Su Chen, who had successfully accumulated 1,000 experience points, learned two things that gave him a headache in the system's cordial greetings, and this invasion of the two-headed dog of hell made him feel unlucky for a while.

The staircase of the bell tower was blown up, and Su Chen estimated that he still had fifty minutes to deal with the two-headed dog of hell.

In fact, fighting the two-headed dogs of hell can be done in ten minutes at most, and if you don't succeed in ten minutes, it means that no amount of time is useless.

But there are always surprises, and it's certainly not wrong to leave a little more time to prepare and fight.

After the three stairways were blown up, before the zombies were piled up to the highest enough corpse wall, ordinary first-level zombies could not invade the fourth floor of the bell tower, which relieved a lot of pressure on several teams in Dragon City.

It didn't take long for Su Chen to run out of ammunition that he had brought downstairs this time, and his experience points had increased from 1088 to 1150.

After running out of ammunition, Su Chen returned to the tenth floor, put on new equipment and hurried to the rooftop of the bell tower.

Su Chen picked up the camouflage binoculars, this time starting to check from the periphery of the bell tower, it took thirty minutes, and the Hundred Treasure Eyes barely missed the mutated creatures that appeared in Su Chen's sight inside and outside the Dragon City.

The result of the second pass was the same as the first time, and not a single second-level defensive zombie was found inside and outside Dragon City.

There was not much time left for him, he didn't think about it, his consciousness moved slightly, and once again ordered Shadow to approach the two-headed dog of hell.

What should come will come, and even if he tries to avoid it, he can't change anything after all.

Xiaoying received Su Chen's new order and approached the Helltwo-Headed Dog again.

In the dozens of minutes that Su Chen had consumed in the previous battle, the Helldog Two-Headed Dog had moved a lot of distance, and the ten sentinels around it seemed to be glued to it, and after so much time, Xiaoying still couldn't get close to within twenty meters of it.

Su Chen shook his head, time waits for no one, there are less than twenty minutes left, the Hell Two-Headed Dog can wait forever, but he can't.

Su Chen reconfirmed his equipment, and after making sure that it was correct, Su Chen's consciousness moved slightly, and he and Xiaoying shifted their position.

Before Xiaoying's body completely disappeared, Su Chen appeared where Xiaoying was standing.

Su Chen's face was expressionless, with the force of his left hand, two miniature grenades left a shallow arc in the air, Su Chen's light brown pupils flashed with a cold glow, and the MZ13 held in his right hand continued to erupt steel balls.

The moment the miniature grenade came out of his left hand, Su Chen took out a large handful of MZ13's exclusive deer bullets from his pocket.

The Mz13 is extremely powerful, capable of firing nearly 100 tiny steel balls per shot, and has the disadvantage that it must be reloaded once for one shot.

Su Chen trained the reload speed before coming, and with the action speed of the first-level zombies, it was not comparable to Su Chen's reload speed at all, and he didn't give them a chance to get closer, Su Chen kept reloading and shooting.

The moment Su Chen and Xiaoying switched positions and appeared outside Dragon City, the hell two-headed dog, which had an extremely keen perception, noticed Su Chen for the first time.

It quickly turned around and looked at Su Chen, who was surrounded by corpses not far away.

The two-headed dog of hell had seen Xiaoying, and also knew that Xiaoying could transfer positions with Su Chen, and it was not surprised by Su Chen's sudden appearance, but had some indescribable joy in his heart.

It could sense that Su Chen's combat power was much stronger than it had been at the beginning.

Su Chen, who is armed with a weapon, has been able to fight against the two-headed dog of hell who has lost a head and is at the peak of his combat power.

The Hellhound stood still, not intending to engage in the scuffle or retreating.

The ten sentinels who followed it did not receive new orders, and remained by its side, keeping it safe.

Su Chen's movements were very fast, he knew that the Hell Two-Headed Dog would not leave, he casually threw away the MZ13, held the two Molotov cocktails tied to his back with both hands at the same time, and threw them forward without any consideration.

The moment he threw out the incendiary bottle, miniature grenades rang out from Su Chen's left and right sides, and Su Chen didn't care about the heat wave and energy shock, drew out two Nepalese sabers, and quickly rushed towards the Hellhound.

On the road ahead of Su Chen, the continuous high flame of the Burning Bottle continued to ferment, and the zombies were not afraid of flames, but the high flame could slow them down and destroy their body mechanisms.

If the fire lasts a little longer, their bodies will be completely destroyed.

Su Chen didn't plan to burn them with the Molotov cocktail, he just wanted to use the incendiary bottle to slow them down.

While the incendiary bottle slowed down the zombies, Su Chen also had to pass through hundreds of high-temperature fires.

With such a strong fire, Su Chen could completely burn only his bones, but the moment he walked on the fire, he used the experience potion to restore his injuries.

No sooner had he recovered from his injuries than he was engulfed in flames, and he used the Experience Potion once more.

There is no cooldown time for the use of experience potions, as long as Su Chen has enough experience, he can continue to use them.

This kind of use is only dared by Su Chen before he has advanced to the fourth level of immunity, and if it takes so much, 30 points of experience will be deducted every second.

Every second, Su Chen not only had to consume 30 experience points, but also endured the pain of his skin and organs being burned by the fire three times.

Although the experience potion could instantly restore the injury and erase the pain, Su Chen could not be very punctual when using the experience potion, and he had to endure some pain.

Such repetition was a great torture for Su Chen's spirit.

Su Chen's willpower is already stronger than ordinary people, after the end of the world, Su Chen has had a lot of encounters, and his willpower is forced to train stronger, this bit of high temperature and fire destroys the spirit, Su Chen can still endure it.

Not far away, the Hell Two-Headed Dog was slightly surprised to see Su Chen rushing out of the fire unharmed.

The last time he fought Su Chen, he had seen Su Chen's injuries heal instantly, but he had not seen continuous healing, and it had no effect on Su Chen's actions.

In its memory, there had never been a creature that had not had a negative effect after healing its injuries quickly.

The simplest effects include physical weakness, susceptibility to secondary injuries from wounds, mental exhaustion, etc.

However, Su Chen was still at his peak, as if the previous fire was fake, and his injuries were also fake.

The two-headed dog of hell, who has no less intelligence than a human, does not believe in everything in front of him, but it is indeed a fact that is happening in front of his eyes.

The Hellhound's consciousness moved slightly, and the ten sentinels did not continue to surround it, and quickly rushed towards Su Chen, while the Hellhounds walked slowly, observing Su Chen's movements, looking for an opportunity to strike a fatal blow at him.

Su Chen, who burst out of the flames, quickly encountered ten second-level mutant creatures, and the Nepalese saber frantically harvested their heads.

During the battle, Su Chen put more of his perception on the Helltwo-Headed Dog, as long as it dared to attack, he would resist the full force of the second-level mutant creature, and let the Helltwo-Headed Dog taste the taste of the Nepalese saber cutting off its other head.

Baibaoyan quickly transmitted the latest information of the Helltwo-Headed Dog to Su Chen's brain.

The Hellhound has the same skills and special skills as before, and its combat power still does not match the stats provided.

Su Chen always felt that it had a back hand, and this feeling made him a little uncomfortable.

Su Chen's movements were very fast, and coupled with his way of fighting with injuries for injuries, the second-level mutant creatures couldn't withstand Su Chen's fierce attack at all.

Without giving the hell two-headed dog a chance to find Su Chen's vacancy, Su Chen cut off the heads of the ten weak chicken sentinels.

After cleaning up the ten sentinels, Su Chen once again gathered a large number of zombies around him, Su Chen didn't care about them, and directly knocked them away with his body, and quickly rushed towards the hell two-headed dog.

The strength of the Hell Two-Headed Dog is not weak, and after seeing Su Chen's amazing healing ability, it did not flinch, it roared, and the corpses around Su Chen took a look at the place.

In the next second, all the zombies within a hundred meters of the two-headed dog of hell retreated, creating a clearing that was not too small for them.

The two-headed dog of hell at the peak of its combat power was not afraid of Su Chen, and in Su Chen's previous battles, although it did not find Su Chen's weakness, it at least knew his combat style and gave it some help.

Su Chen snorted coldly, and the two-headed dog of hell chose to go head-on, which made him quite unhappy.

It was obviously confident that it had defeated Su Chen, so it had no intention of borrowing the power of other mutated creatures.

The self-confidence of the two-headed dog of hell saved Su Chen a lot of trouble.

The corners of Su Chen's eyes dropped slightly, and his eyes gradually turned cold, although he was serious in the previous battle, he didn't go all out.

In the battle with the two-headed dogs of hell, he must be prepared to die in battle.

The Helltwo-Headed Dog is different from other mutant creatures, it is powerful, and Su Chen can be deprived of his life by it in an instant if he is not careful.

The Helldog Two-Headed Dog is no easier than Su Chen, it has seen the edge of the Nepalese saber, and knows that once it is slashed, it will inevitably be injured.

The group of corpses retreated, and the battle between Su Chen and the Hell Two-Headed Dog, as one man and one beast looked at each other, jumped up and announced the beginning.

The two-headed dog of hell that lost a head, although its speed was somewhat weakened, it still had a slight speed advantage compared to Su Chen.

In battle, the speed advantage is very important, and the Helldog knows how to use its speed advantage, but Su Chen, who is armed with two knives, is different from other prey, he will not give the Hellhound a chance to sneak up on his back, nor will he wait for it to bite his throat.

The Hellhound's slight speed advantage could only allow it to take the lead, and its speed was not as fast as Su Chen's defense.

Su Chen has two Nepalese sabers for defense, and although the physical defense of the Hell Two-Headed Dog is strong, it is still much worse than the Nepalese saber.

Knowing this, the Hellhound, though has always taken the initiative, will quickly withdraw its arm every time it is about to succeed, avoiding collision with the Nepalese saber.

It needs to create an opportunity for Su Chen to lose the Nepalese Sabre, or it won't be able to do it.

Often, the more intelligent mutant creatures have to worry about in battle, which is good news for Su Chen.

The current Hellhound, because of his worries, looks like a writhing survivor, and Su Chen, who has experience potions and is not afraid of being injured, is like a beast.
