"Brother Lin, don't refuse. Helping you improve your strength is just a little bit of our heart. I believe we will do our best to help you improve. It won't take long for you to improve." Cai Zhong said.

Lin Dong thought about it for a while but did not refuse. He also wanted to improve his strength quickly and improve his strength. Luo Qing and the others could help them if they needed help.

"Brother Lin, Xiaowan and the others have recovered. Let's start today. What do you think?" Cai Zhong said with a smile.

"good!"

Lin Dong nodded with a smile. Cai Zhong Luo Qing was level 5, Su Wan, Su Yun and Wu Yue were level 4. With their help, and Lin Dong had already absorbed a lot of energy before, but in just five days, Lin Dong's level had been upgraded to level 4!

"This is level 4?" Cai Zhong and the others were full of surprise. They planned to spend a month helping Lin Dong improve, but in just five days, Lin Dong actually improved, which was much faster than their expectations.

Lin Dong smiled and said, "Thanks to your help, otherwise I wouldn't have reached Level 4 so soon!"

With the help of Luo Qing and others, Lin Dong can safely and conveniently kill mutant beasts, which is much faster than himself. The energy required for level three to level four can be more than the energy required for level one to level two to level two to level three!

"Brother Lin, can you continue to absorb? If possible, we will continue to upgrade you!" Cai Zhong said.

Lin Dong shook his head: "Brother Cai, there is no need for this. I have wasted a lot of your time! Moreover, when you reach level 5, hunting level 4 mutant beasts gets less energy. If you hunt level 5 creatures, it is very dangerous."

"Brother Lin, you helped us cure Yunmei and the others. This has given us great help and saved us a lot of time... We said that we had helped to level 4, so we calculated it for about a month, but now it is only five days!" Luo Qing said, "Let's do this, no matter whether you can upgrade at that time, it is limited to one month. If you don't reach level 5, we will not continue to help you improve. How about it?"

Lin Dong thought for a while and said, "Brother Luo, it seems that you can improve by killing the mutant beast, and you can ignore the method."

"That's right, but you get a lot of energy by killing yourself, and if a large amount of energy flows into the body at the same time, it may cause the body to collapse, so some extreme methods are not advisable." Luo Qing said.

Lin Dongdao: "As long as you can improve quickly, there will be no such problem, right?"

"Brother Lin is like this in theory, but in fact it is impossible. No one will not encounter a bottleneck!" Luo Qing said.

Lin Dong nodded slightly: "I know, there is no need to help me upgrade. Please help me with how many days to protect you?"

Luo Qing and the others nodded. Not to mention just guarding for a few days, there is no problem with guarding for more than ten days and twenty days!

After following Luo Qing and the others killed mutant beasts everywhere, Lin Dong collected a lot of messy things. Cai Zhong and the others couldn't see what Lin Dong collected those things. In their opinion, some of the 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 has absorbed a lot of scientific and technological knowledge, and he can even get bombs that are enough to kill the Immortal Emperor-level powerhouse. As long as there are materials and some tools, some small bombs will not defeat him!

Under Luo Qing and others' leadership, Lin Dong approached the territory of the Snake King in the Waste City. The Snake King is one of the small number of Level 6 mutant beasts in the Waste City. Zhiyou Su Wan and the others suffered a loss in the hands of that Snake King. If they weren't for their cleverness and good strength, they would have died long ago!

"You guys are waiting here, I'll come over soon!" Lin Dongdao, and he rushed out immediately after he finished speaking.

He has already level 4 and the snake step is even more powerful than before. Lin Dong's figure left hundreds of meters in the blink of an eye!

"Can the little thing kill the snake king?" Su Wan said incredible. They knew that the bombs created by Lin Dong were not big. In their opinion, it would be good if the bombs of that size could kill a level 3 and 4 mutant beast.

The Snake King is a level 6 mutant beast, which is very terrifying!

Luo Qing and the others shook their heads. They didn't think Lin Dong's bomb had that ability. This was incredible!

Lin Dong quickly approached a building. According to Luo Qing and the others, the Snake King was entrenched in that building!

About a thousand meters away from the building, a big snake suddenly raised its head and looked towards Lin Dong's direction. Lin Dong had been discovered!

"go!"

Lin Dong shouted softly and smashed the bomb in his hand. With the support of his current force of more than 1,000 kilograms, the bomb quickly crossed a thousand meters and smashed it into the building from the broken window.

"Snake Step!"

When the bomb was thrown out, Lin Dong immediately retreated, and the speed was much faster than before when he approached this side!

The level 5 mutant poisonous snake that Lin Dong also rushed out and chased Lin Dong quickly. Its speed was no slower than that of Lin Dong who used the snake step!

Lin Dong and the mutated poisonous snake left less than five seconds, and a huge sound rang behind Lin Dong and the others, and a strong shock wave immediately rushed towards Lin Dong and the others!

In the center of the explosion, the building instantly shattered, and the rest of the buildings within a few hundred meters also collapsed!

The blood was vaporized in the explosion, and the mutated snake king of level 6 was torn into several pieces in the terrifying explosion! In the building, there were many mutated poisonous snakes of level 5 and level 4 near the building, and they were also torn to pieces by the explosion force!

"Ao!"

The level five mutant poisonous snake behind Lin Dong screamed. It was about a hundred meters behind Lin Dong and was hit by a relatively strong energy impact, but the energy impact did not hurt it severely. It rushed towards Lin Dong angrily at a faster speed!

"Snake Step!"

Lin Dong raised his speed to the limit and approached Luo Qing and the others, who were hiding now.

"kill!"

Lin Dong and the mutant venomous snake arrived at almost the same time. At the moment when the mutant venomous snake was about to attack Lin Dong, Luo Qing and the others took action. Two level five strong men and three level four characters took a sneak attack and instantly injured the mutant venomous snake!

"Snake-eating!"

Lin Dong made up for it. This mutated poisonous snake could no longer bear it. Lin Dong immediately turned into a corpse!

The violent energy immediately rushed into Lin Dong's body. The mutated poisonous snake killed by the bomb and the many energy gushed out by the other mutated creatures. At this time, the energy of the fifth-level mutated poisonous snake killed by Lin Dong rushed into Lin Dong's body. Lin Dong felt that his whole body became warm in an instant, and he broke through to level 5 in the next moment!

——If you cannot successfully break through the bottleneck, the violent power will immediately reach the peak of level 4, and then it will shatter his body!

And there is another point. If the energy entering the body at the same time is too terrifying, the body will collapse if it cannot break through. How much energy the body can absorb at the same time depends on the individual's situation. Some people have much greater ability to withstand at the same level!

"Level 5!"

Luo Qing and the others were stunned. It was so fast that a bomb passed by, and the powerful energy made Lin Dong reach level 5 directly!

Moreover, Luo Qing and others knew that Lin Dong was not only at level 5, but there should be a lot of energy left after upgrading to level 5!

As far as Luo Qing and the others know, there are thousands of mutant poisonous snakes gathered in the snake nest of the mutant snake king. Although some are lower in level, they cannot withstand the number of them. When they gather, they are a very huge energy!

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

"etc!"

Lin Dong closed his eyes and checked. At level 5, Lin Dong found that he had the ability to see inwardly, but his spiritual consciousness was not yet available. Even if he had a powerful spiritual consciousness, he might not be able to open the space ring he was carrying.

It has reached different time and space, and the laws of space may be different. Maybe things can never be taken out.

"Cells and soul absorb energy at the same time... There is actually snake-shaped energy in the body." Lin Dong said in his heart. He estimated that the snake-shaped energy was because the crystal he absorbed was left behind after the death of the golden python.

"There is still a lot of free energy in the body. The accumulation of these free energy is harmful to the body." Lin Dong secretly practiced the Nine-Death Demonic Art with a thought. He had tried it before but his body had no reaction.

“Huh?”

Lin Dong was surprised to find that as he practiced the Nine-Death Demon Magic, the free energy in his body gradually moved and merged into the swimming snake-shaped energy in his body. As these energy was integrated, the snake-shaped energy body increased a little.

The serpentine energy should be the source of the skill. Although it has not been verified yet, Lin Dong feels that his skills should be enhanced!

"How many days will it take to refine these energy?" Lin Dong thought in his heart and opened his eyes. Cai Zhong and his friends showed concern in their eyes. Lin Dong smiled at them and said, "Fortunately, do you have any mutated creatures you want to deal with but cannot deal with before?"

Cai Zhong said in surprise: "Brother Lin, do you still have to blow it off? This is very dangerous. The violent energy may tear your body directly into pieces! There are some people who use fire to burn mutant creatures in the wild. Although they burn a lot of them, they end up dying! We have also heard of bombs, and some people who have also supported themselves to death!"

"It should be fine for the time being. Don't forget that my medical skills are OK. I am quite familiar with my physical condition." Lin Dong said with a smile.

Cai Zhong and the others felt a little relieved when they lived here. They wanted to destroy the mutant creatures here, and soon they brought Lin Dong and the others to the near where some mutant creatures gathered. There were no mutant creatures at level 6, but there were many mutant creatures at level 5. If they were all killed and killed, they would definitely be fine to get half of the energy there before.

"You guys are waiting here... don't worry, I'm already level 5 now, it's hard for them to kill me!" Lin Dong smiled. As a figure who once reached the Immortal Emperor level, Lin Dongruo's confidence is worse than him!
