"It's coming!" Listening to the dense footsteps in the tunnel, Guo Dafu reminded the people beside him.

The people who had been prepared immediately brought a large amount of wet wood, and then took the initiative to dig the last section of the tunnel, and under the surprised eyes of the rat-man warriors and steel-toothed rats below, they lit bundles of wet wood and threw them into the tunnel.

After the wet wood was ignited, a choking smoke was immediately emitted during the burning process, which not only completely obscured the sight of the fierce beasts in the tunnel, but also made the rat warriors and steel-toothed rats quickly feel a hot pain in their lungs.

Some steel-toothed rats tried to crawl out of the tunnel, but as soon as they emerged, a dozen spears stabbed at the entrance of the hole, piercing them into a sieve, and the defenders had already found out, and this burrow attack tactic was completely dead.

After getting rid of the steel-toothed rats who wanted to crawl out of the hole, Guo Dafu and the others got several big fans, and kept fanning the wind at the entrance of the cave, so that the wet wood burned more violently and emitted more smoke.

This trick is really too bad, the wet wood burns more violently, and the oxygen in the tunnel is consumed faster, and the fierce beasts and nezumi warriors trapped in the tunnel behind them breathe the poisonous smoke that fills the entire tunnel.

At this time, no matter how strong you are, it is useless, as long as you are not to the point where you don't need to breathe, in this environment, you will have to burp for a long time.

So these fierce beasts and nezumi warriors all wanted to exit the tunnel as soon as possible, but unfortunately, in this extremely narrow tunnel, these hurried and panicked people did not give in to each other, and it was easy to completely block the tunnel.

By the time the nezumi commander on the other side of the tunnel found out that there was smoke coming out of the tunnel, it was already too late, and most of the fierce beasts and nezumi warriors inside had already choked to death with the poisonous smoke, and only a few who were relatively close to the tunnel entrance still had a breath left.

Soon, among those tunnels, they were poured into the river by Guo Dafu and them, making them unusable.

At this point, the nezumi commander's cave attack tactics can be said to have completely failed, and he also lost the lives of thousands of fierce beasts and nezumi warriors.

The rat-man commander, who found out that the cave attack fighters had completely failed, quickly decided to adopt a strong attack tactic, although the casualties in this fight would be a little larger, but it would be absolutely difficult for the enemy to come up with a way to crack it.

And this time he led tens of thousands of troops, and he didn't believe that he couldn't gnaw on such a small stronghold.

Soon, a new round of offensive by the beasts began, this time it was not a feint like last time, and the real attack, there were many elite rat soldiers belonging to the Steel-toothed Rat King, and a lot of various siege equipment were also dispatched.

Guo Dafu also saw that the other party was serious this time, so he didn't dare to be careless, and immediately led everyone to the city wall to prepare for the battle.

In order to protect those siege equipment, this time the enemy army made a lot of that kind of large tower shields, with these tall and thick tower shields in front of them, even those large bed crossbows are difficult to hurt the rear siege equipment, in desperation, Guo Dafu can only let those bed crossbows attack those rat soldiers and rat warriors who are not protected by tower shields.

And to attack these rat soldiers and nezumi warriors, those bed crossbows are still full of lethality, and every crossbow arrow fired can take the lives of at least two or three steel-toothed rats.

However, those siege equipment Guo Dafu will not completely ignore, when the enemy's tower shields and siege equipment are close to about two hundred meters, he will let the crossbowmen on the city wall continue to fire arrows at those tower shields and siege equipment, among which those bows and arrows can be completely used to throw around the tower shield in front, and these crossbowmen shoot rockets that have been prepared a long time ago.

And those tower shields and siege equipment, the main body of which was wooden, was shot by this dense rocket, and soon ignited a fire and was burned into a pile of charcoal.

After some of the tower shields were burned, the catapults and other siege equipment behind them were exposed, and the bed crossbows in the arrow towers immediately seized the opportunity to fire at these siege equipment.

And many of those catapults also began to fire back at the city wall, after each stone bullet hit the city wall, it will make the city wall tremble, but fortunately, this earthen wall is still strong, although it was bombarded by the stone bullet trembling, after all, it did not collapse, Guo Dafu They also seized the time to keep firing bows and arrows in Chengtou Mountain, killing and injuring many enemy troops under the city wall.

Suddenly, one of the arrow towers closest to Guo Dafu was hit by a stone projectile thrown by a catapult, and most of it was smashed down with a bang, and the large bed crossbow inside was also smashed out and fell to the city wall.

Seeing this, those fierce beasts and rat people immediately burst out into excited shouts, after all, these large bed crossbows are too threatening to them, even those rat general-level existences, once they are hit by the giant crossbow arrows they shoot, they will be killed in seconds, and now they can smash down an arrow tower of the enemy army, which is naturally worth cheering.

"Damn brutes, don't rejoice too soon!" Guo Dafu roared, strode to the collapsed arrow tower, kicked away a few crossbars that were pressed on top of the bed crossbow, and then dragged the bed crossbow out of the pile of rubble.

Then Guo Dafu asked several pioneer warriors beside him to fix the bed crossbow hard, and he himself found a giant crossbow arrow from the ruins, and then grabbed the thick bowstring of the giant bed crossbow with both hands, and shouted, "Open!" Suddenly, both arms were enlarged because of the mana, and the bowstring of the giant bed crossbow was pulled apart by manpower.

After a pioneer on the side loaded the crossbow arrow, Guo Dafu slightly adjusted the direction of the bed crossbow and fired the crossbow at a huge steel-toothed rat that was screaming the most excitedly.

This steel-toothed rat is more than three meters long, and it is obviously already at the level of a rat general, and the moment he saw the crossbow aimed at him, this beast suddenly couldn't laugh, and immediately wanted to dodge.

Unfortunately, before it could dodge, Guo Dafu had already launched the giant crossbow arrow.

With a pop, the bolt shot right into the mouth of the rat general, and then easily pierced its entire head, flying out of the back of its head, and nailing the two rat soldiers behind it to the ground.

The pierced head spurted a mouthful of blood from its mouth, and soon fell to the ground weakly, convulsing in pain.

Guo Dafu was also shocked to see that he had really succeeded in pulling open this bed crossbow and launching the crossbow arrow, thinking that after he broke through to the innate realm, his body had really been fully strengthened! The power that can burst out in an instant is much stronger than before.

And now that he can even force this kind of giant bed crossbow open, can't those strong bows with greater pull force also be able to pull away! When the time comes, you don't need to use this kind of strong bow to snipe those large-sized powerful beasts, and you don't need to be too accurate, after all, those fierce beasts are so big, they are all good targets!

After opening the mall and checking it, Guo Dafu found that there were indeed all kinds of bows and arrows with different pulling forces.

Guo Dafu chose a strong bow with a pulling force of 2,000 kilograms, which is not expensive, it only needs 20 points to redeem, and it also comes with two large bags of special arrows.

A bow with such a large pull force really has to be specially equipped with arrows, after all, the higher the pull of the bow and arrow, the heavier the arrows must be. Otherwise, the arrow is too light, and after the arrow is shot, the kinetic energy accumulated by the war bow itself will not be released cleanly, and in the end it can only be transmitted to all parts of the bow body, causing the bow body to vibrate violently and damage the bow body. This is also the reason why the bow and arrow are not allowed to be empty, if it is empty, the accumulated strength will all have to be consumed by the bow itself, and the bow will be injured at light, and the bow will explode directly at the worst, which is really a very dangerous behavior.

Guo Dafu carried the super hard bow that had just been exchanged, pulled the bowstring, and found that it was indeed much higher than the ordinary war bow he used before, but with his current strength, it would not be too laborious to pull the bow, and it was a more suitable kind. In comparison, if the bow is drawn too hard, the archer may not be able to shoot a few arrows and will be tired, and in that state, the archer's arm may tremble because of too much force, which greatly reduces the accuracy of the bow and arrow.

Therefore, the choice of bow and arrow is not to choose the greater the pull, the better, but to choose the kind that suits you, only in this way can you better exert the power of the bow itself.

Guo Dafu pulled out another arrow, and found that this arrow was much heavier than the ordinary arrows used in the previous war bow, and its arrow body looked like it was made of military steel, and the arrow was the kind of triangular pyramid shape that was extremely sharp at first glance and had a strong armor-piercing ability.

At this time, a fat rat general happened to enter Guo Dafu's sight, so he immediately opened his bow and arrow, aimed at the other party, and took this fat rat general as the first target of his new bow and arrow.

When Guo Dafu released the bowstring and shot the arrow, the arrow immediately flew out under the impetus of huge kinetic energy, and almost instantly broke through the speed of sound, emitting a short sonic boom, and the next moment it hit the side of the rat, easily piercing its chest like a tofu, and then shot out from the other end, plunging into the ground.

Because all this happened too quickly, the rat general didn't seem to notice that he was injured at first, and after knowing that the sharp pain at the wound spread to his brain, the rat general found out that he was injured, and then in addition to the severe pain, there was also the pain of suffocation, because Guo Dafu's arrow penetrated his chest, and naturally pierced the lungs in his chest, so that its lungs were like pierced car tires, leaking.

As the rat spat out a mouthful of red foamy blood, the strength of its body also passed quickly, and its huge body collapsed, pressing a passing rat soldier directly under its body.
