"Brother Lin, don't refuse, it's just a little bit of our mind to help you improve your strength, presumably we will do our best to help you improve, it shouldn't take long for you to improve. Cai Zhong said.

Lin Dong thought about it for a while and didn't refuse, he also thought that his strength would improve quickly, his strength would improve, Luo Qing and they needed help, and he could help them.

"Brother Lin, Xiao Wan and they have recovered, let's start today, what do you think?" Cai Zhong said with a smile.

"Good!"

Lin Dong smiled and nodded, Caizhong Luo Qing is level five, Su Wan Su Yun and Wu Yue are all level four, with their help, plus Lin Dong has already absorbed a lot of energy before, just in just five days, Lin Dong's level has been raised to level four!

"Is this level four?" Caizhong's eyes were full of surprise, they had planned to spend a month to help Lin Dong improve, but in just five days, Lin Dong actually improved, which greatly exceeded their expectations.

Lin Dong smiled: "Thanks to your help, otherwise I wouldn't have reached the fourth level so quickly!"

With Luo Qing's help, Lin Dong could safely and conveniently kill mutant beasts, much faster than his own ascension, and the energy required from level three to level four was much more than the energy needed from level one to level two and level two to level three!

"Brother Lin, can you continue to absorb it?If you can, we will continue to help you level up!" Cai Zhong said.

Lin Dong shook his head: "Brother Cai, this is not necessary, I have already wasted a lot of your time! Moreover, when you reach the fifth level, you can get less energy from hunting the fourth-level mutant beasts, and if you hunt the fifth-level creatures, it will be very dangerous." ”

"Brother Lin, you helped us cure Sister Yun, this has given us a lot of help and saved us a lot of time... Before, we said that it would take about a month to help you upgrade to level four, but now it's only five days!" Luo Qing said, "That's it, no matter if you can upgrade at that time, it's limited to one month, and we won't continue to help you improve until you don't reach level five, how about it?"

Lin Dong thought for a while and said, "Brother Luo, it seems that as long as you kill the mutant beast, you can improve, and the method can be ignored." ”

"That's right, but you can get more energy from killing with your own hands, and if there is a large amount of energy pouring into your body at the same time, it may collapse your body, so some extreme methods are not advisable. Luo Qingdao said.

Lin Dong said: "As long as you can improve quickly, there is no such problem, right?"

"Brother Lin is like this in theory, but in practice it is impossible, no one will not encounter a bottleneck!" Luo Qingdao said.

Lin Dong nodded slightly: "I know, you don't have to help me upgrade, how about you escort for a few days?"

Luo Qing and the others nodded, not to mention that they were just guarding for a few days, there was no problem with guarding for more than ten days or twenty days!

In the few days that they followed Luo Qing and them to kill mutant beasts everywhere, Lin Dong collected a lot of messy things, and Caizhong couldn't see what Lin Dong was collecting those things for, in their opinion, some things were just garbage!

It took two days for Lin Dong to create more than a dozen grenade-sized things, which were powerful bombs!

Lin Dong had absorbed a lot of scientific and technological knowledge, and he could even get a bomb that was enough to kill an immortal emperor-level powerhouse, as long as he had materials and some tools, some small bombs would not be difficult for him!

Under the leadership of Luo Qing and them, Lin Dong approached the territory of the Snake King of the Waste City, the Snake King is one of the few sixth-level mutant beasts in the Waste City, and Su Wan and they suffered in the hands of that Snake King, if it weren't for their cleverness and good strength, they would have died a long time ago!

"You guys just wait here, I'll be here soon!" Lin Dong said, and he immediately rushed out as his words fell.

It was already level four, and the snake step was even more powerful than before, and Lin Dong's figure left hundreds of meters in the blink of an eye!

"That little thing can kill the Snake King?" Su Wan said in disbelief, they knew that the bomb made by Lin Dong was not big, in their opinion, it would be good if a bomb of that size could kill a third- or fourth-level mutant beast.

The Snake King is a sixth-level mutant beast, which is very terrifying!

Luo Qing shook their heads, they didn't think that Lin Dong's bomb had that ability, this was really incredible!

Lin Dong quickly approached a building, according to Luo Qing and the others, the snake king was entrenched in that building!

About a kilometer away from the building, a big snake suddenly raised its head and looked in the direction of Lin Dong, Lin Dong had been discovered!

"Go!"

Lin Dong let out a low cry and smashed out the bomb in his hand, and with the support of his current strength of more than 1,000 kilograms, the bomb quickly crossed a distance of thousands of kilometers and smashed into the building from the broken window.

"Snake step!"

The bomb was thrown, and Lin Dong immediately retreated, much faster than the speed that approached this side before!

The fifth-level mutant snake that discovered Lin Dong also rushed out and quickly chased after Lin Dong, its speed was no slower than Lin Dong, who used snake steps!

Lin Dong and this mutant viper left for less than five seconds, a huge sound sounded behind Lin Dong and them, and a strong shock wave immediately rushed towards Lin Dong and them!

At the center of the explosion, that building shattered in an instant, and the rest of the buildings within a few hundred meters also collapsed!

The blood vaporized in the explosion, and the body of the sixth-level mutant snake king was torn into several pieces in the terrifying explosion! In the building, there were many fifth-level and fourth-level mutant vipers near the building, and they were also torn apart by the force of the explosion!

"Whew!"

The fifth-level mutant snake behind Lin Dong screamed, it was about a hundred meters behind Lin Dong, and it received a relatively strong energy impact, but the energy impact did not hit it hard, it angrily rushed towards Lin Dong at a faster speed!

"Snake step!"

Lin Dong raised his speed to the limit and approached Luo Qing and them, Luo Qing and them were hiding at this moment.

"Kill!"

Lin Dong and the mutant viper arrived at about the same time, and at the moment when the mutant viper was about to attack Lin Dong, Luo Qing and the others made a move, two fifth-level powerhouses and three fourth-level characters attacked together and hit the mutant viper hard in an instant!

"Snake Eat!"

Lin Dong made up for it, this mutant poisonous snake couldn't bear it anymore, and Lin Dong immediately turned into a corpse at this time!

The furious energy immediately rushed into Lin Dong's body, the mutant viper killed by the bomb and the rest of the mutant creatures gushed out a lot of energy, and at this time, the energy of the fifth-level mutant viper killed by Lin Dong poured into Lin Dong's body, Lin Dong felt that his whole body became warm in an instant, and the next moment he broke through to the fifth level!

- If he couldn't break through the bottleneck smoothly, the violent power would make Lin Dong immediately reach the peak of the fourth level, and then his body would be shattered!

And there is another point, if the energy that enters the body at the same time is too terrifying, the body will collapse if it does not have time to break through, how much energy can the body absorb at the same time, this depends on the individual's situation, the same level, some people have a much greater ability to bear!

"Level 5!"

Luo Qing and the others were dumbfounded, they were so fast, a bomb passed, and the powerful energy made Lin Dong go directly to the fifth level!

Moreover, Luo Qing also knew that Lin Dong had not only reached the fifth level, but that there should be a lot of energy left after being promoted to the fifth level!

As far as Luo Qing and the others knew, there were thousands of mutated poisonous snakes gathered in the snake nest of the Mutant Snake King, although some of them were of a lower level, but they couldn't hold up the large number, and they gathered together to be a very huge energy!

"Brother Lin, how do you feel?" said Cai Zhong.

"Wait!"

Lin Dong closed his eyes and checked, and when he reached the fifth level, Lin Dong found that he already had the ability to see inward, but his divine sense was not yet available for the time being, and even if he had a powerful divine sense, he might not be able to open the spatial ring he was carrying.

It has reached different time and space, and the laws of space may be different, and maybe things will never be able to be taken out.

"The cell and the soul absorb energy at the same time... There is actually a snake-like energy swimming in the body. Lin Dong secretly said in his heart, he estimated that the snake-shaped energy was because the crystals he absorbed were left behind by the golden python after he died.

"There is still a lot of free energy in the body, and the accumulation of this free energy is harmful to the body. Lin Dong's mind moved, and he secretly practiced the Nine Dead Demon Skill, he had tried before but failed, and his body had no reaction.

"Huh?"

Lin Dong was pleasantly surprised to find that as he practiced the Nine Death Demon Technique, the free energy in his body gradually moved and merged into the snake-like energy swimming in his body, and with the integration of these energies, the snake-shaped energy body strengthened a little.

This serpentine energy should be the source of the skill, although it has not yet been verified, but Lin Dong feels that his skill should be enhanced!

"It takes a few days to refine this energy. Lin Dong opened his eyes thinking in his heart, Caizhong showed a look of concern in their eyes, Lin Dong smiled at them and said, "Fortunately, do you still have any mutant creatures that you wanted to deal with before but couldn't deal with?"

Cai Zhong exclaimed: "Brother Lin, do you still want to blow up intermittently? This is very dangerous, the violent energy may directly tear your body! This kind of thing is not unprecedented, some people directly use fire to burn mutant creatures in the wild, although they burn a lot to death, but they die in the end! We have also heard of bombs, and there are also those who kill themselves!"

"It should be fine for the time being, don't forget that my medical skills are okay, and I know my physical condition quite well. Lin Dong said with a smile.

Hearing Lin Dong say this, Cai Zhong and they were a little relieved, they lived on this side, and the mutant creatures here wanted to be destroyed, and soon they brought Lin Dong and them to the vicinity of the place where some mutant creatures gathered, there were no sixth-level mutant creatures here, but there were many fifth-level mutant creatures, and if they were all killed, there would definitely be no problem with half of the energy there before.

"You're waiting here... Don't worry, I'm already level five now, it's very difficult for them to kill me!" Lin Dong said with a smile, as a person who had once reached the Immortal Emperor level, Lin Dongruo might as well die if he didn't have such confidence!
