【获得白银级随机奖励：八折升级优惠券（500生存点内可用）1、30生存点3、制作属性小幅度提升卡2】

[According to the quality of life of the host yesterday, an additional 205 survival points will be obtained. 】

Survival point balance: 1140

"It's over a thousand!"

Chen Yang only cheered in his heart for a few seconds before his face became serious again. There was a reminder in the system that made him pay special attention.

The reward rating obtained for killing monsters last night was silver.

Unlike hunting the Heartless Poison Cow before, this time when he killed the Iron Wolf and the Vampire Bat, he did not rely on strategy and tricks at all, but a passive counter-kill.

"Even if you don't know that there are monsters coming, if you can make traps in advance to prevent them, the rating after killing the monsters will definitely increase."

Chen Yang recorded the key points of his thoughts in a computer form.

The system calls this kind of behavior 'hunting', but Chen Yang felt that he was more like a prey last night. Under such circumstances, he can get rewards for killing him. Even if he is at the silver level, he is satisfied, but There must be a process of painful experience.

In addition to survival points, the system also presented three prop cards.

The 500% upgrade coupon literally means that the survival points required to upgrade items can be discounted by 40%. Of course, it is only limited to upgrades within [-] survival points, and can save up to [-] survival points.

Make a small attribute improvement card, which can be used when making an item. It can slightly increase the attribute of the item, and there is a very small probability of directly improving the quality of the item.

If it were yesterday, Chen Yang would have bought the upgrade map of the bathroom without hesitation.

A 500% discount coupon for 500 survival points, and the upgrade map for the bathroom just sells for [-] points. Isn't this a combination made in heaven?

But now, Chen Yang decided to use the survival point to continue improving the safety performance of the shelter, at least he had to think about these comfort issues after he felt that there was no problem.

Walking out of the room, Chen Yang began to look at the situation after the robbery.

Sewage mixed with acid rain and blood was everywhere, and the entities of iron wool wolves and vampire bats were stumbling around. It can't be said that the surrounding area of ​​the shelter is a mess, it can only be said to be a mess.

Earthquake, acid rain, and the rampage of wolves and vampire bats, not to mention the surrounding area of ​​the shelter, the shelter itself has been greatly damaged. Chen Yang opened the system interface to check it.

【Stone Shelter】:

......

Integrity: 31% (79 survival points required for repair)

Chen Yang felt like he was alive after a catastrophe. With 31% integrity, if the attack of the wolves continued for a while, the shelter would definitely collapse.

Chen Yang left this mess alone and prepared to collect a wave of basic materials first. After a night of fierce fighting, the key metal materials were basically consumed.

The two scanning opportunities today were all used up. Chen Yang was afraid that some monsters would escape and return, so he gave up his plan to go out to explore, and started collecting directly at the ruins on the edge of the golf course.

The ruins surrounding the golf course are part of the new campus. They are basically rough houses that have just been completed. They haven’t even had time to decorate them. There is nothing but stones, steel bars, and concrete. That’s why he didn’t dig here before. one of the reasons.

But now the situation is special, basic materials are enough, Chen Yang immediately started digging.

The newly made horn spear is fast and sharp. Even if it is not a professional-shaped digging tool, it is more efficient to cut large pieces of ruins than an alloy shovel. In just one morning, Chen Yang collected dozens of units of foundations again. Material.

Now that the ingredients are in hand, Chen Yang is not even in the mood for barbecue today. He simply ate a few slices of Daliba at noon and then returned home.

The first thing to deal with is the shelter that is riddled with holes.

The repair cost of 79 survival points is not too high, more than 30 units of stones are placed on it, and it can be repaired without survival points.

While repairing, Chen Yang also checked the upgrade of the shelter's disaster resistance, that is, the upgrade direction of the shelter.

Upgrade Direction 150: Reinforce the structure and strengthen the ability to resist disasters, [-] survival points are required.

Put 15 units of steel on it, 150 will change to 100, and then put in other materials, but nothing will happen. It is estimated that some high-tech materials that he does not have are needed.

【Are you sure you want to upgrade the shelter upgrade direction [-]? 】

After repeatedly confirming that he could no longer save survival points, Chen Yang clicked 'Confirm'.

The classic upgraded white light enveloped the shelter, and within a minute or two, the entire shelter had been restored to its original state. The cracks on the stone walls disappeared, and all signs of corrosion by acid rain disappeared.

Chen Yang felt the change in the luster on the surface of the stone house at first sight.

The upgraded stone house obviously has an extra layer of transparent material on the outer layer, just like the glass protective film of a mobile phone. This transparent material is the protective film of the shelter.

Chen Yang took a cup made of wood and poured a little acid rainwater on it. The rainwater hit the outer wall without any sign of corrosion, and flowed down the wall directly, without any trace of being wet. Anti-corrosion, even directly has the function of waterproof.

He doesn't study chemistry, so he doesn't know what this material is, but it must be a high-tech thing, and it may also have the effect of heat insulation. Of course, this is not enough to try it with a torch.

As for the anti-shock ability he was most concerned about, there must have been an improvement, but it couldn't be seen from the outside. It was estimated that the internal structure of the stone house had changed.

Generally speaking, the level of earthquake resistance is divided into three levels: anti-seismic, anti-seismic and anti-seismic.

Earthquake resistance is the lowest level, and a shelter without an upgrade is earthquake-resistant. After two major earthquakes, the stone house has not collapsed, which has reached the earthquake resistance level.

The anti-vibration means that when the building is shaking, it will only feel the vibration and will not cause damage to the building. Chen Yang estimates that the upgraded shelter is the level of anti-vibration.

As for the earthquake-proof, it means the same as the literal meaning. When an earthquake occurs, stay in a house that is earthquake-free, and you can't even feel the earthquake.

It is impossible to upgrade the shelter to the earthquake-proof level with 150 survival points. As long as there is an earthquake-proof level, Chen Yang thinks it is enough.

As for upgrading the disaster resistance of the shelter, the consumption of survival points jumped to 1000 points.

Chen Yang summed up another law. Among the upgrade functions, as long as it is necessary to improve the current life, the survival point needs will not exceed the range that he can afford.

For example, to improve the water quality of Quantum Water again, 5000 survival points are required. Judging from his current survival point income, he can upgrade after saving for a week, but it is not necessary.

Another example is the continuous upgrade of the Horn Spear, and the consumption of survival points has also increased to more than a thousand units. Can it be upgraded by saving it?able!But still unnecessary.

The bullhorn spear is already quite powerful, if it is upgraded again, he probably won't even be able to hold this spear.

By analogy, 1000 survival points are needed to upgrade the disaster resistance of the shelter again. It is undeniable that it is definitely useful to continue to upgrade the disaster resistance, but he should not need it now.

With this information, Chen Yang was relieved and at the same time slightly worried. According to this logic, there must be more terrible disasters in the future, otherwise there would be no need for so many upgrade options.
