing and the crocodile sailors, as long as you give full play to the advantages of the building boat, there is no big problem.
